Italy's got talent. How Italian leading companies in confectionery industry overcame the crisis

The crisis that spread worldwide since 2007 started from the financial sector and ended to affect also real economy. This process has attracted the attention of many scholars seeking to study its causes and impacts. Notwithstanding many works on this topic, the impact of the crisis on specific industries is still rather unexplored. The present work seeks to address this issue by analyzing the confectionery industry, with particular emphasis for Italian market leaders, Ferrero S.p.A. and Perfetti Van Melle S.r.l.. The aim of the study is to assess if they have been successful in tackling the crisis, keeping a satisfactory level of profitability associated to a good financial health notwithstanding ongoing difficulties. Moreover, we seek to analyze the strategies the companies employed to survive the crisis. The concern of the paper is both quantitative and qualitative. Thus, we calculated a complete set of indicators using a specific methodology for financial statement analysis which has been conceived especially for studying Italian firms; these data have been integrated with other information retrieved from the annual reports of the companies (especially the notes to the accounts and the directors’ report). The analysis highlights that both the firms benefit from a good financial health, with Perfetti Van Melle presenting a large amount of liquidity. On the contrary, liquidity should be the main concern of Ferrero because of an excessive reliance on current liabilities. Both the firms have a good level of profitability, even if Perfetti Van Melle’s one is decreasing. The key-strategies for the success of these firms are ongoing investments in state-of-the-art plant and machinery, an increasing use of equity as the main source of funding, along with huge investments in research and advertising.

An Analysis of Soft Law Applicable to Humanitarian Assistance: Relative Normativity in Action?

There is limited binding international law specifically covering the provision of humanitarian assistance in response to natural and human-made disasters. Yet a variety of authoritative soft law texts have been developed in the past 20 years, including the UN Guiding Principles on Internal Displacement, the Red Cross Red Crescent Code of Conduct and the Sphere Project’s Humanitarian Charter and Minimum Standards in Disaster Response. While such ‘non-binding normative standards’ do not carry the weight of international law, they play an essential role in the provision of humanitarian assistance albeit subject to their limited enforceability vis-à-vis intended beneficiaries and to their voluntary application by humanitarian actors. Notwithstanding a lack of legal compulsion, certain non-binding normative standards may directly influence the actions of States and non-State actors, and so obtain a strongly persuasive character. Analysis of texts that influence the practice of humanitarian assistance advances our understanding of humanitarian principles and performance standards for disaster response. As the International Law Commission debates draft articles on the Protection of Persons in the Event of Disasters, such non-binding normative standards are crucial to the development of an internationally accepted legal framework to protect victims of disasters.

Electron impact excitation of Mg VIII: Collision strengths, transition probabilities and theoretical EUV and soft X-ray line intensities for Mg VIII

Context: Mg VIII emission lines are observed in a range of astronomical objects such as the Sun, other cool stars and in the coronal line region of Seyfert galaxies. Under coronal conditions Mg VIII emits strongly in the extreme ultraviolet (EUV) and soft X-ray spectral regions which makes it an ideal ion for plasma diagnostics.

Aims. Two theoretical atomic models, consisting of 125 fine structure levels, are developed for the Mg VIII ion. The 125 levels arise from the 2s(2)2p, 2s(2)p2, 2p(3), 2s(2)3s, 2s(2)3p, 2s(2)3d, 2s2p3s, 2s2p3p, 2s2p3d, 2p(2)3s, 2p(2)3p and 2p(2)3d configurations. Electron impact excitation collision strengths and radiative transition probabilities are calculated for both Mg VIII models, compared with existing data, and the best model selected to generate a set of theoretical emission line intensities. The EUV lines, covering 312-790 angstrom, are compared with existing solar spectra (SERTS-89 and SUMER), while the soft X-ray transitions (69-97 angstrom) are examined for potential density diagnostic line ratios and also compared with the limited available solar and stellar observational data.

Methods. The R-matrix codes Breit-Pauli RMATRXI and RMATRXII are utilised, along with the PSTGF code, to calculate the collision strengths for two Mg VIII models. Collision strengths are averaged over a Maxwellian distribution to produce the corresponding effective collision strengths for use in astrophysical applications. Transition probabilities are also calculated using the CIV3 atomic structure code. The best data are then incorporated into the modelling code CLOUDY and line intensities generated for a range of electron temperatures and densities appropriate to solar and stellar coronal plasmas.

Results. The present effective collision strengths are compared with two previous calculations. Good levels of agreement are found with the most recent, but there are large differences with the other for forbidden transitions. The resulting line intensities compare favourably with the observed values from the SERTS-89 and SUMER spectra. Theoretical soft X-ray emission lines are presented and several density diagnostic line ratios examined, which are in reasonable agreement with the limited observational data available.

