La cuarta revolución industrial trae consigo muchos cambios en la forma y la diversidad en las que se desarrollan las actividades del mundo en general. La situación se vuelve bastante compleja en el caso de las personas graduadas universitarias, dado que esta revolución presenta retos con los nuevos conocimientos, habilidades y capacidades para desarrollar dentro de los puestos de trabajo, lo cual fomenta la aparición de grandes desafíos que involucran los procesos de la automatización. Con el objetivo de perfilar cada una de las disciplinas respecto a diferentes grupos de habilidades, la presente investigación se estructura en tres etapas metodológicas. La primera, es mediante la descripción de los perfiles académicos de las universidades estatales costarricenses, siendo este conjunto de documentos la población de estudio. La segunda, es sobre la construcción de un diccionario de palabras y la tercera, se trata de la construcción de la base de datos que alberga competencias y habilidades de las personas graduadas universitarias de cada una de las disciplinas. Todo lo anterior fue posible, mediante el desarrollo de una serie de herramientas programadas en el lenguaje Python, para la recolección de información, extracción de habilidades y competencias, y finalmente, el cálculo de las proporciones. El principal resultado de la investigación, es la construcción y naturalización de una base de datos a nivel de carreras universitarias estatales, mediante la creación de ocho grupos de habilidades y competencias debidamente integrados por competencias asociadas a diferentes temáticas. El aporte más importante, es el análisis integral de los perfiles académicos de las carreras universitarias.
La técnica de seguimiento ocular y el estudio de modelos tácitos mediante criterios subjetivos y conductuales
Authors: Díaz-Chang Tamara , Arredondo Elizabeth-H
Published: January 2022

En este artículo se presentan los resultados de una investigación de enfoque mixto, donde se examina el movimiento ocular del estudiantado de pregrado de la Universidad Austral de Chile, mientras se resuelve un cuestionario donde aparecen modelos tácitos, relacionados con el infinito matemático, con el objetivo de determinar posibles correlaciones entre los parámetros de la actividad ocular y el nivel de dificultad de cada uno de estos modelos. Las categorías del nivel de dificultad se establecieron con base en dos tipos de criterios: uno subjetivo, mediante una evaluación realizada por los sujetos y uno conductual, relacionado con la obtención de la solución correcta. Se identificaron las correlaciones de estos criterios con los parámetros de actividad ocular, que se consideraron indicadores de esfuerzo mental. El análisis de los datos obtenidos permitió observar discrepancias en la categorización de los modelos tácitos, con base en criterios subjetivos y conductuales. Hubo una correlación negativa de los parámetros del movimiento ocular con las opiniones de los estudiantes, sobre el nivel de dificultad de las preguntas, mientras que se notó una fuerte correlación positiva y significativa entre la presencia de estos modelos y el nivel de dificultad, determinado por el porcentaje de respuestas correctas. A su vez, el porcentaje de respuestas correctas tuvo una fuerte correlación positiva y significativa con la mayoría de los parámetros de la actividad ocular. A partir de estos resultados, se concluye que, estos parámetros pueden tomarse como un índice del nivel de dificultad de los modelos tácitos presentes en una actividad.
A forma do realismo: a crítica de Cyro Siqueira na Revista de Cinema
Authors: Turibio Thiago
Published: January 2022

