Addressing the dollar crisis by investigating underlying causes, effects, and strategic solutions in emerging economies

Foreign exchange reserves (FER), especially dollar assets, are vital for a developing country to maintain economic stability, foster growth, and protect against unexpected amendments. In recent years, particularly since the onset of COVID-19, several emerging countries have experienced significant economic hardship due to a crisis in foreign reserves. This has led to inflation and disruptions in supply chains, healthcare, and various service facilities. Despite the gravity of this issue, previous studies have not investigated the causes and consequences of such sudden crises. This study aims to fill this gap by investigating the causes and consequences of sudden FER crises in a developing country, specifically Bangladesh, through a systematic review. The study also explores innovative process-oriented policies to mitigate the immediate FER crisis. The systematic literature review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. It included 90 articles published between 2020 and 2023. The results discovered that the FER crisis in Bangladesh has been triggered by both external factors (such as the COVID-19 pandemic, the Russia-Ukraine conflict, trade imbalances, and remittances) and internal factors (including large infrastructure projects, complexities in the banking sector, local project subsidies, a managed floating exchange rate, and an over-reliance on the ready-made garments sector). These factors escorted deflation of the national currency, causing further inflation, declining domestic purchasing capacity, and raising concerns about food security. Additionally, price hikes and unauthorized storage of daily necessities made accessing daily essentials challenging for locals. The government has implemented three policy interventions, including managing consumer demand, safeguarding the supply of goods, and regulating continuous market monitoring to overcome the challenges. This study proposes eight innovative process-oriented policy recommendations for mitigating the immediate foreign exchange crisis and promoting sustainable economic development. Overall, this study offers valuable contributions in developing sustainable global economic policies. It fosters improved recovery and reuse of materials and energy while advancing long-term growth in developing nations.

Reanalyzing Variable Agreement with tu Using an Online Megacorpus of Brazilian Portuguese

We reanalyze the phenomenon of verbal (non)agreement with the 2SG tu in a megacorpus of Brazilian Portuguese compiled from the web. Unlike previous research, which has analyzed sociolinguistic interview data and regional differences, we examine these data with a focus on the internal linguistic factors that constrain the variability. Our analysis of 4860 tokens of tu + verb reveals that non-agreement with the 3SG verb form is by far the most common pattern, 2SG agreement being relatively infrequent. Individual verb lexemes show highly distinct rates of (non)agreement. In addition, the specific tense/aspect/mood forms and main/auxiliary status are likewise significant factors affecting the variation. We conclude that future studies of this phenomenon should not ignore these internal linguistic factors. We situate our study within a group of other recent studies in Romance linguistics, which have found that individual verbal and constructional patterns can have diverse effects on morphosyntactic variation.

Investigated the role of community based approaches for biodiversity conservation and socio-economic development in Bale Mountains National Park, Southeast Ethiopia

Community based conservation approaches are the holistic way to ensure appropriate biodiversity conservation and livelihood improvement in many protected areas across the world. However involvement of local community in conservation activities and benefit sharing in many protected areas are not well implemented. The purpose of this study is to investigate the role of community based conservation approaches for biodiversity conservation and socio-economic development. To address the stated objectives, required data were gathered from both primary and secondary sources. The result of the study revealed that parks provide various benefits for the local communities which are found in and adjacent to the park. Regarding perceived benefits from park, there was significant difference among community based association and non-community based association at (X2 = 92.071, df = 1, P < 0.05) while no significant difference was observed across kebeles. In spite of variation in perception among local community on park conservation, it was revealed that the communities contribute towards conservation of the park by controlling outbreak of fire and informing wildlife attack. Regarding strengths and weakness of community based conservation approaches as the finding indicated that internal factors out weight the external factors which imply that implementing the approaches is crucial for successful conservation of the park.

