Designing nickel smelter industry investment competitiveness policy in Indonesia through system dynamics model
Authors: Hanafi Muhammad 
Published: May 2024

Purpose
This research is intended to assess the nickel smelter industry’s investment competitiveness in Indonesia and identify ways to improve its competitive advantage for the nation.

Design/methodology/approach
This research uses a sequential mixed-methods approach, expanding on a first qualitative phase with a second quantitative phase. Interviews are used in the qualitative phase to identify the underlying causes of issues and potential solutions to increase the competitiveness of the nickel smelter industry, while a system dynamics (SD) model is used to conduct the quantitative phase. This study uses the idea of a country’s competitive advantage from Porter’s diamond model (PDM). The model was tested and validated using SD simulation resulting in a new policy scenario, which was evaluated in metallurgy expert conferences and high policymaker discussion forums.

Findings
The results reveal the complexity of the nickel smelter industry in Indonesia and conclude that the integrated export duty beneficence policy is the most effective way to boost competitiveness. This policy gives a significant improvement both in the number of smelters and state revenue compared to the current policy. The industry’s investment competitiveness is enhanced by the six factors of the diamond model, with the first three factors being integrated strategy, limited export of excess production and export duty beneficence, while the remaining factors are metal price fluctuation, domestic demand and mineral supply which are related to mining conditions uncertainty.

Research limitations/implications
The research creates a SD model to support Indonesia’s competitive advantage in the smelter industry. Despite limitations like interpretations and distorted semantic analysis, it provides a useful framework for exploring complex industry themes, excluding social factors due to limited data and knowledge requirements.

Practical implications
The findings of this research offer a framework for policymaking by the government to enhance the competitiveness of investments in Indonesia’s nickel smelter industry.

Originality/value
This study delves into Indonesia’s nickel industry competitiveness using PDM. Using a more detailed SD model with quantitative analysis, it goes beyond strategy development to provide a comprehensive approach to the nickel smelter industry.

PurposeThis study aims to evaluate the nutrient content and acceptable qualities of plant-based burger patties (PBBP) formulated with chickpea flour, defatted sesame cake (DSC) flour, coffee silver skin and pomegranate juice as colorant.Design/methodology/approachThe chemical composition, energy value, cholesterol content, amino acid composition, cooking loss, pH, color characteristics and sensory attributes of PBBP were analyzed using official procedures and compared to beef burger. FindingsPBBP had a protein value of 16.0 g/100g, which is nearly close to the protein content of the beef burger (18.1 g/100g). The fat content of the PBBP was approximately three times lower than that of the beef burger. The fiber content in PBBP was approximately 23 times as high as that in beef burgers samples (p= 0.05). The raw PBBP samples supplies 178 Kcal/100g, whereas beef burger possessed 259 Kcal/100g. Neither the raw nor the cooked PBBP samples contained any cholesterol. Both the beef and PBBP displayed acceptability scores higher than 7.0, which suggests that PBBP was well accepted.Originality/valueIt is concluded that the PBBP sample exhibited a protein value of 16.0 g/100g, which is comparable to the protein level of beef burgers (18.1 g/100g). The fat level of the PBBP samples was significantly lower than that of the beef burger samples. Uncooked PBBP samples contained significantly higher fiber content compared to beef burger samples. No cholesterol was found in raw or cooked PBBP samples. Overall acceptance scores for both beef and PBBP samples exceeded 7.0, suggesting that the proposed product (PBBP) was received favorably.

Published: May 2024

PurposeThis study investigates how compulsory citizenship behaviors (CCB) affect employees’ energy and motivation to engage in other voluntary behaviors, such as service-oriented citizenship behavior and creativity. Specifically, we explore how employees’ perceptions of job overload mediate this relationship, based on their generational differences.Design/methodology/approachThis study employed a time-lagged survey design to collect data from 265 frontline employees and their supervisors in Pakistani-based organizations. The data was collected in three rounds, with a three-week gap between each round.FindingsThe findings suggest that role overload, resulting from compulsory citizenship pressure, undermines millennial employees' service-oriented organizational citizenship behavior (OCB) and creativity. However, these negative effects are less salient among non-millennials.Practical implicationsThe findings of this study provide valuable insights for managers, emphasizing the importance of exercising caution when imposing excessive citizenship pressures on employees against their will. In addition, organizations and human resource (HR) managers should consider devising policies for formal recognition of voluntary behaviors that contribute to organizational effectiveness.Originality/valueThis study contributes to existing CCB research by unraveling the previously unexplored mediating role of role overload and the contingency role of generational difference in explaining how and when coerced citizenship demands hinder employees’ propensity to engage in service-oriented OCB and creativity.

