Nahiv İlletlerinin Arap Dili Öğretimindeki Rolü: Osmanlı Medrese Müfredatı Örneği
Authors: Güzel Mehmet Emin
Published: September 2023

İslâmiyet’le birlikte din diline dönüşen Arapçanın korunması ve Arap olmayan Müslümanlara öğretilmesi ihtiyacı, dil çalışmalarının erken dönemde başlamasına neden olmuştur. Gramere yönelik çalışmalar, sadece kuralların tespitiyle sınırlı kalmamış; dilsel olguların neden ve gerekçelerini de kapsamıştır. İlk dönemden itibaren dilciler, “illet” diye adlandırdıkları bu gerekçelerle gramer kurallarını aklî bir zemine oturtmaya çalışmışlardır. Zamanla nahiv ilminin ayrılmaz bir parçası haline gelen illetler, çoğu dilci tarafından özellikle Arap olmayan bireylere dil öğretiminde kullanılmıştır. Bu çalışmada öncelikle illet kavramı, illetlerin dil öğretimindeki rolü üzerinde durulmuş ardından Osmanlı medreselerinin Arapça öğretim müfredatı, nahiv illetleri açısından incelenmiştir. Çünkü ana dilleri olmamasına rağmen Arapça eser yazabilecek kapasitede âlimlerin yetiştiği bu kurumlar, Arapça öğretiminde rol model olmuşlardır. Çalışma sonucunda, nahiv illetlerinin orta ve ileri düzey dil öğretiminde gerekli görüldüğü, bu bağlamda Osmanlı medreselerinde temel dil kurallarını içeren basit metinlerle başlayan dil öğretiminin felsefî ve cedelî nahiv illetlerini de içeren ileri düzey dil öğretimiyle ikmal edildiği görülmüştür.
Israeli Journalism in the Face of Moral-Political Criticism in the Works of Saul Bellow and Philip Roth
Authors: Asscher Omri
Published: September 2023

This article examines a representative case of Israeli publicist responses to the moral-political critique by American Jewish authors, focusing on the reception of Philip Roth’s Portnoy’s Complaint and Saul Bellow’s Mr. Sammler’s Planet. These novels were first published in Hebrew translation in the early 1970s, against the backdrop of a heightened mythologization of Israel in the American Jewish mainstream and concurrently with Israel’s early occupation of the West Bank. Roth’s and Bellow’s works include some highly unflattering images of Israeli militancy and chauvinistic nationalism. Israeli literary critics tended to respond to the authors’ moral-political critique by framing it as inauthentically Jewish or as incorporating non-Jewish influences. In this way, Israeli responses sought to undermine the validity of the authors’ critique by implying a framework of Jewish identity in which Israeli culture was symbolically preeminent. Ultimately, this tendency demonstrates how the subterranean struggle between homeland and Diaspora has informed and infused the conversation among the two Jewish communities with respect to contemporary Jewish ethics and the Israeli-Palestinian conflict.

Published: September 2023

Abstract. Hydroxylamine (NH2OH) and nitrite (NO2-) represent pivotal nitrification intermediates that substantially govern soil abiotic N2O production. Yet, the intricate factors influencing the abiotic formation of N2O from chemical reactions involving NH2OH and NO2- remain uncertain. This study was designed to reveal the impacts of land use type and parent material on soil abiotic N2O production in response to NH2OH and NO2- amendments. Our investigation revealed that land use type exerted no significant influence on abiotic production of N2O with NH2OH and NO2- addition. Nevertheless, the parent material exhibited a notable (P < 0.01) effect on N2O production intrigued by NH2OH addition. Specifically, a markedly higher abiotic N2O production from NH2OH was observed in soils developed from Quaternary red clay than those derived from granite. Subsequent analysis demonstrated that the soils originating from Quaternary red clay displayed significantly higher manganese (Mn) content in comparison to those originating from granite. This finding consistently aligns with the close correlation between the abiotic N2O production via chemical oxidation of NH2OH and Mn content of soil. Furthermore, the site preference (SP) values for N2O arising from NH2OH and NO2- addition were 25–30 ‰ and around 20 ‰, respectively, aligning with the expected ranges characterizing ammonia oxidation and chemodenitrification processes. Our findings provide valuable insight into the distinct influence of parent material on soil abiotic N2O production via chemical oxidation of NH2OH, contributing to a better understanding of the underlying mechanisms, and highlight the significance of soil factors in regulating abiotic N2O production within soil ecosystems.
Digital Dependency as a Burden: Impact of Active Aging for Tech Adoption in Brazil and Chile
Authors: Duque Marília , Otaegui Alfonso
Published: September 2023

