description: Solitons formed through the one-dimensional mass-kink mechanism on the edges of two-dimensional systems with non-trivial topology play an important role in the emergence of higher-order (HO) topological phases. In this connection, the existing work in time-reversal symmetric systems has focused on gapping the edge Dirac cones in the presence of particle-hole symmetry, which is not suited to the common spin-Chern insulators. Here, we address the emergence of edge solitons in spin-Chern number of $2$ insulators, in which the edge Dirac cones are gapped by perturbations preserving time-reversal symmetry but breaking spin-$U(1)$ symmetry. Through the mass-kink mechanism, we thus explain the appearance of pairwise corner modes and predict the emergence of extra charges around the corners. By tracing the evolution of the mass term along the edge, we demonstrate that the in-gap corner modes and the associated extra charges can be generated through the $S_z$-mixing spin-orbit coupling via the mass-kink mechanism. We thus provide strong evidence that an even spin-Chern-number insulator is an HO topological insulator with protected corner charges.

description: Abstract This research aims at examining the direct and indirect impacts of climatic changes as well as the effects of non-climatic factors on household food security in Malaysia. The study is based on primary data collected in the months of July – October, 2012 through a questionnaire survey on 460 low income households from East Coast Economic Region (ECER) of the country. The samples were selected from E-Kasih poor household database, based on cluster random sampling technique. The statistical estimation was done through two-stage formative path measurement model by using nonparametric bootstrap procedure under Smart PLS. This study finds that household food insecurity ECER – Malaysia is not only related to social and economic factors, but also statistically significantly linked to the direct and indirect impacts of climatic factors. The policy implications of the study suggest that design of food security programs must be integrated with climatic change adaptation programs. The government and other relevant agencies should jointly develop appropriate policies for poverty alleviation, household level food security, and adaptation with climatic changes in Malaysia.

description: Abstract Water scarcity is becoming a central issue in agricultural activities around the world. As agriculture is one of the major consumers of freshwater, more yield or output using same or less amount of water has become the global interest. Therefore water productivity (WP) is also considered as an indicator of agricultural productivity. Several research works have been conducted on WP values of different yields, tools and technologies to improve WP. Most of the studies on water productivity considered the crop productivity using limited water resource and searched for better technologies for improving crop water productivity. Researchers also concentrated on improving irrigation efficiency or water use efficiency at field level for irrigation through water management and for yielding more crops. But there is a research gap in assessing values of water productivity in aquatic ecosystems especially floodplain areas. A floodplain area remains dry and flooded in two different seasons. Thus, a combined valuation of aquatic resources and rice production in two different seasons are very important to measure the efficient usages of the lands. So, this study deals with how to measure annual aggregate water productivity for dry season and flood season in a floodplain beel area.

description: Excerpts from the report: Farm mortgages recorded by principal lender groups in the first quarter of 1961 averaged $10,990 in size, carried an average interest rate of 5.79 percent, and were written for an average term of 16.1 years. The average size of loan secured by farm real estate was nearly 10 percent larger than the average two years earlier. The average term was longer by 1.3 years, and the average interest rate was higher (0.38 percentage point) than in the first quarter of 1959. These findings are from tabulations and analysis of nearly 48,000 farm mortgages recorded in approximately 1,600 counties in the United States during the first quarter of 1961. Data for this biennial survey were obtained by the Farm Credit Administration through secretary-treasurers of Federal land bank associations, county recorders, and others. A sample of life insurance companies also was surveyed to obtain supplementary data on the mortgages recorded by them. Data on the mortgages recorded by the Farmers Home Administration (FHA) and production credit associations (PCA's)--interest rate, term, and size--are published for the first time in this series.

