Consumer rights in halal products: a study based on legal and Syariah perspectives
Authors: Ab Halim M.A. , Mohd Salleh M.M.
Published: February 2020

Halal business is not confined to Muslim community only. Lately, halal food, cosmetics,
pharmaceuticals and Islamic financing services have gained much attention globally.
Businesses around the world are looking to tap this burgeoning market. Within the Islamic
global community of 1.8 billion, there exist many markets which have not been tapped
and discovered from both cultural and business perspectives. However, there are a lot of
abuses recently relating to halal in term of the logo, especially when it comes to foods and
products. The questions are whether Muslims’ rights are fully protected under halal
statutes and what is the rights conferred by law if they are not complying with the
regulation? for example, a question about the origins of foods or products ingredients and
whether or not they are complying with an Islamic requirement, and if it is not, what is the
best mechanism to overcome this issue in order to protect the consumer. This paper will
study on the rights of the consumer in halal products by referring to the legal statutes and
also looking at the Quranic verses and Hadith to find out whether the right is stipulated in
the statutes and Syara’. The finding of this paper shows that the rights of the consumer has
been provided impliedly in legal statutes and also in the Quran and Hadith. This paper
made some suggestions to ensure the rights of the consumer will be fully protected by
laws specifically in relation to halal products and try to harmonize the rights as
implemented in Al-Quran and Hadith into the Malaysian Laws.

Published: February 2020

Time correlated single photon counter was design for measuring fluorescence lifetime of emitting materials. It was designed for photonics basic research and science that is usually done in a laboratory. Furthermore, time correlated single photon counter can be used to measure simple and more practical optical properties of materials, such as refractive index. However, since the system was not designed for this practical application, a simple setup modification and calculation is required. In this work, time correlated single photon counter is utilized to measure the refractive index of sodium chloride solutions. The measurement was done using simple time of flight calculation of each pulse of picosecond pulsed laser. Our measurement was done on different concentrations of sodium chloride that have different refractive indices. It was found that the measurement technique and calculation was able to produce consistent quantitative calculation of refractive indices.

Authors: Djudin Tomo , Grapragasem Selvaraj
Published: February 2020

Analogy is considered a helpful way to help students visualize abstract concepts and assimilate new knowledge to an existing structure of cognitive. This study examines the effectiveness of the teaching with pictorial analogy models on students achievement and its retention of Direct Current lesson. A quasi-experimental method with one group pretest and (immediate and delayed) posttest design was employed in this study. The subjects consisted of 35 twelfth-grade students of public senior school in Pontianak City enrolled in the first semester of academic year 2017/2018; they were determined by using intact group random sampling technique. The student participants received instructions of the three pictorial analogy models. A parallel pretest-posttest of achievement test consisted of 10 items of factual knowledge, 10 items of conceptual knowledge, and 3 items of procedural knowledge. The operationalization of the pictorial analogies in this study referred to Glynns syntaxes. Data analysis found that: (1) the increasing of factual knowledge is 30.2 % in immediate posttest and 21.6 % in delayed posttest; (2)the students have promoted a significant conceptual change ( = 54.28, p < 0.05); and (3) there is a significant difference between the immediate posttest and pretest in terms of procedural knowledge (t = 4.02; p < 0.05) with the ES index is 4.78. It is concluded that the use of pictorial analogy models is effective (in high category) to increase students achievement of Direct Current lesson and the emergence of their retention is significant partially and simultaneously. In using pictorial analogies, teachers are encouraged to consider many similar features with the target concepts.
Quantum Propagator Derivation for the Ring of Four Harmonically Coupled Oscillators
Authors: Gallo James Mendoza , Butanas Jr. Bienvenido Masirin
Published: February 2020

The ring model of the coupled oscillator has enormously studied from the perspective of quantum mechanics. The research efforts on this system contribute to fully grasp the concepts of energy transport, dissipation, among others, in mesoscopic and condensed matter systems. In this research, the dynamics of the quantum propagator for the ring of oscillators was analyzed anew. White noise analysis was applied to derive the quantum mechanical propagator for a ring of four harmonically coupled oscillators. The process was done after performing four successive coordinate transformations obtaining four separated Lagrangian of a one-dimensional harmonic oscillator. Then, the individual propagator was evaluated via white noise path integration where the full propagator is expressed as the product of the individual propagators. In particular, the frequencies of the first two propagators correspond to degenerate normal mode frequencies, while the other two correspond to non-degenerate normal mode frequencies. The full propagator was expressed in its symmetric form to extract the energy spectrum and the wave function.

