Absorptive Capacity In Service Innovation: the Role of IT Capabilities
No full textThis working paper sets up the basis for investigating the role of IT capabilities in the context of large and distributed service organizations. The idea grounded in this article resides in the possibility that absorptive capacity has an impact on service innovation. Addressing some theories on absorptive capacity and on service innovation we provide a brief insight on the importance that IT skills and capabilities can have on service innovation in large organization which are widespread distributed in different geographical location
The institutionalization of project management: an analysis of the actors, strategies and paths that lead to the professionalization of a new discipline
No full textModern economy, especially over the last 20 years, and the continuous development of new technologies brought to the modification of society and the way people work. As a result, a number of new professional figures emerged and embarked on what has been historically termed a professional project. The focus of this thesis is on one of those new expert occupations: project management (PM). As new expert occupation, being hampered by multiple players with contrasting interests, it is forced to develop its professional projects in a new way differently from old and traditional, professions. Professionalization is then seen as the spatially and temporally contingent outcome of the negotiations between different actors (i.e.: professional associations, big corporations, State, universities), each with their own objectives, interests, resources, and capabilities. The used methodology is a qualitative case study made up of semi-structured interviews and archival data (retrieved trough websites, journals and newspapers) with all above mentioned actors. Thus, the methodological unit of analysis is Italian PM field. Setting the Italian field as a unit of analysis, I resorted to different archival data to demonstrate in a first moment how, around the discipline of PM, there is a growing interest and then I drew a comparison between the two main existing professional strategies. The strategies focus, on the one hand, on the struggle to compete in the private and public sectors, and, on the other hand, between national and international level. Thus this thesis is the first detailed and comprehensive study in the field of PM within the Italian context. To analyze the development of the PM professional project, I looked mainly at the three main PM professional associations that are active in this field: PMI, IPMA, and ISIPM. The result shows that the development of PM in Italy is following a new pattern of professionalization with distinctive characteristics either respect to traditional professions that to the new ones.Modern economy, especially over the last 20 years, and the continuous development of new technologies brought to the modification of society and the way people work.

An assessment of the impact of possible CAP reform scenarios on Romanian agriculture
No full textUsing a simplified model, with key-variable the prices of two different possible scenarios of CAP reform after 2013 (moderate and radical), this paper present a comparison between the price effects of implementation of each reform scenario at 2015 horizon on Romanian agriculture. This short analysis shows that, under the presented hypotheses, the net welfare effect, due to the price changes, for the selected products, is positive in both reform scenarios, yet greater in the case of the radical reform. Integrated in the large context of Romanian development, it seems that the influence of CAP reform upon agriculture and rural areas will be most likely a gradual one: an interpenetration between the two scenarios is foreseeable, starting with the moderate reform that will dominate the period around 2013, the reform measures acquiring a more radical character afterwards.CAP reform, Romania, welfare effects, Agricultural and Food Policy,

Rich, Sturmian, and trapezoidal words
No full textIn this paper we explore various interconnections between rich words, Sturmian words, and trapezoidal words. Rich words, first introduced by the second and third authors together with J. Justin and S. Widmer, constitute a new class of finite and infinite words characterized by having the maximal number of palindromic factors. Every finite Sturmian word is rich, but not conversely. Trapezoidal words were first introduced by the first author in studying the behavior of the subword complexity of finite Sturmian words. Unfortunately this property does not characterize finite Sturmian words. In this note we show that the only trapezoidal palindromes are Sturmian. More generally we show that Sturmian palindromes can be characterized either in terms of their subword complexity (the trapezoidal property) or in terms of their palindromic complexity. We also obtain a similar characterization of rich palindromes in terms of a relation between palindromic complexity and subword complexity
Organizations are going to the Cloud: which competences for the IT Manager?
No full textCloud Computing (CC) is emerging as a new trend for managing IT resources within organizations. It also raises a broad range of issues from technically-oriented to organization-oriented related to cloud evolution and migration. It invites consideration of new models of governance for systems, service and organization. In order to take advantage from the opportunities offered by this technology, IT governance processes must be updated and aligned with the requirements emerging from CC adoption. As a consequence of this phenomenon, from the perspective of resources and organizational capabilities, CC requires a rethinking of the individual competences of IT managers to fill the gaps related to cloud adoption. In this paper we address the issue of identifying this gap by analyzing the impact of CC on both the activities of IT managers and the competence areas characterizing their professional profile. The results of this study provides guidelines for the development of training programs for IT managers. Furthermore the final discussion contribute to the debate on contingency relationships between CC configurations, individual competences, absorptive capacity and organizational capabilities.Cloud Computing (CC) is emerging as a new trend for managing IT resources within organizations.