description: We employ a deep learning method to deduce the \textit{bulk} spacetime from \textit{boundary} optical conductivity. We apply the neural ordinary differential equation technique, tailored for continuous functions such as the metric, to the typical class of holographic condensed matter models featuring broken translations: linear-axion models. We successfully extract the bulk metric from the boundary holographic optical conductivity. Furthermore, as an example for real material, we use experimental optical conductivity of $\text{UPd}_2\text{Al}_3$, a representative of heavy fermion metals in strongly correlated electron systems, and construct the corresponding bulk metric. To our knowledge, our work is the first illustration of deep learning bulk spacetime from \textit{boundary} holographic or experimental conductivity data.

description: ABSTRACT Sustainable food security at household level is one of the emerging issues for all nations. There are several factors such as social, economic, political, demographic, natural, and livelihood strategies that causes to the vulnerability of the status of household food security. Therefore examining the vulnerability of these factors is essential to identify the reason and recognize the most vulnerable communities. This study is an attempt to study on the vulnerability of the factors of household food availability and its linkage with climatic changes in Malaysia. The study is based on primary data collected in the months of July – October, 2012 through a questionnaire survey on 460 low income households from East Coast Economic Region (ECER) in Malaysia. The samples were selected from E-Kasih poor household database, based on cluster random sampling technique. The study found that the vulnerability of the factors of household food availability has decreased statistically significantly over the last five years period in Malaysia for the factors of effectiveness of food distribution process, road and transportation facility for food distribution process, availability of expected food in the local market, sufficiency of expected food in the local market, and stability of food supply in market. The mean values of the current status of the factors of household food availability differ significantly at 1% significance level from the scenario of 5 years ago. However, most of the cases climatic issues were found less responsible for the changes of these factors. Though Malaysia is adversely affected by climatic change, the factors of food availability are not affected yet remarkably. This study suggests that the food security programs need to be integrated with climatic change adaptation programs to ensure more effective and sustainable household food security in future, especially among the poor and low income group. Moreover, a proper monitoring agency is required to ensure consistent supply of food in the rural and remote areas, especially at the time of natural calamity or off season.

description: Abstract Conservation of biological diversity is a pressing need and protected areas are the cornerstones for conserving remaining flora and fauna. However, forest dependent livelihood in countries like Bangladesh making this task very critical. In the case of the poor and forest-dependent livelihood in the Sundarbans area of Bangladesh, an eco-friendly ecotourism may provide an alternative livelihood, which may reduce the overexploitation from the valuable Sundarbans forest ecosystems. Furthermore, this initiative may also serve to aware people on the value of this unique ecosystems. Therefore, this study discusses the scope, benefits and challenges for developing sustainable ecotourism within the protected area. It focuses on the development of a potential site for sustainable ecotourism inside the Sundarbans Reserve Forest. Developing sustainable tourism spots inside the wildlife hub has a high demand among tourists and it is also necessary for the socio-economic development of the local community, moreover, the approach of community-based ecotourism (CBEM) is a suitable strategy for conservation of protected areas.

description: Abstract This research aims at analyzing the level of food security among some selected poor and low-income households in Malaysia. The study area is located in the East Coast Economic Region of the country. It uses primary data collected during the July-October months of 2012 and 460 sample families were chosen from the E-Kasih poor households database based on cluster random sampling technique. In this sample survey, households’ food security has been measured by the USAID-HFIA model. The findings of the study indicate that 52.8% of the households are food secure, that of 23.3% are mildly food insecure, 14.3% are moderately food insecure, and 9.6% are severely food insecure. The findings on the current situation of household food security among different economic groups is very important for the policy makers to achieve Vision 2020 and the targets of Malaysian National Plans regarding food security, socioeconomic development and poverty alleviation. In order to ensure food security in Malaysia, especial focuses are needed for those who are severely food insecured and those who are food insecured but marginally above the poverty line. Here the involvement of private sector and community based organizations are also important to combat the short run, seasonal, and event related risk of food insecurity as well as for the development of appropriate mitigation and adaptation options to ensure sustainable food security at household level in Malaysia.

