In urban communities, infrastructures that support living are indispensable. There is increased interest in alternative ways of providing such support systems, including semi-autonomous infrastructures resulting from the self-organization of local actors. In this study, we analyze the emergence and management of such infrastructures in light of the theory of complex adaptive systems, within which they are called ‘inverse infrastructures’. Empirical evidence is drawn from the case of water cooperatives in the town of Ikaalinen, Finland. Our analysis shows that, with favorable preconditions in place, inverse infrastructures may contribute significantly to local infrastructure services and so also to the functioning of society.

Analizar el mapa de la conectividad en la Argentina contemporánea implica revisar las redes de infraestructura y servicios fijos y móviles existentes, su capilaridad, y la articulación de actores: los preponderantes telefónicos a escala nacional, las sociedades público-privadas nacional y provinciales, las 547 cooperativas de servicios públicos y TIC, además del millar y medio PyMEs de distribuidores de TV de pago y proveedores de Internet.
Uno de los mayores inconvenientes para el futuro cercano de operación de las cooperativas de servicios TIC y audiovisuales radica en no disponer de acceso a frecuencias para brindar servicios móviles. Aún mediante su despliegue territorial con capacidades y niveles de calidad competitivos respecto de otros prestadores con dominancia en su escala comercial, no pueden hasta el momento brindar servicios paquetizados más allá del triple play (telefonía e internet fijas y TV de pago).
Las cooperativas encontraron la fórmula de Operador Móvil Virtual (OMV) como única vía de acceso a la posibilidad de brindar telefonía y datos móviles para supervivir al desafío de la convergencia competitiva con los grandes operadores, aún desde una posición periférica. Un relevamiento de la Cátedra Libre Conectividad UNLP actualizado a abril de 2021, destaca que dentro de las licencias para OMV otorgadas por la autoridad de aplicación, 27 corresponden a personas jurídicas sin fines de lucro o estatales: 20 licencias están otorgadas a Cooperativas de diversas provincias del país, cuatro a Sociedades Estatales con Participación Estatal Mayoritaria, dos a Gobernaciones y otra a un municipio.
La mayoría de las licenciatarias cooperativas de OMV concurre al proyecto full OMV Imowi, articulado por la Cámara Argentina de Telecomunicaciones (CATEL), aunque también la federación FECOTEL planifica montar un OMV en el próximo quinquenio.
La ponencia en RedCom 2021, actualizá el escenario de despliegue, operación y nichos de usuarios y ciudadanía a incluir por los prestadores de la economía social, de cara a la conectividad y los servicios 5G, en tensión con los tres grandes operadores nacionales.

This study tries to examine the challenges faced by the consumer cooperatives in conducting its retail activities in Peninsular Malaysia. Very little research has been performed in this area, that the intention of this research is to provide an insight on the scenario that is happening surrounding this organization. Questionnaires were distributed using the simple random sampling to obtain the perception of respondents from cooperatives. Responses from a sample of 300 cooperatives were analyzed. The result has indicated that the top most challenges facing the cooperatives are (1) Financial, (2) Corporate Governance, (3) Members Involvement, (4) Marketing, (5) Supplier Relations, (6) Competitions, (7) Employee’s motivation. Some of the findings of this paper could be a proposal for those researchers who have the interests to go deeper to investigate in this area.

The breakthroughs in microbiology have allowed us to come to terms with the microbial resources present in culture collections and in natural environments. The challenge at present is to manage these microbial resources, particularly when one deals with open systems where the dynamics of microbial ecology are predominant. Hence, to properly address the aspects of Microbial Resource Management (MRM), one needs to handle the questions of who is there, who is doing what with whom and how can one adjust, control and/or steer these mixed cultures and communities. It is argued that microbial ecologists and environmental microbiologists need to address a new mind-set. The Beijerinck axioma that all microorganisms are everywhere should not be presumed to be generally valid. The Darwin based niche assembly concept needs to be supplemented with the neutral theory of Hubbell. The Pareto 80/20 principle is also applicable to the macro-economies of microbial communities. Finally, the concept of a “stable” microbial community should be replaced by that of a cooperative community continuum. Overall, MRM is at the basis of a number of new developments in domains such as environmental safety and health, renewable energy production, closing environmental cycles and providing new materials. Specific examples such as, for example, pro-active immuno-stimulation by means of drinking water, electro-microbiology, decreasing global warming by implementation of methanotrophs and generation of nano-biocatalysts are discussed.

