Favela painting: building community, social change and emancipation through an OrgansparkZ/Art installation

For some time now, Brazilian favela dwellers have been constructing representations of joy, resourcefulness and creativity that the wider public sphere now associates with favela life. Through multiple bottom-up projects, they have managed to challenge deep-seated negative understandings of favela dwellers as inherently poor and violent. In this post, J. Miguel Imas discusses how the Favela Painting project has contributed to this endeavour through an OrgansparkZ/Art intervention, a collective art installation that acts as a vehicle for social change

An Indigenous Women Perspective of Work and Organisation: The Maya Way

Western literature in management/organisation studies focuses primarily on gender issues that affect inequalities experienced by women at work. Adopting, in some cases, critical and feminist theoretical positions, the gender debate unfolds questions on the prevailing male discourse that is dominant in management and business organisations. Most of these theoretical assumptions tend to influence, subsequently, the way in which we understand the experiences of women in the developing or under-developed world. That is, these theoretical positions occupy a privileged voice upon which to write, describe and analyse the experiences of women in contexts where these Western discourses seem either alien or simply do not apply. This raises important questions on how we come to understand, for instance, indigenous women organisations, from within the language and local cultural experience that these women have. However important and relevant this literature is (critical and feminist), less has been said on how women, in the context of indigenous communities and organisations outside the dominant Western discourse of management/organisation, act and enact their organisation and working practices. Indeed, recent interest in postcolonial studies leaves open a window to address how indigenous women organise their work and their lives, challenging prevailing views on the subject. We think there is a need here to give voice to marginalised indigenous women, who are unrepresented in these debates. In this way, we certainly believe, we can start thinking of a truly plurivocal way of understanding and representing organisation (studies) that embraces discourses and practices from the periphery of the global (corporate/academic) centre. Henceforth, our principal objective in this paper is to engage with indigenous women organisations in order to contribute to this debate from a postcolonial and local perspective to suggest alternatives to traditional views on the subject or feminist/critical assumptions that neglect these discourses. For this purpose, we have conducted critical ethnographic research with cooperatives in Guatemala. More specifically, we have engaged in dialogue with Maya co-operatives run by indigenous women in the Sololá Department of Guatemala. In the rest of the paper, we start with a review of feminist (organisational) theorising, transitioning to a discussion of the importance of a postcolonial critical feminist approach to organisation studies. We then describe our methodology and present our ethnographic work, which considers the issues raised in our theoretical discussion. We close the paper with some reflections on the significance our work has for organisation studies and the importance of incorporating the view of indigenous ‘Third World women’ to the field

Mirrors: \u27Bleeding\u27 the Creation of Alternative Organization through a Liberating Ideology of Transformative Humanism

In this paper, we propose a new way of explaining the everyday practices of communities who socially organize to create sustainable grass-roots engagement. We discuss how this collective engagement is based on principles and values of socio-economic engagement that are fundamentally different to those associated with capitalism. We theorise that these community engagements are sustained by an organizational ideology of \u27transformative humanism\u27 that is founded on an ongoing struggle for emancipation. Our perspective is constructed through a combination of Frantz Fanon\u27s ideas on humanism, Manfred Max-Neef\u27s barefoot economics, and Paulo Freire\u27s pedagogies of hope and transformation. We suggest that movements such as this embody alternative ways for disenfranchised individuals to shape grass-roots social transformation from within because they are based on an alternative system of beliefs. We present examples of grass-roots engagement in Argentina and South Africa to demonstrate how disenfranchised communities organize together through transformative humanism

Daya Penyebaran dan Derajat Kepekaan Sektor Pertanian dalam Pembangunan Ekonomi di Provinsi Jawa Tengah