Green supply chain management and firm sustainable performance: unlocking the role of transactional and transformational leadership in firm sustainable operations

AbstractCompanies are adopting innovative and environmentally friendly methods and technologies to mitigate the adverse effects of their products and services on the natural environment. Various internal and external factors influence a company’s ability to comply with such sustainability standards. This study specifically examines the connection between a company’s sustainable supply chain operations and a crucial internal factor, namely leadership. It focuses on comparing and contrasting the impacts of transformational and transactional leadership on green supply chain management (GSCM) and the overall sustainable performance of the company. Using a quantitative approach, the author conducted surveys among employees and managers and utilized structural equation modeling to analyze the model. The findings indicate that transformational leadership significantly impacts GSCM practices and sustainable organizational performance (OSP). However, the association between transactional leadership and GSCM is relatively weak. Additionally, it is observed that GSCM positively contributes to OSP. The results emphasize the importance of upper-level management involvement in green initiatives, particularly GSCM, to enhance the company’s environmental performance and ensure its long-term sustainability.

The Coupling Mechanism between Railway Alignment Design and Resource Environment in the Southwestern Mountainous Areas of China

Faced with the characteristics of multifactor coupling and interweaving along the railway lines in the southwestern mountainous areas of China, researching the coupling mechanism and optimizing the collaborative development path between alignment designs and the resource environment is conducive to promoting the green and sustainable development of railways in these southwestern mountainous areas. In this study, first, regarding the environmental characteristics of engineering along the railway lines in the southwestern mountainous area, the key elements of the interaction and coercion between the alignment design (internal system) and the resource environment (external system) are identified, and the interactive impact mechanism of the “alignment design–resource environment” complex is revealed. Accordingly, a nonlinear coupling mechanism between the alignment design system and the resource environment system is established using the deviation coefficient coupling degree model. Second, from a methodological perspective, following a technical path of “analyzing the coercive effects of internal and external factors–identifying coupling relationships–discovering coupling laws–screening driving factors–proposing optimization plans–achieving collaborative development goals”, we propose an overall optimization plan to solve the problem. Finally, the Chengdu Changdu section of the X railway, which is located in a southwestern mountainous area, is taken as an example for this study. The results indicate that if the state of the external system of the KL scheme is continuously improved through the regulation of the u22 (crossing the ecological protection red line length), u23 (biodiversity impact), and u24 (ecosystem impact) indicators and that the internal structure of the line design is improved by optimizing the l12 (total length of bridges and tunnels) and l13 (number of stations) indicators, effectively driving the improvement in the u31 (land resource occupation) and u43 (land development intensity) indicators, the alignment design and resource environment will exhibit a mutually reinforcing coupling evolution trend and ultimately achieve an “alignment design–resource environment” composite system with higher quality coupling.

Spatial Heterogeneity and Driving Mechanisms of Cultivated Land Intensive Utilization in the Beibu Gulf Urban Agglomeration, China

Cultivated land intensive utilization (CLIU) exhibits spatial heterogeneity that is influenced by both natural and anthropogenic factors, with land dissected into different scale systems; however, CLIU has not yet been systematically explored. This study takes the Beibu Gulf urban agglomeration, a national-level model area for integrated land and sea development in China, as an example to investigate the spatial heterogeneity of CLIU and explore its driving factors through multiple econometrical and geographical methods, including identifying its underlying mechanisms. The results indicate that (1) the CLIU index is 0.334, its Gini coefficient is 0.183, and its comprehensive level has a low intensity and obvious spatial nonequilibrium characteristics. Hypervariable density (50.33%) and the intraprovincial gap (45.6%) are the main sources. (2) Among the independent effects of single factors, the multiple cropping index (0.57), labor force index (0.489), and intensification of construction land (0.375) exert the most influence on CLIU spatial variation. The interaction effects of two factors primarily manifested as nonlinear enhancements, with the interaction between the labor force index and multiple cropping index being particularly noteworthy (0.859). (3) The geographically weighted regression coefficients reveal that temperature (0.332), multiple cropping index (0.211), and labor force index (0.209) have relatively large and positive impacts on CLIU, while slope (−0.1), precipitation (−0.087), and population urbanization (−0.039) have relatively small and negative impacts; all factors exhibit spatial nonstationarity. The spatial heterogeneity of CLIU in the Beibu Gulf urban agglomeration is characterized by patterns’ nonequilibrium and factors’ nonstationarity. The driving mode of multiple factors on CLIU is manifested as follows: natural factors of cropland utilization provide basic guarantees, internal factors of CLIU provide positive enhancement, and external factors of land intensive utilization provide auxiliary promotion.

