Abstract:
This article investigates the role that community media play in the translocal negotiation of local culture in Latin America. Translocal is a concept that captures the way that local cultural producers engage with national and transnational forces in shaping everyday cultural practices. This study focuses on community radio station Ecos de Manantlán in Zapotitlán de Vadillo, Mexico (Radio Zapotitlán), during the years 2006–2012. Radio Zapotitlán is officially categorized as a campesino or agricultural laborer/peasant station and presents its campesino identity through radio and Internet content. Analyses of that content, along with interviews with station associates and listeners, reveal the complex cultural mediations between local media producers, national regulators, and transnational donors. This study investigates the local production of a transnationally funded radionovela, or radio soap opera, as a window onto the station’s role as a cultural mediator. This article argues that station participants used the radionovela to express local values and meanings and to marginalize the educational goals of the transnational agency funding the project. Radio Zapotitlán offers a concrete case of cultural negotiation in which local interests engage with – and transform – donor-funded content aimed at the local community.

Abstract:
Community radio has been defined by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as promoting non-profit ownership of stations and volunteer participation. The increasing commercialisation of community radio in Canada, evident in changing station practices and regulatory policies, has resulted in the erosion of volunteer run governance and programming. This article draws on community media, anti-oppression, and third-sector studies literature to investigate the experiences of volunteers from two stations, CHRY in Toronto and Radio Centre-Ville in Montral. Current Canadian Radio-television and Telecommunications Commission (CRTC) regulations define community radio by virtue of its place in the communities served. This article concludes that reducing the engagement and empowerment of volunteers in community radio programming and governance limits the place of community radio in the community. The authors will also identify best practices that are needed to re-centre community radio within the community while ensuring a sustainable non-profit community broadcasting sector.

Abstract:
This article is aimed at evaluating the contributions of community radios to the development of regions. Qualitative and quantitative research designs were adopted added to secondary data (published, unpublished sources and the internet). The data derived was coded and analysed to come out with the following findings that Donga-Mantung community radio has significantly contributed to the local development of the division in the following ways. First, the community radio contributes to improvement in the agricultural activities of the local population. Second, the Donga Mantung community radio helps in promoting the culture of the people as well as the general sensitisation of the people. Third, the station has provided a forum for Small and Medium Size Enterprises (SMEs) to reach out to the larger population by undertaking advertisements at very affordable fees. Fourth, the station contributes in sensitising the public on health issues focusing on AIDS prevention, vaccination and family planning.

Abstract:
This article examines the connections between prisoners' radio and community, drawing on a case study of an annual Indigenous prisoners' radio project from Melbourne, Australia called Beyond the Bars, coordinated by community radio station 3CR. It demonstrates that an important aspect of prisoners' radio is its ability, as a media form, to sustain relationships between those inside and outside of incarceration, and as a result maintain community connections. The success of Beyond the Bars as a whole can be attributed in part to the special relationship forged between the local Indigenous community and the radio station itself, which has featured over 30 years of Indigenous broadcasting.

Abstract:
Decree No. 38 of 1992 enacted under the administration of General Ibrahim B. Babangida put a stop to fifty seven years of government’s exclusive ownership and operation of broadcasting in Nigeria. However, with the cost of setting-up, management and obtaining license for media station being prohibitively expensive, the system can only be accessed by the rich and powerful in the society, thereby depriving rural communities’ involvement in the development of the country. As part of the panoply of strategies to ensure rural communities’ participation in democratic governance, there is need for the establishment of rural community radio stations, which is very much different from educational institutions’ type currently being paraded as community radios but rather a training room for communication and theatre arts students. Using historical-analytic method, this article looks at the role community radio could play in making good governance in Nigeria accessible to every segment of society, especially the rural populace. Therefore, it is recommended that Nigerian Broadcasting Commission (NBC) policy should consider the inclusion of community radio as the third in the sector of radio broadcasting in Nigeria after public and commercial ownership. Furthermore, since community radio is essentially non-for-profit, government should make the operation licence free or at a minimal cost to the host community.

