Energy Management Module for Mobile Robots in Hostile Environments

In hostile environments at CERN and other similar scientific facilities, having a reliable mobile robot system is essential for successful execution of robotic missions and to avoid situations of manual recovery of the robots in the event that the robot runs out of energy. Because of environmental constraints, such mobile robots are usually battery-powered and hence energy management and optimization is one of the key challenges in this field. The ability to know beforehand the energy consumed by various elements of the robot (such as locomotion, sensors, controllers, computers and communication) will allow flexibility in planning or managing the tasks to be performed by the robot.

Housing plans and urban rehabilitation in Spain, 1992-2012

This paper explores the urban rehabilitation projects promoted by the Spanish Government between 1992 and 2012 through housing plans. The analysis is based on the comparison of programmes and estimations gathered in these plans with actual housing production within this period in order to find the connection between sectoral housing planning and real estate cycles in these last twenty years. During the period under review, six state housing plans, that were mainly focused on the promotion of newly-constructed state-subsidised housing, were developed, including the Areas of Integrated Rehabilitation programmes (ARI programmes). In spite of the relevance and growing complexity of these programmes, these played a subsidiary role in the government housing policy and were insignificant regarding the whole real estate production in this period.

Loss of p21 increases sensitivity to ionizing radiation and delays the onset of lymphoma in atm-deficient mice

Ataxia telangiectasia (AT) is an autosomal recessive disorder characterized by growth retardation, cerebellar ataxia, oculocutaneous telangiectasias, and a high incidence of lymphomas and leukemias. In addition, AT patients are sensitive to ionizing radiation. Atm-deficient mice recapitulate most of the AT phenotype. p21cip1/waf1 (p21 hereafter), an inhibitor of cyclin-dependent kinases, has been implicated in cellular senescence and response to γ-radiation-induced DNA damage. To study the role of p21 in ATM-mediated signal transduction pathways, we examined the combined effect of the genetic loss of atm and p21 on growth control, radiation sensitivity, and tumorigenesis. As might have been expected, our data provide evidence that p21 modifies the in vitro senescent response seen in AT fibroblasts. Further, it is a downstream effector of ATM-mediated growth control. In addition, however, we find that loss of p21 in the context of an atm-deficient mouse leads to a delay in thymic lymphomagenesis and an increase in acute radiation sensitivity in vivo (the latter principally because of effects on the gut epithelium). Modification of these two crucial aspects of the ATM phenotype can be related to an apparent increase in spontaneous apoptosis seen in tumor cells and in the irradiated intestinal epithelium of mice doubly null for atm and p21. Thus, loss of p21 seems to contribute to tumor suppression by a mechanism that operates via a sensitized apoptotic response. These results have implications for cancer therapy in general and AT patients in particular.

Quality Control in the Secretory Pathway: The Role of Calreticulin, Calnexin and BiP in the Retention of Glycoproteins with C-Terminal Truncations

Unlike properly folded and assembled proteins, most misfolded and incompletely assembled proteins are retained in the endoplasmic reticulum of mammalian cells and degraded without transport to the Golgi complex. To analyze the mechanisms underlying this unique sorting process and its fidelity, the fate of C-terminally truncated fragments of influenza hemagglutinin was determined. An assortment of different fragments was generated by adding puromycin at low concentrations to influenza virus-infected tissue culture cells. Of the fragments generated, <2% was secreted, indicating that the system for detecting defects in newly synthesized proteins is quite stringent. The majority of secreted species corresponded to folding domains within the viral spike glycoprotein. The retained fragments acquired a partially folded structure with intrachain disulfide bonds and conformation-dependent antigenic epitopes. They associated with two lectin-like endoplasmic reticulum chaperones (calnexin and calreticulin) but not BiP/GRP78. Inhibition of the association with calnexin and calreticulin by the addition of castanospermine significantly increased fragment secretion. However, it also caused association with BiP/GRP78. These results indicated that the association with calnexin and calreticulin was involved in retaining the fragments. They also suggested that BiP/GRP78 could serve as a backup for calnexin and calreticulin in retaining the fragments. In summary, the results showed that the quality control system in the secretory pathway was efficient and sensitive to folding defects, and that it involved multiple interactions with endoplasmic reticulum chaperones.

La memoria della pubblicità. Il ruolo dell'archivio. Il fondo Art Directors Club Italiano conservato al Centro Studi e Archivio della Comunicazione dell'Università di Parma.