Educational Leadership Effectiveness. Is it a Matter of a Leader’s Characteristics, Behaviors, or Leadership Style?
Authors: Dimopoulos Andreas
Published: February 2020

Leadership in education has been examined in depth until nowadays regarding among others the most common models of leadership, the personal characteristics and profile of charismatic leaders, the principal leadership style and behavior. Notwithstanding, to the best of our knowledge so far, there is space for additional examination as far as for educational leadership effectiveness regarding these factors. This study aims to investigate the outcomes of educational leadership considering the most important components of leadership which are the leader characteristics’, behaviors’ and the most common exercised styles. Furthermore, a purpose of this study is to explore interconnections and correlations among leader characteristics’, behaviors, leadership styles and effectiveness. According to literature review, there is no clear answer in the question of which one component among leadership styles’, personal characteristics’ and behaviors’ is more significant and contribute more to leadership effectiveness. Research has shown that all these elements are fundamental and are considered all important for educational effectiveness. It is also argued that there is a strong interconnection between them as individual parts in an integrated system, which each one separately has its relative influence in educational leadership effectiveness. Also, there is a broad tendency for agreement according to which educational leadership effectiveness depends on many other factors apart from characteristics’, styles and behaviors’, such as timing, special conditions, legislation, personnel qualifications, expected outcomes’ importance, facilities and many others. Apart from these independent factors it is worth to mention that different leadership styles have different positive or negative outcomes to different stake holders. Therefore, it is hard to isolate and to define which of those components are more significant for leadership effectiveness.

BÖLGESEL TİCARET ANLAŞMALARI(BTA)’NIN GELİŞİMİ VE DERİN TİCARET ANLAŞMALARI: TÜRKİYE’NİN SERBEST TİCARET ANLAŞMALARI (STA) AÇISINDAN BİR ANALİZ
Authors: Hekim Yılmaz Derya
Published: February 2020

Tüm Dünya’da Bölgesel Ticaret Anlaşmaları(BTA)’nın sayısı özellikle 1980’lerden sonra artış göstermiştir. Ancak son yıllarda bu artış ivmelenmiştir. Küresel ticaretin yapısının değişmesi, küresel ticaretteki aktörlerin farklılaşması, yeni sorunların ortaya çıkması ve de en önemlisi Dünya Ticaret Örgütü(DTÖ)’nün bu sorunların çözümünde yetersiz kalması ülkeleri ticaret anlaşmaları yapmaya sevk etmiştir. Son dönemde yapılan anlaşmaların içeriği de yeni konuların gündeme gelmesiyle değişmiştir. Daha fazla düzenlemenin hükme bağlandığı daha fazla alanı kapsayan bu anlaşmalar Derin Ticaret Anlaşmaları olarak anılmaktadır. Türkiye’de son dönemde daha fazla BTA yapmaktadır. Türkiye’nin yürürlükte olan bir Gümrük Birliği Anlaşması ve 21 tane Serbest Ticaret Anlaşması (STA) bulunmaktadır. Bu çalışmanın amacı da Türkiye’nin STA’larını analiz etmektir. Çalışmada ulaşılan bulgulara göre Türkiye’nin STA kapsamındaki ticareti yeterli düzeyde değildir. Ayrıca Türkiye’nin imzaladığı STA’ların derinliği de oldukça düşüktür. Türkiye’nin ticaretini arttırmak ve daha fazla yatırım çekmek için derin ticaret anlaşmaları imzalaması gerekmektedir.

BONE CYLINDERS, DISCS AND TERMINALS-SCROLL HOLDERS FROM ROMAN FUNERARY DEPOSITS?
Authors: Greep Stephen , Rijkelijkhuizen Marloes
Published: February 2020

Complete and fragmentary elements of well made, composite, bone objects have been excavated in funerary contexts from the Roman period in North-western Europe; our work suggests that these forms belong primarily to the mid second and earlier third centuries. Researchers have described different possible functions of these objects, but to date none have been entirely satisfactory. The assemblage consists of several lathe-turned bone elements —two connected cylinders, and on both ends a disc and small knob or terminal. This paper considers the small number of complete assemblages recovered as secondary grave goods and uses this evidence to interpret a wider range of similar but incomplete finds, sometimes also placed in graves as secondary grave goods, but mainly recovered as primary, pyre debris. Previous interpretations of their use are rejected in favour of an identification as papyri scroll holders.
ARCHAEOLOGICAL AND ETHNOGRAPHIC INSIGHTS ON THE OCCURRENCE AND USE OF BONE ANVILS IN MALLORCA (BALEARIC ISLANDS, SPAIN)
Authors: Valenzuela Oliver Alejandro , Moreno-García Marta
Published: February 2020

After most researchers have agreed to interpret the bone anvils as artefacts used by blacksmiths to cut teeth on metal sickles, present lines of enquiry are focused on drawing the geographic and chronological scope of these tools. Following this path, this paper presents the results of archaeological and ethnographic surveys carried out in Mallorca (Balearic Islands, Spain). The new data recorded not only has enabled us to document the presence and temporal scope of the bone anvils on the island, but also, for the first time, the involvement of women in their use.
ANÁLISIS ESTADÍSTICO DE LAS DATACIONES RADIOCARBÓNICAS DE LA MOTILLA DEL AZUER (DAIMIEL, CIUDAD REAL)
Authors: Najera Trinidad , Molina Fernando , Cámara Juan Antonio , Afonso José A. , Spaneda Liliana
Published: February 2020

