Urban Image Communication Strategy under the New Media Environment
Authors: Yuan Quan
Published: May 2023

The promotion of city visibility cannot be separated from the spread and shaping of city image. The rapid development of the Internet provides new means and ideas for the spread of many city images. In recent years, in order to promote the development of tourism and shape the city image, the city has adopted various strategies. The main approach is to publicize various regional characteristics of the city through the Internet new media technology, so as to build an Internet celebrity city. Cities such as Xi 'an, Chengdu and Changsha have been transformed into "Internet celebrity cities", becoming hot cities on the Internet and the places where people want to hit the time card, gaining extremely high visibility and thus enhancing the soft power of cities. Of course, while new media bring popularity to cities, they also face many new problems. This paper mainly takes Changsha's successful shaping of city image in the context of new media as an example, analyzes the existing problems of Changsha's city image construction and communication, and puts forward some strategies.

From the Perspective of the Labor Market, The Opportunities and Challenges Brought by the New Generation of Artificial Intelligence Technologies such as ChatGPT are Analyzed
Authors: Liu Jun
Published: May 2023

The emergence of artificial intelligence has changed the way people live and work, with the update and iteration of technology, artificial intelligence is widely used in many fields, and at the same time, the labor market in the era of artificial intelligence is also a relatively differentiated market. In this context, the application of a new generation of artificial intelligence technology has affected the labor market, on the one hand, a large number of repetitive jobs in the next few years may be replaced by automation technology with higher productivity, efficiency and lower error rate, which means that a huge number of low-skilled workers face the problem of "machine substitution" unemployment; On the other hand, with the upgrading of technology, new jobs are created, and there is a large demand for labor with new skills, new experience and new knowledge, especially high-skilled, high-knowledge, and highly specialized labor with creativity and innovation ability. This paper argues from many aspects that the two-way impact of artificial intelligence technology on the labor market is far more beneficial than harmful, and we must pay attention to the impact of the vigorous development of artificial intelligence on the labor market. In the next decade, the impact of artificial intelligence on the labor market will become increasingly prominent, and it is necessary to pay close attention to technological changes, formalize the opportunities and challenges brought by the new generation of artificial intelligence technology to the labor market, and keep pace with the times to adapt to future labor market changes.

Statistical theory of individual activity coefficients of electrolytes including multiple ionic charges
Authors: Ebeling W. , Krienke H.
Published: May 2023

In previous work we developed a new statistical method for calculating the individual activities of ions including the association of ions. Here we study multi-particle electrostatic interactions connected within higher cluster integrals and identify the ionization constants of the mass action law of associating ion clusters. In contrast to Bjerrum and Fuoss, our concept of association is not based on spatial criteria, but instead on the strength of interaction measured in powers of the Bjerrum parameter (e2/D0kBTa; a is contact) and defined by asymptotic properties of the cluster integrals. For ion pair formation our mass action constant is the classical counterpart of Planck's famous hydrogenic partition function. As a rule, the new association constants are smaller than traditional expressions, e.g., by Fuoss and Kraus, in the interesting regions of interaction parameters about fifty percent. Several examples including CaCl2, MgCl2, Na2SO4, K2SO4, LaCl3 and a model of seawater are studied. For several associating electrolytes and seawater, reasonable agreement with experiments and Monte Carlo results is achieved.

Published: May 2023

A quantum theory of spectral parameters and oscillator strengths of quantum transitions in an active region, which contains cascades of wide quantum wells with a complicated potential profile is developed. A new spatial design of the cascade is calculated and proposed with such an asymmetric arrangement of the wells and barriers, in which, without an applied electric bias, the magnitudes of oscillator strengths are considerable and one-way resonant-tunneling transport of electrons is observed. As a result, it becomes possible to ensure a successful functioning of the broadband photodetector in the far IR range.

Published: May 2023

We study the electronic and magnetic properties of T2AlC (T = Ti and Cr) compounds in the density-functional theory using the generalized gradient approximation (GGA) with consideration of strong Coulomb correlations (GGA+U) in the framework of the fully relativistic spin-polarized Dirac linear muffin-tin orbital (LMTO) band-structure method. The X-ray absorption spectra and X-ray magnetic circular dichroism (XMCD) at the Cr L2,3 and Cr, Ti, and C K edges were investigated theoretically. The calculated results are in good agreement with experimental data. The effect of the electric quadrupole E2 and magnetic dipole M1 transitions at the Cr K edge has been investigated.

