Voltage sag compensation at load side in armor fighting vehicles using ultra capacitor
Authors: N. Saravanan , S. Hosimin Thilagar 
Published: July 2022

Purpose
The purpose of this paper rapid development of various voltage sag compensation techniques in DC bus using ultra-capacitors (UCs) provides satisfactory results when compared with required peak power demand for shorter duration. Later, UCs have been used as floating capacitors [1] [2]. Various UCs are available based on internal resistances which also rely on its manufacturing materials, similar to double layer capacitors.

Design/methodology/approach
This paper demonstrates UCs based voltage sag compensation at load side under different working modes of hydraulic pack (HP) in an armored fighting vehicle (AFV). The main sources to supply the HP are 24 V, 400 Ahr battery bank and 20 kW main generator. HP is considered to be the highest power load of a system. 2,500 A inrush current was drawn by HP during initial conditions, and also, this system works in both elevation and azimuth mode. Voltage sag has been varied from 15 to 24 V for different modes. But as per the military standard, electrical systems should operate between 18 and 32 V DC. Because of insufficient terminal voltage, required energy cannot be attained and supplied to the loads. The proposed topology compensated the voltage sag and maintains nominal voltage on a DC bus. The devised circuit has been verified under all possible operating loads such as continuous, intermittent and momentary. The same has been simulated using MATLAB/Simulink and was experimentally verified. The minimum voltage maintained in a DC bus is 22.2 V in simulation, while experimentally, it was 24.2 V.

Findings
For getting higher percentage of efficiency, secondary energy system configuration, mainly designed for electrical vehicles, is needed. It was implemented and same was tested with the fighting vehicle system[1]. The proposed configuration comprises of bank of an UC and a battery bank. The system was finally implemented in AFVs.

Originality/value
The goods vehicles made of UCs can hold very minimum energy because of minimum density of energy. The modified AFV can have minimum charging as well as discharging of rate of energy and, thus, power[3][4]. Thus, the proposed idea of modified vehicle system has influence over significant change in the state of charge.

Flood hazards and housing prices: a spatial regression analysis for Hat Yai, Songkhla, Thailand
Authors: Chongwilaikasaem Sukampon , Chalermyanont Tanit 
Published: July 2022

Purpose
Global warming exacerbates sea level rise and extreme weather events that cause severe flooding, resulting in lost productivity and property damage. To reduce the impact of flooding, residents are avoiding purchasing homes in high-risk areas. There are numerous studies on the relationship between flood hazards and housing prices in developed countries, but few in developing countries. Therefore, this study aims to investigate the relationship between flood hazards and housing prices in Hat Yai, Songkhla, Thailand.

Design/methodology/approach
This study uses spatial-lag, spatial error and spatial autoregressive lag and error (SARAR) models to analyze the effect of flood risk on property prices. The main analysis examines the degree of flood risk and housing rental prices from our survey of 380 residences. To test the robustness of the results, the authors examine a different data set of the same samples by using the official property valuation from the Ministry of Finance and the flood risk estimated by the Southern Natural Disaster Research Center.

Findings
The SARAR model was chosen for this study because of the occurrence of spatial dependence in both dependent variable and the error term. The authors find that flood risk has a negative impact on property prices in Hat Yai, which is consistent with both models.

Originality/value
This study is one of the first to use spatial econometrics to analyze the impact of flood risk on property prices in Thailand. The results of this study are valuable to policymakers for benefit assessment in cost–benefit analysis of flood risk avoidance or reduction strategies and to the insurance market for pricing flood risk insurance.
The post-migration experiences and mental wellbeing of Shan men in Thailand: a qualitative study
Authors: Cashmore Aaron , Bhatarasakoon Patraporn , Haswell Melissa , Jalaludin Bin , Ritchie Jan 
Published: July 2022

Purpose
Hundreds of thousands of Shan people from Myanmar have crossed the Thai border seeking employment or refuge from war, with numbers increasing following the 2021 coup in Myanmar. Still, little is known about their post-migration experiences. This study explored the ways relocating to Thailand influenced the lives and mental wellbeing of Shan men, the factors affecting their engagement with Thai society and their responses to opportunities and challenges.

Design/methodology/approach
Given the lack of published research on this topic, this study used a qualitative approach. Semi-structured interviews were conducted with 14 purposively selected Shan men in Chiang Mai, Thailand. Data were examined using qualitative thematic analysis.