AbstractFusarium wilt of bananas (FWB) is a severe plant disease that leads to substantial losses in banana production worldwide. It remains a major concern for Cuban banana cultivation. The disease is caused by members of the soil‐borne Fusarium oxysporum species complex. However, the genetic diversity among Fusarium species infecting bananas in Cuba has remained largely unexplored. In our comprehensive survey, we examined symptomatic banana plants across all production zones in the country, collecting 170 Fusarium isolates. Leveraging genotyping‐by‐sequencing and whole‐genome comparisons, we investigated the genetic diversity within these isolates and compared it with a global Fusarium panel. Notably, typical FWB symptoms were observed in Bluggoe cooking bananas and Pisang Awak subgroups across 14 provinces. Our phylogenetic analysis revealed that F. purpurascens, F. phialophorum, and F. tardichlamydosporum are responsible for FWB in Cuba, with F. tardichlamydosporum dominating the population. Furthermore, we identified between five and seven distinct genetic clusters, with F. tardichlamydosporum isolates forming at least two subgroups. This finding underscores the high genetic diversity of Fusarium spp. contributing to FWB in the Americas. Our study sheds light on the population genetic structure and diversity of the FWB pathogen in Cuba and the broader Latin American and Caribbean regions.
Monetary policy and wealth inequality
Authors: Jackson Kieren 
Published: May 2024

AbstractThis thesis examines how monetary policy shocks affect wealth inequality in Australia. I analyse how a monetary policy shock, through asset price responses, affects household balance sheets and wealth inequality measures. I find that contractionary monetary policy reduces the wealth gap, but also disproportionately increases the wealth share of the most affluent Australians. This is driven largely by the response of house prices to an increase in the central bank's policy rate. I use a novel methodology to overcome the data limitations that usually impede studies of wealth inequality, and I produce results with implications for central bankers and policymakers. My results are robust to numerous lag specifications, modelling techniques and identification strategies.
A dynamic model of resource extraction and intensity of competition
Authors: Pegna Tim 
Published: May 2024

AbstractThis paper represents a significant extension of the traditional Cournot extraction game, by introducing the linear supply function strategy space in a novel, dynamic way. A variety of asymmetric cases are considered, including the new firm‐specific competitive strategies. The results highlight the importance of competition in accelerating the supply of critical minerals, which is vital to mitigate climate change, but also present a new sustainability challenge.
Do central banks respond to house price movements? A Bayesian DSGE approach
Authors: Li Longcan 
Published: May 2024

AbstractThis thesis explores whether monetary policy reacts to house price movements, by employing a New Keynesian model with a housing factor and estimated using Bayesian estimation techniques. The primary emphasis of this study is on the United States, with supplementary analyses on central banks in several advanced economies. The principal finding of this thesis reveals that the Federal Reserve responded substantially but episodically to house prices. Furthermore, my investigation indicates that the Reserve Bank of Australia, the Reserve Bank of New Zealand, Bank of England, and the European Central Bank did not incorporate house prices into their policy framework, whereas the Bank of Canada did so episodically. The baseline results remain robust across a range of sensitivity checks.
The impact of unions on the Australian enterprise bargaining framework
Authors: Morton William 
Published: May 2024

AbstractThis paper explores the effects of union involvement in enterprise bargaining agreements (EBAs) on non‐wage outcomes. My research is carried out through using a dataset of all federal EBAs in Australia from 1997 to 2021 and utilises fixed effects regressions. An index was constructed of 10 variables to capture a comprehensive overview of non‐wage outcomes. This paper finds that union involvement in an EBA, on average, is associated with a 0.494 unit increase in the index, or a 13.5% increase on the average index score. Overall, these results provide further insight into union impacts on the labour market within the enterprise bargaining framework.
Evaluating Australia's financial conditions: A comparative analysis and extension of a dynamic factor model index
Authors: Khreish Alexander 
Published: May 2024

AbstractThis article investigates the unique financial conditions in Australia in the wake of COVID‐19, a subject of critical importance given the recent unprecedented economic events such as the fastest rate rises since the 1990s and the presence of persistently high inflation. This study aims to contribute to the literature by examining the speed of interest rate changes and its implications on financial conditions, particularly in an environment characterised by negative real interest rates. The research aims to extend and refine the financial conditions index (FCI) developed by the Reserve Bank of Australia by incorporating a momentum variable to capture the speed of interest rate changes. A dynamic factor model is utilised to investigate 73 data series across nine main categories, constructing the FCI on a quarterly basis. The results indicate that rapid interest rate changes significantly impact financial conditions, holding significant weights within the model, thus requiring careful policy considerations.

