Multiple Owners Research Articles

MULTIPROPRIEDADES – PROCEDIMENTOS REGISTRAL

The objective of this article is to analyze the registration procedures related to timeshares, a model of shared ownership in which multiple owners have rights to the same property. The research seeks to understand how registration procedures influence the legal security and management of these ventures. The methodology adopted is a literature review. The research is based on a critical analysis of books, academic articles, and relevant legislation on timeshares and their registration procedures. The review is conducted to identify the main challenges, practices, and regulatory standards that impact the registration and management of timeshares. The review covers topics such as the evolution of timeshares, comparisons between different jurisdictions, and current legislation. The reviewed literature shows that timeshares are a model that has grown with tourism and that requires clear registrationto avoid conflicts. The legal and administrative challenges that arise in the practice of registering these ventures are also discussed. The expected results include an in- depth understanding of the registration procedures involved in timeshares and their implications for the legal security of investors. The aim is to identify gaps and areas that require improvements in legislation and registration processes. The results should provide recommendations for improving procedures and creating clearer and more effective guidelines. The conclusion of the article should demonstrate that registration procedures are crucial to the success of timeshares, providing a solid basis for the legal security of those involved. It should be noted that, despite advances in regulation, there are still significant challenges that need to be addressed. It is recommended that standardized practices be implemented and that laws be updated to better meet the needs of this property model.

Prism: Privacy-Preserving and Verifiable Set Computation Over Multi-Owner Secret Shared Outsourced Databases

Private set computation over multi-owner databases is an important problem with many applications — the most well studied of which is private set intersection (PSI). This paper proposes <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Prism</small> , a secret-sharing based approach to compute private set operations ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">i.e.</i> , intersection and union, as well as aggregates such as count, sum, average, maximum, minimum, and median) over outsourced databases belonging to multiple owners. <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Prism</small> enables data owners to pre-load the data onto non-colluding servers and exploits the additive and multiplicative properties of secret-shares to compute the above-listed operations. <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Prism</small> takes (at most) two rounds of communication between non-colluding servers (storing the secret-shares) and the querier for executing the above-mentioned operations, resulting in a very efficient implementation. <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Prism</small> also supports result verification techniques for each operation to detect malicious adversaries. Experimental results show that <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Prism</small> scales both in terms of the number of data owners and database sizes, to which prior approaches do not scale.

Enhancing Secure and Reliable Data Transfer through Robust Integrity

Cloud computing has emerged as a highly efficient platform that allows multiple users to access various services through virtualization on a shared physical network. The participants in a Cloud Computing (CC) environment include Cloud Service Providers (CSP), Consumers, Brokers, and Auditors. The advantages of cloud storage, such as universal network access, convenience, and scalability, have led to data owners preferring to store their data on remote servers. However, the transfer of outsourced data has become a critical requirement for cloud users due to the availability of different cloud storage services with varying quality of services.&#x0D; One major challenge in this context is ensuring the security of secret keys and data integrity. There is no guarantee of data integrity when storing data on an untrusted cloud server. To address this issue, this paper proposes a secure and efficient data integrity verification scheme for cloud storage services. The scheme utilizes a key-homomorphic cryptographic primitive to reduce system complexity and eliminate the need for a public key authentication framework based on a public key infrastructure (PKI) in the data integrity checking protocol. By employing this approach, the proposed method ensures the integrity of remote data stored on cloud servers. Through security analysis and empirical evaluation, it is demonstrated that our scheme is both practical and effective for securely sharing records with multiple owners in cloud computing.

Exploring the imprint of the institutional context on the urban network in China: Comparative analyses between corporate‐based networks with different ownership structures

AbstractWhile the link between the urban network and institutional context has been well established, there has been less work on the effect of shifting political economy on the mechanism of its intercity flows. In this paper, the investment dataset of Chinese publicly listed firms is used to construct corporate‐based urban networks with different ownership structures. Two straightforward but effective comparative analyses are conducted. The first distinguishes between networks formed by state‐controlled and nonstate‐controlled firms, and the second distinguishes between subnetworks formed by central‐ and local‐state power. By surveying the distinctions from the perspectives of state–market relations and central‐local government relations, we argue that the urban network in China is shaped by the varied forms in which the central government, local governments, and the private sector interact. To gain a more proper knowledge of the geographical patterns, this research recommends further field research into enterprise‐based linkages of multiple ownership.