Findings
Five themes emerged: the strength of both push and pull factors; the importance of ethnicity, community and acting transnationally; experiencing discrimination and feeling “low”; coping by forgetting problems, hiding from trouble and studying; and wanting to return when conditions allow. The findings reveal how moving to Thailand can improve but also undermine the mental wellbeing of Shan men. Results also highlight the influence of ethnic identity, community and post-migration opportunities and stressors on how these men adapt to life in Thailand and on their attitudes towards return migration. Respondents used a mix of emotion- and problem-focused coping strategies.

Originality/value
To the best of the authors’ knowledge, this study is one of the first to explore post-migration experiences and mental wellbeing among the Shan in Thailand.
Earnings management in times of natural disasters
Authors: Rueangsuwan Sarayut , Jevasuwan Supavinee 
Published: July 2022

Purpose
The main purpose of this study is to examine the determinants of firms’ earnings management (EM) activities during natural disasters, specifically the 2011 floods in Thailand. The motivation for conducting this study is that although disasters stem from natural processes, such events affect firms’ actions, resulting in adverse economic and social outcomes.

Design/methodology/approach
Based on data from listed companies in Thailand and using a sample of 5,786 firm-year observations from 2008 to 2013, this study uses the differences-in-differences method to estimate the relation between earnings quality (EQ) and floods. Additionally, this study uses the same research design to observe how fast firms engage in EM, as reflected by the trends in EQ following the floods.

Findings
This study finds that firms engage in EM to increase their earnings numbers and misrepresent their performance after experiencing the 2011 floods in Thailand. The evidence is consistent with the hypothesis that natural disasters are related to EQ. In addition, this study finds that firms’ responses are observed only in the year after the floods (2012).

Originality/value
This study contributes to the literature on EM and quality in two ways. First, this study provides new evidence that during crisis situations such as natural disasters, firms strive to signal good news to capital markets, consistent with the market expectation hypothesis. Second, this study shows that natural disasters are as useful and equal as other exogenous shocks such as financial crises for economic research.
Façades as product wrap: a typology to identify the consumers affected by product design
Authors: Aljukhadar Muhammad 
Published: July 2022

Purpose
The elevation of a residential building, or façade, affords aesthetic and functional value to tenants. Façades embody the design of the core product, i.e. the building’s unit. When carefully executed, they contribute to the attractiveness, livability and sustainability of urban areas. The purpose of this study is to show how façades influence consumer decision, and to identify the consumers affected more by façades, i.e., product design.

Design/methodology/approach
Hinging on notions from product design and appearance, this research underscores the ways by which façades affect potential tenants. It also proposes that personality dimensions (i.e. concern with own physical appearance and view of achievement) identify the tenants affected more by façades. A study involving 1,091 consumers was performed to test the hypotheses.

Findings
Functional and aesthetic façades facilitated the tenant decision to buy or rent a living unit in three ways: attraction, convection and conversion. Two tenant segments (performers and egotists) were the most affected by façades. Hence, key consumer segments including self-actualizers would be less influenced by product design.

Practical implications
Construction companies should focus on delivering functional, aesthetic and well-maintained façades to boost satisfaction and sales. They should view the resources allocated to this purpose as an investment. Certain tenants are more affected by façades. Companies should identify the consumer segments more affected by design cues to better respond to their preferences. Policymakers are encouraged to set guidelines that foster well-executed façades in urban areas.

Originality/value
This research underscored the ways by which the façades of residential buildings shape consumer decision. In addition, it provided a typology to help pinpoint the tenants more affected by façades. Finally, it elaborated design theories in the context of residential building façades, which can be used by future researchers to understand the role of façade in fulfilling tenants’ needs and expectations.
CSR assurance practice and financial distress likelihood: evidence from India
Authors: Oware Kofi Mintah , Appiah Kingsley 
Published: July 2022

Purpose
The purpose of this study is to examine the effect of corporate social responsibility assurance practice (CSRAP) on the financial distress likelihood of listed firms in India. It uses the signalling theory to interpret the relationship among the variables of the study.

Design/methodology/approach
The study used the Indian stock market as the testing grounds and applied probit and panel probit regression to examine the data set with 800 firm-year observations from 2010 to 2019.

Findings
The study’s first findings show that firms with an assurance service have a negative correlation and are less likely to stay in financial distress situations for an extended period. However, corporate social responsibility (CSR) assurance has a positive but weak correlation with insignificance with financial distress likelihood of firms in India. The authors also find that the engagement of CSR assurance and level of assurance (limited assurance) does not cause a change in a firm financially distress likelihood of firms in India. However, as assurance service providers, auditing firms are more likely to reduce a firm’s likelihood of financial distress. Finally, the study shows that CSRAP (CSR assurance, assurance service providers and level of assurance) does not moderate the association between CSR expenditure and financial distress likelihood of listed firms in India.

