Product Placement in Filipino Films: An approach to Consumer Purchasing Intention
Authors: Ong Camile Candi , Santiago Chris Joselle , Verdejo Coleen Kirk
Published: March 2022

Today, the majority of advertisements are digital, and the use of product placement is becoming an important tool for marketers. The use of this tool in the media, especially in films, is attractive to consumers and businesses. The consumer’s behavior towards product placement in films is evident in most countries; however, studies on local films such as in the Philippines are still limited in the literature. Drawing from the cognitive capacity theory, this study aims to examine the effect of Product Placements in Filipino films on the consumer's purchasing intention. From the online survey of (N=384) respondents exposed to local films that were released from the years 2009 to 2019, results reveal that the study put forward a significant effect on consumer behavior with a significant relationship between product placement and consumer purchasing intention. The study concludes that product placement in Filipino films affects consumers’ purchasing intention through brand recall, awareness, and attitude.

Prospectiva estratégica en el aula de clase
Authors: Mendoza Castro Martha Lucía
Published: March 2022

Como dijo Abraham Lincoln: “La filosofía del aula en una generación será la filosofía del gobierno en la siguiente”. En este mundo global reconocemos la realidad de este sentido filosófico, lo que exige a los científicos de este siglo a implantar de manera constante los procesos de formación en los estudiantes de diferentes programas, los proyectos integradores de aula, buscando así, el desarrollo de competencias a través del conocimiento significativo, que permite al estudiante explorar con la realidad, su entorno, comunidad, y lo vincula a la iniciación científica desde la investigación formativa, despertando el interés de los estudiantes en indagar lo desconocido y ser competentes en el área de estudio.

Hablar del proyecto integrador de aula es hablar de las competencias que aplica el estudiante Areandino en el aula de clase. La enseñanza tradicional se presenta en forma segmentada, se separan las disciplinas antes de reconocer sus solidaridades, se fragmentan los problemas más que vincularlos e integrarlos. Luego, se propone que la formación debe contemplar el abordaje de problemas que demandan comprensiones holísticas (como por ejemplo la pobreza, la contaminación ambiental, la violencia, los modelos de desarrollo, el desarrollo tecnológico, entre otros), donde se vinculen los intereses y saberes de los estudiantes con los conceptos, procedimientos, enfoques y propuestas propias de las disciplinas naturales y sociales al servicio de la comprensión de situaciones, relaciones y entornos propios de las diferentes áreas del conocimiento.

COMPARISON BETWEEN A REAL FIELD TRIP AND A VIRTUAL FIELD TRIP IN A NATURE PRESERVE: KNOWLEDGE GAINED IN BIOLOGY AND ECOLOGY
Authors: Puhek Miro , Perše Matej , Šorgo Andrej
Published: March 2022

The research presents a case study in the scope of which real and virtual field trips have been compared. The emphasis was on determining the levels of knowledge gain effectiveness in the fields of biology and ecology. A pre-existing natural trail in the protected area of Maribor Island was chosen and digitized for the purposes of the study. During the development of the virtual trail, real fieldwork was simulated in order to ensure a valid comparison. In the spring of 2011, field exercise tests were conducted by means of a study sample consisting of 211 (8th grade) lower secondary school students. The results have generally shown minute differences between the levels of knowledge acquisition effectiveness between both field trips. The results have also led to the conclusion that the students participating in the real field trip were more successful in their performance regarding the exercises they had been assigned, which included real objects serving as tools supporting the students in their observation and investigation endeavours. On the other hand, the students participating in the virtual field trip were more successful with regard to computer-assisted exercises, where they were able to access additional information on more complex processes. Key words: education, knowledge gain, lower secondary school, virtual field trip.
MAKING CONCEPT MAPS USEFUL FOR PHYSICS TEACHER EDUCATION: ANALYSIS OF EPISTEMIC CONTENT OF LINKS
Authors: Nousiainen Maija
Published: March 2022

In physics teacher education the use of graphical knowledge representation tools like concept maps are abundantly used because they are known to support the formation of organised knowledge. It is widely assumed that certain structural characteristics of concept maps can be connected to the usefulness of content. In order to study this relationship, the concept maps made by pre-service physics teachers are examined here. The design principles of the concept maps are based on quantitative experiments and modelling as the basic procedures in physics concept formation. The epistemic plausibility of justifications written in links is evaluated by using a four-level classification introduced here. The results show that the epistemic analysis of links affects remarkably to the acceptability of knowledge. The advantages of such concept mapping technique in supporting the conceptual understanding in physics teacher education are discussed as well as their usefulness in making plans for teaching.

