Published: February 2019

After critically analyzing and comparing the thoughts of Islamic legal scholars on authority of unrestricted interest (maá¹£laá¸¥ah al-mursalah) and its competence in juristic inference, the author concludes that both can be evidence for reasoning. Moreover, in new problems in which religious texts have not dealt with. This paper concludes that Muhammadiyah as a renewal Islamic movement has a certain council for issuing fatwÄs, namely Mejelis Tarjih dan Tajdid (The Council of Tarjih and Tajdid). It considers unrestricted interest as one of the evidences in juristic inference and issuing fatwÄs. This appears from fatwÄs issued by the council which are based on al-IjtihÄd alistiá¹£lÄá¸¥Ä« or so called unrestricted interest, including fatwÄ on unregistered marriage, fatwa on divorce not through the court, rely on al-á¸¥isÄb al-falakÄ« for determining early hijri months, fatwÄ on smoking, and fatwÄ on charity of profession. This paper is using inductive approach and its primary sources are the principles Islamic jurisprudence books. In addition, its secondary sources are the compilation of Majelis Tarjihâ€™s fatwÄ, articles, journals, and all information on this topic. Furthermore, this article also considers the books on comparative school of Islamic jurisprudence.

Efficient Cipher-Only Attack of a Stream Cipher in RDHEI Based on Pixel Smoothness Estimation
Authors: Chen Yuyu , Li Zenghui , Liu Beibei , Zhang Jiacheng , Yin Bangxu , He Hongjie
Published: February 2019

Reversible data hiding in encrypted images (RDHEI) has recently emerged as an effective approach to protect the confidentiality of image content through encryption while assisting in the management of encrypted images by lossless hiding some additional data in encrypted images. In 2018, Khelifi proposed a cipher-only attack (COA) on the RDHEI methods where a bit-wise XOR encryption (also called as stream cipher) method was applied. In this work, we propose an efficiency COA method where the number of encrypted images can be effectively reduced for estimating the key stream with the same error rate. According to the given encrypted images, this work first estimates the smoothness probability of all pixel in the corresponding original images. And then, the weight coefficient of each pixel in the COA attack is assigned based on their estimated smoothness. The rationality of the proposed pixel smoothness estimation algorithm is discussed and analyzed from both theoretical and experimental aspects. Experimental results show that the error rate of the key stream estimated by the proposed COA method is less than 1/14 of that by the literature COA algorithm [10].
Addressing Irrelevant Influences with Epistemic Humility
Authors: Gurrola Joseph
Published: February 2019

Implicit bias is an irrelevant influence which is pervasive in rational deliberation as well as in doxastic deliberation, and the doxastic attitudes informed by implicit biases have potentially far-reaching negative consequences. However, unlike other irrelevant influences, implicit biases are less likely to be identified by epistemic agents as factors which affect the rationality of doxastic attitudes since their presence in epistemic agents is difficult to identify by asking epistemic agents to reflect on singular beliefs or doxastic attitudes. Rather, identifying implicit biases as irrelevant influences in doxastic deliberation often requires the evaluation of many beliefs or actions of an epistemic agent to determine whether a pattern of bias exists. Consequently, reactive approaches to addressing irrelevant influences in belief formation which ask agents to reflect on singular doxastic attitudes may be ill-suited to address irrelevant influences like implicit bias. In this paper, I offer a proactive solution for mitigating the negative effects of irrelevant influences like implicit bias, which requires that epistemic agents embrace epistemic humility in forming beliefs which they have good reason to think could be affected by irrelevant influences. In conjunction with reactive approaches to addressing irrelevant influences, epistemic humility about the extent to which epistemic agents’ doxastic attitudes are informed by implicit bias and similar irrelevant influences has the potential to form better and more reliable epistemic agents in the long term.