Abstract:
The Australian community radio sector is a rich source of information for researchers, activists and practitioners working to support and develop community broadcasting worldwide. With a 46-year history, it represents an established and enduring third tier of independent local broadcasting with over 450 non-profit radio services legislated to provide opportunities for community engagement and participation. This article focuses on the political, economic and institutional factors involved in a change of ownership and management of Radio Adelaide, the countrys longest running community radio station. The process illustrates the impact and effects of the non-profit industrial complex as stations struggle for financial survival and independence in an increasingly competitive, corporatized environment. It is a case study which questions the contemporary understanding of a strong and resilient sector, highlighting themes to inform community media research and practice internationally.

Abstract:
In the Declaration of the Committee of Ministers on the role of community media in promoting social cohesion and intercultural dialogue passed on 11 February 2009 by the Council of Europe, stations run by religious institutions were explicitly excluded from the community media definition, as being too dependent on the Church. But the reality seems to be far from this definition. In practice, in many countries the religious radio stations officially belong to—or even dominate—this sector. In 2011 a new period began for community broadcasting in Hungary. While most of the former community media broadcasters could not find resources with which to operate, the community media landscape was dramatically overwhelmed by religious broadcasters both on regional and local levels. The legally-recognised third tier of broadcasting in Poland called ‘social broadcasting’ is actively and exclusively used by religious radio—seven stations broadcast locally and one is a powerful nationwide radio station called Radio Maryja. The authors gathered information and points of views from radio experts, organizations and activists living and working in different EU and non-EU states about the place of religious broadcasting in the community media sector. Two case-studies (Hungary and Poland) may be of interest for countries considering the introduction or reorganisation of regulations regarding community broadcasting.

Abstract:
It's no secret that the representation of migrant groups in the media has been particularly problematic, as has been their access to mainstream media, and both issues have attracted a great deal of research. Far less attention has been paid by researchers to how these groups respond when they experience such difficulties, and the various forms of media they use to engage with a variety of issues pertinent to them and their settlement experiences. This article uses data from two projects: Australia's first, and to date only, national study of community radio audiences; and a more recent case study of a community radio station undertaken in the course of research into talkback radio audiences. It reveals that community radio stations and programs provide migrant communities with a space in which they can discuss and negotiate their civic and social rights and responsibilities. Drawing on the reflections of audience members who listen to and call specific radio programs, this article explores the under-examined but vital role performed by these stations and programs in the social and civic lives of immigrants. It reveals that ethnic community radio programs are helping some audience members to formulate notions of good citizenship, and thus engage with democratic processes, which is vital to feeling socially included. The research reveals immigrants are using community radio proactively to reach out to and connect with the broader Australian community, while also reminding themselves of their homeland, culture and language. However, this article warns that researchers have largely focused on the ‘good news story’ of community broadcasting and suggests that a more critical approach to future research is warranted.

Abstract:
The purpose of this treatise is a development of a suitable model for a community radio station which would lead to operational effectiveness and ensure sustainability. The treatise has three phases namely a theoretical phase, a narration phase and an integration phase. Firstly, in the theoretical phase the research study investigates what the literature review reveals about community radio stations and business models. This treatise argues that a total dependency of community radio stations on donor funding leads to operational ineffectiveness which threatens their sustainability. The treatise also argues that a business model could be adapted for a community radio station by identifying the business issues which the literature review revealed, and use these to deconstruct a theoretical business model. Secondly, in the narrative phase the research study investigates the important business issues for a selected community radio station. The treatise argues the board and management of this selected community radio station revealed additional business issues of operations and gave different ratings to business issues which are important in their operations. Thirdly, in the integration phase, the theoretical model deconstructed in the theoretical phase, was revised by including additional business issues of operations revealed in the narrative phase. The research study concludes that this revised model is a suitable business model for a community radio station and can lead to operational effectiveness and ensure sustainability.

