Implant-supported restorations can be secured to implants with screws (screw-retained), or they can be cemented to abutments which are attached to implants with screws (cement-retained). This literature review discusses the advantages and disadvantages of each method of retention from different aspects. These aspects include: ease of fabrication and cost, esthetics, access, occlusion, retention, incidence of loss of retention, retrievability, clinical prosthesis fit, restriction of implant position, effect on peri-implant tissue health, provisionalization, immediate loading, impression procedures, porcelain fracture, and clinical performance. Peer-reviewed literature published in the English language between 1955 and 2010 was reviewed using PubMed and hand searches. Since the choice of using either method of retention is still controversial, this review article offers some clinical situations that prefer one method of retention over the other. The review demonstrated that each method of retention has certain advantages and disadvantages; however, there are some clinical situations in which it is better to select one method of retention rather than the other.

This Preface contains six sections. The author analyses the works of the most distinguished thinkers of Islam and human rights: Mahmoud Mohamed Taha, Abdullahi Ahmed An-Na‘im, Ann Elizabeth Mayer, Mohammad Mojtahed Shabestari and Abdulaziz Sachedina respectively in the first five sections. Each section has two parts: the first is a brief description of the thinker’s opinion on human rights, and the second is a brief critical analysis, reviewing the advantages and disadvantages of that opinion. Taha represents the Arabic literature on Islam and human rights in this review, Shabestari the Persian, and the other three the English-language literature. Mayer is the author of the most popular book on Islam and human rights from a non-Muslim and Western perspective. The other four could be considered to be the most outstanding Muslim reformist thinkers regarding Islam and human rights. The last section is the longest and contains four parts. The first outlines the author’s opinion on Islam and human rights, and the second compares his approach to the other five approaches.

Abstract The number of marketing communications tools and channels is steadily increasing – in addition, this growth has been accelerated since the emergence of the Internet and social media. On the one hand, there is an increasing dilemma of which tools one should choose from the plentiful options, and, on the other hand, the (material, human, and time) resources devoted to this are limited. This is valid for the marketing communications of “classic” products, services, and countries. This review article attempts to present the variety of available options with the help of the POE (paid, owned, earned) model and describe their advantages and disadvantages. The novelty of the study is that it focuses on a review of country communication campaigns and initiatives. It offers various visual examples for the different components of the POE model, clarifying the paid media, owned media, and earned media options for country brand communication. It mostly uses examples from Hungary, but other countries’ good practices are also included. Finally, as a result of the analysis, the article summarizes the possible ways of country brand communication according to the POE model in a summary table, which may also contribute to the work of academics and practitioners in the field.

This research articulates problems and strategies in translating text from English as the source text to Indonesia language as the target text. By reviewing and analysing critically mélange of concepts, examples and findings explained in some collected references, it is known that problems in translation mostly are around lexical, grammatical and semantic elements. In the other hand, the strategies used to produce acceptable translation result regarding to the readers’ of target text understanding have to consider aspects such as cultural content, the availability of equivalencies, and the ability to use the monolingual dictionary. This research also try to emphasize and to convince why finding problems and strategies of EFL student teachers in translating text is very prominent to help the mapping of which elements in English language that are still hard to be transmitted back to Indonesia language and how to overcome that problems.

This paper discusses the sense of Accent. This article offers a summary of the various recognizable shifts in the pronunciation of local dialects and the general variations in the standard English of different primary speaking populations. Accent is the component of the local pronunciation dialect. Grammar and vocabulary are otherwise mentioned. Secondary speakers of English prefer to use their mother tongue's intonation and phonetics in English speaking. The English primary speakers exhibit great regional diversity. Some of them are easily recognized by key features, such as Pennsylvania Dutch English; others are darker or more ambiguous. Broad regions may have sub-forms, as shown below. For example, cities less than 10 miles (16 km) away from Manchester city, such as Bolton, Rochedale, Oldham, and Salford have distinct accents that all together form part of the larger accents of the province of Lancashire. Australia has a "General accent" emphasis on the other side of the continuum, which is basically consistent in tens of miles. The accents of English can differ enough to give room for misunderstanding. In certain varieties of Scottish English, for example, the pronunciation of pearl can sound like petal to an American ear.

Drawing on research about young children’s literacy development, this review article discusses a recent paradigmatic turn for understanding the child and childhood from human-centerism to posthumanism. Building on the new materialist tradition (e.g., Barad, 2007) and the assemblage theory of Deleuze and Guattari (1987, 1997), the posthuman lens enables researchers and educators to see children as parts of entangled networks of relationships who continuously intra-act with their peers, teachers, materials, and the other nonhuman entities and activities produced constantly by the child-material entanglements. As such, the posthumanist perspective expands the current research on early literacy by offering new possibilities for re-conceptualizing the child, the materials or resources for early literacy, and the meaning of childhood and children’s play. These new ways of seeing the child, the materials, and childhood have also generated new pedagogical practices that are material-oriented, intra-active, and flexible. The review concludes by providing directions for conducting research from a posthuman perspective in the field of early literacy education.

The number of English Language Learners (ELL) is increasing in all regions of the United States. Although the majority (71%) speak Spanish as their first language, the other 29% may speak one of as many as 100 or more different languages. In spite of an increasing number of speech-language pathologists (SLPs) who can provide bilingual services, the likelihood of a match between a given student's primary language and an SLP's is rather minimal. The second best option is to work with a trained language interpreter in the student's language. However, very frequently, this interpreter may be bilingual but not trained to do the job.

Zakat is one of principal worship requiring every individual (<em>mukallaf</em>) with considerable property to spend some of the wealth for zakat under several conditions applied within. On the other hand, tax is an obligation assigned to taxpayers and should be deposited into the state based on policies applied, with no direct return as reward, for financing the national general expense. In their development, both zakat and tax had quite attention from Islamic economic thought. Nevertheless, we, at first, wanted to identify the principles of zakat and tax at the time of Rasulullah SAW. Therefore, this study referred to normative research. The primary data was collected through library/document research and the secondary one was collected through literature review by inventorying and collecting textbooks and other documents related to the studied issue.


The main methods (pressing and winding) of the processing of hybrid polymer composites to obtain items were examined. Advantages and disadvantages of the methods were noted. Good combinations of different-module fibers (carbon, glass, boron, organic) in hybrid polymer materials are described, which allow one to prepare materials with high compression strength on the one hand, and to increase fracture energy of samples and impact toughness on the other hand.