Penggunaan material bambu telah dikenal penggunaannya sejak jaman dahulu. Namun bambu juga dikenal memiliki beberapa kelemahan, diantaranya rentan terhadap serangan rayap dan jamur bila terkena air. Oleh karenanya diperlukan perlakuan khusus untuk memperpanjang usia penggunaan bambu bila hendak digunakan sebagai material konstruksi. Metode pengawetan dengan perebusan adalah salah satu metode baru yang diterapkan dilapangan untuk memenuhi pasokan bambu awet, selain metode Visual Soak Diffusion (VSD) yang cenderung memakan waktu yang lebih lama. Tujuan penelitian ini adalah untuk mengetahui sifat mekanik kuat-lentur bambu Petung dengan metode pengawetan perebusan. Hasil pengujian memperlihatkan peningkatan kuat-lentur bambu yang signifikan (dua puluh persen lebih kuat-lentur) setelah diawetkan dengan metode perebusan, meskipun kadar air dalam bambu meningkat yang berimbas pada potensi serangan jamur. Hal ini dapat diatasi dengan cara menambahkan bahan anti jamur pada larutan pengawetan. Metode pengawetan dengan perebusan ini mampu menjadi alternatif utama pengganti bahan pengawet kimia.
Power and Hierarchy among Finnish Kaale Roma
Authors: Stenroos Marko Tapani
Published: February 2019

Despite the vast research on Roma in Europe and beyond, little has been written about Roma agency from a perspective that focuses on manifold dynamics of power. Having worked for two years on the Finnish Roma Inclusion Project in a dual role as ethnographer and project worker has inspired me to rethink concepts of power and to create an alternative narrative of the experience of marginalized and discriminated Finnish Kaale Roma. Encouraged by the current paradigm shift in Romani Studies (which increasingly focuses on Roma agency instead of objectifying the population), this paper explores Kaale power dynamics as part of the social order and empirically demonstrates two parallel and antagonist systems of power exercised by Roma: one that stems from the population’s traditional cultural customs and the other from Pentecostal/charismatic Christianity, agrowing trend among the Finnish Kaale. The purpose of this article is to underline Roma agency within the frame of national Roma policy practices in Finland.
From Reflexivity to Collaboration
Authors: Silverman Carol
Published: February 2019

Recently scholars have begun to investigate who produces knowledge about Roma and with what agendas. I extend this inquiry to ask how reflexivity by a non-Romani ally and researcher contributes to analyzing the production and use of knowledge in Romani Studies. I examine various roles I have inhabited and forms of scholarship I have produced, both successful and unsuccessful, during my long involvement in Romani studies to reveal how and why I represented Roma, and what uses this scholarship served. Calling for a “reflexive turn” in Romani Studies, I note that while self-examination of knowledge production is useful for all researchers, for nonRoma it is mandatory because historically non-Roma have held more authority. Embracing “critical whiteness” theory, I examine my privileged roles and my attempts at collaborative advocacy. Tracing a historical trajectory of shifting subjectivities, I narrate several crises, such as balancing essentialism with advocacy, respectfully presenting Romani music, and combining diplomacy with activism to illustrate dilemmas of representation that I have faced and the responses I crafted. These issues all underline the responsibility that non-Romani allies have in accounting for their words and actions.
Nomadism in Research on Roma Education
Authors: Lauritzen Solvor Mjøberg
Published: February 2019

This paper analyzes to what degree and how educational research from a European context explains Roma disadvantage in education by referring to nomadism. Three thematic areas emerged from an analysis of 55 research papers. First, that Roma are closely associated with nomadism in the literature, creating an essentialist discourse. Second, that anti-nomadism contributes to explaining and justifying Roma exclusion. Third, that this impacts how the relationship between Roma and education is uderstood. Nomadism is seen as both incompatible with and in opposition to education, and nomadic learning is seen as a distinct learning style. All in all, the analysis shows that knowledge production on Roma and education has established a discourse where it is legitimate to use nomadism to explain Roma disadvantage ineducation. This understanding builds on an essentialist view of Romani culture, and it elaborates and sustains key tropes of antigypsyist discourses.
Power Hierarchies between the Researcher and Informants
Authors: Dunajeva Jekatyerina
Published: February 2019

