Usefulness of 5 Minutes 123I-mIBG Scan in Parkinson’s Disease and Heart Failure
Authors: Frantellizzi Viviana , Ricci Maria , Farcomeni Alessio , Pontico Mariano , Pani Arianna , Vincentis Giuseppe De
Published: January 2020

Background:

The use of 123I-mIBG has been approved for decades for Parkinson’s disease
(PD) diagnosis and as a predictor of mortality and potentially fatal events in patients with Heart Failure
(HF). The standardized technique includes an early acquisition (15 minutes from injection), and a late
acquisition (240 minutes). Early images mainly represent interstitial uptake, whereas delayed images
represent actual neuronal uptake, however, it is reasonable to affirm that different pathological situations,
such as PD and HF, imply a different meaning for early and late imaging.

Objective:

This prospective study aims to investigate the clinical usefulness of an immediate planar
123I-mIBG image acquisition (5 minutes) both in patients with PD and in patients with HF.

Methods:

115 patients referred to 123I-mIBG cardiac imaging in Nuclear Medicine Center have been
enrolled (60 patients with PD, absence of diabetes and/or cardiologic pathology, Hoehn e Yahr classification
≤ 1.5; 55 patients with cardiomyopathy, diagnosis of HF, NYHA class I–III). 123I-mIBG planar
anterior thoracic acquisitions were performed after 5 (immediate), 15 (early) and 240 (late) minutes
from injection and H/M ratios were calculated.

Results:

In PD group H/M mean values resulted in 1.58±0.22 for immediate (5 min), 1.61±0.26 for
early (15 min) and 1.59±0.37 for late (240 min) acquisitions. In the HF group, H/M mean values resulted
in 1.63±0.24 for immediate (5 min), 1.65±0.22 for early (15 min) and 1.57±0.17 for late (240
min) acquisitions, respectively. H/M values obtained at 5 min and 15 min are provided similar results,
with no statistical difference (p = ns) regardless of the pathology examined (PD or HF groups). The
statistical analyses validated the diagnostic role of immediate acquisition (5 min) and early acquisition
(15 min) in PD group as compared to the standardized late acquisition (240 min). On the contrary, in
HF group, immediate and early acquisition, as compared to late acquisition (240 min), is not validated
as a major cardiac events predictor.

Conclusion:

Our results indicate the potential role of immediate (5 min) or early (15 min) acquisition
in replacement of standardized 240 minutes acquisition in PD patients, but this result is not confirmed
in HF patients, in which the acquisition at 240 min is confirmed as the most affordable timing for image
interpretation, emphasizing the different pathophysiology that underlies these two pathologies.
Expression of Salivary miRNA 21 in Oral Submucous Fibrosis (OSMF): An Observational Study
Authors: Prasad Shesha R. , Pai Anuradha , Shyamala K. , Yaji Anisha
Published: January 2020

Objective:

To observe the expression patterns of salivary mRNA 21 in different stages and
grades of OSMF and also in habitual areca nut chewers without OSMF.

Subjects and Methods:

The study consisted of a total of 185 samples, where 61 patients had chewing
habits (chewing gutkha and other forms of areca nut) and had OSMF (Group 1). 61 patients had
chewing habits but did not have OSMF (Group 2), and 63 were normal healthy patients (control
group) without any chewing habits (Group 3). Unstimulated saliva samples were collected from patients
following the standard operating procedures. miRNA 21 was isolated and purified from saliva
samples using the miRNeasy Mini Kit, Qiagen. The primers for miRNA relative quantification analysis
were designed using the Primer Express software of Applied Biosystems. Quantification of all
the samples was carried out using SYBR chemistry in an Applied Biosystems Real-Time PCR.

Results:

There was no statistically significant difference between the demographic characteristics of
patients. There was a statistically significant difference between the expressions of miRNA 21
amongst the three groups noted in Kruskal Wallis test. (<0.001*) A post hoc test was perfomed to
confirm the statistical difference between patients within all three groups. There was no statistically
significant difference noted between the OSMF group and patients with chewing habits group (G1
vs. G2 p: 0.10), but there was a significant difference when compared with normal patients. (G1 vs.
G3 p: <0.001*) and (G2 vs. G3 <0.001*).

