Published: April 2020

This research was motivated by the students’ low high order thinking skill which was related to teachers’ low competence in constructing high order thinking skills instrument. This study was intended to describe economics teachers’ competence and difficulties in developing instruments to measure higher order thinking skills. The subjects of this study were 45 economics teachers and 270 students from 27 public high schools in Bandung. The study employed quantitative survey method with questionnaire and focus group discussion (FGD) as the instruments.  The survey method was carried out to describe the teachers’ competences and difficulties in constructing instruments. The results of the study indicated that the teacher's competence in constructing high order thinking skills instruments was low. The research findings showed that only 12% of the teacher-made questions can be categorized at the analyzing level to creating level, and 88% were categorized in remembering to applying level. This resulted in the teachers’ obstacles in constructing higher order thinking skills instruments. The research findings signified that 80% of the teachers faced difficulties in constructing essay and multiple choices instruments.
Classification of Health-Related Social Media Posts: Evaluation of Post Content–Classifier Models and Analysis of User Demographics (Preprint)
Authors: Rivas Ryan , Sadah Shouq A , Guo Yuhang , Hristidis Vagelis
Published: April 2020

BACKGROUND

The increasing volume of health-related social media activity, where users connect, collaborate, and engage, has increased the significance of analyzing how people use health-related social media.

OBJECTIVE

The aim of this study was to classify the content (eg, posts that share experiences and seek support) of users who write health-related social media posts and study the effect of user demographics on post content.

METHODS

We analyzed two different types of health-related social media: (1) health-related online forums—WebMD and DailyStrength—and (2) general online social networks—Twitter and Google+. We identified several categories of post content and built classifiers to automatically detect these categories. These classifiers were used to study the distribution of categories for various demographic groups.

RESULTS

We achieved an accuracy of at least 84% and a balanced accuracy of at least 0.81 for half of the post content categories in our experiments. In addition, 70.04% (4741/6769) of posts by male WebMD users asked for advice, and male users’ WebMD posts were more likely to ask for medical advice than female users’ posts. The majority of posts on DailyStrength shared experiences, regardless of the gender, age group, or location of their authors. Furthermore, health-related posts on Twitter and Google+ were used to share experiences less frequently than posts on WebMD and DailyStrength.

CONCLUSIONS

We studied and analyzed the content of health-related social media posts. Our results can guide health advocates and researchers to better target patient populations based on the application type. Given a research question or an outreach goal, our results can be used to choose the best online forums to answer the question or disseminate a message.

Authors: Roka Zeinab Gura , Oyugi Elvis Omondi , Githuku Jane Njoki , Kanyina Evalyne , Obonyo Mark , Omballa Victor , Boru Waqo Gufu , Ransom James
Published: April 2020

BACKGROUND

In 2014, Kenya’s Field Epidemiology and Laboratory Training Program (FELTP) initiated a 3-month field-based frontline training, Field Epidemiology Training Program (FETP-F), for local public health workers.

OBJECTIVE

This study aimed to measure the effect of FETP-F on participant workplace practices regarding quality and consistency of public health data, critical interaction with public health data, and improvements in on-time reporting (OTR).

METHODS

Between February and April 2017, FELTP conducted a mixed methods evaluation via online survey to examine outcomes achieved among all 215 graduates from 2014 and 2015. Data quality assessment (DQA) and data consistency assessment (DCA) scores, OTR percentages, and ratings of the training experience were the quantitative measures tracked from baseline and then at 6-month intervals up to 18 months postcompletion of the training. The qualitative component consisted of semistructured face-to-face interviews and observations. Quantitative data were analyzed using descriptive statistics and one-way analysis of variance (ANOVA). Qualitative data were transcribed and analyzed to identify key themes and dimensions.

RESULTS

In total, 103 (47%) graduates responded to the survey. Quantitative analyses showed that the training significantly increased the mean DQA and OTR scores but there was a nonsignificant increase in mean DCA scores. Qualitative analyses found that 68% of respondents acquired new skills, 83% applied those skills to their day-to-day work, and 91% improved work methods.

