Which activities do great-grandparents and great-grandchildren share in family contexts? An analysis of a new intergenerational relationship.

Título: ¿Qué comparten bisabuelos y bisnietos en contextos familiares? Análisis de una nueva relación intergeneracional Resumen: El objetivo general de este trabajo es conocer mejor el rol de bisabuelidad. Se entrevistó a un grupo de voluntarios con bisnietos (n = 78) mediante un cuestionario, cuyo contenido fue pilotado previamente, con preguntas sobre sus características sociodemográficas, las actividades que solían compartir con sus bisnietos y su opinión del rol de bisabuelidad, con la satisfacción asociada. Los datos fueron registrados y analizados tanto con tablas de frecuencia y estadísticos descriptivos, como con la prueba noparamétrica de Kruskal-Wallis. Los resultados obtenidos mostraron numerosas relaciones significativas entre las actividades compartidas y aspectos socio-demográficos de los bisabuelos como la edad (p ≤ .05), el nivel educativo (p ≤ .01), la salud (p ≤ .05), la distancia a la que viven de sus bisnietos (p ≤ .05). Además, de mostrar que perciben su rol de bisabuelidad en general como una continuidad del rol anterior de abuelidad, aunque desde una tipología intergeneracional formal, distinta a la tipología informal y, sobre todo, opuesta a la del rol sustituto/subrogado. La mayor satisfacción percibida estaba asociada a esa interacción típica del rol formal (p ≤ .01). Los bisabuelos podrían estar cumpliendo ya alguna función destacable en las familias actuales de cuatro generaciones. Palabras clave: Bisabuelos. Bisnietos. Roles familiares. Relaciones intergeneracionales. Percepción del rol. Abstract: The main aim of this study was to find out more about the role of great-grandparenthood. A group of participants with greatgrandchildren (n = 78) was interviewed using a questionnaire containing questions that had been put through a previous pilot study, covering participants’ sociodemographics, the activities that participants shared with their great-grandchildren, and their view of the role of great-grandparent and their related degree of satisfaction. The data were recorded and analyzed both with frequency tables and descriptive statistics and with the Kruskal-Wallis non-parametric test. The results showed several significant relationships between the shared activities and the sociodemographic variables, such as great-grandparents’ age (p ≤ .05), education (p ≤ .01), health status (p ≤ .05), the distance at which they live from their greatgrandchildren (p ≤ .05). Also, it was found that participants generally consider the role of great-grandparent to be a continuation of their prior role as grandparent, albeit from the perspective of a formal intergenerational typology, distinct from the informal typology and, above all, opposed to the role of substitute/surrogate. Greater perceived satisfaction was associated with this typical interaction of the formal role (p ≤ .01). Great-grandparents may already be fulfilling a notable function in today’s four-generation families.
Institutional investor heterogeneity and analyst recommendation: Malaysian evidence

Abstract This study investigates the association between institutional investors’ ownership and sell-side analysts’ stock recommendations in the context of the heterogeneous nature of institutional investors. Based on a sample of 281 Malaysian public listed companies over the period 2008–2013 (732 company-year observations), we find a significant positive relationship between institutional ownership, in particular ownership held by privately managed institutional investors and sell-side analysts’ stock recommendations, but no significant relationship between state owned institutional investors and sell-side analysts’ stock recommendations. This suggests that the relationship between institutional investors and analysts’ stock recommendations are different among different types of institutional investor. Our results are robust to tests for potential endogeneity between institutional ownership and analysts’ stock recommendations.
Twitch as a Techno-Pedagogical Resource to Complement the Flipped Learning Methodology in a Time of Academic Uncertainty

Flipped learning methodology has the potential to be combined with a multitude of didactic actions and techno-pedagogical resources that are adapted to the needs of the student. Access to resources and training outside the classroom can be carried out from various platforms. Following this line, Twitch is an interactive video transmission platform that is presented as an interesting digital resource to enhance the motivation of students in turning over learning moments. The objective of the study is to analyze the motivation of students in two different methodological approaches, one traditional and the other innovative through the Twitch application. A quasi-experimental pre-post design was carried out. A total of 52 Spanish students from the fourth level of secondary education participated in the research. Data collection was carried out by adapting the Motivated Strategies for Learning Questionnaire (MSLQ) instrument to the Spanish context. The results reflect higher levels of motivation in the implementation of Twitch with respect to its materialization without using said techno-pedagogical complement. This difference is especially significant in intrinsic motivation, since in the case of extrinsic motivation, the difference between both pedagogical proposals is smaller. In short, the implementation of Twitch in the flipped learning supposes an optimization of this pedagogical methodology, increasing the extrinsic and intrinsic motivation of the students and modifying the centers of interest of students from quantitative aspects to other, qualitative ones.
Advocating for Service-Learning as a pedagogical model in Physical Education: towards an activist and transformative approach

