International products and purchase intention in Jordan among consumer ethnocentrism

This study attempts to validate the Antecedents of Consumer Ethnocentrism and determine causal relationships between the specified antecedents and customer ethnocentrism in light of customer behavior in a less developed country Jordan. Seven antecedents were identified: culture openness, conservatism, collectivism, patriotism, control belief, interest in foreign travel and attitude toward foreign product. Each variable is measured by a 7-point Likert-scale of various developed past scales. Consumer ethnocentrism was measured using the CETSCALE 17 items. An 84 percent response rate was collected from 120 questionnaires distributed. Confirmatory factor analysis performed on the data reveals that the measurement model and structural model are statistically fit. Structural equation modeling (SEM) analysis establishes causal relationships between cultural openness, control belief, foreign travel, attitude and ethnocentrism

Evaluation of PPG Biometrics for Authentication in different states

Amongst all medical biometric traits, Photoplethysmograph (PPG) is the easiest to acquire. PPG records the blood volume change with just combination of Light Emitting Diode and Photodiode from any part of the body. With IoT and smart homes' penetration, PPG recording can easily be integrated with other vital wearable devices. PPG represents peculiarity of hemodynamics and cardiovascular system for each individual. This paper presents non-fiducial method for PPG based biometric authentication. Being a physiological signal, PPG signal alters with physical/mental stress and time. For robustness, these variations cannot be ignored. While, most of the previous works focused only on single session, this paper demonstrates extensive performance evaluation of PPG biometrics against single session data, different emotions, physical exercise and time-lapse using Continuous Wavelet Transform (CWT) and Direct Linear Discriminant Analysis (DLDA). When evaluated on different states and datasets, equal error rate (EER) of $0.5\%$-$6\%$ was achieved for $45$-$60$s average training time. Our CWT/DLDA based technique outperformed all other dimensionality reduction techniques and previous work.Comment: Accepted at 11th IAPR/IEEE International Conference on Biometrics, 2018. 6 pages, 6 figure

Competing Universalities in Kardar-Parisi-Zhang (KPZ) Growth Models

We report on the universality of height fluctuations at the crossing point of two interacting (1+1)-dimensional Kardar-Parisi-Zhang (KPZ) interfaces with curved and flat initial conditions. We introduce a control parameter p as the probability for the initially flat geometry to be chosen and compute the phase diagram as a function of p. We find that the distribution of the fluctuations converges to the Gaussian orthogonal ensemble Tracy-Widom (TW) distribution for p0.5. For p=0.5 where the two geometries are equally weighted, the behavior is governed by an emergent Gaussian statistics in the universality class of Brownian motion. We propose a phenomenological theory to explain our findings and discuss possible applications in nonequilibrium transport and traffic flow.Comment: 5 pages, 6 figures, Phys. Rev. Lett.

M-ATTEMPT: A New Energy-Efficient Routing Protocol for Wireless Body Area Sensor Networks

In this paper, we propose a new routing protocol for heterogeneous Wireless Body Area Sensor Networks (WBASNs); Mobility-supporting Adaptive Threshold-based Thermal-aware Energy-efficientMulti-hop ProTocol (M-ATTEMPT). A prototype is defined for employing heterogeneous sensors on human body. Direct communication is used for real-time traffic (critical data) or on-demand data while Multi-hop communication is used for normal data delivery. One of the prime challenges in WBASNs is sensing of the heat generated by the implanted sensor nodes. The proposed routing algorithm is thermal-aware which senses the link Hot-spot and routes the data away from these links. Continuous mobility of human body causes disconnection between previous established links. So, mobility support and energy-management is introduced to overcome the problem. Linear Programming (LP) model for maximum information extraction and minimum energy consumption is presented in this study. MATLAB simulations of proposed routing algorithm are performed for lifetime and successful packet delivery in comparison with Multi-hop communication. The results show that the proposed routing algorithm has less energy consumption and more reliable as compared to Multi-hop communication.Comment: arXiv admin note: substantial text overlap with arXiv:1208.609

Working memory learning method and astrocytes number in different subfields of rat's Hippocampus

The aim of this study was evaluation of the astrocytes number in different subfields of rat's Hippocampus after spatial learning with usage of Morris Water Maze technique and working memory method. In this study, between 2005-2006 years in Pasteur institute of Iran-Tehran and histological department of Gorgan University with usage of Morris Water Maze and working memory technique, we used 14 male albino wistar rats. Seventh rats were in control group and 7 rats in working memory group. After histological preparation, the slides were stained with PTAH staining for showing the Astrocytes. Present results showed significant difference in astrocytes number in CA1, CA2 and CA3 areas of hippocampus between control and reference memory group. The number of astrocytes is increased in working memory group. Then we divided the hippocampus to three parts: Anterior, middle and posterior and with compare of different area (CA1, CA2 and CA3) of hippocampus, we found that the differences between Anterior-middle and Middle-Posterior of CA1 and CA2 area of hippocampus were significant, whereas the difference between Anterior-Posterior parts was not significant in CA1 and CA2 areas. In CA3 area, the difference between Anterior-Middle and Anterior-Posterior parts was significant, whereas the difference between middle and posterior parts was not significant. We concluded that the number of astrocytes increased due to spatial learning and working memory technique. © 2008 Science Publications

Perkembangan Teknologi Di Bidang Produksi Pangan Dan Obat-obatan Serta Hak-hak Konsumen

