Integrated maintenance, inventory and quality engineering decisions for multi-product systems
Authors: Salmasnia Ali , Hafezian Rahil , Maleki Mohammad Reza 
Published: January 2023

Abstract
It is essential for manufacturers to consider the interrelation among quality, inventory, and maintenance decisions to detect imperfect quality products, keep the production system in good operating condition, and manage quality and inventory costs. Hence, this paper aims to develop an integrated model of inventory planning, quality engineering, and maintenance scheduling in which the expected total cost per time unit is minimised by determining the sample size, sampling interval, control limit coefficient, along with production cycle time. In this regard, an imperfect multi-product manufacturing system is considered, in which the inventory shortage in satisfying the demand for each product type and the idle time during the production cycle are not allowed. It is assumed that the process starts in an in-control condition where most produced units are conforming. However, due to the occurrence of an assignable cause (AC), the process mean moves to an out-of-control condition in which a significant fraction of non-conforming units is produced. The efficiency of the proposed mathematical model is evaluated by a numerical example, and then the sensitivity of the proposed model to important inputs is analysed. Finally, a comparative study based on the Taguchi design approach is given to confirm the capability of the proposed model to achieve remarkable cost savings.
Does Monetary Policy Solely Correct Disequilibrium in the Balance of Payment? Evidence From the Developing World
Authors: Khan Muhammad Azam 
Published: January 2023

Abstract
Monetary policy and balance of payments (BoP) are the key parameters in any country’s economy performance. This study is an attempt to re-explore the impact of domestic credit provided by the financial sector, real interest rate, real GDP growth, inflation rate, and exchange rate on the balance of payments by net foreign assets (NFA) in 17 developing countries over 1982–2019. The most appropriate empirical strategy has been implemented to obtain robust empirical results. The results indicate that domestic credit, interest rate, inflation and exchange rate have a significantly negative, while real GDP growth has a significantly positive impact on NFA. The results of Granger causality test reveals a bidirectional causality between domestic credit and NFA, between exchange rate and NFA. Furthermore, in the case of individual country analysis, overall empirical estimates of three estimators are acceptable for 17 individual countries although some dissimilarities are found between the countries in the magnitude of estimated coefficients of variables and level of significance. Empirical findings suggest that to correct the disequilibrium in BoP, central banks (monetary authorities) need to give equal consideration to other policy measures along with the monetary instruments to accomplish stability in a country’s BoP account.
Resilience and Path Dependency: Income Distribution Effects of GDP in Colombia

Published: January 2023

Abstract
This study examines the effect of GDP per capita on the Gini index, which measures income concentration, in Colombia. The methodology used is an econometric analysis of time series with data extracted from the Inter-American Development Bank and the World Bank. The econometric results suggest that, at least during the period studied here, there is no evidence that GDP per capita has been an explanatory variable of the behaviour of income distribution in Colombia. The results also align with the understanding that the problem of inequality in the distribution of income is not merely economic but concerns persistent matters such as political and historical issues.

Published: January 2023

Abstract
Pineapple is widely grown in tropical countries, and the fruits are well-known for their unique flavor. The ideal stage of maturity, optimum storage temperature, congenial relative humidity, and adequate type of packaging are critical factors that determine the shelf life and quality of pineapple fruits. Therefore, this investigation was carried out to determine the effect of maturity stage and shrink-wrap packaging, along with ambient and low-temperature storage in order to determine the impact of these factors on extending the shelf life and quality of pineapple fruits. The results revealed that fruits with 75% yellow tubercles at the harvesting stored under ambient temperature had a shelf life of just 7 days compared to the fruits having 25% yellow tubercles subjected to shrink-wrap packaging, followed by low-temperature storage, which had a shelf life of 49 days. The findings of this study conclusively proved that harvesting pineapple fruits with 25% of yellow tubercles, followed by shrink-wrap packaging in 25 μ polyolefin film and subsequent storage in a cool chamber at 12–13 °C and 85% relative humidity can prolong the shelf life and will also maintain the quality of pineapple fruits.
Digitalisation and Virtualisation of the Aesthetic Situation Management: Polish Musical Art Creators during the COVID-19 Pandemic
Authors: Szostak Michał 
Published: January 2023

Abstract

Objective: The characteristics of the creative process in musical arts depends on the form in which the aesthetic situation concerning musical arts takes place (traditional in-person or virtual with digital solutions) dangling on the nationality of the musical art creator: Polish versus non-Polish. The following research questions were asked: 1) How do the forced virtualisation and digitisation affect the quality of the creative process within the aesthetic situation between Polish and non-Polish musical art creators? 2) Which qualitative parameters of the aesthetic situation are lost and which are gained in connection with the creative process virtualisation in the eyes of Polish and non-Polish musical art creators?