In recent years, Multiple-Input Multiple-Output
(MIMO) systems have emerged as a most promising technology in these measures. MIMO
communication systems can be defined intuitively [GSS+03, PNG03] by considering that
multiple antennas are used at the transmitting end as well as at the receiving end.

Otras plataformas propone mirar en las periferias del ecosistema de medios en un contexto donde al menos dos condiciones se han modificado sustancialmente: la cuestión de la conectividad y su emergencia como núcleo esencial para el desarrollo de aspectos centrales de la vida pública y privada durante la pandemia pero además, en el marco de la post pandemia que empezamos a imaginar, y, la plataformización acelerada del trabajo, la educación, el entretenimiento, la información y de la mayor parte de las dimensiones de nuestras interacciones sociales.

This project work is aimed at showing the use of cooperative society as a measure to improving the economic activities of the society a case study of Eziniihitte LGA of Imo state. The objectives are geared towards evaluating the roles of cooperative societies in evaluating the lacks in the societies and providing the immediate solution and helping them improve by creating additional wealth to their pockets. Cooperatives are expected to serve its members by providing agricultural inputs, output marketing and mobilizing savings and providing credit services to their members. The literature review encompasses various literary works on the subject matter which affects and influences channels of distribution. The data for the study are gotten through questionnaires administered on sample size of five cooperative societies. The data are tabulated and analyzed. Also two hypotheses are formulated and tested statistically to confirm or reject the hypotheses. It is established in hypothesis one that one of the major reasons for joining cooperative societies depends on their insufficient financial positions individually. The second hypothesis also establish that cooperatives societies have much effect on its members’ economic welfare. The project on completion will bring to open the importance of cooperative societies and how their activities uplifts the economic activities of their members.

Abstract
Grice’s theory of implicature has been considered ethnocentric, but this paper will argue that it is highly relevant to intercultural analysis. The Principle of Cooperation, and its subordinate maxims, focus on the rationality of discourse, but Grice also includes linguistic and nonlinguistic context, conventional meaning and “other items of background knowledge” in the inferential process. This notion of background knowledge is radically refined by Sperber and Wilson. Within a theory of relevance, interlocutors share only some contextual clues in a “mutual cognitive environment”. In intercultural negotiation a high level of awareness of assumptions about what is “mutually manifest” is of central importance to performance.
Teachers of intercultural communication skills attempt to establish a balance between providing meaningful practice and a useful rationale for improving theoretical awareness of the inferential process. This paper uses recordings of a classroom simulation involving foreign and Japanese students of intercultural communication taking part in a traffic accident insurance negotiation. Two data extracts are examined in detail, in which the failure by a foreign student to recognize radically different background assumptions had a decisive negative impact on his ability to negotiate, but a positive impact on his ability to analyse his own intercultural performance.

The four-page chapter is a lesson plan for encouraging students to thank each other and to use other social skills, as part of an overall attempt to create a cooperative classroom environment. The chapter begins with a story about an extensive reading lesson in which students collaborated in groups of two. At the end of the lesson, the teacher asked students to thank their partner, but many students did not. The lesson plan then presents a generalizable procedure for encouraging expressions of gratitude and other social skills. The chapter ends with a reflection on the importance of social skills in learning and in life generally.

Abstract A distributed estimation algorithm for sensor networks is proposed. A noisy time-varying signal is jointly tracked by a network of sensor nodes, in which each node computes its estimate as a weighted sum of its own and its neighbors&amp;amp;amp;amp;amp;amp;#x27; measurements and estimates. The weights are adaptively updated to minimize the variance of the estimation error. Both estimation and the parameter optimization is distributed; no central coordination of the nodes is required. An upper bound of the error variance in each node is derived. This ...

