Authors: Ahmadani Faisal , Amedeo Alfa D. , Sutisna Muhammad , Nugrahani Henny S. D. , Masfufah Yulinar A.
Published: April 2021

The service sector is a sector that is increasingly playing a large and essential role in many countries, including Indonesia. Currently, the service sector contributes more than 45% of the economic value-added and absorbs more than 35% of the workforce. Nevertheless, the service sector’s critical role in the economy comes from the direct impact of the service sector through its proportion to GDP or labor statistics and its role as an intermediate input and enabler for all economic activity. Even since the economic crisis that hit Asia several decades ago, the service sector has helped the Indonesian economy a lot. During the Covid-19 pandemic, several service sectors experience a sharp slowdown, like tourism and hospitality. Nevertheless, some sectors play an essential role in controlling and stabilize the situation like medical and economy. This study aims to determine why the service sector is considered one of the most affected by the Covid-19 pandemic and the possible solution for each sub-sector as a community initiative.

Authors: Rodhiya Fahima I , Parahyanti Endang , Radikun Tulus B S
Published: April 2021

Due to the current financial instability worldwide, maintaining business growth requires continuous breakthroughs and innovations. It means that millennials, the current majority of the workforce, need to be innovative instead of feeling insecure about their jobs in this uncertain economic condition. Job insecurity prevents millennials from performing innovative work behavior (IWB) because employees tend to avoid time-consuming activities to generate creative ideas when they are insecure about their jobs. Thus, this study examines the negative effect of job insecurity on innovative work behavior. Given the importance of innovative work behavior, it is worth to find possible ways to minimize the negative effect of job insecurity on IWB. Therefore, this study tried to explore whether flexible working arrangement (FWA) could buffer the negative impact of job insecurity on innovative work behavior. The results showed that the negative effect of job insecurity on IWB would be reduced when the FWA is high. In other words, the negative effect of job insecurity on IWB in low FWA condition (r = -.37; p < .01) became insignificant in high FWA condition (r = -.01, n.s.).
Policy on optimization of household waste and hazardous waste management based on community empowerment at the local level
Authors: Brotosusilo Agus , Naldi Ari
Published: April 2021

Central Bureau of Statistics (BPS) survey in 2018 showed that only 1.2% of households recycle waste and around 66.8% incinerate waste. Low community participation has a negative impact on landfill dependence, managing-cost, sustainable waste management, and the environment. This study aims to optimize community-based household and hazardous waste management at the local government level. This research used policy analysis, field surveys, and in-depth interviews regarding the issuance of Jakstrada. However, Jakstrada is not necessarily the answer to the waste problem. This is in accordance with the target to be achieved from the preparation of the Jakstrada, whereby in 2025 the national waste problem is 100% managed, with no more waste being dumped into the river or open burning in the environment. Waste is encouraged to be managed by applying the 3R (reduce-reuse-recycle) principle, with the key strategy by changing the community’s paradigm to build awareness in managing their waste. As the hierarchy of sustainable waste management emphasizes the importance of public participation and changes their perception of waste management as the first step to achieve waste reduction, support for reliable technology is also needed to recycle and reuse waste.
Vulnerable people and sustainable livelihoods in the face of replanting phase in oil palm industry in Jambi - Sumatra
Authors: Anwar Mokhamad Zainal , Sunesti Yuyun
Published: April 2021

This article aims to discuss the threat of vulnerability in the oil palm industry-based village. This vulnerability occurs because oil palm which has been the source of people’s livelihoods has to be uprooted and replanted. Among the social structures of the village community, the most vulnerable are local farmers and plantation workers who do not own land and the work in oil palm plantations has been their main job. The data collection in this paper was conducted using document study techniques, focus group discussions, in-depth interviews and observations from the end of December 2016 to January 2017. This paper has two main findings: firstly, the main source of livelihood for the community relies on oil palm plantations, but it is limited to producing fresh fruit bunches and they have not been able to process any further because the palm oil is transferred to the plantation company. If replanting is to be carried out, the residents’ main source of livelihood will be automatically threatened. Secondly, the most vulnerable community groups are the second generation and so on, where they do not have land for gardening and can only work as farm laborers or work in plantation companies.
The effect of audit tenure on information asymmetry: Investigating the role of auditors in achieving a more transparent organization (Target 16.6 SDGs)
Authors: Primadita Indria , Fitriany Fitriany , Kiantara Rio F
Published: April 2021