Methodology: Qualitative, in the forms of literature review and interviews.

Findings: The study reveals differences in the traditional and virtual creative process between Polish and non-Polish musical art creators. The general differences are insignificant; however, particular components are concerned with essential discrepancies.

Value Added: A new approach to the creative process in musical arts depending on the traditional and virtualised forms of the aesthetic situation. This study can have practical implications for: 1) musical art creators to form their perception of the creative process; 2) musical art managers to form their perception of the complex nature of the creative process of musical art groups they manage; 3) musical art institution managers to form their perception of the multifaceted nature of the creative process of musical art creators involved in the institutions they manage; 4) sociologists looking for deeper understanding of the creative process in musical arts.

Recommendations: Perspectives of the research can be large-scale research based on the methodology invented for this paper and more focused research investigating art creators from different countries, regions, and cultures, divided by age, gender or the extent of artistic experience.
UE Organizational Identity. From the Motto Veritate Concordia to Neo-bureaucratic Management
Authors: Dziedzic Justyna 
Published: January 2023

Abstract

Objective: The concept of organizational identity appears mainly in the context of a symbolic-interpretive view of an organization’s functioning in its many dimensions. This article aims to analyze to what extent previous knowledge about the existence of an EU organizational identity is a distinct category in the context of neo-bureaucratic management. It seems particularly interesting to draw attention to the identity context in organizations operating under intercultural management conditions. Their character and disposition may be more complex than in the case of homogeneous organizations. For this reason, the European Union is asking itself questions about its identity in the context of cultural unification and policy issues, and management solutions related to the institution’s functioning at many levels. Therefore, it seems interesting to draw attention to these issues in light of the different contexts of influence. One is the neo-bureaucratic view of the EU institutions’ governance dimensions, which should be regarded as complex organizational identities. They are subject to the modern influence of management visions and benefit from intercultural management processes’ achievements. The EU’s supranational structure, influenced by bureaucratic organizational arrangements, speaking the language of diplomacy, and setting policy for the Member States, constitute a unique organizational identity globally, which is worth verifying through the prism of neo-bureaucratic influences and cultural conditions of European identity.

Methodology: The article is based on a critical analysis of literature dealing with the sense of European Union organizational identity. Provided a theoretical background on orgzniataional identity in neo-bureaucratic management on a European level.

Findings: In its institutional dimension, the European Union faces the dilemma regarding its own identity due to diplomatic disputes over cultivating indigenous cultures and diversity. It is, therefore, a rare phenomenon on the world stage of supranational institutions. Its procedural nature and purpose are also important to harmonize the Member States’ various policies. It is already possible to outline its unique organizational identity. However, it cannot be transferred to territorial and social land, as Europe cannot be a hybrid of cultures or unify its perspective in the face of historical pasts and ethnic representations.

Value Added: Critical discourse on the theory of bureaucratic management and organizational identity. Presentation of the role of European Union identity in management process and giving the organization common values that solidify its form.

Recommendations: Neo-bureaucratic management is an interesting phenomena to explore in cross-cultural discourses. There are several directions for analysis: forms of modern bureaucracy based on practices drawn from the experience of corporations; abuse of the power of supranational organisations; network management in international organizations.

Published: January 2023

Abstract

Background
Pancreatic islet transplantation via infusion through the portal vein, has become an established clinical treatment for patients with type 1 diabetes. Because the engraftment efficiency is low, new approaches for pancreatic islets implantation are sought. The goal of this study is to explore the possibility that a non-thermal irreversible electroporation (NTIRE) decellularized matrix in the liver could be used as an engraftment site for pancreatic islets.

Materials and methods
Pancreatic islets or saline controls were injected at sites pre-treated with NTIRE in the livers of 7 rats, 16 hours after NTIRE treatment. Seven days after the NTIRE treatment, islet graft function was assessed by detecting insulin and glucagon in the liver with immunohistochemistry.

Results
Pancreatic islets implanted into a NTIRE-treated volume of liver became incorporated into the liver parenchyma and produced insulin and glucagon in 2 of the 7 rat livers. Potential reasons for the failure to observe pancreatic islets in the remaining 5/7 rats may include local inflammatory reaction, graft rejection, low numbers of starting islets, timing of implantation.

Conclusions
This study shows that pancreatic islets can become incorporated and function in an NTIRE-generated extracellular matrix niche, albeit the success rate is low. Advances in the field could be achieved by developing a better understanding of the mechanisms of failure and ways to combat these mechanisms.
Relativity and normativity as a challenge of subject- matter teaching and learning
Authors: Führer Carolin , Tesch Bernd , Balg Dominik , Grewe Bernd 
Published: January 2023

Abstract
In a plural and democratic society teaching challenges not only arise from the conditionality and perspectivity of knowledge, convictions and value systems, but also from a postfactual thinking. Questions of how to deal with one’s own subject-specific norms are sometimes pushed into the background in academic subject didactics. The article shows the potential of interdisciplinary comparison by using the example of classroom communication norms within different disciplines with strong subject cultures. An exchange regarding relativity and normativity could profile the subject-specificity of knowledge and knowledge communication as a necessary orientation against simplification and disambiguation for teachers and students in an uncertain world.