Published: May 2024

AbstractGlycomacropeptide (GMP) is a bioactive peptide derived from whey protein, consisting of 64 amino acids. It is a phenylalanine‐free peptide, making it a beneficial dietary option for individuals dealing with phenylketonuria (PKU). PKU is an inherited metabolic disorder characterized by high levels of phenylalanine in the bloodstream, resulting from a deficiency of phenylalanine dehydrogenase in affected individuals. Consequently, patients with PKU require lifelong adherence to a low‐phenylalanine diet, wherein a significant portion of their protein intake is typically sourced from a phenylalanine‐free amino acid formula. GMP has several nutritional values, numerous bioactivity properties, and therapeutic effects in various inflammatory disorders. Despite all these features, the purification of GMP is an imperative requirement; however, there are no unique methods for achieving this goal. Traditionally, several methods have been used for GMP purification, such as thermal or acid treatment, alcoholic precipitation, ultrafiltration (UF), gel filtration, and membrane separation techniques. However, these methods have poor specificity, and the presence of large amounts of impurities can interfere with the analysis of GMP. More efficient and highly specific GMP purification methods need to be developed. In this review, we have highlighted and summarized the current research progress on the major biological features and purification methodologies associated with GMP, as well as providing an extensive overview of the recent developments in using charged UF membranes for GMP purification and the influential factors.

AbstractThe nucleus pulposus is in a hypoxic environment in the human body, and when intervertebral disc degeneration (IVDD) occurs, the hypoxic environment is disrupted. Nucleus pulposus cell (NPC) ferroptosis is one of the causes of IVDD. N6‐methyladenosine (m6A) and its reader protein YTHDF1 regulate cellular activities by affecting RNA metabolism. However, the regulation of ferroptosis in NPCs by m6A‐modified RNAs under hypoxic conditions has not been as well studied. In this study, through in vitro and in vivo experiments, we explored the underlying mechanism of HIF‐1α and YTHDF1 in regulating ferroptosis in NPCs. The results indicated that the overexpression of HIF‐1α or YTHDF1 suppressed NPC ferroptosis; conversely, the knockdown of HIF‐1α or YTHDF1 increased ferroptosis levels in NPCs. Luciferase reporter assays and chromatin immunoprecipitation demonstrated that HIF‐1α regulated YTHDF1 transcription by directly binding to its promoter region. Polysome profiling results showed that YTHDF1 promoted the translation of SLC7A11 and consequently the expression of the anti‐ferroptosis protein GPX4 by binding to m6A‐modified SLC7A11 mRNA. In conclusion, HIF‐1α‐induced YTHDF1 expression reduces NPC ferroptosis and delays IVDD by promoting SLC7A11 translation in a m6A‐dependent manner.

AbstractIntroductionDespite increasing incidence of impacted fetal head at cesarean birth and associated injury, it is unclear which techniques are most effective for prevention and management. A high quality evidence review in accordance with international reporting standards is currently lacking. To address this gap, we aimed to identify, assess, and synthesize studies comparing techniques to prevent or manage impacted fetal head at cesarean birth prior to or at full cervical dilatation.Material and MethodsWe searched MEDLINE, Emcare, Embase and Cochrane databases up to 1 January 2023 (PROSPERO: CRD420212750016). Included were randomized controlled trials (any size) and non‐randomized comparative studies (n ≥ 30 in each arm) comparing techniques or adjunctive measures to prevent or manage impacted fetal head at cesarean birth. Following screening and data extraction, we assessed risk of bias for individual studies using RoB2 and ROBINS‐I, and certainty of evidence using GRADE. We synthesized data using meta‐analysis where appropriate, including sensitivity analyses excluding data published in potential predatory journals or at risk of retraction.ResultsWe identified 24 eligible studies (11 randomized and 13 non‐randomized) including 3558 women, that compared vaginal disimpaction, reverse breech extraction, the Patwardhan method and/or the Fetal Pillow®. GRADE certainty of evidence was low or very low for all 96 outcomes across seven reported comparisons. Pooled analysis mostly showed no or equivocal differences in outcomes across comparisons of techniques. Although some maternal outcomes suggested differences between techniques (eg risk ratio of 3.41 [95% CI: 2.50–4.66] for uterine incision extension with vaginal disimpaction vs. reverse breech extraction), these were based on unreliable pooled estimates given very low GRADE certainty and, in some cases, additional risk of bias introduced by data published in potential predatory journals or at risk of retraction.ConclusionsThe current weaknesses in the evidence base mean that no firm recommendations can be made about the superiority of any one impacted fetal head technique over another, indicating that high quality training is needed across the range of techniques. Future studies to improve the evidence base are urgently required, using a standard definition of impacted fetal head, agreed maternal and neonatal outcome sets for impacted fetal head, and internationally recommended reporting standards.