ABSTRACT Background There seems to be a need to rethink education and shape the future to build more equitable societies. In line with this idea, Service-Learning (SL) has emerged as an educational approach to integrate curricular learning and the provision of a community service. Unfortunately, many SL implementations in Physical Education lack a concrete frame of reference to guide them. Purpose Using the model-based practice framework, this paper aims to make the case to consider SL a pedagogical model to put transformative and socially critical Physical Education discourses into operation in real contexts. Method The article is structured around two main parts. Part 1 includes the criteria that any advocacy for a model should present within the models-based practice framework. Part 2 is divided into different subsections to introduce the theoretical foundations of SL, the major theme, the teaching implications and learning aspirations, exemplification of a particular case, and critical elements and benchmarks. It also contains a review of the research findings and reference networks and organizations that, despite not seeing SL specifically as a pedagogical model, report its development in Physical Education around the world. Results and implications In addition to setting the general bases and criteria to make the case for a pedagogical model, the paper addresses the main instructional implications for Physical Education: learning outcomes and teaching strategies. The work suggests that by considering the experiential, critical and transformative principles of the model, its major learning impact is upon the affective and social domains, in connection with the major theme identified: ‘learning by serving’. Another relevant contribution of the article is that it provides implementation guidelines through a 10-item checklist with benchmarks that typify SL’s key features. This checklist could be of value, since it can help practitioners and researchers to describe and verify future implementations. Conclusion SL has the necessary elements to be considered an activist, transformative, trans-domain and inter-contextual pedagogical model in Physical Education. Its dual major theme (learning by serving) uncovers new perspectives on teaching and learning in Physical Education, promoting the students’ social and affective domains. SL provides a connection between learning, teaching, content and context, requiring teachers and students to develop a commitment to the underlying philosophy of the model. Moreover, it occupies alternative spaces and locations to those traditionally used in Physical Education, and it can help develop genuine relationships between educators and students from schools and individuals and organizations from the community.
Identification and documentation of Ethno-veterinary remedies used by Afar Pastoralists for the treatment of Camel diseases in Ethiopia

Ethnoveterinary medicine is a scientific term for traditional animal health care that encompasses knowledge, belief, practice and skill of the community used for curing diseases and maintaining health of animals. A cross-sectional study was conducted using semi-structured questionnaires from September 2016 to August 2017 to gather information on the knowledge, practice and skill of the pastoralists and traditional healers about the importance and application of Ethnoveterinary medicine. Moreover, this study was conducted with the objectives of identification and documentation of major ethno-veterinary medicinal plants commonly used to treat camel aliments in Afar region. A total of 146 traditional healers and pastoralists were interviewed for baseline and reliable information about Ethno-veterinary medicinal practice in Afar region. Accordingly, 99.3% of the respondents were men in which 66.44% of them were in the age range of 45-60. Majorities (76.02%) of the information’s concerning EVM were obtained from the elders among which 84.93% responded that the overall EVM practice and status in pastoral society of Afar is decreasing. A total of 710 plant species supposed to have medicinal property were recommended by pastoralists to be used for the treatment of 49 different animal diseases. Among 64 plants specimen collected, Balanites aegyptia, Cissus rotundifolia (Forssk.) Vahl, Cadaba rotundifolia Forssk, Solanum sp, Acalypha indica L and Tamarix aphylla (L.) Karsts were the commonly used plant species with high fidelity value. Concerned with plant parts used, leaf (20.5%) was the most frequently used plant parts followed by root (19.4%), fruit (14.4%), seed (10.8%) and entire plant (8.8%). These herbal remedies were administered orally, nasally, ocular and topically. As a conclusion, pastoralists and traditional healers in Afar region have immense indigenous knowledge and practices of treating sick animals which should be supported by scientific techniques for analyzing the active ingredients contained in each plant species and for evaluating the safety, efficacy and dosage of the commonly used medicinal plants. In addition, on station establishment of commonly used medicinal plant nursery for conservation purpose and to conduct in-depth phytochemical analysis is paramount important.
Susceptibility of adult and larval stages of housefly, Musca domestica to entomopathogenic fungal biopesticides

