The Paradox of Human Expertise: Why Experts Can Get It Wrong
Expertise is correctly, but one-sidedly, associated with special abilities and enhanced performance. The other side of expertise, however, is surreptitiously hidden. Along with expertise, performance may also be degraded, culminating in a lack of flexibility and error. Expertise is demystified by explaining the brain functions and cognitive architecture involved in being an expert. These information processing mechanisms, the very making of expertise, entail computational trade-offs that sometimes result in paradoxical functional degradation. For example, being an expert entails using schemas, selective attention, chunking information, automaticity, and more reliance on top-down information, all of which allow experts to perform quickly and efficiently; however, these very mechanisms restrict flexibility and control, may cause the experts to miss and ignore important information, introduce tunnel vision and bias, and can cause other effects that degrade performance. Such phenomena are apparent in a wide range of expert domains, from medical professionals and forensic examiners, to military fighter pilots and financial traders
An Exploratory Study of Patient Falls
Debate continues between the contribution of education level and clinical expertise in the nursing practice environment. Research suggests a link between Baccalaureate of Science in Nursing (BSN) nurses and positive patient outcomes such as lower mortality, decreased falls, and fewer medication errors. Purpose: To examine if there a negative correlation between patient falls and the level of nurse education at an urban hospital located in Midwest Illinois during the years 2010-2014? Methods: A retrospective crosssectional cohort analysis was conducted using data from the National Database of Nursing Quality Indicators (NDNQI) from the years 2010-2014. Sample: Inpatients aged â„ 18 years who experienced a unintentional sudden descent, with or without injury that resulted in the patient striking the floor or object and occurred on inpatient nursing units. Results: The regression model was constructed with annual patient falls as the dependent variable and formal education and a log transformed variable for percentage of certified nurses as the independent variables. The model overall is a good fit, F (2,22) = 9.014, p = .001, adj. R2 = .40. Conclusion: Annual patient falls will decrease by increasing the number of nurses with baccalaureate degrees and/or certifications from a professional nursing board-governing body
From Negative to Positive Algorithm Rights
We consider this issue here and suggest that the current calls for a negative right to be free from AI could very well transform over time into positive claims that demand the use of algorithmic tools by government officials. In Part I, we begin by sketching the current landscape surrounding the adoption of AI by government. That landscape is characterized by strong activist and scholarly voices expressing a pronounced aversion to the use of digital algorithmsâand taking a decidedly negative rights tone. In Part II, we show that, although aversion to complex technology might be understandable, that aversion is neither inevitable nor impossible to overcome. We offer several examples of advanced technologies and analytic techniques that in the past have emerged in the face of significant criticism, but which have come to be widely accepted. In fact, there now exists an affirmative expectationâeven at times a legal oneâthat government should use these technologies when making consequential decisions affecting peopleâs interests.
Given the possibility of legal and, more broadly, public insistence on the use of at least certain kinds of advanced technologies, we put forward in Part III a set of factors that may help lead eventually to widespread acceptance of algorithmic technologies similar to the acceptance of the technologies discussed in Part II. We suggest that a path forward exists that might build a general acceptance of the use of algorithmic tools by governmental entities, a path that would represent a shift from present-day calls for negative-rights protections against AI to eventual positive-rights expectations that good government practices routinely involve the use of AI.

From Negative to Positive Algorithm Rights
Artificial intelligence, or âAI,â is raising alarm bells. Advocates and scholars propose policies to constrain or even prohibit certain AI uses by governmental entities. These efforts to establish a negative right to be free from AI stem from an understandable motivation to protect the public from arbitrary, biased, or unjust applications of algorithms. This movement to enshrine protective rights follows a familiar pattern of suspicion that has accompanied the introduction of other technologies into governmental processes. Sometimes this initial suspicion of a new technology later transforms into widespread acceptance and even a demand for its use. In this paper, we show how three now-accepted technologiesâDNA analysis, breathalyzers, and radar speed detectorsâtraversed a path from initial resistance to a positive right that demands their use. We argue that current calls for a negative right to be free from digital algorithms may dissipate over time, with the public and the legal system eventually embracing, if not even demanding, the use of AI. Increased recognition that the human-based status quo itself leads to unacceptable errors and biases may contribute to this transformation. A negative rights approach, after all, may only hamper the development of technologies that could lead to improved governmental performance. If AI tools are allowed to mature and become more standardized, they may also be accompanied by greater reliance on qualified personnel, robust audits and assessments, and meaningful oversight. Such maturation in the use of AI tools may lead to demonstrable improvements over the status quo, which eventually might well justify assigning a positive right to their use in the performance of governmental tasks
Blockchain technology to improve supply chain management - a systematic literature review
This study followed the systematic literature review approach to analyse how blockchain
technology can improve supply chain management and to promote a future research agenda.
