The teacher's competence in integrated teaching at secondary schools: A case study in Vietnam

Integration of teaching is described as the systematic arrangement of knowledge in teaching to combine or unify matters of subject isolated in the academic curriculum. The purpose of this study is to investigate Vietnamese teachers, principals, and vice-principals in secondary schools' awareness and the implementation of integrated teaching in Natural Science subjects in secondary schools, Hoc Mon District, Ho Chi Minh City, Vietnam. Participants completed survey questionnaires about the awareness about objectives for fostering quality integrated teaching, the objectives’ importance in integrated teaching, and the implementation of integrated teaching of Natural Science subjects. The results revealed that the integrated teaching in integrated teaching of Natural Science subjects was highly trained and well-implemented by secondary school teachers. The educational curriculum assists students in discovering, investigating comprehensive solutions, and examining various aspects of problems.
How Crowdfunders Are Influenced by Entrepreneurial Passion: A Dual Information-Processing Perspective

We incorporate entrepreneurial passion into a dual theory of information-processing, theorizing that passion can be used as information in analytical thinking, and as a heuristic in intuitive thinking. We find that passion is generally associated with an increase in crowdfunding success rates (+1%). Its effect becomes more powerful (+16% increase in success) when exhibited in conditions of coherence/fluency, that is, with high levels of preparedness, while it disappears in conditions of incoherence/disfluency and when the judgment is important. This conceptual framework reconciles contradictory findings of previous studies, suggesting that affective cues have the power to influence decisions in contexts characterized by large numbers of non-professional investors.
Key driving factors of cost overrun in highway infrastructure projects in Nigeria: a context-based perspective

Purpose Extensive research towards identifying the attributable cost overrun factors globally has been conducted predominantly from a survey-oriented perspective, which disregard the contextual basis on which these triggers manifest. This study aims to explore the driving factors of cost overrun in highway projects, specific to the Nigerian context. Design/methodology/approach The research used a context-based approach to seek project stakeholders’ perspectives on the key drivers of cost overrun in highway projects in Nigerian. Semi-structured interviews were conducted with client, contractor and consultant organisations involved in the provision of highway infrastructure projects in Nigeria. The collected data was analysed using a developed coding framework grounded on a case study approach, principles of inductive thematic analysis and saliency analysis to identify the key drivers. Findings Findings from the analysis identified triggers from macroeconomic, societal, leadership and project management perspectives with synergistic relationships with each other based on prevalence and significance. Among the key triggers is a delay in work progress, political instability, adverse weather, social issues, delay in progress payment to contractors and modification of project scope. In conclusion, the triggers of cost overrun in highway projects are contextually driven by the complex nature of the project management, societal, macroeconomic and leadership triggers specific to the Nigerian context. Research limitations/implications The research was limited to only highway infrastructure projects in Nigeria. Furthermore, the findings are based on a small sample size, and thus, caution must be taken before applying the outcome of this study in a generalised way to other contexts. Practical implications Practically, the stakeholders i.e. client, contractors and consultants should acknowledge the contextual circumstances in which each of the triggers takes place, which will aid in developing pragmatic measures and make the right decisions towards addressing these triggers during any highway construction project in Nigeria and enhance the chances of project success. Originality/value The context-based approach applied in this study is expected to provide a new insight in understanding the triggers of cost overruns, especially in highway projects in Nigeria and indeed other developing countries with similar governance characteristics
The wicked city: Genealogies of interdisciplinary hubris in urban thought

Across multiple academic disciplines and fields of policy, cities are now ascribed wide-ranging task responsibility for addressing a wide range of global issues. This paper elaborates a genealogical mode of analysis for understanding the ascription of causal and practical responsibility to urban processes. This analysis is developed through a case study of the revival of interest in the concept of wicked problems. The paper pinpoints aspects of the original account of wicked problems that are crucial to appreciating the significance now played by this concept in discourses of metrophilia. The focus is on the specific sense of ‘wickedness’ outlined in this original account. The career of the wicked problems idea is reconstructed, with an emphasis on different views of expertise and how these are related to the changing status of the city in recent accounts of wicked problems. The paper identifies differences and similarities between the two A cc ep te d A rt ic le
Recycling of Marine Carbonate Induced Calcium Isotope Heterogeneity of Arc Magmas in Subduction Zones

