Mediale Optimierung der Kindheit?
Authors: Sauerbrey Ulf , Schick Claudia
Published: May 2021

Neben Ratgebern für Eltern und Lehrpersonen existieren ebenso Ratgebermedien, die sich an Kinder richten und die diesen zu verschiedenen Themen Ratschläge bezüglich einer Verhaltungsoptimierung darbieten. Da hierzu bislang kaum Forschungsliteratur existiert, stellt der Beitrag eine Untersuchung vor, in der an Kinder in der mittleren Kindheit adressierte mediale Ratgeberangebote auf dem Buchmarkt und im Internet erhoben und mit Blick auf die angebotenen Themen inhaltsanalytisch ausgewertet wurden. Diese zeigen sich heterogen: Auf dem Buchmarkt wird vor allem Rat zu den Themen Aufklärung/Sexualität, Selbstbewusstsein/Selbstbestimmung, Soziales Verhalten/Streit/Konfliktlösung sowie Umwelt/Nachhaltigkeit gegeben. Im Internet hingegen finden sich zum Teil Themen, die auf dem Buchmarkt nicht vorkommen. Von den entsprechenden Themenüberblicken ausgehend wird anhand eines dokumentenanalytisch ausgewerteten Samples zudem eine erste Charakteristik der kommunikativen Elemente medialer Kinderratgeber herausgearbeitet. Hierbei zeigen sich Blogs im Vergleich zu Büchern überraschenderweise weniger vielfältig. Allerdings ist zu vermuten, dass sich digitale Ratgeberangebote in Bezug auf die gewählten Themen näher an der medialen Lebensrealität von Kindern in Deutschland bewegen. Basierend auf diesen ersten Ergebnissen werden Strategien für die künftige Erforschung von Ratgebermedien für Kinder auf der Angebotsseite vorgeschlagen.

In today’s era, as we all know how the year 2020 has brought an alarming pandemic with it and day by day, we are reaching a new peak of COVID cases. And due to which a main contribution asked from all the citizens is to follow all the safety norms to soothe the condition. One of the norms states to wear facemask all the time immediately after stepping out of their home. This paper proposes one of the methods to ensure that at least all people coming under any Closed-Circuit Television (CCTV) surveillance wears masks and that too properly. In this system we are using locally linear embedding (LLE) algorithm for face detection and convolutional neural network (CNNs) to reconfigure the image to fit into the network. And the neural network is trained with the help of image dataset. The method attains training accuracy and validation accuracy up to 99.87% and 93.41% respectively on two different datasets. If the system found out a person with no mask or not wearing it properly an alarm buzz outs to alter.

Authors: Casarin Fabiana , Dourado Camila , Sousa Luana , Grassi Marco , Dias Ana
Published: May 2021

A hybrid imprinted polymer (HMIP) was synthetized via sol-gel technique in aqueous solution for caffeine separation from environmental waters samples. The optimal conditions of synthesis were stablished by application of a 23 full factorial experimental design with three factors: ratio of functional monomer and cross-linker reagent, and acid or basic catalyst (HCl or NH4OH). The HMIP obtained with the factorial designs was 22.5 times more selective for caffeine than control polymer, with an adsorption mechanism of pseudo-second order with two sorption sites. The maximum equilibrium adsorption capacity was 1.91 mg g-1 that was maintained until ten cycles of reuse, indicating their excellent stability. The material was 21 times more selective for caffeine than for its analogous molecules (theophylline and theobromine). HMIP was applied in solid phase extraction (SPE) procedure and caffeine extraction of surface water had good recoveries (93.0%).These results demonstrated that the factorial experimental design resulted in an efficient and selective sorbent for caffeine with a reduction of number of synthesis and problems of trial‑and‑error protocol as well as reagents consumption decrease.