The search was carried out at Web of Science Core Collection between September 2019 and
February 2020 by using the keywords âblockchainâ AND âsupply chainâ OR âblockchainâ
AND âlogisticsâ in the title. In this review 127 studies were identified for screening and a final
sample of 67 studies met the inclusion criteria and were analysed to answer the research
questions. After examining the selected studies, our findings uncover a range of approaches
showing how blockchain can enhance the supply chain management and point out which sectors
are most likely to benefit from its implementation. This study contributes to the existing
literature by systematising the most relevant information on blockchain implementation in
supply chains. In addition, the findings of this study also provide managers and researchers with
insights about the likely consequences of blockchain adoption in various sectors. Although
there are already some literature reviews on blockchain technology in the supply chain
management, this is one of the first studies that brings together the main issues focused on the
consequences of blockchain adoption in the supply chain management.A gestão da cadeia de abastecimento estå a passar por um processo de digitalização das suas
operaçÔes justificada pela Quarta Revolução Industrial (IndĂșstria 4.0) que prevĂȘ a adoção de
novas tecnologias com o objetivo de reduzir custos operacionais, aumentar a eficiĂȘncia da
cadeia de abastecimento e agregar valor aos produtos e serviços. Ferramentas tecnológicas
como a internet das coisas (IoT), identificação por radiofrequĂȘncia (RFID) e Big Data, estĂŁo a
ser utilizadas na melhoria dos controlos de produção, compra, procura, na tomadas de decisÔes
dos gestores, entretanto, a recente tecnologia blockchain tem chamado atenção de
pesquisadores e especialistas devido ao seu potencial transformador nos negĂłcios e
principalmente na gestão da cadeia de abastecimento. Por este motivo, este estudo propÔe uma
revisĂŁo sistemĂĄtica de literatura com o objetivo de analisar como a tecnologia blockchain pode
melhorar a gestão da cadeia de abastecimento e propor uma agenda de investigação para o
futuro.
A pesquisa foi realizada na base de dados Web of Science Core Collection entre setembro de
2019 e fevereiro de 2020 usando as palavras-chave "blockchain" E "supply chain" OU
"blockchain" E "logistics" no tĂtulo. O critĂ©rio de seleção dos artigos considerou apenas estudos
revistos por pares, anais de conferĂȘncia e livros nos idiomas inglĂȘs, espanhol, francĂȘs e
portuguĂȘs. A seleção dos estudos ocorreu em duas etapas. Na primeira etapa, foram analisados
tĂtulos e resumos. Na segunda etapa, foi realizada a leitura integral dos estudos que nĂŁo foram
excluĂdos na primeira fase. Os critĂ©rios de exclusĂŁo foram: artigos de revisĂŁo de literatura,
relatórios, estudos focados em informaçÔes técnicas, estudos que enfatizaram outras
tecnologias (IoT, RFID), gestĂŁo financeira da cadeia de abastecimento e/ou estudos
relacionados com bitcoins. Os artigos que preencheram um desses critĂ©rios foram excluĂdos
com justificativa. Embora tenhamos excluĂdo artigos de revisĂŁo de literatura, esses documentos
ainda foram utilizados para identificar estudos-chave que nĂŁo haviam sido capturados da base
de dados Web of Science. Por fim, nesta revisĂŁo foram identificados 127 estudos para triagem
e uma amostra final de 67 estudos atendeu aos critérios de inclusão e foram analisados para
responder Ă s perguntas da pesquisa.