Successful aging and active aging policies frame independence in old age as an expectation and a virtue in opposition to the once desired reciprocity between generations. Due to digitalization trends worldwide, mastering digital skills becomes another responsibility for older adults to remain independent. However, this process can create new forms of dependency as support from skilled users – usually the younger generation – is crucial for technology adoption among older adults. This study addresses how older adults may experience digital dependency as a personal failure and a burden upon younger generations. We conducted long-term ethnography among older adults adopting new technology in Brazil and Chile, countries with rapidly aging populations that have implemented aggressive digitalization strategies. The fast digitalization of public services may increase the risks of social exclusion for older adults as the less connected and less skilled age group in Latin America. Contrary to expectations suggested by the research literature, participants preferred to enroll in smartphone workshops instead of relying on their children. We volunteered in smartphone workshops for older adults and mapped the difficulties they face when adopting new technologies and the strategies they develop afterward to use technology while avoiding dependency. Participants may restrict their use of smartphones due to their limited digital skills or claim a lack of interest in technology as a self-defense strategy against appearing ignorant or incompetent. We found that participants preferred relying on friends for support instead, perceiving their help as a form of peer collaboration.
Life Purpose in the Age of the Smartphone: Reflections from Comparative Anthropology
Authors: Abed Rabho Laila , De Vries Maya , Miller Daniel
Published: September 2023

In this paper, we investigate whether there exists in different societies something analogous to the idea of ‘life purpose.’ Drawing on examples from across the entire range of ASSA project field sites, the paper is organised as a spectrum, starting from the case of Japan where ikigai is the most explicit example of having a life purpose and is a commonly used expression. We then argue that, in some regions, such as Palestine, the idea of life purpose is entirely subsumed within religion. This is followed by several cases where social reproduction seems to dominate life purpose, often based on securing the success of future generations. We then turn to more implicit examples of life purpose, starting with Xinyuan Wang’s study of the relationship between the Cultural Revolution and the smartphone revolution in Shanghai. We then examine the case of Ireland where life purpose is extrapolated from a more general expansive cosmology. We end the paper with the possibility that some people in England may see an advantage in not having any sense of life purpose. In the conclusion, we argue that, just as we now recognise that social cohesion does not require the moral guidance of religion, so too is there no need to have a category of life purpose. But, either implicitly or explicitly, most cultures do have a variety of ideals that we might equate with life purpose.

Bağımlılık davranışları (madde kullanımı, aşerme, madde arama) şiddetli alkol/madde kullanımının bağımlılık yapıcı maddeyle ilişkili uyaranlara karşı kişinin hassaslaşarak dikkat yanlılığı geliştirmesiyle karakterize edilir. Bu süreç örtük olarak gerçekleşir. Yapılan çalışmalar dikkat yanlılığının madde aşermesi ve nüks üzerinde önemli bir rol oynadığını göstermektedir. Bu derleme çalışmasında bağımlılıkla ilgili dikkat yanlılığının nedenleri ve sonuçları incelenmiştir. Bu çerçevede öncelikle dikkat yanlılığı ölçümünde kullanılan paradigmalar ile dikkat yanlılığının nasıl araştırıldığı hakkında bilgi verilmiştir. Sonrasında dikkat yanlılığı ile aşerme arasındaki ilişki ve dikkat yanlılığının nüks üzerindeki etkisinden elde edilen araştırma bulguları özetlenmiştir. İlgili literatüre göre, alkol/madde dikkat yanlılığının aşerme ile pozitif ilişkisinin olduğu ve tedavi sonrası nüks riskini öngörebileceği söylenebilir. Araştırmacılar, dikkat yanlılığı ile yapılan çalışmaların bağımlılık tedavisine yararı olabileceğini düşünmektedir. Dikkat yanlılığının, aşerme seviyesini azaltma ve nüksü önlemede kullanılabilecek bir araç haline getirilmesi klinik alanda bağımlılık tedavisi için umut vaat etmektedir. Ancak, dikkat yanlılığının sahada kullanılabilir hale gelebilmesi için daha fazla teorik bilginin geliştirilmesine ve metodolojik eksikliklerin giderilerek yeni araştırmaların ihtiyaç duyulduğuna vurgu yapılmaktadır.
Lateral tibial plateau fractures with posterior comminution. Can a rim plate offer sufficient support?
Authors: ANDONOV Yordan
Published: September 2023