Authors: Arbaeen Ahmad
Published: May 2023

Objectives: According to studies in different countries, burnout is one of the mental health issues afflicting students in high school and college,. While burnout is prevalent among all students, however, medical students are more prone due to the higher stressors compared to other university departments. This study was conducted to investigate the burnout prevalence and their associated factors using the Maslach Burnout Inventory – General Survey (MBI-GS) among students pursuing first year (preparatory year) programs across various health colleges at Umm al Qura University in Makkah. In the study, we attempted to correlate health habits such as smoking, consumption of energy drinks, and obesity with burnout prevalence among students in health colleges. Methods: A cross-sectional survey was used to assess the prevalence of burnout in this student population to assess the three subscales of (MBI-GS): emotional exhaustion, cynicism, and professional efficacy. Results: From the 895 students participated in the study, 39% were male and 61% were females. We found a significant difference (P<0.05) between male and female groups in the exhaustion and cynicism subscales, whereas the professional efficacy sub-scale did not show any significant difference. Concerning the exhaustion subscale, female students displayed higher high burnout level than male students (38.1% vs 20.4%) while males showed higher moderate and low percentages than females. The cynicism subscale showed higher high and moderate burnout levels in females than males, while low burnout level was higher in males than females. Exhaustion subscale showed significant negative correlations with nationality (male: r = -0.126, P = 0.019), supplementation usage (female: r = -0.102, P = 0.017), and energy drinks intake (female: r = -0.086, P = 0.045), while positive correlations with BMI (female: r = 0.087, P = 0.042), and marital status (male: r = 0.126, P = 0.018). Conclusion: We can conclude that burnout is indeed prevalent among medical university students. Among female student, we found out that the higher the body mass, the greater the burnout rate. Furthermore a positive correlation between, lower income higher apathy and the loss of personality, among students. Despite the proven harm from the increased consumption of energy drinks, the increased consumption of stimulants and energy drinks reduced burnout and raised attention.

Objectives: The current study was designed to capture comprehensive imaging of acute ischemic stroke (AIS) using multidetector computed tomography (MDCT). The study also evaluated the accessibility and potential use of computed tomography angiography (CTA) and sought to determine stroke subtypes in patients with AIS. Methods: The presence of ischemic lesions was detected by the MDCT, transesophageal echocardiography (TEE), and non-contrast flat detector computed tomography (FDCT). The study selected the AIS patients with hyperacute stroke for less than 6 hours from July 2021 to August 2022. The CTA of cervical arteries was performed in order to determine stroke subtypes. Results: The MDCT-based detection of ischemic lesions in 110 studied ischemic stroke patients showed 34% had extensive intracranial artery damage, 86% detected a partial territorial infarct, while 52% patients had detected artery-to-artery embolization. These percentages of detected ischemic lesions overlapped in all studied AIS patients. The findings showed significant susceptible plaques and arterial stenosis. Conclusion: The findings of the study clearly indicated that AIS patients admitted within less than 6 hours of a hyperacute stroke showed multiple types of ischemic lesions. The findings also concluded that the MDCT technique is highly useful for the detection of multiple patterns of brain infarction and for the determination of the causative mechanisms in patients with acute ischemic stroke.

Published: May 2023

Purpose: To explore the effect of market penetration strategies on the market performance of small and medium-tiered deposit-taking SACCOs in Kenya

Methodology: This proposed study utilized the positivist research philosophy and adopted a descriptive research design. A census of all 141 small and medium deposit-taking-SACCOS was conducted. Data was collected using questionnaires which were physically or electronically administered to the CEOs or their assistants who were the respondents in this study. Data analysis utilized descriptive and inferential statistics which were used to deduce the nature and strength of the relationship between variables. The inferential analysis yielded correlation and regression outputs which are best for determining relationships and prediction among variables. Key correlation and regression analysis techniques such as the coefficient of determination (r2) were utilized. The analysed data was presented using tables, charts and graphs.

Findings: The findings confirmed that market penetration strategies have a positive and significant effect on the market performance of small and medium-tiered deposit-taking SACCOs in Kenya (β=0.490, p=0.000). This implies that changes in 1 unit of the aspects related to market penetration strategies lead to a change in the market performance of small and medium-tiered deposit-taking SACCOs in Kenya by 0.490 units. Hence the rejection of the null hypothesis that market penetration strategies are not statistically significant to the market performance of small and medium-tiered deposit-taking SACCOs in Kenya.

