Labour market, social welfare, and migrant remittance: COVID-19 implications in the UK
Authors: Kaya Tilbe Fethiye 
Published: August 2023

AbstractImmediately after the COVID-19 pandemic was declared by the World Health Organization on 11 March 2020, most countries took measures to prevent international human mobility. While the economic consequences of the pandemic significantly reduced remittances sent by migrants through formal channels, restrictions on human mobility almost halted the cross-border movements of remittances through informal channels. Policy measures related to the labour market and social welfare practices have also played determining roles in remittance transfers. This paper aims to examine how the labour-market participation of migrants and pandemic-induced financial support affect remittances sent migrants to their home countries during the COVID-19 outbreak. The author used an inductive approach and analysed qualitative data from two groups of Turkish migrants with different status in the UK labour market. The findings demonstrate that during the COVID-19 pandemic measures to restrict human mobility, migrants’ income/job losses, and dependence on tightly regulated financial support can have devastating effects on remittances sent from the UK to Turkey through both formal and informal channels. This study contributes to remittance literature by evincing the vicious cycle of irregularity in the relationships among remittances, labour markets, and welfare regulations in host countries. In countries with a tight regulatory system, irregularity in the labour market brings about irregularities in money transfers. In possible future events where there is a high probability of an economic downturn and travel restrictions, such as pandemic, natural disasters, armed conflicts and so on, especially for migrants, it is important to set a minimum base wage which can be referred to as ‘Temporary Basic Income Support’. This policy proposal is important as measures that facilitate remittance transfers through formal channels, are one of the most important means of reducing global inequalities and disadvantages.

Published: August 2023

Abstract
In 1898, a young Dane, Anker Jensen (1878–1937), published a pioneering study in which he investigated the linguistic
situation in Aaby, then a village and parish located just west of Aarhus (the second-largest city of Denmark, in Jutland), and today an
integrated part of the city. Anker Jensen’s article can safely be considered the first sociolinguistic study in a Danish context, and it may
in fact be the world’s first quantitative sociolinguistic study altogether. Jensen’s research was ahead of its time, and written in Danish,
and for these reasons it has gone largely unnoticed internationally. In this article, we present an introduction to Anker Jensen’s Aaby
study, providing background information and additional context for modern readers, as well as offering an overview of the author’s collected
works, both published and unpublished. We also briefly discuss our translation into English of the original 1898 article. The translation is
likewise published in this issue of Historiographia Linguistica.

Abstract
In this paper, we presented the 23.3 yr of pulsar timing results of PSR J1456−6413 based on the observations of Parkes 64 m radio telescope. We detected two new glitches at MJD 57093(3) and 59060(12) and confirmed its first glitch at MJD 54554(10). The relative sizes (Δν/ν) of these two new glitches are 0.9 × 10−9 and 1.16 × 10−9, respectively. Using the “Cholesky” timing analysis method, we have determined its position, proper motion, and two-dimensional transverse velocities from the data segments before and after the second glitch, respectively. Furthermore, we detected exponential recovery behavior after the first glitch, with a recovery timescale of approximately 200 days and a corresponding exponential recovery factor Q of approximately 0.15(2), while no exponential recovery was detected for the other two glitches. More interestingly, we found that the leading component of the integral pulse profile after the second glitch became stronger, while the main component became weaker. Our results will expand the sample of pulsars with magnetosphere fluctuation triggered by the glitch event.
A Study of Elemental Abundance Pattern of the r-II Star HD 222925

Published: August 2023

Abstract
HD 222925 is a rare r-process enhanced star in the Milky Way because of its metal abundance ([Fe/H] =−1.46 ± 0.10) and Eu abundance ([Eu/Fe] = 1.32 ± 0.08). Based on the very complete set of elemental abundances of HD 222925, we use the abundance decomposition method to fit the observed abundances of 58 elements in the sample star, which is also the largest number of elemental abundances fitted at the same time for a fixed star. We analyze the astrophysical origins of elements in HD 222925 by its abundance ratios and component ratios. It is found that the light elements and the iron group elements in HD 222925 mainly originate from the primary process of the Type II supernovae (SNe II) with the progenitor mass M > 10 M
⊙ and have no contribution from SNe Ia and the first generation of very massive stars. The contribution of the weak r-process to Ga, Ge, and As is superior to that of the other processes, and its contribution decreases linearly with increasing atomic number. The main r-process that is likely derived from a neutron star merger plays a key role in the formation of neutron-capture elements (Z ≥ 38) in HD 222925.