Tibial plateau fractures with posterior comminution are difficult to reduce and stabilise. Standard lateral approach doesn’t offer adequate visualisation. Posterior approach is suitable for isolated posterior fractures. The addition of a specifically contoured rim plate can enable fixation of posterior fragments through a modified lateral approach.The purpose of this study was to evaluate the advantages and limitations of this novel technique. We present a prospective series of 16 tibial plateau fractures with posterolateral depression, operated over a period of 7 years (04.2014-09.2021). The mean age of the patients was 52 years .They were followed for an average period of one year.Clinical and functional assessment was performed according to the criteria of Knee Society Clinical Rating Score. The lateral and posterior component of the fracture was stabilised by a horizontal rim plate, through a posterolateral approach, with or without fibular osteotomy. 9 patients had excellent, 5 had good, 2 had average ratings. The average objective rating was 87,5 (70- 97), and the average functional rating was - 74,4 (40-100). The average ROM was 110° (100°-120°). Two of the fractures healed in 5° varus and 8° valgus respectively. One knee joint ended up with 10° flexion deficit. Three knees had medio- lateral instability, with no functional impairment. In 4 cases the K wires of the weber fibular osteotomy fixation migrated. The absence of late articular collapse of the treated fractures may be attributed to the initial stability of fixation.The addition of a rim plate addresses the posterior comminution and makes early rehabilitation safe.

Published: September 2023

The lateral tibial spine (LTS) is frequently proposed as a correction target in high tibial osteotomy (HTO), although little is known about its exact radiographic position. This study primarily aims to define the position and variance of the LTS. Secondly, this study wants to investigate the relevance of the LTS position on the mechanical tibiofemoral angle (mTFA°) while planning and postoperatively landing the weight-bearing line (WBL) on this landmark. The LTS position was studied on preoperative full-leg standing radiographs (FLSR) and computed tomography (CT) scans in 70 cases. 3D models of the tibia were created in Mimics 23.0 and measurements were conducted in 3-matic 15.0 (Materialise, Leuven®). Next, 100 HTO cases were retrospectively planned with the WBL through the LTS according to Dugdale’s method on FLSR. Finally, 55 postoperative FLSR which had the WBL on the LTS (±2%) were assessed for mTFA° outcome. Statistics were conducted in GraphPad 8.0. The LTS was located at 58.3%±1.9 [55-63%] in 2D and 57.3%±2.2 [53-63%] in 3D showing a high correlation (r=0.77 [0.65 to 0.85]). The planned mTFA on the LTS was 181.8°±0.3 (181.3°-182.5°). On postoperative FLSR, the mTFA was 182.2°±0.6 (180.9°-183.1°). The lateral tibial spine is located at 57-58% on the tibial plateau with a 10% maximal variation range. Good agreement was found between 2D and 3D imaging modalities while evaluating its position in the coronal plane. When aiming the WBL through the LTS during valgus-producing HTO, a consistent realignment of 181-183° mTFA can be expected when performing accurate surgery.