Authors: Szyjka Sebastian , Mumba Frackson
Published: March 2022

This study re-evaluated the psychometric properties of the 40-item Inquiry Science Teaching Strategies instrument [ISTS] (Lazarowitz & Lee, 1976). The ISTS was administered to 201 elementary pre-service teachers at a university in the Midwest of United States during the 2009-2010 school terms. Initial CFA results failed to confirm the 3-factor structure of the original ISTS. A statistically significant goodness-of-fit statistic (χ² [737, N = 201] = 1394.61, p = 0.00) supported by two fit indices (GFI = 0.69, CFI = 0.45) indicated non-tenability of the measurement model. Subsequent PCA retained half of the components under an obliquely rotated 3-factor solution. Following the removal of 22 items, final CFA indicated non-tenability under slightly improved fitting (χ² [132, N = 201] = 236.93, p = 0.00, GFI = 0.88, CFI = 0.83). It is recommended that existing items be revised and new ones appended using Exploratory Factor Analysis with a different sample.

THE DIFFUSIONIST-EVOLUTIONIST MODEL OF E-LEARNING DEVELOPMENT
Authors: Jandric Petar
Published: March 2022

This paper explores development of the discipline of e-learning. It develops the evolutionist model of e-learning development and compares it with the diffusionist model of e-learning development. Using transdisciplinary research methodology, it develops the diffusionist-evolutionist model of e-learning development. The diffusionist aspect of the model concentrates to practical issues such as introducing e-learning into educational institutions. The evolutionist aspect of the model concentrates to theoretical issues such as comparative studies of historical developments. On such basis, the diffusionist-evolutionist model provides a single practical framework for describing small-scale and large-scale e-learning development. Following methodological restrictions, the diffusionist-evolutionist model does not reflect any natural principle. As a research principle, it only aims at improving our current descriptions of e-learning development.

How I diagnose and treat chronic myelomonocytic leukemia
Authors: Patnaik Mrinal M.
Published: March 2022

Chronic myelomonocytic leukemia (CMML) is a myelodysplastic syndrome/myeloproliferative overlap neoplasm characterized by sustained peripheral blood monocytosis and an inherent risk for transformation to acute myeloid leukemia (15-30% over 3-5 years). While CMML is morphologically classified into CMML-0, 1 and 2 based on peripheral blood and bone marrow promonocyte/blast counts, a more clinically relevant classification into dysplastic and proliferative subtypes, based on the presenting white blood cell count, is helpful in prognostication and therapeutics. CMML is a neoplasm associated with aging, occurring on the background of clonal hematopoiesis, with TET2 and SRSF2 mutations being early initiating events. The subsequent acquisitions of ASXL1, RUNX1, SF3B1 and DNMT3A mutations usually give rise to dysplastic CMML, while ASXL1, JAK2V617F and RAS pathway mutations give rise to proliferative CMML. Patients with proliferative CMML have a more aggressive course with higher rates of transformation to acute myeloid leukemia. Allogeneic stem cell transplant remains the only potential cure for CMML; however, given the advanced median age at presentation (73 years) and comorbidities, it is an option for only a few affected patients (10%). While DNA methyltransferase inhibitors are approved for the management of CMML, the overall response rates are 40-50%, with true complete remission rates of <20%. These agents seem to be particularly ineffective in proliferative CMML subtypes with RAS mutations, while the TET2mutant/ASXL1wildtype genotype seems to be the best predictor for responses. These agents epigenetically restore hematopoiesis in responding patients without altering mutational allele burdens and progression remains inevitable. Rationally derived personalized/targeted therapies with disease-modifying capabilities are much needed.

