Digital technologies in music subjects on primary teacher training degrees in Spain: Teachers’ habits and profiles

Many recent proposals in music education relate to digital technologies. Technology can act as a mediator in the teaching-learning processes. Educators’ digital competence comprises the knowledge and skills in both instrumental and didactic use and methodological use that each teacher possesses. This work focuses on music education teachers at Spanish universities. It examines their knowledge of different digital resources, use of them to prepare classes, use of them in class and teaching of them, as well as considering how they learned to use these resources and any problems they encounter while teaching them. For this purpose, an ad hoc questionnaire was administered to a total of 93 teachers from 45 different universities. The results show superficial knowledge of technologies, limited use in class preparation, minimal use in class and almost non-existent teaching. They also reflect teaching staff who are largely self-taught and who complain of the limited resources available in the classroom.
Online Education in Social Work, Effectiveness, Benefits, and Challenges: A Scoping Review

ABSTRACT Online education has long been a controversial issue within the Australian social work community. Although technological advances have improved the quality of teaching substantially, scepticism and disbelief continue to exist. Despite the growing evidence base as to the effectiveness of online teaching, this tends to be overlooked. A scoping review of the literature was conducted to synthesise research conducted on online social work education to identify its effectiveness, potential, and challenges and to show whether online social work education will effectively prepare qualified social workers. This revealed that online education enhanced diversity and equity among social work students and students’ performances and satisfaction were similar for both online and on-campus students. Nevertheless, communication and engagement continue to be a challenge. IMPLICATIONS Decisions on online education should be based on evidence of effectiveness rather than on the assumption that face-to-face teaching is superior. Further research is needed to explore effectiveness of online education for different groups of students. Employers’ experiences with social work graduates from online courses need further research. Academics require support to tailor courses interactively and suitably for online education.
COMMUNITY STRUCTURE OF CHAETODONTIDAE IN THE WEST OF BANDA SEA

Distribution and composition of Indonesian Chaetodontid species may vary among different locations. However, illegal fishing practices such as bombing and poisoning on reef ecosystems have significant contribution to environmental degradation and can change the community structure of fish especially that of Chatodontids that act as indicator species in in the given areas. Therefore, it is important to do periodic surveys to know the current condition and their changing. A study on community structure of Chaetodontidae has been conducted from July to August 2011 on coral reef ecosystems of the Banda Sea and its adjacent waters including Banggai, Kendari, and Lamalera Islands. Scuba equipment was used and underwater visual census method was applied for collecting the data at 21 stations. A total of 1399 individual Chaetodontid fishes was observed, belonging to thirty species and seven genera, i.e. Chaetodon (20 species), Heniochus (4 species), Forcipiger (2 species), Chelmon (1 species), Coradion (1 species), Hemitaurichthys (1 species), and Parachaetodon (1 species). Chaetodon kleinii was the most dominant species in the Banggai (74,38%) and Lamalera (71,71%). Kendari was characterized by the presence of C. octofasciatus that contributed 55,20%. There were two dominant groups of Chaetodontidae based on the feeding guild. Facultative coral feeder was the most abundance in Banggai and Lamalera, while the most common Chaetodontidae in Kendari belonged to obligate coral feeder. Chaetodontid diversity in Banggai was the lowest compared to that of in other studied areas. Anthropogenic pressure may become a major factor causing the low diversity and studied species richness in the coral reef ecosystem of Banggai waters.
Effect of an accidental fire on Anastrepha fruit fly (Diptera: Tephritidae) community in a conservation area of the Cerrado Biome