Abstract:
This research set out to investigate the role that community radio can potentially play as a space in which young people engage with their own role as citizens and, in so doing, participate in discussions that seek to address social problems in a community divided by class, income, gender and race. The study examines how a local community radio station - Radio Grahamstown - developed a youth programme Y4Yin which the producers of the show and its audience came together to negotiate the meaning of citizenship. The study examines whether this interactive programme was able to function as something like a public sphere where in young people were able to develop a greater sense of agency, at least in the realm of citizenship. Using evidence gathered through focus group discussions with a group of young school-going leamers, interviews conducted with the producers of the show Y4Y, and drawing on Dahlgren's elaboration of a functional public sphere, the research concludes that the show provided a useful platform for Grahamstown high school students to develop their own notions of citizenship and to, at least partially and tentatively, build some 'bridges' across the vectors of socio-economic division in the town. However, the research also concludes that the Y4Y producers often failed to use a mode of address contemporary to the youth and often did not use production techniques congruent with young people's cultural tastes. This limited the programme's appeal and its potential as an enabler of discussion about notions of citizenship and as a platform for social bridging. In addition, because of the producers' control over the choice of topics put up for discussion, open interaction was more limited than could have been expected. In addition, the study also concludes that various limitations to the leamers' freedom of expression (including their fear that teachers might be listening in to the shows) inhibited the programme's role as a deliberative public sphere where issues could be aired, common ground found, and solutions discussed.

Abstract:
As Rádios Comunitárias exercem um papel importante nas comunidades em que estão inseridas. Além de ser um canal de expressão aberto à população local, permitem ao cidadão e à cidadã da periferia, excluídos digitalmente, culturalmente e socialmente utilizar as ondas hertzianas para se expressarem. O surgimento de milhares de rádios comunitárias em todo o país proporciona o início de um processo histórico de ruptura do monopólio dos meios de comunicação de massa. No âmbito da educação informal, as rádios comunitárias contribuem no processo da conquista da cidadania a partir da reflexão e da conscientização dos problemas e dos interesses coletivos.
Community radio stations have an important role in the communities in which they belong to. And aside from being an open channel expression for the local population, community radio stations allow periphery citizens, which are technological, cultural and socially excluded, to make use of Hertz vibration to express themselves. The thousands of community radio stations uprising all over the country provides the beginning of a historical process of breaking the media monopoly. In relation to informal education, community radio stations help in the process of citizenship conquest through reflection and the awareness of the problems and of the public concern.

Abstract:
Black voices on radio provided community building opportunities for African Americans. As such, blacks created an alternative public sphere which allowed them to engage in discourse that unifies people into a collective. The Urban League on the national and local levels aided community building by organizing its members to approach radio station managers beginning in 1941. The organization's directives led to the establishment of the “Negro Forum,” an Afrocentric talk show that integrated the airways in New Orleans in 1946. WNOE station owner James Noe provided O. C. W. Taylor 15 minutes of free airtime on Sundays from 10 a.m. to 10:15 a.m. Noe's decision to accept the “Religious Forum” was also influenced by his interest in gaining Federal Communications Commission approval to change his position on the dial and increase the station's broadcast power from 250 watts to 50,000 watts.

This chapter discusses the nature of participatory research by giving a case study of KCC Live, a volunteer youth-led community radio station in Knowsley, UK. It talks about the co-production of audio artefacts and illustrates how the young participants change the way scholars approached the term ‘participatory’. In addition, the chapter details how the methods evolved within the field, owing to the participatory design of the project. It problematises the alleged emancipatory potential of participatory research and, in detailing the co-production of audio artefacts in this project, argues that the meaning of ‘participatory’ in participatory research should be determined in communication with study participants. Only then can research be considered truly participatory.