O objetivo do artigo é analisar o método crítico de Cyro Siqueira na primeira fase da Revista de Cinema (1954-1957) de Minas Gerais. Em geral, a crítica de cinema no Brasil de 1950 é compreendida no campo acadêmico a partir de esquemas que a divide seja entre “esteticistas” e “crítico-históricos”, seja entre “universalistas” e “nacionalistas”. Nos perguntamos, assim, se os esquemas, sobretudo o primeiro, contribuem para a compreensão da escrita de Cyro Siqueira. A pesquisa nos permite concluir que não. Cyro Siqueira foi um crítico realista, interessado em problemas de conteúdo, como a crítica comunista da época. No entanto, ao contrário desses últimos, reservou lugar central em seu método para a análise formal. Sendo assim, a escrita de Cyro coloca em crise os esquemas binários ainda dominantes na análise acadêmica da crítica dos anos 1950. Em termos de método, mobilizamos alguns pressupostos dos estudos de recepção, tais como os apresentou Janet Staiger. Dessa forma, buscamos analisar os princípios gerais, históricos e compartilháveis, implícitos no método praticado por Cyro. Além disso, nos valemos do conceito de campo de Pierre Bourdieu com o fim de descrever as divisões dominantes entre a crítica da época.

Festivais de cinema e georreferenciamento: um estudo sobre o território ocupado pela Mostra Internacional de Cinema de São Paulo em seus primeiros anos
Authors: Dylan Emerson , Ferla Luis
Published: January 2022

A Mostra Internacional de Cinema de São Paulo é um dos principais festivais cinematográficos do país. Criada em 1977 por Leon Cakoff, a Mostra nasceu junto ao Museu de Arte de São Paulo (MASP) e esteve vinculada à instituição durante seus primeiros sete anos. Neste período, a Mostra se expandiu, passando a ocupar outras salas de cinema na cidade de São Paulo. Neste artigo, será apresentado um breve percurso histórico da Mostra desde o seu surgimento até a primeira edição organizada independentemente do MASP, em 1984. Será analisada a sua inserção na capital paulista a partir de georreferenciamento dos espaços ocupados por ela em seus oito primeiros anos, utilizando como ferramenta o Sistema de Informações Geográficas (SIG). Mesclando uma análise histórica e espacial, tenciona-se compreender como o festival de Cakoff se constituiu enquanto um dos principais territórios da sociabilidade cinéfila na capital paulista e que, por conseguinte, conquistou uma notória longevidade e legitimidade.

Authors: Zanatto Rafael Morato
Published: January 2022

A realização do Festival de Cinema Científico Educativo como parte da programação do I Festival Internacional de Cinema do Brasil (1954) foi um evento importante para o desenvolvimento do cinema científico brasileiro em termos técnicos, artísticos e institucionais. Contando com a presença de Jean Painlevé e com o empréstimo de filmes da Associação Internacional de Cinema Científico, o festival movimentou o cenário científico e cultural brasileiro suscitando importantes discussões sobre a natureza desse cinema, seus objetivos, técnicas, critérios e temas. Exibindo lado a lado os cinemas europeu e brasileiro, o festival liga o Brasil ao fenômeno dos festivais que floresce após o fim da II Guerra mundial na Europa e dos quais o cinema científico é partícipe. Em linhas gerais, a significação local do festival foi imensa, tanto pelos programas que exibiu quanto pela reflexão que suscitou a propósito do passado, do presente e também do futuro do cinema científico no Brasil.
A Modernidade Contra as Lágrimas: O Melodrama e o Nuevo Cine Latinoamericano
Authors: Marques Henrique Rodrigues , Gomes Terao David Ken
Published: January 2022

Apresentando um projeto de superação do velho cinema da América Latina, os cineastas do Nuevo Cine Latinoamericano, teorizaram propostas de “novidade” dentro da modernidade cinematográfica, almejando a construção de uma estética revolucionária transnacional. Em seus textos, alguns autores manifestam clara recusa ao melodrama, gênero narrativo de maior sucesso de público no continente e que formou a linguagem cinematográfica dos cinemas nacionais por décadas, mas que foi entendido por esses nomes combativos como reflexo de uma ideologia burguesa conformista. No entanto, essa recusa não se deu sem contradição e o desejo de eliminar o melodrama das filmografias latino-americanas lançadas a partir da década de 1960 não se concretizou e o gênero seguiu sendo reapropriado até os dias de hoje, sendo inclusive encontrado na obra de cineastas deste mesmo grupo. O presente artigo analisará essas oposições ao melodrama, bem como suas contradições, a partir da Teoria dos Cineastas do Nuevo Cine Latinoamericano e de textos que analisam os usos do gênero antes e depois desse período.