Calcium (Ca) is an essential element constituting sedimentary carbonate in subducting sediments. Ca isotopic characteristics of subduction-related rocks could provide insight into the behavior and budget of carbonate and carbon cycles in subduction zones, due to the distinctive δ44/40Ca ranges of sedimentary carbonate with respect to the mantle. Here, we studied the Ca isotopic compositions of arc magmas from the Northern Luzon arc (NLA), which are evolved from a depleted mantle metasomatized by slab-derived fluids and sediment melts. The δ44/40Ca values range from 0.76 ± 0.04‰ to 1.01 ± 0.03‰ and cover the typical ranges for bulk silica earth (BSE, ~ 0.94‰) and fresh mid-ocean ridge basalt (MORB, ~ 0.83‰). The Ca isotopes of NLA volcanics are not dominantly determined by the effects of mantle partial melting or fractional crystallization, nor significantly modified by secondary alteration. Instead, the δ44/40Ca values of NLA volcanics are controlled by the subduction-related metasomatism. The metasomatism by slab-derived fluids (mainly expelled from altered oceanic crust, AOC) dramatically elevated the contents of fluid-mobile elements (e.g., Ba and Pb) with respect to fluid-immobile elements (e.g., Ce). This process, however, rarely modified the Ca isotopes, possibly ascribed to the δ44/40Ca similarity between AOC and the depleted mantle. The δ44/40Ca values significantly correlated with subduction indicators (e.g., Sr-Nd isotopes, Ba/Nb, Ce/Pb, and Nb/La), demonstrating the Ca isotopes of NLA volcanics are mainly controlled by the metasomatism of sediment melts subducting from the South China Sea (SCS). Based on the thermal structures and chemical compositions of sediments subducting into global trenches, we propose that carbonate Ca isotopic signals can only be observed in the arcs with high sedimentary Ca fluxes and temperature-pressure conditions well beyond the solidus of H2O-saturated sediment melting, e.g., NLA, Nicaragua, Guatemala, Colombia, Peru, South Chile, North Vanuatu, New Zealand, and Kermadec. The absence of such signals in other arcs suggests either limited sedimentary fluxes or much of the subducting sedimentary carbonate has been survived during plate subduction to enter the deep mantle.
Examining the Relationship between the Fear of COVID-19, Resilience and Religion

The relationship of fear of COVID-19, resilience, and religiosity in the COVID-19 Global Pandemic, which affects life in many areas of psychological, social, economic, cultural, religious, has been examined in this study. In this study, 337 people, including 219 women (65%) and 118 men (35%), participated. The present research was a descriptively based quantitative study based on the relational survey model. COVID-19 Fear Scale, Brief Resilience Scale and Religiosity Scale were used to collect data. In addition, a Personal Information Form was used to obtain information and opinions about COVID-19 and determine demographic characteristics. The t-test, correlation and regression analysis were used in statistical processes. The findings obtained in this research showed that women have more fear of COVID-19 than men, and men have higher resilience and religiosity scores than women. In addition, it was observed that there was a significant and negative relationship between the fear of COVID-19 and resilience, religiosity and age, a significant and positive relationship between resilience and religiosity and age, and a significant and positive relationship between religiosity and age. Finally, it was found that resilience, religiosity and age together were predictors of COVID-19 fear. However, when looking at the t-test results of the significance of the regression coefficients, it was seen that only resilience was a significant predictor of COVID-19 fear. The findings obtained are discussed in light of the literature.
Conceptualisation of Psychological Contract: Definitions, Typologies and Measurement

Background: Psychological contracts, and particularly the honouring of these contracts – are central to employee behaviour and organisational success. The interest of academics and practitioners in this construct is therefore understandable. However, due to the immense amount of information on the topic, a comprehensive review of the literature is necessary. Aim: The aim of this article is to present a critical review on the conceptualisation of the psychological contract, distilling and operationalising the concept, to ensure that debate and future research are linked to a dominant body of knowledge. Setting: Present literature on psychological contracts is fragmented as no conceptual standardisation exists. Method: A comprehensive literature review was conducted to obtain a large quantum of conceptualisations of the construct and evaluate these for breadth of adoption, consensus, and operationalisation. Results: After reviewing reputable sources published between 1960 and 2020, a standard definition proposed, the most recognised typologies specified, and sound measures identified. It was found that Rousseau’s (1995) definition and typologies (transactional and relational contracts) are still widely used, and that the measuring scale for transactional and relational contracts by Millward and Hopkins (1998) demonstrates good psychometric properties and broadly utilised. Conclusion: Since its inception, several amended definitions, typologies, and measurement of the psychological contract have been presented. Nonetheless, the original conceptualisations still seem to prevail. Managerial implications: Researchers and practitioners are now aware of the most widely adopted definitions, typologies and measuring instruments relating to psychological contract and these should guide them in future discussions and research in the field.
Morphological and optical study of thin films of CuAlS2 deposited by metal organic chemical vapour deposition technique