Scholars have long been interested in researching Roma; a form of “top-down research,” where the  researcher analyzes, gathers data, and interviews the “objects” of the research, is still dominant in the field, although an increasing number of critics have been proposing ways of including Roma in knowledge production to shape the discourse about themselves. Exclusion of Roma in the process of research silences their voices and contributes to incomplete, flawed findings that often reinforce stereotypes. This paper takes a critical look at interactions and the power dynamics between the researcher and the informant(s) during research based on one in-depth case study: fieldwork conducted in a small town in Hungary in 2012–13. The presented research is one small step towards deconstructing knowledge production with a focus on research ethics and practice, rather than a large-scale paradigm change. This paper strives to transcend the scholarly field of Romani Studies specifically, and contribute to the broader literature on Social Science methodology, especially scholarship about interpretive methods and fieldwork.

The Class-to-Race Cascade
Authors: McCombs Jonathan
Published: February 2019

This paper explores neoliberal discourse as a racial discourse in relation to how Roma are conceived by academics and policymakers. I develop the concept of the class-to-race cascade as a way to describe the phenomenon, whereby the marginalization of racialized minorities is attributed entirely to their classposition. The cascade flows as follows: neoliberal policies slash benefits to low-income people, low-income people are disproportionately racially marginalized, thus neoliberal policies affect different racialized minorities, perpetuating racism. I trace the lineage of the class-to-race cascade to the concept of the“underclass” as it was developed in the U.S. particularly through the work of William Julius Wilson after the neoliberal turn. I then critique the work of Iván Szelényi and János Ladányi who adapted the “underclass” thesis to Roma, using the class-to-race cascade. Finally, I apply the concept to urban policy discourse inBudapest’s Eighth District, where a large Roma community has lived for nearly a century. I show in this paper that the class-torace cascade is a prominent discursive feature of both policy and academic concepts of Roma.
The Perception of Tone and Focus in Mandarin by Indonesian Learners: A Case Study
Authors: Hasanah Hana Nurul
Published: February 2019

In a tone language, the interface between tone, intonation, and focus will affect the pitch height and contour of tones. Previous perceptual studies revealed the potential conflicts in perceiving pitch variations at lexical and post-lexical levels that were experienced by either native listeners or listeners who speak Mandarin language as a second or foreign language. Rarely we find research in Indonesia that provides evidence for Mandarin language learners’ perceptual ability at a post-lexical level. This paper investigated how well learners with distinct first language (L1) background identify tones that are affected by the realization of focus and the presence and location of focus in distinct intonation types. Perceptual experiments were conducted towards two groups of listeners: Mandarin learners with Indonesian L1 and learners with a tone language L1 background (Hakka or Hokkien). Their identification accuracy (IA) rate in recognizing the tone type for the last syllable with a narrow focus was compared with their IA in identifying the location of the focus. In general, identifying tone type was easier than identifying focus position for both groups. However, the Mean from each group showed that learners with a tone language L1 were slightly better than the other group. Results exhibited more similarities between the two groups of the listener, which indicates that L1 background only has a mild effect on the perceptual ability of Indonesian learners of Mandarin as a foreign language.
Being “Loud”: Identities-in-Practice in a Figured World of Achievement
Authors: Caraballo Limarys
Published: February 2019

Discourses of achievement often overlook the interdependence of classroom contexts, students’ identities, and academic performance. This narrative analysis explores how high-achieving students of color construct identities-in-practice in a diverse urban middle school. By documenting explicit moments in which students construct identities-in-practice such as being “loud,” which are positioned as incompatible with “being smart,” I argue that high-achieving lower income students of color are disproportionately regulated by achievement discourses that position White middle-class norms as neutral. This article documents tensions between what it takes to achieve academically and students’ raced, classed, and gendered identities in order to reframe educational equity based on a theoretical framing of identities and academic achievement as interrelated and highly contextual.
Young Women Face Disadvantage to Enrollment in University STEM Coursework Regardless of Prior Achievement and Attitudes
Authors: Marsh Herbert W. , Van Zanden Brooke , Parker Philip D. , Guo Jiesi , Conigrave James , Seaton Marjorie
Published: February 2019

