Joint Observation of the Galactic Center with MAGIC and CTA-LST-1

MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes (IACTs), designed to detect very-high-energy gamma rays, and is operating in stereoscopic mode since 2009 at the Observatorio del Roque de Los Muchachos in La Palma, Spain. In 2018, the prototype IACT of the Large-Sized Telescope (LST-1) for the Cherenkov Telescope Array, a next-generation ground-based gamma-ray observatory, was inaugurated at the same site, at a distance of approximately 100 meters from the MAGIC telescopes. Using joint observations between MAGIC and LST-1, we developed a dedicated analysis pipeline and established the threefold telescope system via software, achieving the highest sensitivity in the northern hemisphere. Based on this enhanced performance, MAGIC and LST-1 have been jointly and regularly observing the Galactic Center, a region of paramount importance and complexity for IACTs. In particular, the gamma-ray emission from the dynamical center of the Milky Way is under debate. Although previous measurements suggested that a supermassive black hole Sagittarius A* plays a primary role, its radiation mechanism remains unclear, mainly due to limited angular resolution and sensitivity. The enhanced sensitivity in our novel approach is thus expected to provide new insights into the question. We here present the current status of the data analysis for the Galactic Center joint MAGIC and LST-1 observations

Conflicto educativo entre misioneros salesianos y shuar en la provincia de Morona Santiago

La problem??tica planteada, pone de manifiesto un conflicto entre algunos Shuar y los misioneros por la gesti??n de la instituci??n educativa. Es importante comprender que la educaci??n es el n??cleo esencial de la evangelizaci??n misionera salesiana en el siglo XX y XXI. En el conflicto podemos encontrar actores heterog??neos en sus propuestas como: misioneros, docentes y padres de familia. Este conflicto nos lleva a problematizar cual es el papel de las congregaciones religiosas cat??licas en la configuraci??n de las pol??ticas educativas y culturales dentro de la sociedad Shuar. Una de las ciencias dedicadas a la relaci??n de las empresas misioneras y los pueblos ind??genas es la antropolog??a de la misiones. Utilic?? el an??lisis que la Antropolog??a de las misiones realiza de las actividades misioneras dentro de sociedades ind??genas, con la finalidad de mostrar la complejidad del conflicto educativo en Bomboiza

Dominance Effects from Local Competitors: Setting Institutional Parameters for Employment Relations in Multinational Subsidiaries; a Case from the Spanish Supermarket Sector

Dominance effects are normally associated with multinational corporations (MNCs). However, we argue that a strong local competitor can create 'dominance effects' setting the institutional parameters for employment relations in multinational subsidiaries. Moreover such an effect can be persistent. In this case the Spanish-owned El Corte Inglés (ECI) used its power and influence to establish an employer's federation and two 'yellow unions'. These yellow unions infiltrated the French-owned MNC Carrefour and most of the Spanish supermarket sector by the early 1980s and continue to dominate collective bargaining rounds and works council elections, marginalizing the main independent trade unions. This has resulted in poor pay and working conditions and a lack of effective employee representation across most of the Spanish supermarket sector. The fact that Carrefour established an international framework agreement to observe union rights in 2001 has as yet not changed this situation.

Between Local Interests and International Solidarity: Negotiating Restructuring at General Motors Europe

At no other firm has transnational worker cooperation been taken further than at General Motors Europe. Worker representatives engaged in European wide mobilization, strikes, and collective bargaining, with the aim of “sharing the pain” of concessions and preventing plant closures. We argue that this is a case of identity work, a deliberate shift in the ideational underpinnings of union strategy, orchestrated by the European Works Council. While trade union strategy was subject to the reshaping of interests due to the objective facts of corporate restructuring, it was also subject to an additional subjective and internal political process of identity work