Effect of local calibration on the performance of the Hargreaves reference crop evapotranspiration equation
Authors: Niranjan S. , Nandagiri Lakshman
Published: May 2021

Obtaining accurate estimates of reference crop evapotranspiration (ET0) using limited climatic inputs is essential in data-short situations where the preferred FAO-56 Penman–Monteith (PM) equation cannot be implemented. Among several available for ET0 estimation, the empirical temperature-based Hargreaves–Samani (HG) equation remains a popular alternative. However, accurate HG estimates can be obtained by local calibration and replacing the mean daily temperature with the effective daily temperature. Therefore, the present study was taken up to evaluate the effects of site-specific calibration of model parameters and the use of effective air temperature on the accuracy of ET0 estimates by the HG model. For this purpose, climate records for the historical period 2006–2016 of 67 stations located across 10 agro-climatic zones of Karnataka State, India, were used and the analysis was carried out using a monthly time step. Calibration and statistical performance evaluation was performed using FAO-56 PM ET0 estimates as a reference. Overall results showed significant improvement in HG estimates across all zones with the use of locally calibrated parameters, whereas the use of effective air temperature did not lead to any significant gain in prediction accuracies. The derived information on the spatial distribution of calibrated parameters will help obtain accurate ET0 estimates with only air temperature inputs.

Published: May 2021

Hg(II) ions in wastewater are highly toxic to the environment and human health, yet many materials to remove the ions exhibit lower adsorption efficiency, and few studies report the reuse of Hg(II)-loaded waste materials. Here, a cheap and efficient adsorbent was prepared for the removal of Hg(II) based on corn bracts (CB) loading copper sulfide (CuS), and the Hg(II)-adsorbed material was reused as a photocatalyst. By changing the adsorption variables such as pH, adsorbent dosage, Hg(II) concentration, contact time and coexisting ions, the optimum adsorption conditions were obtained. The study indicated the adsorption capacity and removal rate of CB/CuS reached 249.58 mg/g and 99.83% at pH 6 with 20 mg CB/CuS, 50 mL Hg(II) concentration (100 mg/L) and 60 min, and coexisting ions did not affect the uptake of Hg(II). The adsorption behavior of CB/CuS toward Hg(II) followed pseudo-second-order and Langmuir models, with the theoretical maximum adsorption capacity of 316.46 mg/g. Finally, we explored an alternative strategy to dispose of spent adsorbents by converting the CB/CuS/HgS into a photocatalyst for the degradation of rhodamine B, with a removal rate of 98%. Overall, this work not only develops a promising material for the treatment of Hg(II)-containing wastewater, but opens up a new approach for the use of the waste adsorbent.
Effect of Modifications in Poly (Lactide-co-Glycolide) (PLGA) on Drug Release and Degradation Characteristics: A Mini Review
Authors: Singh  , Singha Prabha
Published: May 2021

:

The use of PLGA in the pharmaceutical industry has only increased as we move towards
more and more advanced delivery carrier systems. The qualities of PLGA like biocompatibility,
biodegradability and a tunable degradation and drug release has only helped in keeping up the release
requirements desired for various delivery platforms. Fine-tuning the release and degradation
rate is gaining more and more attention as researchers keep pushing the boundaries of novel delivery
carriers. Various experiments are being performed to understand the degradation behavior of
PLGA under various physiological and process-related conditions. The understanding of these parameters
has helped formulate various ways in which one can fine-tune the properties that can lead
to the release of active ingredients encapsulated within. Various techniques have been tried and tested
including changes like chemical modification, physical blending and surface modifications and
have found to be effective means of release modulation in delivery systems like parenteral, orals,
topicals and tissue engineering scaffolds. In this review, all these experiments and implications
thereon have been discussed in detail.

Published: May 2021

:

Despite the marked improvement in overall survival rates of paediatric patients with haematological
malignancies that has been achieved during the last decades, there is still a pressing
need for novel therapeutic approaches for the subset of patients with relapsed or refractory disease.
Immune checkpoint inhibitors aim to induce potent anti-tumour immune responses by targeted
blocking of inhibitory receptors and have shown promising results in preclinical models and
studies on the adult population. However, paediatric malignancies present unique features, and so
far, experience with these agents is limited. In the current review, we present an overview of efficacy
and safety data from case reports, case series, and clinical trials employing the use of immune
checkpoint inhibitors in children, adolescents, and young adults with haematological malignancies.
We also discuss new possibilities involving novel targets and combination treatments and provide
a summary of the currently registered clinical trials.