This research aimed to analyze the power of dispersion and sensitivity of dispersion of the agricultural sector on the economic development of Central Java Province. This research used the data of Input and Output Table of Central Java in 2013. Data analysis method applied in this research is Input-Output analysis. The results showed that the agricultural sector represented by the livestock sector had ‘above average\u27 power of dispersion index of the overall index. Livestock sector was able to encourage the production growth in all sectors of the economy. On the other hand, the sensitivity of dispersion index of all agricultural sectors was lower than the average value of the overall index. This reflects the agricultural sector\u27s low sensitivity to the changes of the external aspects which results in the low forward linkage among the downstream sectors. In term of key sector identification, the agricultural sector as a whole was not classified in the priority sector I. However, the livestock subsector, representing the agricultural sector, was classified in the priority sector II on the economic development of Central Java Province

Route Towards a Label-free Optical Waveguide Sensing Platform Based on Lossy Mode Resonances

According to recent market studies of the North American company Allied Market Research, the field of photonic sensors is an emerging strategic field for the following years and it is expected to garner $18 billion by 2021. The integration of micro and nanofabrication technologies in the field of sensors has allowed the development of new technological concepts such as lab-on-a-chip, which have achieved extraordinary advances in terms of detection and applicability, for example in the field of biosensors. This continuous development has allowed that equipment consisting of many complex devices that occupied a whole room a few years ago, at present it is possible to handle them in the palm of the hand; that formerly long duration processes are carried out in a matter of milliseconds and that a technology previously dedicated solely to military or scientific uses is available to the vast majority of consumers. The adequate combination of micro and nanostructured coatings with optical fiber sensors has permitted us to develop novel sensing technologies, such as the first experimental demonstration of lossy mode resonances (LMRs) for sensing applications, with more than one hundred citations and related publications in high rank journals and top conferences. In fact, fiber optic LMR-based devices have been proven as devices with one of the highest sensitivity for refractometric applications. Refractive index sensitivity is an indirect and simple indicator of how sensitive the device is to chemical and biological species, topic where this proposal is focused. Consequently, the utilization of these devices for chemical and biosensing applications is a clear opportunity that could open novel and interesting research lines and applications as well as simplify current analytical methodologies. As a result, on the basis of our previous experience with LMR based sensors to attain very high sensitivities, the objective of this paper is presenting the route for the development of label-free optical waveguide sensing platform based on LMRs that enable to explore the limits of this technology for bio-chemosensing applications

Rheumatoid arthritis miRNA biomarker detection by means of LMR based fiber-optic biosensor

Development of miRNA optical biosensors for disease diagnosis and monitoring has acquired relevance in recent years, due to the clinical importance of miRNA and the inherent advantages of optical sensors. Here, we present the utilization of a fiber optic sensor based on Lossy Mode Resonance (LMR) for the detection of miRNA hsa-miR-223, a promising biomarker for the diagnosis of rheumatoid arthritis (RA).This research was funded by the Spanish Agencia Estatal de Investigación (AEI) (PID2019-106231RB-I00), the Public University of Navarra (PJUPNA26), and the Spanish Ministry of Universities (FPU18/03087). In addition, this project has received funding from the ATTRACT call financed by the European Union's Horizon 2020 research and innovation program under grant agreement No 777222

