SOCIO-ECONOMIC FACTORS AND CROP PRODUCTION EFFICIENCY IN CHINA AND ETHIOPIA: A REVIEW

The main challenge of agriculture is to ensure food security in line with yield increases and minimize environmental costs due to complex interactions between social, economic, and ecological factors. Here we review to identify the impacts of socio-economic factors on crop production efficiency between China and Ethiopia. To set the economic reform and improve the grain yields in rural China, a series of policies on land reforms from communal systems to tax cancelation and subsidies have been implemented. Similar to China, Ethiopia has also experienced different types of land reform from landlord and peasant structure to land as the common property of nations, nationalities, and peoples of Ethiopia. The Gross Domestic Products per capita trends which represent the mean standard of leaving of residents in a country show almost similar growth in the 1980s while later significant variation was achieved between the two countries. It is suggested that to meet food security and increase agricultural efficiency in Ethiopia better infrastructure development that meets socio-economic demands should be prioritized while in China policies to reduce fertilizer inputs are highly recommended to minimize the environmental costs due to high agricultural inputs for sustainable agriculture growth.

A Cross-laboratory Comparison Study of Titan Haze Analogs: Surface Energy

In Titan’s nitrogen-methane atmosphere, photochemistry leads to the production of complex organic particles, forming Titan’s thick haze layers. Laboratory-produced aerosol analogs, or “tholins,” are produced in a number of laboratories; however, most previous studies have investigated analogs produced by only one laboratory rather than a systematic, comparative analysis. In this study, we performed a comparative study of an important material property, the surface energy, of seven tholin samples produced in three independent laboratories under a broad range of experimental conditions, and we explored their commonalities and differences. All seven tholin samples are found to have high surface energies and are therefore highly cohesive. Thus, if the surface sediments on Titan are similar to tholins, future missions such as Dragonfly will likely encounter sticky sediments. We also identified a commonality between all the tholin samples: a high dispersive (nonpolar) surface energy component of at least 30 mJ m−2. This common property could be shared by the actual haze particles on Titan as well. Given that the most abundant species interacting with the haze on Titan (methane, ethane, and nitrogen) are nonpolar in nature, the dispersive surface energy component of the haze particles could be a determinant factor in condensate−haze and haze−lake liquid interactions on Titan. With this common trait of tholin samples, we confirmed the findings of a previous study by Yu et al. that haze particles are likely good cloud condensation nuclei for methane and ethane clouds and would likely be completely wetted by the hydrocarbon lakes on Titan.

High-Capacity Robust Behavioral Steganography Method Based on Timestamp Modulation across Social Internet of Things

Social Internet of Things (SIoT) is an emerging field that combines IoT and Internet, which can provide many novel and convenient application scenarios but still faces challenges in data privacy protection. In this paper, we propose a robust behavioral steganography method with high embedding capacity across social networks based on timestamp modulation. Firstly, the IoT devices on the sending end modulate the secret message to be embedded into a timestamp by using the common property on social networks. Secondly, the accounts of multiple social networks are used as the vertices, and the timestamp mapping relationship generated by the interaction behaviors between them is used as the edges to construct a directed secret message graph across social networks. Then, the frequency of interaction behaviors generated by users of mainstream social networks is analyzed; the corresponding timestamps and social networks are used to implement interaction behaviors based on the secret message graph and the frequency of interaction behaviors. Next, we analyze the frequency of interaction behaviors generated by users in mainstream social networks, implement the interaction behaviors according to the secret message graph and the frequency of interaction behaviors in the corresponding timestamps and social networks, and combine the redundant mapping control to complete the embedding of secret message. Finally, the receiver constructs the timestamp mapping relationship through the shared account, key, and other parameters to achieve the extraction of secret message. The algorithm is robust and does not have the problem that existing multimedia-based steganography methods are difficult to extract the embedded messages completely. Compared with existing graph theory-based social network steganography methods, using timestamps and behaviors frequencies to hide message in multiple social networks increases the cost of detecting covert communication and improves concealment of steganography. At the same time, the algorithm uses a directed secret message graph to increase the number of bits carried by each behavior and improves the embedding capacity. A large number of tests have been conducted on mainstream social networks such as Facebook, Twitter, and Weibo. The results show that the proposed method successfully distributes secret message to multiple social networks and achieves complete extraction of embedded message at the receiving end. The embedding capacity is increased by 1.98–4.89 times compared with the existing methods SSN, NGTASS, and SGSIR.