Nowadays, the regulation on food and drugs is considered to be clear and sufficient. However, the duty to examine, supervise and to avoid the dangers which are possible to happen, is not yet been undertaken. In addition to this, thre is no relevant body establisehed for such puposes. Therefore, the wise step to avoid any negative impacts of food and drugs is by incepting a regulation to supervise importing, consuming and the sirculation of such products

Muhammad Abduh : Konsep Rasionalisme Dalam Islam

; Muhammad Abduh seorang Pemikir Pembaru Islam yang sangat berpengaruh di dalam sejarah pemikiran Islam. Pemikirannya membawa dampak yang signifikan dalam berbagai tatanan kehidupan pemikiran masyarakat meliputi aspek penafsiran Al-Qur\u27an, pendidikan, social masyarakat, politik, peradaban dan sebagainya. Islam adalah agama yang terdiri dari beberapa aspek yang saling berhubungan, satu dengan yang lainnya. Yaitu Aqidah (Teologi), Syariah (Hukum Islam), dan Akhlak (tasawuf). Namun dalam hal ini, penulis memilih fokus pembahasan pada pemikiran dalam bidang akidah (teologi) dan hukum karena kedua ini sangat menentukan kehidupan seseorang dalam bertindak. Kepercayaan pada kekuatan akal, membawa Muhammad Abduh selanjutnya kepada faham yang mengatakan bahwa manusia mempunyai kebebasan dalam kemauan dan perbuatan. Dalam teologi dan falsafah terdapat dua konsep mengenai hal tersebut. Pertama, pendapat mengatakan bahwa semua perbuatan manusia telah ditentukan semenjak aza, sebelum ia lahir, dan faham ini dalam teologi Islam disebut jabariah. Dalam teologi Barat pendapat ini disebut fatalisme atau predestination. Kedua, bahwa manusia mempunyai kebebasan sungguh pun terbatas sesuai dengan keterbatasan manusia dalam kemauan dan perbuatan. Faham ini dalam Islam disebut qadariyah, dan dalam teologi Barat disebut free will and free act. Pemikiran Muhammad Abduh sangat berpengaruh dalam dunia Islam baik di Mesir maupun negara-negara Arab lainnya, sehingga muncul ulama-ulama modern seperti Mustafa al-Maraghi, Mustafah Abd Raziq, Tantawi Jauhari, Ali Abd al-Raziq dan Rasyid Ridha, pengarang-pengarang dalam bidang agama seperti Farid Wajdi, Ahmad Amin, Qasim Amin juga di Indonesia tidak sedikit gerakan pembaruan yang dicetuskan sepert Ahmad Surkati dan gerakan al-Irsyad, Ahmad Dahlan dan gerakan Muhammadiyah dll. Kata Kunci: Konsep, Rationalisme Muhammad Abduh an Islamic reformer thinker who is very influential in the history of Islamic thought. Their thinking is a significant impact on the livelihood of various aspects of people\u27s minds include interpretation of the Qur\u27an, educational, social, society, politics, civilization and so on. Islam is a religion which consists of several interrelated aspects, one with the other. That Aqeedah (theology), Sharia (Islamic law), and Morals (Sufism). But in this case, the authors chose to focus the discussion on the thinking in the field of Aqeedah (theology) and the second law because it largely determines the life of someone in the act. The belief in the power of reason, bringing Muhammad Abduh next to the ideology that says that man has the freedom to will and deed. In theology and philosophy, there are two concepts about it. First, it argued that all human actions have been determined since aza, before he was born, and this ideology in Islamic theology called jabariah. In the opinion of Western theology is called fatalism or Predestination. Secondly, that man has the freedom really is limited in accordance with the limitations of the human will and deed. This ideology in Islam called Qadariyah, and in Western theology is called free will and free act. Thought Muhammad Abduh very influential in the Islamic world both in Egypt and other Arab countries, making it appear modern scholars such as Mustafa al-Maraghi, Abd Mustafah Raziq, Tantawi Jauhari, Ali Abd al-Raziq and Rashid Rida, authors in field of religion as Farid Wajdi, Ahmad Amin, Amin Qasim also in Indonesia is not the slightest movement triggered updates sepert Ahmad Surkati and movement al-Irshad Ahmad Dahlan and Muhammadiyah movement etc. Keywords: Concept, Rationalis

A Mechanism for Securing IoT-enabled Applications at the Fog Layer

The Internet of Things (IoT) is an emerging paradigm branded by heterogeneous technologies composed of smart ubiquitous objects that are seamlessly connected to the Internet. These objects are deployed as Low power and Lossy Networks (LLN) to provide innovative services in various application domains, such as smart cities, smart health, smart communities. The LLN is a form of a network where the interconnected devices are highly resource-constrained (i.e., power, memory, and processing) and characterized by high loss rates, low data rates and instability in the communication links. Additionally, IoT devices produce a massive amount of confidential and security-sensitive data. Various cryptographic-based techniques exist that can effectively cope with security attacks, but are not suitable for IoT as they incur high consumption of resources (i.e., memory, storage and processing). One way to address this problem is by offloading the additional security-related operations to a more resourceful entity such as a fog-based node. Generally, fog computing enables security and analysis of latency-sensitive data directly at the network’s edge. This paper proposes a novel Fog Security Service (FSS) to provide end-to-end security at fog layer for IoT devices, using two well-established cryptographic schemes, identity-based encryption and identity-based signature. The FSS provides security services, such as authentication, confidentiality, and non-repudiation. The proposed architecture is implemented and evaluated in OPNET simulator using a single network topology with different traffic loads. The FSS performed better when compared with the APaaS and the legacy method