Published: September 2023

The aim of this retrospective study was to evaluate the potential bony erosion and the clinical and radiological results of primary trapeziectomy with RegjointTM interposition, in patients with peritrapezial arthritis. Data were recorded on twenty patients over a period of two years (January 2015-December 2016). On average 24 months, patients were reconvened for a post-operative evaluation (subjective evaluation of pain, function and patient satisfaction; clinical evaluation with strength and mobility measures; post-operative X-rays). On X-rays, 2 criteria were evaluated: the bony erosion and the shortening of the thumb column (trapezium+metacarpal height measure, ratio between first and second metacarpal bones, a new radiological assessment tool based on a trapezoid relationship gradation). In most patients, surgery relieved pain and offered good functional results, according to the Quick Disabilities of the Arm, Shoulder and Hand scale. Following surgery, our patients showed a subjective improvement, both in terms of pain and functional results. For plain X-ray, only 3 patients showed an osteolytic lesion (maximum of 2.8 millimeters) on the first metacarpal base. A statistically significant reduction in the thumb column height was generally observed on follow-up X-rays. However, all of these radiologic changes were present without any clinical impact. We show that the RegjointTM spacer is an available alternative in the surgical treatment of peritrapezial arthritis. We did not highlight any significant associated complications, no important adverse tissue reaction or bone erosion, no pain or functional disorder.

Atomization in Forensic Applications and Aerosolization in Dentistry
Authors: Yarin Alexander
Published: September 2023

The talk discusses two inter-connected atomization and aerosolization-related situations.
Keywords: (1) Biomedical, biological and bio-mimetic, (2) Miscellaneous

1. The first one arises in relation to the blood pattern analysis (BPA) in forensic applications, where a pattern of blood stains on the crime scene is used to determine the origin of blood spatter. Here, it is shown that blood drops resulting from gunshots form due to the Rayleigh-Taylor instability, which occurs in backward spatter because the denser blood is accelerated toward air. The subsequent evolution of backward spatter is treated as a system of two-interpenetrating continua, with a blob of blood droplets propagating through air experiencing gravity force, as well as aerodynamic drag, producing viscous suction and causing air entrainment. The leading blood drops experience the highest drag and entrain air in their wake, which results in the collective effect reducing the air drag experienced by the subsequent drops. The secondary, aerodynamically-driven atomization also pays significant role. The results also reveal a significant interaction of the backward blood spatter with the oncoming self-similar turbulent vortex ring of propellant muzzle gases in short-range shootings. It is shown that there is even possibility that a blood drop from the backspatter will fully turn around by a powerful vortex ring and land behind a victim, which is confirmed experimentally.
2. The second situation arises in dentistry where cavitron scalers severely aerosolize the irrigation water in contact with a tooth and a scaler vibrating at the frequency of 30 kH. Formation of droplets in this case is caused by the Faraday instability and is responsible for aerosol transmissibility of SARS-CoV-2 and other viruses and bacteria, which become airborne. The present work explored this situation experimentally and theoretically and introduced a novel approach, which remediated this dangerous situation and already found practical applications in dentistry. By altering the physical response of water to the ultrasonic forces by miniscule concentrations of FDA-approved polymers and thus, introducing viscoelasticity, the generation of aerosol droplets and the distance any aerosol may spread beyond the point of generation can be markedly suppressed or completely eliminated, which made dental procedures safe again.

La lechuga hidropónica se cosechó a los 70 días, mediante este ciclo de producción se puede obtener 9 ciclos productivos por año de lechuga hidropónica. Para la relación beneficio/costo el tratamiento dos (T5) con altura de suspensión a 1 cm por densidad de trasplante de 20 cm (A1*B2) con mayor ganancia B/C de 1.55, el (T4) con altura de suspensión de 1 cm por densidad de trasplante de 15 cm (A1*B1) con B/C 1.30; los demás tratamientos tienen beneficio/costo menor a 1, por lo que no son económicamente rentables.
Synthesis and evaluation of mutual prodrugs of some NSAIDs
Authors: Manish S. Junagade  , Anju Goyal
Published: September 2023