The Dynamics of Reports on the Belt and Road Initiative (BRI) in Cambodian Mainstream Media Before and After the COVID-19

The outbreak of the pandemic in early 2020 greatly slowed down the economic and trade exchanges as well as the cultural exchanges among countries. The Chinese government and media are facing challenges communicating internationally the “Belt and Road Initiative” (BRI). This paper selects the reports of mainstream media in Cambodia related to the “Belt and Road” Initiative before and after the epidemic, and comprehensively analyzes the research samples with the help of content analysis methods. By studying the law of “other shaping” of the image of the BRI reported by the Agence Kampuchea Presse (AKP) and the Phnom Penh Post, the two major mainstream media representing Cambodia’s official and private perspectives, respectively, it is helpful to analyze internal laws and explore the logic behind the discourse of the two Cambodia’s mainstream media; by excavating the attitude and value orientation hidden behind the Cambodian media towards the BRI, the paper comes up with the objective conclusion that the national interests and economic benefits brought by “the Belt and Road” projects are the key internal factors influencing the position of Cambodia’s mainstream media. The paper also notices that the spillover effect of China-US competition has an important impact on the Cambodian mainstream media’s coverage of the “Belt and Road” Initiative, and it also has significance for China to look at external communications and seek a breakthrough in vision by studying the international communication of the United States to Southeast Asia in history and learning from its successful experiences.

Deciphering the M-cell niche: insights from mouse models on how microfold cells “know” where they are needed

Known for their distinct antigen-sampling abilities, microfold cells, or M cells, have been well characterized in the gut and other mucosa including the lungs and nasal-associated lymphoid tissue (NALT). More recently, however, they have been identified in tissues where they were not initially suspected to reside, which raises the following question: what external and internal factors dictate differentiation toward this specific role? In this discussion, we will focus on murine studies to determine how these cells are identified (e.g., markers and function) and ask the broader question of factors triggering M-cell localization and patterning. Then, through the consideration of unconventional M cells, which include villous M cells, Type II taste cells, and medullary thymic epithelial M cells (microfold mTECs), we will establish the M cell as not just a player in mucosal immunity but as a versatile niche cell that adapts to its home tissue. To this end, we will consider the lymphoid structure relationship and apical stimuli to better discuss how the differing cellular programming and the physical environment within each tissue yield these cells and their unique organization. Thus, by exploring this constellation of M cells, we hope to better understand the multifaceted nature of this cell in its different anatomical locales.

Opting out of cardiac rehabilitation in local community healthcare services: Patients'perspectives and reflections.

Despite cardiac rehabilitation and medical treatment being integrated parts of the pathway of patients with cardiovascular disease, as well as the well-establish positive effect, cardiac rehabilitation remains underutilised. In recent years, cardiac rehabilitation has increasingly been moved from the hospitals to the community healthcare services. This transition may be challenging for patients with cardiovascular disease. To investigate reflections and perspectives of patients opting out of cardiac rehabilitation in community healthcare services to improve participation and adherence to cardiac rehabilitation in the future. A total of eight patients opting out of cardiac rehabilitation participated in individual interviews. Opting out of cardiac rehabilitation is defined as never enroled or did not complete cardiac rehabilitation. The Interpretive Description methodology was used in the analysis where two themes and six subthemes were identified: (1) 'Structural and organisational factors' with three subthemes; Being a patient in the healthcare system, Enroling into CR when it is meaningful, and Getting back to work is vital, and (2) 'Patients'internal factors' with three subthemes; Feeling a desire to regain control, Seeing yourself as recovered, and Being aware of own needs. The analysis indicates that patients'decision to opt out of CR was multidimensional and based on a combination of factors. Ensuring that the healthcare professionals in the community have sufficient information regarding the patient and a clear communication plan between the healthcare professionals and the patient may reduce the transition causing confusion and frustrations for patients. Incorporating a vocational element in CR and ensuring that employers understand the importance of CR may hamper returning to work as a challenge to CR. Ensuring timely CR referral and enrolment and a transition coordinator may reduce the challenge of patients not viewing CR as meaningful. However, further studies are needed to fully understand how CR could become meaningful for patients opting out of CR.