Authors: Bekere Yadeta Bekele , Megersa Guta Regasa
Published: May 2021

Certification is an instrument to add value to a product, and it addresses a growing worldwide demand for healthier and more socially and environmentally friendly products. Globally, coffee certification has received strong recognition as it is proved to increase smallholder farmers’ access to input and output markets, production, productivity and income. This study investigates the major determinants of coffee certification participation. It also analyzes the welfare gains of participation in the certification schemes by smallholder coffee growers. Both primary and secondary data were used. Primary data were collected from randomly selected 247 coffee producers. Structured questionnaires, focus group discussions and key informant interviews were employed to collect the primary data. Descriptive statistics and econometric models were used for data analysis. Probit model was used to identify factors affecting participation in coffee certification schemes. Propensity score matching technique was used to estimate the impact of coffee certification participation on smallholders’ annual revenue from coffee production. The probit model result revealed that access to training, family size, land size owned, experience in coffee production, education status were significantly determined the smallholders farmers’ participation decision in coffee certification. The propensity score matching model result also shows that participation in coffee certification significantly (p=0.001) improved farmers’ annual revenue by 2,902 Ethiopian birr compared to selling coffee without the certification schemes. This income impact is mainly attributed to the premium price the certification offer to farmers for high quality coffee. Therefore, policies or projects related to coffee value chains should target improving farmers’ access to training, boosting the access to education, working on farmers’ productivity and increasing their technical knowhow on coffee certification to increase farmers’ participation in coffee certification and to improve their annual revenue earning level in the study area.

Published: May 2021

Abstract-Supplier selection is one of the important things in purchasing activities for companies. Supplier selection is a multi-criteria problem which includes quantitative and qualitative factors. One method that can be used for supplier selection is the AHP (Analytical Hierarchy Process) method. The problems that will be discussed in this study are: (1) how is the order of priority criteria and sub-criteria in the selection of suppliers at PT Garuda Hidrotive International? (2) which supplier / supplier should PT Garuda Hidrotive International choose based on the AHP method? The sampling technique uses judgment sampling because the AHP method requires dependence on a group of experts according to the types of specialists involved in decision making. Based on the results of the analysis, the advice that can be given is, if the company will develop a partnership with suppliers, the company is preferred to choose supplier X as a supplier food chemical for the company because supplier X is the best supplier that has the highest overall value. With this partnership, the supply chain performance between suppliers and companies will be better and can facilitate the overall production activities.

Authors: Zheng Shuai , Edwards Jonathan R , Dudeck Margaret A , Patel Prachi R , Wattenmaker Lauren , Mirza Muzna , Tejedor Sheri Chernetsky , Lemoine Kent , Benin Andrea L , Pollock Daniel A
Published: May 2021

Background

The Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network (NHSN) is the most widely used health care–associated infection (HAI) and antimicrobial use and resistance surveillance program in the United States. Over 37,000 health care facilities participate in the program and submit a large volume of surveillance data. These data are used by the facilities themselves, the CDC, and other agencies and organizations for a variety of purposes, including infection prevention, antimicrobial stewardship, and clinical quality measurement. Among the summary metrics made available by the NHSN are standardized infection ratios, which are used to identify HAI prevention needs and measure progress at the national, regional, state, and local levels.

Objective

To extend the use of geospatial methods and tools to NHSN data, and in turn to promote and inspire new uses of the rendered data for analysis and prevention purposes, we developed a web-enabled system that enables integrated visualization of HAI metrics and supporting data.

Methods

We leveraged geocoding and visualization technologies that are readily available and in current use to develop a web-enabled system designed to support visualization and interpretation of data submitted to the NHSN from geographically dispersed sites. The server–client model–based system enables users to access the application via a web browser.