Unique contribution to theory, policy and practice: From study results when market penetration strategies such as service, brand, pricing and promotion differentiation are effectively induced by small and medium-tiered DT-SACCOs, the resultant effect is growth in sales revenue and market share, an increase in the number of new customers growth, service delivery excellence as well as growth in the number of innovations. Furthermore, small and medium DT-SACCOs are better engrained in the market, making them suitable to serve customers’ needs and attain a better position in the market when compared to other competitors. The study thus concluded that relationship between market penetration strategies and market performance is statistically significant, however in spite of the effect being statistically significant, study also found out that given a mean score of 3.59 and 3.62 respectively, brand differentiation and service differentiation strategies did not effectively boost market performance. The study thus recommends that small and medium Deposit taking SACCOs should invest in high yielding market penetration strategies such as price differentiation and increased advertising in order to boost market performance.

Authors: Chau Mai Hai , Nhuan Nguyen The
Published: May 2023

Potato (Solanum tuberosum L.) is one of the most valuable crops in the world, ranked as the 4th most important food crops after rice, wheat and maize. Currently, a variety of techniques for producing potato minituber have been investigated, including soilless aeroponic, hydroponic and deep-water culture systems. However, minitubers potato production in the greenhouse from apical rooted cutting grown coco-peat under a photoperiod and nutritional - shock system is a new and creative idea. The use of diazotrophic bacteria such as Azospirillum brasilense demonstrates a positive effect on nitrogen availability, a primordial element for the development of this plant. Therefore, this study aimed to evaluate the growth and minitubers yield in a potato cultivar inoculated with A. brasilense at different doses. The experiments were conducted in controlled greenhouse on concrete raising beds with dimensions of 10 m x 1 m x 0.3 m. The study revealed that the concentration of A. brasilense at different doses significantly affected the height growth, leaves growth, leaves area growth, the average number of tubers plant-1, standard tuber and potato seed minituber yield. The treatment applied with A. brasilense at a concentration of 200 mL m-2 after planting gave the highest yield of potato minitubers (277.8 tubers m-2).

Authors: Bac Bui Van , Doi Bui The
Published: May 2023

The alteration of tropical forest structures due to human activities can have negative impacts on various organism communities. The purpose of this study was to investigate how forest canopy cover affects the species composition and community structure of fruit-feeding butterflies in the karst ecosystems of the Huu Lien special-use forest, Lang Son Province. Three forest fragments with high (>80%), medium (50-80%), and low (<50%) levels of canopy cover were examined. We collected fruit-feeding butterflies using Van Someren-Rydon traps, with 30 traps deployed evenly across the three fragments from May 2022 to March 2023, recording 27 butterfly species of 557 individuals in total. The results indicated that the forest fragment with medium canopy cover had the highest species richness and diversity of fruit-feeding butterfly communities. Although most species were found in all three forest fragments, the Nonmetric Multidimensional Scaling (NMDS) analysis significantly separated the community structures of fruit-feeding butterflies among the three fragments. The two species, Kallima incognita Nakamura & Wakahara and Stichophthalma fruhstorferi Röber, were mainly found in the forest fragment with high canopy cover and were considered as indicator species for this forest type. This study demonstrated the impact of forest canopy cover on the structure of fruit-feeding butterfly communities and emphasized the importance of forest canopy cover in conserving and maintaining insect diversity in karst ecosystems.

Published: May 2023

Organizational culture is one of the resources used by companies to obtain competitive advantage and organizational sustainability, whether by financial, social or environmental efficiency (Chatman & O’Reilly, 2016; Dyck et al., 2019). Another resource that is being encouraged to try and achieve sustainability is Corporate Social Responsibility (CSR), which can be facilitated or inhibited by organizational culture (Leandro & Rebelo, 2011; Shanak et al., 2020). Therefore, this study aims to analyze the relationship of organizational culture and CSR practices on environmental performance in companies listed on [B]³ (Brasil, Bolsa, Balcão), São Paulo’s stock exchange. The results indicated that there are no direct relations between organizational culture, environmental performance and the mediating effect; however, at the significance level of 10%, companies with high polluting potential become more harmful to the environment when there is a predominance of market and hierarchical culture.
Solid-State Characterization of Heteropolyacid-Phyllosilicate Complexes: Structural, Morphological and Thermal Properties
Authors: Vuillaume Pascal Y. , Mokrini Asmae , Robitaille Lucie , Bébin Philippe , Leblond Lori
Published: May 2023