La ricerca ha scelto di affrontare una serie di problemi connessi alla valorizzazione e alla conservazione del materiale pubblicitario rispetto a un caso studio selezionato, l’archivio dell’Art Directors Club Italiano conservato presso il Centro Studi e Archivio della Comunicazione dell’Università di Parma. Questo archivio è costituito principalmente da materiali della comunicazione pubblicitaria - suddivisi in categorie corrispondenti a media e tecniche - iscritti dal 1998 al 2003 agli ADCI Awards, il premio italiano di riferimento dedicato alla pubblicità e organizzato dall’Art Directors Club Italiano - ADCI a partire dall’anno della sua fondazione, il 1985. La sua storia è quindi connessa strettamente con quella dell’associazione, che rappresenta e riunisce professionisti della pubblicità che condividono obiettivi comuni, e in particolare il riconoscimento e la valorizzazione della creatività come elemento fondante della comunicazione d’impresa e istituzionale. Lo CSAC in parallelo, il contesto archivistico all’interno del quale questi fondi sono venuti a trovarsi in seguito alla donazione da parte dell’ADCI nel 2002-2003, è un centro di ricerca dell’Università di Parma dedicato alla conservazione e allo studio di archivi provenienti da diversi ambiti culturali. A partire da una mappatura dell’archivio e dalla ricostruzione di contesti e dibattiti fondamentali per studiare e organizzare i fondi, questa tesi si propone di individuare, in particolare attraverso gli strumenti digitali, possibili modalità di analisi, esposizione e accesso ai materiali, che possano aprire una rete di connessioni verso altri ambiti di ricerca e nuove prospettive in funzione delle storie della pubblicità.

Family firms and the great crisis: evidence from the italian case

Few studies have analyzed how family firms have acted during the global great crisis in comparison to their nonfamily counterparts. This paper tries to fill this gap on the basis of the Italian experience using a sample of almost 4,500 for 2007 and 2010. We study whether family control affects labour productivity, labour costs and competitiveness and if the adoption of performance related pay (PRP) reveals an efficacious strategy to mitigate the effects of the crisis and reduce the gap in competitiveness with respect to nonfamily firms. We use quantile regression techniques to test the heterogeneous role of PRP and pay attention for its possible endogeneity. We have observed that after the outburst of the crisis, the distance in terms of competitiveness of family firms with respect to their nonfamily counterparts has been amplified. We also find that family firms may take advantage from the adoption of incentive schemes, such as PRP, to encourage commitment and motivation from their employees more than nonfamily firms. The positive role of PRP on labour productivity, coupled with a moderate influence of these schemes on wage premiums, enable them to regain competitiveness also under hostile pressures, as those featuring the strong global crisis.

Private (Brown) Eyes: Ethnicity, Genre and Gender in Crime Fiction in the Gloria Damasco novels and the Chicanos Comic Series

The representation of women in crime fiction has traditionally been a complicated one. Consistently forced into secondary characters (assistants, girlfriends, or damsels in distress) the most active role a female character could aspire to was that of the femme fatale, a pit of perdition, an unwelcome distraction for a man looking for truth and justice. This traditional approach to the genre has been challenged in the last decades by women acting as detectives, trusted with solving their cases in a hostile male world. Similarly, the traditional white male protagonist has been contested by fictions where ethnic minorities are not just consigned to the criminal world, but where detectives are members of ethnic groups, and can use their knowledge of the community to solve the case. This essay focuses on the crossroads of ethnic and women’s detective fiction, specifically the Gloria Damasco series by Chicana writer Lucha Corpi and the graphic novel Chicanos (Trillo and Risso, 1996). Both protagonists (Gloria Damasco, a Chicana clairvoyant detective, and “poor, ugly, and a detective” Alejandrina Yolanda Jalisco) must face both the dangers of investigating criminal cases and discrimination in their professional surroundings due to their gender and ethnicity. By contrasting these texts, the essay elucidates the importance of specific cultural products, their connection to (and defiance of) canonical forms of the genre, and their rejection of generic and gender expectations.

An un-mounted horse care group for children and youth with an Autism Spectrum Disorder: Recommendations for program development and treatment intervention

Equine Assisted Activities and Therapies (EAAT) including Therapeutic Horseback Riding (THR) and un-mounted equine assisted activities are interventions aimed at improving the daily functioning and success of individuals with disabilities, including those with an autism spectrum disorder (ASD). While THR is frequently utilized as a treatment intervention for children with ASD, there are many limitations (individual's weight, horse health, weather, physical limitations, health conditions, etc.) that prevent this population from participating in mounted programs. Un-mounted equine assisted activities are often utilized as an alternative, but they are not informed by empirical research or a standardized treatment model. This paper provides a comprehensive review of the literature for EAAT including un-mounted programs, examination of organizational guidelines as they apply to un-mounted programs, and consultation with program directors regarding current practices in the field, and finally it establishes recommendations for the development of a standard curriculum that would strengthen un-mounted horse care group programs serving children with ASD.