Published: January 2022

Background: Coronary artery bypass grafting (CABG) is a
surgical procedure used in the treatment of coronary artery disease and
to improve heart function. Right ventricular (RV) function is unclear
based on myocardial velocities before and after coronary artery bypass
graft surgery. RV dysfunction is a known cause of hypotension in early
CABG surgery. The diastolic function has been shown to be a significant
contributor to mortality and cardiac morbidity in recent years. Our
study aimed to assess RV diastolic dysfunction after CABG surgery.
Methods: Forty-four patients with the two-vessel disease (2
VD), small vessel disease (SVD) and three-vessel disease (3 VD) facial
ischemia candidates for CABG surgery were studied. All patients
underwent colour Doppler and RV strain echocardiography before and one
month after CABG surgery, and patients’ RV function indices were
calculated. Data analysis was performed using SPSS 21 software and a
value of P<0.05 was considered statistically significant.
Results: Out of forty patients, the male to female ratio was
32:8 and their mean age was 65.17 ± 7.87 years and their mean body mass
index was 25.59± 3.20. Four patients were operated on without pumps. One
month after CABG, systolic pulmonary artery pressure (SPAP), left
ventricular ejection fraction (LVEF) and RV Diameter indexes increased
significantly. Fractional area change (FAC), RV global longitudinal
strain (GLS), Tissue Doppler imaging systolic wave (SM), RV myocardial
perfusion imaging (MPI) and Tricuspid annular plane systolic excursion
(TAPSE) decreased, which was less in the 3VD group than in the 1VD/2VD
group (P <0.001). There was no significant difference between
RV diastolic diameter (RVDD) and left ventricular diastolic diameter
(LVDD) before and one month after CABG (P <0.05).
Additionally, no significant correlation was detected between changes in
RV strain and pump connection time. Conclusion: RV diastolic
function is significantly reduced after CABG surgery. Surgery without
the pump can certainly not eliminate this dysfunction and be effective
in reducing its severity.

The conservation of aquatic flora and fauna and the protection of the aquatic biota in recent times has become a great challenge to fish biologists and limnologists. The location of most estuaries in connection with their linkages with freshwater and the marine environment make them to be heavily impacted with anthropogenic activities. However, information on the present state of physico – chemical parameters of Okerenkoko Estuarine are scarce. Therefore, the dynamics of physico – chemical parameters of Okerenkoko Estuarine, Delta State, Nigeria were studied. Okerenkoko Estuarine (62.79 Km) was spatially stratified into five stations (Z1, Z2, Z3, Z4 and Z5) based on closeness to major anthropogenic activities. Three sampling points were randomly selected from each station. Temporal stratification covered June to December. Water samples were collected from each station monthly for 7 months following standard methods. Water samples were analysed for Temperature (oC), Dissolved Oxygen (DO, mg.L-1) and Total Suspended Solids (TSS, mg.L-1) by using standard procedures. Data were analysed by using descriptive statistics and ANOVA at α0.05. Spatially, the highest (31.86±2.12) oC and least (24.45±1.67) oC Temperature were obtained in Z5 and Z1; DO (6.45±0.26, 3.97±0.24) mg.L-1 occurred in Z2 and Z3; TSS (70.17±3.90, 41.54±1.70) mg.L-1 were recorded in Z4 and Z2, respectively. Temporally, Temperature ranged from 24.70±5.13 oC in July to 31.50±4.87 oC in December; DO (3.85±0.43, 5.70±0.45) mg.L-1 in September and June; TSS (25.32±0.90, 75.05±0.64) mg.L-1 in December and September, respectively. The patterns of physico – chemical parameters of Okerenkoko Estuarine are highly unstable with TSS. Thus, its rich fauna biodiversity could be threatened.