description: Abstract This study is an attempt to assess the status of current level of value creation among the Government Linked Companies (GLCs) in Malaysia. This study collected primary data based on a set of questionnaire survey among 134 executives and managers of GLCs in Malaysia. The data were collected based on opinions of the ten factors of value creation practices by using the five-point Likert scale. The data were analysed using descriptive statistics. Further, the reliability of the data was tested using Cronbach’s alpha test, the validity of the data was tested by checking the normality test through skewness and kurtosis, and the consistency of the data was tested using factor analysis. On an average, 80.6% of the respondents agreed that they focus on these factors of value creation. Overall, the federal owned GLCs place more emphasis on certain elements of value creation than the state owned GLCs. Among the elements of value creation, the state owned GLCs emphasize the most on quality development and brand value creation, where the federal owned GLCs emphasized the most on reputation. The GLCs engaged in service sector emphasized the most on brand value and the GLCs engaged in manufacturing sector emphasized the most on customer satisfaction and quality development. This study suggest that GLCs in Malaysia improve the overall value creation by emphasizing on responsiveness, average return on investment, sales growth, profit growth and average return on sales.

description: Gelation behavior in mixtures has been investigated based on a gelator (BP8-A), containing three di-hydrazide units as the rigid core. It was demonstrated that BP8-A was soluble in many organic solvents, such as chloroform (CHL), benzene (Ben), toluene (Tol), and tetrahydrofuran (THF) but formed gels in alcohols, except methanol (MeOH) in which precipitate was observed. We developed a simple but effective method for preparation of BP8-A gel in different solvents at room temperature without heating-cooling process, that is, injection of certain amount of methanol (volume ratio between 8:2 and 7:3) into BP8-A solutions in CHL, Ben, Tol, and THF. Xerogels from MeOH/CHL, MeOH/Ben, MeOH/Tol, and MeOH/THF showed crystalline feature. The films from BP8-A xerogels in the mixtures are superhydrophobic with the contact angles (CAs) higher than 140°.

These models have played a key role in understanding the dynamics of plankton in the oceanic layer. Given the strong environmental and seasonal fluctuations that are present in the oceanic layer, we propose a stochastic model for which we are able to fully classify the longterm behavior of the dynamics. In order to achieve this we had to develop new analytical techniques, as the system does not satisfy the regular dissipativity conditions and the analysis is more subtle than in other population dynamics models.

description: ABSTRACT   Malaysia has seen a high rate of economic growth in past couple of decades hand in hand with an ever increasing size of population. As a consequence, the issue of sustainable waste management has become an important priority for policymakers and other stakeholders of the society. Although there are potentials to recycle up to 80 per cent of the total dry wastes collected, currently most of them are deposited into various landfill sites. Waste treatment facilities are also insufficient in the country. The government has introduced SWM Act 2007 along with other initiatives to improve the waste management scenario, but more needs to be done to be able to recycle and treat a major portion of the wastes. Based on studies on the state of Selangor in Malaysia, this paper this paper attempts to analyse the waste management scenario of Malaysia and the problems and prospects of waste recycling there. The paper will help the policy makers, waste management strategists, local administrators and researchers in the field to formulate sustainable policies and identify further areas of study in the relevant field.

description: Excerpts from the report: Alfalfa meal production in the U. S. generally has trended upward since its introduction as a new feed item in the early 1900's. In the beginning, meal was processed only from suncured alfalfa but, in 1910, the first dehydration system was developed with construction of a plant in Louisiana. Dehydrated alfalfa meal, however, did not advance to a commercial basis until the 1930's. In 1931, the first plant west of the Mississippi River, producing dehydrated meal on a commercial level, was located in Kansas. Through 1944-46, production totaled less than a million tons annually. But, in 1945-46, annual production increased sharply and has exceeded a million tons each year since. Alfalfa meal production has continued its upward trend in recent years and, in the current October-September feeding year, will probably exceed 1,600,000 tons for the first time. Basically, alfalfa meal can be described as a roughage feed ingredient which can be utilized in varying quantities by all classes of livestock and poultry. Its relatively high fiber content, however, limits the quantity that can be used in poultry rations. Alfalfa meal is marketed in a number of processed forms including meal, granules, pellets, and reground pellets.

