The purpose of this paper is to study the following two issues regarding blockchain crowdsourcing. First, to design smart contracts with lower consumption to meet the needs of blockchain crowdsourcing services and also need to design better interaction modes to further reduce the cost of blockchain crowdsourcing services. Second, to design an effective privacy protection mechanism to protect user privacy while still providing high-quality crowdsourcing services for location-sensitive multiskilled mobile space crowdsourcing scenarios and blockchain exposure issues.

This paper proposes a blockchain-based privacy-preserving crowdsourcing model for multiskill mobile spaces. The model in this paper uses the zero-knowledge proof method to make the requester believe that the user is within a certain location without the user providing specific location information, thereby protecting the user’s location information and other privacy. In addition, through off-chain calculation and on-chain verification methods, gas consumption is also optimized.

This study deployed the model on Ethereum for testing. This study found that the privacy protection is feasible and the gas optimization is obvious.

This study designed a mobile space crowdsourcing based on a zero-knowledge proof privacy protection mechanism and optimized gas consumption.

This study aims to provide healthcare managers with a meaningful synthesis of state of the art knowledge on error proofing strategies. The purpose is to provide a foundation for understanding medical error prevention, to support the strategic deployment of error proofing strategies, and facilitate the development and implementation of new error proofing strategies.

A diverse panel of 40 healthcare professionals evaluated the 150 error proofing strategies presented in the AHRQ research monograph using classification systems developed by earlier researchers. Error proofing strategies were ranked based on effectiveness, cost, and ease of implementation as well as based on their aim/purpose, i.e. elimination, replacement, facilitation, detection, or mitigation of errors.

The findings of this study include prioritized lists of error proofing strategies from the AHRQ manual based on the preferred characteristics (i.e. effectiveness, cost, ease of implementation) and underlying principles (i.e. elimination, replacement, facilitation, detections mitigation of errors) associated with each strategy.

The results of this study should be considered in light of certain limitations. The sample size of 40 panelists from hospitals, medical practices, and other healthcare related companies in the Gulf Coast region of the USA prevents a stronger generalization of the findings to other groups or settings. Future studies that replicate this approach, but employ larger samples, are appropriate. Through the use of public forums and expanded sampling, it may be possible to further validate research findings in this paper and to expand and build on the results obtained in this study.

Using the error‐proofing strategies identified provides a starting point for researchers seeking to better understand the impact of error proofing on healthcare services, the quality of those services and the potential financial ramifications. Further, the results presented enhance the strategic deployment of error proofing strategies by bringing to light some of the important factors that healthcare managers should consider when implementing error proofing solutions. Most notably, healthcare managers are encouraged to implement effective solutions, rather than those that are merely inexpensive and/or easy to implement, which is more often the case.

This study provides a much‐needed forum for sharing error‐proofing strategies, their effectiveness, and their implementation.

The purpose of this study is to contribute to the literature on information elicitation. The authors investigated the impact of social influence strategies on eyewitness recall performance. Specifically, the authors examined the effect of social influence techniques (Cialdini, 2007) on recall performance (Experiment 1) and conducted a follow-up experiment to examine the incremental effect of social proof on the report everything cognitive interview mnemonic (Experiment 2).

Participants watched a video depicting vandalism (Experiment 1: N = 174) or a verbal altercation (Experiment 2: N = 128) and were asked to recall the witnessed event. Experiment 1: Participants were assigned randomly to one of six conditions: control (open-ended prompt), engage and explain (interview ground rules), consistency (signing an agreement to work diligently), reciprocity (given water and food), authority (told of interviewer’s training) and social proof (shown transcript from an exemplar participant). Experiment 2: The authors used a 2 (social proof: present, absent) × 2 (report everything: present, absent) between-participants design.

Across both experiments, participants exposed to the social proof tactic (i.e. compared to a model exemplar) spoke longer and recalled more correct details than participants not exposed to the social proof tactic. In Experiment 2, participants interviewed with the report everything mnemonic also spoke longer, recalled more correct details, more incorrect details and provided slightly more confabulations than those not interviewed with the report everything mnemonic.

The findings have practical value for police investigators and other professionals who conduct interviews (e.g. military personnel, doctors obtaining information from patients). Interviewers can incorporate social proof in their interviewing practices to help increase the amount and accuracy of information obtained.

The purpose of this paper is to examine how rural entrepreneurship is discussed by analyzing articles in the leading journals of the two main research fields, entrepreneurship studies, and rural studies, through the concept of rural proofing.