ABSTRACT The current study assessed the efficacy of entomopathogenic fungal (EPF) biopesticides against adult and larval stages of houseflies, Musca domestica L. under laboratory conditions. Six commercial EPF biopesticides were selected for virulence tests; three strains of Beauveria bassiana (HF23 in the product balEnce™, GHA in the product Botanigard ES and ATCC 74040 in the product Naturalis-L), one strain of Metarhizium brunneum (F52 in the product Met52®), one strain of Lecanicillium muscarium (KV01 in the product Mycotal®), and one strain of Isaria fumosorosea (Apopka 97, in the product Preferal WG). Adult and larval stages of houseflies were sprayed with 2 ml of a conidial concentration (108 conidia ml−1) of each EPF biopesticide individually using a Potter tower. The results showed that balEnce™ and Botanigard ES were significantly the highest efficacy against adults and larvae of M. domestica, compared to other EPF biopesticides. The mean conidial concentration (LC50) for adults and larvae of M. domestica exposed to balEnce™ was 4.7 × 105 conidia ml−1 and 4.8 × 105 conidia ml−1 respectively, which was not significantly different from LC50 value of Botanigard ES (6.0 × 105 and 4.6 × 105 conidia ml−1). The mean lethal time (LT50) values of balEnce™ and Botanigard ES were significantly shorter at 109 and 108 than other conidial concentrations. balEnce™ or Botanigard ES caused 44–94% reduction in daily fecundity of the adult females from day 3 to day 10 post-treatment. Results demonstrated that EPF biopesticides balEnce™ and Botanigard ES have potential as biocontrol agents of M. domestica but further research under operational conditions is required.
Enhanced Electrochemical Performances of Hollow-Structured N-Doped Carbon Derived from a Zeolitic Imidazole Framework (ZIF-8) Coated by Polydopamine as an Anode for Lithium-Ion Batteries

Doping heteroatoms such as nitrogen (N) and boron (B) into the framework of carbon materials is one of the most efficient methods to improve the electrical performance of carbon-based electrodes. In this study, N-doped carbon has been facilely synthesized using a ZIF-8/polydopamine precursor. The polyhedral structure of ZIF-8 and the effective surface-coating capability of dopamine enabled the formation of N-doped carbon with a hollow structure. The ZIF-8 polyhedron served as a sacrificial template for hollow structures, and dopamine participated as a donor of the nitrogen element. When compared to ZIF-8-derived carbon, the HSNC electrode showed an improved reversible capacity of approximately 1398 mAh·g−1 after 100 cycles, with excellent cycling retention at a voltage range of 0.01 to 3.0 V using a current density of 0.1 A·g−1.
Built environment attributes and their influence on walkability

Abstract Walking is a sustainable mode of transport and a healthy way of doing physical activity. Walkability is a concept that has gained enormous popularity in recent years due to its potential to promote more sustainable urban environments and healthy lifestyles. This paper provides a literature review to analyze the influence of built environment attributes on walkability. The Scopus and Web of Science databases were chosen to survey the peer-reviewed documents published up to June 2020. A total of 132 documents were selected by the search. The review of these 132 documents showed that various built environment attributes were differently analyzed and assessed. More specifically, the search identified 32 built environment attributes that were assessed by using 63 measures. Intersection density, residential density and land use mix were the most used attributes for assessing walkability, namely by using objective methods, such as ratios and spatial score tools. In turn, attributes related to streetscape design and security were much less adopted in walkability assessments. This paper provides additional insights into how built environment attributes influence walkability and identifies gaps and issues that should be analyzed in-depth in the future. The review could be helpful for researchers and urban planners in developing walkability studies and in defining policies to improve walkability.

A Strings-Based Similarity Analysis Approach for Characterizing IoT Malware and Inferring Their Underlying Relationships

Mitigating threats associated with the rise of Internet-of-Things (IoT) malware requires creating a better understanding about the characteristics and inter-relations of IoT malware. In this letter, we perform a large-scale characterization of IoT malware. The analysis of 70,000 recently detected malware executables indicate that they belong to a few known families. Additionally, we highlight the lack of sophisticated IoT malware binary obfuscation. Thus, enabling reverse-engineering and static malware analysis, while performing a multi-level strings-based analysis to uncover groups of correlated IoT malware with common characteristics/features (e.g., adversarial IP addresses and malware-specific strings). Moreover, while our findings indicate malicious implementation reuse, we illustrate the rapid IoT malware evolution by identifying covid-related malware samples. Finally, this work provides a basis for developing AI-based malware detection/mitigation models, which benefit from the simplicity and reliability of the extracted strings-based characteristics/features for effective IoT malware classification and family attribution.
Effect of leaf extract of Lantana camara with Maize-based coating on the quality of fresh-cut fruits of Ananas comosus and Musa acuminata