Abstract. The effects of vegetation burning on populations and species composition of Anastrepha fruit flies in environments of the Cerrado are unknown. Thus, this study investigated the influence of fire on a community of fruit flies in two Cerrado environments, namely, typical Cerrado (savanna-like) and forested Cerrado. We collected species of Anastrepha , using McPhail traps weekly from 2 May 2011 to 30 April 2013. Collection data were analyzed using non-metric multidimensional scaling (NMDS) to characterize the patterns of variation in species composition, comparing the species abundance (numbers of individuals) before and after the fire event. The NMDS results showed an influence of both annual season and fire on the populations of fruit flies in the forested Cerrado, and a trend of population growth after the fire event in the typical Cerrado. The curves of species accumulation indicated a greater diversity of species in the post-fire than the pre-fire period, and the species diversity did not reach stabilization within the post-fire observation period. The diversity of habitats formed by burning and rapid regeneration of the flora after the fire could be responsible for the increase in species abundance and species richness of fruit flies in comparison with the pre-fire period. Efeito de um incendio acidental na comunidade de Anastrepha (Diptera: Tephritidae) em uma area de conservacao do Bioma de Cerrado Resumo. Os efeitos de queima da vegetacao sobre as populacoes e a composicao de especies de moscas das frutas do genero Anastrepha em ambientes do cerrado ainda sao desconhecidos. Assim, este estudo investigou a influencia do fogo em uma comunidade de moscas das frutas em dois ambientes de Cerrado: Cerrado tipico e Cerradao. Foram coletadas especies de Anastrepha , usando armadilhas McPhail semanalmente, no periodo de 2 maio de 2011 a 30 abril de 2013. Os dados das coletas foram analisados empregando-se escalonamento nao-metrico multidimensional (NMDS) para caracterizar os padroes de variacao na composicao de especies, comparando a abundância e diversidade das especies antes e apos o incendio. Os resultados NMDS mostraram uma influencia da epoca do ano e do fogo sobre as populacoes de moscas das frutas no Cerradao e uma tendencia de crescimento da populacao apos a passagem do fogo no Cerrado tipico. Curvas de acumulacao de especies indicaram uma maior diversidade de especies no periodo pos-fogo em comparacao ao periodo anterior ao incendio, e a diversidade de especies nao atingiu a estabilizacao dentro do periodo de observacao apos o incendio. A diversidade de habitats formados pela queimada e rapida regeneracao da flora apos tal incendio pode ter sido responsavel pelo aumento na abundância de individuos e riqueza de especies de Anastrepha em comparacao com o periodo anterior a passagem do fogo.
Rashomon in the Sahel: Conflict dynamics of security regionalism

The African Sahel is a region whose geopolitical dimensions are constantly changing and evolving as a result of new intersections of international, regional and local security dynamics. In this context, various actors have initiated different regional projects in an attempt to reframe the area according to their interests and specific interpretations of security and to impose the form of order that best fits with their goals. The discursive, normative and material struggle about the definition of the region is having obvious effects on security and conflict, furthering regional instability. This article disentangles the different region-building initiatives at work in the area by identifying the four groups of actors advancing a specific project around the Sahel, namely: (1) international security deliverers, (2) jihadist insurgent groups, (3) regional governmental elites, and (4) local communities and populations. In so doing, it explores how the different spatial and security imaginaries advanced by these four collective agents struggle and interact, and shows that the Sahel can be considered the unintended result of a competitive process that is furthering conflict and violence in a shifting regional security system.
Octopus insularis (Cephalopoda: Octopodidae) on the tropical coast of Brazil: where it lives and what it eats

is the dominant octopus in the shallow tropical waters of the coast and oceanic islands in the North and Northeast of Brazil. Is the abundance, distribution, habitat and diet of this species on the continent the same as in oceanic islands? These factors were evaluated in seeking these answers at two areas of occurrence of Octopus insularis on the coast of Rio Grande do Norte, Brazil. Three main types of habitats were described where the species is concentrated, being: Deep Reefs (Reefs of Risca) (> 15 m), Flat Biogenic Plateaus (Restingas) (5-15 m) and Shallow Sedimentary Reefs (Pirangi reefs) (< 5 m). An aggregate spatial distribution was verified, along with bathymetric segregation in which small individuals occupied shallow areas. Regarding diet,
Effects of Polarization Reversal on the Pitch Angle Scattering of Radiation Belt Electrons and Ring Current Protons by EMIC Waves

In this study, we investigate the effects of polarization reversal of electromagnetic ion cyclotron (EMIC) waves at the crossover frequencies on computations of bounce‐averaged pitch angle diffusion coefficients of radiation belt electrons and ring current protons. We find that inclusion of polarization reversal can cause significant changes of H+ band‐induced particle diffusion coefficients, while scattering by the He+ band is almost unaffected. Our results show that the pure L‐mode approach, which has been widely implemented in previous studies, tends to underestimate the diffusion coefficients of ultrarelativistic (>4 MeV) electrons and overestimate those of 10–50 and >100 keV protons caused by H+ band EMIC waves. Especially for >100 keV protons, the differences in diffusion coefficients can be larger by an order of magnitude. We confirm that the polarization reversal can contribute importantly to the scattering loss of radiation belt electrons and ring current protons by H+ band EMIC waves.
Period–luminosity–metallicity relation of classical Cepheids