Abstract
Some decommissioned solar photovoltaic (PV) modules from solar power plants are still well-performed and worth reusing. Test procedure and conditions to separate between functional and expired modules is thus key points. This study has proposed a 3-step process; 1) visual inspection, 2) insulation test and 3) outdoor current-voltage (I-V) curve measurement, to preliminary screen and divide modules into six groups: A+, A, B, C, D and F. The review criterion covers quality, safety and reliability aspects. All processes have been carried on-site and test results have been recorded in a software tool called ‟Solar Sure”. 258 retired PV modules from six solar farms in Thailand has been surveyed. It was found that some multi c-Si modules showed very low insulation resistance. 74% of the total amount of modules in this study still have the maximum power output of above 70% of their initial value, suggesting a potential for second use. The observed results of this preliminary survey are informative for a further study on field-aged PV reliability in the tropics and also useful for a preparation of a guideline for promoting reuse of decommissioned functional PV modules in Thailand.

Abstract
Energy storage system research including battery and supercapacitor devices has been studied to increase efficiency, lower their cost and improve environmental friendliness. Supercapacitor (SC) device offers high transient response and power density which suitable for many applications. The electrodes in supercapacitor device usually produced from highly porous carbon materials. In this study, the modified mesoporous carbon was produced from Palm empty fruit bunch (EFB) biomass. The production of mesoporous carbon was done using a low-temperature hydrothermal carbonization process. The mesoporous carbon from EFB biomass has shown good properties in terms of high surface area and porosity. To improve the electrical conductivity of the carbon the modification by nitrogen doping with ammonium chloride and urea was studied. The effect of different nitrogen sources on surface area and pore properties were reported. The modified mesopore carbon was tested in a symmetrical swagelok supercapacitor cell to evaluate the specific capacitance and efficiency using galvanostatic charge-discharge method. The modified mesoporous carbon with urea doped exhibits the highest specific capacitance of 121 F g-1 at current loading of 0.1 A g-1 in an aqueous 1M H2SO4 electrolyte. The modified mesoporous carbon with urea doped has lower internal resistance due to nitrogen from urea enhance the electronic conductivity of the electrodes and thus increase the supercapacitor performance.
Potential Integration of Waste to Energy (WtE) and Carbon Mineralization Technology in Indonesia

Published: August 2023

Abstract
Several issues such as environment, finance, and policies in the development of Waste to Energy (WtE) in Indonesia require strategic and appropriate handling. This study offers a promising solution by integrating WtE incineration process with carbon mineralization as one of Carbon Capture, Utilization, and Storage (CCUS): adding CO2 capture technology to the existing system and CO2 will be reacted with fly ash residue producing insoluble carbonates to stabilize the heavy metals contained. Moreover, with a combustion capacity of 1000 tons of waste/day scenario, it is equivalent to a reduction of carbon emissions of up to 25 tCO2 per day. A feasibility study in Estonia revealed that if WtE is integrated with carbon mineralization, the resulting Net Present Value (NPV) is up to 9,209,662 EUR. This can be an opportunity for Indonesia to solve the financial issues as the existing WtE only generates 133,500 EUR of NPV. Additionally, the existing policy states that the construction of a WtE plant must be accompanied by a residue treatment plant facility. So that in addition to increasing profits and environmental benefits, this integration also can help simplify the complexity of WtE development requirements because residue treatment becomes easier.
Application of Demand-Side Management (DSM) for evaluation and optimization of Electric Vehicle’s charging cycles
Authors: Vu Giang N H , Hoang Nhat , Nguyen Tuyen D 
Published: August 2023