description: In this proof-of-concept paper, we propose a specific kind of pedagogical use of ChatGPT - to help teachers practice their Socratic dialogue skills. We follow up on the previously published paper "ChatGPT and the frustrated Socrates" by re-examining ChatGPT's ability to engage in Socratic dialogue in the role of a physics student. While in late 2022 its ability to engage in such dialogue was poor, we see significant advancements in the chatbot's ability to respond to leading questions asked by a human teacher. We suggest that ChatGPT now has the potential to be used in teacher training to help pre- or in-service physics teachers hone their Socratic dialogue skills. In the paper and its supplemental material, we provide illustrative examples of Socratic dialogues with ChatGPT and present a report on a pilot activity involving pre-service physics and mathematics teachers conversing with it in a Socratic fashion.

description: Schule und Unterricht weisen paradoxe Grundstrukturen auf, in denen die pädagogischen Praxen von Lehrkräften fortwährend von verschiedenen Antinomien geprägt sind (Helsper, 2002, 2004, 2011). Es ist somit grundsätzlich davon auszugehen, dass professionelles Handeln in diesem kontingenten Feld des Unterrichts ebenso durch die Relation von Handeln und Widerfahren (Kamlah, 1973) wie von Zukunftsoffenheit und Ungewissheit mitbestimmt wird (vgl. ausf. Paseka, Keller-Schneider & Combe, 2018). Allerdings ist Unterricht ebenso durch spezifische Wirkungserwartungen begründet und das Unterrichten auf intendierte Wirkungen – und somit auf Kontinuität – hin zentriert. Vorliegender Beitrag thematisiert solche Paradoxien, Kontingenzphänomene und Ungewissheiten im Unterricht als Herausforderung für (sport-)pädagogisches Handeln. Dies betrifft unmittelbar den Unterricht, mittelbar aber auch die Lehrer*innenbildung. Im Folgenden versuchen wir aufzuzeigen, dass gerade von spezifischen Ungewissheiten der Praxis abstrahierte wissenschaftliche Diskurse und Befunde wichtige Orientierungen für das professionelle Handeln ermöglichen und daher mit Recht einen wesentlichen Schwerpunkt der universitären Lehre bilden: Sinnvolle und notwendige Bezüge auf Praxis im Studium werden hierdurch nicht relativiert, sondern in einen reflexiv-forschenden Erfahrungsbezug gebracht, um ein fundiertes und begründbares Handeln als Lehrende im Unterricht zu ermöglichen. Auf Basis dieser Prämissen werden Konsequenzen für die professionelle Entwicklung von (Sport-) Lehrkräften ausgelotet, hinsichtlich der je spezifischen Relevanz von Theorie und Praxis sowie Forschen und Lernen in einen gemeinsamen Rahmen gebracht und diskutiert.

description: In der sinnverstehenden Unterrichtsforschung wird die Frage nach Kontinuität und Kontingenz im Unterricht mit unterschiedlichen sozialtheoretischen Begriffen schon lange diskutiert. Die Frage praxistheoretisch zu wenden, heißt, das für Praktiken zentrale Moment der Wiederholung theoretisch und empirisch in den Blick zu nehmen. In dem Beitrag wird hierfür das noch wenig beachtete Moment der Normativität von Praktiken theoretisch und an empirischen Beispielen ausbuchstabiert. In den Blick kommen so die teleo-affektiven Strukturen von Praktiken (Schatzki) und die Frage nach der Rekonstruktion von Anschlusshandlungen in der normativ-affektiven Dimension von Praktiken.