Context. Classical Cepheids (DCEPs) are the most important primary indicators for the extragalactic distance scale. Establishing the dependence on metallicity of their period–luminosity and period–Wesenheit (PL and PW) relations has deep consequences for the estimate of the Hubble constant (H0). Aims. We investigate the dependence on metal abundance ([Fe/H]) of the PL and PW relations for Galactic DCEPs. Methods. We combined proprietary and literature photometric and spectroscopic data, gathering a total sample of 413 Galactic DCEPs (372 fundamental mode, DCEP_F, and 41 first-overtone, DCEP_1O) and constructed new metallicity-dependent PL and PW relations in the near-infrared adopting the astrometry-based luminosity. Results. We find indications that the slopes of the PL(KS) and PW(J, KS) relations for Galactic DCEPs might depend on metallicity on the basis of the comparison with the Large Magellanic Cloud relationships. Therefore we used a generalized form of the PL and PW relations to simultaneously take the metallicity dependence of the slope and intercept of these relations into account. Conclusions. We calculated PL and PW relations that for the first time explicitly include a metallicity dependence of the slope and intercept terms. The quality of the available data is insufficient, however, and we cannot yet present conclusive results, but they are relevant from a methodological point of view. The new relations are linked to the geometric measurement of the distance to the Large Magellanic Cloud and allowed us to estimate a Gaia DR2 parallax zero-point offset Δϖ = 0.0615 ± 0.004 mas from the dataset of DCEPs used in this work.
Deep Instance Segmentation of Laboratory Animals in Thermal Images

In this paper we focus on the role of deep instance segmentation of laboratory rodents in thermal images. Thermal imaging is very suitable to observe the behaviour of laboratory animals, especially in low light conditions. It is an non-intrusive method allowing to monitor the activity of animals and potentially observe some physiological changes expressed in dynamic thermal patterns. The analysis of the recorded sequence of thermal images requires smart algorithms for automatic processing of millions of thermal frames. Instance image segmentation allows to extract each animal from a frame and track its activity and thermal patterns. In this work, we adopted two instance segmentation algorithms, i.e., Mask R-CNN and TensorMask. Both methods in different configurations were applied to a set of thermal sequences, and both achieved high results. The best results were obtained for the TensorMask model, initially pre-trained on visible light images and finally trained on thermal images of rodents. The achieved mean average precision was above 90 percent, which proves that model pre-training on visible images can improve results of thermal image segmentation.
Comparative Seroprevalence and Risk Factors of Toxoplasmosis among Four Subgroups in Port Harcourt, Nigeria

Aims: This study was carried out to investigate the comparative seroprevalence and associated risk factors of toxoplasmosis among four subgroups in Port Harcourt viz: immunocompromised persons (HIV), pregnant women (PTW) and schizophrenics (SZN), using immunocompetent persons (IP) as controls. Study Design: A descriptive cross-sectional study was adopted. Place and Duration of Study: The study was carried out in the University of Port Harcourt Teaching Hospital (UPTH), Braithwaite Memorial Specialist Hospital (BMSH) and Neuro Psychiatric Hospital (NPH) between March 2016 and February 2017. Methodology: A total of 800 (200 from each of the group) samples were collected from subjects from the three hospitals. Study participants of ≥20 years were used in this study. The detection of T. gondii antibodies in examined sera was carried out using ELISA –IgG and IgM assay using standard procedures. Structured questionnaires were used to collect data on social demographic risk factors associated with toxoplasmosis. Original Research Article Orevaoghene and Wogu; MRJI, 30(7): 110-118, 2020; Article no.MRJI. 60236 111 Results: Out of the 800 (200 per group) examined, SZN recorded the highest seroprevalence of IgG 50%(100)(P.= .05) and IgM 4%(8) followed closely by HIV subjects with seroprevalence of IgG 32%(72) (P=.05) and IgM 2%(3). However, the seroprevalence were not significantly different from that of the immunocompetent control group which had the least seroprevalence. Schizophrenia subjects in age group 20-24 years recorded the highest seroprevalence with (P=.05) The unemployed recorded the highest seroprevalence for SZN with rates of 43% for IgG. More males were infected with the disease than females. Male Schizophrenics recorded a seroprevalence of 20.9%. There was no significant relationship between seroprevalence and demographic factors among subjects. Conclusion: Our findings indicated that toxoplasmosis was relatively prevalent (P=.05) among the studied population, with schizophrenics having the highest seroprevalence. Therefore, incorporating detection of anti-Toxoplasma antibodies in routine testing in our health care centers is recommended for monitoring and control of the disease.