Published: January 2023

Objectives:
Hypertension remains one of the important risk factors for cardiovascular diseases and a major global public health problem. The left ventricular hypertrophy is a recognized complication of systemic hypertension and strongly predicts cardiovascular morbidity and mortality. In Nigeria, few studies have evaluated the accuracy of multiple electrocardiography (ECG) criteria in the diagnosis of the left ventricular hypertrophy among hypertensives. This study sets out to determine ECG criterion or criteria that define most accurately echocardiographic left ventricular hypertrophy (LVH) among patients with hypertension in a tertiary health institution in Nigeria.

Materials and Methods:
One hundred and seventy-eight hypertensives and 89 age- and sex-matched controls were recruited consecutively into the study. All participants including hypertensives and control subjects had echocardiography whereas only hypertensive subjects had both echocardiography and ECG. ECG LVH was determined using various ECG criteria.

Results:
The various ECG criteria for diagnosis of LVH were lower in sensitivities (23.5–38.6%) compared to specificities (64.1–72.9%). The sensitivities and specificities were 28.9% and 64.0%, 38.6% and 72.9%, 23.5% and 64.1%, 34.6% and 69.4%, 34.4% and 68.0%, and 38.6% and 72.9% for Sokolow-Lyon, Cornell voltage, Romhilt-Estes, Cornell duration product, Goldberger, and Massoleini criteria, respectively. The areas under the various receiver operating characteristic (ROC) curves were 0.7010, 0.6040, 0.5960, 0.5950, 0.4790, and 0.4660 for Sokolow-Lyon, Cornell voltage, Massoleini, Romhilt-Estes, Goldberger, and Cornell product duration criteria, respectively.

Conclusion:
Cornell voltage, Sokolow-Lyon, and Massoleini ECG criteria had the highest combination of sensitivities and specificities with the highest ROC values and thus most accurate ECG LVH criteria

The unique property combination of Al/SiCp based composites make them very attractive for applications in automotive and aerospace industries. The choice of composite materials for these applications is directly influenced by their inherent properties which are a function of the processing route employed. Like other processing parameters, surface modification treatment of SiCp can play a major role in determining the properties of Al/SiCp composites. In this study, the effects of SiC reinforcement (wt%) fractions (SRF), surface oxidation temperature (SOT) and preheating temperature (PT) parameters on the wear and friction properties of stir-cast Al-SiCp based composite were investigated. Experimental data and models are generated and analyzed based on a three-factors-five-level central composite design (CCD) and analysis of variance (ANOVA). The empirical models developed for wear rate and coefficient of friction (COF) considering the pre-processing parameters adequately predicts the Al-SiCp properties with the silicon carbide reinforcement (wt%) fraction emerged as the most influencing factor. The goal of the optimization process is to minimize both wear rate and COF. For wear rate, SRF at 44.49 % contribution had the most influence on wear rate, while SOT and PT had 0.65 % and 1.03 % influence on wear rate respectively. For COF, SRF also showed highest influence of 35.48 % on COF, while SOT and PT had 0.047% and 2.66% influence on COF respectively. From the optimization analysis, the set of conditions that simultaneously optimizes both wear rate and COF are 10% SiC weight (SW), 1234°C surface oxidation temperature (SOT), and 376.2°C preheat temperature (PT). The resulting responses at this optimized condition are minimum wear rate of 0.11 mm3/m and COF of 0.11 with a confidence and desirability level of 1.

Published: January 2023

In aviation history, accidents during landing are more frequent compared to other phases of flight and in most cases the aircraft is forced to make an emergency belly landing when landing gear malfunctions. This study aims to analyse the energy absorption of a typical composite aircraft fuselage section under such crash belly landing. A finite element model of this composite fuselage section was created and analyzed using LS-Dyna finite element software and the effects of different composite materials on the energy absorption of fuselage section were studied. Four different composite materials that are commonly used in aerospace application were selected for the purpose of the present study namely glass/epoxy, graphite/epoxy, Kevlar/epoxy, and boron/epoxy. An impact velocity of 7 m/s against rigid ground was considered. Results showed that frames and skin contribute the most in energy absorption while the passenger floor and strut contribute the least. Moreover, it was found that fuselage skin made of glass/epoxy absorbed more energy compared to other materials and it had the highest specific energy absorption.
