Published: July 2023

Background – Because of the Covid-19 pandemic, human travel was severely restricted and reliant on digital technology. Tourism is one of the businesses that has been obliged to adapt to digitalization in order to keep its primary source of income from travelers. The present transition to digital tourism is taking the shape of virtual tours or long-distance interactive tours, such as those seen in museums. To reach more tourists, some museums in Indonesia already entered the digitization stage by offering virtual tours and edutainment.

Aim – This study intends to provide emphasis on the advantages and disadvantages of disruptive innovation in the sense of digitization in the tourism industry, particularly museums.

Design / Methodology / Approach – An detailed review of existing literature regarding digital technology, disruptive digital innovation, smartphone technology, social media, internet, and mobile applications from the perspective of museum tourism was used.

Findings – Digital museums provide a new perspective to enjoy their collections and as a diversification strategy that has the potential to bring in tourists virtually. Curators should develop websites using communication strategies that relate to their collection and focus on their visitor profile. On the other hand, there is a risk that there is a conservative opinion that digitization will reduce the integrity of physical artwork and an unstable digital ecosystem.

Conclusion - The digitization and publication of collections online has the potential to enable access to content. It is projected that disruptive innovation in the form of changing the museum's business model will provide financial benefits and become a business diversification that can support the sustainability of the museum itself in the future.

Research implication – In the field of management, disruptive innovation in the form of changing the museum's business model will provide financial benefits and become a business diversification that can support the sustainability of the museum itself in the future. In the field of architecture, the preservation of cultural heritage objects through digitization guarantees digital archives and provides wider educational opportunities virtually.

Research Limitations – The breadth of coverage regarding the digitization of museums and also the many things that still need to be done in order to implement it perfectly, makes research on digitization will continue to be needed. Future studies can complement and continue to update research results so that museums can also continue to evolve.

Owing to the high temperature stability of hysteretic characteristics and corrosion resistance under external actions, (Sm,Zr)(Co,Cu,Fe)z-based magnets are widely used in devices operating at high temperatures, most critical constructions of aerospace engineering and defense technology, and in traction electric motors for transport engineering. A number of modern research methods are used to study in detail the structure and phase composition of the (Sm,Zr)(Co,Cu,Fe)z alloys with z = 5.5 – 7.0 in as-cast state and after heat treatment, which includes the solid solution treatment at 1150 – 1180 °С for 5 h, subsequent water quenching, isothermal aging at 800 °С for 20 h, and cooling (stepped aging) from 800 to 400 °С at an average cooling rate of 100 °С/h. The results obtained allowed us to suggest the schematic diagram of grain-boundary constituent transformation at different stages of heat treatment of (Sm,Zr)(Co,Cu,Fe)z permanent magnets prepared by powder metallurgy. The formation mechanism of high-coercivity state of (Sm,Zr)(Co,Cu,Fe)z permanent magnets in the course of complete heat treatment cycle is given as the sequence of phase transformations accompanied by redistribution of a number of alloy components.

The possibilities of modification of the structure and type of conductivity of WSe2 films formed on p-type silicon by thermal treatment of a thin-film precursor, which was preliminarily created by pulsed laser deposition, are studied. Pulsed laser ablation of WSe2 and rhenium targets made it possible to obtain amorphous films WSex (x > 2) containing rhenium atoms and inclusions of β-W nanoparticles. Heat treatment at 450 °C caused the crystallization of the amorphous matrix and the formation of a layered 2H-WSe2 shell surrounded the metal nanoparticles. Doping with rhenium led to the production of n-type WSe2 semiconductor films, which, in terms of their properties (band gap ~ 1.2 eV, high catalytic activity, low resistance to current transport), represent a promising material for creating p-Si photocathodes for efficient light-activated hydrogen evolution in acid solution. Theoretical calculations are carried out, which make it possible to identify local areas on the surface of the formed WSe2 films with enhanced catalytic activity in hydrogen evolution reaction.