Hyperhidrosis is a dermatological condition that causes psychosocial impairment and has a negative impact on patients’ quality of life. The epidemiology of hyperhidrosis is currently poorly understood. The aim of this study was to analyse comorbidities and treatments in 511 subjects with hyperhidrosis selected from the patient records of Oulu University Hospital. The mean age of patients with local hyperhidrosis was 27.9 years and the majority were female (62.7%). The most common anatomical site of symptoms in the youngest age group was the palms, whereas the axillae were a more common site in advanced age. Depression was a common comorbidity in both local (11.6%) and generalized hyperhidrosis (28.6%). Anxiety affected 12.7% of patients with generalized hyperhidrosis. In 36.8% of the patients with local hyperhidrosis there was a delay in diagnosis of more than 10 years. The most commonly used treatments included topical antiperspirants, iontophoresis and botulin toxin injections.

Published: January 2022

Apresenta-se pesquisa teórico-empírica que objetivou compreender as singularidades do raciocínio lógico matemático em estudos já publicados e posteriormente em dez alunos altamente habilidosos com idades entre 11 e 14 anos, a partir da epistemologia genética e método clínico piagetiano e com proposição de situação problema utilizando o jogo CONTIG 60. Por meio de análise qualitativa pôde-se verificar escassez de trabalhos para fundamentar a prática docente, assim como constatou-se que os alunos apresentaram desempenho superior aos da sua idade, sendo que as estratégias cognitivas utilizadas quando em jogo foram diferentes. Para resolução de problemas os jovens demonstraram necessidade de mais tempo para concentração diante da atividade proposta e outros ainda, usaram a criatividade para chegarem a um resultado que julgaram correto. A resolução de problemas silogísticos e matemáticos se demonstrou eficiente na compreensão e desenvolvimento das habilidades cognitivas e as situações em que tais habilidades surgem, assim, conclui-se que há significativa importância em os professores da matemática conhecerem conceitos básicos de desenvolvimento infantil, silogismo matemático e raciocínio lógico na orientação de sua prática docente.

Neste artigo são apresentados resultados parciais de uma pesquisa realizada com estudantes de um curso de Licenciatura em Matemática, com o objetivo de investigar as contribuições do Design ou de Problemas e da metodologia de Resolução de Problemas para a construção de conhecimentos matemáticos para o ensino do conteúdo de Progressões Aritméticas e Geométricas. Foram propostos aos participantes da pesquisa dez problemas sobre o conteúdo e aplicados de modo remoto. Os dados foram obtidos por meio das respostas escritas das atividades realizadas pelos alunos e das gravações das conversas realizadas por meio de vídeo conferências. Concluiu-se que apesar dos licenciandos apresentarem bons resultados no que diz respeito à metodologia de Resolução de Problemas, eles estão pouco familiarizados com a reformulação ou redesign de problemas, pois em suas respostas apareceram poucas modificações nos enunciados propostos. Em relação à construção de conhecimentos matemáticos para o ensino referentes às Progressões Aritméticas e Geométricas, constatou-se que há indícios da construção de tais conhecimentos pelos licenciandos, embora a maioria das resoluções ainda sejam baseadas em aplicações de fórmulas.
Narrativas de Professoras da Educação Infantil sobre o Ensino de Matemática para Crianças Pequenas
Authors: Ferreira Moura Jonata , Nacarato Adair Mendes
Published: January 2022

