Published: July 2021

PurposeSocial media technology has changed donors' decision-making process in online philanthropy compared with traditional charity. How do IT affordances support donor perceptions and motivations in charitable crowdfunding? The purpose of this study is to explore how the five sub-dimensions of charitable crowdfunding IT affordances (i.e. visibility, association, meta-voicing, trading and security) afford initiators and platforms in motivating donors to support charitable crowdfunding projects.Design/methodology/approachThis paper uses a quantitative research approach. An online survey was conducted to collect research data from WeChat users who had experienced charitable crowdfunding. A sample of 344 valid responses were received and analyzed.FindingsThe results show that four of the five IT affordances facilitate donors' perceptions (perceived emotions and trust) and motivations (intrinsic motivations and extrinsic motivations), and thereby increase behavioral intention on supporting charitable crowdfunding projects.Originality/valueThis study advances the affordances and online charity literature by examining the antecedents and outcome of perceptions and motivations that determining behavioral intention in more detail. The authors’ findings not only benefit researchers in explaining how technology helps donors perceiving projects and motivating them to donate online, but also assists practitioners in developing better charitable crowdfunding management strategy.
Will the development of the financial industry cause environmental pollution?
Authors: Xing Lu , Yi Xiaojing , Zhang Ying 
Published: July 2021

PurposeA series of environmental pollution issues and economic improvement go hand in hand. Since financial listed companies contribute significantly to the national economic development, China has been paying increasing attention to the development of the financial industry. The purpose of this paper is to explore the relationship among the development level of the financial industry, over-investment of the listed companies and environmental pollution through a macro-level and micro-level mechanism.Design/methodology/approachIn this study, we adopt the 2011–2017 panel data of listed companies in the manufacturing industry to study the impacts of the financial industry on environmental pollution. Meanwhile, the paper uses a mediator model, and over-investment is introduced to the econometric model as a mediator to explore whether the development of the financial industry can affect the environmental pollution through over-investment.FindingsA U-shaped relationship between financial industry development and environmental pollution was observed through a macro-perspective; additionally, over-investment of the listed companies significantly increased environmental pollution, along with a significant mediator effect of over-investment. A significant positive correlation was observed between financial industry development and environmental pollution in the East region of China, while the correlation was negative in the Central and West regions. The mitigation effect of financial industry development on environmental pollution was more significant in the low-end manufacturing industry, compared with basic and high-end manufacturing industries.Originality/valueStrengthening the incentives and supervision toward company managers, reducing over-investment behaviors, encouraging suitable financial industry development to reduce financial risks, improving environmental conservation laws and regulations, and implementing stringent penalty mechanisms for environmental conservation are necessary.

Published: July 2021

PurposeThe authors examine predictors of self-legitimacy for police officers belonging to the Military Police force of São Paulo (Brazil). Considering the variables mobilized by the literature on self-legitimacy, the authors seek to identify what explains the self-legitimacy of militarized police officers.Design/methodology/approachA survey was applied to 298 frontline police officers in the city of São Paulo, analyzing indicators separated into two groups: relationship dimension and organizational dimension. An ordinary least square model is used to test the “relationship” and “organizational” variables on police officers' self-legitimacy.FindingsEffectiveness is the strongest predictor for self-legitimacy. Organizational justice and distributive justice also present important effects, as the perception of citizens' attitudes toward police reinforces the conception of self-legitimacy as a dialogical construct, comprising here the public's expectations of police work as well as the police officers' perceptions that they are respected and considered important by the public.Originality/valueThere are no other studies on self-legitimacy related to Brazilian police officers or exploring these aspects among police officers submitted to a militarized structure. These results contribute to the ongoing debate on the militarization of police activities and their possible effects on police legitimacy.
A printability assessment framework for fabricating low variability nickel-niobium parts using laser powder bed fusion additive manufacturing
Authors: Zhang Bing , Seede Raiyan , Whitt Austin , Shoukr David , Huang Xueqin , Karaman Ibrahim , Arroyave Raymundo , Elwany Alaa 
Published: July 2021

Purpose
There is recent emphasis on designing new materials and alloys specifically for metal additive manufacturing (AM) processes, in contrast to AM of existing alloys that were developed for other traditional manufacturing methods involving considerably different physics. Process optimization to determine processing recipes for newly developed materials is expensive and time-consuming. The purpose of the current work is to use a systematic printability assessment framework developed by the co-authors to determine windows of processing parameters to print defect-free parts from a binary nickel-niobium alloy (NiNb5) using laser powder bed fusion (LPBF) metal AM.