Single solid source precursor of Copper–Aluminium dithiocarbamate was prepared and characterized by infrared spectroscopy. Thin films of copper aluminium sulphide were deposited on the substrate (soda lime glass) using metal organic chemical vapour deposition (MOCVD) technique within temperature ranges of 420 and 450 °C through the pyrolysis of the prepared precursor. Morphological and optical characterizations were then carried out. Morphological study carried out using scanning electron microscopy (SEM) showed that the deposited films are dense and polycrystalline in nature, uniform with the particle size distribution of the grains decreasing with increase in temperature. A direct optical energy gap of 3.28 and 2.88 eV were obtained for films deposited at 420 and 450 °C respectively. Other optical constants were found to increase as temperature increased.
Impact of the Covid-19 Pandemic on the Financial Performance of Sharia Commercial Banks: an Empirical Evidence from Indonesia

The Covid-19 pandemic has substantially changed the world. Social, economic, culture as well political landscapes have been forced to adapt to a new normal—a previously unfamiliar or atypical situation that has become standard, usual, or expected. This has, to some degree, obstructed economic activity throughout many sectors, with important aftermaths for businesses and households. Companies that have stopped operating will lose revenue, and, therefore, may not be able to repay the loan. Equally, households where family members lose their job or leave will experience a decrease in income which, in turn, will not be able to pay their loans or credit installments. This phenomenon will result not only in lost revenue but also to losses which has the potential to negatively affect bank profits and capital. This paper is aimed at analyzing the impact of the Covid-19 pandemic towards sharia commercial banks’ performance in Indonesia. The dependent sample t-test was performed to test the proposed hypotheses. It was revealed that the banks’ performances were not totally negatively affected by the Covid-19 pandemic. The growth rate of total assets the capital adequacy ratio (CAR), non-performing financing, and operating efficiency ratio were not negatively affected by this pandemic, however, returns on assets, financing to deposits ratio, and net operating margin were negatively affected by the pandemic.
Quantifying Tectonic and Glacial Controls on Topography in the Patagonian Andes (46.5°S) From Integrated Thermochronometry and Thermo‐Kinematic Modeling

The Patagonian Andes have been used to illustrate the dependency of major topographic changes in response to glacial erosion processes dominating over tectonic deformation and uplift. Here, we investigate tectonic and glacial contributors to the erosion history and evolution of topography in the Patagonian Andes at 46.5°S. We present 33 new apatite and zircon (U‐Th)/He (AHe and ZHe, respectively) and fission track (AFT and ZFT, respectively) ages integrated with 46 previously published bedrock thermochronometric ages in a 3D thermo‐kinematic model. Observed thermochronometer ages increase from the eastern flank of the topographic crest of the orogen toward the eastern retro‐foreland basin (from AFT 4–10 Ma, ZHe 4–12 Ma, ZFT 6–14 Ma to AFT 28–32 Ma, ZHe 68–117 Ma). Thermo‐kinematic modeling indicates that spatial gradients in thermochronometric ages can be explained by an up to 100‐km‐wide, parabolic‐shaped pattern in exhumation rates with a maximum rate of 0.5 mm/yr from 15 Ma until the onset of glaciation at ∼7 Ma. Furthermore, model results suggest that the youngest AHe ages require a localized acceleration in erosion from ∼0.5 mm/yr to ∼2.2 mm/yr starting between ∼5 and ∼3 Ma, coeval with intensified glaciation and subduction of the Chile Rise. Our results suggest that the long‐wavelength (∼100 km) topography and erosion patterns are likely controlled by rock uplift above mid‐crustal ramp(s) and subsequent transpression along the Liquiñe‐Ofqui Fault. Superposed on these tectonic processes, Late Cenozoic glaciation resulted in localized and accelerated erosion over wavelengths of <20 km.
Mosquito Bed Net Preferences and Efficacy in the Prevention of Gestational Malaria in Yaounde, Cameroon

Malaria prevention methods are diverse. Their availability sometimes does not guarantee effective usage and the use of each method in isolation may not provide the necessary results for the fight against malaria. Pregnant women are relatively more vulnerable and so it is recommended that they should be protected against malaria. Proper protection will require the use of long lasting insecticide treated mosquito bed nets as major malaria prevention method. This study was designed to find out malaria prevalence and factors influencing the use of mosquito bet nets among pregnant women of Biyem-Assi Health District. Information on the knowledge of malaria and use of malaria prevention methods, especially bed nets was collected from 302 pregnant women attending prenatal clinics in health institutions within the Biyem-Assi Health District of Yaounde VI subdivision using a pretested questionnaire. Thick smear was prepared for screening Plasmodium parasites. Analysis was done using EPI INFO version 16 (Chicago IL USA) and test of Chi 2. The study revealed that malaria prevalence was 48.5%. The shape of mosquito net had a significant (P = 0.05) effect on its use and a reduction on prevalence of malaria. The use of mosquito bed net was 47.7% while some of the women (52.3%) did not use it. Profession significantly influenced (P ˂ 0.04) the use of mosquito bed nets. Some of the women did not use mosquito bed nets for different reasons such as heat, forgetfulness, neglect, dislike, etc. The shape and color influenced the use, but this was not significant. Use of mosquito bed nets as major malaria prevention methods is not considered as priority by pregnant women. Sensitization campaigns by government and NGOs should reduce malaria prevalence during pregnancy and give a priority position to mosquito bed nets.
An analytical study of abnormal uterine bleeding in women of child bearing age group