The therapeutic efficacy of NSAIDs can be improved by reducing their gastrointestinal side effects by modifying their carboxyl group. Anti-inflammatory drugs Ibuprofen, Ketoprofen were chosen for the preparation of mutual prodrugs with paracetamol. The compounds were synthesized with the aim of achieving a synergistic effect and reducing the gastric irritation of anti-inflammatory drugs. Compounds were confirmed by characterization. The synthesis involved an esterification reaction between the carboxyl group of selected NSAIDs and the hydroxyl group of paracetamol. Mutual prodrugs were evaluated for hydrolysis study in acidic medium and phosphate buffer. Compounds were found to hydrolyze at a controlled rate in the environment, and thus this study found that a mutual prodrug approach can be effectively used to achieve the goals of enhancing the effectiveness of NSAIDs in two ways. First, by masking the carboxyl group of NSAIDs to reduce GI effects and achieve synergistic effects using paracetamol as a pro moiety. Both IP and KP prodrugs were retaining anti-inflammatory activity intact and exhibited much-reduced gastric irritant activity. Prodrug IP however, showed better activity and negligible ulcerogenic tendency than KP.

During last years, lung cancer treatment has rapidly changed thanks to novel drugs, such as immunotherapy and target therapy. Hence, an improvement of life expectancy, notwithstanding with a higher infectious risk. This is probably due to many factors, such as longer survival and immunosuppression; furthermore, novel drugs could increase infectious risk with different biologic mechanisms. However, correlation between infections and immunotherapy has not been completely clear, although lately has increasingly been described. Salmonella enterica spp is an intracellular facultative anaerobe gram-negative bacillus that can spread to different sites, such as lung and pleura; nevertheless, an association between lung cancer and pleural empyema due to salmonella infection is rarely highlighted in literature and its management is challenging. Hereby we outline the case of a 62-year-old woman affected by extended lung adenocarcinoma who developed salmonella-related pleural empyema during its active oncological treatment with chemo-immunotherapy by describing our multidisciplinary management model.

forest flora in the life and economy of the tribals of santhal parganas, jharkhand
Authors: Singh C.
Published: September 2023

The forest of Santhal Parganas (Jharkhand) is rich in the diversity of flora. Its extant flora affords the basic needs of the tribals living amidst the forest for centuries. The tribals put the forest flora and its parts/ products in their diverse domestic uses as food, fuel, fodder, fibre, bamboowares, timber, medicine, oil, fish poison, etc., and also they sell these things to earn money. To sustain both the surviving forest as well as the tribals dwelling therein, it is imperative to stop deforestation, set up/encourage forest-based labour intensive works (sabai grass-based rope making industry, bamboo-based basketry, fruit-based preservation industry, bidi industry, lac-tasar-mulberry silk culture, gum-resin-dye extraction, eating plate preparation, etc.) and emphasize plantation as per preference of the tribal race of the concerned area.
Research on the Comparison of Sampling with and Without Replacement in Quality Control Test
Authors: Yang Yilin
Published: September 2023

The choice of a reasonable and scientific sampling method and the implementation of efficient quality control tests can help companies achieve economic and social benefits. In this paper, probability theory and statistics are applied to provide a basis for enterprises to consider the choice of sampling with and without replacement through case studies and modeling. These two sampling methods lead to binomial and hypergeometric distributions of probabilities, respectively. The differences between them are found to be negligible in the case of large population size by calculations at N. Based on comparison of sampling methods, this paper further divides the manufacturing industry into the chemical industry, which is sensitive to the reliability of quality control test, and other manufacturing industries, which are more sensitive to cost while controlling quality. In the end, suggestions are proposed for improving quality control tests for the category industries respectively.
Small and Medium-sized Enterprises Private Equity Risk Management
Authors: Hou Xiaoyang
Published: September 2023