Design/methodology/approach
The printability assessment framework integrates analytical thermal modeling, uncertainty quantification and experimental characterization to determine processing windows for NiNb5 in an accelerated fashion. Test coupons and mechanical test samples were fabricated on a ProX 200 commercial LPBF system. A series of density, microstructure and mechanical property characterization was conducted to validate the proposed framework.

Findings
Near fully-dense parts with more than 99% density were successfully printed using the proposed framework. Furthermore, the mechanical properties of as-printed parts showed low variability, good tensile strength of up to 662 MPa and tensile ductility 51% higher than what has been reported in the literature.

Originality/value
Although many literature studies investigate process optimization for metal AM, there is a lack of a systematic printability assessment framework to determine manufacturing process parameters for newly designed AM materials in an accelerated fashion. Moreover, the majority of existing process optimization approaches involve either time- and cost-intensive experimental campaigns or require the use of proprietary computational materials codes. Through the use of a readily accessible analytical thermal model coupled with statistical calibration and uncertainty quantification techniques, the proposed framework achieves both efficiency and accessibility to the user. Furthermore, this study demonstrates that following this framework results in printed parts with low degrees of variability in their mechanical properties.
Experimental study on tensile strength of copper microparticles filled polymer composites printed by fused deposition modelling process
Authors: Adibi Hamed , Hashemi Mohammad Reza 
Published: July 2021

Purpose
The purpose of this paper is to investigate the variables of the fused deposition modelling (FDM) process and improve their effect on the mechanical properties of acrylonitrile butadiene styrene (ABS) components reinforced with copper microparticles.

Design/methodology/approach
In the experimental approach, after drying the ABS granule, it was mixed with copper microparticles (at concentrations of 5%, 8% and 10%) in a single screw extruder to fabricate pure ABS and composite filaments. Then, by making the components by the FDM process, the tensile strength of the parts was determined through tensile strength tests. Taguchi DOE method was used to design the experiments in which nozzle temperature, filling pattern and layer thickness were the design variables. The analysis of variance (ANOVA) and signal-to-noise analysis were conducted to determine the effectiveness of each FDM process parameter on the ultimate tensile strength of printed samples. Following that, the main effect analysis was used to optimize each process parameter for pure ABS and its composite at different copper contents.

Findings
The study allows the layer thickness and filling pattern had the highest effects on the ultimate tensile strength of the printed materials (pure and composite) in the FDM process. Moreover, the results show that the ultimate tensile strength of the ABS composite containing 5% copper was nearly 12.3% higher than the pure ABS part. According to validation tests, the maximum error of experiments was about 0.96%.

Originality/value
In this paper, the effect of copper microparticles (as filling agent) was investigated on the ultimate tensile strength of printed ABS material during the FDM process.