The results of a corrosion-electrochemical study of the effect of lanthanum additives as an alloying component on the anodic behavior of lead babbit of the BLa brand (PbSb15Sn10), in a NaCl electrolyte medium with a concentration of 0.03; 0.3 and 3.0 % (by weight) are presented. The anodic behavior of babbits was investigated by the potentiostatic method at a potential sweep rate of 2 mV/s. The lanthanum content in lead babbit BLa (PbSb15Sn10) was 0.01, 0.1, 0.50 and 1.0 % (by weight). It was found that with an increase in the concentration of chloride ion in the NaCl electrolyte, there is a shift in the negative region of the values of the potentials of corrosion, pitting formation and repassivation of babbits. The free corrosion potential of lead babbit shifts from time to time to the positive region. Regardless of the composition of babbits, an increase in the rate of their corrosion was established with an increase in the concentration of NaCl in the electrolyte. The addition of lanthanum to lead babbit increases its corrosion resistance. It is shown that lead babbit corrodes by the pitting mechanism and lanthanum as an alloying component of lead babbit BLa (PbSb15Sn10) contributes to the shift of the potentials of pitting formation and repassivation to the region of positive values. This leads to an increase in the resistance of lead babbit to pitting corrosion, and also contributes to the healing of incipient pitting foci.
Porosity of nickel nanopowder compacts consolidated by gas extrusion
Authors:   Merzhanov institute of structural macrokinetics and materials science Russian academy of sciences, Alymov M. I.
Published: July 2023

The method of hot gas extrusion differs from other methods of metal pressure treatment in that the processed material is subjected to intense plastic deformation by extrusion under conditions of high isostatic pressure of inert gas and heating in the area of plastic deformation. The method makes it possible to process powder materials, while inevitably there is a need to control mechanical properties by controlling porosity and pressure inside the pores. The paper presents a method for calculating the pressure inside the pores from the minimum size of the closed pore. The pore pressure was evaluated on materials obtained by the consolidation of nickel nanopowders by hot gas extrusion. Quantitative processing of the material cross-section view images obtained by scanning electron microscopy showed that the minimum pore size is 220 nm. The formula for calculating the pore pressure is derived from the formula for calculating the critical pore radius. It takes into account the external impact pressure (the gas pressure during the extrusion process was equal to 400 MPa), the surface tension coefficient and the yield strength of nickel (at the extrusion start temperature of 910 °С), as well as the minimum pore radius. The proposed method for calculating the pressure inside a closed pore will allow us to evaluate the mechanical properties of materials obtained by various methods of powder metallurgy.

Published: July 2023

The evolution of macro- and mesoporous layers of porous silicon formed by Pd-assisted etching with different duration of formation and temperature of the etching solution from 25 to 75 °С, which have the property of ethanol electrooxidation, has been studied. High values of the dissolution rate of porous silicon at a temperature of 75 °С are shown, leading to a significant loss of thickness and specific surface area of the macro- and mesoporous layer, respectively. The obtained porous layers with different surface energy and surface area, show different rates of ethanol dehydrogenation and the number of dehydrogenated ethanol molecules, which allows you to control the activity of the electrode material for ethanol fuel cells.

Up to now Co – Mg alloys have not been studied in detail. The information available in the literature refers to the study of changes in the Co – Mg system in the composition-temperature coordinates. However, this does not take into account the significant difference in vapor pressure values of Mg and Co in the alloy, which significantly reduces the accuracy of the results obtained. It is proposed to analyze the Co – Mg system in the coordinates composition-temperature-pressure. The following results have been obtained and presented in the article: a detailed description of the Mg – Co system diagram in the pressure-temperature coordinates, the projections of the three-phase equilibrium lines, some isobaric and isothermal sections of the p – T – X state diagram of Mg – Co system, Mg – Co state diagram in coordinates temperature – partial pressure Mg. The results obtained in this work can be successfully used in the development of ternary and more alloys containing cobalt and magnesium.