Published: March 2022

Water is essential for living organisms for their survival. Access of adequate and safe water is a basic need of human beings. In adequacy and unsafe water supply may cause various health problems. This study was designed with a view to assessing physicochemical properties of drinking water collected from different restaurants at Mymensingh sadar. In this case, electrical conductivity (EC), total dissolved solids (TDS), pH, dissolved oxygen (DO), biological oxygen demand (BOD), arsenic (As), iron (Fe) and lead (Pb) were measured. Furthermore, Microbiological assessments of drinking water samples were carried out. For achieving the microbiological assessment, methods of heterotrophic plate count (HPC) and total coliform count (TCC) were applied. The mean value of EC, TDS, pH, DO, BOD, As, Fe, Pb were 682.38 µS cm-1, 201ppm, 7.11, 4.98 mg/L, 1.72 mg/L, 0.005 ppm, 0.181 ppm and 0.000 ppm, respectively. According to the standard of drinking water the EC, TDS, pH, DO, BOD, As, Fe, Pb toxicity were not detected in all samples. All of above mentioned parameters were present in water within permissible limits. In most cases the concentrations of Pb and in some cases the concentrations of Fe were considered as toxicants due to the higher concentrations noted. The highest heterotrophic plate count was found in water of Ganginapar sample (1.2×107 CFU/ml) and the highest total coliform count was noted in C. K. Ghosh road sample (13 coliforms/100 ml). Therefore, the examined water quality parameters indicate that water quality of the restaurants at Mymensingh sadar is suitable for drinking. Although some of the samples identified as the presence of fecal coliforms that indicates contamination of feces with water. One sample among the studied drinking water samples was contaminated with fecal coliform which is very harmful for health and this water is not suitable for drinking. It may be concluded that hygienic and quality water need to supply for human drinking purposes.

Adipose tissue macrophages and atherogenesis – a synergy with cholesterolaemia
Authors: Poledne R , Králová Lesná I
Published: March 2022

Excessive LDL cholesterol concentration together with subclinical inflammation, in which macrophages play a central role, are linked pathologies. The process starts with the accumulation of macrophages in white adipose tissue and the switch of their polarization toward a pro-inflammatory phenotype. The proportion of pro-inflammatory macrophages in adipose tissue is related to the main risk predictors of cardiovascular disease. The cholesterol content of phospholipids of cell membranes seems to possess a crucial role in the regulation of membrane signal transduction and macrophage polarization. Also, different fatty acids of membrane phospholipids influence phenotypes of adipose tissue macrophages with saturated fatty acids stimulating pro-inflammatory whereas ω3 fatty acids anti-inflammatory changes. The inflammatory status of white adipose tissue, therefore, reflects not only adipose tissue volume but also adipose tissue macrophages feature. The beneficial dietary change leading to an atherogenic lipoprotein decrease may therefore synergically reduce adipose tissue driven inflammation.

Ankylosing spondylarthritis (AS) is associated falsely increased lumbar spine bone mineral density (BMD). New tool for discrimination of subjects at fracture risk is needed. Vertebral fracture (VF) prediction of routine methods for osteoporosis assessment, BMD and trabecular bone score (TBS), in patients with AS. Cross-sectional study of all AS patients regularly followed at the rheumatology outpatient clinics of two centers. All subjects undergone BMD measurement at lumbar spine (LS), total hip (TH) and femoral neck (FN) using Hologic® Horizon device. TBS at L1-4 in all subjects by TBS InSight® software were assessed. Vertebral fracture assessment (VFA) was performed using the lateral spine imaging IVA™ and graded using Genant semi-quantitative approach. 119 AS subjects (90 males/29 females), mean age 47.6 years were included in the study. In 20 patients 34 VFs were detected, from whom 7 patients had multiple fractures. Subjects with VF were older and had lower FN BMD, TBS in comparison to non-VF subjects. No differences in LS BMD, FN BMD or BASDAI between groups were observed. Among patients with VF only 3 had T-score less than -2.5 but 7 has TBS less than 1.23 which means highly degraded microarchitecture. AS patients with VF have lower TBS and FN BMD in comparison to non-VF subjects. In addition, TBS was able to detect 20 % more VFs than BMD. Therefore, TBS seems promising in VF discrimination among patients with AS.