Conclusion:

This study concludes that miRNA 21 is overexpressed in OSMF and chewing habit patients.
But the expression levels were not significantly associated with the severity of the disease process.
A long term and large scale studies are required to assess its application as a diagnostic profibrotic
marker in OSMF.
Proposal for the User-Centered Design Approach for Health Apps Based on Successful Experiences: Integrative Review
Authors: Molina-Recio Guillermo , Molina-Luque Rafael , Jiménez-García Ana M. , Ventura-Puertos Pedro E , Hernández-Reyes Alberto , Romero-Saldaña Manuel
Published: January 2020

Background

Different strategies encompassed within mHealth have shown themselves to be effective for maintaining good health or controlling certain diseases. However, there is usually a very high rate of abandonment of health apps. Therefore, it would seem obvious that there is a need for involving the end users (whether they are health professionals, patients, or both) in the design process from the early stages in order to enable their needs and characteristics to be identified. In this sense, it is common knowledge that focusing on the user permits the consideration of valuable details aimed at making the correct adjustment between the patient, the technology, and the organization of attention.

Objective

The goal of the research was to propose a methodology based on the review of previous successful user experiences in setting up health apps by using qualitative techniques (focus groups and discussion groups) that includes the participation of information technology and health professionals and the patients themselves.

Methods

An integrative review was made of studies in which a qualitative methodology was employed mainly through focus and/or discussion groups for the design and development of health apps, consulting diverse databases (PubMed, Scopus, and Proquest) with the following search strategy: “mHealth AND apps AND focus group OR discussion group.” A total of 69 papers were included in the review.

Results

A proposal structured in 4 sessions of variable duration was made in which information technology and health professionals and patients take part: composing, preparing, and organizing contents (session 1); testing structure and usability (session 2); does the app fit the needs of end users? (session 3); and last testing—keep on improving (session 4). Throughout the sessions, we propose studying aspects like previous user experiences in mHealth, barriers to the adoption of mHealth, interface contents, management and browsability, usability, perceived quality, security and privacy, capacity to self-manage disease with the app, ergonomics, and glanceability, etc. Specific tools that have proved useful in previous research for measuring these aspects are presented.

Conclusions

These work sessions would be based on predominantly qualitative methodologies although, as they evolve, validated questionnaires permitting the assessment of the objectivity of certain technical aspects could be incorporated. With this proposal, a project centered on end users could be effected, responding to their needs. However, this requires validation that will be made via implementation in the development of health apps, with the subsequent measurement of results in terms of adherence and improvement in the clinical variables of the end users.
Effectiveness of Mobile Health Interventions on Diabetes and Obesity Treatment and Management: Systematic Review of Systematic Reviews
Authors: Wang Youfa , Min Jungwon , Khuri Jacob , Xue Hong , Xie Bo , A Kaminsky Leonard , J Cheskin Lawrence
Published: January 2020

Background

Diabetes and obesity have become epidemics and costly chronic diseases. The impact of mobile health (mHealth) interventions on diabetes and obesity management is promising; however, studies showed varied results in the efficacy of mHealth interventions.

Objective

This review aimed to evaluate the effectiveness of mHealth interventions for diabetes and obesity treatment and management on the basis of evidence reported in reviews and meta-analyses and to provide recommendations for future interventions and research.

Methods

We systematically searched the PubMed, IEEE Xplore Digital Library, and Cochrane databases for systematic reviews published between January 1, 2005, and October 1, 2019. We analyzed 17 reviews, which assessed 55,604 original intervention studies, that met the inclusion criteria. Of those, 6 reviews were included in our meta-analysis.

Results

The reviews primarily focused on the use of mobile apps and text messaging and the self-monitoring and management function of mHealth programs in patients with diabetes and obesity. All reviews examined changes in biomarkers, and some reviews assessed treatment adherence (n=7) and health behaviors (n=9). Although the effectiveness of mHealth interventions varied widely by study, all reviews concluded that mHealth was a feasible option and had the potential for improving patient health when compared with standard care, especially for glycemic control (−0.3% to −0.5% greater reduction in hemoglobin A1c) and weight reduction (−1.0 kg to −2.4 kg body weight). Overall, the existing 6 meta-analysis studies showed pooled favorable effects of these mHealth interventions (−0.79, 95% CI −1.17 to −0.42; I2=90.5).