Este artigo objetiva problematizar os modos como seis professoras da Educação Infantil da rede municipal de ensino de uma cidade do oeste maranhense concebem o ensino de Matemática para crianças dessa etapa da educação brasileira. A pesquisa teve caráter biográfico. Sua principal fonte de documentação foi a entrevista narrativa, analisada a partir da proposta de Fritz Schütze. Pelas narrativas orais das docentes, há indícios de que a Educação Infantil não é lugar de escolarização, mas sim uma etapa de socialização. Assim, dispensa-se pouco tempo ao ensino de espaço e forma, grandezas e medidas, e Estocástica. As docentes entrevistadas realizam práticas que se aproximam daquilo que as pesquisas têm apontado como interessante; no entanto, essas ações são desenvolvidas pela intuição, pela imitação, e são naturalizadas sem que haja um processo reflexivo de sua eficácia. Há indícios, ainda, de que as docentes têm vontade de aprender e não medem esforços para realizar um trabalho de qualidade. Contudo, faltam-lhes apoio e formação permanente que atendam a suas necessidades.

Authors: Krakovsky Yuri , Gulyaev Aleksandr
Published: January 2022

Algorithmic and software support for probabilistic break-even analysis based on the Monte Carlo method has been developed to assess the predicted values of indicators of the efficiency of agricultural production, using the example of milk production in the Irkutsk region. The initial data for calculating the efficiency indicators are the following: fixed costs; variable costs per unit of output; average unit price; milk production; the amount of subsidies. To assess the efficiency of milk production, the following performance indicators are selected: operating profit, profitability of subsidies, payback period of subsidies. The functionality of the created software is described. The software helps test the models of the initial data, display the test results on the interface, as well as in visualized form, using graphs and histograms to display. Based on the developed software there have been obtained the point and interval estimates of the listed efficiency indicators. A check of the compliance of the forecast value of operating profit with the real value of this profit in 2020 was carried out. There has been stated a relevance of these values, the real value fell into the confidence interval defined during the simulation. The functionality of the created software made it possible to assess with high accuracy the predicted values of milk production efficiency indicators. In the future, the software can be upgraded by supplementing it with other probabilistic models of the initial data, as well as by expanding the modeled efficiency indicators, which will allow for a more detailed assessment of the predicted values of efficiency indicators including other types of agricultural products.

A political ecology of aviation and development: an analysis of relations of power and justice in the (de)construction of Nepal's Second International Airport
Authors: Geschewski Hanna , Islar Mine
Published: January 2022

In this article, we investigate socio-ecological conflicts surrounding the proposed Second International Airport project near Nijgadh, a town in the southern Terai region of Nepal. Praised by the Nepali government as a gamechanger for Nepal's economy, it has come under scrutiny by environmental activists after plans emerged for extensive clearing of the densely forested project site. While public and political debates have focused on the environmental impacts of the project, the area is also home to nearly 8,000 people, most of whom have no formal land rights and belong to Janajati groups, who face displacement. The apparent lack of attention to the project's consequences for local communities raises questions about the safeguarding of their interests. Drawing on justice theories and political ecology, we conducted a case study to investigate the residents' struggle for justice, recognition, and visibility amidst a strong dichotomy of mainstream developmentalist and conservationist discourses. During two months of fieldwork in Nepal, we gathered empirical evidence, including observations, interviews, and project documentation. Our findings suggest that the misrecognition of local communities, particularly in Tangiya Basti, began long before the airport project, and is intertwined with distributive and procedural injustices, reinforced by power asymmetries of various kinds. Overall, we argue that while the airport project is often framed as an environmental conflict, it is also a conflict over claims to social justice and livelihood security.

OBJECTIVE

To evaluate the effects of using an internal fixation plate to augment primary 3-loop pulley (3LP) repair of canine gastrocnemius tendons (GTs).

SAMPLE

48 cadaveric GTs from 24 adult dogs.

PROCEDURES

GTs were dissected free from other tissues, transected, and randomly assigned to 4 groups (n = 12/group). GTs were repaired with 2-0 polypropylene with a 3LP repair alone or a 3LP repair augmented with a 3-hole veterinary cuttable plate (3VCP), a 5-hole veterinary cuttable plate (5VCP), or a 7-hole veterinary cuttable plate (7VC P). Biomechanical loads, construct stiffness, gap formation, and failure modes were compared between groups.