Sarcopenia is defined as an age-associated loss of skeletal muscle function and muscle mass and is common in older adults. Sarcopenia as a disease is currently of interest not only to orthopedists and surgeons but also to internists, endocrinologists, rheumatologists, cardiologists, diabetologists, gynaecologists, geriatricians and paediatricians. In cooperation with the 5th Internal Medicine Clinic, we, as a unit of clinical research, aimed to describe a sarcopenic specific miRNA expression profile for disease diagnostics and classification of the severity of muscle performance deterioration. This study included a total of 80 patients (age 55-86 years) hospitalized at the V. Internal medicine clinic of LFUK and UNB with different severity of muscle performance deterioration. The study participants were evaluated and classified according to short physical performance battery score (SPPB). In this study, we investigated the role of circulating miRNAs in sarcopenia in the elderly. We hypothesized that sarcopenia effects the expression of muscle tissue-specific miRNAs (MyomiRNAs), which could be potentially reflected in the blood plasma miRNA expression profile. The expression of specific circulating miRNAs in patients with different muscle performances was analyzed. Patients’ blood plasma was evaluated for the expression of myomiRNAs: miRNA-29a, miRNA-29b, miRNA-1, miRNA-133a, miRNA-133b, miRNA-206, miRNA-208b and miRNA-499, and the data were correlated with diagnostic indicators of the disease. We showed a specific sarcopenia miRNA profile that could be considered a possible biomarker for the disease. Patients with low muscle performance showed increased miRNA-1, miRNA-29a and miRNA-29b expression and decreased for the miRNA-206, miRNA-133a, miRNA-133b, miRNA-208b and miRNA-499 expression. We show that the severity of muscle performance deterioration in sarcopenia correlates with specific miRNA expression. We also propose the profile of miRNAs expression in blood plasma as a specific biomarker for sarcopenia diagnostics. Future clinical studies will be necessary to eventually naturally have to elucidate the underlined molecular mechanism responsible for specific miRNAs expression in sarcopenia pathology and progression of the disease.

Recent studies show that many of the current and future careers involve some form of science, technology, engineering, and mathematics (STEM) integration. The new development of school STEM education provides opportunities for students to acquire the necessary knowledge, skills, and attitudes to face the challenges ahead. Involving students with different disabilities in STEM learning is of particular importance and usefulness because we should not deprive them of opportunities to engage in STEM fields in the future. However, how to expose students with intellectual disabilities (ID) to STEM learning have not been well explored. STEM learning can mean something different to each teacher, and how they integrate it into their classrooms may also differ. There are suggestions to use inquiry, engineering, and technology to support students with special needs. In the design of STEM learning for students who have ID, teachers from a special school constructed a 4E model of engaging, exploring, engineering, and explaining, which emphasizes inquiry and at the same time leverages technology and engineering to integrate learning content into a purposeful and informed way to improve student engagement in lessons. Lesson observations were conducted to study students’ cognitive, affective, and behavioral engagement in lessons. Results showed that students with mild ID in the classes responded and worked actively, while those with moderate ID asked for more assistance. Moreover, it was found that students were less involved in explaining. This research provides a practical model and evidence of student engagement in STEM learning.

In this quasi-experimental research, the effect of the inquiry-based 5E instruction on students’ learning of the topic of the main subatomic particles forming the atom as well as on their level of motivation was examined. The sample for the study comprised 45 ninth grade students enrolled in two randomly selected classes at a public high school located in a city center in the Aegean region, in the west of Turkey. The topic of main subatomic particles was taught to the experimental group students (n = 21) by inquiry-based 5E instruction, while the control group students (n = 24) were taught the topic using traditional instruction methods. The length of the study was 3 weeks. An academic achievement test which consisted of four open-ended questions and a chemistry motivation scale which was composed of 5-point Likert-type 30 items were administered to both groups as a pre-test and as a post-test. The data were analyzed using the independent-samples t-test and paired-samples t-test statistical analyses. The results showed that inquiry-based 5E instruction on the subatomic particles forming the atom has a significantly positive impact on academic achievement as compared to traditional instruction. Compared with traditional instruction, it was observed that using the inquiry-based 5E instruction did not produce a higher effect on student motivation. Based on the findings, this study provides suggestions that chemistry teachers, educators, and researchers can benefit from.
В.Г. Богораз как юкагировед