Abstract
Electric vehicles (EVs) have been known as potential transportation alternatives for internal combustion engines thanks to lower carbon emissions and high energy efficiency. The combination of EVs with other renewable energy sources (RES) is a viable solution for eliminating the emission on the road and during the electricity generation process, reducing the reliance of EVs energy demand on the non-renewables. However, the higher penetration of EVs and unpredictable charging dynamics could burden the power system tremendously. This study proposes a demand-side management (DSM) strategy for an EVs-integrated residential grid with the assistance of grid-tied rooftop photovoltaic (PV) systems. The main objectives are to minimize the peak and fluctuation load while ensuring the EVs’ effective charging and vehicle-to-grid (V2G) scheme based on time-of-use (TOU) tariff and real-time pricing (RTP). The EVs’ traveling distances, driving periods, initial state-of-charge (SOCs), and plugging states are considered. One-day simulation in different scenarios was carried out to evaluate the strategies. The results indicate that the proposed model can reduce load demand, flatten the load curve, and reduce electricity costs, maintaining the system’s stability. The approach can be an indicator for load aggregators and utilities to manage PEVs as DSM tools in the system.
Water Tenure Security for Palm Oil, Hydropower, and Geothermal
Authors: AlAfghani Mohamad Mova , Susetyo Budi 
Published: August 2023

Abstract
Oil palm plantation, hydropower and geothermal depend on water to sustain their operations. This paper will analyze two factors affecting its water tenure security: how water is allocated in the legal framework and the relative strength of a particular tenure against other tenures. The case study areas are the Kahayan Catchment (Central Kalimantan) and the Citarum Catchment (West Java). This paper applies FAO’s analytical framework: elaborate tenure typology, map water uses and weigh the security of the particular tenure with some modification. We find that the water tenure security for oil palm is weak since it sits at the bottom rung of the allocation framework. We posited that environmental water use, especially for the prevention of forest fires – as well as water, uses for daily basic needs would be prioritized over commercial water use for smallholder oil palm farmers or corporate oil palm. Furthermore, customary water tenure, although weak in the legal sense (de jure), can be strong in terms of practice (de facto); this could diminish oil palm water tenure security should there be an overlap or intersections among them. Water tenure security for hydropower is “weak to medium” – but this depends on whether they are related to investment schemes that could strengthen their tenure legally. In the legal framework, the allocation for hydropower is prioritized below daily basic needs, drinking water utilities, and smallholder crops. Following a legal analysis, we find that the strength of water tenure for geothermal in conservation area is weak.
The Relationship between Sustainability Performance and Financial Performance with External Assurance as the Moderating Variable in Indonesian Listed Companies
Authors: Dewi A , Widyawati L 
Published: August 2023

Abstract
Sustainability reporting has been mandated in several ASEAN countries, and the trend toward more extensive reporting is expected to continue due to regulatory and market pressures. Sustainability reporting would be expected to be the subject of external assurance to bring competitive advantage through verifiable quality of sustainability performance information. This study aims to examine the relationship between sustainability performance disclosure and financial performance as well as how external assurance moderates the relationship. This study contributes to the literature by highlighting the importance of external assurance as a quality enhancement mechanism for sustainability performance information. This study employs quantitative research, specifically a regression analysis of empirical cross-section data using samples from 63 listed companies in Indonesia that published sustainability reports in 2020. The sustainability performance disclosure is measured based on the disclosure required by Circular Letter SEOJK/16/2021. Financial performance is measured by price to book value, and the provision of external assurance is used as the moderating variable. The results indicate that sustainability performance disclosure and financial performance do not show a significant relationship unless the sustainability report is externally assured. The assurance has been found to positively moderate the previously insignificant relationship; hence, external assurance was considered a relevant, strong, and credible signal for investors.

Published: August 2023

Abstract
Comfort of the building is one of the important factors that is hard to achieve for architects and engineers as it depends on both physic and psychological parameter. This paper discusses these two aspects on the thermal performance of residential building in context of hothumid climate. Three different types of residential buildings including townhouse, detached house and apartment building in Phnom Penh, Cambodia were chosen as the case studies. The analysis of thermal performance of each house is based on (a) the measurement of physical parameters (air temperature, relative humidity, air velocity), (b) occupants survey to compare with data from the measurement and (c) interview with the occupants to know about their satisfaction and sensation to the physical parameters. Impact of different designs of houses on thermal performance and the importance of influential physical parameters for tropical climate is analysed. Comparison of results to the Fanger’s model also indicate the importance of air velocity in thermal comfort for tropical region. The survey shows that in natural ventilation, women in their 20s to 30s feel comfortable with the temperature of 29 to 30°C and humidity of 73 to 75%.