Socio-ecological status of marine ornamental reef fishery in Trincomalee, Sri Lanka - An application of strategic SWOT analysis

The present study elucidates the socio-ecological status of the marine ornamental reef fish (MORF) fishery in Trincomalee, Sri Lanka, through strategic SWOT analysis. Data were collected through interviews with full-time fishers (n = 49) fishing at Pulmodai, Sampur, and Kuchchaweli reef sites, focus group discussions (n = 3), and participant observations during 2019–2020. Data gathered in-situ were further investigated in detail, analyzed, and grouped into attributes of SWOT analysis. Results revealed higher fishing income (90–900 USD) by 91.84% of respondents as the major strength of the fishery, followed by low production costs (24–240 USD), a low labor force, and others. Seasonality of the fishery, multiple ownership of reefs, and the limited number of fishing hours (4-6 hrs.) were the main weaknesses identified in the system. High global demand, the fish-to-order concept, and the intervention of local buyers were the major opportunities for the fishery. Long market chains, bopyrid isopod infection on Pacific cleaner shrimp, and poor monitoring systems were the major threats to the industry. The MORF fishery in Trincomalee, Sri Lanka, results in higher living standards for fisher communities and empowers them. The present study has policy implications for the MORF fishery and the long-term sustainability of the industry.

IMPLEMENTATION OF SHARIA ECONOMIC PRINCIPLES IN THE GLOBALIZATION ERA

The globalitation era is an era that requires people to quickly adapt to the times that are increasingly advancing rapidly. Because if it is not adaptive it will be a human being left behind. While the era of globalization demands a tight contestation. Especially in the economic sector. Every global company has its own strategy in marketing its business. They don't think about the fate of their competitors. That's because they think that other companies are tough competitors. So that their competition prioritizes individual (company) profits and stops other companies that have the same business product. Of course, this global business competition is contrary to the principles of Islamic economics. Which, the principles of Islamic economics are not solely seeking individual gain. But also think about mutual benefits. Therefore, there are at least three Islamic economic principles that must exist even in the midst of global business competition, namely multiple ownership, freedom to act, and social justice. These three basic principles of Islamic economics must still exist in economic behavior and remain relevant even in the midst of global economic contestation.

Assessment of the Livelihood Status of the Carp Fish Farmers in Two Unions of Puthia Upazila Under Rajshahi District, Bangladesh

Nowadays, carp culture has become an important sector in terms of nutrition supply, income generation, and increasing scope of employment in Bangladesh. The present survey was conducted to evaluate the livelihood condition of the carp fish farmers in the Shilmaria and Valukgasi unions of Puthia upazila under the Rajshahi district. The survey was done for a period of 6 months from January to June 2023. All the necessary data were collected through a structured questionnaire. Sixty farmers were included in this study. Thirty farmers were taken from the Shilmaria union and another thirty farmers were taken from the Valukgasi union. All of them were involved in carp fish farming. The average pond size of the study area was 0.35 ha. The ponds are belonging to both single (23%) and multiple ownership (77%). The majority of the carp farmers were under the age group of 41 to 50 years and had a level of education up to primary (23%). Most of the farmers were Muslims (98%) and few of them were Hindus (2%). The annual incomes of the majority of carp farmers (30%) were above Tk. 1,00,000. Sixty-seven percent of the carp farmers used semi-pucca sanitary, 22% used pucca sanitary, and 12% used kacha sanitary. Among the sample farmers, about 32% had half-building house while 14%, 11%, and 3% of the farmers had tin shed, building, and kacha house (made of mud and straw) respectively. Ninety-eight percent of the carp fish farmers availed of electricity facilities and 2% of them did not have. Most of the carp farmers (92%) used their tube well, while a few numbers of them (8%) used a neighbor's tube well for drinking water. About 60% of the carp farmers took health services from village doctors, 22% went to the upazila health complex, 8% went to the district hospital and 10% had access to the MBBS doctors in private clinics. The major constraints were the lack of scientific knowledge, the high price of fish feed, and a lack of capital for carp fish culture. So, the livelihood status of the carp fish farmer can be increased through proper training on carp fish culture and providing additional Government and Non-Government support.