CONCLUSIONS

FETP-F improved overall data quality and OTR at the agency level but had minimal impact on data consistency between local, county, and national public health agencies. Participants reported that they acquired practical skills that improved data collation and analysis and OTR.
Decision Support Capabilities of Telemedicine in Emergency Prehospital Care: Systematic Review (Preprint)
Authors: Kim Yesul , Groombridge Christopher , Romero Lorena , Clare Steven , Fitzgerald Mark Christopher
Published: April 2020

BACKGROUND

Telemedicine offers a unique opportunity to improve coordination and administration for urgent patient care remotely. In an emergency setting, it has been used to support first responders by providing telephone or video consultation with specialists at hospitals and through the exchange of prehospital patient information. This technological solution is evolving rapidly, yet there is a concern that it is being implemented without a demonstrated clinical need and effectiveness as well as without a thorough economic evaluation.

OBJECTIVE

Our objective is to systematically review whether the clinical outcomes achieved, as reported in the literature, favor telemedicine decision support for medical interventions during prehospital care.

METHODS

This systematic review included peer-reviewed journal articles. Searches of 7 databases and relevant reviews were conducted. Eligibility criteria consisted of studies that covered telemedicine as data- and information-sharing and two-way teleconsultation platforms, with the objective of supporting medical decisions (eg, diagnosis, treatment, and receiving hospital decision) in a prehospital emergency setting. Simulation studies and studies that included pediatric populations were excluded. The procedures in this review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. The Risk Of Bias In Non-randomised Studies–of Interventions (ROBINS-I) tool was used for the assessment of risk of bias. The results were synthesized based on predefined aspects of medical decisions that are made in a prehospital setting, which include diagnostic decision support, receiving facility decisions, and medical directions for treatment. All data extractions were done by at least two reviewers independently.

RESULTS

Out of 42 full-text reviews, 7 were found eligible. Diagnostic support and medical direction and decision for treatments were often reported. A key finding of this review was the high agreement between prehospital diagnoses via telemedicine and final in-hospital diagnoses, as supported by quantitative evidence. However, a majority of the articles described the clinical value of having access to remote experts without robust quantitative data. Most telemedicine solutions were evaluated within a feasibility or short-term preliminary study. In general, the results were positive for telemedicine use; however, biases, due to preintervention confounding factors and a lack of documentation on quality assurance and protocol for telemedicine activation, make it difficult to determine the direct effect on patient outcomes.

CONCLUSIONS

The information-sharing capacity of telemedicine enables access to remote experts to support medical decision making on scene or in prolonged field care. The influence of human and technology factors on patient care is poorly understood and documented.
Top Concerns of Tweeters During the COVID-19 Pandemic: Infoveillance Study (Preprint)
Authors: Abd-Alrazaq Alaa , Alhuwail Dari , Househ Mowafa , Hamdi Mounir , Shah Zubair
Published: April 2020

BACKGROUND

The recent coronavirus disease (COVID-19) pandemic is taking a toll on the world’s health care infrastructure as well as the social, economic, and psychological well-being of humanity. Individuals, organizations, and governments are using social media to communicate with each other on a number of issues relating to the COVID-19 pandemic. Not much is known about the topics being shared on social media platforms relating to COVID-19. Analyzing such information can help policy makers and health care organizations assess the needs of their stakeholders and address them appropriately.

OBJECTIVE

This study aims to identify the main topics posted by Twitter users related to the COVID-19 pandemic.

METHODS

Leveraging a set of tools (Twitter’s search application programming interface (API), Tweepy Python library, and PostgreSQL database) and using a set of predefined search terms (“corona,” “2019-nCov,” and “COVID-19”), we extracted the text and metadata (number of likes and retweets, and user profile information including the number of followers) of public English language tweets from February 2, 2020, to March 15, 2020. We analyzed the collected tweets using word frequencies of single (unigrams) and double words (bigrams). We leveraged latent Dirichlet allocation for topic modeling to identify topics discussed in the tweets. We also performed sentiment analysis and extracted the mean number of retweets, likes, and followers for each topic and calculated the interaction rate per topic.

RESULTS

Out of approximately 2.8 million tweets included, 167,073 unique tweets from 160,829 unique users met the inclusion criteria. Our analysis identified 12 topics, which were grouped into four main themes: origin of the virus; its sources; its impact on people, countries, and the economy; and ways of mitigating the risk of infection. The mean sentiment was positive for 10 topics and negative for 2 topics (deaths caused by COVID-19 and increased racism). The mean for tweet topics of account followers ranged from 2722 (increased racism) to 13,413 (economic losses). The highest mean of likes for the tweets was 15.4 (economic loss), while the lowest was 3.94 (travel bans and warnings).