AbstractThe purpose of this study was to investigate the time‐dependent change in Reishi (Ganoderma lingzhi) triterpenoids in rumen fluid. G. lingzhi fruiting bodies were milled and incubated in a tube with rumen fluid for 0, 4, 8, 12, 24, and 48 h at 39°C. After incubation, all the tubes were freeze‐dried and extracted by ethanol. The contents of 18 triterpenoids in the ethanol extract were quantitated by liquid chromatography‐mass spectrometry (LC‐MS/MS). Based on the results, triterpenoids were categorized into three groups: (1) rapid decrease, indicating reductions of more than 50% within 8 h; (2) mild decrease, with reductions of more than 50% within 48 h; and (3) minimal change, even after 48 h, there was not much change. Ganoderic acid C6, DM, H, K, and TR as well as Ganoderenic acid D were classified in (1); Ganoderic acid LM2 and T‐Q as well as Ganoderiol F in (2); and Ganoderic acid A, B, C1, C2, I, and TN; Gnoderenic acid C; and Ganodermanontriol in (3). In addition, a relationship between chemical structure and metabolic speed was observed in some cases. The results of this study revealed that G. lingzhi triterpenoids are digested and metabolized at different speeds in ruminant fluid.
Care or sabotage? A reflexive thematic analysis of perceived partner support throughout the bariatric surgery journey
Authors: Quirke‐McFarlane Sophia , Ogden Jane 
Published: May 2024

AbstractObjectiveSocial support is mostly seen as a positive resource for many health outcomes. However, some research indicates that weight loss may disrupt the equilibrium of relationships and highlights the potential for a more negative form of social support. This qualitative study aimed to explore bariatric surgery (BS) patients' perceptions of the way in which their current or previous partner supported them throughout their BS journey.DesignBS patients (N = 30) participated in semi‐structured interviews.MethodsThe data were analysed using an inductive approach to reflexive thematic analysis.ResultsFour themes were derived from the data. While two themes reflected social support as a form of caring (Mutual Investment and Positive Reinforcements), the other two themes indicated aspects of sabotage (Feeder Behaviours and Negative Reactions to Weight Loss Attempts and Successes). Transcending these themes was the notion of Bariatric Surgery as an Opportunity or Threat to the Relationship.ConclusionsSome patients perceived social support as a positive resource in BS success involving Mutual Investment from their partners and being offered Positive Reinforcements for changes in their weight status and wellbeing. Some, however, described more negative aspects of support which had undermined their BS goals, either unintentionally or intentionally, through acts of sabotage including Feeder Behaviours and Negative Reactions to Weight Loss Attempts and Successes. Future research should develop interventions to help prepare the partners of those undergoing BS for the changes to both their partner's weight status and the dynamics of their relationship.

ObjectiveTo compare the effectiveness of low intra‐abdominal pressure (IAP) facilitated by deep neuromuscular block (NMB) to standard practice in improving the quality of recovery, preserving immune function, and enhancing parietal perfusion during robot‐assisted radical prostatectomy (RARP).Patients and MethodsIn this blinded, randomised controlled trial, 96 patients were randomised to the experimental group with low IAP (8 mmHg) facilitated by deep NMB (post‐tetanic count 1–2) or the control group with standard IAP (14 mmHg) and moderate NMB (train‐of‐four 1–2). Recovery was measured using the 40‐item Quality of Recovery questionnaire and 36‐item Short‐Form Health survey. Immune function was evaluated by plasma damage‐associated molecular patterns, cytokines, and ex vivo lipopolysaccharide‐stimulated cytokine production. Parietal peritoneum perfusion was measured by analysing the recordings of indocyanine‐green injection.ResultsQuality of recovery was not superior in the experimental group (n = 46) compared to the control group (n = 50). All clinical outcomes, including pain scores, postoperative nausea and vomiting, and hospital stay were similar. There were no significant differences in postoperative plasma concentrations of damage‐associated molecular patterns, cytokines, and ex vivo cytokine production capacity. The use of low IAP resulted in better parietal peritoneum perfusion.ConclusionDespite better perfusion of the parietal peritoneum, low IAP facilitated by deep NMB did not improve the quality of recovery or preserve immune function compared to standard practice in patients undergoing RARP.
