Las ánforas de Brindisi en Hispania Citerior. Pautas de distribución y consumo
2017
La presencia del ejército romano republicano en la Hispania Citerior ha sido difícil de reconocer en el pasado debido al error en la interpretación de algunos yacimientos y la falta de investigación sobre el tema. En los últimos años, se han realizado nuevas investigaciones sobre yacimientos romanos republicanos identificando pequeñas fortificaciones militares y asentamientos civiles itálicos relacionados con el ejército. Uno de los fósiles directores presentes en todos estos yacimientos es la cerámica itálica tanto fina como común y las ánforas. Precisamente, las ánforas de la Apulia constituyen uno de los fósiles directores poco estudiados; este artículo pretende llenar este vacío y mostr…
Late Republican Amphora Trade in Malaca: Imports from Beatas Street at the Corner of Ramón Franquelo (Málaga, Spain)
2018
Se presenta un estudio tipológico, ceramológico y cuantitativo del conjunto anfórico procedente de la intervención realizada en la calle Beatas-esquina Ramón Franquelo en 1997. El yacimiento posee evidencias de ocupación durante el Alto y Bajo Imperio, pero sin duda, destaca la fase tardopúnica o romano-republicana, en la que junto a la presencia de un espacio funerario, se registraron depósitos con una gran cantidad de material anfórico, que hemos datado en torno al segundo cuarto del s. I a.C. Es resaltable la importante presencia de importaciones vinarias itálicas, pero también una abundante llegada de aceite de fuera de la península ibérica, como testimonian las ánforas Africanas Antigu…
Domestic Policies in Self-Enforcing Trade Agreements
2012
If all cross-country externalities travel through the terms-of-trade, efficient trade agreements target the terms-of-trade but ignore domestic policies. This argument has been advanced by prominent studies on trade agreements. The present paper shows that its logic fails if production possibilities are intertemporally linked -- for example, under dynamic factor accumulation. In this case, past policies shape current production possibilities and thus affect defection temptations. Therefore, self-enforcing trade agreements that leave the choice of domestic policies to individual countries risk that countries abandon the zone of voluntarily cooperation while optimizing their policies. Conseque…
La questione dell’autorizzazione ministeriale per le associazioni sindacali dei militari
2021
In according of CEDU in Italy trade union freedom is a right also recognized to members of the Armed Forces, but subject to limitations due to the functional aspect of the tasks institutional attributed. The peculiarity of the military organization reverberates in working relationships e gives trade union activity a special characterization with respect to the framework of trade union rights common. From the point of view of the specialty, the question of the preventive ministerial scrutiny of the legitimacy to carry out this activity which, according to the Council of State, stands out for a high degree of discretion. This statement leads us to believe that the establishment of an associat…
L’art. 28 dello Statuto e le trasformazioni del lavoro: cinquant’anni portati bene, ma non troppo
2020
L’art. 28 dello Statuto dei lavoratori ha attraversato un cinquantennio di storia del conflitto sindacale italiano. Si tratta di un rimedio ancora attuale, che necessità di un intervento manutentivo alla luce delle trasformazioni del diritto del lavoro. Partendo dalla validità del modello normativo, il saggio individua le criticità per il legislatore in una prospettiva de jure condendo.
An ANN model to correlate roughness and structural performance in asphalt pavements
2017
Abstract In this paper, using a large database from the Long Term Pavement Performance program, the authors developed an Artificial Neural Network (ANN) to estimate the structural performance of asphalt pavements from roughness data. Considering advantages of modern high-performance survey devices in the acquisition of road pavement functional parameters, it would be of practical significance if the structural state of a pavement could be estimated from its functional conditions. To differentiate various road section conditions, several significant input parameters, related to traffic, weather, and structural aspects, have been included in the analysis. The results are very interesting and …
Determinants and efficiency of Pakistan's chemical products' exports: An application of stochastic frontier gravity model.
2019
The estimation of efficiency of industry-specific exports is very important to find exports' gap and to frame exports promotion policy for targeted industry. This study attempts to investigate the main determinants of chemical products' exports of Pakistan with 62 trading partners by applying Stochastic Frontier Analysis (SFA) on an augmented gravity model for a period 1995-2015. The results corroborate that chemical products' exports follow gravity patterns. This study finds a negative and significant impact of import tariff on exports of chemical products while the positive impact of devaluation has been observed. Further, the estimations also take into account the impact of Preferential …
Microstructural Study of Asphalt Mixture Containing Reclaimed Material
2012
In this paper mixing of reclaimed material with virgin asphalt material has been studied non-destructively. Specimens prepared with virgin asphalt mix and with asphalt mix containing reclaimed material were scanned in X-ray Computed tomography (CT). The obtained Images were analysed for particles and pores (air voids) distribution. All the specimens were also tested in compression test and X-ray scanned while testing. It was found that distribution of reclaimed is not uniform through the samples. There is no considerable effect of increasing the mixing time on particles' distribution. Similar trend of increase in air voids (cracks) with the increase in load was found for both virgin mix and…
Evaluation of dry asphalt rubber concrete in railway sub-ballast using the four point bending test
2016
The study of bituminous mixes can be related to tyre rubber material recycling. Encouraging scrap tyre disposal and cutting down on pit employment are the environmental aims. In the field of railways, technological processes involved in the use of crumb rubber are the wet-dry processes. In the mechanical characterisation of the asphalt concrete in terms of both the fatigue resista recycled waste tires nce and the stiffness modulus it is necessary to use a design method for the sub-ballast railway material, even more so if the asphalt concrete investigated is an innovative material such as a dry asphalt rubber concrete (DARC) (i.e. a bituminous mixture with crumb rubber formed by a dry proce…
Free Fields for Chiral 2D Dilaton Gravity
1998
We give an explicit canonical transformation which transforms a generic chiral 2D dilaton gravity model into a free field theory.