Published: March 2022

В статье рассматривается вклад В.Г. Богораза в изучение этногенеза, хозяйства, фольклора и духовной культуры юкагиров. Автор подчеркивает, что, хотя Владимир Германович специально не занимался изучением этого народа, он сделал ценные наблюдения, касающиеся взаимодействия юкагиров и чукчей, эвенов, русских старожилов, и нашел параллели в хозяйственной деятельности и культуре этих народов. Идеи ученого в области этногенеза и ранней этнической истории юкагиров в целом соответствуют современным представлениям, хотя о происхождении этого народа до сих пор идут дискуссии. В статье подчеркивается, что знаменитый труд В.Г. Богораза «Чукчи» вносит заметный вклад и в изучение этнографии юкагиров, их хозяйства и культуры конца XIX в.
In English:
The article highlights the contribution of V.G. Bogoraz to the study of ethnogenesis, economy, folklore and spiritual culture of the Yukagirs. The author shows that although V.G. Bogoraz did not specifically deal with the Yukagirs, he made and summarized many valuable observations on the interaction of the economy and culture of the Yukaghirs with the culture of the Chukchee, Evens, and Russian old-timers. The scientist’s ideas on ethnogenesis and the early ethnic history of the Yukagirs are generally consistent with modern ideas, although the problem of the origin of the Yukagirs has not yet been resolved. The ideas and observations of V.G. Bogoraz contained in his famous work “The Chukchee” (Russian translation of parts I-II, L., 1934, 1939) make a significant contribution to the study of the ethnography of the Yukagirs, of their economy and culture at the end of the 19th century.
Impact of Cropping System Diversification on Vegetative and Reproductive Characteristics of Waterhemp (Amaranthus tuberculatus)
Authors: Nguyen Huong T. X. , Liebman Matt
Published: March 2022

Corn- and soybean-dominated cropping systems create and maintain a favorable environment for summer annual weeds whose emergence and growth phenology are similar to these annual summer crops. Cropping system diversification can be an effective approach for controlling noxious weeds without increasing reliance on chemical herbicides. Diversification may be especially important for managing waterhemp, a dioecious, summer annual weed that is becoming increasingly prevalent in the US Corn Belt due to its life history characteristics and herbicide resistance profile. Compared to corn and soybean, alfalfa and oat emerge and establish earlier and are thus more competitive with warm-season weeds like waterhemp. Knowledge of vegetative and reproductive characteristics in a range of crop environments can be valuable for planning weed management strategies. However, most of the relevant characteristics for a population dynamics model were available in corn and soybean monocultures. We examined the relationship between waterhemp's aboveground mass and fecundity under four crop species' presence within three crop rotation systems: a 2-year sequence of corn and soybean; a 3-year sequence of corn, soybean, and oat intercropped with red clover; and a 4-year sequence of corn, soybean, oat intercropped with alfalfa, and alfalfa. All the rotation systems were treated with conventional or reduced rates of herbicides. We established eighteen linear equations to predict waterhemp's fecundity from dried aboveground mass in each crop and associated crop management program since measuring the latter allows for quicker estimation of fecundity compared to counting seeds on each individual plant. Rotation system and crop phase within rotation system had significant effects on all the response variables but weed control regime on some. The sex ratios at maturity were slightly female-biased in oat and alfalfa. Mature waterhemp plants were larger in corn and soybean than in oat and alfalfa. Oat and alfalfa were planted earlier than corn and soybean and successfully competed for resources against waterhemp despite the absence of herbicide or interrow cultivation. Frequent hay cuts in alfalfa served as physical weed control and contributed to suppressing waterhemp and other weeds substantially.
Multi-Stream Convolutional Neural Network-Based Wearable, Flexible Bionic Gesture Surface Muscle Feature Extraction and Recognition