System-on-chip Computing and Interconnection Architectures for Telecommunications and Signal Processing
No full textThis dissertation proposes novel architectures and design techniques targeting SoC building blocks for telecommunications and signal processing applications.
Hardware implementation of Low-Density Parity-Check decoders is approached at both the algorithmic and the architecture level. Low-Density Parity-Check codes are a promising coding scheme for future communication standards due to their outstanding error correction performance.
This work proposes a methodology for analyzing effects of finite precision arithmetic on error correction performance and hardware complexity. The methodology is throughout employed for co-designing the decoder. First, a low-complexity check node based on the P-output decoding principle is designed and characterized on a CMOS standard-cells library. Results demonstrate implementation loss below 0.2 dB down to BER of 10^{-8} and a saving in complexity up to 59% with respect to other works in recent literature. High-throughput and low-latency issues are addressed with modified single-phase decoding schedules. A new "memory-aware" schedule is proposed requiring down to 20% of memory with respect to the traditional two-phase flooding decoding. Additionally, throughput is doubled and logic complexity reduced of 12%. These advantages are traded-off with error correction performance, thus making the solution attractive only for long codes, as those adopted in the DVB-S2 standard. The "layered decoding" principle is extended to those codes not specifically conceived for this technique. Proposed architectures exhibit complexity savings in the order of 40% for both area and power consumption figures, while implementation loss is smaller than 0.05 dB.
Most modern communication standards employ Orthogonal Frequency Division Multiplexing as part of their physical layer. The core of OFDM is the Fast Fourier Transform and its inverse in charge of symbols (de)modulation. Requirements on throughput and energy efficiency call for FFT hardware implementation, while ubiquity of FFT suggests the design of parametric, re-configurable and re-usable IP hardware macrocells. In this context, this thesis describes an FFT/IFFT core compiler particularly suited for implementation of OFDM communication systems. The tool employs an accuracy-driven configuration engine which automatically profiles the internal arithmetic and generates a core with minimum operands bit-width and thus minimum circuit complexity. The engine performs a closed-loop optimization over three different internal arithmetic models (fixed-point, block floating-point and convergent block floating-point) using the numerical accuracy budget given by the user as a reference point. The flexibility and re-usability of the proposed macrocell are illustrated through several case studies which encompass all current state-of-the-art OFDM communications standards (WLAN, WMAN, xDSL, DVB-T/H, DAB and UWB). Implementations results are presented for two deep sub-micron standard-cells libraries (65 and 90 nm) and commercially available FPGA devices. Compared with other FFT core compilers, the proposed environment produces macrocells with lower circuit complexity and same system level performance (throughput, transform size and numerical accuracy).
The final part of this dissertation focuses on the Network-on-Chip design paradigm whose goal is building scalable communication infrastructures connecting hundreds of core. A low-complexity link architecture for mesochronous on-chip communication is discussed. The link enables skew constraint looseness in the clock tree synthesis, frequency speed-up, power consumption reduction and faster back-end turnarounds. The proposed architecture reaches a maximum clock frequency of 1 GHz on 65 nm low-leakage CMOS standard-cells library. In a complex test case with a full-blown NoC infrastructure, the link overhead is only 3% of chip area and 0.5% of leakage power consumption.
Finally, a new methodology, named metacoding, is proposed. Metacoding generates correct-by-construction technology independent RTL codebases for NoC building blocks. The RTL coding phase is abstracted and modeled with an Object Oriented framework, integrated within a commercial tool for IP packaging (Synopsys CoreTools suite). Compared with traditional coding styles based on pre-processor directives, metacoding produces 65% smaller codebases and reduces the configurations to verify up to three orders of magnitude