Results

We integrated multiple data sets into a single-page dashboard designed to enable users to navigate across different HAI event types, choose specific health care facility or geographic locations for data displays, and scale across time units within identified periods. We launched the system for internal CDC use in January 2019.

Conclusions

CDC NHSN statisticians, data analysts, and subject matter experts identified opportunities to extend the use of geospatial methods and tools to NHSN data and provided the impetus to develop NHSNViz. The development effort proceeded iteratively, with the developer adding or enhancing functionality and including additional data sets in a series of prototype versions, each of which incorporated user feedback. The initial production version of NHSNViz provides a new geospatial analytic resource built in accordance with CDC user requirements and extensible to additional users and uses in subsequent versions.
Learning Clinical Procedures Through Internet Digital Objects: Experience of Undergraduate Students Across Clinical Faculties
Authors: Li Tse Yan , Gao Xiaoli , Wong Kin , Tse Christine Shuk Kwan , Chan Ying Yee
Published: May 2021

Background

Various digital learning objects (DLOs) are available via the World Wide Web, showing the flow of clinical procedures. It is unclear to what extent these freely accessible Internet DLOs facilitate or hamper students’ acquisition of clinical competence.

Objective

This study aimed to understand the experience of undergraduate students across clinical disciplines—medicine, dentistry, and nursing—in using openly accessible Internet DLOs, and to investigate the role of Internet DLOs in facilitating their clinical learning.

Methods

Mid-year and final-year groups were selected from each undergraduate clinical degree program of the University of Hong Kong—Bachelor of Medicine and Bachelor of Surgery (MBBS), Bachelor of Dental Surgery (BDS), and Bachelor of Nursing (BNurs). All students were invited to complete a questionnaire on their personal and educational backgrounds, and their experiences and views on using Internet DLOs in learning clinical procedures. The questionnaire design was informed by the findings of six focus groups.

Results

Among 439 respondents, 97.5% (428/439) learned a variety of clinical procedures through Internet DLOs. Most nursing students (107/122, 87.7%) learned preventive measures through Internet DLOs, with a lower percentage of medical students (99/215, 46.0%) and dental students (43/96, 45%) having learned them this way (both P<.001). Three-quarters (341/439, 77.7%) of students accessed DLOs through public search engines, whereas 93.2% (409/439) accessed them by watching YouTube videos. Students often shared DLOs with classmates (277/435, 63.7%), but rarely discussed them with teachers (54/436, 12.4%). The accuracy, usefulness, and importance of Internet DLOs were rated as 6.85 (SD 1.48), 7.27 (SD 1.53), and 7.13 (SD 1.72), respectively, out of a high score of 10.

Conclusions

Self-exploration of DLOs in the unrestricted Internet environment is extremely common among current e-generation learners and was regarded by students across clinical faculties as an important supplement to their formal learning in the planned curriculum. This trend calls for a transformation of the educator’s role from dispensing knowledge to guidance and support.
Patient Portal Use, Perceptions of Electronic Health Record Value, and Self-Rated Primary Care Quality Among Older Adults: Cross-sectional Survey (Preprint)
Authors: Cross Dori A , Levin Zachary , Raj Minakshi
Published: May 2021

BACKGROUND

Older adults are increasingly accessing information and communicating using patient-facing portals available through their providers’ electronic health record (EHR). Most theories of technology acceptance and use suggest that patients’ overall satisfaction with care should be independent of their chosen level of portal engagement. However, achieving expected benefits of portal use depends on demonstrated support from providers to meet these expectations. This is especially true among older adults, who may require more guidance. However, little is known about whether misalignment of expectations around technology-facilitated care is associated with lower perceptions of care quality.

OBJECTIVE

The aims of this study were to analyze whether older adults’ assessment of primary care quality differs across levels of patient portal engagement and whether perceptions of how well their provider uses the EHR to support care moderates this relationship.

METHODS

We conducted a cross-sectional survey analysis of 158 older adults over the age of 65 (average age 71.4 years) across Michigan using a 13-measure composite of self-assessed health care quality. Portal use was categorized as none, moderate (use of 1-3 functionalities), or extensive (use of 4-7 functionalities). EHR value perception was measured by asking respondents how they felt their doctor’s EHR use improved the patient–provider relationship.