description: The relationship between human rights and human development was formally introduced in debates by UNDP in 2000 in its Human Development Report. The report discussed the two-way relationship between the two concepts and stressed that human rights and human development positively affect each other. This paper underlines that if it is common for human rights to positively affect human development, the direction of causality can be reversed in times of crisis as in the case of covid-19. Contrary to the exiting literature that generally breaks down government interventions into pharmaceutical and non-pharmaceutical interventions, this paper goes beyond this classification to distinguish basic protective measures from human rights limitng measures. The paper demonstrates that promoting human rights favours the progression of the pandemic, negatively affecting human development while reducing human rights is a key instrument to limit the number of deaths during pandemic. This is the rationale of the worldwide use of human-rights-limiting measures to control the progression of the pandemic and secure human development. The worldwide use of human-rights-limiting measures is therefore regarded as a tunnel which helps to curb down the number of deaths in pandemic times.

description: The genus-1 Kadomtsev–Petviashvili (KP)-Whitham system is derived for both variants of the KP equation; namely the KPI and KPII equations. The basic properties of the KP-Whitham system, including symmetries, exact reductions and its possible complete integrability, together with the appropriate generalization of the one-dimensional Riemann problem for the Korteweg–de Vries equation are discussed. Finally, the KP-Whitham system is used to study the linear stability properties of the genus-1 solutions of the KPI and KPII equations; it is shown that all genus-1 solutions of KPI are linearly unstable, while all genus-1 solutions of KPII are linearly stable within the context of Whitham theory.

description: Abstract Efficient Market Hypothesis (EMH) is founded on the theory of expected rationality but the theory of behavioural finance concludes that stock market investors are quasi-rational. Therefore, under the capitalistic system, the efficient markets have already failed to protect the rights of investors that have led to chronic capital market crashes and failure to achieve efficiency, justice, fairness, accountability, fair distribution of benefits, and a rational behaviour among investors. However, recently, Islamic financial institutions and markets have been emerging, which stand on the Shariah provision – the guided way to behave rationally or guided rationality. Based on the empirical experiences and evidences of both market systems, this paper discusses and compares the performances of the markets under the theoretical arguments of “rationality”, “quasi-rationality”, and “guided rationality”. This paper suggests that capital market based on guided rationality under the Islamic System can be a better alternative over the conventional market system.
An Estimation of Market Size for Microfinance: Study on the Urban Microentrepreneurs in Selangor, Malaysia

description: Abstract Malaysia is a fast growing developing country where majority of the people are Muslim. Due to the religious bindings, Muslim prefers Shariah compliant Islamic credits instead of conventional interest based credits. At the same time, non-Muslims can also consider Shariah compliant Islamic credit because it is considered as the ethical credit. However, still many microentrepreneurs are not receiving the Shariah compliant Islamic microfinance products because they have negative perceptions about the credit and interest (riba). Therefore, this study aims to assess the demand for microfinance among the microentrepreneurs in the State of Selangor, Malaysia and thus, determine the potential market size. Data of the study were collected based on a questionnaire survey from 550 microentrepreneurs from the urban areas of Selangor. It was found that only 12.2 per cent of them received microfinance from various microfinance institutions and banks. However, the study found that still there is potential for microfinance borrowing with around 55,000-128,000 microenterprises in Selangor, Malaysia. Therefore, Islamic microfinance institutions should try to expand their market size by promoting these potential microfinance borrowers among the existing microentrepreneurs.
Islamic and Social Entrepreneurships for Social Justice: A Policy and Structural Framework for Social Enterprise Economics