The systematic literature review centers on the two main fields where rural entrepreneurship is studied and covers papers in nine leading journals in entrepreneurship studies and two leading journals in rural studies, between the years 1989 and 2020. In total, 97 papers were reviewed and we utilize and operationalize the rural proofing concept based on Fahmy et al.'s (2004) 3 characteristics of rural: remoteness, accessibility, and rural locale and sense of place. The authors take stock of the dimensions of rural proofing addressed within each of the research fields to find similarities and differences; that is, if articles are rural proofed (or not) when discussing rural entrepreneurship.

The classification of articles across the three dimensions of rural proofing shows that the field of rural entrepreneurship is being addressed mainly in the dimensions of remoteness and accessibility, while few authors in rural studies journals give priority to the rural locale and sense of place dimension. The results of the authors' review reveal that out of a total of 97 articles on rural entrepreneurship, 56 articles address at least one dimension of rural proofing and 41 articles do not address any dimension. Among the 41 articles not rural proofed, rurality is not problematized when discussing rural entrepreneurship. Instead, the authors focus on specific topics such as social capital, community entrepreneurship/networks, entrepreneurs'/farmers' identity, illegality in rural areas, and institutional framework. The number of non-rural-proofed articles in entrepreneurship journals is almost double that in rural studies journals. This means that authors in entrepreneurship journals do not problematize rurality to the same extent as authors in rural studies journals when addressing rural entrepreneurship.

The authors emphasize the need for increased cross-fertilization between the fields of entrepreneurship and rural studies as an avenue to develop the entrepreneurship field in the direction towards rural proofing. A close collaboration with academia and policymakers is essential to promote interdisciplinary research in order to make a distinctive contribution to rural development. Scholars in either of the two fields will benefit from our review and identification of similarities and differences in the research. The review is one step towards promoting a closer dialog between the two fields.

Previous reviews have focused mainly on what rural entrepreneurship entails (e.g. what topics are discussed) rather than how rural entrepreneurship is discussed. This paper centers on the differences and similarities of the two main fields and provides an in-depth qualitative analysis of how rural entrepreneurship is discussed by utilizing the rural proofing concept.

Discusses the relationship between computer proof and human proof. These issues are discussed both in general and specifically regarding the recent solution of the Robbins problem via a proof generated by computer. The Robbins problem was a long‐standing open problem about axioms for Boolean algebra. One point of this paper is to show that the proof of the Robbins conjecture, generated by a computer, can be filled in and understood by human beings. We accomplish this aim in the present paper by presenting a notational reformulation of Boolean algebra and the Robbins problem. The notational/linguistic issue developed here is of cybernetic, linguistic and semiotic interest. It is our contention that mathematics can behave non‐trivially under change of notation. Change of notation can be as significant as change of language. In the present case the change of language afforded by an appropriate change of notation makes a mathematical domain accessible to human beings that has heretofore been only accessible to computers.

The World Trade Organization (WTO) is one of the best dispute settlement mechanisms in the world. Under WTO rules, aggrieved parties must establish a “prima facie” case before the panel can call on the offending party to respond to the claims. The objective of the present study is to critically evaluate the application of the concept of burden of proof under WTO dispute settlement mechanism.

The paper examines the rule of “prima facie” in WTO jurisprudence. To do so, the first part will focus on the development of dispute settlement within WTO. The second part is divided into several subsections that will focus on the burden of proof concept, burden of proof in common law, burden of proof in civil law and the prima facie standard.

The DSU does not explicitly regulate how to allocate the burden of proof, but panels and the AB needed to address that issue early in their history. Despite this, all aggrieved parties to establish a prima facie case before the case can become the subject of a panel hearing. There is a need to adopt a burden of proof standard that assesses evidence on the basis of preponderance of the available evidence rather than on the basis of a party’s failure to adduce evidence to back up or dispute a claim.

The paper is an attempt to address an important issue on the presentation of evidence and proof in international litigation, i.e. WTO.

In 2009, the Third Circuit decided Hydrogen Peroxide, which announced a more rigorous standard under Federal Rule of Civil Procedure 23(b)(3) for assessing whether a putative class could establish antitrust injury. Earlier this year, the Supreme Court decided Comcast v. Behrend, a case that carries potentially broad implications for both antitrust cases and Rule 23(b)(3) class actions generally. A review of the case law starting with Hydrogen Peroxide and continuing through Comcast and its progeny reveals the new rigor in antitrust class action decisions and suggests what the future may hold, including the type of arguments that may provide defendants the most likely chance of defeating class certification. After Comcast, rigor under 23(b)(3) can no longer be avoided in assessing all class actions questions, and courts should now apply Daubert fully in the class setting concerning both impact and damages. Courts should also closely evaluate plaintiffs’ proposed methodologies for proving impact to determine if they apply to each class member. Finally, courts will inevitably have to determine how rigorously to scrutinize experts’ damages methodologies and whether Comcast requires or suggests more scrutiny in assessing common evidence for measuring damages.

