On Alternating Non-Context-Free Grammars

We study several extensions of the notion of alternation from context-free grammars to context-sensitive and arbitrary phrase-structure grammars. Thereby new grammatical characterizations are obtained for the class of languages that are accepted by alternating pushdown automata.

El problema demográfico en Japón, y la incidencia en las políticas concernientes a la seguridad social del gobierno japonés. (periodo 2007 a 2012)

El interés de este estudio de caso es entender la incidencia de los problemas demográficos de Japón sobre las políticas concernientes al Sistema de Seguridad Social Japonés, así como la viabilidad de estas políticas ante la muy difícil situación que existe. Observando cómo los problemas demográficos han afectado el Sistema de Seguridad Social por medio de estudios demográficos del pasado y actuales, además de proyecciones poblacionales a futuro, para así poder comparar los mecanismos implementadas por el Gobierno Japonés y los resultados obtenidos con las necesidades reales del Sistema de Seguridad Social Japonés, abriendo la posibilidad de entender profundamente las debilidades y las posibles soluciones al problema que enfrenta este sistema.

A Transatlantic Trade and Investment Partnership Agreement: Implications for Swiss Agriculture

To say that regionalism is gaining momentum has become an understatement. To mourn the lack of progress in multilateral trade rule-making is a commonplace in the discourse of politicians regretting the WTO negotiation standstill, and of “know-what-to-do” academics. The real problem is the uneven level-playing field resulting from increasing differences of rules and obligations. The Transatlantic Trade and Investment Partnership Agreement (TTIP) is a very ambitious project. WTI studies in 2014 have shown that the implications for Switzerland could be enormous. But even the combined market power of the two TTIP participants – the EU and the USA – will not level the playing field impairing the regulatory framework, and the market access barriers for trade in agriculture. Such differences will remain in three areas which, incidentally, are also vital for a global response to the food security challenge to feed 9 billion people before the year 2050: market access, non-tariff barriers, and trade-distorting domestic support programmes. This means that without multilateral progress the TTIP and other so-called mega-regionals, if successfully concluded, will exacerbate rather than lessen trade distortions. While this makes farmers in rich countries safer from competition, competitive production in all countries will be hampered. Consequently, and notwithstanding the many affirmations to the contrary, farm policies worldwide will continue to only address farmer security without increasing global food security. What are the implications of the TTIP for Swiss agriculture? This article, commissioned by Waseda University in Tokyo, finds that the failure to achieve further reforms – including a number of areas where earlier reforms have been reversed – is presenting Switzerland and Swiss agriculture with a terrible dilemma in the eventuality of a successful conclusion of the TTIP. If Swiss farm production is to survive for more than another generation, continuous reform efforts are required, and over-reliance on the traditional instruments of border protection and product support is to be avoided. Without a substantial TTIP obliging Switzerland to follow suit, autonomous reforms will remain extremely fragile.

Oxygen isotopes and hydrocarbon composition of gas hydrate and hydrate water from ODP Leg 165 sites

Ocean Drilling Program (ODP) Leg 164 recovered a number of large solid gas hydrate from Sites 994, 996, and 997 on the Blake Ridge. Sites 994 and 997 samples, either nodular or thick massive pieces, were subjected to laboratory analysis and measurements to determine the structure, molecular and isotopic composition, thermal conductivity, and equilibrium dissociation conditions. X-ray computed tomography (CT) imagery, X-ray diffraction, nuclear magnetic resonance (NMR), and Raman spectroscopy have revealed that the gas hydrates recovered from the Blake Ridge are nearly 100% methane gas hydrate of Structure I, cubic with a lattice constant of a = 11.95 ± 0.05 angström, and a molar ratio of water to gas (hydration number) of 6.2. The d18O of water is 2.67 per mil to 3.51 per mil SMOW, which is 3.5-4.0 heavier than the ambient interstitial waters. The d13C and dD of methane are -66 per mil to -70 per mil and -201 per mil to -206 per mil, respectively, suggesting that the methane was generated through bacterial CO2 reduction. Thermal conductivity values of the Blake Ridge hydrates range from 0.3 to 0.5 W/(m K). Equilibrium dissociation experiments indicate that the three-phase equilibrium for the specimen is 3.27 MPa at 274.7 K. This is almost identical to that of synthetic pure methane hydrate in freshwater.