One of the SDGs targets is the achievement of transparency of the organization. Information asymmetry is a condition in which management’s information is not in balance with shareholders/stakeholders. This study also investigates whether specialist auditors can reduce information asymmetry. Regression analysis using 274 observations of financial data from firms listed on the Indonesia Stock Exchange, this research finds that the audit tenure relationship and information asymmetry are u-shaped (a quadratic relationship) with a minimum point at eight years. These results indicate that, in the early years of the audit engagement, the longer a public accounting firm audits a company (tenure), the information asymmetry will decrease. These results indicate that after eight years, the bonding between auditors and clients is getting more robust so that auditors find it difficult to maintain their independence. After eight years, it is necessary to change (rotate) the public accounting firm that audits a company because its independence begins to decline. These results indicate that public accountants have played a significant role in achieving a more transparent and accountable organization, as one of the SDGs’ goals.
Factors that affect dysfunctional audit behaviour: A study to understand external auditor’s role as the guardians of strong and justice organizations (Goal 16 sustainable development goals)
Authors: Prabangkara Sungging , Fitriany Fitriany
Published: April 2021

This study aimed to investigate factors that affect dysfunctional audit behavior, represented by audit quality reduction and underreporting time. Using 117 questionnaires distributed to auditors in Jakarta, a multiple regression analysis is performed to test the hypothesis. The results showed that perceived time budget pressure and continuous professional commitment positively influence audit quality reduction and underreporting time. While professional commitment, affective, type of personality, and auditor position in audit firms negatively affect audit quality reduction and underreporting time. Besides, competencies negatively affect audit quality reduction and do not affect the underreporting of time. On the other hand, normative professional commitment and independence do not affect audit quality reduction and underreporting time. These results indicate that public accountants have played a role in achieving a more transparent and accountable audit firm, SDGs goals no 16.

Published: April 2021

Green open spaces have many functions and positively impact urban communities, both psychologically and physically. Students spend most of their time in the campus area like gardens, but their perspectives are less involved in planning campus gardens as the user of the garden. The condition of the garden as one of the environmental factors depends on the behavior of garden users. On the other hand, the condition of the garden forms the behavior and perspectives of garden users. It is crucial to know users’ needs to ensure the sustainability of users’ behavior and gardens’ condition. Based on these problems, this study aims to understand users’ perceptions and problems on-site, create a conversation between stakeholders. Questionnaire results were obtained from 36 active garden users by using a purposive sampling method. The results were analyzed descriptively. The questions were divided into three sections regarding users’ cognitive, environmental, and behavioral factors—the results actors, user perspectives, and user behavior that are interdependent and form one another. Universities need to start a conversation concerning users’ needs in the campus garden to sustain its condition and a better campus community.

Authors: Laith A A
Published: April 2021

Rhizophora apiculata leaf extracts were tested on the isolated growth of S. agalactiae and E. coli and extraction of the bioactive compounds were performed using Soxhlet extraction technique with methanol (MtOH) as the organic solvent. The presence of various phytochemicals in bioactive constituents of the plant was detected using standard chemical procedures. The Kirby-Bauer test was used for the antibacterial assay, and an in vitro assay was conducted for minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC). Brine shrimp lethality assay evaluated the toxicity of R. apiculata. Antibiotic susceptibility test showed high rates of E. coli resistance to neomycin and sensitivity to tetracycline and amoxycilin, while S. agalactiae showed sensitivity to all antibiotics. Inhibition zones of R. apiculata leave extract against the microorganisms recorded in the range of 2-9 mm. Increasing the inhibition zone is dependent on increasing plant extract concentrations. The (MIC) testing range of R. apiculata was 6.25 mg/ml to 12.5 mg/ml against S. agalactiae and E. coli, respectively. The MBC/MIC ratio of S. agalactiae demonstrated to be bactericidal, and the MBC/MIC ratio of E. coli was bacteriostatic. R. apiculata recorded an LC50 value of 81 mg/ml. The findings of this study reveal the valuable metabolites found in mangrove leaves. The most important secondary metabolites are alkaloids, terpenoids and tannins as well as saponins and steroids, but not flavonoids. This study suggests that Rhizophora apiculata has the potential to be a valuable candidate in the discovery of antimicrobial compounds against fish pathogens.