We evaluated STEM (science, technology, engineering, and mathematics) coursework selection by women and men (representative longitudinal sample, 10,370 Australians) in senior high school and university, controlling achievement and expectancy-value variables. A near-zero total effect of gender on high school STEM enrollment reflected pathways favoring boys through achievement and expectancy-value variables, but a counteracting direct effect of gender favoring girls. In contrast, subsequent university STEM enrollment favored boys. In both high school and university, enrollments favored girls in life sciences and boys in physical sciences, but at university there was a leaky pipeline in which girls who qualified to pursue physical sciences opted for non-STEM subjects. Qualitative analysis not only supported quantitative results but also highlighted alternative mechanisms of STEM engagement/disengagement, and mostly supported gender similarities rather than differences.
Dielectric and piezoelectric properties of porous lead-free 0.5Ba(Ca0.8Zr0.2)O3-0.5(Ba0.7Ca 0.3)TiO3 ceramics
Authors: Bowen Chris
Published: February 2019

Porous barium calcium zirconate titanate 0.5Ba(Ca0.8Zr0.2)O3-0.5(Ba0.7Ca0.3)TiO3 (BCZT) lead-free ferroelectric ceramics were fabricated via a burnt polymer spheres (BURPS) technique by introducing corn starch as the pore-forming agent. The effect of porosity on the microstructure, dielectric, and piezoelectric properties of the porous materials were investigated. An increase in porosity from 10 % to 25 % resulted in an increase in the hydrostatic charge coefficient (dh), which was 140 to 560 % higher than that of the dense BCZT material. An increase in porosity from 10 % to 25 % also lead to a decrease in relative permittivity that was 16.7% to 60.4% lower than the dense material. These two changes in properties provided a significant enhancement of the hydrostatic figure of merit (dh·gh) for the porous ceramic; for example the dh·gh of the 25 vol.% porous BCZT ceramic was 158 times more than the dense ceramic and demonstrates the potential of porous lead-free ferroelectrics for piezoelectric transducer devices. Reasons for the significant enhancement in piezoelectric performance of the porous ceramics are discussed.
Study on the cause and pathogenesis of Alzheimer's disease
Authors: sun zuodong
Published: February 2019

An enlightening viewpoint based on the theory of brain cell activation is to explore the pathogenesis and mechanism of sporadic Alzheimer's disease (AD) at molecular level by applying the principles of cell physics and biology. Its purpose is to coordinate and unify the existing theories of AD etiology and to solve the problems that have puzzled the research field of neurodegenerative diseases for a long time. Basic Contents: Excessive cations are transferred from extracellular to intracellular, and compete with potassium ions on the inner surface of the cell membrane. As a result, the action potential produced can not activate calcium channels normally, leading to abnormal apoptosis of brain cells. Amyloid plaques are the remains of abnormal apoptotic brain cells. Amyloid plaques are aggregated by van der Waals force and electrostatic attraction between amyloid plaques. The interstitium is amyloid protein. Brain cells consist of neurons, microglia and astrocytes in turn. Most of the spotted nuclei in the remains are cations. Applicable but not limited to neurodegenerative diseases such as Alzheimer's disease, physical means should be preferred to solve such diseases.
Use it or lose it : The influence of second order effects of practical components on storing energy harvested by pyroelectric effects
Authors: Bowen Chris
Published: February 2019

Harvesting energy using the pyroelectric effect has seen growth as a potential energy source for low power applications, such as self-powered and autonomous wireless sensor networks. The scavenged energy is generally at low power levels, from mW to less than μW. While the voltages generated by pyroelectrics can be appreciable, the electric currents can be low in the order of nano-amps. In the case of pyroelectric harvesting the frequency of operation can also be low, typically much lower than 1 Hz, due to the slow temperature oscillations and transients in systems of large thermal mass. The combination of low power levels and low frequency of operation means that methods of storing electrical energy generated by pyroelectrics and the influence of inherent second order losses is of importance to create efficient harvesting devices. This paper examines the second order characteristic effects of practical capacitors and diodes for storage. The stored energy decay characteristics for commercially available components are examined and the data is used to characterise the second order effects. Selected components are then used in a pyroelectric harvesting system to determine potential improvements by appropriate selection of components with low loss.
Anisotropy Factors and Electromechanical Coupling in Lead-Free 1–3-Type Composites
Authors: Bowen Chris
Published: February 2019