We have previously described the complex formation from a synthetic smectite clay, Sumecton SA (SSA), and the heteropolyacid (HPA), 12-phosphotungstic acid (PTA). Three new synthetic layered aluminosilicate clays of the smectite- [Lucentite SWN (SWN)] and (fluoro)mica-type [Tetrasilicic mica (TSM); Somasif ME100, (SME)] have been self-assembled with PTA, at a specific PTA-clay weight ratio of 5. New protogenic inorganic complexes have been prepared for the future fabrication of proton exchange membrane for fuel cell devices (PEMFC). Complex formation, thermal and structural properties of PTA-phyllosilicate complexes have been investigated using EDX, XRD, SEM, and DRIFT. EDX indicates that complexes incorporate a substantial amount of PTA (50-60% w/w) and that a moderate depletion of Mg2+ ions from octahedral layers of micas clays occurs during the process compared to smectite ones. In contrast, a significant amount of F is removed from the octahedral framework of the mica clays. DRIFT experiments indicate that the Keggin structure is preserved within all complexes and that complex formation predominantly involves the external oxygen (W-Od) of PTA. According to Patterson functions, coherence lengths - which reflect for the virgin clays the extent of the longitudinal platelet stacking (Lc) - of the two smectite clays (Lc ~25 Å) are significantly lower than for their analogous of the mica type (Lc = 180-225 Å). Clays in complexes are characterized by the loss of in-plane organization but are still partially ordered. The nature of the order is still speculative but could be related to the formation of a new inorganic PTA species formed during the complex formation. Compared to the virgin clays, the order of smectite complexes is maintained in the same range (Lc = 27-42 Å) while for mica complexes, coherence lengths are dramatically reduced to ~ 60 Å. All PTA-activated complexes contain a substantial amount of amorphous silica, which tends to increase when heated at temperatures above 280 oC. However, the Keggin structure within the complexes is at least stable up to 280 oC and even, for the most robust TSM complex, up to 450 oC.

Published: May 2023

The quantification of torques and moments of inertia of horizontal axis hydrokinetic turbine driveline is important to precisely predict the dynamic behavior of the complete system. Initially, this paper presents different models used in the literature for describing torques and moments of inertia of turbine components. A dynamic model of a small hydrokinetic turbine using belt transmission is developed. The model uses the Blade Element Momentum (BEM) for determining the power coefficient of the turbine rotor and considers the inertial effects and dissipative torques of whole system using some of the torque models and moments of inertia described previously. The results for the dynamical behavior of the turbine model are compared with experimental data, showing good agreement. In order to numerically analyze a more efficient drivetrain, the belt transmission is replaced by a planetary gearbox in the dynamic model, and the new results are also assessed. As a result, it was found that with planetary gears, a more compact transmission can be used, reducing the inertial effects, which brings a better efficiency in the starting of the machine and shortening the transient regime time.
Determinants of farm investment in Somalia: A var model application
Authors: Nur Abdulkadir Mohamed
Published: May 2023

The main objective of this study is to examine the determinants of farm investment in Somalia using quarterly time-series data from 2015 to 2021. The study selected financing assets (FA), farm output (FO), credit for commercial banks (CCB), and saving (S) as macroeconomic variables. The augmented Dickey–Fuller (ADF) test was employed to evaluate the stationarity of the variables, and the Granger causality test was used to assess the causal relationship between the study variables. It was found that all variables became stationary at the second difference, with a trend for each of the three critical levels of 1%, 5%, and 10%. The Granger causality test indicates a unidirectional causal connection between farm investment, farm output, financial assets for commercial banks, savings for commercial banks, and loans for commercial banks in Somalia. The vector autoregressive (VAR) estimation revealed that the coefficient of determination explains 98% of the model, and the ordinary least squares (OLS) estimation showed a highly significant P-value. The results show that financing assets and savings will increase farm output if managed effectively and efficiently. Based on the findings, the study recommends that the government focus on the overall institutional framework in Somalia to facilitate economic growth, poverty reduction, and sustainable development.
Encryption in India: Preserving the Online Engine of Privacy, Free Expression, Security, and Economic Growth
Authors: Nojeim Greg , Maheshwari Namrata
Published: May 2023