Conclusions

mHealth interventions are promising, but there is limited evidence about their effectiveness in glycemic control and weight reduction. Future research to develop evidence-based mHealth strategies should use valid measures and rigorous study designs. To enhance the effectiveness of mHealth interventions, future studies are warranted for the optimal formats and the frequency of contacting patients, better tailoring of messages, and enhancing usability, which places a greater emphasis on maintaining effectiveness over time.
Experiences of Internet-Based Stepped Care in Individuals With Cancer and Concurrent Symptoms of Anxiety and Depression: Qualitative Exploration Conducted Alongside the U-CARE AdultCan Randomized Controlled Trial
Authors: Hauffman Anna , Alfonsson Sven , Igelström Helena , Johansson Birgitta
Published: January 2020

Background

Individuals with newly diagnosed cancer may experience impaired health in several aspects and often have a large need for information and support. About 30% will experience symptoms of anxiety and depression, with varying needs of knowledge and support. Despite this, many of these patients lack appropriate support. Internet-based support programs may offer a supplement to standard care services, but must be carefully explored from a user perspective.

Objective

The purpose of this study was to explore the participants’ perceptions of the relevance and benefits of an internet-based stepped care program (iCAN-DO) targeting individuals with cancer and concurrent symptoms of anxiety and depression.

Methods

We performed a qualitative study with an inductive approach, in which we used semistructured questions to interview 15 individuals using iCAN-DO. We analyzed the interviews using content analysis.

Results

The analysis found 17 subcategories regarding the stepped care intervention, resulting in 4 categories. Participants described the need for information as large and looked upon finding information almost as a survival strategy when receiving the cancer diagnosis. iCAN-DO was seen as a useful, reliable source of information and support. It was used as a complement to standard care and as a means to inform next of kin. Increased knowledge was a foundation for continued processing of participants’ own feelings. The optimal time to gain access to iCAN-DO would have been when being informed of the diagnosis. The most common denominator was feeling acknowledged and supported, but with a desire for further adaptation of the system to each individual’s own situation and needs.

Conclusions

Users saw the internet-based stepped care program as safe and reliable and used it as a complement to standard care. Similar interventions may gain from more personalized contents, being integrated into standard care, or using symptom tracking to adjust the contents. Offering this type of program close to diagnosis may provide benefits to users.

Influencing Pain Inferences Using Random Numerical Anchoring: Randomized Controlled Trial
Authors: Lewinson Rebecca Elizabeth , Katz Joel D
Published: January 2020

Background

Numerical anchoring occurs when exposure to a numeric quantity influences a person’s subsequent judgment involving other quantities. This could be applicable to the evaluation of pain, where exposure to an unrelated number before the evaluation of pain could influence pain ratings.

Objective

This study aimed to determine whether exposure to a random numeric anchor influences subsequent pain intensity ratings of a hypothetical patient.

Methods

In this study, 385 participants read a vignette describing a patient with chronic pain before being randomly assigned to one of four groups. Groups 1 and 2 spun an 11-wedge number wheel (0-10), which was, unbeknown to the participants, programmed to stop on a high number (8) or a low number (2), respectively. Group 3 spun a similar letter wheel (A-K), which was programmed to stop on either the letter C or I (control 1). Group 4 did not spin a wheel (control 2). Participants were then asked to rate the patient’s pain intensity using a 0 to 10 numeric rating scale.

Results

The high-number group rated the patient’s pain (median 8, IQR 2) significantly higher than the letter wheel control (median 7, IQR 2; P=.02) and the low-number group (median 6, IQR 2; P<.001). The low-number group rated the pain significantly lower than controls 1 and 2 (median 7, IQR 2; both P=.045).

Conclusions

Pain ratings were influenced by prior exposure to a random number with no relevant information about the patient’s pain, indicating anchoring had occurred. However, contrary to the traditional definition of anchoring where anchoring occurs even when participants are unaware of the anchor’s influence, in this study, the anchoring effect was seen only in participants who believed that the anchor had influenced them. This suggests that anchoring effects could potentially occur among health care providers tasked with evaluating a patient’s pain and should be evaluated further.

Authors: Anthony Chris A , Rojas Edward Octavio , Keffala Valerie , Glass Natalie Ann , Shah Apurva S , Miller Benjamin J , Hogue Matthew , Willey Michael C , Karam Matthew , Marsh John Lawrence
Published: January 2020

BACKGROUND

Acceptance and commitment therapy (ACT) is a pragmatic approach to help individuals decrease avoidable pain.