This essay focuses on Latina/o claims to belonging in the community and the nation while working and living in Perry, Iowa. Attracted to jobs in the meatpacking industry, Latinas/os made connections to Perry and developed a sense of belonging despite feeling initially unwelcomed by the town’s residents. Among the challenges confronted by Latina/o residents were the policing of their use of Spanish, negative perceptions of a local Spanish-language radio station, and the racialization of Latinas/os as criminals and foreigners. By confronting these challenges and claiming a place in the community, Latinas/os demonstrated the changing nature of the rural heartland. The town’s Latinas/os characterized themselves as integral to the social, economic, and political fabric of their community and the nation.

Abstract:
During the period covered at the beginning of this chapter (the early 1990s), WAMU-FM and the Birchmere both still featured bluegrass; by the chapter’s close, in the contemporary period, this powerful radio station had completely transitioned to a news and talk format and the Birchmere only occasionally booked this genre. The sheer number of bands and venues diminished noticeably as did the general interest in bluegrass. The shrinkage of bluegrass programming on WAMU-FM was gradual and deliberate, occurring over some dozen years. The local bluegrass community vehemently protest, but to no avail. However, the existence of the WAMU-FM spin-off bluegrasscountry.org and the formation of DC Bluegrass Union reflect the existence of the ongoing, though diminished, local bluegrass community.

Full text
Abstract:
Werner Sander’s establishment of the Leipziger Synagogalchor as a concert choir with Jewish repertoire was relatively independent from any institutions. From his founding of the choir in 1962 to his death in 1972, Sander developed with the choir a repertoire of nearly eighty works of synagogue music and forty titles of Yiddish and Hasidic music, as well as Hebrew folklore. Under his baton, the choir performed three to four times a year, and from 1968 on assumed a steady role in the musical life of the GDR, both inside and outside the Jewish community. In spite of pressure, Sander preserved the secularity and independence of the ensemble by never overtly defining it or creating specific or lasting alliances, in a spatial mobility that navigated between different venues—synagogue, church, concert hall, and radio station. In this way, he ensured Jewish music’s cultural survival under unique and changing conditions, preserving this musical heritage for the Jewish community and transmitting it to the wider public.

Abstract:
Abstract The levels of pollution present in the air have been dramatically increasing over the years due to the continuous emission of greenhouse gases such as CO2, CO, NOx and H2S, among others. The main source of these emissions is from burning fossil fuels for electricity, heat, and transportation. This represents a tremendous risk to the populations located near the emission sources where people get exposed to dangerous concentrations of such gases on a daily basis. The lack of open real-time monitoring tools makes people unaware of the damage these pollutants cause to their health. This research proposes the development and implementation of a low-cost independent solution to keep the members of a community informed about concentration levels of air pollution due to local emissions. This tool must be easily accessible to the users so that the data about the number of particulates per million of a specific gas within a zone of interest can be viewed at any time. The proposed solution consists of a sensor network, covering the widest possible area, with respect to the point of interest. The collected data is sent to a cloud server, which operates as storage center and in which the data can be latter accessed for subsequent analysis. The measurements are sent to the server by means of a wireless communication protocol, carried out by a General Packet Radio Service, GPRS, communication module connected to each station. In this way, the coverage of the network is not limited by issues such as the use of local area networks which at the same time facilitates the transportation and installation of the stations at any desired measurement site. Since each station can collect large amounts of data during a given period of time, it was necessary to implement techniques such as Big Data in order to extract important information and to identify patterns from the data such as the areas having the highest concentration of gases and possible correlations with other variables such as local weather conditions. This information could be used to support the making of decisions that benefit the communities impacted by air pollution, for example the early triggering of bad air quality alarms or the development of policies to regulate industry operation that can potentially impact the health of neighboring communities. A pilot case study was implemented in the city of Floridablanca, Colombia, to demonstrate the monitoring of the emissions of hydrogen sulfide of a big wastewater processing plant.