The compressibility of composite materials obtained by impregnation with water dispersion of polyurethane of webs made of polyethylene terephthalate fibers with a diameter of 20 µm and a mixture of these fibers with polyethylene terephthalate fibers with a diameter of 42 µm is investigated. The influence of the composition on the formation of the structure of canvases and composite materials based on them is shown. In the process of heat treatment, the volume of webs made of fibers with a diameter of 20 µm increases and decreases for webs based on a mixture of fibers of different diameters. Compared with canvases, with a degree of impregnation less than 1.0, the water permeability of materials of various compositions increases by 1.5 – 2.0 times. A model is proposed to predict the degree of compressibility of composite materials from the degree of impregnation and load. It is established that compressibility of composite materials decreases when using a web as a fibrous filler in which the fibers are oriented perpendicular to the surface of the web. Less effective for reducing compressibility is the use of a web made of a mixture of fibers of different diameters as a fibrous filler.

In the work, experiments were carried out on the production and testing of hard alloys from powders of the VK10KHOM and VRK15 grades coated with multigraphene obtained by the electrochemical method. Samples with multigraphene were sintered under standard conditions for grades VK10KHOM and VRK15. In the weight ratio, the amount of multigraphene was 0.1 wt. % for the VK10KHOM grade alloy and 0.1 wt. % and 0.5 wt. % for the VRK15 grade. Friction tests of VK10KhOM samples showed that the width of the wear areas of samples with multigraphene is 8 % less than in the original ones. At 0.1 wt. % graphene, the density of the VK10KHOM grade is 14.5 and VRK15 is 14.0, and the porosity is 0.02 % and 2 %, respectively. Comparative tests were carried out on cutting titanium grade VT-3. As a result of cutting, it was found that the coating of powders with multigraphene increases the resistance of carbide inserts of both grades. It is shown that for VRK15 the plate durability increased by 4 times, and for the VK10KHOM grade it was not possible to establish the plate failure time. The increase in wear resistance is presumably caused by a decrease in the coefficient of friction due to multigraphene, which, dissolving in the hard alloy, precipitates in the form of nanographite clusters.

Literary Tourism: Maintaining Balinese Identity in 'Host-Guest' Interaction in Short Stories by Balinese Writers
Authors: I Nyoman Darma Putra  , Ida Bagus Jelantik Sutanegara Pidada
Published: July 2023

The development of tourism in Bali with strong socio-cultural influences has inspired Balinese writers to create literary works about the interaction between Balinese people  (hosts) and tourists (guests), both in Indonesian and Balinese language. This study examines how Balinese authors maintain Balinese identity in host-guest interactions  featured in short stories by Balinese writers. The main object of research is the anthology of Balinese short stories Mekel Paris (Madame Paris, 2012) by IBW Keniten because all short stories in this anthology contain stories of interactions between Balinese and foreigners. Data from the short stories and interviews with authors were analyzed qualitatively using a tourism literary approach, an approach that uses anthropological tourism theory of host-guest contact  introduced by Valene Smith. The results showed that there are various forms of host-guest interaction expressed in the Mekel Paris anthology, namely harmonious, conflict, mutualistic, and transactional interactions. Although there are various forms of interaction, all of them have one goal, which is to convey the message so that the Balinese people are not carried away by foreign influences, but are firm in maintaining Balinese identity. In addition to enriching the discussion on how Balinese people maintain their identity, this article also contributes to the development of the study of tourism literature that is growing rapidly in Indonesia.

