Information: - A newsletter is a regularly distributed publication that is generally about one main topic of interest to its subscribers. Newspapers and leaflets are types of newsletters. For example, newsletters are distributed at schools to inform parents about things that happen in that school. Newsletters are published by clubs, churches, societies, associations, and businessesespecially companiesto provide information of interest to members, customers, or employees. Google's definition of a newsletter is, "a bulletin issued periodically to the members of a society, business, or organization." A newsletter may be considered "grey literature". Newsletters delivered electronically via email (e-newsletters) have gained rapid acceptance for the same reasons email in general has gained popularity over printed correspondence. - SIGMOBILE is the Association for Computing Machinery's Special Interest Group on Mobility of Systems, Users, Data and Computing, which specializes in the field of mobile computing and wireless networks and wearable computing. - Mobile Computing and Communications Review ( MC2R ) is a peer - reviewed quarterly scientific journal and newsletter published by the ACM SIGMOBILE covering mobile computing and networking . The purpose of the journal is the rapid publication of completed or in - progress technical work , including articles dealing with both research and practice . The journal also covers the status of major international standards in the field , and news of conferences and other events . - Research comprises "creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories. A research project may also be an expansion on past work in the field. Research projects can be used to develop further knowledge on a topic, or in the example of a school research project, they can be used to further a student's research prowess to prepare them for future jobs or reports. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, or the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, social, business, marketing, practitioner research, life, technological,etc. - Humancomputer interaction (commonly referred to as HCI) researches the design and use of computer technology, focused on the interfaces between people (users) and computers. Researchers in the field of HCI both observe the ways in which humans interact with computers and design technologies that let humans interact with computers in novel ways. - A Special Interest Group (SIG) is a community within a larger organization with a shared interest in advancing a specific area of knowledge, learning or technology where members cooperate to affect or to produce solutions within their particular field, and may communicate, meet, and organize conferences. The term originated on CompuServe, an early online service provider, where SIGs were a section of the service devoted to particular interests. - In academic publishing, a scientific journal is a periodical publication intended to further the progress of science, usually by reporting new research. There are thousands of scientific journals in publication, and many more have been published at various points in the past (see list of scientific journals). Most journals are highly specialized, although some of the oldest journals such as "Nature" publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that have been peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. If the journal's editor considers the paper appropriate, at least two researchers preferably from the same field check the paper for soundness of its scientific argument, and must agree to publish it. Although scientific journals are superficially similar to professional magazines, they are actually quite different. Issues of a scientific journal are rarely read casually, as one would read a magazine. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record. - The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to specific principles of reasoning. The Oxford Dictionaries Online define the scientific method as "a method or procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses". Experiments need to be designed to test hypotheses. The most important part of the scientific method is the experiment. - The Association for Computing Machinery (ACM) is an international learned society for computing. It was founded in 1947 and is the world's largest scientific and educational computing society. It is a not-for-profit professional membership group. Its membership is more than 100,000 as of 2011. Its headquarters are in New York City. - Mobile computing is humancomputer interaction by which a computer is expected to be transported during normal usage, which allows for transmission of data, voice and video. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications.