CONCLUSIONS

Public health crisis response activities on the ground and online are becoming increasingly simultaneous and intertwined. Social media provides an opportunity to directly communicate health information to the public. Health systems should work on building national and international disease detection and surveillance systems through monitoring social media. There is also a need for a more proactive and agile public health presence on social media to combat the spread of fake news.

Authors: SAHIN SELMIHAN , DEMIR YASEMİN , OZMEN ISMAIL
Published: April 2020

Objective: In the present work, protease was produced from Bacillus subtilis under solid-state fermentation (SSF). The effect of lyophilization with different additives on the activity of protease in an organic solvent and kineteci properties was investigated.

Methods: Production conditions of protease (fermentation time, moisture level, initial pH, temperature) were optimized. After production, it was partially purified and then, lyophilized with different additives from an aqueous buffer solution containing 98% (w/w) of different additives (pumice, KCl, without additive) for 72 h after freezing in liquid nitrogen. After that, the effect of organic solvents (2.5% and 5% of DCM, ethanol, hexane, toluene) on these lyophilized protease preparations was determined and their kinetic properties were determined.

Results: Optimum protease production was obtained with 40% of moisture level, at pH 7.5, 37 °C after 24 h fermentation. It was partially purified by using ammonium sulphate precipitation (20-80%) with 5.8-fold and specific activity of 38 U/mg and then dialysed with 6.4-fold and a specific activity of 35 U/mg. Co-lyophilization of protease with pumice and KCl was increased activity of an enzyme in aqueous organic solvents when compared lyophilized protease without additive. Used solvents, except DCM, were increased activity of lyophilized protease with pumice/KCl. It was found that the lyophilization with pumice and KCl resulted in an increasing in the catalytic efficiency, while it was decreased in Km and Vmax values.

Conclusion: The obtained findings demonstrated that protease from B. subtilis can effectively be produced under SSF by using wheat bran and used in industrial applications because of showing improved activity in an organic solvent by co-lyophilization with pumice/KCl.

Published: April 2020

This study aims to reveal the development of Kajoetangan Heritage as a tourist attraction site in the city of Malang. The researchers use the Pentahelix model to look at the development. The involvement of pentahelix stakeholders (government, community, private sector, academics, and media) is intended to develop the tourism site thoroughly. So far, the main problem behind the less optimal management of Kajoetangan Heritage Tourism is the lack of development of accessibility, facilities, and infrastructure. This research uses descriptive qualitative method while the data were collected through observation, interviews, and documentation. The results show that the collaboration between the Kajoetangan community, Malang heritage community, Department of Culture and Tourism of Malang, Soak Ngalam business, City Guide FM, and Intitute of National Technology Malang had succeeded in increasing the promotion of the Kajoetangan Heritage. However, the collaboration had not been able to contribute maximally to the regional income. This happens because the problems of accessibility, facilities, and infrastructure were not resolved and there was a weak capacity of the actors involved.

Authors: Viteri Jumbo Luis , Pimentel Marco , Oliveira Eugênio E. , Toledo Pedro , D'Antonino Faroni Lêda Rita
Published: April 2020

The weevil Acanthoscelides obtectus (Say) (Coleoptera: Chrysomelidae: Bruchinae) is a cosmopolitan pest that causes high losses in stored beans in small storage units and especially on-farm storages. Here, it was tested the efficacy of the inert dust diatomaceous earth (DE) as an alternative to control A. obtectus in common beans (i.e., Phaseolus vulgaris L.) on different storage temperatures and exposure intervals. Using a Completely Randomized design four doses (0.25, 0.50, 0.75 and 1.00g kg-1) of diatomaceous earth on beans kept at different temperatures (25, 28, 30, 32 and 35°C). Insect mortality was evaluated after two or five days of exposure. The impacts of diatomaceous earth in the offspring of five days-exposed A. obtectus adults were evaluated. The offspring production (emerged adults) was evaluated 60 days after the exposure. The results revealed that A. obtectus mortality caused by diatomaceous earth was dose, temperature and exposure period dependent. For instance, at the lowest temperature (25°C), diatomaceous earth dose (0.25g kg-1 of beans) and exposure period of two days, the efficacy of diatomaceous earth was significantly reduced when compared to the other treatments. When applied at temperatures above 30°C, the diatomaceous earth treatments always resulted in A. obtectus mortality of at least 90%. Curiously, offspring production (F1) was reduced to over 95% in all diatomaceous earth, temperatures and exposure period treatments. Therefore, the results demonstrated that diatomaceous earth has the potential to be used as a tool to manage A. obtectus infestations in stored beans, considering that such control practice adequately reduced these insect infestations in several possible scenarios.