OBJECTIVE

This study aims to evaluate the effects of ACT delivered via an automated mobile messaging robot on postoperative opioid use and patient-reported outcomes (PROs) in patients with orthopedic trauma who underwent operative intervention for their injuries.

METHODS

Adult patients presenting to a level 1 trauma center who underwent operative fixation of a traumatic upper or lower extremity fracture and who used mobile phone text messaging were eligible for the study. Patients were randomized in a 1:1 ratio to either the intervention group, who received twice-daily mobile phone messages communicating an ACT-based intervention for the first 2 weeks after surgery, or the control group, who received no messages. Baseline PROs were completed. Two weeks after the operative intervention, follow-up was performed in the form of an opioid medication pill count and postoperative administration of PROs. The mean number of opioid tablets used by patients was calculated and compared between groups. The mean PRO scores were also compared between the groups.

RESULTS

A total of 82 subjects were enrolled in the study. Of the 82 participants, 76 (38 ACT and 38 controls) completed the study. No differences between groups in demographic factors were identified. The intervention group used an average of 26.1 (SD 21.4) opioid tablets, whereas the control group used 41.1 (SD 22.0) tablets, resulting in 36.5% ([41.1-26.1]/41.1) less tablets used by subjects receiving the mobile phone–based ACT intervention (P=.004). The intervention group subjects reported a lower postoperative Patient-Reported Outcome Measure Information System Pain Intensity score (mean 45.9, SD 7.2) than control group subjects (mean 49.7, SD 8.8; P=.04).

CONCLUSIONS

In this study, the delivery of an ACT-based intervention via an automated mobile messaging robot in the acute postoperative period decreased opioid use in selected patients with orthopedic trauma. Participants receiving the ACT-based intervention also reported lower pain intensity after 2 weeks, although this may not represent a clinically important difference.

Published: January 2020

One of important tasks in a development of gas-condensate fields is to minimize hydrocarbons loss arising from the gas condensation in pores of the gas-bearing layer. The search for the optimal gas production regime is carried out both on the basis of laboratory experiments and on the base of computer simulation. In this regard, the relevant is the verification of the constructed mathematical models by means of comparison of numerical results with experimental data obtained on the laboratory models of a hydrocarbon reservoirs. Within the classical approach on the basis of the Darcy law and the law continuity for flows, the model is formulated that describes the passing a multicomponent gas-condensate mixture through a porous medium in the depletion mode. The numerical solution of the corresponding system of nonlinear partial differential equations is implemented on the basis of the combined use of the C++ programming language and the Maple software. Shown that the approach used provides an agreement of results of numerical simulations with experimental data on the dynamics of hydrocarbon recoverability depending on the pressure obtained at VNIIGAZ, Ukhta.
On the properties of numerical solutions of dynamical systems obtained using the midpoint method
Authors: Gerdt Vladimir P. , Malykh Mikhail D. , Sevastianov Leonid A. , Ying Yu
Published: January 2020

The article considers the midpoint scheme as a finite-difference scheme for a dynamical system of the form ̇ = (). This scheme is remarkable because according to Cooper’s theorem, it preserves all quadratic integrals of motion, moreover, it is the simplest scheme among symplectic Runge-Kutta schemes possessing this property. The properties of approximate solutions were studied in the framework of numerical experiments with linear and nonlinear oscillators, as well as with a system of several coupled oscillators. It is shown that in addition to the conservation of all integrals of motion, approximate solutions inherit the periodicity of motion. At the same time, attention is paid to the discussion of introducing the concept of periodicity of an approximate solution found by the difference scheme. In the case of a nonlinear oscillator, each step requires solving a system of nonlinear algebraic equations. The issues of organizing computations using such schemes are discussed. Comparison with other schemes, including those symmetric with respect to permutation of and .̂

O ato de linguagem segundo a Semiolinguística: implicações, explicações e aplicações práticas
Authors: Machado Ida Lucia
Published: January 2020