The effective electromechanical properties andanisotropy factors of novel lead-free 1–3-type compositesare studied to demonstrate their large piezoelectricanisotropy and considerable level of electromechanicalcoupling. The composites studied contain two single-crystal components and a polymer component. The firstpiezo-active component is a domain-engineered [001]-poled single crystal based on ferroelectric alkali niobates-tantalates, and this component is in the form of a system oflong rods that are parallel to the poling axis OX3. Thesecond single-crystal component is a system of spheroidalpiezoelectric Li2B4O7 inclusions aligned in a continuousand relatively large polymer matrix. The single-crystalrods are surrounded by a single crystal / polymer matrix,and the connectivity of the composite is 1–0–3. It is shownthat the conditions d * /| d * | 3 5, which indicates a large 33 31degree of anisotropy of the piezoelectric coefficients, and k* /|k* |35and k*/|k*|35,whichindicatealargeanisotropyof the electromechanical coupling factors, can be achievedsimultaneously in specific ranges of the component volumefractions and inclusion aspect ratios. Moreover, in thesame volume-fraction and aspect-ratio ranges, largeelectromechanical coupling factors (k* » k* » 0.8–0.9) are 33 talso achieved. In this context, the important role of the elastic properties of the continuous anisotropic matrix is discussed. The properties and anisotropy factors of the lead-free 1–3-type composites are compared to similar parameters of conventional lead-containing piezoelectric materials, and the advantages of the composite system studied are described.

Pyro-electrolytic water splitting for hydrogen generation
Authors: Bowen Chris
Published: February 2019

Water splitting by thermal cycling of a pyroelectric element that acts as an external charge source offers an alternative method to produce hydrogen from low-grade waste heat or natural temperature changes. In contrast to conventional energy harvesting, where the optimised load resistance is used to maximise the combination of current and voltage, for water splitting applications there is a need to optimise the system to achieve a sufficiently high potential difference for water electrolysis, whilst also maintaining a high current output. For the thermal harvesting system examined here, a high impedance 0.5 M KOH electrolyte with working electrodes connected to a rectified pyroelectric harvester produced the highest voltage of 2.34 V, which was sufficient for H2 generation. In addition to electrolyte concentration, the frequency of the temperature oscillations was examined and reducing the heating-cooling frequency led to a larger change in temperature to generate more pyroelectric charge and a higher potential difference for pyro-water splitting. Finally, in the absence of sacrificial reagents, cyclic production of H2 (0.654 μmol/h) was demonstrated for the optimised processing parameters of electrolyte and thermal cycling frequency using the external pyroelectric element as a charge source for water splitting.

Understanding the AC conductivity and permittivity of trapdoor chabazites for future development of next-generation gas sensors
Authors: Bowen Chris
Published: February 2019

Synthetic K+ chabazite (KCHA), Cs+ chabazite (CsCHA) and Zn2+ chabazite (ZnCHA) have been synthesized and investigated in order to relate the differences in their crystalline structures to their thermal stability, moisture content and frequency dependent alternating current (AC) conductivity, permittivity and phase angle at a range of temperatures. The materials are shown to exhibit the universal dielectric response, which is typical of materials consisting of both conductive and insulating regions. Due to the presence of porosity the three chabazites were hydrated significantly at room temperature and so the dehydrated state was achieved by heating the chabazites to high temperatures to ensure that all different energetic types of water were removed. Cation migration activation energies for KCHA (0.66 ± 0.10) eV, CsCHA (0.88 ± 0.01) eV and ZnCHA (0.90 ± 0.01) eV were determined during the cooling cycle from the fully dehydrated state to provide an accurate measurement the activation energies. Good thermal stability of the materials was observed up to 710 °C and below 200 °C the electrical properties can be strongly influenced by hydration level. Overall, it was determined that when either hydrated or dehydrated, KCHA had the highest conductivity and lowest cation migration activation energy of the three studied chabazites and thus has the most promising electrical properties for potential use as a gas sensing material in next-generation electrical- based gas sensors.
RELEVANSI PATEN DENGAN KEGIATAN AKADEMIS DI PERGURUAN TINGGI