Gender differences, in social studies and science achievement, in a technology-enhanced learning environment were examined from a group of 474 (males=237 and females=237) first-time 8th grade test takers from one primary school district. Unequal variance independent samples t-tests were used to test the magnitude of gender differences. Female students received significantly greater social studies achievement than males, but there were not significant differences in science achievement scores. Achievement assessments for students with assigned laptops showed significant gender differences in social studies, but not in science. 
The Obama Administration and Egypt’s Muslim Brotherhood (2010-2016): Ally or Predicament?
Authors: Aty Mourad
Published: July 2023

The Muslim Brotherhood has always been very controversial. Since its creation in the late 1920s, it has been at the heart of Egypt’s most important upheavals and struggles. As a Pan-Islamist religious and social movement, its self-stated aim is “Islam is the solution”. During the early days of the so-called “Arab Spring,” the movement was the readiest political power to go through the electoral process and achieve victory far more than any other party. This was due to its long history in charity and social services and the well-organized preachers who are deeply rooted in Egyptian society. The sharp victory in the 2011 Legislative Elections was not enough for the movement. Backed by his Islamist allies and most of the youth who participated in the “Revolution,” Mohamed Morsi ran for president and won in 2012. One year later, he was ousted after a “second uprising” in the streets of Cairo and many other Egyptian cities. Another crackdown was inevitable and the movement went back to clandestinity. Amidst all these events, the United States under President Obama could not distance itself from what was going on. In the beginning, the US administration was divided over the popular uprisings in the whole region and in Egypt in particular. In Egypt, the Obama administration backed Morsi during his presidency although his movement was known to be traditionally against Western interests in the region. Many Egyptian politicians were into the idea that the cabinet was compromised and officials with connections to the Muslim Brotherhood were influencing the decision-making process. When it was time, the US government has leaned into the army which is the only institution that guarantees the peace treaty with Israel. The aim of this paper is to provide an understanding to the blur in the US stance before and during the period when the army took over. It explains the major interests which did not make the issue of democracy a priority and led to the disposal from the Muslim Brotherhood.
From Warlords to Politicians: Transforming Rebel Movements Into Political Parties

Over the past few decades, African countries have faced a new phenomenon in political life – the ascent to power of former warlords – leaders of insurgent anti-government movements or tribal militias, who become presidents, vice presidents, prime ministers and members of parliament. Warlords seek to translate their wartime gains into material wealth and social status and gain political office to consolidate their military exploits. To achieve this, they employ many different strategies: transforming their armed groups into political parties, joining existing political organizations, establishing totally new parties, or conducting individual political activity. In societies where power is accumulated through the expansion of social networks – political, economic, military, ethnic, religious, regional, etc. – it becomes extremely useful for a politician to play several leadership roles. Access to various networks allows leaders to expand their base of support: this partly explains why African political elites are represented not only by politicians, but also by businessmen, priests, football players and former warlords. Since most African countries since independence have been in a constant transition from authoritarian to “democratic” governance, from public sector dominance to liberal economies, from limited violence to large-scale warfare, elites have constantly had to invent new roles for themselves in order to maintain political power. If they were unable to achieve the transformation that the situation required, they risked becoming marginalized figures. In this sense, recent warlords intuitively felt it inadvisable to distance themselves from their past wartime activities. Depending on the audience and circumstances, they either emphasized their former merits as field commanders, or, on the contrary, diligently portrayed themselves as vigorous peacemakers. The literature on peacebuilding and post-war reconstruction, with rare exceptions, ignores such an important aspect as the influence of former warlords on post-conflict electoral processes, focusing almost exclusively on organizational issues, the level of effectiveness of state institutions, intra- and inter-party struggles, methods of ensuring security, and the degree of readiness of polling stations. The present paper aims at filling this gap.
The Need for Ideological-Based Political Parties in Sub-Saharan Africa. Case Study the MPLA and UNITA of Angola
Authors: Agostinho Issau
Published: July 2023