Comment Letter: The NYSE and the End of the Structural Separation between Regulatory and Commercial Interests of the Exchange

The NYSE transformed into a for profit entity in 2006. As part of the approval process, the NYSE agreed to structurally separate the regulatory function from the business function. In doing so, the NYSE created NYSE Regulation, a non-profit with an independent board, to handle most regulatory matters. During the comment period, a spirited debate arose over the ability of a for profit company to carry out a regulatory mission. Some suggested that the regulatory function was incompatible with a "for profit" motive and that NYSE Regulation should be spun off. Others accepted the proposed structure but called for additional changes designed to reduce the possible influence of the public holding company over the regulatory function. In the end, the SEC approved the structure but with a number of prophylactic safeguards including the requirement that NYSE Regulation have a board consisting of all independent directors (save the CEO) and that directors from the for profit holding company could not make up a majority of the board. More recently, however, the NYSE has proposed to end the structural separation of the two functions and instead put in place a functional separation. The proposal would result in the termination of the delegation agreement between the Exchange and NYSE Regulation and the creation of both a Regulatory Oversight Committee of the Board of Directors of the Exchange and the creation of a Chief Regulatory Officer. This letter examines the history of the separation of the two functions and critiques the NYSE's proposal.

Abandoned and forgotten: the sad story of Kenya's internally displaced persons

This documentary is about the internal displacement of ethnic minorities brought about by politically instigated post-election violence towards ethnic minorities in all eight provinces, namely, Coast, Rift Valley, Western, Eastern, North Eastern, Central Kenya, Nairobi, and Nyanza. During the years of 1991 to 1996, over 15,000 people died and almost 300,000 were displaced in the Rift Valley, Central, Nyanza and Western provinces. Before the 1997 elections, violence erupted. Again, following the disputed presidential elections in December 2007 politically and ethnically instigated displacements resulted in human rights violations against 600,000 people in 8 provinces of Kenya.

A Legal and Economic Assessment of European Takeover Regulation. CEPS Paperbacks. December 2012

Takeovers are one-off events, altering control and strategy within an organisation. But the chances of becoming the target of a bid, even where remote, daily influence corporate decision-making. Takeover rules are therefore central to company law and the balance of power among managers, shareholders and stakeholders alike. This study analyses the corporate governance drivers underpinning takeover bid regulations and assesses the implementation of the EU Directive on takeover bids and compares it with the legal framework of nine other major jurisdictions, including the US. It finds that similar rules have different effects depending on company-level and country-level characteristics and considers the use of modular legislation and optional provisions to cater for them.

Helpless and lonely: Turkey's attitude towards the war in Syria. OSW Commentary No. 136, 09.05.2014

The conflict in Syria, which has lasted since 2011, has become the most significant test of the efficiency of Turkey’s foreign policy and the biggest challenge to Turkey’s security in recent decades. The lack of a clear prospect of an end to the war does not allow us to come to a final conclusion regarding the Syrian civil war’s importance for Turkey. However, it can be said today that with the exception of the initial phase of the conflict, Ankara’s influence over the course of events in Syria has been limited, and the war itself is evolving in a direction that is unfavourable for Turkey: the hostile regime of Bashar al-Assad is still in power, the opposition has proved to be an unreliable or even a dangerous ally, and in northern Syria militant jihadist groups and Kurds are gaining importance. It is also quite unlikely that the West will take any greater responsibility for stabilising the situation in the region. In response to such an unfortunate situation, and out of fear of risking deeper involvement in the conflict, during the past year Turkey’s policy towards Syria has been restrained, reactive and focused mainly on defending Turkey’s territory. However, this policy offers no security guarantees and does not prevent the country’s regional position from weakening, especially in the context of the reinforcement of the jihadist militants and the Kurdish autonomy in northern Syria. The arguments for Turkey continuing its defensive policy are strong: the country fears the possible results of an open confrontation with Assad’s forces; most probably it could not count on support for such actions from within its own society or its Western allies. It also does not have enough acceptance within the anti-Assad opposition circles. On the other hand, though, the risk of uncontrolled development of events is still present; the risk of confrontations with armed jihadist militants is growing; and the potential operation of Turkish forces, either against the jihadists or against Assad’s army, could be considered as a method of diverting attention from the political problems with which the AKP government has been struggling at home.