Small and medium-sized enterprises are playing an important role in Chinese economic development. However, due to the lag in system construction, the scale of small and medium-sized enterprises is relatively small; many of these enterprises lack funds, and it is difficult to get loans. The financing difficulty of small and medium-sized enterprises always exists in China, which has become an important reason restricting their further development. In the past, smes used to borrow money from banks to finance their development. They have been borrowing from banks with their assets as collateral, but as the country has adopted a tight monetary policy, most of the loans applied for by smes have been rejected by banks.
Private equity fund has the characteristics of low financing threshold and high added value of enterprises, helping many small and medium-sized enterprises to solve the capital problem, enabling them to develop and grow. In the process of private equity fund financing, the macro environment and micro factors bring huge risks to the whole financing process. Therefore, it is necessary to evaluate, analyze and control every risk that may cause financing failure in the financing process.
This paper uses the method of literature review, qualitative and quantitative combination, through the construction of small and medium-sized enterprise private equity fund investment risk evaluation index system, from the micro and macro environment to evaluate and analyze the risk, for the analysis of small and medium-sized enterprises may face financing risk to provide effective avoidance measures.
The Influences of Pricing Based on Consumer Preference---Taking the Hype Shoes Phenomenon as an Example
Authors: Wang Xuncheng
Published: September 2023

In recent years, the phenomenon of hype shoes has attracted more and more attention. The hype shoes uses consumer preferences to make special pricing and make money on the price difference. To understand how consumer preferences influence pricing strategy, many studies have dissected consumer preferences from the producers perspective. In this paper, we analyzed whether a firms pricing strategy is reasonable from an economic perspective, and also clarify the importance of consumer preferences in business competition. There are many economic principles behind this phenomenon and it is worth reflecting on them. Studies have found that consumers age, gender, occupation and even body size can be used as pricing factors by businesses. Therefore, once a company has more information about a consumer, it can provide personalized services to the consumer, and on the other hand it may use big data discriminatory pricing (BDDP) to earn more money. Through the analysis of the hype shoes phenomenon, businesses should learn to correctly grasp consumer preferences and then raise pricing appropriately based on cost. Finally, businesses should know how to properly invest in market research to obtain more consumer data and ultimately adopt a successful pricing strategy.

Authors: Wang Yi
Published: September 2023

With the accelerated integration of the world economy and the gradual development of Chinas reform and opening-up, Chinese enterprises have been making outbound investments and cross-border mergers and acquisitions more frequently. In terms of the attitudes of countries around the world towards the entry of foreign capital, some countries welcome the entry of foreign capital. However, others restrict the cross-border M&A of foreign companies entering their countries for reasons of domestic resource, technology and industrial protection, or to protect the interests of their national industries. From the recent development trend, the national security of foreign capital is especially cleared. Hence, this paper mainly studies the national security clearance system of cross-border M&A in the United States and other developed Western countries through literature analysis and comparative analysis. It also tries to summarize the characteristics and rules from them in the light of China's national conditions, supplemented by systematic research on cases of failed cross-border M&A by Chinese enterprises that encountered national security. Based on this, it will be very beneficial to the future cross-border M&A activities of Chinese enterprises, laying a good foundation for Chinese enterprises in the world M&A field in the future.
Price dispersion in the phenomenon of big data discriminatory pricing (BDDP)
Authors: Qian Yuxuan
Published: September 2023

Theoretically, competition between firms producing homogeneous products would lead to price convergence. However, there is persistent price dispersion in real markets for homogeneous products. Many scholars have built models from different perspectives to explain the existence of price dispersion in retail markets. Moreover, this price dispersion still exists after entering the Internet era. My paper builds a model based on the phenomenon of many monopolies charging different prices to consumers through big data discriminatory pricing (BDDP) since entering the Internet Big Data era to find price dispersion equilibrium from the perspective of firms. My model adds some variables to a Varian-style model in which consumers are divided into three types and firms charge different prices to maximise profits. Moreover, my study simplifies the actual market situation and is theoretically ideal. It does not perform a multi-stage analysis of consumer switching costs and consideration of consumers entering and leaving the market. However, my paper provides some ideas for subsequent research on price dispersion in Internet monopolies and provides a direction for multi-stage research.
A Survey of Availability Heuristics in Behavioral Economics and Its Application Analysis
Authors: Zhang Jiayi
Published: September 2023

