Industrial Districts and the City: Relationships in the Knowledge Age. Evidence from the Italian Case

The spatial implications of fordist and district-based patterns of development have had a profound effect on the debate about the role of the city. While the city is reputed to be the crucial provider of basic public goods within the fordist model, its role seems more nuanced, if not disputable, when the district model prevails. This disregard for the city is probably due (a) to the fact that the revival of the debate on marshallian districts has placed strong emphasis on the agglomeration economies internal to the districts themselves, while relatively omitting the urban ones, when not emphasising the burden of urban diseconomies; (b) to the countryside roots of most district pioneers. The quarrel was further fuelled with the advent of ICTs, the fragmentation of the productive processes and the possibility of displacing phases at a global level. The paper argues that this is only the early part of the history. The advent of ICTs has had not only functional although important consequences on the internal organisation of firms and industry and on economic geography as a whole; it has also, however, made innovation and knowledge ? rather than cost-saving policies ? the crucial drivers of the competitiveness of firms and local economic systems. The notion of knowledge has profoundly changed too, and the main change consists in the shift that is occurring from Learning I to Learning II, that is from the “production and accumulation†of knowledge according to pre-established codes, to its “generation and articulation†thanks to an endless reshaping of cognitive codes. On this prospect, while firms, places and regions are increasingly conceptualised as Learning II milieus, cities are proving to be a crucial and irreplaceable milieu for knowledge generation. As a consequence, it is becoming necessary to reassess the relationships between industry and the city. Within this new situation, industrial districts may suffer a severe condition of marginality from the central driver of knowledge generation, owing to their lack of internal competences in dialoguing with the city, and/or the lack of suitable mediators.

Environmental Innovations, Local Networks and Internationalization

This paper investigates the drivers of the environmental innovations (EI) introduced by firms in local production systems (LPS). The role of firm network relationships, agglomeration economies and internationalization strategies is analysed for a sample of 555 firms in the Emilia-Romagna region, North-East of Italy. Cooperating with ‘qualified’ local actors – i.e. universities and suppliers – is the most important driver of EI for most firms, along with their training policies and IT innovations. The role of agglomeration economies is less clear and seems to depend on the EI propensity of more locally oriented firms playing in district areas, which might even turn agglomeration into dis-economies. Networking effects and agglomeration economies are instead found to strongly promote the adoption of EI by multinational firms, thus highlighting the importance of local-global interactions. We provide some interesting findings for particular kinds of challenging EI in fields as CO2 abatement and ISO labelling, generally extending the analysis EI driver by joining local and international factors.Eco-Innovation, Foreign Ownership, Networking, District, Agglomeration Economics, Local Production Systems

A multimodal smartphone interface for active perception by visually impaired

The diffuse availability of mobile devices, such as smartphones and tablets, has the potential to bring substantial benefits to the people with sensory impairments. The solution proposed in this paper is part of an ongoing effort to create an accurate obstacle and hazard detector for the visually impaired, which is embedded in a hand-held device. In particular, it presents a proof of concept for a multimodal interface to control the orientation of a smartphone's camera, while being held by a person, using a combination of vocal messages, 3D sounds and vibrations. The solution, which is to be evaluated experimentally by users, will enable further research in the area of active vision with human-in-the-loop, with potential application to mobile assistive devices for indoor navigation of visually impaired people

Agglomeration economies, knowledge spillovers, technological diversity and spatial clustering of innovations.

This paper explores the spatial patterns of innovative activities from an empirical perspective and with reference to the Italian case. Using patent and other economic data at the NUTS 3 level (provinces), it borrows methodology and techniques from spatial statistics in order to analyse the way innovative and economic activities are arranged in space. Results show that innovative activities are considerably more spatially concentrated than production, but that there are also large differences across sectors in the spatial patterns of innovation. In mechanical engineering, industrial equipment and instruments sectors innovative activities tend to cluster around local systems of contiguous provinces, while in most chemical and electronic sectors innovative activities tend to concentrate in few metropolitan provinces surrounded by other non-innovative provinces. Regression analysis is also carried out to evaluate the impact of agglomeration economies, knowledge spillovers and technological diversity on the innovative performance of provinces.

Output Filter Aware Optimization of the Noise Shaping Properties of {\Delta}{\Sigma} Modulators via Semi-Definite Programming

The Noise Transfer Function (NTF) of {\Delta}{\Sigma} modulators is typically designed after the features of the input signal. We suggest that in many applications, and notably those involving D/D and D/A conversion or actuation, the NTF should instead be shaped after the properties of the output/reconstruction filter. To this aim, we propose a framework for optimal design based on the Kalman-Yakubovich-Popov (KYP) lemma and semi-definite programming. Some examples illustrate how in practical cases the proposed strategy can outperform more standard approaches.Comment: 14 pages, 18 figures, journal.

Subjective response to seated fore-and-aft direction whole-body vibration

Subjective response to seated, fore-and-aft direction, whole-body vibration of the type experienced in automobiles was investigated. Fore-and-aft acceleration was measured at the seat guide of a small automobile when driving over two representative road surfaces, and was replicated in a laboratory setting using a whole-body vibration test rig and rigid seat. A single 15-second section of each of the two acceleration time histories was band-pass filtered to the frequency interval from 0.5 to 50.5 Hz, and was used as a base stimulus. Thirteen test stimuli were then constructed for each base stimulus by rescaling to BS 6841 Wd frequency-weighted r.m.s. amplitudes from 0.01 to 0.86 m/s2. Two groups of 16 participants (8 male and 8 female in each case) rated the discomfort of the test stimuli. The first group was asked to use the psychophysical method of magnitude estimation while the second used a Borg CR-10 scale. The order of presentation of the test stimuli was fully randomised and each was repeated 3 times. For each group of participants, regression analysis was used to determine both the individual and the group mean Stevens’Power Law exponent describing the relationship between stimulus amplitude and subjective response. All mean power exponents were found to be less than unity, with the CR-10 scale having produced smaller exponents than magnitude estimation. The power exponents ranged from 0.66 to 0.91, corroborating the value of 0.84 obtainable from the guidelines of standard BS 6841.The results suggest that the numerical response scale provided in the BS 6841 guidelines is appropriate for use in the case of automobile fore-andaft vibration, but that the semantic labels under-represent the actual human subjective response in this direction. Psychophysical test method, vibration stimulus range and test participant gender were all found to affect the Stevens’ Power Law exponent achieved from subjective testing. Each factor may therefore require control when attempting to compare human responses to vibration originating from different automobiles