Authors: Bharwani Sonia , Mathews David 
Published: July 2021

PurposeThis study is an empirical exploration of the tech-based transformation strategies being adopted by luxury hotels in India to assuage the fear psychosis and restore guest confidence in the context of the COVID-19 pandemic. It sheds light on the “new normal” and its overarching implications for hotel operations from the user experience perspective.Design/methodology/approachA mixed method strategy was adopted for data collection. Qualitative data was gathered from a video analysis of two webinars with high-profile panels of thought leaders about the challenges arising from the global health crisis and related post-pandemic recovery strategies. This data has been triangulated with desk research and data collected through an online survey which sought to map guest sentiments with respect to resuming the use of hospitality services and their attitude towards the proposed tech transformation initiatives in the Indian luxury hospitality industry.FindingsThe research data indicates that despite their pandemic-related trepidations, people still have a strong urge to be social and to travel. Technology can play a pivotal role in creating safe spaces for social distancing, facilitating a contactless guest interface to alleviate guest concerns for safe hygiene and rebuilding customer confidence to address the trust deficit.Practical implicationsHospitality organisations must be discerning in the investments they make in new technology and contactless experiences because hasty investments in extensive automation may be perceived as gimmicky by guests. Intelligent and astute use of technology tools can minimise human error, optimise service efficiency and enhance guest experience through elevated levels of personalised hospitality in luxury hotels by judiciously marrying high touch with high tech.Originality/valueThis study is the one of the first empirical explorations of the tech transformation strategies adopted by luxury hotels in the Indian context in response to the COVID-19 pandemic. It explores their efforts for the continued co-creation of high value experiences based on consumer perspectives, with implications for both hospitality and tourism theory and practice.

AbstractAtopic dermatitis (AD) mostly develops in early childhood and tends to resolve with age. However, its time course in severity before and after adolescence varies widely among patients. To investigate the course of disease severity from birth to 19 years old of adult patients with AD, we conducted a nationwide Web‐based survey of 3090 Japanese adult subjects diagnosed with AD, using a questionnaire to choose a pattern that most resembled their own out of 10 courses of AD severity. Patients in the 20s and 30s age groups tended to choose the option “gradually improved” or “improved by the age of 12”, but patients in the 40s or older age group tended to choose the option “aggravation between the age of 12 and 19”. Those who chose “AD development at age 20 or older” increased as the generation was older. This survey revealed that the time course of AD severity from birth to 19 years old varies depending on the generation targeted in this study. It is presumed that the acquired factors affecting the natural history of AD have changed over the past 50 years in Japan.
The effect of lanthanum on growth and gene expression in a facultative methanotroph
Authors: Crombie Andrew T. 
Published: July 2021

SummaryThe biological importance of lanthanides has only recently been identified, initially as the active site metal of the alternative methanol dehydrogenase (MDH) Xox‐MDH. So far, the effect of lanthanide (Ln) has only been studied in relatively few organisms. This work investigated the effects of Ln on gene transcription and protein expression in the facultative methanotroph Methylocella silvestris BL2, a widely distributed methane‐oxidizing bacterium with the unique ability to grow not just on methane but also on other typical components of natural gas, ethane and propane. Expression of calcium‐ or Ln‐dependent MDH was controlled by Ln (the lanthanide switch) during growth on one‐, two‐ or three‐carbon substrates, and Ln imparted a considerable advantage during growth on propane, a novel result extending the importance of Ln to consumers of this component of natural gas. Two Xox‐MDHs were expressed and regulated by Ln in M. silvestris, but interestingly Ln repressed rather than induced expression of the second Xox‐MDH. Despite the metabolic versatility of M. silvestris, no other alcohol dehydrogenases were expressed, and in double‐mutant strains lacking genes encoding both Ca‐ and Ln‐dependent MDHs (mxaF and xoxF5 or xoxF1), growth on methanol and ethanol appeared to be enabled by expression of the soluble methane monooxygenase.
Jobs and job quality between the eve of the Great Recession and the eve of COVID‐19
Authors: Bourquin Pascale , Waters Tom 
Published: July 2021

AbstractIn 2019, the employment rate among 25‐ to 64‐year‐olds in the UK reached 80 per cent – the highest on record, and considerably higher than the 76 per cent rate recorded shortly before the Great Recession. In this paper, we investigate the growth in employment between the eve of the Great Recession and the eve of COVID‐19 across several dimensions. We analyse which sectors, demographic groups and regions accounted for the rise. We also investigate how job ‘quality’ – in both financial and non‐financial terms – has changed. We find that almost all demographic groups and regions saw a rise in employment, especially those with low pre‐existing employment rates and those near the bottom of the income distribution. Hourly pay growth was very weak over the period, with the median actually slightly falling. Other indicators of job quality show a more mixed picture: employees seem to have greater appreciation of their work and firm, but perceive less security and flexibility in their job.
Long‐run growth of ambulatory surgery centers 1990–2015 and Medicare payment policy
Authors: Munnich Elizabeth L. , Richards Michael R. 
Published: July 2021