Authors: Itoh Takafumi
Published: April 2021

Chitin and its derivatives have valuable potential applications in various fields that include medicine, agriculture, and food industries. Paenibacillus sp. str. FPU-7 is one of the most potent chitin-degrading bacteria identified. This review introduces the chitin degradation system of P. str. FPU-7. In addition to extracellular chitinases, P. str. FPU-7 uses a unique multimodular chitinase (ChiW) to hydrolyze chitin to oligosaccharides on the cell surface. Chitin oligosaccharides are converted to N-acetyl-d-glucosamine by β-N-acetylhexosaminidase (PsNagA) in the cytosol. The functions and structures of ChiW and PsNagA are also summarized. The genome sequence of P. str. FPU-7 provides opportunities to acquire novel enzymes. Genome mining has identified a novel alginate lyase, PsAly. The functions and structure of PsAly are reviewed. These findings will inform further improvement of the sustainable conversion of polysaccharides to functional materials.

Published: March 2021

The Kisspeptin/Kiss1r system is a key regulator of reproduction by stimulating gonadotrophin-releasing hormone and luteinizing hormone release, and in vitro studies have shown that Kisspeptin can modulate angiogenesis and immune function, factors that are also essential for reproduction However, there are no studies on the expression of Kisspeptin/Kiss1r at the maternal-fetal interface in domestic cats and its relationship with angiogenic and immunological mediators. Thus, our objective was to evaluate the spatiotemporal expression profile of Kisspeptin/Kiss1r and angiogenic and immunological mediators in the uterus and placenta of domestic cats during pregnancy. Uterus and placenta samples were collected from cats in mid pregnancy (N = 6) and late pregnancy (N = 6), in addition to uterus from non-pregnant cats in diestrus (N = 7), to evaluate protein and gene expression of kisspeptin (Kiss1), kisspeptin receptor (Kiss1r), vascular endothelial growth factor (VEGF), tyrosine kinase receptor (Flk-1), placental growth factor (PLGF), interferon gamma (INFγ), migration inhibiting factor (MIF), tumor necrosis factor (TNFα), interleukins (IL6 and IL10) by immunohistochemistry and quantitative polymerase chain reaction. Pregnancy increased the uterine expression of Kiss1 and Kiss1r, especially at the late pregnancy, in addition to upregulating INFy, MIF, Vegf, Il10, and Tnf and downregulating Plgf. Higher placental expression of Kiss1r and Plgf mRNA occurred at the late pregnancy, while the expression of Kiss1, VEGF, Flk-1, INFy, TNFα, Il6, and IL10 was higher in the mid of pregnancy. A positive correlation between Kiss1 and Tnf was observed in the placenta, while Kiss1r had a negative correlation with Infγ, Il6, and Il10. The findings reveal that Kisspeptin/Kiss1r and angiogenic and immunological mediators at the maternal-fetal interface of pregnant cat have a gene correlation and are modulated by the gestational age. These data suggest possible functional links of Kisspeptin in placental angiogenesis and immunology.
Telenutrition for Inflammatory Bowel Disease: A Tipping Point for Dietary Wellness
Authors: Elamin Sami , Cohen Jonah
Published: April 2021

Inflammatory bowel disease (IBD), Crohn’s disease and ulcerative colitis, cause inflammation of the digestive tract. It is estimated that about three million Americans and, globally, over six million individuals, suffer from IBD. While most physicians, especially gastroenterologists, are experts in the function and pathology of the gastrointestinal tract, factors such as nutrition science education and training, bandwidth, culture, language, and the longitudinal nature of dietary care, represent some of the barriers to receiving optimal nutritional guidance. Remote dietary expert counseling, an emerging solution that has been further highlighted by the COVID-19 pandemic, can improve IBD patients’ nutritional status, avoid food triggers, and reduce the frequency and severity of exacerbations.
Mi china juventud: Childhood and Hybrid acts in Cuéntame cómo pasó
Authors: May Delphi Pearl
Published: March 2021

Since 1990, Spain has taken in over 200,000 Chinese immigrants. With these citizens often the targets of racist attacks and stereotypes, several filmic and televisual texts offer stereotypical representations of Chinese immigrants either as violent or as a model minority. Nevertheless, texts are emerging that offer more nuanced representations of this migrant body and construct complex characters whose identity struggles form part of Spain’s socio-cultural fabric. Cuéntame cómo pasó (La1, 2001 – present) is one of the first Spanish television programmes to represent a Spanish-Chinese immigrant child this way. This article analyses the Spanish-Chinese immigrant child’s construction within public service broadcasting, arguing that her character’s representation is informed by the channel’s public service responsibility. The analysis considers the notion that her character is the generator of ‘hybrid acts’ and is an agent of cross-cultural contact in her friendship group.