ISSUES FACED BY TENANTS IN HIGH-RISE STRATA RESIDENTIAL: CASE STUDY OF KLANG VALLEY

Recently, demand for high-rise residential has increased every year and shifted residential development patterns from vertical to horizontal development. Living in high-rise residential will require residents to share common facilities and resources. For that, a management body is known as Management Corporation (MC) or Joint Management Body (JMB) is established. This management body is responsible to collect the service charge from residents, as well as managing and maintaining the buildings and common property. However, a review of the literature has found out gaps between the MC responsibility and residents’ satisfaction. Driven by study objectives, this study focuses on exploring issues faced by the tenants living in the selected high-rise strata housing. Through a questionnaire survey, responses are randomly collected and analysed. A descriptive table, Relative Importance Index (RII) and correlation test are used in the analysis to provide findings for the study.

Sailing and insight reproduction of Geo-Socio-Cultural unity of Nusantara/Indonesia Maritime: A study focus of Maritime Anthropology

This paper aims to explain how Indonesia was conceptualized as the Indonesian Maritime Continent. From a geo-social perspective, maritime culture can be viewed in, three major dimensions. First, Indonesia is one of the largest archipelagic countries in the world with all the geographical potential, invaluable marine, and maritime resources; second, the potential for socio-cultural, socio-demographic, socio-economic, and long maritime cultural history within the framework of the unity of the Republic of Indonesia; and third, the existence of academic core and the maritime vision of Unhas, the idea of the Indonesian Maritime Continental Development which was launched by the government in 1995/1996, and the vision of maritime national development by President Joko Widodo marked the role of academics and governments in the dynamic process of development to the phase of maritime civilization in the future. In the context of developing maritime ethnographic studies and anthropological contributions to the development of maritime civilization in the future, ideas and academic commitment are needed to make the Indonesian Archipelagic State a large and unique area of maritime socio-cultural research development in the world and Southeast Asia in particular. Thus, interdisciplinary, transdisciplinary, comparative, and multidisciplinary research is needed to carry out broadly and intensively. For this reason, through my inauguration speech for Professor of Anthropology in Hasanuddin University, I introduced a focus of maritime anthropology studies on sailing experiences and the reproduction of Nusantara/Indonesian maritime geo-socio-cultural insights. Through the application of the concept of experience and reproduction of maritime geo-socio-cultural insights which were developed from the concept of maritime ethos disposition theory of reproduction from A.H.J. Prins as a mode of description and analysis, I found the categories of maritime cultural insights and attitudes of Indonesian sailors. They understand most of the territorial waters of the Nusantara (archipelago) and the resources within as common property, a space for interaction between groups of sailors who are diverse in their maritime ethnicity and culture, which in turn strengthens awareness and recognition of the unity of the homeland, culture, and nation that is Bhinneka Tunggal Ika (unity in diversity).

QUALIFICATION OF CONTESTED FAMILY LEGAL ACTIONS IN THE BANKRUPTCY CASE OF A CITIZEN

Ransactions and fulfillment of obligations and obligations arising in accordance with family law arethe subject of judicial challenge at the request of a financial manager acting in the interests of creditors inthe bankruptcy of a citizen. Science and the law do not consider the grounds for the invalidity of actions forthe execution of transactions. The family-legal actions of a debtor-citizen based on an agreement between spouses, parents and judicial acts on the division of common property and the recovery of alimony are subjectto challenge on the grounds provided for by the norms of the Civil Code of the law and the bankruptcy lawon the invalidity of transactions only for the convenience of law enforcement. The actions of spouses andparents to dispose of their property rights and obligations arising from family legislation are either familylaw contracts (agreements) or actions to fulfill the obligations provided for by the Family Code. The correctqualification of the debtor’s family legal actions determines the quality of law-making, understanding of theactual meaning of legal norms and the exact fulfillment of their prescriptions.

CONSEQUENCES OF LOSS OF COMMON PROPERTY RESOURCES IN THE SELECTED BLOCK, DINDIGUL DISTRICT OF TAMILNADU

Common property land resources include grazing ground, community pasture, village forests and woodlots, and village sites, on which the villagers have legal usufructuary rights; these land resources also include all another land formally held by the panchayat or a community of the villages (NSS 54th round). For a collection of data of common land resources de jure and e facto approaches were considered. Forest land resources which are under the jurisdiction of the forest department was also considered as poor dependent rural communities are directly or indirectly dependent on the forest for livelihoods. From the report of NSS 54th round, it is observed that 15% of India’s total geographical area substantially forms a part of common land resources. Consequences of loss of common property resources and depletion of common property resources resulted largely because there was no private cost for using these resources. Privatization of common property resources in the arid zone has invariably meant the conversion of common property resources land into cropland.