Surface electromyographic (sEMG) signals are weak physiological electrical signals, which are highly susceptible to coupling external noise and cause major difficulties in signal acquisition and processing. The study of using sEMG signals to analyze human motion intention mainly involves data preprocessing, feature extraction, and model classification. Feature extraction is an extremely critical part; however, this often involves many manually designed features with specialized domain knowledge, so the experimenter will spend time and effort on feature extraction. To address this problem, deep learning methods that can automatically extract features are applied to the sEMG-based gesture recognition problem, drawing on the success of deep learning for image classification. In this paper, sEMG is captured using a wearable, flexible bionic device, which is simple to operate and highly secure. A multi-stream convolutional neural network algorithm is proposed to enhance the ability of sEMG to characterize hand actions in gesture recognition. The algorithm virtually augments the signal channels by reconstructing the sample structure of the sEMG to provide richer input information for gesture recognition. The methods for noise processing, active segment detection, and feature extraction are investigated, and a basic method for gesture recognition based on the combination of multichannel sEMG signals and inertial signals is proposed. Suitable filters are designed for the common noise in the signal. An improved moving average method based on the valve domain is used to reduce the segmentation error rate caused by the short resting signal time in continuous gesture signals. In this paper, three machine learning algorithms, K-nearest neighbor, linear discriminant method, and multi-stream convolutional neural network, are used for hand action classification experiments, and the effectiveness of the multi-stream convolutional neural network algorithm is demonstrated by comparison of the results. To improve the accuracy of hand action recognition, a final 10 gesture classification accuracy of up to 93.69% was obtained. The separability analysis showed significant differences in the signals of the two cognitive-behavioral tasks when the optimal electrode combination was used. A cross-subject analysis of the test set subjects illustrated that the average correct classification rate using the pervasive electrode combination could reach 93.18%.

COVID-19’s pandemic has hastened the expansion of online learning across all levels of education. Countries have pushed to expand their use of distant education and make it mandatory in view of the danger of being unable to resume face-to-face education. The most frequently reported disadvantages are technological challenges and the resulting inability to open the system. Prior to the pandemic, interest in distance learning was burgeoning, as it was a unique style of instruction. The mini-review aims to ascertain students’ attitudes about distant learning during COVID-19. To accomplish the objective, articles were retrieved from the ERIC database. We utilize the search phrases “Distance learning” AND “University” AND “COVID.” We compiled a list of 139 articles. We chose papers with “full text” and “peer reviewed only” sections. Following the exclusion, 58 articles persisted. Then, using content analysis, publications relating to students’ perspectives on distance learning were identified. There were 27 articles in the final list. Students’ perspectives on distant education are classified into four categories: perception and attitudes, advantages of distance learning, disadvantages of distance learning, and challenges for distance learning. In all studies, due of pandemic constraints, online data gathering methods were selected. Surveys and questionnaires were utilized as data collection tools. When students are asked to compare face-to-face and online learning techniques, they assert that online learning has the potential to compensate for any limitations caused by pandemic conditions. Students’ perspectives and degrees of satisfaction range widely, from good to negative. Distance learning is advantageous since it allows for learning at any time and from any location. Distance education benefits both accomplishment and learning. Staying at home is safer and less stressful for students during pandemics. Distance education contributes to a variety of physical and psychological health concerns, including fear, anxiety, stress, and attention problems. Many schools lack enough infrastructure as a result of the pandemic’s rapid transition to online schooling. Future researchers can study what kind of online education methods could be used to eliminate student concerns.

Introduction

Idiopathic premature adrenarche (IPA) is considered a normal variant of puberty, presenting more commonly in female patients. There are concerns as to whether IPA alters the final height of these girls. Our main objectives were to (a) compare the adult height of girls with IPA against their target height and (b) design a mathematical model to predict adult height at diagnosis in female patients with IPA.

Materials and Methods

A cohort study of girls with IPA was conducted from the time of IPA diagnosis until adult height. The following data were collected: target height, perinatal history, anthropometric and biochemical variables and bone age at diagnosis, age at Tanner stage 2 and menarcheal age, and adult height. First, we performed a univariate statistical analysis after which we carried out a multiple linear regression analysis using adult height as the dependent variable.

Results

We obtained data from 79 female patients diagnosed with IPA with a mean adult height of 164.6 cm (95% CI: 163.36–165.85 cm). The mean follow-up time was 6.60 years. Average age at Tanner stage 2 was 9.71 years. Mean menarcheal age was 11.64 years. There were no significant differences between target height and adult height. Of the several predictive models designed for these patients, one of them, which included bone age, obtained an R2 value of 71%.