Neste artigo, gostaríamos de tecer algumas considerações sobre um dos conceitos importantes da Semiolinguística de P. Charaudeau, teoria que utilizamos em corpora diversos há mais de 20 anos. Iremos discorrer sobre o que o teórico nomeia ato de linguagem, suas implicações e aplicações práticas. Para tanto, ilustraremos nossos ditos com enunciados extraídos do livro Esquisse pour une auto-analyse (2004), do sociólogo Pierre Bourdieu. Escolhemos escritos desse autor, justamente nesse livro, pois eles se integram, de certa maneira, às nossas pesquisas atuais sobre análise do discurso e narrativas de vida. A análise do discurso proposta por Charaudeau, além disso, carrega em si uma interface com a sociologia. Nosso objetivo é mostrar como conceitos vindos da Semiolinguística são importantes e práticos, ao permitir a realização de possíveis interpretativos de diferentes escritos.
As relações retóricas de hiperligações de notícias de divulgação científica digitais e a encenação midiática
Authors: Giering Maria Eduarda
Published: January 2020

Este artigo apresenta resultados de uma pesquisa quantitativa que examinou notícias de divulgação científica hipertextuais publicadas na imprensa brasileira. Partimos do link (ou da hiperligação) e investigamos a relação retórica que se estabelece entre o texto de origem e o texto de destino (verbal ou não verbal) a que o produtor remete o leitor, direcionando-o para um possível percurso de leitura. Assumimos a hipótese de que o gênero discursivo exerce papel regulador das relações retóricas que emergem de hiperligações assim como a encenação midiática da divulgação da ciência protagonizada pelas revistas. O corpus de estudo foram 150 notícias de divulgação da ciência, 50 exemplares de cada uma das revistas: Superinteressante, Galileu e Ciência Hoje. Para a investigação, convocaram-se a Teoria Semiolinguística do Discurso e a Rhetorical Structure Theory (RST). A primeira forneceu-nos as bases para pensarmos as restrições discursivas da midiatização da ciência; a segunda, os fundamentos para identificarmos a relação retórica que emerge da estrutura da hiperligação. Os resultados mostram recorrência de um número limitado de relações retóricas e, entre as revistas, variações percentuais de ocorrência de relações, apontando para a influência do gênero discursivo e da encenação midiática que cada publicação propõe.
Polissemia e interdiscursividade nos cartuns de Bruno Drummond: uma abordagem linguístico-discursiva
Authors: Valente André Crim
Published: January 2020

O estudo aqui apresentado utiliza uma abordagem linguístico-discursiva dos cartuns de Bruno Drummond. Estabelece, inicialmente, uma distinção, no campo do humor gráfico, entre charge, cartum e caricatura. A seguir, destaca as características do cartum. Para a análise do corpus, recorre-se aos conceitos de polissemia e interdiscursividade estabelecendo a diferença entre esta e a intertextualidade. Na fundamentação teórica do humor gráfico, priorizam-se as considerações de Teixeira (2001 e 2005) e do autor (2007) em análise. No que respeita ao binômio interdiscursividade/intertextualidade, dá-se destaque aos estudos de Jenny (1979), Orlandi (2001) e Fiorin (2003). Na abordagem da polissemia, na comparação com a homonímia e a sinonímia, valorizam-se as obras de Borba (1970), Gonzáles et al. (1989). Por fim, também deram suporte à análise do corpus as considerações de Charaudeau (no prelo) sobre inferências discursivas.
Diseño del encofrado para muros usando encofrados modulares
Authors: Martínez Carlos A. , Díaz Juan F. , Duque Robinson
Published: January 2020

El concreto u hormigón es uno de los materiales más versátiles usados en la construcción.  En la actualidad, se usa extensivamente en la industria, ya que puede ser moldeado de formas casi arbitrarias a través de moldes rígidos denominados encofrados. La manera en que se disponen los distintos elementos para formar el encofrado y las restricciones asociadas, genera retos computacionales interesantes que impactan directamente la industria de la construcción. En este artículo se propone la implementación de un modelo de restricciones que genera encofrados para muros rectilíneos usando formaletas modulares. Este enfoque se basa en la descomposición de muros y su representación en instancias del problema de cambio de monedas. Para este propósito, se utiliza el concepto de descomposición rectangular orientada para simplificar la entrada del problema y abordar la solución como un problema de optimización por restricciones (COP). Los experimentos con entradas de prueba ofrecen soluciones en tiempos inferiores a 200 segundos, cuyo resultado es un enfoque práctico y eficiente para la compleja tarea del diseño de encofrados.

