Exploring Organisational Commitment of Teachers in Barbados and the Eastern Caribbean
Authors: Marshall Ian , Maynard Donna-Maria , Jules Mia
Published: May 2023

Research has established a relationship between the organisational commitment of teachers and some key teaching-career related variables. However, there has not been any exploration of organisational commitment in Eastern Caribbean schools. Using a cross-sectional research design, we surveyed a sample of 158 teachers to investigate relationships between organisational commitment and selected variables (i.e., career advancement opportunities, principal leadership style, teaching experience, and training). Findings revealed that primary school teachers reported higher levels of organisational commitment than secondary school teachers. However, no significant differences were found in the organisational commitment of trained and untrained teachers, nor were any found between organisational commitment and the other teaching career-related variables included in the study. We discuss the nuanced nature of organisational commitment in schools in Barbados and the Eastern Caribbean that lend to critical policy initiatives.

Published: May 2023

Several studies have been carried out related to the analysis of the relationship with respect to the dynamic properties of f and its hyperextension ̄f. However, the literature regarding the analysis of the effects of individual and collective chaos on their behaviour is scarce. Therefore, in this article several conjectures and questions are established according to the affectation of individual chaos in an ecosystem and its chaotic behaviour within the dynamics of this ecosystem, but as a whole. Thus, in the first instance, an introduction to the conceptualization of topological transitivity, chaos in the Devaney sense and how they are specified in continuous linear operators arranged in a Fréchet space (hypercyclic operators) will be established. In addition, the different notions of chaos that can occur depending on the relationship of the function, and its hyperextension will be described, to finally corroborate the present chaos with greater force than Devaney’saccording to the strong periodic specification property, the same one that applies to both f and a ̄f with the purpose of verifying the directionality in which individual and collective chaos can occur.

Published: May 2023

The social challenges of modern globalization caused by the COVID-19 pandemic have led to significant changes in the development of economic systems at various levels. Social development in the direction of a post-industrial society activates the introduction of digital technologies in all areas of life, which requires paying attention not only to the innovative component of its development, but also to the intellectual one, since the digital transformation requires a constant updating of knowledge; this determines the purpose of this scientific study. The article aims to highlight the influence of intellectual and innovative determinants in the development of regions under current conditions, which are outlined by the manifestations of the COVID-19 pandemic and global digitalization in the development of economic systems. The foundation of the system approach methodology made it possible to distinguish the development trends of the regions in the conditions of the COVID-19 pandemic and global digitalization. It is proposed to create guidelines for the intellectual and innovative promotion, determinants of the development of the regions in the conditions of the COVID-19 pandemic and global digitalization, according to the socioeconomic, scientific-technological, organizational and legal components. The main guidelines of efforts to increase the role of intellectual and innovative determinants in the development of regional systems in the conditions of the COVID-19 pandemic and global digitalization have been tested, taking into account the principles of complexity, integrity, flexibility, efficiency and long term.

Measuring Changes in Chinese Banking Productivity and Profitability
Authors: Liu Li-Lun , Wang Mu-Shun , Su Yao-Jen
Published: May 2023

Abstract

This paper adopts the Hicks-Moorstein (HM) TFP index and Data Envelopment Analysis (DEA) to explore efficiency and its relation to changes in profitability and productivity in Chinese commercial banks (CBs). We decompose the HM TFP index into changes in technology, pure technical efficiency, scale efficiency, and output mix and then test for distribution differences when comparing the Malmquist and Hicks-Moorstein productivity indices for a given type of data. The study results reveal that the CBs experience primarily an increment of mix-efficiency rather than an improvement in pure technical efficiency (improvement in management practices) and that Chinese CBs pursue technological progress to meet the requirements for financial innovation and internet banking. This paper highlights the importance of analyzing performance from multiple perspectives and provides alternative explanations of improving productivity and profitability based on technical efficiency in general. Our results indicate that including non-performing loans as the input increases the efficiency score, but off-balance sheet items do not have a significant impact.