Numerical Simulation of Rainfall-Induced Erosion on Infiltration and Slope Stability

In slopes where a mixture of coarse and fine particles is present, the infiltration of rainfall can cause the migration of fine particles. This migration alters the hydraulic properties of the soil and has implications for slope stability. In this study, the slope under investigation is a tailings dam composed of loosely consolidated soil with a wide particle size distribution. Due to rainfall infiltration, fine particles tend to migrate within the voids of the coarse particle framework, leading to changes in hydraulic properties and inducing slope instability. The classical internal erosion constitutive model, known as the Cividini and Gioda erosion criterion, is commonly used to predict the behavior and effects of fine particle erosion in geotechnical engineering. However, certain parameters in this erosion criterion equation, such as long-term density, are challenging to obtain through experiments. To investigate the coupled evolution of seepage and erosion within landfill slopes under the influence of rainfall infiltration and to understand the mechanisms of slope instability, this research assumes the erosion of fine particle suspension and adopts the Worman and Olafsdottir erosion criterion to establish a coupled model of unsaturated seepage and internal erosion. The developed model simulates the coupled response of seepage and erosion in unsaturated landfill slopes under three different rainfall intensities. It is then combined with the infinite slope model to quantitatively analyze the impact of fine particle migration on soil permeability and slope stability. The numerical simulations provide the following findings: The Worman and Olafsdottir erosion criterion, unlike the Cividini and Gioda erosion criterion, only requires the determination of the soil’s gradation curve to estimate the erosion rate. Internal erosion primarily occurs within the leading edge of moisture penetration, accelerating the advancement of the wetting front and reducing slope stability. When the rainfall intensity is lower than the saturated permeability coefficient, the influence of internal erosion can be disregarded. However, under rainfall intensities equal to or greater than the saturated permeability coefficient, considering internal erosion results in a difference in the depth of the wetting front of up to 34.2 cm after 6 h in the R2 scenario. The safety factor without considering internal erosion is 1.12, whereas considering internal erosion yields safety factors between 1.08 and 1.09. In the R3 scenario, the difference in the depth of the wetting front reaches 53.8 cm after 6 h, with a safety factor of 1.12 without considering internal erosion and safety factors between 1.06 and 1.07 when considering internal erosion.

Exclamatory Responses: Foreign Students Difficulties in Learning Indonesian (A Case Study at JIKS Jakarta)

This study outlines the difficulties faced by foreign students, specifically Koreans, in learning Indonesian at the Jakarta International Korean School (JIKS). The difficulties are analyzed based on students' responses. Survey techniques with questionnaires and interviews were applied to explore their experiences in learning Indonesian. The objectives of this study are: 1) to identify the difficulties faced by foreign students in understanding and mastering Indonesian, and 2) to recommend several problem-solving solutions to enhance students' abilities in overcoming difficulties in learning Indonesian. The results of the study indicate that the learning difficulties in Indonesian for Korean students, particularly at JIKS, are predominantly due to external factors. The opportunities to practice Indonesian outside the classroom are very limited. Internal factors include the alignment of materials with learning needs, the students' varying abilities to absorb lessons, and the constant anxiety and lack of confidence in using Indonesian in front of others. The implications of this research will provide feedback for Indonesian language teachers who teach foreign students, particularly expatriate children from Korea.