Carbon dots nanoparticles as an effective gate for PDT

The promising strategy for targeted cancer treatment is to employ light as an external activator of a drug accumulated in tumor tissue. This approach is so-called photodynamic therapy (PDT) and can be used for diagnostic purposes. A photosensitizer, molecular oxygen, and laser light are the three significant components of Type II PDT, and the mechanism is the catalysis of the production of reactive oxygen species that lead to the oxidative damage of cellular molecules inducing cancer cell death [1]. Fluorescent carbon dots (CDs), spherical nanoparticles with size < 10 nm that can function as bioimaging agents and photosensitizers, have demonstrated significant potential in cancer theranostics [2]. Here, we have created Nitrogen co-doped carbon dots (N-CDs) surface decorated with organometallics compound, based on the Ru complex (Ru@N-CDs) [3,4] that were active in inducing biomolecular changes in ovarian cancer cell line upon illumination. Upon illumination, the most significant structural changes occurred in ovarian cancer cells and were detected in the protein region; we postulate interference with signaling pathways involved in regulating cancer cell growth and tumor progression. However, the limitation of light is the depth of penetration through the tissues, which prevents significant therapeutic effects on deep tumors. A strategy to overcome this is to use optical fibers that have coatings fabricated from the N-CDs, thus developing a so-called lab-on fiber system. The light propagating through the fiber [4] can activate the overall coating on the optical fiber surface with the presence of Ru@N-CDs. We hypothesize that the activation by the light results in the locally increased ROS production combined with enhanced release of the Ru complex from the surface, similar to the Ru@TiO2 NCS [5]. Our preliminary results demonstrate a high potential of the lab-on-fiber system in therapy against ovarian cancer that can resist traditional chemotherapeutic approaches.IX International School and Conference on Photonics : PHOTONICA2023 : book of abstracts; August 28 - September 1, 2023; Belgrad

Data was presented descriptively. The result showed based on the first place of treatment, pattern of treatment seeking behavior were identified the most common one was using public hospital as the first step. Pattern of treatment seeking behavior of the patient\u27s care taker that injluenced decision making to take treatment alternatives included knowledge, attitude and practice about the caused, symptomp \u27s, virulence and transmission of dengue virus infection; the distanee to treatment places and family role (husband/wife) were important for caretakers to take into consideration when making treatment choices

Incidence and control of bovine gastrointestinal nematodes in the East of the Province of La Pampa, Argentina

A cross-sectional survey including 350 stocking farms and bovine establishments that operate the full cycle (FC) as well as fattening operations (IN) was carried out in the East of the Province of La Pampa to record cases of verminous gastroenteritis (VGE) as well as control and management practices applied by the farmers.Farms were stratified by herd size into three categories: more than 900 (G), 900-500 (M) and 500-300 (P) bovines. Samples from each category were collected at random. 33% of the farmers surveyed indicated that their animals had been affected by clinical cases of VGE with morbidity and mortality rates between 11.2% and 0.42%, respectively. More cases of VEG (P<0.004, X2 8.33) occurred in herds on FC establishments (37%) that on fattening farms (IN) (21%); the relative risk (RR) was 1.77 (95%; IC 1.18 – 2.74) but no differences were noted between categories. Ninety-four percent of the farmers use avermectins alone (AVM) (71%) or combined with benzimidazole (BZD, 20%) or levamisole (3%); 6% use BZD alone. The percentage of use of other drugs in addition to AVM increases (P<0.005, X2 7.80) with larger herds (G: 32%, M: 21%, P: 15%). Of the treatments, 95.2% include avermectins alone in injectable form (82.6%) or combined with oral (16.5%) or intraruminal (0.9%) forms. Approximately 2.42 treatments per year are performed and are more prevalent (P<0.01) in G and IN farms (2.7 treatments). 35% of the farmers deworm twice a year, in the fall (between March and July) and in late winter-spring (between August and October-), 16% deworm only once (between February and April) and 12% twice (between late summer and early winter). 18% of the farmers (G: 24%, M: 18%; P: 13%) prevent VGE losses by administering treatment at a specific time of the year. 60% of the farmers consult the veterinarian although only 29% perform an egg count (hpg) although differences (P<0.001) between herd sizes were noted: G: 41%, M: 26%; P 19%. 12% (FC 10%; IN 16%). 12% of the farmers (FC 10%; IN 16%) perform a follow-up of parasite infections with an egg count and administer treatment based on this monitoring and the recommendation of a veterinarian. 94% of those surveyed indicated that VGE alone (55%) or in conjunction with other pathologies were a major problem and 30% said it was the main health problem. The study shows the economic importance of GIPs for the competitiveness of the systems in the region. The use of a significant quantity of anthelmintics, mainly avermectins, and a low participation of veterinarians in planning the controls were observed. A trend indicating that large farms and fattening operations assign more importance to control, use of anthelmintics and participation of professionals was noted