Abstract:
The analysis and design methods used for turbomachinery components are mostly based on steady aerodynamics, neglecting the important unsteady nature of the flow field. An improvement in performance can however be achieved with a prior understanding, evaluation and modeling of the main unsteady loss sources generated in rotor/stator interactions, through new advanced experimental data coupled to systematic and controlled numerical simulations performed at the full unsteady level of approximation. But such calculations are even nowadays challenges to the CFD community, due to their high requirement in computer resources. To investigate the importance of unsteady loss mechanisms, a 1-1/2 axial turbine stage has been resolved at both quasi-steady and fully unsteady levels of approximation. In order to reduce the demand on computer resources, a scaling procedure can be applied to retrieve equal pitch distance on both sides of each rotor/stator interface. The space and time flow periodicity are then uncoupled and the unsteady flowfield may be resolved on a reduced number of blade passages per row without having to consider any time periodicity in the boundary treatment. The grid scaling however affects the turbine total pressure ratio and the position and strength of secondary flows, as the pitch-to-chord ratio is not kept constant. This effect is analyzed in the paper, with the objective to assess the associated approximation errors. Steady and unsteady numerical simulations are compared with the experimental data along three measuring stations placed downstream of each blade row. Even if steady results are in good agreement and allow capturing the main flow structures of the turbine stage, only the fully unsteady calculation resolves the complex loss mechanisms encountered mainly in the rotor and downstream stator components. These unsteady interactions are observed through time variations of the entropy, absolute flow angle and static pressure.

Abstract:
Edge detection plays an increasingly critical role in image process community, especially for moving object identification problems. For this case, the target object can be captured straightly via the edges beside which there is an obvious jump of grey value or texture. Nowadays, Canny operator has gained great popularity as it shows higher anti-noise performance and presents better detection accuracy in comparison with other edge detection operators like Robert’s, Sobel’s, Prewitt’s etc. However, the Gaussian filter associated with the classic Canny operator is sometimes too simple to decrease the all-type-noise. Additionally, in order to enhance the detection accuracy and lower the pseudo-edges detection ratio, two thresholds, high and low, are chosen artificially which have actually limited the adaptability of the algorithm. In this work, a compound filter, Gaussian-Median filter, is proposed to improve the smoothing effect. The self-adaptive multi-threshold Otsu algorithm is realized to determine the high/low threshold automatically according to the grey value statistic. Image moment method is conducted on basis of the detected moving object edges to locate the centroid and to compute the principal orientation. The experimental results based upon locating the edges of both static and moving objects proved the good robustness and the excellent accuracy of the proposed method.

"Experimental Investigation on the Dynamic Behaviour of a Dacron Graft Used for the Treatment of Descending Thoracic Aortic Aneurism."

Abstract:
The dynamic behavior of a woven Dacron graft, currently used in thoracic aortic reconstructions in the case of aneurysm or dissection, has been experimentally investigated for the first time. Dacron grafts are widely used in cardiovascular surgery to replace segments of diseased large blood vessels; however, scarce data are available about their durability. The dynamic modeling of such prostheses may fill this gap and may provide guidelines for the study of human aortic segments as well. Dynamic phenomena such as vibrations are being included among the most likely causes of important aortic pathologies, such as dissections and consequent ruptures. The compatibility of the dynamic behavior of Dacron grafts and human arteries seems a characteristic worthy of experimental investigation as well. For this reason, a cylindrical Dacron graft has been subjected to fixed boundary conditions and to a physiological value of static axial pre-stretch. A constant internal pressure, equal to the average value of the physiologic blood pressure, was exerted by a liquid mixture of suitable viscosity and density. A three-dimensional quasi-linear viscoelastic model was fitted onto the Dacron fabric by means of dedicated traction and relaxation tests. Forced linear and large-amplitude vibrations were imposed and measured. An identification tool recently developed by this research group is being used to study the change of the equivalent modal damping ratio with vibration amplitude during nonlinear vibrations. Furthermore, an ongoing study is revealing a dependence of dissipation on frequency that is coherent to the most common model for biological materials adopted by the medical community.