Originality/value
The study findings are the first to examine the level of assurance and financial distress of firms according to the authors’ knowledge. This study also adds new knowledge to the factors that cause or reduces the financial distress of listed firms, including CSRAPs.
An improved parallel five-level reinjection CSC for self-commutation of thyristor converter
Authors: Song Yumei , Hao Jianzhang , Dong Changhao , Guo Xizheng , Wang Li 
Published: July 2022

Purpose
This paper aims to study a multi-level reinjection current source converter (MLR-CSC) that adds attracting properties such as the self-commutation and pulse multiplication to the thyristor converter, which is of great significance for increasing the device capacity and reducing current harmonics on the grid side. Particularly, designing advantageous driving methods of the reinjection circuit is a critical issue that impacts the harmonic reduction and operation reliability of the MLR-CSC.

Design/methodology/approach
To deal with the mentioned issue, this paper takes the five-level reinjection current source converter (FLR-CSC), which is a type of the MLR-CSC, as the research object. Then, a method that can fully use combinations of five-level reinjection switching functions based on the concept of decomposition and recombination is proposed. It is worthy to mention that the proposed method can be easily extended to other multi-level reinjection circuits. Moreover, the working principle of the three-phase bridge circuit based on semi-controlled thyristors in the FLR-CSC that can achieve the four-quadrant power conversion is analyzed in detail.

Findings
Finally, the simulation and experimental results of FLR-CSC verify the effectiveness of the proposed reinjection circuit driving method and the operating principle of four-quadrant power conversion in this paper.

Originality/value
The outstanding features of the proposed driving method for FLR-CSC in this paper include combinations of reinjection switching functions that are fully exploited through three simple steps and can be conveniently extended to other multi-level reinjection circuits.

Published: July 2022

AbstractThis all‐case postmarketing surveillance (PMS) survey (101 centers; February 15, 2017, to March 3, 2020) captured factors that impact the safety and effectiveness of newly initiated pembrolizumab monotherapy for the treatment of radically unresectable melanoma in Japan. Eligible patients were enrolled both retrospectively and prospectively, and followed up at 1, 3, 6, and 12 months. Safety assessments included treatment‐related adverse events (TRAEs), adverse events of special interest (AEOSIs) from the Japanese Risk Management Plan (J‐AEOSIs), and J‐AEOSIs related to pembrolizumab. Effectiveness assessments included objective response rate (ORR; complete response/partial response) and disease control rate (DCR) according to the RECIST criteria. Overall, 294 and 236 patients comprised the safety and effectiveness (RECIST) assessment sets, respectively. Median (range) age of the patients was 70 (22–94) years, and the majority (60.4%) received pembrolizumab as first‐line therapy. The most common type of melanoma was cutaneous (41.5%), followed by mucosal (29.3%), acral (24.8%), and unknown (4.4%). Overall, 45.2% and 24.8% of patients experienced TRAEs and AEOSIs, respectively. In total, 24.8% and 9.2% of patients experienced any‐grade and grade ≥3 pembrolizumab‐related AEOSIs, respectively. The most common grade ≥3 pembrolizumab‐related AEOSIs were endocrine disorders and liver dysfunction (2.4% each), followed by colitis/severe diarrhea (2.0%), interstitial lung disease (1%), and type 1 diabetes (0.7%). No grade 5 J‐AEOSIs were observed. ORR was 16.5% at the 1‐year follow‐up: mucosal melanoma (20%), acral melanoma (10%), and cutaneous melanoma (17.5%). ORR was higher among patients who did not receive versus those who did receive previous systemic therapy across all three melanoma types. DCR was 52.1% at the 1‐year follow‐up: cutaneous melanoma (57.3%), acral melanoma (51.7%), and mucosal melanoma (43.1%). This all‐case PMS survey confirmed the real‐world safety and effectiveness of pembrolizumab monotherapy for the treatment of radically unresectable melanoma in Japan.
Scaling effects of temperature on parasitism from individuals to populations
Authors: Kirk Devin , O'Connor Mary I. , Mordecai Erin A. 
Published: July 2022

Abstract

Parasitism is expected to change in a warmer future, but whether warming leads to substantial increases in parasitism remains unclear. Understanding how warming effects on parasitism in individual hosts (e.g. parasite load) translate to effects on population‐level parasitism (e.g. prevalence, R0) remains a major knowledge gap.