FingerChain: Copyrighted Multi-Owner Media Sharing by Introducing Asymmetric Fingerprinting Into Blockchain

Nowadays, more and more people are engaged in media creation and sharing for income. A common way to earn income is to upload media to an intermediary platform and then let the platform distribute some profits. However, intermediary platforms generally not only extract most of the profits, but also lack transparency in their operation, where owners lose direct control over the media. Nevertheless, individual sharing is not feasible for owners because each owner holds too little media to attract enough users independently. Blockchain is a solution to the above problem by gathering media from multiple owners without intermediaries. Though a lot of works have studied the use of blockchain for decentralized management of media data, many of them either did not consider sharing needs or tracing the illegal redistribution by malicious users. As for other works, most of them adopted symmetric digital watermarking in their blockchain networks, and thus fail to protect the rights of users who may be framed by malicious owners. Although asymmetric watermarking has been used by two existing works, the owner-side embedding pattern results in low owner-side efficiency. In view of this, we design a media sharing blockchain network in which the asymmetric fingerprinting (i.e., watermarking) with user-side embedding is introduced. Besides superior owner-side efficiency, our scheme also outperforms the above two ones in terms of TTP-free. Moreover, our scheme is designed to offer a user-friendly experience and support record traceability. The performance of our scheme is verified by both theoretical and experimental evaluations.

An Efficient and Secure Method for Simultaneous Ownership Transfer of Multiple Mobile Readers

In recent years, radio frequency identification technology has developed rapidly and has been applied in supply chains. Products in supply chains are varied and may belong to several different owners. Ownership transfer requires the consent of a majority of owners. This article proposed a method suitable for simultaneously transferring the ownership of a large number of goods. The method does not require a trusted third party and can securely and efficiently transfer group ownership for multiple owners with multiple tags. The old and new owner groups can be classified as different authorities. This method can be used in mobile readers to transfer one, some, or all tags in a group. It includes mutual authentication between tags, readers, and backend servers, and can ensure that only assigned owners can obtain the tag ownership. The method proved can resist most known attacks, such as secret disclosure attacks and replay attacks. It can also prevent attacks from the dishonest original owners. Finally, through experiments, we compared the proposed method with other many-to-many ownership transfer methods and demonstrated that the proposed method has better security and fewer transmitted messages than other methods.

Blockchain-Based Accountable Auditing With Multi-Ownership Transfer

Cloud auditing enables the integrity verification of cloud data without the necessity of data retrieval, which significantly promotes the storage service of cloud computing. Auditing with ownership transfer is a variation where both cloud data and the tags for integrity verification can be transferred. In some scenarios, like joint-stock enterprise acquisition and electronic medical records migration, we argue that auditing and transferring data belonging to multiple owners are significantly important. However, to the best of our knowledge, there exists no such protocol in multi-ownership scenarios in the literature. In this paper, we propose a blockchain-based accountable auditing protocol with multi-ownership transfer for the first time. One distinguishable property is the simultaneous achievement of verifiability, accountability and multi-ownership transferability, merely with very little extra cost. Specifically, we construct a novel tag structure based on homomorphic authenticators and compact multi-signatures, enabling integrity verification and multi-ownership transfer. Subsequently, we record the information concerning data generation and ownership transfer on immutable blockchains to make these procedures accountable. Furthermore, we present a comprehensive analysis and extensive experiments to demonstrate the security and efficiency of the proposed protocol.

Towards Strong Privacy Protection for Association Rule Mining and Query in the Cloud

Efficiently mining frequent itemsets and association rules on the encrypted outsourced data remains a great challenge for the time-consuming ciphertext computations. Nowadays, it has been not well addressed for privacy-preserving frequent itemsets and association rule mining schemes with mining efficiency, dataset, and query confidentiality simultaneously. In this paper, we investigate the study of privacy issues on frequent itemset mining and association rule mining on outsourced data in a two-cloud model, where the data are encrypted and outsourced by multiple owners holding different public keys. We develop several secure computation protocols based on additively homomorphic cryptosystem and additive secret sharing, which enable the clouds could securely mine the frequent itemsets and association rules. Furthermore, we also design two kinds of frequent itemset and association rule query service models, i.e., service customers query the cloud-mined results, and service customers query with their own decided threshold. The proposed scheme not only supports the mining process on the data encrypted by multiple public keys without compromising the security of the datasets, query data and query results, but also offline users. In addition, the experimental results show that our query scheme is much more efficient than the state-of-the-art work.