RESULTS

Moderate portal users, compared to those who were extensive users, had lower estimated care quality (–0.214 on 4-point scale; P=.03). Differences between extensive portal users and nonportal users were not significant. Quality perception was only particularly low among moderate portal users with low EHR value perception; those with high EHR value perception rated quality similarly to other portal user groups.

CONCLUSIONS

Older adults who are moderate portal users are the least satisfied with their care, and the most sensitive to perceptions of how well their provider uses the EHR to support the relationship. Encouraging portal use without compromising perceptions of quality requires thinking beyond patient-focused education. Achieving value from use of patient-facing technologies with older adults is contingent upon matched organizational investments that support technology-enabled care delivery. Providers and staff need policies and practices that demonstrate technology adeptness. Older adults may need more tailored signaling and accommodation for technology to be maximally impactful.

The study investigated the pedagogical competence of teacher’s and its influence on student’s academic achievement. The descriptive survey research design was adopted and the census (all) sampling technique was used to sample 250 Junior High School (JHS) teachers in Ashaiman Municipality. The collected data from the close-ended questionnaire was analysed with mean and standard deviation on the scale of 1-4 and the Pearson’s Product Moment Correlation was used to test the hypothesis. The study revealed that as a pedagogical competence, the teachers provided appropriate feedback, adapted to changing conditions, explained content to students and communicated learning goals effectively. It was also found that there was a positive weak relationship between the classroom management competence of teachers and student’s academic achievement. The study, therefore, concluded that pedagogical competence of teachers could help promote deep knowledge, understanding and expectation among students if teacher’s pedagogical competencies are effective. Also, when teachers increase their knowledge and competence to manage the classroom, they could provide high expectations for student’s social support, guidance and independent thought in learning. Recommendations were made to the municipal education directorate, Ghana Education Service and Ministry of Education, Ghana based on the findings.

Ensuring the development of the agro-industrial sector at both the national and regional levels is a priority for Ukraine’s integration not only into the European but also into the global economic space. The purpose of the article is to study the trends and prospects for the development of the agro-industrial sector of the regions of Ukraine. In the research process, the methods of theoretical analysis, synthesis, observation, description, tabular-graphic, correlation analysis were used. According to the study results, the reduction of the share of agriculture, forestry and fisheries sector in the structure of the gross domestic product of Ukraine in the period 2015–2019 from 12.06% in 2015 to 8.97% in 2019 was established. The unstable dynamics of the agricultural index in Ukraine during 2015–2020 was determined, wherein 2019–2020, the decrease in the physical volume of agricultural production by farms of all categories was 6.8 and 12.9 relative points compared to previous years. There was revealed the growing dynamics of labour productivity at enterprises engaged in agricultural activities in 2015-2019, except for the year 2017, when there was a slight decrease in this indicator by 1.3%, compared to 2016. The results of the correlation analysis, aimed at determining the relationship between the key variables that characterize the development of the agro-industrial sector of Ukraine, showed that among the studied regions of Ukraine, a very high and high direct correlation was demonstrated by nine regions of Ukraine, among which the Lviv region became the leader. The proposed approach to applying correlation analysis between the volume of output and the expenses of all enterprises for the production (work, services) can be applied to other types of economic activity.Prospects for the development of the agro-industrial sector of the regions of Ukraine are seen in the following: 1) the creation of unique integration business networks through the implementation of cooperation mechanisms; 2) support for the implementation of export operations at the appropriate level and the development of the existing export support infrastructure, in particular at the regional level; 3) establishing cooperation between potential producers of raw materials and processors, efficient use of production capacity and innovative production of agro-industrial complex (AIC) with the use of technological innovations on this basis; 4) effective use and increase of resource potential, ensuring the economic stability of agro-industrial entities; 5) state support and stimulation of the agro-industrial complex; 6) reforming the scientific and technical sphere of the agro-industrial complex.