We conducted a literature review and identified 24 host–parasite systems that had information on the temperature dependence of parasitism at both individual host and host population levels: 13 vector‐borne systems and 11 environmentally transmitted systems.

We found a strong positive correlation between the thermal optima of individual‐ and population‐level parasitism, although several of the environmentally transmitted systems exhibited thermal optima >5°C apart between individual and population levels. Parasitism thermal optima were close to vector performance thermal optima in vector‐borne systems but not hosts in environmentally transmitted systems, suggesting these thermal mismatches may be more common in certain types of host–parasite systems.

We also adapted and simulated simple models for both types of transmission modes and found the same pattern across the two modes: thermal optima were more strongly correlated across scales when there were more traits linking individual‐ to population‐level processes.

Generally, our results suggest that information on the temperature dependence, and specifically the thermal optimum, at either the individual or population level should provide a useful—although not quantitatively exact—baseline for predicting temperature dependence at the other level, especially in vector‐borne parasite systems. Environmentally transmitted parasitism may operate by a different set of rules, in which temperature dependence is decoupled in some systems, requiring the need for trait‐based studies of temperature dependence at individual and population levels.
Floral biology, breeding system and pollination ecology of Justicia betonica L. (Acanthaceae): An assessment of its low reproductive success in West Bengal, India

Published: July 2022

AbstractBesides its importance as an ornamental plant, Justicia betonica L. is also used as a medicinal plant for the treatment of several human disorders. However, the population size and abundance of the plant species are very low in Indian states, including West Bengal. The breeding system and pollination ecology of J. betonica are still unclear. Therefore, some reproductive aspects were investigated in order to provide important information for the sustainability of the species. The flowering duration spanned from December to May, with its peak in February–March. Flower opening time was much earlier (5.00–8.00 a.m.) on a hot day (in April–May) than on a cold day (10.00 a.m.–12.00 p.m. in December–January). The time of anther dehiscence coincided with the flower opening time; however, the stigma became receptive later. The plant species is self‐compatible but dependent on pollinators for fruit and seed sets. Members of different insect groups like ants, bees, butterflies, flies, moths and wasps visit the flowers. Among them, Allorhynchium metallicum and Halictus acrocephalus are the primary pollinators (based on the “relative pollinator service”). The plant species showed a significant pollination deficit (coefficient of pollination deficit [D] = 0.32) in the open condition. Larvae of the florivorous moth Gatesclarkeana erotias significantly reduced reproductive success by eating their floral parts, ovules and immature seeds. In conclusion, combining the pollination deficit and the feeding activity of phytophagous insects (moth larvae) may reduce the reproductive fitness of J. betonica in the study regions.
Moth sex pheromones affect interspecific competition among sympatric species and possibly population distribution by modulating pre‐mating behavior
Authors: Cheng Jianjun , Chen Qinghua , Guo Qianshuang , Du Yongjun 
Published: July 2022

AbstractPremating behaviors mediated by pheromones play pivotal roles in animal mating choices. In natural populations of the striped stem borer Chilo suppressalis and the rice leaf roller Cnaphalocrocis medinalis in the rice field habitat, we discovered that Z11‐16:Ald, a major component of the C. suppressalis pheromone, modulated the premating behavior of C. medinalis. Z11‐16:Ald evoked a strong olfactory response in male antennae and strongly inhibited the sex pheromone trapping of male C. medinalis in the field. The functions of three C. medinalis sex pheromone receptor genes (CmedPR1–3) were verified through heterologous expression in Xenopus oocytes. CmedPR1 responded to Z11‐18:OH and Z11‐18:Ald, as well as the interspecific pheromone compound Z11‐16:Ac of sympatric species; CmedPR2 responded to Z13‐18:OH and Z13‐18:Ald, as well as the sex pheromone compounds Z11‐16:Ald and Z9‐16:Ald of sympatric species; and CmedPR3 responded to Z11‐18:OH and Z13‐18:OH, as well as the interspecific pheromones Z11‐16:OH, Z9‐16:Ald, Z11‐16:Ac, and Z11‐16:Ald of sympatric species. Thus, CmedPR2 and CmedPR3 share the ligand Z11‐16:Ald, which is not a component of the C. medinalis sex pheromone. Therefore, the sex pheromones of interspecific species affected the input of neural signals by stimulating the sex pheromone receptors on the antennae of male C. medinalis moths, thereby inhibiting the olfactory responses of the male moths to the sex pheromones. Our results demonstrate chemical communication among sympatric species in the rice field habitat, the recognition of intra‐ and interspecific sex pheromones by olfactory receptors, and how insect premating behaviors are modulated to possibly affect resource partitioning.