RESULTS

Yield, peak, and failure loads were all significantly increased for the 5VCP and 7VCP groups, compared with the 3LP alone group. Increasing plate length from 3VCP to 5VCP and from 3VCP to 7VCP increased yield, peak, and failure loads. No differences were found between the 3LP and 3VCP groups with regard to yield and peak loads, but failure load was increased in the 3VCP group. Loads to create 1-mm and 3-mm gaps were significantly greater for the 5VCP and 7VCP groups, compared with the 3LP alone and 3VCP groups. Mode of plate attachment failure differed among groups.

CLINICAL RELEVANCE

Tendon plate augmentation may be a viable surgical option to increase the strength of the tenorrhaphy in dogs. However, in vivo studies evaluating the effects of plate augmentation on the tendon blood supply and progression of healing are needed prior to clinical application.

OBJECTIVE

To compare single and triplicate applanation tonometry values across previous intraocular pressure (IOP) studies in dogs.

ANIMALS

116 ophthalmologically normal dogs.

PROCEDURES

Triplicate IOP readings (n = 1432) from studies evaluating effect of anesthetic protocols were analyzed to estimate a range of probable differences between averaged triplicate and first, averaged and lowest, and first and lowest IOPs. The decrease in variability with triplicate measurements and the magnitude of effects on statistical power were quantified.

RESULTS

The 2.5th to 97.5th interpercentile range for differences of averaged triplicate values minus first IOP readings was –3 to 2.7 mm Hg; for averaged minus lowest: 0 to 3.7 mm Hg; for first minus lowest: 0 to 5 mm Hg. The 95% prediction interval for differences in study group means (n = 160 groups, n = 5 to 11 eyes per group) based on averaged minus first measurements was –1.0 to 0.9 mm Hg with associated SDs reduced by 4% on average. Analysis of previous studies using averaged instead of first IOP values resulted in minimal decreases in SEs of 3–9% (0.03 to 0.09 mm Hg). Of 11 comparisons found significant with averaged data, 2 (18%) were found nonsignificant with first measurements. Of 96 comparisons found nonsignificant with averaged data, 3 (3%) were found significant with first measurements.

CLINICAL RELEVANCE

With applanation tonometry in ophthalmologically normal dogs, no clinically meaningful difference was found between the first, lowest, or averaged triplicate IOP measurements, but the first reading has a larger variance and hence will result in lower statistical power.

Models for estimating the probability of default are widely used in the business throughout the lending process, starting as early as the application stage, where they play an important role in loan approval status. For model soundness and performance, ensuring adequate data quality is essential. Identifying outliers, analyzing their impact and choosing the right method to treat them is a necessary stage of preprocessing, which is often overlooked in practice for a variety of reasons, an important one being insufficient data. Given the inherent imbalance of the loan portfolio with regard to default status, elimination of outliers is seldom feasible. The current widely accepted approach is based on binning and weight of evidence. Usually two types of binning are tested, namely bucket and quantile. While the latter is robust to outlier presence, the former is not. Both approaches lead to the discretization of the continuous variable they are applied on. This causes information loss both in terms of variation given by individual values and in terms of distance between the various observation points on a certain variable. In the present paper, we explore the opportunity of using other methods for dealing with outlier presence and we describe their advantages and disadvantages in the context of probability of default estimation for credit risk. We conclude that, aside from quantile binning, not dealing with outliers in case of very large datasets or winsorizing are also effective. More importantly, several methods should be considered and tested for each variable in order to find the optimal balance between altering the data and reducing variance.
The impact of Tesla’s bitcoin investment and its plans to accept it as payment method on the evolution of bitcoin

For the past years, cryptocurrencies have been a hot and controversial topic that has captured the attention of the whole tech world. Even if right now the portfolio of digital assets is considerable in size, the first cryptocurrency, Bitcoin, exploited its pioneer advantage and managed to remain at the center of attention both for the media and investors.