AbstractObjectiveTo examine long‐run growth in the ambulatory surgery center (ASC) industry and potential factors influencing its trajectory.Data sourcesNational data for all Medicare‐certified ASCs (1990–2015) and outpatient discharge records from the state of Florida in 2007.Study DesignWe documented the number of ASCs in the United States over time and decomposed the trend into underlying ASC market entry and exit behavior. We then examined the plausibility of 2008 Medicare payment reforms to influence the trend changes.Data Extraction MethodsData on ASC openings and closures are obtained from the Centers for Medicare and Medicaid Services Provider of Service files. Secondary data on ASC volume in Florida are obtained from the Florida Agency for Health Care Administration.Principal FindingsThe number of ASCs in the United States grew 5%–10% annually between 1990 and 2007 but by 1% or less beginning in 2008. This change coincided with substantive reductions in Medicare payments for key ASC services. The annual number of new ASCs was as much as 50% lower following the payment change.ConclusionsASCs are an important competitor for outpatient services, but growth has slowed dramatically. Sharp changes in new ASC entry align with less generous Medicare fees.
Energy and crop price cycles before and after the global financial crisis: A new approach
Authors: Vatsa Puneet , Miljkovic Dragan 
Published: July 2021

AbstractUsing the newly developed Hamilton filter, we decompose prices of three primary energy sources (crude oil, coal and natural gas) and five significant crops (corn, palm oil, rice, soybean and wheat) to isolate their cyclical components. Then, we apply time‐difference analyses to study their co‐movement. Analysing 15 energy price–crop price pairs over two periods, 1990–2009 and 2010–2020, we find that the correlations between coal and crop prices have weakened significantly during the 2010s, while correlations of crude oil and natural gas prices with crop prices have strengthened. Until 2009, crude oil and natural gas prices led crop prices, whereas during the 2010s they lagged crop prices. We conclude that the global financial crisis marked a pivotal shift in the associations between energy and crop prices. The results underscore the importance of examining the associations between specific crop and energy prices rather than aggregated indices; furthermore, using crude oil as a proxy for energy prices is not suitable—an aggregated approach that presumes the predominance of one energy source apropos different crops may yield incorrect results.

Published: July 2021

AbstractMicrobial growth and fluctuations in environmental conditions have been shown to cause microbial contamination and deterioration of food. Thus, it is paramount to develop reliable strategies to effectively prevent the sale and consumption of contaminated or spoiled food. Responsive packaging systems are designed to react to specific stimuli in the food or environment, such as microorganisms or temperature, then implement an informational or corrective response. Informative responsive packaging is aimed at continuously monitoring the changes in food or environmental conditions and conveys this information to the users in real time. Meanwhile, packaging systems with the capacity to control contamination or deterioration are also of great interest. Encouragingly, corrective responsive packaging attempting to mitigate the adverse effects of condition fluctuations on food has been investigated. This packaging exerts its effects through the triggered release of active agents by environmental stimuli. In this review, informative and corrective responsive packaging is conceptualized clearly and concisely. The mechanism and characteristics of each type of packaging are discussed in depth. This review also summarized the latest research progress of responsive packaging and objectively appraised their advantages. Evidently, the mechanism through which packaging systems respond to microbial contamination and associated environmental factors was also highlighted. Moreover, risk concerns, related legislation, and consumer perspective in the application of responsive packaging are discussed as well. Broadly, this comprehensive review covering the latest information on responsive packaging aims to provide a timely reference for scientific research and offer guidance for presenting their applications in food industry.