The present study provides a comprehensive review of the advancements in five active heating modes for cold-proof clothing as of 2021. It aims to evaluate the current state of research for each heating mode and identify their limitations. Further, the study provides insights into the optimization of intelligent temperature control algorithms and design considerations for intelligent cold-proof clothing.

This article presents a classification of active heating systems based on five different heating principles: electric heating system, solar heating system, phase-change material (PCM) heating system, chemical heating system and fluid/air heating system. The systems are analyzed and evaluated in terms of heating principle, research advancement, scientific challenges and application potential in the field of cold-proof clothing.

The rational utilization of active heating modes enhances the thermal efficiency of cold-proof clothing, resulting in enhanced cold-resistance and reduced volume and weight. Despite progress in the development of the five prevalent heating modes, particularly with regard to the improvement and advancement of heating materials, the current integration of heating systems with cold-proof clothing is limited to the torso and limbs, lacking consideration of the thermal physiological requirements of the human body. Additionally, the heating modes of each system tend to be uniform and lack differentiation to meet the varying cold protection needs of various body parts.

The effective application of multiple heating modes helps the human body to maintain a constant body temperature and thermal equilibrium in a cold environment. The research of heating mode is the basis for realizing the temperature control of cold-proof clothing and provides an effective guarantee for the future development of the intelligent algorithms for temperature control of non-uniform heating of body segments.

The integration of multiple heating modes ensures the maintenance of a constant body temperature and thermal balance for the wearer in cold environments. The research of heating modes forms the foundation for the temperature regulation of cold-proof clothing and lays the groundwork for the development of intelligent algorithms for non-uniform heating control of different body segments.

The present article systematically reviews five active heating modes suitable for use in cold-proof clothing and offers guidance for the selection of heating systems in future smart cold-proof clothing. Furthermore, the findings of this research provide a basis for future research on non-uniform heating modes that are aligned with the thermal physiological needs of the human body, thus contributing to the development of cold-proof clothing that is better suited to meet the thermal needs of the human body.

The existing technology adoption model (TAM) has ignored the importance of social proof of credibility such as risk, security and privacy. Also, this study aims to provide understanding how the issues of usability such as interactivity, compatibility and credibility can influence the mobile banking (MB) adoption of commercial and Islamic banks. This study has offered two theoretical models which may be helpful to understand the importance of social proof of credibility during MB adoption.

It is exploratory study therefore the researcher used triangulation of qualitative methods such as online banking app reviews, focused group and semi structured interviews are used to understand the behavior of customers toward MB adoption.

Consumers are actively involved to take recommendations from close sources, experts, customers and crowd opinion using interactive social media platforms (SMPs). The purpose to gather information is to save from usability, risk, security and privacy issues, especially when customers share their personal and financial information with the purpose to use MB. Results reveal that people with disabilities require MB app that has adjustable size, color, text and functions. The usability issues such as system design, response time, aesthetics, personalization, installation and service quality influenced the use of MB in Islamic banks.

Present study has offered social proof as TAM which highlights usefulness and credibility as important factors that can create social proof on SMPs. This study provides rich insights regarding what initiatives are required to resolve the issues of usability such as interactivity, compatibility and credibility that can influence the MB adoption of commercial and Islamic banks. Another major contribution of this study is to explore the issues of MB for people with disabilities and suggest how they can improve the service quality of MB for people with disabilities.

This study analyses and discusses the application and constitutionality of the general onus of proof provision (section 82 of the Income Tax Act 58 of 1962 [the “Act”]), the presumption in favour of the State when criminal sanctions are applied to an offending taxpayer (section 104(2) of the Act) and the mechanics for imposing administrative sanctions in terms of section 76(1)(b) of the Act. The conclusion reached is that the reverse onus presumption, as provided for in terms of section 104(2) of the Act, is unconstitutional. It is penal in nature and offends against the constitutional right of an accused to a fair trial (sections 35(3) of the Constitution of the Republic of South Africa Act, 108 of 1996 [the “Constitution”]). The section 36 limitation of rights clause of the Constitution does not save it. Section 76(1)(b) of the Act read in conjunction with the deeming provision of section 76(5) of the Act, is inextricably linked to the section 82 general reverse onus provision of the Act. Hence, when these three sections are applied together, they create a reverse onus that, prima facie, violates the right to just administrative action (section 33 of the Constitution). Regarding the general reverse onus burden as provided for in terms of section 82 of the Act, the conclusion reached is that it is reasonable and justifiable in an open and democratic society and can therefore be regarded as constitutional.