Early in the 1990s, significant advancements were made in our understanding of the availability heuristic. Following that, economist Howard Kunreuther discovered that availability effects contribute to the explanation of the trend of insurance purchasing and sparing actionafter disaster during the initial phaseof his profession investigating risk and insurance. The most significant research on availability biases was done in Eugene. They conducted ground-breaking research on how people perceive risks, including a study that has come to serve as the paradigmatic illustration of an availability heuristic [1]. This paper introduces the concept of the availability heuristic in behavioral economics, outlining the development of the theory and its importance. At the same time, this study demonstrates through three applications (investment decision, advertising, moral strength, and ethical decision-making). These three applications prove that if the availability heuristic is triggered, people will focus on facts that is current or readily recalled rather than analyzing every relevant details. As a result, this will increase the likelihood of an incident or the occurrence of a group they assess.

Published: September 2023

This paper makes an event study on the Russo-Ukrainian War effect of the stock return, including that of the S&P500, renewable energy industry, military industry, and catering industry, with a time window of 29 days (39 days for Teslas event). This article will gain the normal and abnormal returns by using linear regression and the least square method. Then, the hypothesis test will be conducted using the Summation of the abnormal rate of return (CAR). The result will be shown by whether the cumulative abnormal return breaks the confidence interval according to the graph. Research results show that even though the war harms the economy, it does not entirely reduce the stock return. This empirical study would be helpful for the investors to make their investment strategy during the War period.

This paper will compare the results of the implementation of the two-child policy and the three-child policy. To be specific, this study will explore the impact of the population birth policy on the urban real estate market through urban classification, as well as the demographic dividend brought by the birth policy and changes in the structural demand for real estate. According to the analysis, real estate companies in the implementation of the two-child policy have faced new challenges and new opportunities. In the future, the birth policy will affect the family structure. This will further influence the development direction and project development of the real estate market.
The Governance Model Investigation of Urban Village's Commercialization Based on Cultural Insight
Authors: Yang Yaru
Published: September 2023

With the development of the city, urban villages, though an important part of the cities now, seem to be unable to avoid the fate of disappearing. Urban villages developed in China as a result of some original villages being surrounded by contemporary tall buildings. This paper reviewed the history and the development of urban villages, compared slum management in other countries to the management of urban villages in China, and takes Nantou Gucheng, an urban village in Shenzhen, as an example to explore the balance between economic development and preservation of cultural heritage. The paper shows that the urban village provided stalls for the brands like a commercial center, which was meaningless. The government should dig deep into the history of the urban villages. Besides, the government makes it possible to provide improved support to ensure old shops run by the original residents of urban villages for more than 10 years can continue to operate.
Event Study: The Effect of the Passing Away of Queen Elizabeth II on the UK Stock Market
Authors: Li Xinran
Published: September 2023

This study assesses the heterogeneous impact of the death of Queen Elizabeth II on industry leaders in the United Kingdom. It reveals the firm-specific characteristics that lead to this heterogeneity. This study applies an event study methodology to a sample of 20 leading UK companies across a 250-day estimation window and a 40-day event window. According to the event study, the death of Queen Elizabeth II has had a differential impact on most UK companies for different industries. In contrast, companies in the Biotech, Oil & Gas, Mining, and Tobacco industries were less affected. However, companies in the Retail, Telecommunications, Banks, and Defense Contractors sectors show significant negative CARs. This article has implications for investors in identifying company sector-specific characteristics that drive premium returns and guiding diversification by improving the sectoral diversity of portfolios. However, the study is limited by a relatively small sample size. There is a gap in earlier research on the related change of kingship and stock market performance, and this study makes two contributions to the literature. The authors first analyze the impact of the death of Queen Elizabeth II on British firms. Secondly, the study also provides guidance on how investors can diversify across different sectors in the UK to reduce risk.