Dataflow toolset for soft-core processors on FPGA for image processing applications

With security and surveillance, there is an increasing need to be able to process image data efficiently and effectively either at source or in a large data networks. Whilst Field Programmable Gate Arrays have been seen as a key technology for enabling this, they typically use high level and/or hardware description language synthesis approaches; this provides a major disadvantage in terms of the time needed to design or program them and to verify correct operation; it considerably reduces the programmability capability of any technique based on this technology. The work here proposes a different approach of using optimised soft-core processors which can be programmed in software. In particular, the paper proposes a design tool chain for programming such processors that uses the CAL Actor Language as a starting point for describing an image processing algorithm and targets its implementation to these custom designed, soft-core processors on FPGA. The main purpose is to exploit the task and data parallelism in order to achieve the same parallelism as a previous HDL implementation but avoiding the design time, verification and debugging steps associated with such approaches.

Active Controllers or Wealthy Rentiers?: Large Shareholders in Victorian Public Companies

This article addresses the issue of whether large shareholders in Victorian public companies were active in the control of companies or were simply wealthy rentiers. Using ownership records for 890 firm-years, we examine the control rights, socio-occupational background, and wealth of large shareholders. We find that many large shareholders had limited voting rights and neither they nor family members were directors. This implies that the majority of public companies in the second half of the nineteenth century cannot be characterized as family companies and that large shareholders are better viewed as wealthy gentlemen capitalists rather than entrepreneurs.

A Soft Sensor for Viscosity Control of Polymer Extrusion

Viscosity represents a key indicator of product quality in polymer extrusion but has traditionally been difficult to measure in-process in real-time. An innovative, yet simple, solution to this problem is proposed by a Prediction-Feedback observer mechanism. A `Prediction' model based on the operating conditions generates an open-loop estimate of the melt viscosity; this estimate is used as an input to a second, `Feedback' model to predict the pressure of the system. The pressure value is compared to the actual measured melt pressure and the error used to correct the viscosity estimate. The Prediction model captures the relationship between the operating conditions and the resulting melt viscosity and as such describes the specific material behavior. The Feedback model on the other hand describes the fundamental physical relationship between viscosity and extruder pressure and is a function of the machine geometry. The resulting system yields viscosity estimates within 1% error, shows excellent disturbance rejection properties and can be directly applied to model-based control. This is of major significance to achieving higher quality and reducing waste and set-up times in the polymer extrusion industry.

Lanthanide luminescent logic gate mimics in soft matter: [H(+)] and [F(-)] dual-input device in a polymer gel with potential for selective component release

The non-covalent incorporation of responsive luminescent lanthanide, Ln(iii), complexes with orthogonal outputs from Eu(iii) and Tb(iii) in a gel matrix allows for in situ logic operation with colorimetric outputs. Herein, we report an exemplar system with two inputs ([H(+)] and [F(-)]) within a p(HEMA-co-MMA) polymer organogel acting as a dual-responsive device and identify future potential for such systems.

FPGA Soft-core Processors, Compiler and Hardware Optimizations validated using HOG

There is demand for an easily programmable, high performance image processing platform based on FPGAs. In previous work, a novel, high performance processor - IPPro was developed and a Histogram of Orientated Gradients (HOG) algorithm study undertaken on a Xilinx Zynq platform. Here, we identify and explore a number of mapping strategies to improve processing efficiency for soft-cores and a number of options for creation of a division coprocessor. This is demonstrated for the revised high definition HOG implementation on a Zynq platform, resulting in a performance of 328 fps which represents a 146% speed improvement over the original realization and a tenfold reduction in energy.

Soft-core Stream Processor for Sliding Window Applications

Software-programmable `soft' processors have shown tremendous potential for efficient realisation of high performance signal processing operations on Field Programmable Gate Array (FPGA), whilst lowering the design burden by avoiding the need to design fine-grained custom circuit archi-tectures. However, the complex data access patterns, high memory bandwidth and computational requirements of sliding window applications, such as Motion Estimation (ME) and Matrix Multiplication (MM), lead to low performance, inefficient soft processor realisations. This paper resolves this issue, showing how by adding support for block data addressing and accelerators for high performance loop execution, performance and resource efficiency over four times better than current best-in-class metrics can be achieved. In addition, it demonstrates the first recorded real-time soft ME estimation realisation for H.263 systems.

Soft-core Stream Processing on FPGA: An FFT Case Study

The increasing design complexity associated with modern Field Programmable Gate Array (FPGA) has prompted the emergence of 'soft'-programmable processors which attempt to replace at least part of the custom circuit design problem with a problem of programming parallel processors. Despite substantial advances in this technology, its performance and resource efficiency for computationally complex operations remains in doubt. In this paper we present the first recorded implementation of a softcore Fast-Fourier Transform (FFT) on Xilinx Virtex FPGA technology. By employing a streaming processing architecture, we show how it is possible to achieve architectures which offer 1.1 GSamples/s throughput and up to 19 times speed-up against the Xilinx Radix-2 FFT dedicated circuit with comparable cost.