Conclusions

Although slightly advanced puberty was observed among the girls with IPA, their adult height was preserved. The use of predictive models of adult height on diagnosis of IPA could facilitate closer follow-up of girls at risk of reduced adult height.

Since employing environmentally friendly technologies (EFTs) is a complicated and difficult process that is affected by multiple factors, researchers are encouraged to explore those influence factors. This research aims to estimate the households’ perception factors affecting the adoption intentions of EFTs. Based on a questionnaire survey from 782 Pakistani households, a structural equation modeling strategy yields empirical results. The main findings are: firstly, the drivers of adoption intention of EFTs include technological awareness, perceived environmental importance, perceived behavioral control, and perceived benefits. Secondly, significant barriers to the adoption intention of EFTs involve the perceived cost of EFTs and the perceived risk-averse behavior of households. Thirdly, among all factors, perceived environmental importance reveals the most substantial contribution, whereas perceived risk-averse behavior shows the least contribution to the adoption intention of EFTs. Finally, given these results, strengthening the financial benefits, controlling the roaring cost of EFTs, and the provision of rebates and subsidization are suggested to upscale the adoption intention of EFTs by the households.

Hurricanes have large and lasting effects along coastlines, representing one of the deadliest and costliest natural hazards. Among the rapidly growing literature on the impacts of hurricanes, an increasing topic of interest is the potential role of mangroves, and other coastal habitats, as nature-based strategies (NBS) for coastal defense. In addition to coastal protection, NBS have been shown to provide many ecological, economic, and social co-benefits. However, few studies have assessed coastal resident perceptions or residential-scale performance of NBS, particularly in the wake of major hurricanes. Through a survey of 288 residents of the Lower Florida Keys 1 year after Hurricane Irma, this paper describes hurricane impacts on mangroves, beaches, and hardened shorelines. Specifically, we measured perceptions of shoreline damage and shoreline effectiveness for coastal protection at the community- and parcel-levels. At the parcel scale, we also measured performance outcomes through the cost to repair or replace residential shorelines. At both community- and parcel-levels, beaches were perceived as the most damaged shoreline type, followed by mangroves, and then hardened shorelines as the least damaged. Specifically at the parcel-level, repair actions were not taken by many residents with a hardened shoreline (43.2%) due to their shoreline receiving no damage. However, when repair actions were taken, the average cost to repair or replace parcel-level mangroves ($64.33 (USD)±SE 58.08 per meter) was less than hardened shorelines ($105.14 (USD)±SE 38.57 per meter). Additionally, 44% of residents reported that no repair or recovery actions were needed after the storm for damaged mangroves, whereas when hardened structures were damaged, many required at least minor repairs (29.5%). Mangroves were also perceived as the most effective shoreline for storm protection (54%verytoextremely effective) at the community-level. Our findings indicate local community-level awareness of the storm protective properties mangroves provide but also display a disconnect between perceptions and performance outcomes at parcel scales. Although mangroves cost less to repair and are perceived as the most effective at storm protection, the majority of Florida Keys residents own hardened shorelines. Considering the diverse co-benefits mangroves provide and the local support mangroves have, their conservation and restoration could be well-supported for coastal adaptation.
China Revamping Decades-Old Fisheries Law to Combat Illegal, Unreported, and Unregulated Fishing: Stimulating the Intersection of Law, Technology, and Markets
Authors: He Juan , Zhang Xiong
Published: March 2022

As the world’s leading fish producer, exporter and consumer State, China must act decisively to eradicate national and international commerce in wild-capture species derived from illegal, unreported, and unregulated (IUU) fishing. In 2019 China launched an overhaul of its 1986 Fisheries Law with a draft statute subject to the deliberation of the National People’s Congress. In this policy brief, we argue that China should not miss the opportunity but proactively align with the global paradigm shift toward responsible and sustainable fisheries management. To amend the patchy legal framework and implement the rule of law ahead, we suggest technology-enabled traceability and market-responsive solutions to help the country mitigate illicit capturing, processing, and transaction events infiltrating from bait to plate.