Small-scale population structure of eastern North Pacific harbour porpoises (Phocoena phocoena) indicated by molecular genetic analyses
Authors: Chivers S. J. , Dizon A. E. , Gearin P. J. , Robertson K. M.
Published: May 2023

Concern about the conservation and management of harbour porpoise (Phocoena phocoena) populations, which have experienced relatively large incidental fishery kills in localised areas throughout their range, has prompted research to better understand their population structure. Both mitochondrial and nuclear (microsatellites) DNA were used to examine the intra-specific structure of harbour porpoise inhabiting the eastern North Pacific Ocean. Null hypotheses of panmixia were tested after mitochondrial DNA (mtDNA) control region sequence data (402 base pairs; n = 249) and allele frequency data (9 polymorphic loci; n = 194) were sub-divided into geographic strata defined a priori. Strata were based on sampling discontinuities and not discontinuities in population distribution. The mtDNA and nuclear gene data revealed statistically significant genetic differentiation between most strata (a = 0.05) suggesting demographic independence of fairly small sub-units within the population. Since harbour porpoises are essentially continuously distributed in the eastern North Pacific, this degree of genetic differentiation was unexpected and needs to be considered in developing a sound management plan to protect them.
A blue whale (Balaenoptera musculus) feeding ground in a southern Australian coastal upwelling zone
Authors: Gill Peter C.
Published: May 2023

A localised aggregation of blue whales, which may be pygmy blue whales (B. m. brevicauda), occurs in southern Australian coastal waters (between 139°45AE-143°E) during summer and autumn (December-May), where they feed on coastal krill (Nyctiphanes australis), a species which often forms surface swarms. While the abundance of blue whales using this area is unknown, up to 32 blue whales have been sighted in individual aerial surveys. Krill appear to aggregate in response to enhanced productivity resulting from the summer-autumn wind-forced Bonney Coast upwelling along the continental shelf. During the upwelling’s quiescent (winter-spring) period, blue whales appear to be absent from the region. Krill surface swarms have been associated with 48% of 261 blue whale sightings since 1998, with direct evidence of feeding observed in 36% of all sightings. Mean blue whale group size was 1.55 (SD = 0.839), with all size classes represented including calves. This seasonally predictable upwelling system is evidently a regular feeding ground for blue whales, and careful management of human activities is required there.
A note on a computer-based system for theodolite tracking of cetaceans
Authors: Gailey Glenn , Ortega-Ortiz Joel G.
Published: May 2023

Theodolites represent a non-invasive shore-based tool for obtaining data on cetacean movement patterns, habitat use and behavioural disturbance. Despite the common use of theodolites as research tools, relatively few computer-based systems exist to assist researchers with collection of theodolite derived data and the analysis of such information. A recently developed computer program named ‘Pythagoras’, provides an efficient and user-friendly tool for collecting, managing and subsequent analysis of data obtained with theodolites. Pythagoras provides location of user-defined fix types (e.g. whales, dolphins, boats, etc.) and has a dynamic interface, that can be customised to fit site-specific research needs. Additional information (behaviour, group size and environmental conditions) can be stored with each theodolite fix. Tracking data are immediately available in the form of a real-time graphic representation. All collected data are stored in Microsoft Access and can be exported as Microsoft Excel, ArcInfo, Surfer, MATLAB, or delimited text file formats. An analysis module is included to calculate linearity, reorientation rate and leg speed for each track, and distance and orientation between two or more tracklines. Behavioural data are analysed for frequency, time intervals (i.e. blow interval), duration (i.e. surface time) and rate (number per minute) of particular behaviours. Several other computer-based theodolite systems are reviewed here to evaluate their potential benefits and limitations as a means of providing a basis for future developments.

Authors: Kalengay Mbela , Paulus Kaarina , Mutanga Marcus
Published: May 2023

The coming of the COVID-19 has pushed many teaching institutions to shift from face-to-face teaching mode to online mode. Practical sciences activities for undergraduate students in the field of Integrated Natural Sciences at the University of Namibia Rundu Campus have been disrupted to adapt to the sudden changes. The focus of this study was to examine students’ experiences on practical distanced methods used such as in-lab sessions, remote access to in-lab equipment, take-home kits, and other online methods. A qualitative approach was adopted to generate data through semi-structured interviews, focus group interviews and narratives. The participants were 30 students in third and fourth year from science department due to the experience they had on both face to face and online practical activities. The researchers used the narrative approach for the participants to give voice and elaborate on their own experiences. The results showed that although students enjoyed working from home, the shift to online sciences laboratory activities is still a challenge to our capacities and boundaries of our collective knowledge, understanding and practices.

Published: May 2023

The term “social media” refers to a group of online communication platforms that focus on user-generated content, collaboration, and community involvement. This review’s main objective is to give detailed information regarding how social media affects society. Several researches suggested that social media might have both positive and positive effects. Positive results include improved learning opportunities, socialization and communication, as well as access to health-related information. Some of the negative effects of social media on societies include terrorism, criminal activity, catfishing, depression, anxiety, and catfishing. The outcome will typically be favorable when people utilize social media for the right reasons and set goals, and the opposite is true for bad side effects.