As perguntas a que a pesquisa teve por objetivo responder foram: quais os benefĂcios e riscos
da tecnologia blockchain; quais os setores que jĂĄ adotaram a tecnologia blockchain na gestĂŁo
da cadeia de abastecimento e sua fase de implementação; quais as caracterĂsticas das empresas que utilizam a tecnologia; quais sĂŁo os fatores facilitadores e barreiras para a adoção da
tecnologia blockchain nas empresas; qual a influĂȘncia da tecnologia blockchain na garantia da
sustentabilidade da cadeia de abastecimento dentro da estratĂ©gia organizacional e dos nĂveis
operacionais; como avaliar o desempenho da tecnologia blockchain na gestĂŁo da cadeia de
abastecimento.
Os estudos selecionados apontam que a partir de 2017 houve um aumento expressivo de estudos
relacionados ao uso da tecnologia blockchain na cadeia de abastecimento. Os Estados Unidos,
China e Ăndia sĂŁo os paĂses com a maior percentagem de publicaçÔes sobre o tema e representam
aproximadamente 44% do total. Os estudos foram publicados em jornais especializados em
sistema de produção e processos, engenharia industrial, tecnologia, gestĂŁo, logĂstica, cadeia de
abastecimento e sustentabilidade. Quanto aos benefĂcios e riscos da adoção da tecnologia
blockchain, os estudos indicam que a transparĂȘncia dos dados, rastreabilidade e a redução dos
custos operacionais sĂŁo um dos maiores benefĂcios da adoção da tecnologia blockchain na
cadeia de abastecimento, enquanto a escalabilidade e interoperabilidade foram identificados
com os maiores riscos/limitaçÔes da implantação da tecnologia. No que tange aos fatores
facilitadores da adoção da tecnologia blockchain, a gestão de topo apresenta-se como agente
principal no incentivo à adoção do blockchain nas organizaçÔes, além disso, a perceção de
utilização da tecnologia pelos funcionårios também influencia o sucesso de implantação da
tecnologia blockchain. Outras caracterĂsticas que afetam a adoção da tecnologia sĂŁo a
infraestrutura das empresas, polĂticas governamentais e a cultura do paĂs, entretanto esses
fatores tendem a ter nĂveis diferentes de acordo com o paĂs onde a empresa estĂĄ instalada. No
que diz respeito aos fatores que dificultam a implantação do blockchain nas organizaçÔes, são
apontados a falta de conhecimento da tecnologia blockchain e dos seus potenciais benefĂcios,
a existĂȘncia de um nĂșmero reduzido de aplicaçÔes do blockchain nas empresas, a coordenação
e comprometimento dos parceiros de negócios na resolução de problemas e no tratamento de
dados, fatores externos, como a legislação e incentivos governamentais.
Após examinar os estudos selecionados, a nossa anålise revela uma série de abordagens que
mostram como a blockchain pode melhorar a gestĂŁo da cadeia de abastecimento e identifica os
setores mais propensos a retirar benefĂcios de sua implementação. A indĂșstria de alimentos e a
indĂșstria farmacĂȘutica sĂŁo apontados como os setores com maior vantagem na adoção do
blockchain devido a criticidade dos seus produtos, a procura crescente por informaçÔes
referente a proveniĂȘncia dos bens e seu alto valor agregado. O perfil das organizaçÔes que adotaram a tecnologia blockchain sĂŁo geralmente multinacionais de grande e mĂ©dio porte, com
capilaridade de parceiros de negócios, grande volume de produção e alto valor agregado aos
seus bens. Quanto a sustentabilidade, a tecnologia blockchain pode influenciar, através da
transparĂȘncia e rastreabilidade dos produtos, na redução da produção de lixo e das emissĂ”es de
carbono no meio ambiente, no controlo das leis e prĂĄticas laborais, evitando-se trabalho escravo
e, relacionado com as questÔes económicas, redução dos custos com auditorias, controlo de
pedidos de compra, produção e procura. Os indicadores de performance, de acordo com os
estudos revistos, podem ser melhorados com a utilização da tecnologia blockchain,
promovendo novas mĂ©tricas sustentĂĄveis baseadas na rastreabilidade e na transparĂȘncia dos
dados. Apesar da fase inicial da tecnologia blockchain, alguns estudos propÔem indicadores
que avaliam a eficiĂȘncia da cadeia de abastecimento apĂłs a adoção do blockchain, como o
tempo de processamento das transaçÔes, a utilização de recursos (ĂĄgua, energia elĂ©trica) e nĂveis
de emissĂŁo de carbono.