Analysis of Employee Motivations and Causes in the Workplace

Employee motivation refers to an employees drive to complete work-related tasks. Employee motivation is an essential factor that every employer needs to secure to encourage the completion of tasks in a dignified and effective manner. Intrinsic and extrinsic factors influence employee motivation. The paper shows that factors internal to the employee influence their reaction to their external workplace factors that can determine how motivated they are to deliver the mandates. The paper considers the two aspects of the attribution theory, situational and dispositional, which shows that a persons internal factors determine how they react to the external environment and respond to motivation. This paper also considers how deviant behavior explains the origins of human behavior to show how internal factors can affect how employees respond to motivation. Internal and external organizational factors can also affect the effectiveness of the companys motivation strategy. The theories help establish that any motivational intervention should consider an employees factors to ensure its success and positively impact the company and its operations.

Feasibility of the BBNJ Agreement to regulate bioprospecting in the Southern Ocean

This paper investigates the potential regulatory frameworks applicable to marine bioprospecting in the Southern Ocean and considers the activity could potentially fall under the purview of both the Antarctic Treaty System and the Biodiversity Beyond National Jurisdiction Agreement. Through a comparative analysis, this paper discerns the overlap of application and divergence in rules between the two regulatory frameworks, particularly concerning the specific provisions for regulating marine bioprospecting. This includes dissecting differences in the rules regulating the procedures for access to marine genetic resources and the associated benefit-sharing mechanisms. By synthesizing the SWOT analysis and strategic analysis, this paper identifies the internal and external factors influencing the application of the BBNJ Agreement to bioprospecting regulation within the Southern Ocean. It concludes that, due to the priority application of ATS and the region`s unique geopolitical context, the BBNJ Agreement may encounter challenges in the direct implementation and governance of marine bioprospecting. The principle of not undermining should be observed to harmonize application with ATS. Meanwhile, the BBNJ Agreement may contribute to a self-revolution of the ATS in regulating marine bioprospecting, particularly in the aspect of mechanisms for equitable benefit-sharing.

Precise dating of large flank collapses by single-grain 40Ar/39Ar on pyroclastic deposits from the example of Flores Island (Azores)

Large-scale flank collapses are one of the main hazards associated with the evolution of volcanic islands. Precisely dating such events is critical to evaluate the frequency of destabilization episodes and further assess the triggering mechanism(s) associated with internal and/or external factors, such as volcano dynamics, regional tectonics, and global paleoclimatic changes. Here, we constrain the age of a pumice-rich pyroclastic deposit exposed on the eastern flank of Flores Island (Azores), which we interpret as a co-blast deposit generated by a major flank collapse that destroyed the whole western flank of the former volcanic edifice. Twelve single-grain 40Ar/39Ar analyses, performed on 250–500 µm anorthoclase feldspars (mean K/Ca close to 5) with our high-sensitivity multi-collector NGX mass spectrometer, provide a robust weighted mean age of 1.32 ± 0.01 Ma for this eruption. This new age is consistent with previous K/Ar data bracketing the flank collapse between 1.30 ± 0.04 and 1.18 ± 0.09 Ma, and indicates that this event occurred at the end of the main construction phase of the volcano. The explosion produced pumice-rich layers preceded by a lahar as attested by a polygenetic mudflow deposit underlying the dated deposit. From the geochemistry of lavas erupted just before and after the collapse, we speculate upon the possible role of magmatic processes on flank destabilization. We propose a first hypothesis where differentiation in a shallow magma reservoir could have favored edifice inflation, ground shaking, and flank failure, triggering a decompression-induced violent eruption. Overall, our study shows that high-sensitivity mass spectrometers have now reached analytical performances allowing to measure precisely and accurately ages on relatively small and moderately K-rich single feldspars, which is of the utmost importance for dating heterogeneous blasts and tephra deposits that may have been induced by large-scale flank collapses during the late Quaternary.