Background: AUB (abnormal uterine bleeding) is defined as any variation from the normal menstrual cycle including alteration in its frequency, regularity of menses, duration of flow and amount of blood loss. In India, the reported prevalence of AUB is 17.9%. It can occur any time between menarche to menopause. A good clinician tries to recognize and identify the causative factors responsible for the disease, reverse the abnormality and induce or restore the cyclic predictable menses which should have normal volume and duration.Methods: 200 cases of AUB fitting the selection criteria were taken from OPD and gynecology ward between September 2020 to June 2021.Results: AUB was more common in the age group 41-45 years, that is, perimenopausal age group, more in multiparous women and women with previous surgeries on uterus and adnexa. Heavy menstrual bleeding was the most common complaint. Endometrial hyperplasia was the most common finding on ultrasound examination. Medical therapy was beneficial in some patients, rest had to undergo surgical intervention later.Conclusions: Transvaginal sonography is very accurate in assessing the endometrium as well as uterus and adnexa and diagnosing their abnormalities. Medical therapy is the first line of management in most cases. Dilatation and curettage should be used along with hysteroscopy for better results. LNG-IUS gives very good result in suitable cases. Hysterectomy is the final measure if everything else fails. Vaginal hysterectomy is preferred wherever possible.
The impact of social media marketing for Indonesian SMEs sustainability: Lesson from Covid-19 pandemic

Abstract The Covid-19 pandemic has imposed the government to provide a mass restriction policy, and businesses respond to this issue by adopting technology and social media marketing. This study aims at highlighting the determinant factors affecting technology adoption, social media marketing, and business sustainability. The study involved a quantitative approach with partial least squares structural equation modeling to obtain a deep understanding of this phenomenon. The research was incorporated with small and businesses in East Java Provincial in Indonesia employing an online questionnaire. The findings show that the adoption of internet/e-business technology can be explained by perceived usefulness, perceived ease of use, and cost. Furthermore, it has a link between internet/e-business technology, social media marketing, and SMEs’ sustainability. However, the cost variable failed in demonstrating the implementation of social media marketing by SMEs. This work strongly suggests that the adoption of internet/e-business technology and social media marketing successfully explains the mediating role between variables. Despite this work solely conducted in East Java, this research is the initial phase in a study associated with SMEs’ sustainability in the Covid-19 pandemic in Indonesia.
A Takagi-Sugeno Fuzzy Model for Greenhouse Climate

This paper investigates the identification and modeling of a greenhouse's climate using real climate data from a greenhouse installed in the LAPER laboratory in Tunisia. The objective of this paper is to propose a solution to the problem of nonlinear time-variant inputs and outputs of greenhouse internal climate. Combining fuzzy logic technique with Least Mean Squares (LMS), a robust greenhouse climate model for internal temperature prediction is proposed. The simulation results demonstrate the effectiveness of the identification approach and the power of the implemented Takagi-Sugeno Fuzzy model-based algorithm.
Impact Versus Frictional Earthquake Models for High‐Frequency Radiation in Complex Fault Zones

Earthquakes occur within complex fault zones containing numerous intersecting fault strands. This complexity poses a computational challenge for rupture models, which typically simplify fault structure to a small number of rough fault surfaces, with all other deformation assumed to be off‐fault viscoplastic deformation. In such models, high‐frequency ground motions originate solely from frictionally mediated, heterogeneous slip on a small number of potentially rough fault surfaces or from off‐fault viscoplastic deformation. Alternative explanations for high‐frequency ground motion generation that can account for a larger number of fault surfaces remain difficult to assess. Here, we evaluate the efficacy of a recently proposed stochastic impact model in which high‐frequency ground motion is caused by elastic impacts of structures within a complex fault zone. Impacts are envisioned to occur in response to fault motion in the presence of geometrical incompatibilities, which promotes transfer of slip onto different fault strands on timescales mediated by elasticity. We investigate the role of a complex fault zone for high‐frequency ground motion by comparing the underlying assumptions and resulting predictions of impact and rough fault frictional models. Relative to rough fault frictional models, impact models are characterized by deformation timescales and corner frequencies that are set by elasticity rather than viscoplasticity, relatively angular rather than smoothly varying fault roughness geometries, high‐frequency radiation patterns that are more isotropic, and higher P/S radiated energies. We outline ways to discriminate whether impact or rough fault frictional models are more likely to explain observations of high‐frequency ground motions.