Financial Returns to Household Inventory Management

Households tend to hold substantial amounts of non-financial assets in the form of inventory. Households can obtain significant financial returns from strategic shopping and optimally managing these inventories of consumer goods. In addition, they choose to maintain liquid savings – household working capital – not just for precautionary motives but also to support this inventory management. We demonstrate that households earn high returns from inventory management at low levels of inventory, though returns decline rapidly as inventory levels increase. We provide evidence using scanner and survey data that supports this conclusion. High returns from inventory management that are declining in wealth offer a new rationale for poorer households not to participate in risky financial markets, while wealthier households invest in both financial assets and working capital.
Professional satisfaction of physical education teachers

ABSTRACT The purpose of this paper was to explore the job satisfaction of physical education teachers. A descriptive-interpretative methodology was applied to data from a questionnaire aimed at primary and secondary school physical education teachers who work in public, state-funded and private schools in Spain. The contributions of self-determination theory as a framework for studying teacher job satisfaction have been the foundation for substantiating and interpreting the research findings. In this sense, we have taken into account the basic psychological needs and motivations of teachers as triggers for their professional satisfaction. In line with most of the research reviewed, feelings of competence for the job, decision-making autonomy as well as relational and psychological aspects seem to play a determinant role in the development of professional satisfaction. As a recommendation, we note that teacher satisfaction improves when there is full support by education administrators, high performance standards, appreciation for teaching work and collegiality among peers.
Populations of Pinus radiata D. Don differ in low-temperature tolerance and growth rate

Introduction: In Pinus radiata D. Don, one of the most widely planted pines globally, frost damages plantations at the seedling stage. Objective: To determine differences in growth and tolerance to low temperatures of native populations (Guadalupe and Cedros islands) of P. radiata in greenhouse and outdoors conditions, under different levels of soil moisture. Materials and methods: Low-temperature tolerance was determined through the damage index (DI) in freezing tests at -12 °C during 4 h. In each environment (greenhouse and outdoors) two soil moisture treatments were defined (irrigation and drought). The DI was evaluated with the method of electrical conductivity in primary needles during winter and spring. The absolute growth rate (AGR) of the terminal shoot was obtained by measuring the total height of the seedlings. Results and discussion: Average DI of 50 and 64 % were obtained in winter and spring, respectively. In greenhouse, DI was different (P ≤ 0.05) between populations, being higher in Guadalupe (>59 %) than in Cedros ( Conclusion: The population of Guadalupe is more sensitive to low temperatures with greater variation in DI, due to its growth dynamics. Differences between populations are useful in the genetic improvement of the species.
Theoretical and Empirical Advances in the Study and Control of White-Collar Offenders

Abstract Over the past decade the study of white-collar crime has been undergoing a resurgence of interest, productivity, and creativity. New findings have emerged regarding the social, demographic and psychological characteristics of white-collar offenders. These findings have spurred theoretical advances in the application of standard criminological perspectives to white-collar crime, including opportunity, life course, and informal social control theory. Researchers have also made advances in understanding how white-collar offenders are treated by the justice system and how they respond to that treatment, and these advances have implications for the prevention and control of white-collar crime. In this presentation, I review these theoretical and empirical advances and suggest avenues for future research and policy on this important and harmful form of criminal behavior.
Exploring the host-Guest interaction in tourism crisis communication

ABSTRACT The purpose of this study was to explore the host–guest interaction in tourism crisis communication. Guided by a practice-based approach, our study used the recent event of the 2018 Florida Red Tide as the context. It explored both visitors’ and residents’ information-acquiring and sharing practices in crisis communication. A total of 969 potential visitors and 460 Florida residents were surveyed, respectively. The findings of our study show that visitors preferred residents as their primary information sources in the crisis communication process. Repeat visitors who have no children and are the primary decision-maker are more likely to rely on residents for risk information than first-time visitors. The results further indicate that most respondents in the resident sample have shared Red Tide information with visitors through various channels. Knowledge and social identity influenced their information-sharing behaviour. The findings suggest that residents can act as risk insiders in tourism crisis communication. A new research direction involving the guest–host interaction in tourism crisis management is proposed. This study offers practical implications for promoting effective risk and crisis communication in destinations and incorporating residents in tourism crisis communication and management.