Pese a la importancia creciente de las mujeres rurales en los ámbitos productivo y reproductivo y a su participación cada vez más visible en el espacio público, las políticas y programas oficiales para ellas están ancladas en una representación femenina que corresponde a una “vieja ruralidad”, que continúa situándolas en las funciones maternas, maritales y domésticas; pensándolas como mediadoras de políticas asistenciales y receptoras de subsidios para la familia, sin preguntarse por sus propias necesidades o aspiraciones; o destinándoles recursos para proyectos productivos marginales, que no reconocen su relevante papel en la economía familiar ni los cambios de género que están ocurriendo en el medio rural.
Este libro se propone reflexionar acerca de estos problemas que tienen raíces históricas en el agro latinoamericano y visibilizar las diversas labores que cumplen las mujeres en la organización de la producción familiar; su trabajo en las producciones regionales; su participación en los emprendimientos de economía solidaria, movimientos agraristas y en proyectos de desarrollo sostenible; las políticas dirigidas conocer o mejorar sus derechos, condiciones de vida y de trabajo. El propósito último es debatir y analizar los cambios y permanencias, diferencias y similitudes en la situación de las mujeres rurales de América Latina.

Social punishment has been suggested as a key approach to ensuring high levels of cooperation and norm compliance in one-shot interactions. However, it has been shown that it only works when punishment is highly cost-efficient. On the other hand, signalling retribution hearkens back to medieval sovereignty, insofar as the very word for gallows in French stems from the Latin word for power and serves as a grim symbol of the ruthlessness of high justice. Here we introduce the mechanism of signalling an act of punishment and a special type of defector emerges, one who can recognise this signal and avoid punishment by way of fear. We perform extensive agent-based simulations so as to confirm and expand our understanding of the external factors that influence the success of social punishment. We show that our suggested mechanism serves as a catalyst for cooperation, even when signalling and punishment are very costly. We observe the preventive nature of advertising retributive acts and w...

Recently, cooperative routing in wireless networks has gained much interest due to its ability to exploit the broadcast nature of the wireless medium in designing power-efficient routing algorithms. Most of the existing cooperation-based routing algorithms are implemented by finding a shortest-path route first. As such, these routing algorithms do not fully exploit the merits of cooperative communications at the physical layer. In this paper, we propose a cooperation-based routing algorithm, namely, minimum power cooperative routing (MPCR) algorithm, which makes full use of the cooperative communications while constructing the minimum-power route. The MPCR algorithm constructs the minimum-power route as a cascade of the minimum-power single-relay building blocks from the source to the destination. Hence, any distributed shortest-path algorithm can be utilized to find the optimal route with polynomial complexity, while guaranteeing certain throughput. We show that the MPCR algorithm can achieve power saving of 57.36% compared to the conventional shortest-path routing algorithms. Furthermore, the MPCR algorithm can achieve power saving of 37.64% compared to the existing cooperative routing algorithms, in which the selected routes are constructed based on the noncooperative routes.

Mezcal is an alcoholic beverage produced only in selected regions of Mexico under appellation of origin status from the Word Intellectual Property Organization. While it has been produced in Mexico for many centuries, mezcalâ€™s appellation of origin was only granted in 1995. Therefore efforts to produce and market it as a premium product have a relatively short history. This case

Workers' buyout (WBOs) are emerging during the present economic crisis as an alternative tool to maintain employment and production. In Italy, in the last thirty years, 258 cases have been recorded. What are their general characteristics? Why do WBOs develop and who are the main sponsors and financing tools? The present analysis aims at defining the phenomenon and the enabling environment. Moreover, primary sources collected from different actors will explain how WBOs have developed and thrived across Italy saving jobs and productive capacity.

One of the most efficient methods of exploiting space diversity for portable wireless devices is cooperative communication utilizing space-time block codes. In cooperative communication, users besides communicating their own information, also relay the information of other users. In this paper we investigate a scheme where cooperation is achieved using two methods, namely, distributed space-time coding and network coding. Two cooperating users utilize Alamouti space time code for inter user cooperation and in addition utilize a third relay which performs network coding. The third relay does not have any of its information to be sent. In this paper we propose a scheme utilizing convolutional code based network coding, instead of conventional XOR based network code and utilize iterative joint networkchannel decoder for efficient decoding. Extrinsic information transfer (EXIT) chart analysis is performed to investigate the convergence property of the proposed decoder.