Moslem womenâ€™s participation in sustainable household clean water management: The case of Sekaran District
Authors: Ulya Annida Unnatiq
Published: January 2020

Environment is easily changing through urban development and people's growth. In this situation, the availability of clean water would be threatened unless it has a good water management. The purpose of this research is to examine Moslem womenâ€™s participation in the sustainable household clean water management. This descriptive research analyses quantitative and qualitative data collected using questionnaire and interview towards 50 household women. The sampling methods employ accidental sampling in the Moslem community. This research has found that household clean water management has not been optimally done yet, so it could not perform the water use efficiency for environment and water sustainability although the womenâ€™s participation rate is high (75,40). In addition, the teaching of Islam has not emerged as the basic principle for water management by Moslem women in their household shown by the lack of sustainable water management practices.

Plastic waste becomes a global environmental problem that is still difficult to overcome by countries over the world, including Indonesia. In fact, Indonesia is the second largest contributor of plastic waste in the world. This problem is even not only encountered by the countries, but also faced by a small town such as Salatiga, Central Java. To overcome the problem, the society should actively be the pioneer since they are the main producer of plastic waste. However, our previous research showed that the households performed limited efforts to manage the waste, and unexpectedly, any activity of waste collection was preferably motivated by financial reasons. Therefore, this study sheds light on the housewivesâ€™ perception on plastic and their awareness in managing waste, especially plastic waste. The data of this quantitative study were gathered by means of interview, survey, observation, and documentation from 96 housewives in 6 RW in Kecandran, Sidomukti Sub-District, Salatiga as the participants. The results showed that approximately 60% of the housewives in Kecandran village, Sidomukti sub-district were able to differentiate which waste belonged to non-biodegradable and biodegradable as well as to understand the negative impact of plastic waste toward the environment. They also participated in managing the plastic waste by sorting them (64.58%), participating in waste banks or Bank Sampah (53.13%), and reducing the plastic waste (64.58%). In addition, 85.42% of them were willing to support the government policy in reducing the use of plastic, and 40% of them participated in the payable plastic policy. The role of Bank Sampah is really important to equip the housewives with environmental knowledge. In terms of the payable plastic policy, however, their understanding is not necessarily followed by the willingness to act, which might be related to different orientations and motives.

Published: January 2020

Inherently UWB (Ultra Wideband) communication systems comes with interference problem with some if the existing narrowband communication systems. These bands are stopped with the help of band-stop filter in order to reduce electromagnetic interference However, the complexity and limitations are increased due to these filters, hence this solution is turned down in those applications where design complications and complexity is of concern. Introducing various slots of specific shapes and exact dimensions however, have solved this issue for the researchers around the world. This paper presents a hexagonal PMA (Printed Monopole Antenna) with triple stop bands. The antenna is used for UWB application. The antenna is stopped the WiMAX (Worldwide Interoperability for Microwave Access), WLAN (Wireless Local Area Network) and ITU (International Telecommunication Union) bands. The antenna dimensions are 30x28x16 mm3. FR4 is used between ground and radiating patch with relative permittivity of 4.4. The VSWR (Voltage Standing Wave Ratio) is less than 2 between 3-11 GHz except WiMAX (3.1-3.7 GHz), WLAN (5.1-5.8 GHz) and the ITU frequency band (7.95-8.4 GHz). The antenna is design in CST software.
Blagojevićev Pjesnik-putnik (1771) u kontekstu „katoličkoga prosvjetiteljstva“
Authors: Šutalo Goranka
Published: January 2020

Adam Tadija Blagojević (1745. ili 1746. – nakon 1797.) u hrvatskoj je književnoj historiografiji atribuiran kao najizrazitiji predstavnik jozefinizma u slavonskoj književnosti, što svakako potvrđuje i njegov nevelik književni opus, a ponajprije jedino izvorno autorovo djelo – spjev Pjesnik-putnik, nikoji događaji prvo i posli puta Josipa II. cesara rimsko-nimačkoga u Slavoniju (1771). Unatoč tome što je hrvatska književna historiografija prilično dobro opisala Blagojevićeva djela, čini se da je njihov prosvjetiteljski predznak još uvijek nedovoljno precizno pojašnjen. U radu se stoga Blagojevićev Pjesnik-putnik nastoji promotriti s aspekta katoličkog prosvjetiteljstva, čije se naznake u spjevu mogu primijetiti.
Osječko građanstvo u Upisniku građana od stjecanja slobodnog i kraljevskog statusa do prvog popisa neplemenitog stanovništva (1809.-1814.)
Authors: Lovaš Eldina
Published: January 2020

