Big stories, small towns: Banlung, Ratanakiri, Cambodia

Big Stories: Banlung was an experiment in participatory media interfacing with a global platform for showcasing community stories in a development setting, coupled with a detailed review (in Potter, 2014). The project sought to work with local communities and people to highlight stories of change in the area around Banlung and the impact on ethnic minority groups in terms of losing land, language and culture. The work was also an attempt to add to both the practice and literature of participatory processes in the field of Communication for Development which many (e.g. Lie and Mandler, 2009) observe is under-reviewed. The work was produced in collaboration between Australian and Cambodian filmmakers, two local content producers from Tampuon and Kreung ethnic minorities, two Tampuon communities and a community based NGO Non Timber Forest Products. We addressed issues of how Tampuon communities were seeking to sustain their community in the face of change. 27 short documentaries were produced and multiple other media including photo essays and a standalone website on the Big Stories, Small Towns platform: http://bigstories.com.au/towns/banlun

The White Building

The White Building project was a multi-year participatory transmedia project using art as a mechanism for community building and organising in the White Building in Phnom Penh, Cambodia. The White Building in central Phnom Penh was built in 1963 as part of a modernist vision of social housing for artists and performers. Following the trauma of the Khmer Rouge, where the city was emptied and an estimated ninety percent of Cambodia’s artists were killed, the intervening Vietnamese-backed government sought to repopulate the building with an invitation to surviving artists to return. In recent years, largely due to government neglect, the building has fallen into disrepair and was demolished in June 2017. However, behind the fading facade and dilapidated infrastructure there was a complex community of over three thousand people including artists, musicians, community activists and everyday city dwellers. This research project archives and explores the role of recent media, art and creative community projects to document the everyday lives of the Building's inhabitants as both a means of resistance and to enable critical reflexivity among participants. The key question posed at the outset of development of the programs was “can localised creative art and media programs amplify the lived experience of a community and positively impact internal and external perception, identification and position?” To address this question a number of initiatives across a variety of mediums and media platforms were developed. This included development of the Aziza Film School, weekly art, photography, digital storytelling and community organising programs, events and exhibitions in the White Building showcasing creative works by residents for both internal and external audiences, partnership with local groups such as Sa Sa Art Projects who ran a gallery space and artist in residency program in the Building and fostering the development of the White Building Collective - a group of residents and students at the film school who have created high impact films, photography and online works including the Humans of Phnom Penh series. And in partnership with Sa Sa Art Projects the development of festivals, screenings and exhibitions showcasing the work of residents to the broader community and the creation of a community library and archive and the online archive of whitebuilding.org. Through this diverse range of initiatives, there was a desire to not only celebrate and document the living memory of this unique community, but to push back against government and property developers' interest in the site. The research documents how the dominant discursive acts of the more powerful can be challenged through the expression of the 'lived' and the elevation of everyday life. And that the very perception of the space and the sense of place was (re)produced through these interactions across these new and diverse mediascapes resulting in increased collective identification and action

Experimental cross-contamination of chicken salad with Salmonella enterica serovars Typhimurium and London during food preparation in Cambodian households

Non-typhoidal Salmonellae are common foodborne pathogens that can cause gastroenteritis and other illnesses in people. This is the first study to assess the transfer of Salmonella enterica from raw chicken carcasses to ready-to-eat chicken salad in Cambodia. Twelve focus group discussions in four Cambodian provinces collected information on typical household ways of preparing salad. The results informed four laboratory experiments that mimicked household practices, using chicken carcasses inoculated with Salmonella. We developed four scenarios encompassing the range of practices, varying by order of washing (chicken or vegetables first) and change of chopping utensils (same utensils or different). Even though raw carcasses were washed twice, Salmonella was isolated from 32 out of 36 chicken samples (88.9%, 95% CI: 73.0–96.4) and two out of 18 vegetable samples (11.1%, 95% CI: 1.9–36.1). Salmonella was detected on cutting boards (66.7%), knives (50.0%) and hands (22.2%) after one wash; cross-contamination was significantly higher on cutting boards than on knives or hands (p-valu