Análisis de las competencias laborales, reclutamiento y carrera funcionaria en los servicios públicos de la quinta región
Authors: Riffo Rosas Mónica Alejandra
Published: April 2020

Según Levy-Leboyer (1997; 54) las competencias son “repertorios de comportamientos que algunas personas dominan mejor que otras lo que las hace eficaces en una situación determinada”. Estos comportamientos son observables en la realidad cotidiana del trabajo e igualmente en situaciones de test. Dentro de toda organización pública, los funcionarios tienen la posibilidad de desarrollar una Carrera Funcionaria, concepto que está vinculado a una serie de etapas por las cuales un trabajador/a puede transitar. Por esto, la investigación tiene por objeto analizar las competencias laborales, reclutamiento y carrera funcionaria, que existen dentro de los servicios públicos, en la Quinta Región. Concluyendo que se debe hacer urgentemente un cambio en el Estatuto Administrativo, modificarlo de manera tal que los ascensos sean más rápidos, que las calificaciones sean especificas al trabajo realizado, que las capacitaciones sean para todos los funcionarios y también en temáticas que le sirvan para una futura postulación y, finalmente, que las Universidades estatales logren tener una mayor autonomía de la que tienen, en sus procesos administrativos y económicos.

El SARS-Cov-2 es un coronavirus productor de la enfermedad COVID-19. Esta inició en Wuhan, capital de la provincia Hubei, China. En menos de cuatro meses la enfermedad se dispersó por el mundo, lo que dio origen a miles de muertes. La Organización Mundial de la Salud (OMS) la ha declarado pandemia. La humanidad está consternada, múltiples gobiernos han obligado al aislamiento total, con éxito variable debido a la negligencia de parte de la comunidad. En muchas ciudades las instituciones y el personal sanitario no son suficientes para atender la catástrofe. El aislamiento es la única estrategia eficaz para detener el crecimiento logarítmico de COVID-19. El motivo científico del aislamiento es que más del 60 % de los contagios surgen de personas asintomáticas. La enfermedad no solo produce síntomas respiratorios. El SARS-Cov-2, además, puede producir náuseas, dolor abdominal, vómito, diarrea, anosmia y ageusia. El 50% de los infectados pueden tener síntomas digestivos, que incluso preceden a los respiratorios. La ruta fecal-oral trasmite el virus, aún sin diarrea. En las unidades de endoscopia están todas las formas de contagio: aerosoles (vómitos, arcadas, eructos, flatos), materia fecal, contacto estrecho, contaminación del ambiente. Se deben suspender todas las endoscopias programadas para diagnóstico. Solo deben realizarse las urgentes y terapéuticas.Todo el personal de endoscopia debe tener medidas de protección estrictas. El paciente debe saber que en la sala de endoscopia puede contagiarse, con constancia en el consentimiento informado. Debe contactarse al paciente posendoscopia vía telefónica a los días 7 y 14 para indagar sobre todos los síntomas mencionados.

Published: April 2020

The refined sunflower and palm oils are used in the food industry for the
production of fried potatoes. Literary data have shown that palm oil had
less tendency to degradation than sunflower oil due to its fatty acid
composition. However, palm olein is a palm oil fraction and therefore has a
different composition of fatty acids. The aim of this study was to
investigate the quality of the refined palm olein in relation to the refined
linoleic type sunflower oil during the production of fried potatoes. The oil
samples were used for multiple frying during the seven days (40 minutes per
day at a temperature of 165oC). The peroxide value and free fatty acid
content (acid value) were determined by standard analytical methods. The
results showed that the peroxide value in sunflower oil and palm olein
increased by 75.0% and 77.8%, while the acid value increased by 50.0% and
26.8%, respectively, in relation to their initial values in the fresh oil
samples. Based on these results, it can be concluded that the palm olein was
more suitable for frying. However, this finding cannot be reported with
certainty because the quality of the oil depends on many more parameters,
not only on those analysed in this paper.
Determinants of farmers’ participation in farm settlement scheme in Lagos state, Nigeria: Lessons for future rural development programmes
Authors: Obayelu Abiodun , Fabanwo James , Ayansina Simeon
Published: April 2020