Willingness of the owners in the integrated development to establish the subsidiary management corporation

PurposeThe increasing number of strata property in Malaysia promotes the different usages of development under the integrated development, which comprise the different usages of owner groups. These owner groups may not enjoy all the common properties in the integrated development. Therefore, the purpose of this research is to identify the important to designate the limited common property for the owners who have the exclusive benefit on it. However, the establishment of the subsidiary management corporation and limited common property is less popular in Malaysia.Design/methodology/approachHence, research should be carried out to identify the importance of the establishment of the subsidiary management corporation and enhancement for the establishment of subsidiary management corporation to increase the willingness of the owner to establish the subsidiary management corporation. Collective Action Theory likewise assists to increase the willingness of the owner in the establishment of the subsidiary management corporation. A sum of 100 owners in the integrated development and 187 stratified property professionals are the respondents in this research, by applying the random sampling method.FindingsResults indicate the problems that occur in the integrated development is the complexity management in integrated development, followed by the usages of the common property. Therefore, Collective Action Theory could ensure the effectiveness of the establishment of the subsidiary management corporation in the aspect of social rights, resources, governance groups and participants.Originality/valueThis paper provided an overview of the management circumstance in the integrated development of Malaysia and discussed some effective enhancements to promote the sustainable formation of the subsidiary management corporation or two-tier management corporations.

The Autobiography in Paul Claudel’s MaConversion

The article deals with the autobiography of Paul Claudel in his essay Ma Conversion written in 1913 at the request of readers. The readers believe that his biography no longer belongs to him, so the experience of his conversion should be of common property. It reveals his confessional retrospective traits and self-awareness in biographical literary works. Different types of confession, features of preaching, self-expression and autobiography are interwoven in the essay. The language of the essay is poetic and polysemantic. Distance is manifested in many ways in Claudels works, from the explicit biographical author - moi, Paul to the literary author - le pote. The writer begins in a confessional, indecisive manner, but as he becomes more professional, he resorts to the biographical author less willingly, more often remaining on the sidelines as a literary author. There is less open reflection in the collection of works Conversations (1926-1937), so the poet discusses reality, but he does not describe his feelings and actions as he did when he was younger. Claudel's autobiography combines the sacred and the secular, while the intimate and the public act as a preparatory stage to a multi-volume exegetic novel.

Collective action components of low-cost housing: an empirical analysis using Ostrom's SES framework

PurposeTo date, low-cost housing held under the common-property regime is faced with various collective action or management issues in relation to common facilities. Understanding and unpacking key collective action components in a multi-dimensional and systematic fashion that help explain the status quo of the complex low-cost housing management is crucial, particularly in identifying potential factors contributing to the suboptimal self-governing outcome. Therefore, the purpose of this paper is to investigate the collective action of low-cost housing in Malaysia using Ostrom's institutional analysis development and social-ecological system framework (IAD-SES framework) as a theoretical framework.Design/methodology/approachFirst, a mixed-method research design was adopted where issues relating to the management of common properties of low-cost housing were identified in the Malaysian context. Second, the components of Ostrom's IAD framework relevant to collective action were identified. Third, after interviewing six experts in the housing industry via semi-structured interviews, two more components (historical development/adaptability to new environment and ethnicity) were added to the questionnaire survey. From here, 633 respondents who lived in four low-cost housings in Kuala Lumpur from 1,598 households were surveyed in 2012. We then merged the IAD framework with the SES framework. Factor analysis and Cronbach's alpha analysis were conducted to uncover the underlying variables and the social ecological clusters that they belonged.FindingsWith average Cronbach's alpha of 0.83, the seven key SES components identified are able to cumulatively explain 71% variance of local collective action components. Based on the cumulative percentage explained, the top five key SES components are as follows: context (social, economic and political settings); ethnicity; outcome; resource system; and users characteristics.Originality/valueThis study identifies key components related to the collective action issues of low-cost housing management, where two additional components were also suggested to be added to the SES framework. Apart from the theoretical contribution, the study, serving as insights and potential solutions, is also of practical significance to the existing management practices of low-cost housing in Malaysia where policymakers and management corporations may prioritize primary SES components, helping them govern common properties more efficiently.