U radu se na temelju podataka evidentiranih u osječkom Upisniku građana analizira osječko građanstvo između 1809. i 1814. godine. U radu se daje kratak opis izvora koji omogućavaju istraživanje osječkih građana, navode se građanska prava koja su zajamčena Poveljom slobodnog i kraljevskog grada Osijeka iz 1809. godine te uvjeti primanja u građanstvo. Analiza podataka temelji se na Upisniku jer taj izvor donosi najviše pojedinačnih podataka o svakom građaninu. Primjenom statističke, komparativne i deskriptivne metode nastoji se prikazati broj, vjerska i „nacionalna“ struktura, bračni status i vrste djelatnosti osječkih građana. Rad obuhvaća razdoblje od 1809., kada je Osijek stekao slobodni i kraljevski status, do 1814. godine, kada je osječko neplemenito stanovništvo prvi put popisano. To je, dakle, prvi popis neplemenitih građana nakon što je Osijek proglašen slobodnim i kraljevskim gradom.
Farm Householdsâ€™ Livelihood Diversification into Agro-processing and Non-agro-processing Activities: Empirical Evidence from Ghana
Authors: Kuwornu John K.M. , . Moses Dumayiri
Published: January 2020

This study seeks to identify the types of agro-processing and non-agro-processing activities in the Upper West Region of Ghana and the factors influencing householdsâ€™ choice of diversification into each of these groups of activities as livelihood strategies. The study employs the multinomial logit model to identify the determinants of diversification. Data were obtained from a survey conducted by the International Food Policy Research Institute (IFPRI) in December, 2012 covering production activities for the 2011 agricultural year. The Primary data were collected from two hundred and fifty (250) food crop farmers selected using a multistage sampling procedure. The empirical results indicate that households in the Upper West Region diversify their livelihoods activities to agro-processing and activities not related to agro-processing. Households who are likely to diversify are females who are high income earners with small farm sizes. Further, educated and asset-rich farmers who produce for subsistence only are more likely to diversify to agro-processing while access to credit will influence diversification but not necessarily into agro-processing. These results have implications for the development of agro-processing ventures in developing countries.
Rereading Jean Lave 30 years on: Analogy and transfer-in-pieces
Authors: Hansen Stig Børsen
Published: January 2020

This paper explores and evaluates some of the criticisms of a cognitive approach to learning leveled by Lave in Cognition in Practice (1988). The paper progresses by initially identifying learning transfer as the focal topic of Lave’s work. Two lines of criticism are identified, one called practice-based and one called concept-based. Through a renewed analysis of one of the empirical cases reported by Lave, I set out to show how this empirical material did not lend itself to Lave’s conclusions, in so far as these conclusions rejected central tenets of cognitive theories of learning. Concerning the concept-based line of criticism, I show how the phenomenon of analogically related uses of words plays a role in defusing one version of the concept-based line of criticism. Concerning the practicebased criticism, I show how an oft-overlooked form of analogical inference, coupled with elements of a cognitive, transfer-in-pieces approach, offers a better account of Lave’s case than the one she offered. The paper concludes with reflections on the lasting significance of Lave’s work.

Authors: Cristina de Sousa Amanda , Carlos de Proença Marcelo
Published: January 2020

O objetivo do artigo foi analisar a contribuição da implementação de uma proposta de ensino via resolução de problemas para favorecer a compreensão de equação do primeiro grau com uma incógnita. Realizamos uma pesquisa participante, envolvendo 34 alunos do sétimo ano do ensino fundamental de escola pública. Registramos suas estratégias de resolução, bem como a participação e motivação ao longo das aulas. Os resultados mostraram que a estratégia tentativa e erro foi a mais utilizada pelos grupos, os quais conseguiram resolver os dois problemas propostos, exceto um grupo que teve dificuldades na etapa de representação ao buscar resolver o problema 2. Os resultados também mostraram que a turma é pouco participativa e houve o desinteresse de alguns alunos. Concluímos que o auxílio da professora-pesquisadora foi fundamental para que os alunos conseguissem resolver os problemas e, assim, compreender a equação de 1.º grau com uma incógnita.