In its determination to provide food and jobs for Nigerians, and appeal to
educated young men to set the pattern for farming, many state governments
have re-introduced Farm Settlement Scheme (FSS)/Graduate Employment Scheme
once abandoned. One major challenge leading to programme failure in Nigeria
is the inability to know the influence of the factors on the participation
and constraints of such programmes. This study analysed the determinants of
crop farmers? participation in FSS in Lagos State with the aim of drawing
some lessons for future rural development programmes. One hundred and thirty
(130) farmers were sampled through two-stage sampling procedures. Data were
collected with the aid of a questionnaire and were analysed using both
descriptive and inferential statistics such as the logit regression model.
Results show that about 67% of the respondents were male and 72% were
married. The major constraining factors to participation in FSS were
administrative bottlenecks, inadequate capital, and government interference.
The logit regression showed that educational level, farming experience,
extension contacts and security of land under FSS were the significant
variables (P<0.5) that directly influenced the probability of participation
of the farmers in FSS in Lagos State, Nigeria. Farming experience is very
crucial for the survival of FSS. Therefore, it is recommended that the
determinants of participation and constraints to the participation of the
farmers be assessed in any rural development programme to know the necessary
action against failure. The effort at increasing extension contacts about
FSS will further encourage farmers to participate in FSS.
Thermal management of high temperature polymer electrolyte membrane fuel cells by using flattened heat pipes
Authors: Sasiwimonrit Krerkkiat , Chang Wei-Chin
Published: April 2020

High temperature polymer electrolyte membrane fuel cell is a clean energy conversion device that generates electricity directly from the electrochemical reaction. Since the working temperature is about 160?C, the heating and cooling mechanisms are critical factors to maintain the optimal working condition and prevent the cell from degradation. Simulation models of high temperature polymer electrolyte membrane fuel cell were built for investigating the temperature distribution on the working area of fuel cells and temperature gradient across the stack. The ordinary method of heating by using heating pads and cooling by applying forced convection air was compared with the heat pipe heating and cooling technique. The results showed that heat pipe provided a more uniform temperature distribution and current density across the fuel cells stack. The temperature gradient of 0.214?C per cell during heating and 0.054?C per cell during cooling processes were observed. Meanwhile, only 0.44 mA/cm2 per cell of cur-rent density gradient was found.

In this paper, we introduced a numerical analysis for the effect of a magnetic field on the mixed convection and heat transfer inside a two-sided lid-driven cavity with convective boundary conditions on its adjacent walls under the effects of the presence of thermal dispersion and partial slip. A single-phase model in which the water is the base fluid and a copper is nanoparticles is assumed to represent the nanofluid. The bottom and top walls of the cavity move in the horizontal direction with constant speed, while the vertical walls of the cavity are stationary. The right wall is mentioned at relatively low temperature and the top wall is thermally insulated. Convective boundary conditions are imposed to the left and bottom walls of the cavity and the thermal dispersion effects are considered. The finite volume method is used to solve the governing equations and comparisons with previously published results are performed. It is observed that the increase in the Hartmann number causes that the shear friction near the moving walls is enhanced and consequently the horizontal velocity component decreases.
Computation of monthly runoff coefficients for Istanbul
Authors: Burak Selmin , Bilge Ayse , Ulker Duygu
Published: April 2020

Water demand for Istanbul is supplied both by impounded reservoirs located within its provincial boundaries and by water transfer from Western and Eastern regions in peripheral areas, located in South-West Black Sea region. The runoff coefficient defined as the ratio of the streamflow to the precipitation, plays a key role in the calculation of the surface water yield of water catchment areas. In this paper, we present the computation of monthly runoff coefficients for an accurate estimation of the yield of the catchment areas. We obtain statistical parameters for monthly temperatures and precipitation, based on 105-year data recorded at Istanbul Kandilli Observatory, modeled as Gaussian and Rayleigh distributed random variables, respectively. We run simulations to predict temperatures and precipitation over a horizon extending to 2100. We apply Turc?s formula and Thornthwaite method to obtain monthly runoff coefficients based on long-term data. The results are compared and discussed with the findings of previous researches.