The political movements in Africa have gone through a significant transformation throughout decades. When the first movements started in the Sub-Saharan region in earlier decades of the 20th century, they would just act as cultural or social associations, since the colonial order would not allow national political movements to exist in African societies under their rule. But during the 1950-1960s those associations transformed into political movements and parties that ultimately fought for independence and transitional governments, respectively. However, 60 years after the national liberations, most African ruling parties, especially the historic ones, are very much keen to explore identity differences from one another to hold onto power, despite the multiparty democratic regimes in which they operate. The claim to belonging to a certain identity (which may be even religious or linguistic) has degenerated into violence and civil wars in many post-independence African societies (Central African Republic, Cameroon, Angola, Mozambique, Kenya, just to mention a few). The assumption that identity-based political parties have not worked well for stronger, peaceful, and integrated African societies (except for a few countries) should bring about a new format of political parties that are ideological-based and which, despite all cultural differences, can indeed offer a better social-political confrontation among different political parties based on a whole set of ideological values. So, although a post-or-quasi-ideology permeates most historical political parties across Sub-Saharan Africa, this paper focuses primarily on the MPLA and UNITA post-war political ideologies as it looks at ideological patterns and verifies through their Statutes the existence of a quasi or full-scale political ideology, and how both parties relate and operate within the framework of political discourse in today’s Angola.

Loyal to a fault: Mistaken reputational pressures fuel partisan endorsement of winning at all costs
Authors: Dorison Charles , Kteily Nour
Published: July 2023

In the polarized context of American politics, we study a phenomenon we term winning at all costs: prioritizing ingroup political gain at the expense of immediate societal harm. Do individuals believe the outgroup is willing to win at all costs, and does this impact hostility? Do individuals also think their ingroup is willing to defeat the outgroup at all costs? How well-calibrated are these beliefs, and how do (mis-)perceived reputational pressures shape individuals’ own behavior? Five pre-registered studies (N=6,408) address these questions. Individuals overestimated both outgroup and ingroup willingness to accept societal harm for political gain. (Over)Perceiving outgroup willingness to win at all costs uniquely predicted outgroup animus. And individuals’ mistaken assumptions about reputational rewards from their ingroup increased their endorsement of winning at all costs when their decisions were observable. Our work reveals how an underappreciation for the limits of both ingroup and outgroup partisan psychology reinforces intergroup conflict.
Reciprocal contracts—not competitive acquisition—explain the moral psychology of ownership

Published: July 2023

We applaud Boyer's attempt to ground the psychology of ownership partly in a cooperative logic. In this commentary, we propose to go further and ground the psychology of ownership solely in a cooperative logic. The predictions of bargaining theory, we argue, completely contradict the actual features of ownership intuitions. Ownership is only about the calculation of mutually beneficial, reciprocal contracts.

Background: While irritability is one of the most common problems for which families seek mental health treatment for children, it is still unclear how factors such as age, sex, and reporting source influence the prevalence of and impairment due to irritability in youth in the population. Methods: Using data from Mental Health of Children and Young People Survey 2017 in England we examined the prevalence of irritable mood and temper outbursts in 6,881 children aged 5-17 using parent report (49.8% females) and in 2,904 children aged 11-17 for self-report (50.7% females). Informaiton on irritability was collected with the disruptive mood dysregulation disorder (DMDD) section of the Development and Well-Being Assessment (DAWBA). We also examined associations with mental health difficulties and impairment (SDQ) as well as psychiatric disorders (DAWBA). Results: Parents reported higher levels of irritability in males (20-25%) compared to females during childhood (15-19%), but this difference disappeared in adolescence. On the other hand, adolescent females reported more irritable mood in themselves (29%) compared to adolescent males (23%). This self-reported irritability in adolescent females was associated with greater emotional problems (b=0.28, SE=0.10, p=0.004) and overall impairment (irritable mood, b=0.29, SE=0.09, p=0.001; temper outbursts: b=0.28, SE=0.08, p<0.001) compared to males. The presence of irritability in females was also associated with a higher relative increase of psychiatric disorders, particularly those of externalizing nature (b=0.53, SE=0.15, p=0.001)Conclusions: Age, sex, informant, and their interactions are sources of heterogeneity in irritability reporting. These results highlight the importance of considering the perspectives of adolescents, and females sin particular, when assessing irritability in young people, since we might otherwise miss information on experiences of affect that might not be observable by external informants. Future studies should clarify whether gender biases exist in parent-reported irritability and its correlates.