Published: August 2023

Abstract
The purpose of this study is to evaluate and compare the efficacy of an anaerobic baffled reactor (ABR) and an anaerobic filter (AF) in treating medium-strength wastewater under natural sludge growth conditions and different hydraulic retention times (HRT) of 12h and 24h. The ABR reactor has five compartments with a total capacity of 71 L, whereas the AF reactor with 70% sponge bio-media has five compartments with a total volume of 51 L. Both reactors required 13 weeks to achieve steady-state without adding sludge seeds during the startup phase. During that period, total suspended solid (TSS) removal was 80-90% in the AF and only 60-70% in the ABR. Furthermore, the average COD removal in the AF was determined to be 50-60% and 70-80% under HRT of 12h and 24h, respectively, but the ABR in these conditions could only accomplish 40-50%. To conclude, the AF reactor running under 24h HRT performs better than other conditions. In this case, it is due to the presence of 70% sponge bio-media in each compartment, which plays an important role in retaining suspended particles in the system. Furthermore, the initial attachment of sludge to sponge media may enhance the active microorganisms in the reactor, resulting in increased COD removal through organic digestion.

Published: August 2023

Abstract
Two-dimensional semiconducting transition metal dichalcogenides (TMDs) have attracted significant interest due to their unique optoelectronic properties. More often, these materials are enclosed inside a dielectric layer that can work as an insulator for field-effect transistors. The insulating layer is typically grown with atomic layer deposition (ALD). Here, we study the effects on bare and hBN-covered monolayer MoS2 and WSe2 flakes with ALD TiO2 films. Our results reveal a significant shift and decrease in intensity in photoluminescence and Raman signals of the monolayer TMDs. Further analysis suggests that these changes are caused by chemical doping, strain, and dielectric screening after the ALD. Our study not only sheds light on the impact of ALD on the properties of TMDs, but also indicates ALD can be an alternative method to engineer the doping, strain and dielectric environment for potential optoelectronics and photonics applications.

Abstract
Vat photopolymerization-based three-dimensional (3D) printing techniques have been used as an efficient method for complex and special geometries in various applications. Composites are also a group of polymer materials that are obtained by adding a reinforcing component such as filler, fibres with different origins. Therefore, the development of 3D printable composites is paramount due to their high precision and speed of production. Glass beads (GBs) have been favorites as economical reinforcement agents for their chemical stability, water resistance in acidic environments, dimensional stability, and eco-friendly properties. In this study, 3D printable composites based on coated glass beads (CGBs) have been prepared. First, the beads are coated with ultraviolet (UV) curable resins to improve the interface with the polymer matrix. Then, CGBs are mixed with 3D printing resin and formulated for digital light processing (DLP) printing. The coating process is checked by scanning electron microscopy (SEM), and the mechanical properties of the 3D-printed composite structures have been evaluated by bending and compression tests. Also, the fracture behavior of cured resin has been checked with SEM. Mechanical property investigations have shown the success of the 3D printing of the CGBs into a photopolymer resin (PR) composite with behavior modification and compatibility of the interface with the matrix in practice.

Abstract
We conducted a thorough analysis to assess the suitability of a T-graphene-like BC2N monolayer as an electrode material for sodium-ion batteries (NIBs) and potassium-ion batteries (KIBs) using first-principles calculations. Our investigation demonstrates the chemical adsorption of Na/K atoms onto the BC2N monolayer, which exhibits metallic properties after Na/K adsorption, ensuring excellent electrode conductivity. The average open-circuit voltages for Na and K are 0.39–0.12 V and 0.87–0.14 V, respectively. Furthermore, the BC2N monolayer revealed significantly lower Na/K diffusion barriers (0.40 eV for Na and 0.22 eV for K) and higher storage capacities (1647 mAh g−1 for Na and 2196 mAh g−1 for K) compared to conventional two-dimensional anode materials. These exceptional characteristics highlight the promising potential of the T-graphene-like BC2N monolayer in advancing Na/K-ion batteries technology.
