Problem: Given the question: Information:  - Public health refers to "the science and art of preventing disease, prolonging life and promoting human health through organized efforts and informed choices of society, organizations, public and private, communities and individuals." It is concerned with threats to health based on population health analysis. The population in question can be as small as a handful of people, or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). The dimensions of health can encompass "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity," as defined by the United Nations' World Health Organization. Public health incorporates the interdisciplinary approaches of epidemiology, biostatistics and health services. Environmental health, community health, behavioral health, health economics, public policy, insurance medicine, mental health and occupational safety and health are other important subfields.  - Social science is a major category of academic disciplines, concerned with society and the relationships among individuals within a society. It in turn has many branches, each of which is considered a "social science". The main social sciences include economics, political science, human geography, demography, and sociology. In a wider sense, social science also includes some fields in the humanities such as anthropology, archaeology, jurisprudence, history, and linguistics. The term is also sometimes used to refer specifically to the field of sociology, the original 'science of society', established in the 19th century. A more detailed list of sub-disciplines within the social sciences can be found at Outline of social science.  - Walkability is a measure of how friendly an area is to walking. Walkability has health, environmental, and economic benefits. Factors influencing walkability include the presence or absence and quality of footpaths, sidewalks or other pedestrian rights-of-way, traffic and road conditions, land use patterns, building accessibility, and safety, among others. Walkability is an important concept in sustainable urban design.  - Environmental social science is the broad, transdisciplinary study of interrelations between humans and the natural environment. Environmental social scientists work within and between the fields of anthropology, communication studies, economics, geography, history, political science, psychology, and sociology; and also in the interdisciplinary fields of environmental studies, human ecology and political ecology, among others.  - Bikeability is the national programme for cycle training in England, Wales, and Scotland. The programme is purely voluntary - schools may sign up to host classes for children. Adults may also join classes. In England and Wales, the programme is based on the National Standard for Cycle Training, a UK Government standard run by the Department for Transport and approved by RoSPA, Road Safety GB, British Cycling, CTC, Sustrans and Cycling England.  - This is a list of scholarly , peer - reviewed academic journals focused on the biophysical environment and / or humans ' relations with it . Inclusion of journals focused on the built environment also is appropriate . Included in this list are journals from a wide variety of interdisciplinary fields including from the environmental sciences , environmental social sciences , environmental humanities , etc.  - In social science, the term built environment refers to the man-made surroundings that provide the setting for human activity, ranging in scale from buildings and parks. It has been defined as "the humanitarian-made space in which people live, work, and recreate on a day-to-day basis." The "built environment encompasses places and spaces created or modified by people including buildings, parks, and transportation systems." In recent years, public health research has expanded the definition of "built environment" to include healthy food access, community gardens,mental health, "walkability" and "bikeability."    What is the relationship between 'list of environmental journals' and 'environmental studies'?

Problem: Given the question: Information:  - Guitar Hero Encore : Rocks the 80s ( titled Guitar Hero : Rocks the 80s in Europe ) is a music rhythm game and the third installment in the popular Guitar Hero series . It was released in July 2007 in North America and Europe , and in August 2007 in Australia . Players use a guitar - shaped controller ( purchased separately ) to simulate playing rock music by hitting notes as they scroll towards the player . Rocks the 80s is an incremental title in the Guitar Hero series , rather than a full sequel . No changes in gameplay from Guitar Hero II have been introduced to this game . As implied by the game 's title , the game features a 1980s theme , consisting of songs from the decade and playable characters , fashions , and artwork that reflect the time period . The game was not as well - received as the prior two Guitar Hero games , due to the lack of new gameplay features and reduced soundtrack . Rocks the 80s is the third and final title in the Guitar Hero series to be developed by Harmonix before they moved on to create Rock Band . The next major installment of the series , Guitar Hero III : Legends of Rock , was developed by Activision 's Neversoft division .  - A game controller is a device used with games or entertainment systems to provide input to a video game, typically to control an object or character in the game. A controller is usually connected to a game console or computer by means of a wire or cord, although, since the mid-2000s, wireless controllers have become widespread. Input devices that have been classified as game controllers include keyboards, mouses, gamepads, joysticks, etc. Special purpose devices, such as steering wheels for driving games and light guns for shooting games, are also game controllers.  - A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental and/or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers. In classical music, trios or quartets either blend the sounds of musical instrument families (such as piano, strings, and wind instruments) or group together instruments from the same instrument family, such as string ensembles (e.g., string quartet) or wind ensembles (e.g., wind quintet). Some ensembles blend the sounds of a variety of instrument families, such as the orchestra, which uses a string section, brass instruments, woodwinds and percussion instruments, or the concert band, which uses brass, woodwinds and percussion.   - Rhythm game or rhythm action is a genre of music-themed action video game that challenges a player's sense of rhythm. Games in the genre typically focus on dance or the simulated performance of musical instruments, and require players to press buttons in a sequence dictated on the screen. Doing so causes the game's protagonist or avatar to dance or to play their instrument correctly, which increases the player's score. Many rhythm games include multiplayer modes in which players compete for the highest score or cooperate as a simulated musical ensemble. While conventional control pads may be used as input devices, rhythm games often feature novel game controllers that emulate musical instruments. Certain dance-based games require the player to physically dance on a mat, with pressure-sensitive pads acting as the input device.