This article argues that the traceability mandate imposed in India by the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021 undermines encryption and negatively impacts cybersecurity as well as the fundamental right to privacy. In doing so, it explains how the traceability requirement fails the necessity and proportionality test laid down by the Indian Supreme Court in the Puttaswamy judgment, wherein it held that the right to privacy is a fundamental right under the Constitution of India. Further, the article makes a case for why encryption is important for protecting privacy, free expression, and other human rights, and also for bulwarking the economy, preserving democracy, and ensuring national security. Part I of the article provides a background on how encryption works and the purpose it serves in the digital era. Part II analyzes the trajectory of encryption policy in India and the relevant legal frameworks. Thereafter, Part III explains the traceability mandate under the New Intermediary Guidelines and its effect on encryption, and consequently, the impact on cybersecurity and the right to privacy. It assesses whether it meets the requirement of necessity and proportionality as set out by the Supreme Court. Finally, Part IV explains that encryption should be protected and encouraged because it guards against unwarranted surveillance and preserves privacy and expression, is a crucial tool to protect human rights in the digital age, strengthens national security, and benefits the economy
The Triumph of Politics: The Republican Party's Takeover of the US Supreme Court
Authors: Rosenberg Gerald N.
Published: May 2023

In this article, Gerald N Rosenberg revisits his 2014 argument that the US Supreme Court is a political institution. Its decisions in affirmative action cases in education are best understood through the political preferences of the justices. Eight years later, the author finds that the Court's opinions have only strengthened this argument. The article analyses affirmative action cases in education between 2014 and mid-2022 and illustrates the power of politics in explaining some of the most important and controversial decisions of the Roberts Court. These include decisions on voting rights (Shelby County v Holder), gun rights (District of Columbia v Heller) and abortion rights (Roe v Wade). The article re-emphasises the need to read these decisions through the political and cultural system within which the Court operates, rather than relying solely on law and precedent.
Building Digital Walls and Making Speech and Internet Freedom (or Chinese Technology) Pay for It

More broadly, the tools at the US government’s disposal— IEEPA, Congressional lawmaking authority, and CFIUS review—encourage the use of such flimsy rationale and a lack of transparency, which ultimately promotes such broad bans; and the costs of these bans are dear. There may be First Amendment implications, and at the very least, a chilling of speech. There are also significant impacts on American foreign policy, from legitimizing the Chinese strategy of cybersovereignty and government regulation, to the creation of incentives to localize data in a manner that might undermine American law enforcement efforts.

– Although the International Court of Justice is the principal judicial organ of the United Nations and is often tasked to resolve inter-state disputes concerning a wide array of subject matter, neither its rules nor jurisprudence readily disclose any consistent or even clear approach on the issue of standard of proof. We make the case that a tiered approach to standard of proof can and should be adopted, and in doing so, identify the various factors that may be relevant in understanding the court’s different positions in different situations.

Chimera has several important definitions that are common to each other, where he is known a single creature that is made up of two or more separate populations of genetically unique cells that originated from various zygotes. Definition can be interpreted as cells from one person might appear in another individual in a process known as chimerism. These cells may be incorporated into the parenchyma or they may circulate. Chimeras are divided into several types depending on several factors such as the percentage of chimera cells in the body of the organism neighborhood, origin, or other reasons, which includes microchimeras, natural human macro-chimeras and man-made chimeras. Chimeric cells in human can arise from three significant sources, namely originating from gestation, blood transfusions, and transplants.

Salah satu masalah sosial terkait lingkungan yang sering ditemui di masyarakat adalah banyaknya timbunan sampah, salah satunya di perkotaan di Indonesia. Hal tersebut ditandai dengan rata-rata sampah yang dibuang sebanyak 0,85 kg setiap hari. Hanya 41% sudah diangkut dan diolah dengan baik. Sisanya sekitar 300.000 ton sampah tidak diangkut dan mencemari lingkungan. Dari permasalahan tersebut maka dirancanglah suatu aplikasi bank sampah berbasis mobile yang dapat meningkatkan kegiatan daur ulang serta mengurangi volume sampah agar mempermudah pengelolaan dan pemanfaatan sampah. Aplikasi ini menyediakan wadah tempat penjualan dan promosi untuk mengelola dan memanfaatkan sampah menjadi barang yang bernilai. Di aplikasi ini juga terdapat wadah informasi tentang seputar pengetahuan cara pengelolaan dan pemanfaatan sampah. Kemudian terdapat wadah untuk membantu para masyarakat yang membutuhkan dengan cara berdonasi dan mendapatkan point/reward dari bermain game yang dapat ditukarkan menjadi uang.