Agricultural Development in Comprehensive Village Development Program (CVDP) Area and Non-Comprehensive Village Development Area of Comilla

Purpose: This study compares the effectiveness of the Comprehensive Village Development Program (CVDP) and Non-CVDP models in the context of agricultural development in rural Bangladesh. The roles played by cooperative institutions in CVDP and non-CVDP villages in agricultural development initiatives based on agricultural extension in terms of the status of crops, vegetables, livestock, poultry, and fish farming so that the Bangladesh government can concentrate on the value of the CVDP model and implement it in the underdeveloped rural area.&#x0D; Data and Method: The secondary data used in this research were gathered between 1990 and 2017 and provided in the form of tables and charts. The study's results are interpreted using the percentage approach. The purposive sampling technique is used to emphasize qualitative and quantitative analysis. Information is gathered from BARD, books, journals, and government reports.&#x0D; Findings: The results of the study demonstrate that improved agricultural techniques, including the use of fertilizers and insecticides, were used in CVDP communities. However, there were no appreciable differences in the rice yield between CVDP and non-CVDP villages. Utilization of irrigation and realization of water charges have both increased in the CVDP zones. In all the communities, sophisticated farming machinery was utilized. The villages participating in the CVDP have established sales networks and expertise in raising livestock and poultry. Multiple ownership, theft, fish poisoning, etc. affected pond fish firming more in non-CVDP communities than in CVDP villages.&#x0D; Practical Implications: The government may be able to restructure agricultural extension developments in Bangladesh according to the CVDP model with the help of the data gathered from the research once again.&#x0D; Research Limitations: It is difficult to use recent data in the analysis due to a lack of past research on the topic in Bangladesh, limited access to relevant areas, and the absence of new studies in this field.&#x0D; Value: The findings of this study complement those of earlier research that could not examine variances in agricultural growth (in terms of the output of agro products including rice, vegetables, cereals and vegetables, livestock, poultry, etc.

EFFECTIVENESS OF CORPORATE MANAGEMENT: CURRENT PROBLEMS AND PERSPECTIVES

Corporate governance is the basic form, which involves combining the interests of various stakeholders. In the process of transformation of the economy, the main goal was the formation of the private sector and the development of entrepreneurship. Privatization played an important role in achieving the mentioned goal. The process of privatization of state property is a result of the current globalization in the world. One of the main tasks of privatization is the formation of a corporate system of ownership. That is why the result of the mentioned process should be improved and highly technologically developed services, increased production and financial efficiency. Accordingly, the process of ownership redistribution will be a normal and effective mechanism of corporate control when the efficiency of the corporations' activities will increase and, accordingly, economic growth will take place. Unfortunately, such processes were more the exception than the rule in Georgia. Thus, we can unequivocally state that privatization could not solve the main task - to increase the efficiency of the work of newly created joint-stock companies. It was expected that owners interested in more efficient management would emerge. But the emergence of multiple ownership instead of one owner - the state, had a weak effect on the increase in the effectiveness of the internal management mechanisms and its results. At the same time, the ability to promptly resolve issues of ownership and overall strategic leadership has become significantly more difficult. One of the main reasons for this is that effective corporate governance mechanisms were not offered alongside the increase in ownership.&nbsp

Fractured Ownership and the Tragedy of the Anticommons in Hawai‘i

AbstractThe decline in the number of Native Hawaiian–owned kuleana properties is partly the result of legal frameworks surrounding heirs' property adjudication, which does not easily allow families with multiple owners to collectivize their interests. As a result, families are made vulnerable to land dispossession by developers' use of quiet title and partition actions through the courts. Based on fieldwork that incorporates ethnography and archival research, I explore the disjunction of kin‐based patterns of inheritance within a culturally Western legal framework that values one owner, one property scenario. A novel analysis of heirs' property reveals the extent to which current legal doctrine is inherently unsuited to address both real and intangible inheritance patterns, thereby creating property and wealth destruction characteristic of a tragedy of the anticommons.