Future generations of cellular communications requires higher data rates and a more reliable
transmission link with the growth of multimedia services, while keeping satisfactory quality of service, .
MIMO antenna systems have been considered as an efficient approach to address these demands by
offering significant multiplexing and diversity gains over single antenna systems without increasing
bandwidth and power. Although MIMO systems can unfold their huge benefit in cellular base stations,
but they may face limitations when it comes to their deployment in mobile handsets.
To overcome this drawback, relays (fixed or mobile terminals) can cooperate to improve the overall
system performance in cellular networks. Cooperative communications can efficiently combat the severity
of fading and shadowing through the assistance of relays. It has been found that using relays the capacity
and coverage of cellular networks can be extended without increasing mobile transmit power or
demanding extra bandwidth.

This paper presents Incremental relay-based Co-
CEStat protocol forWireless Body Area Networks (InCo-CEStat).
This protocol is proposed to enhance the performance of Cooper-
ative Critical data transmission in Emergency for Static Wireless
Body Area Networks (Co-CEStat) and Advanced Co-CEStat
(ACo-CEStat). Proposed protocol utilizes the merits of both direct
and cooperative transmission to achieve reliable and quick data
delivery and greater network stability period. Incremental relay-
based cooperation is utilized to improve energy efficiency of
the network. At relays, Detect-and-Forward (DF) technique is
used, whereas, selection combining technique is utilized at sink.
Simulation results are obtained in MATLAB in which proposed
protocol is compared with ACo-CEStat and Co-CEStat protocols.
Simulations show that InCo-CEStat has 37% and 58 % more
stability period than ACo-CEStat and Co-CEStat. InCo-CEStat
also achieved 51% and 79% higher throughput than that of
compared protocols

A social dilemma is a circumstance in which each of an aggregate of people must make an individual decision whether to acquire a short-term benefit for themselves or to forego some of that benefit for the long-term benefit of the aggregate. The intent of this essay is to describe how communication; in terms of both the opportunity to talk and the content of what is said; interacts with other “cooperative mechanisms” – group identity; reciprocity and equity norms; and trust and trustworthiness – to largely determine individual cooperation versus defection. Two variables with relatively complex impacts on the cooperative mechanisms – social value orientation and group size – are also discussed. A model and set of propositions relating these variables are also included; and areas for further are explored.

It is usually thought that only one being can be all-knowing, all-powerful, and all-loving. Challenging this monotheist conviction, I propose a universe ruled by two deities: ‘day shift God’ oversees the events that occur while the sun is up, whereas ‘night shift God’ oversees the events that occur while the sun is down. I survey objections to this proposal and conclude that the real obstacle is not an argument, but an aesthetic preference.

The biggest advantage of building “intelligence” into a sensor is that the sensor can process data before sending them to a data consumer. The kind of processing that is often needed is to aggregate the data into a more compact representation called an aggregate, and send the aggregate to the data consumer instead. The main security challenges to such a process are (1) to prevent Byzantine-corrupted data from rendering the final aggregate totally meaningless and (2) to provide end-to-end confidentiality between the data providers and the data consumer. This chapter surveys the state of the art in techniques for addressing these challenges.

In this paper, the application of simultaneous wireless information and power transfer (SWIPT) to non-orthogonal multiple access (NOMA) networks in which users are spatially randomly located is investigated. A new cooperative SWIPT NOMA protocol is proposed, in which near NOMA users that are close to the source act as energy harvesting relays to help far NOMA users. Since the locations of users have a significant impact on the performance, three user selection schemes based on the user distances from the base station are proposed. To characterize the performance of the proposed selection schemes, closed-form expressions for the outage probability and system throughput are derived. These analytical results demonstrate that the use of SWIPT will not jeopardize the diversity gain compared to the conventional NOMA. The proposed results confirm that the opportunistic use of node locations for user selection can achieve low outage probability and deliver superior throughput
in comparison to the random selection scheme.