Embora jå existam algumas revisÔes de literatura sobre a tecnologia blockchain na gestão da
cadeia de abastecimento, este Ă© um dos primeiros estudos que reĂșne questĂ”es importantes
focadas nas consequĂȘncias da adoção do blockchain na gestĂŁo. AlĂ©m disso, os resultados deste
estudo fornecem implicaçÔes para a gestĂŁo e para a teoria sobre as provĂĄveis consequĂȘncias da
adoção de blockchain em vårios setores da economia

Assessing the impact of e-learning on decision-making to reduce health risks: Perceptions from UCT's pesticide risk management cohort
Includes bibliographical referencesThere is a need to build the capacity of professionals in low- to middle- income countries (LMICs) in order to reduce pesticide risks on human and environmental health. To address these risks, the University of Cape Town (UCT) introduced the Post Graduate Diploma in Pesticide Risk Management (DPRM). This programme utilises a mixed teaching mode including an e-learning component which includes virtual seminars/discussion forums. The DPRMs' discussion forum aimed to strengthen skills in managing and reducing pesticide risks. Due to the shortage of skilled professionals in LMICs, e-learning can facilitate the on-going training and skills development in pesticide management to address pesticide related challenges. The study focus was on evaluating the impact of the DPRMs' e-learning Discussion Forum bi-monthly sessions on the decision-making processes of professionals in LMICs working in pesticide risk management. The sample for this study was obtained from a population of working professionals, who either completed or were currently enrolled for the DPRM programme (N=37). Twenty-two participants completed the online questionnaire anonymously. These participants were employed by governments, non-governmental organizations (NGOs), research institutes and private companies in Africa and Fiji. This mini-dissertation is divided into four parts. The protocol (Part A) provides the study justification and describes the methodology for collecting the data and the analysis thereof. The literature review (Part B) describes e-learning and how it relates to capacity building of pesticide risk management (PRM) professionals in LMICs countries. It looks at the challenges of implementing and maintaining successful capacity building and the role e-learning plays. The manuscript of a journal ready article (Part C) presents the research findings on the perceived effectiveness of the e-learning based DPRM discussion forum and whether it aided PRM professionals in making better decisions. There are four appendices (Part D) which include the questionnaire, consent form, ethical approval and instructions for writing the manuscript. The study found that participants reported improved application of information gained through e-learning in a practical and effective manner, thereby improving their skills for real world scenarios. Overall benefits acknowledged by participants included establishing a knowledge resource, improved communication with colleagues and stakeholders, as well as improved ability for knowledge application in their work and pesticide use in context. An important finding was that just over half of respondents (55%) felt that they were able to contribute to policy change in their countries as a result of the discussion forum. Unfortunately, no statistical significance could be established between variables due to the limited sample size. It is recommended that a follow-up study with a larger sample be conducted, to establish whether the discussion forum has a long-term and sustainable impact in decision- making processes and policy implementation
Technology management in the effective implementation of change
Organizational fitness is often achieved by making changes in business operations. These changes frequently involve the use of a new technology. The effective implementation of change is achieved by examining the benefits and challenges of technology management when making decisions. Important elements for consideration in technology management are technology evaluation, integration, planning, implementation, training, and change. A solution is proposed to combine and encompass all the elements of technology management to allow for the positive aspects and avoid the negative aspects of change implementation. The tool consists of principles to be addressed for each element