Penggalian kebutuhan sangat penting dilakukan dalam pengembangan perangkat lunak. Dengan melakukan penggalian kebutuhan yang lengkap dapat mengurangi masalah yang timbul pada saat aplikasi diluncurkan. Pada Sistem Informasi KRS UMM mahasiswa yang telah memilih kelas sering terjadi salah masuk kelas khususnya pada mata kuliah AIK, karena jadwal kelas yang dikeluarkan oleh sistem berbeda dengan jadwal dari pihak AIK. Oleh sebab itu penelitian ini bertujuan untuk melakukan analisis terkait sistem KRS yang ada dengan menggunakan metode persona. Persona merupakan salah satu Teknik yang dapat digunakan dalam penggalian kebutuhan dimana persona dilakukan untuk memperoleh informasi mengenai tingkah laku dan karakteristik dari user. Penerapan metode persona dalam penelitian ini bertujuan untuk mengetahui kebutuhan sistem dari sisi perspektif dari stakeholder terkait, dalam hal ini antara lain mahasiswa, prodi, infokom, dan AIK&MKDU.  Hasilnya dengan menggunakan Teknik persona, masing-masing dari primary persona (AIK&MKDU) dan secondary persona (Prodi Informatika) mengharapkan keselarasan antaran jadwal yang dikeluarkan oleh sistem KRS dan pihak AIK. Kemudian selanjutnya dilakukan pembuatan prototype berupa mock up usulan perbaikan dari system informasi KRS kushusnya pada mata kuliah AIK.  Penggunaan metode persona dirasa tepat untuk studi kasus ini, karena dengan menggunakan metode ini dapat mengetahui dari sudut pandang pengguna terkait apa saja sebenarnya yang dibutuhkan oleh system. Sehingga persona memungkinkan para pemangku kepentingan dan pengembang mendapatkan pemahaman yang lebih baik tentang kebutuhan dan perilaku pengguna target dan mengidentifikasi persyaratan yang hilang pada awal proses rekayasa persyaratan.

Published: May 2021

A partir de observações de campo, entrevistas informais e semiestruturadas realizadas entre 2018 e 2019, procurou-se neste artigo dar continuidade às reflexões em torno da trajetória da cidade balneária de Rio das Ostras (que foram iniciadas em 2015) no que tange as potencialidades transformadores da música em contribuir de forma significativa para desenvolvimento da localidade: inclusive, o governo municipal chegou a encaminhar em 2019 a candidatura dessa urbe como cidade criativa da UNESCO. Buscou-se analisar particularmente as articulações e tensões entre os atores, especialmente no momento em que a gestão pública ensaia valorizar a música como vetor de desenvolvimento socioeconômico, apostando na articulação desse tipo de expressão artística com a cadeia do turismo, gastronomia e, de modo geral, do entretenimento.

O objetivo deste estudo de recepção é compreender os modos de interpretação das relações de gênero por 24 mulheres da classe dominante de diferentes gerações a partir de telenovelas do horário nobre, no contexto brasileiro. As questões do estudo foram formuladas a partir dos relacionamentos amorosos e sexuais, presentes tanto no conteúdo veiculado quanto nas apropriações das informantes. Com aporte da Teoria das Mediações de Martín-Barbero, analisamos as leituras da telenovela pela audiência feminina a partir de suas experiências (sociabilidade). Os resultados obtidos indicam que a maioria das entrevistadas contesta os papéis tradicionais de gênero, mas têm dificuldade de admitir os comportamentos modernos para si, pois não conseguem realizá-los.