Abstract Fresh-cut fruits of Ananas comosus (pineapple) and Musa acuminata (banana) have a relatively short shelf-life hence the need to enhance their quality. Preservation effect of ethanolic extract of leaf of Lantana camara (10%w/ v) incorporated with maize-based edible coating on fresh-cut fruits of banana and pineapple were determined. To achieve the objective of this study, the pH, total carotenoid content, ascorbic acid, total phenolic content, fungal load, antioxidant activity, total soluble solids, and browning potential of coated fruits at ambient temperature (PEC); untreated fruits (NTS), sodium benzoates (BSB) at ambient temperature and a coated sample (PEC@4) at 4°C were analysed at intervals for 15 days. The quantitative phytochemical constituents of the extracts were assayed. The phytochemical analysis of the extract shows high yields of tannins, flavonoids, anthraquinones, and low yields of alkaloids and cardiac glycosides. The quality assessment of the test fresh-cut fruits revealed that there was higher preservation activity in PEC@4 of banana and pineapple, followed by a considerable efficacy of PEC of banana and pineapple. This study shows the great potential of the extract of L. camara for the preservation of Ananas comosus and Musa acuminata, with incorporation of maize-based coating as the carrier of its functional property.
The Fractal Scaling Relationship for River Inlets to Lakes

Scaling relationships provide simple rules for understanding complex hydrographic patterns. Globally, river inlet abundance varies among lakes by about three orders of magnitude, but few scaling relationships describe this aspect of lake‐river connectivity. In this study, we describe a simple theoretical scaling relationship between lake surface area and river inlet abundance, and test this theory using data from Scandinavia. On average, the number of inlets increases by 67% for each doubling of lake area. However, lakes of vastly different areas can have the same number of inlets with relatively small variations of drainage density, lake shape, or junction angle ‐ characteristics that can often be linked to specific geological processes. Our approach bridges the gap between the detailed understanding of geomorphic processes and large‐scale statistical relationships, and engenders predictions about additional patterns including the relationship between lake area and water residence time.
Dependence of Rural Communities on Unsafe Water Sources - Case study of Tinda Village, Northeastern Nigeria

Accessibility of rural dwellers, particularly in Northern Nigeria, to basic water services has been a significant challenge over the years, thereby contributing significantly to the high mortality rates associated with waterborne disease recorded in the region. Recent information is required about the state of water facilities in some of these marginalized communities to proffer sustainable solutions. This community-based survey explored the water services available to rural dwellers in Tinda village, Gombe State. Data was collected via participant and community observation. Grab water samples were also obtained and analyzed for physicochemical and bacteriological parameters using standard methods. The village lacked an improved drinking water source. The major source present was a dam, while other sources available were a river and an unsanitary well. The surface water samples were turbid and coloured, while the well water was slightly turbid and coloured. The lead, iron, and manganese levels of the surface water samples were above Original Research Article Wada et al.; IJECC, 11(2): 76-87, 2021; Article no.IJECC. 67467 77 WHO permissible limits. E.coli was detected in both the river and well water samples, while salmonella sp. was detected in all the water sources. Disinfection of the water samples with a water guard (local chlorine disinfectant) significantly reduced the microbial load. However, the water was still unsafe for drinking. The current state of water facilities in Tinda village is deplorable. With the primary water sources polluted with both heavy metals and microbes, the health of rural dwellers remains at stake.
Preclinical study of peripheral nerve regeneration using nerve guidance conduits based on polyhydroxyalkanaotes

Abstract Nerve guidance conduits (NGCs) are used as an alternative to the “gold standard” nerve autografting, preventing the need for surgical intervention required to harvest autologous nerves. However, the regeneration outcomes achieved with the current NGCs are only comparable with autografting when the gap is short (less than 10 mm). In the present study, we have developed NGCs made from a blend of polyhydroxyalkanoates, a family of natural resorbable polymers. Hollow NGCs made from a 75:25 poly(3‐hydroxyoctanoate)/poly(3‐hydroxybutyrate) blend (PHA‐NGCs) were manufactured using dip‐molding. These PHA‐NGCs showed appropriate flexibility for peripheral nerve regeneration. In vitro cell studies performed using RT4‐D6P2T rat Schwann cell line confirmed that the material is capable of sustaining cell proliferation and adhesion. PHA‐NGCs were then implanted in vivo to repair 10 mm gaps of the median nerve of female Wistar rats for 12 weeks. Functional evaluation of the regenerated nerve using the grasping test showed that PHA‐NGCs displayed similar motor recovery as the autograft, starting from week 7. Additionally, nerve cross‐sectional area, density and number of myelinated cells, as well as axon diameter, fiber diameter, myelin thickness and g‐ratio obtained using the PHA‐NGCs were found comparable to an autograft. This preclinical data confirmed that the PHA‐NGCs are indeed highly promising candidates for peripheral nerve regeneration.