Las 70 dataciones radiocarbónicas, de las 80 realizadas en la Motilla del Azuer, incluidas en este trabajo proceden en su mayoría de muestras vegetales de vida corta y de restos humanos y faunísticos. Se pretende realizar diversos análisis estadísticos de las citadas dataciones como suma de probabilidades y análisis bayesianos (a partir de los programas Calib, BCal y OxCal), a fin de definir mejor la secuencia de ocupación del yacimiento y obtener un marco cronológico más detallado para situar en el tiempo los cambios ambientales y socioeconómicos que tuvieron lugar a lo largo de la ocu- pación del asentamiento. Los resultados muestran una primera ocupación calcolítica del yacimiento de escasa entidad separada de la fundación de la fortificación de la Edad del Bronce por un hiatus bien definido. La ocupación de la Motilla del Azuer desde el Bronce Antiguo hasta un momento avanzado del Bronce Tardío es continua y viene marcada por diversas fases de reconstrucción y ampliación de la fortificación que afectan también al pozo y a las estructuras hidráulicas situadas en el patio oriental del recinto fortificado. Del análisis de estos datos se desprende que la periodización publicada para la Motilla del Azuer es válida y muestra, en un marco de progresiva y fuerte jerarquización social, que la sucesión de diferentes episodios climáticos fue un factor crucial en el desarrollo de un sistema de asentamiento específico en La Mancha durante la Edad del Bronce.

Abstract: The purpose of this paper is to describe the development of 21st century skills in learning physics in high schools using creative problem solving models. This writing is motivated by the demands of the 21st century that education should be able to produce human resources capable of mastering 21st century skills including, critical thinking, communicative, creative and collaborative. The development of 21st century skills can be done by all disciplines, one of them is in learning physics. To develop 21st century skills in learning physics, educators can use creative problem solving models. The method used in this paper is to study literature by studying some literature to be analyzed and made conclusions. The results of this paper conclude that the creative problem solving learning model can be a solution in improving 21st century skills and motivating students to be more active and motivated in their learning success. The creative problem solving model is applied to students in high schools with several steps including clarifying the problem, expressing opinions, evaluating and selecting and implementing.
Transient analysis of a current driven full wave AC/DC converter for indirect characterisation of piezoelectric devices during energy harvesting
Authors: Bowen Chris
Published: February 2020

This paper provides a new approach to extract piezoelectric energy harvester properties, namely capacitance and current, from the increase of voltage with time on a storage capacitor after full wave rectification. The work provides a derivation of a more complete expression for the development of the output voltage with time, from which the equilibrium expression employed in earlier publications appears as a limiting case. This new formulation enables an accurate estimate of the sinusoidal driving current and the shunt capacitance to be made without recourse to direct measurement. Using the analysis with both simulated and experimental data, a four-step procedure is proposed that requires only the measurement of the initial slope of the voltage-time profile and the final settling value. This approach allows the much studied method of converting the piezoelectric output into charge stored on a capacitor to provide a unique indirect measurement method of the driving current and device capacitance under the conditions of frequency, temperature, stress and strain experienced by the piezoelectric energy harvester during operation.

IDEOLOGI BAHASA POLITIK SOEKARNO: SARANA KETAHANAN, KEAMANAN, DAN PERDAMAIAN INDONESIA
Authors: Latupeirissa David Samuel , Dami Zummy Anselmus
Published: February 2020

The current study aims at: (1) to explore the ideology conceived in Soekarno’s political language as one of the nation founding fathers and the proclaimer of Indonesia independence, (2) to explore the motivations behind the birth of ideology in the language, and (3) to see the socio-cultural changes as the result of Soekarno’s political ideology. To achieve the research objectives, researcher used Critical Discourse Analysis Theory (CDA) of Fairclough (1989, 1995, 2005, 2006) as the main theory, and the theory of Ideology as a supporting theory. The method applied in data collection was documentation method, while the method applied in data analysis was descriptive qualitative method that applied based on three analysis levels of Fairclough CDA theory. The results show that the ideology contained in Soekarno’s political language is the ideology of ‘unity as an important thing’, the ideology of ‘revolution as an integral part of the Indonesian nation soul’, and the ideology of ‘imperialism as the main enemy of the Indonesia’. The ideology needs to be lived for the sake of Indonesia’s endurance, security and peace. Furthermore, the ideology is based on a plural nation state and the realization that static nature is a barrier to the progress of a nation. The ideology contents have brought changes in the way of communication and the way of Indonesian nation life.
Bias in Bias Recognition: People View Others but not Themselves as Biased by Preexisting Beliefs and Social Stigmas
Authors: Wang Qi , Jeon Hee Jin
Published: February 2020

Biases perpetuate when people think that they are innocent whereas others are guilty of biases. We examined whether people would detect biased thinking and behavior in others but not themselves as influenced by preexisting beliefs (myside bias) and social stigmas (social biases). The results of three large studies showed that, across demographic groups, participants attributed more biases to others than to themselves and that this self-other asymmetry was particularly salient among those who hold strong beliefs about the existence of biases (Study 1 and Study 2). The self-other asymmetry in bias recognition dissipated when participants made simultaneous predictions about others’ and their own thoughts and behaviors (Study 3). People thus exhibit bias in bias recognition and this metacognitive bias may be remedied by highlighting to people that we are all susceptible to biasing influences.