Hardscape of Soil Surface Surrounding Urban Trees Alters Stem Carbon Dioxide Efflux
Authors: Marler Thomas E.
Published: May 2023

The diel patterns of stem carbon dioxide efflux (Es) were quantified for 8 lignophyte tree species using paired trees, with one tree surrounded by hardscape from the bole to the canopy perimeter and the second tree surrounded by grass or mulch. StemEswas measured at a height of 30 to 40 cm on the boles, and measurements were made about every 2 hours during 31-hour measurement campaigns. NocturnalEswas similar for the hardscape trees and the trees without hardscape. Trees surrounded by hardscape exhibited daytimeEsthat was 73% greater than nocturnalEs. In contrast, trees surrounded by grass or mulch exhibited daytimeEsthat was only 55% greater than nocturnalEs. The diurnal maximum ofEswas in the morning for trees surrounded by hardscape but was in the afternoon for trees growing in grass or mulch. The results indicated root-respired carbon dioxide was transferred to the bole through daytime transpiration, and more of this carbon dioxide was released from the bole surfaces for trees surrounded by hardscape.

Published: May 2023

The purpose of the study was to identify the interaction of step characteristics, along with the direction and magnitude of their asymmetry of elite male and female pole vaulters between successful and failed attempts. It was hypothesized that step characteristics and the magnitude of asymmetry between the two legs would interact with the outcome of the attempt. The approach runs of 12 pole vaulters (7 males, 5 females) were recorded during an indoor international competition. The leg used by the athlete for taking-off was defined as the non-pole-carrying leg, while the other was the pole-carrying leg. Using spatiotemporal information obtained from recordings with a panning camera (300 fps), the last steps of each athlete's approach run were analyzed for length, frequency, average velocity, and inter-limb asymmetry. There was no inter-limb difference (p > 0.05) in the absolute values of step length or step velocity between successful and failed attempts. However, the pole-carrying leg presented significantly (p < 0.05) higher step frequency values at the failed attempts. There was no significant difference (p > 0.05) in asymmetry values for step length, frequency, and average velocity between successful and failed attempts. Although step velocity remained unaffected, failed attempts were characterized by a perturbation in the interaction of step frequency and step length. The present findings suggest that although high velocity at the final phase of the approach is essential, it is not the sole determining factor for a successful attempt.

Published: May 2023

Anterior cruciate ligament injuries (ACLIs) are one of the most common knee injuries in sports. Although numerous factors have been related to the risk of ACLIs, it is still unclear why some individuals are more susceptible than others due to the intricate etiology of ACLIs. Several genetic factors have been identified as contributing to ACLIs. This systematic review summarizes the current evidence regarding the genetic causes of ACLIs based on the available literature. Five electronic databases were searched from 2017 to 2022. All titles, abstracts, and full texts were reviewed in detail to determine the inclusions and exclusions. The Newcastle-Ottawa Scale was used to evaluate the risk of bias.
The studies' characteristics and results are presented in both narrative and tabular formats. A total of 24 studies examined 31 genes and 62 variants associated with ACLIs in the global population. Ten studies investigated seven collagens and ten SNPs for the ACL injury. The majority of studies found no significant difference in the association of the COL1A1 rs1800012, COL5A1 rs12722, VEGFA rs1570360, IL6R rs2228145, IL6 rs1800795, IL1B rs16944 and rs1143627, however, contrary results were found when nationality and gender were considered together. Conflicting evidence was found for polymorphisms rs2010963, rs699947 of the VEGFA gene in different studies. Due to a lack of data, it was impossible to determine the relationship between the anterior cruciate ligament rupture (ACLR) and the other polymorphisms. More research is required to establish a clear relationship between the ACLR and genetic variants, particularly when gender and nationality are taken into account separately.