Penelitian ini bertujuan untuk menggali konstruksi sosial tentang pekerjaan pemulung di Tempat Pembuangan Akhir (TPA) Pakusari, Kabupaten Jember, Jawa Timur. Penelitian ini dilakukan dengan menggunakan pendekatan kualitatif dan data dikumpulkan melalui wawancara mendalam dengan 4 responden, yang terdiri dari pekerja pemulung, masyarakat, dan pihak terkait. Hasil penelitian menunjukkan bahwa profesi pemulung dianggap sebagai pekerjaan yang rendah dan kurang bergengsi oleh sebagian masyarakat. Namun, para pemulung di TPA Pakusari memandang pekerjaan ini sebagai sumber penghasilan yang penting dan mereka memiliki keahlian khusus dalam mengumpulkan barang-barang bekas yang masih memiliki nilai. Selain itu, para pemulung dihadapkan pada berbagai tantangan, seperti kondisi kerja yang tidak aman, keterbatasan akses ke fasilitas kesehatan dan pendidikan, serta stigma negatif yang melekat pada profesi mereka. Meskipun demikian, para pemulung di TPA Pakusari memiliki strategi dan mekanisme untuk mengatasi stigma negatif dan membangun identitas positif sebagai pemulung.

Os Quintais Produtivos são sistemas de produção de alimentos saudáveis, desenvolvidos no ambiente domiciliar por técnicas agroecológicas que contemplam a Soberania e a Segurança Alimentar e Nutricional (SSAN) em toda a Cadeia Produtiva. A Feira Interinstitucional Agroecológica (FIA) realizada no Instituto Federal de Goiás (IFG), Instituto Federal Goiano (IF Goiano) e na Universidade Federal de Goiás (UFG), no município de Goiânia desde 2019, oferta os alimentos dos Quintais Produtivos das(os) Agricultoras(es) Familiares do Estado de Goiás. E tecendo a intersecção “campo e cidade” surge a pesquisa pela metodologia da pesquisa-ação existencial/integral, com o objetivo de identificar o modo de produção dos alimentos nos Quintais Produtivos das(os) agricultoras(es) familiares da FIA em 2021. Todos os alimentos foram produzidos pelas técnicas agroecológicas, havendo a oferta majoritária de alimentos in natura. Os Quintais Produtivos promoveram a alimentação saudável na perspectiva da SSAN, bem como as vivencias pró agroecologia “com o campo e a cidade”. Entre os desafios, a importância de avançar na Educação Alimentar e Nutricional (EAN) em toda a Cadeia Produtiva para fortalecer e/ou ampliar a produção e o consumo dos alimentos dos Quintais Produtivos. E em âmbito da Coleta de Dados, houve a lacuna do acesso as Tecnologias de Informação e Comunicação (TIC) pelas(os) agricultoras(es) familiares.
Cathode reaction models for Braga-Goodenough Na-ferrocene and Li-MnO2 rechargeable batteries
Authors: Sakai Masanori
Published: May 2023

Braga-Goodenough all-solid-state Na-Fc and Li-MnO2 batteries demonstrate deposition of Na and Li on the cathode during discharge. These reaction mechanisms were investigated in light of the generalized charge neutrality level and the experimental results of Braga et al., and two new types of mechanisms were proposed. The Na-Fc mechanism is represented by a multi-step C[(CE)cC]n mechanism where C is the chemical step, E is the electrochemical step, c is the catalytic (CE) step, and n denotes the number of [(CE)cC] part cycles. The nth cycle corresponds to n moles of Na and Li deposition. For Li-MnO2, two mechanisms were considered. One is the C[(CE)cC]n mechanism which is the same as Na-Fc, and the other is the C[2(CE)cC]n mechanism, which involves two consecutive (CE)c steps. In the C step of (CE)c of both mechanisms, Fc and MnO2 reduce Na+(sf) and Li+(sf) (sf - surface states) to deposit Na and Li, respectively, which are intramolecular charge transfer reactions within the adsorbed molecules. Fc and MnO2 are oxidized to inter­mediates immediately reduced to Fc and MnO2 by their anodes in the subsequent E step. Based on these mechanisms, these batteries' discharge capacity and cathode alkali metal deposition were examined in detail.