Oriented Algebras and the Hochschild Cohomology Group

Koam and Pirashivili developed the equivariant version of Hochschild cohomology by mixing the standard chain complexes computing group with associative algebra cohomologies to obtain the bicomplex C ˜ G * ( A , X ). In this paper, we form a new bicomplex F ˘ G * ( A , X ) by deleting the first column and the first row and reindexing. We show that H ˘ G 1 ( A , X ) classifies the singular extensions of oriented algebras

Equivariant Hochschild Cohomology

In this thesis our goal is to develop the equivariant version of Hochschild cohomology. In the equivariant world there is given a group G which acts on objects. First naive object which can be considered is a G-algebra, that is, an associative algebra A on which G acts via algebra automorphisms. In our work we consider two more general situations. In the first case we develop a cohomology theory for oriented algebras and in the second case we develop a cohomology theory for Green functors

Radio Number Associated with Zero Divisor Graph

Radio antennas use different frequency bands of Electromagnetic (EM) Spectrum for switching signals in the forms of radio waves. Regulatory authorities issue a unique number (unique identifying call sign) to each radio center, that must be used in all transmissions. Each radio center propagates channels to the two nearer radio centers so they must use distinctive numbers to avoid interruption. The task of effectively apportioning channels to transmitters is known as the Channel Assignment (CA) problem. CA Problem is discussed under the topic of graph coloring by mathematicians. The radio number of a graph can be used in many parts of the field communication. In this paper, we determined the radio number of zero-divisor graphs Γ(Zp2×Zq2) for p,q prime numbers

Multi-Criteria Decision-Making under <i>m</i>HF ELECTRE-I and H<i>m</i>F ELECTRE-I

In a few years, hesitant fuzzy sets (HFSs) have had an impact on several different areas of decision science. However, a number of researches have utilized the Elimination and choice translating reality (ELECTRE) methods to determine the multi-criteria decision-making (MCDM) problems with hesitant information. The aim of this research article is to develop new multi-criteria group decision-making (MCGDM) methods, such as the m-polar hesitant fuzzy ELECTRE-I (mHF ELECTRE-I) method and hesitant m-polar fuzzy ELECTRE-I (HmF ELECTRE-I) method. Proposed MCGDM techniques based on the hybrid models, m-polar hesitant fuzzy sets (mHFS-sets) and hesitant m-polar fuzzy sets (HmF-sets), which are the natural generalizations of HFSs and m-polar fuzzy sets (mF sets). These models enable us to deal with multipolar information under hesitancy. We use the proposed methods to deal the complex problems in which the membership degree of an element of given set uses the m different numeric and fuzzy values, to rank all the alternatives and to determine the best alternative. We present two practical examples that illustrate the procedure of the proposed methods. We also discuss the differences and comparative analysis of the proposed methods. Finally, we develop an algorithm that implements our decision-making procedures by using computer programming

Group Decision-Making Based on <i>m</i>-Polar Fuzzy Linguistic TOPSIS Method

The fuzzy linguistic approach provides favorable outputs in several areas, whose description is relatively qualitative. The encouragement for the utilization of sentences or words instead of numbers is that linguistic characterizations or classifications are usually less absolute than algebraic or arithmetical ones. In this research article, we animate the m-polar fuzzy (mF) linguistic approach and elaborate it with real life examples and tabular representation to develop the affluence of linguistic variables based on mF approach. As an extension of the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method, we develop an m-polar fuzzy linguistic TOPSIS approach for multi-criteria group decision-making (MCGDM). It is used to evaluate the best alternative, to get more authentic and comparable results and to handle the real life problems of having multi-polar information in terms of linguistic variables and values. In this approach decision-makers contribute their estimations in the form of linguistic term sets. To show the efficiency and compatibility of the proposed approach, we compare it with the m-polar fuzzy linguistic ELECTRE-I (Elimination and Choice Translating Reality) approach. Finally, we draw a flow chart of our proposed approach as an algorithm and generate a computer programming code