Perguruan Tinggi (PT) adalah sebuah tempat terjadinya transfer ilmu pengetahuan dan pertukaran ide yang dinamis di antara para pihak yang terlibat di dalamnya. Transfer ilmu pengetahuan dan pertukaran ide tersebut terjadi melalui berbagai kegiatan tri dharma PT, yaitupengajaran, penelitian, dan pengabdian masyarakat. Semua hasil kegiatan pengajaran, penelitian, dan pengabdian masyarakat tersebut merupakan objek perlindungan berbagai hak kekayaan intelektual (HKI), seperti hak cipta, paten, desain industri, merek, desain tata letak sirkuit terpadu (DTLST), perlindungan varietas tanaman (PVT), dan rahasia dagang (RD) yang dapat menjadi milik sebuah PT tanpa bermaksud mengecilkan arti cabang-cabang HKI lainnya. Tulisan ini akan fokus menguraikan paten dan relevansinya dengan kegiatan akademis di PT.Paten adalah hak eksklusif yang diberikan oleh negara kepada penemu atas hasil invensinya di bidang teknologi. Karena paten hanya terbatas diberikan kepada invensi dalam bidang teknologi, beberapa PT yang hanya memiliki fakultas atau jurusan ilmu-ilmu sosial tentulah tidak dapat menghasilkan objek perlindungan hak paten. Paten menjadi HKI yang paling relevan bagi PT yang memang khusus menawarkan program pendidikan terkait teknologi. Sebagai contoh, Institut Teknologi Bandung dan Institut Pertanian Bogor adalah dua PT terdepan di Indonesia yang banyak menghasilkan invensi yang dilindungi paten.Kata Kunci : hak kekayaan intelektual
Top Indian wealth shares and inheritances 1966-1985
Authors: Kumar Rishabh
Published: February 2019

Between 1953 and 1985 India implemented various progressive taxes on personal wealth. I use estate tax returns to compute top wealth shares (top 1%, top 0.1% and top 0.01%) over 1966-1985; a period marked explicitly by a dirigiste policy environment. These new series suggest that wealth concentration in India reduced substantially during the 1970s. Although the decline affected the entire top 1%, the losses faced by the top 0.01% were especially large. Combined with identical trends in top income shares, it appears that the 1950-80 expropriations of India’s rich had similarities to institutional transitions and shocks faced by European elites in the early to mid twentieth century.

1‐3‐Type Composites Based on Ferroelectrics: Electromechanical Coupling, Figures of Merit, and Piezotechnical Energy‐Harvesting Applications
Authors: Bowen Chris
Published: February 2019

The physical and microgeometric factors that are able to improve the piezoelectric performance, anisotropy, and energy‐harvesting characteristics of modern 1‐3‐type composites based on ferroelectrics are discussed. The composite connectivity patterns of particular interest for this study include 1‐3‐0, 1‐0‐3, and 1‐2‐2. The active components of the studied composites are chosen from conventional perovskite‐type ferroelectric ceramics, lead‐free materials, or domain‐engineered single crystals, all of which exhibit particularly intriguing electromechanical properties. Examples of the large anisotropy of piezoelectric coefficients, electromechanical coupling factors, squared figures of merit, and large hydrostatic parameters of the three‐component 1‐3‐type composites are considered in the context of their piezotechnical applications. The applications of these materials include piezoelectric transducers, sensors, energy‐harvesting, and hydroacoustic devices.