OBJECTIVES

Tracheobronchomalacia (TBM) is characterized by collapse of trachea, bronchi or both, leading to dyspnoea, expiratory stridor, coughing or recurrent airway infections. Surgical treatment with aortopexy is warranted for severe TBM. We describe a modified aortopexy technique with aortic wall strap sutures that evenly distributes the traction force over the full width of the aortic arch. The aim of this study was to determine the outcomes of this modified anterior aortopexy technique.

METHODS

Retrospective chart review of all patients undergoing aortopexy with aortic wall strap sutures for TBM between January 2010 and June 2020 in 2 tertiary hospitals in the Netherlands.

RESULTS

Twenty-four patients [median age 9 months (interquartile range 2–117 months); 71% male] underwent aortopexy with the modified technique for TBM (52%), tracheomalacia (40%) or bonchomalacia (8%). Aortopexy was successful in 91.7%, defined as relief or decrease of respiratory symptoms and no need for respiratory support. Complications occurred in 8.3% and mortality was 4%.

CONCLUSIONS

Aortopexy with non-absorbable strap sutures seems an effective and safe treatment for severe TBM. This study supports the hypothesis that strap sutures provide a solid and reliable traction force, but future comparative studies should confirm the benefit of strap sutures over conventional techniques.

OBJECTIVES

We sought to explore the efficacy of the endovascular repair of an ascending aortic aneurysm with aortic and mitral regurgitation by 2 novel valved stents.

METHODS

We established models of ascending aortic aneurysms combined with aortic and mitral regurgitation in 10 pig hearts, then implanted self-expanding aortic fenestrated and mitral valved stents via the transapical approach. We applied a fluoroscopy-guided in vitro setting to test the approach, then analysed continuous circulating flushing at 37°C. Finally, we determined operating times, echocardiography and changes of coronary flow as well as fenestration alignment with the coronary ostia.

RESULTS

This approach resulted in a 100% overall technical success rate, excellent handling properties and precise positioning. The time taken to implant the 2 valved stents was 59 ± 12 min. Flow of the left and right coronary arteries did not significantly decrease after the stents were implanted (330.4 ± 12.06 ml/min vs 289.4 ± 5.29 ml/min, P < 0.001; 376.8 ± 10.5 ml/min vs 350.0 ± 14.5 ml/min; P < 0.001). We found no obvious regurgitation and perivalvular leakage; nor did the gradients of the aortic and mitral valves as well as of the left ventricular outflow tract increase significantly. The final angiographic examination and profile of the coronary opening confirmed the good position of the valved stents, the exclusion of the aneurysm and the patency of both coronary arteries.

CONCLUSIONS

These findings indicate the potential for combined transcatheter aortic root and mitral valve replacement in treating aortic root pathologies. In future, in vivo studies are expected to validate this approach and ascertain its durability.

OBJECTIVES

To determine the incidence of bioprosthetic structural valve deterioration in dialysis patients undergoing aortic valve replacement compared to that in patients without dialysis.

METHODS

This single-centre retrospective observational study included 1159 patients who underwent aortic valve replacement using bioprosthetic valves for aortic stenosis and/or regurgitation at our institution between 2007 and 2017 [patients with dialysis (group D, n = 134, 12%) or without dialysis (group N, n = 1025, 88%)]. To adjust for potential differences between groups in terms of initial preoperative characteristics or selection bias, a propensity score analysis was conducted. The final sample that was used in the comparison included 258 patients, as follows: 129 patients with dialysis (group D) and 129 patients without dialysis (group N). The cumulative incidences of all-cause death, cardiac death and moderate or severe structural valve deterioration were estimated using the Kaplan–Meier method.