description: Abstract Entrepreneurship is indispensable for progress of human civilization and effectively exploring and exploiting existing and potential resources for wellbeing of humanity. Modern economics operates basically through two major modes of entrepreneurships: the market/private sector economics relying on commercial entrepreneurships (self-interest- centric) and the state/public sector economics relying on state entrepreneurships (public-wellbeing-centric). However, both have, individually and jointly, failed to ensure economics’ fundamental goal of wellbeing for human societies. In response, a community wellbeing-centric social enterprise economics (third sector), which features cooperatives and not-for-profit social enterprises in the name of foundations, trusts/awqāf, social businesses, and similar undertakings, has emerged as a make-up strategy to meet the minimum unmet requirements for social wellbeing. However, there is a strongly felt belief that this community wellbeing-centric social enterprise economics needs to be broadened and mainstreamed in order to include entirely charitable institutions, predominantly not-for-profit operations, and predominantly for-profit businesses but blended with provision of social welfare programs like corporate social responsibility, etc., for its emancipation as a major economic system to be able to play a leading role for ensuring desirable economic growth and development. Islamic entrepreneurship, which is basically a community-centric mode of business initiative, is closely related to social entrepreneurship. It is an antidote to the problem of intolerable economic and social dualism and a natural strategy against all forms of capitalist exploitation to control world resources, like, in the past, through European colonialism, and now, through American-led state terrorism. It is the natural guard against economic inequity, wealth concentration, and social divides. Based on its potential and using examples from Bangladesh and Malaysia, we argue that the Islamic style social entrepreneurship, which is operationally a profession for a mission, is intellectually and operationally superior and more efficient for effectively widening and mainstreaming community-centric social enterprise economics to ensure development with equity and social justice. The paper aims to put forward social enterprise economics (third sector) for dialogue and research in the context of effective functioning of modern economies ensuring community wellbeing.
PERFORMANCE OF ISLAMIC MICROCREDIT IN PERSPECTIVE OF MAQASID AL-SHARIAH: CASE STUDY ON AMANAH IKHTIAR MALAYSIA

description: Abstract Many studies have evaluated the role of microcredit programs using the conventional assessment approach. However, the conventional system of socioeconomic role assessment cannot evaluate the performance of Islamic microcredit in terms of achieving the objectives of Shariah for the Islamic microcredit model. Therefore, this study examines the role of Islamic microcredit based on the achievement of Maqasid Al-Shariah. It uses primary data that were collected through a questionnaire survey distributed among 393 microcredit borrowers from Amanah Ikhtiar Malaysia (AIM). The survey was conducted from July 2013 to December 2013 in the State of Sabah and in Peninsular Malaysia. This research also analyzes the socioeconomic roles and the achievement of microcredit and microenterprise from the perspective of the five principles of Al-daruriyyat from Maqasid Al-Shariah. Results indicate that the microcredit program of AIM has a positive and enhancing effect on the livelihood of clients. This effect is reflected in the assessment of their well-being, especially in the context of Maqasid Al-Shariah.

description: Excerpts from the report: Increased costs of constructing new cotton gins or modifying existing ones to keep them abreast of the rapid technological advances in equipment have made ginners acutely aware of the need to operate efficiently. Ginner groups have requested the development of information on operating costs for various types of gins as a basis for evaluating their relative operating efficiency and indicating potential reductions in costs. The purpose of this study was to determine: (1) power costs for specified types of gins and factors affecting these costs, and (2) consumption of fuel for driers and its cost per bale ginned. Data were obtained during the 1960-61 season from 90 all-electric gins located in Arkansas and Missouri. Plants ranged in size from 3/80-saw gin stands to 5/90-saw stands. Data on quantity and cost of electricity used were collected from all gins, and data on quantity and cost of fuel for driers were collected from 49 of these gins

description: Software Defined Networking (SDN) is driving transformations in Research and Education (R&E) networks, enabling innovations in network research, enhancing network performance, and providing security through a policy-driven network management framework. The Holland Computing Center (HCC) at the University of Nebraska-Lincoln (UNL) supports scientists studying large datasets, and has identified a need for flexibility in network management and security, particularly with respect to identifying data flows. This problem is addressed through the deployment of a production SDN with a focus on integrating network resource management for large-scale GridFTP data transfers. We propose SNAG (SDN-managed Network Architecture for GridFTP transfers), an architecture that enables the SDN-based network management of GridFTP file transfers for large-scale science datasets. We also show how SNAG can efficiently and securely identify science dataset transfers from projects such as Compact Muon Solenoid (CMS) and Laser Interferometer Gravitational-Wave Observatory (LIGO). We focus on exposing an Application Program Interface (API) between the trusted GridFTP process and the network layer allowing the network to track flows via application metadata.