Secure Cloud Storage Privacy-Preserving In Public Auditing

Cloud computing is a technology that is both efficient and cost-effective, thanks to its low maintenance requirements. This paper implemented a approach is used to share group resources across cloud users. Regrettably, as a result of the frequent differences in participation, the issue of sharing information in a multi-owner manner while also preserving privacy and information from a trusted cloud continues to be a challenging one. During the course we put into place a safe method of data sharing among multiple owners using the Diffe- Hellman algorithm that are cloud-based and applicable to rotating groups. By leveraging techniques like as group signature and dynamic broadcast encryption, any user of the cloud has the ability to anonymously share data with other users. In the meanwhile, the number of users whose access has been revoked does not have any impact on the storage overhead or encryption computation costs associated with our system. In addition, employ rigorous proofs to investigate the scheme's level of safety, and conduct tests to verify the scheme's usefulness.

Scan-free verifiable public-key searchable encryption supporting efficient user updates in distributed systems

Searchable encryption (SE) is a promising technology that provides search functions while preserving information privacy. A small number of SE schemes can be applied to a distributed system. In such systems, multiple owners provide data that is encrypted by their secret keys to the system for retrieval by users. In this setup, however, users need to scan a searchable index for retrievals, which leads to linear search complexity. Moreover, updates of users (e.g., revoking an expired user from the system) generally incur substantial overhead to re-build the index. Accordingly, we propose a scan-free verifiable public-key searchable encryption scheme with an efficient user update function in a distributed system (i.e., in a multi-owner multi-user model). First, owners self-select secret keys to encrypt keywords. A master secret key is designed to support keyword searches among these keys. Additionally, a searchable index with an implicit relationship between the same keyword is proposed. There is no need to scan the index for keyword retrieval, which achieves sub-linear search complexity. It is also important that the updates of owners do not exert an influence on users and the other owners in our proposed scheme. As the key revocation mechanism, the master secret key is split into more partial secret keys that are distributed to users. Accordingly, the system only needs to re-split and re-distribute the key rather than re-building the index for updates of users. When making queries, not only are the content of queries and the master secret key concealed, but collusion between some users and the cloud server is resisted. The proposed scheme also supports an efficient result verification mechanism. The security and utility of our scheme were confirmed thru analysis and evaluation.

Defining attributes of boutique hotels: a systematic literature review

PurposeBoutique hotels reflect a nascent phenomenon in the literature and in the accommodation sector. As a result, they are void of governmental classification and regulation. Concurrently, they lack any form of operational definition. The purpose of this paper is to address these limitations by identifying the core attributes found to define boutique hotels.Design/methodology/approachTo fulfil the purpose of this paper, the authors conducted a systematic literature review on Web of Science. This resulted in an analysis of 33 peer-review articles published from 1994 to 2022.FindingsThe findings of this review revealed that boutique hotels are defined by eight core attributes; these are (1) multiple ownership structures, (2) situatedness in a historic premises, (3) strategic locations, (4) thematized internal décor, (5) experience design, (6) high levels of personalization, (7) novelty in service provisions and (8) niche marketing strategies.Practical implicationsFor policymakers, this paper may be used as a reference point to establish designated classification systems for boutique hotels. For practitioners, this paper may be used as a source of inspiration and benchmark to establish boutique hotels which align to the criteria highlighted in this paper. For scholars, this paper proposes an operational description of boutique hotels and novel areas for future research.Originality/valueThis paper represents one of the initial efforts undertaken by researchers to unify the literature on boutique hotels.

Adoption of Renewable Energy Systems in common properties of multi-owned buildings: Introduction of ‘Energy Entitlement’

Renewable Energy Systems (RES) adoption in Multi-Owned Buildings (MOBs) is inferior due to ownership disagreements and social disputes. The multiple ownership of the RES in common properties of MOBs develops energy and benefit allocation concerns among the apartment owners. Accordingly, there is a need for a postulation that encapsulates the energy ownership and land administration aspects, extendable for policy implications. This paper aims to position the ‘Energy Entitlement’ of apartment owners as a critical research concept to promote the adoption of RES in MOBs. For positioning the concept, we holistically scrutinise the factors influencing the adoption of RES in MOBs and the existing energy allocation frameworks proposed in the literature while emphasising the necessity of ‘Energy Entitlement’. We find that available literature predominantly focuses on the barriers and enablers to adopting RES in MOBs. However, the synergy between the ‘RES’ and ‘Land Administration’ is among the least focused. The research on the energy-spatial conundrum in MOBs is in its nascent stage, with debatable energy allocation principles proposed by a few studies. We conclude by highlighting the implication of ‘Energy Entitlement’ across industry, academia and policy regimes that calls for an equitable delineation of energy ownership integrated with land administration principles.