Mixed Public-Private Enterprises in Europe: Economic Theory and an Empirical Analysis of Italian Water Utilities. Bruges European Economic Research (BEER) Papers 4/July 2006

Mixed enterprises, which are entities jointly owned by the public and private sector, are spreading all over Europe in local utilities. Well aware that in the vast majority of cases the preference of local authorities towards such governance structure is determined by practical reasons rather than by the ambition to implement new regulatory designs (an alternative to the typical “external” regulation), our purpose is to confer some scientific value to this phenomenon which has not been sufficiently investigated in the economic literature. This paper aims at proposing an economic analysis of mixed enterprises, especially of the specific configuration in which the public partner acts as controller and the private one (or “industrial” partner) as service provider. We suggest that the public service concession to mixed enterprises could embody, under certain conditions, a noteworthy substitute to the traditional public provision and the concession to totally private enterprises, as it can push regulated operators to outperform and limit the risk of private opportunism. The starting point of the entire analysis is that ownership allows the (public) owner to gather more information about the actual management of the firm, according to property rights theory. Following this stream of research, we conclude that under certain conditions mixed enterprises could significantly reduce asymmetric information between regulators and regulated firms by implementing a sort of “internal” regulation. With more information, in effect, the public authority (as owner/controller of the regulated firm, but also as member of the regulatory agency) can stimulate the private operator to be more efficient and can monitor it more effectively with respect to the fulfilment of contractual obligations (i.e., public service obligations, quality standards, etc.). Moreover, concerning the latter function, the board of directors of the mixed enterprise can be the suitable place where public and private representatives (respectively, welfare and profit maximisers) can meet to solve all disputes arising from incomplete contracts, without recourse to third parties. Finally, taking into account that a disproportionate public intervention in the “private” administration (or an ineffective protection of the general interest) would imply too many drawbacks, we draw some policy implications that make an equitable debate on the board of the firm feasible. Some empirical evidence is taken from the Italian water sector.

Supporting the Revolution: America, Democracy, and the End of the Cold War in Poland, 1981-1989. ACES Working Paper (Report) No. 8, 2007

Early on the morning of December 13, 1981, General Wojciech Jaruzelski, the leader of the communist Polish United Workers' Party (PZPR), declared martial law, ending the so-called "Polish Crisis," which began with the creation of the Independent Free Trade Union "Solidamosc" in August 1980. Over the next eight years, the Communist government and the opposition struggled over power, culminating in 1989 with the creation of a Solidamosc-led government which ended fifty years of Communist rule in Poland and led the way to further democratic revolutions throughout Eastern Europe. The purpose of this dissertation is to utilize newly available and underutilized archival sources as well as oral history interviews, from both international and American perspectives, to fully chronicle American policy toward Poland from the declaration of martial law until the creation of the Solidarnosc government. Rather than explaining Polish-American relations in bilateral terms, the dissertation illuminates the complex web of influences that determined American policy in Washington and affected its implementation within Poland. This includes descriptions of internal tensions within the Reagan administration, differences between American decisions in Washington and implementation in Warsaw, lobbying from Polish-American groups, clashes between Capitol Hill and the White House, coordination with American labor organizations to support Solidarnosc, disagreements with West European allies in NATO and international financial organizations, cooperation with the Vatican and the Polish Catholic Church, synchronization with American humanitarian organizations working in Poland, limitations caused by the realities of Soviet power in Eastern Europe, and complications caused by domestic Polish concerns. By taking a broad view of American policy and highlighting internal Polish decisions, with both the Communist government and the democratic opposition, the dissertation provides concrete examples of America's role in Poland's transformation, arguing, however, that this role was very limited. These conclusions are relevant to arguments about the end of the Cold War, the nature of American power, as well as current discussions about possibilities to promote democracy within hostile regimes.

EU-Turkey Summit on the refugee crisis Law and (dis)order? EPC Commentary, 21 March 2016

After many meetings and long hours of negotiations, the overwhelming feeling when a deal between the EU and Turkey was struck, was one of “mission accomplished”! Faced with an unprecedented crisis and forced to appease increasingly hostile public opinions back home, EU leaders had only one objective in mind: reducing the number of migrants arriving in the EU so that order can return in the framework of EU rules. However, a closer look at the Summit Conclusions and the EU-Turkey statement leaves a bitter taste, according to Yves Pascouau. In this Commentary, he questions the feasibility of the final EU-Turkey deal, saying that it creates more problems than it solves: besides the obvious legal and practical issues, it is far from certain which member states will be willing to do their part, or whether or not the EU can come up with a strategic vision on human mobility for the future.