Analisa três vídeos da plataforma YouPorn selecionados a partir de buscas por “milf” e “amateur” (amador) e procede à análise cultural do material. Menciona sentidos possíveis das marcas culturalmente dispersas de corpo, feminilidade, maternidade e geração para caracterizar a milf. Tece considerações sobre aspectos da articulação entre pornografia e internet por meio do estímulo à visibilidade pela comunicação na internet como constituintes do consumo pornográfico online. Descreve e localiza a emergência da personagem pornográfica milf indicando que a personagem mulher, mãe, “mais velha” e “amadora” é uma justaposição particular de elementos mais amplos culturalmente, ligados às feminilidades e à heterossexualidade, articulados provisoriamente no interior da pornocultura midiática.
Microempreendedor individual e a noção de cidadania empresarial
Authors: Salgado Julia
Published: May 2021

Neste artigo, realizo uma análise de discursos midiáticos e institucionais sobre o microempreendedor individual (MEI) com o objetivo de pensar no conceito de cidadania empresarial, constantemente usado na promoção desta figura. Recorrendo a um referencial teórico proveniente sobretudo das ciências sociais e dos estudos culturais, reflito sobre as transformações do conceito de cidadania em um cenário neoliberal. Distanciando-se de uma concepção tradicional, segundo a qual a cidadania é pensada em termos coletivos e inclusivos, sugiro que a noção de cidadania empresarial se fundamenta sobre valores individualistas, recorrendo à noção de mérito para justificar seu restrito acesso.
Panthera Onca Corridors: A Spatially Explicit Analysis of Habitat Change Drivers and Potential Conservation Areas in the Bajo Magdalena, Colombia

The distribution range of Jaguar (Panthera onca) is being reduced due to multi-scale habitat conversion, intensive hunting, illegal trafficking, habitat fragmentation, and the construction of highways and other infrastructure. Because of the decrease in population, this species’ listing has changed from vulnerable to a threatened category. Due to the ecological importance of this species, organizations like Red Colombiana de Seguimiento de Fauna Atropellada have proposed the establishment of wildlife corridors. But little is known as to recognize the driving forces in these habitat changes and where these corridors should be established. To address this lack of information, we determined the spatial extent to which the current distribution and access to P. onca habitat is being driven by deforestation, armed conflict, agriculture expansion, urbanization and the construction of highways in the Bajo Magdalena area of Colombia. We then identified potential areas for proposing conservation corridors. To do this, we used available geospatial information on P. onca distribution in the Corporación Autónoma Regional areas in the municipalities of Puerto Salgar, Caparrapí and Guaduas, as well as transportation network, administrative unit, and deforestation data from 2010 to 2018. We also calculated habitat distances to population centers and the distribution of P. onca relative to roads. Our findings suggest that urban population and highways affect 83 % of the total area of its distribution; deforestation increased by 47.9 km2 in the 105.24 km2 study area with 5.6 km2 alone left as P. onca habitat. We concluded that conservation initiatives must be implemented inside P. onca’s distributional range and buffer zones. Urbanization and the construction of highways were highly influential variables associated with the loss of P. onca habitat. Further, we propose that precautions along the principal road that connects Puerto Salgar and Guaduas should be taken into consideration to maintain the genetic flow and movement of the P. onca population as it affects 87 km of this proposed corridor.
Apropiación social de la ciencia y la tecnología en Medellín: contribuciones al debate sobre su evaluación

Published: May 2021

Este artículo presenta resultados preliminares de una investigación orientada a definir, diseñar e implementar una evaluación de la apropiación social del conocimiento científico en un programa de educación no formal dirigido a niños, jóvenes, adultos y mediadores de ciencia. El texto se divide en cuatro partes: la primera muestra un breve estado de la discusión conceptual sobre el término de apropiación social del conocimiento y otros que se derivan de este; la segunda expone algunas formas de abordar la evaluación de actividades de apropiación social de la ciencia y la tecnología; la tercera presenta algunas reflexiones fruto de miradas locales sobre la conceptualización y evaluación de dicha apropiación en Medellín. Finalmente, se concluye que hay una tensión entre distintos actores relevantes para la apropiación social de la ciencia y tecnología en la ciudad de Medellín que se relaciona con diferencias conceptuales, tanto como con distintas formas de implementar actividades para fomentar y medir dicha apropiación. Así, es necesario reconocer un pluralismo conceptual en relación con los términos pertinentes para referirse a la relación entre ciencia y sociedad, así como reconocer una naciente comunidad académica enfocada a estos asuntos.