During 2020, one of the most chaotic years, Bitcoin boomed in November 2020 almost doubling since the end of 2019. This boom is the result of a combination of factors, such as the fear of missing out translated into a chain reaction of public and private companies to consider Bitcoin a safe reserve asset, a hedging method against inflation, which represents a substitute for traditional hedging instruments, the infrastructure developed around it over the years, and lastly the hype created by influential figures through news and social media platforms. There have been many public figures that exhibited interest in cryptocurrencies through platforms such as Twitter, for instance Elon Musk, Bill Gates, Kanye West, Hugh Laurie, Mike Tyson and Gwyneth Paltrow are just some in a long list of celebrities that backed Bitcoin.

This paper aims to analyze the impact that twitter posts have upon the evolution of Bitcoin, coupled with Tesla’s investment and recent statement of introducing Bitcoin as a method of payment in the near future. Our research tries to determine if the news and social media posts, such as tweets have an influence upon Bitcoin’s volatility and fluctuations.
Key issues of tranzition to digital entrepreneurship
Authors: Bejinaru Ruxandra
Published: January 2022

Through this paper we want to contribute to the understanding of the main concepts, methods and tools which make possible the transition to a new type of entrepreneurship, namely digital entrepreneurship (DE). The importance of the topical concept, which is an accelerated expanding practice, lies in the fact that a digital business offers opportunities that transcend geographic space, primarily through global online space. The forecasts given to digital entrepreneurship are positive and even aspirational as they anticipate important benefits for the businesses that will create, sell and deliver digitally supported products and services. For the time being, what is presented in the specialized literature are reserved approaches towards the definitions, methodologies or strategies applicable to this type of entrepreneurship, which is in different phases of development on the globe. This research is done according to a simple scheme and we consider it logical in order to understand the transition of entrepreneurship from the knowledge-based economy to digital entrepreneurship. In this approach we proceeded first of all to document the main notions such as: the digitization process and the digitalization phenomenon; the specifics of business in the digital age; digital traction indicators for measuring business success in the digital environment; distinctive features of digital entrepreneurship and we ended with an integrative perspective, formulating recommendations for a successful transition to digital entrepreneurship. We believe that the contribution of this paper is to put together in a clear but concise manner, key aspects that highlight the transition of the traditional business vision to the vision proposed (or actually imposed) by digital entrepreneurship and the era in which we live.
From knowledge workers to knowmads: skills, roles and attributes – A literature review
Authors: Iliescu Andra Nicoleta
Published: January 2022

This paper aims to achieve a comprehensive image of the knowmad worker. Over the past few decades, knowledge workers have been at the center of academic and practical interest in the knowledge management field. Without excluding other management directions, this specific segment developed for a better understanding and sustaining of organizational knowledge dynamics. Recently - associated with unpredictable changes in all aspects of our lives, that have a direct impact on the business market - the knowmad typology gained increasingly more interest in the academic field, being recognized as an emergent group of learners and workers. They are associated with better adapting skills, increased innovation and creativity performances compared to previous knowledge workers and these qualities ensure individual and organizational competitivity in the contemporary society, as this paper will show. While the primary focus of existing knowmad literature is on the education shift towards a competence-based approach, the working coordinates of these workers remain in a secondary position in the existing literature. Through extensive literature review, and by using a data analysis engine, key concepts have been identified and analyzed in a systematic comparison between knowmads and knowledge workers. The first part of this paper is focused on placing the knowmad workforce into the relevant social context. In the second part and third part, the knowledge worker and knowmad typologies are analyzed from skills, roles, and attributes perspective. Findings obtained through this research show that the knowmad workforce represents the unavoidable future worker, which is both a consequence and a solution for a business environment defined by continuous unpredictable changes. In this respect, future research directions should be focused on the management of knowmad workforce.