RESULTS

Operative mortality was significantly higher in group D than group N (9% vs 0%, P = 0.001). Kaplan–Meier analysis revealed that in group D, the incidence was significantly higher for all-cause death (P < 0.001, 50% vs 18% at 5 years), cardiac death (P = 0.001, 18% vs 5% at 5 years) and moderate or severe structural valve deterioration (P < 0.001, 29% vs 5% at 5 years) compared with group N.

CONCLUSIONS

The incidence of structural valve deterioration in dialysis patients undergoing aortic valve replacement was higher than that in patients without dialysis. Bioprosthetic valves should be carefully selected in dialysis patients undergoing aortic valve replacement.
Quadratic Hecke Sums and Mass Equidistribution
Authors: Nelson Paul D
Published: March 2021

We consider the analogue of the quantum unique ergodicity conjecture for holomorphic Hecke eigenforms on compact arithmetic hyperbolic surfaces. We show that this conjecture follows from nontrivial bounds for Hecke eigenvalues summed over quadratic progressions. Our reduction provides an analogue for the compact case of a criterion established by Luo–Sarnak for the case of the non-compact modular surface. The novelty is that known proofs of such criteria have depended crucially upon Fourier expansions, which are not available in the compact case. Unconditionally, we establish a twisted variant of the Holowinsky–Soundararajan theorem involving restrictions of normalized Hilbert modular forms arising via base change.
Talking about Death, Becoming Buddhist Families: A Case Study of Religious Parenting Education in Contemporary Taiwan
Authors: Heller Natasha
Published: March 2021

Religious belief and practice affect how parents engage their children; the experience of parenting, in turn, can reshape religious ideas. Religious parenting resources serve to guide parents’ understanding of their relationship with their children and provide an important perspective on the family as a site of religious practice. Taking a special issue of a Taiwanese Buddhist journal as a case study to examine parenting strategies around the topic of death, I argue that conversations with their children about death provide parents an opportunity to re-write traditional scripts around death. Discussions around death also serve to re-orient the parent-child relationship to give greater weight to the child’s voice, and offer space for the parent to learn as well. These religious parenting materials provide new Buddhist perspectives on death and on how parents and children should relate.

Introduction

Patient-reported outcomes are important for burn injury research and clinical practice. The PROMIS-29 profile has been validated for use in diverse populations and numerous conditions, though not among people living with burn injuries. The purpose of this study was to examine validity and reliability of PROMIS-29 scores in adults with burn injury.

Methods

Data were provided by adult burn survivors participating in a multi-center longitudinal study of outcomes after burn injury. The PROMIS-29 Profile, which includes 4 items for each domain of physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles, and pain interference, was evaluated for validity and reliability. Floor and ceiling effects, unidimensionality, internal consistency, and reliability were examined. Differential item functioning (DIF) with respect to age, sex, education, race, ethnicity and burn size was assessed using ordinal logistic regression models and McFadden’s pseudo R2-change of ≥2% as critical value. Correlations with other measures (Community Integration Questionnaire, Satisfaction with Life Scale, Post-Traumatic Stress Checklist-Civilian, and Veteran’s Rand-12) and known group differences were examined to assess validity.

Results

876 burn survivors with moderate to severe injury from 6 months-20 years post burn provided responses on PROMIS-29 domains. Participant ages ranged from 18–93 years at time of assessment; mean years since injury was 3.4. All PROMIS-29 domains showed high internal consistency (Cronbach’s α=0.87–0.97). Substantial portions of the sample reported no symptoms (anxiety [42.6%], depression [50.9%], fatigue [26.3%], pain [47.7%]). There was a large ceiling effect on social roles (39.7%) and physical function (43.3%). One-factor confirmatory factor analyses supported unidimensionality for all domains (all CFI >0.95). We found no bias (DIF) across any demographic or clinical groups. Reliability was high (>0.9) across trait levels for all domains except sleep, which reached moderate reliability (>0.85). Known-group differences by demographic and clinical characteristics performed as hypothesized except burn size categories, which showed no significant relationship with PROMIS-29 physical function, fatigue, and pain interference scores.

Conclusions

The results provide strong evidence of reliability and validity of PROMIS-29 scores among adult burn survivors. Reliability of the extreme scores can potentially be increased and the ceiling effects reduced by administering PROMIS-43, which includes 6 items per domain.