Published: May 2023

Recent books about evaluations to study the quantitative impact of development programs and projects typically devote a chapter or two of the need to complement the analysis with other methods – specifically qualitative techniques. They often cite how qualitative techniques help explain the reason for positive or negative quantitative results. This is key if the one is to draw conclusions for accountability or for learning to improve future program design. Or they explain how qualitative work is critical to make sure that quantitative data are collected in the right way. Despite these textbook recommendations, there has been a wide range of experiences in how using both quantitative and qualitative methods have affected the overall quality of evaluations. In many cases, the qualitative analysis consists mostly of quotes to justify findings from the quantitative work. While this helps provide context, there is not much value-added beyond making the an otherwise ‘dry’ quantitative presentation more interesting. Some recent evaluations have begun to change this practice and have arguably improved the quality of impact evaluations in terms of their relevance, the inferences that are drawn from them and their applicability to policymakers and programme implementers. This includes the use of innovative techniques to form the specific evaluative questions being asked and tested, to gather the right type of data and information on outcomes and intermediating variables, to explain findings and to disseminate them to the appropriate decision-makers. This paper will review this work. It will canvass a purposeful sample of experts from a variety of disciplines to gather the success stories, and where apparently well-planned approaches have failed to add the value expected of them. It will then draw lessons for future evaluations as a basis for guidance on the use of mixed methods.
SAO, AO, QBO, and Long-term trend of the peak OH airglow emission

Published: May 2023

Abstract. Based on the volume emission rate of the OH airglow observed by TIMED/SABER, we fitted the peak emission rate and the peak height of the OH airglow and analyzed the seasonal and interannual variations of both. The results show similar latitudinal variations in the semiannual oscillation (SAO) and annual oscillation (AO) of peak emission rate and peak height: the amplitude of SAO is greatest in equatorial regions and AO is greatest in mid-latitudes. For interannual variations, we find that OH airglow emission in equatorial regions is modulated by the quasi-biennial oscillation (QBO), while the QBO signal at other latitudes is much weaker than in equatorial regions and can be ignored. The QBO in OH airglow is consistent with the phase variation of the QBO in the tropical lower stratosphere (30 km), which is also consistent with the phase variation of the QBO in the migrating diurnal tide. As an important kinetic process affecting OH airglow emission, we suggest that the tides play an important role in the modulation of the OH airglow by the QBO. In addition, we have analyzed the relationship between peak OH airglow emission and solar activity. The results show a good correlation between peak emission rate and solar activity, with a correlation coefficient of 0.89, while peak height shows no significant solar cycle variation, with a correlation coefficient of −0.66. The modulation of peak emission rate by solar activity has significant latitudinal variation. The modulation effect is weakest in the equatorial region and greatest at mid-latitudes in both hemispheres.
Review article: Towards Improved Drought Prediction in the Mediterranean Region – Modelling Approaches and Future Directions
Authors: Zellou Bouchra , El Moçayd Nabil , Bergou EL Houcine
Published: May 2023

Abstract. There is a scientific consensus that the Mediterranean region (MEDR) is warming and as the temperature continues to rise, extreme events such as droughts and heat waves are becoming more frequent, severe, and widespread. Given the detrimental effects of droughts, it is crucial to accelerate the development of forecasting and early warning systems to minimize their negative impact. This paper examines the current state of knowledge in drought modeling and prediction using statistical, dynamical, and hybrid statistical-dynamical models, and suggests some research prospects to further improve drought prediction in this region. The review finds that while all methods have their strengths and shortcomings, hybrid statistical-dynamical methods can perform the most skillful prediction with a long lead time. However, the application of these methods is still challenging due to the lack of high-quality observational data and the limited computational resources. Finally, the paper concludes by discussing the importance of using a combination of sophisticated methods such as data assimilation techniques, machine learning models, and copula models and integrating data from different sources (e.g., remote sensing data, in-situ measurements, and reanalysis) to improve the accuracy and efficiency of drought forecasting.

MOVIMENTO NEGRO UNIVERSITÁRIO PELO OLHAR DOS LETRAMENTOS ACADÊMICOS: PRÁTICAS TRANSFORMADORAS E PERTENCIMENTO ACADÊMICO
Authors: Santos Juliana Silva
Published: May 2023

Este artigo, desenvolvido a partir dos estudos dos letramentos como prática social e das relações étnico-raciais, objetiva lançar olhares sobre o movimento negro apontando elementos que o caracterizam como agente de letramento acadêmico. Para uma melhor compreensão desse aspecto, foi feita uma pesquisa de campo com um grupo de estudantes negros de uma universidade pública brasileira a partir de uma abordagem etnográfica como enfoque teórico-metodológico. Como resultado, foi possível depreender que a agência do movimento negro acadêmico apresenta um caráter afirmativo e que promove uma transformação gradativa dos letramentos acadêmicos, tanto por meio da busca por pertencimento efetivo da população negra no espaço universitário quanto pela inserção de sua história, saberes e trajetórias.