Published: April 2020

This paper deals with the techno-economic analysis of gas turbine-based combined heat and power production, within a current local legislation frame for the promotion of such production of energy in the Republic of Serbia. Since the legisla?tion includes plants with electric power below 10 MW, an overview of the relevant technical characteristics for a number of appropriate gas turbines was prepared. The relevant thermodynamic parameters are calculated in order to estimate the economic feasibility of combined heat and power production using these plants. The production cost of useful heat is determined by taking into account the incomes from the sale of electricity to the electric grid under a feed-in tariff. It is compared with the production cost from an equivalent boiler for the separate production of the heat. One of the main objectives is to determine the effectiveness of the implemented legislative measures in the promotion of combined production of heat and power. Clear conclusions were drawn based on the results obtained.

Published: April 2020

Las estrategias en el proceso de enseñanza-aprendizaje-evaluación (PEAE) tienen un desempeño preponderante. El objetivo central fue analizar a tres docentes que desempeñaron rol de alumnas en el proceso de enseñanza del tema de estequiometría del nivel medio superior en el Instituto Politécnico Nacional (2016). Tradicionalmente, el PEAE se ha centrado en el cálculo y balance de sustancias químicas como estrategia de aprendizaje. Esto genera dificultades en la ejecución de operaciones aritméticas y algebraicas, las cuales son usadas como única forma de aprendizaje, lo que contribuye a los altos índices de desánimo, reprobación y deserción. En este trabajo se utilizó la plataforma Edmodo en cuatro fases: indagación documental, identificación de conocimientos previos, experiencia de una situación no rutinaria, y sentido y significado pedagógico. Los hallazgos muestran autorreflexión de las participantes en su papel como alumnas y en su quehacer docente.

The attitude of students who cannot convey what they feel without hurting the feelings of others is because the student cannot behave assertively. Assertive behavior is expressing what is felt or thought without hurting the feelings of others. This study aims to see differences in assertive behavior of students based on cultural backgrounds (Minang, Malay, Batak, Kerinci). This study uses a comparative descriptive approach carried out on BK FIP UNP students with a total sample of 248 people, using a proportional random sampling technique. The instrument of this research is a questionnaire about assertive behavior with a Likert scale model. Data were analyzed using analysis of variance (ANOVA) and data processing using SPSS version 20.00. The findings of this study indicate that there is no significant difference in assertive behavior of BK FIP UNP students when viewed from a cultural background. This means that differences in cultural background do not determine student assertive behavior. This is indicated by the calculated F value, which is equal to 0.779 while Sig. on the degree of freedom (db) 1 and aplha (?) 0.05 is 0.506, then according to hypothesis testing criteria through analysis of variance (ANOVA), if F count is greater than F table there is no significant difference.
C. S. Peirce and Josiah Royce: Understanding, self-understanding, and self-misunderstanding
Authors: Colapietro Vincent
Published: April 2020

No âmago deste artigo há uma comparação entre a investigação sobre o entendimento de Peirce o relato de interpretação de Royce. Estrutura-se por uma consideração do desentendimento de si (uma consideração desenvolvida em referência a Peirce) e, ligada a esta discussão do desentendimento de si, uma consideração sobre o próprio entendimento. Para Peirce, em razão de sua abordagem da investigação e Royce em sua meta-interpretação (i.e., sua interpretação do significado e da função da própria interpretação) alguma forma de entendimento está em jogo. Por exemplo, a tarefa do investigador científico é inacabada se ela para na descoberta de fatos nus (simplesmente que algo é verdadeiramente o caso – um corpo tal como uma pedra pequena sustentada no alto por uma pessoa cairá no solo se a pessoa soltá-la). Enquanto para ambos os pensadores, as ciências não um corpo de conhecimento seguro, mas uma forma de investigação contínua, ela visa principalmente o entendimento. Tanto Peirce quanto Royce estão animados por um compromisso com a inteligibilidade do cosmos em sua varredura plena e nos mínimos detalhes. A abordagem de Peirce sobre a investigação e a concepção de interpretação de Royce são esforços para detalhar como os atores humanos tornam cada vez mais profunda e amplamente inteligível o mundo de sua experiência. Muito pode ser aprendido comparando-os a este respeito.
