Embodiment of intersubjective time: relational dynamics as attractors in the temporal coordination of interpersonal behaviors and experiences
Julien Laroche,Anna Maria Berardi,Eric Brangier
Frontiers in Psychology , 2014, DOI: 10.3389/fpsyg.2014.01180
Abstract: This paper addresses the issue of “being together,” and more specifically the issue of “being together in time.” We provide with an integrative framework that is inspired by phenomenology, the enactive approach and dynamical systems theories. To do so, we first define embodiment as a living and lived phenomenon that emerges from agent-world coupling. We then show that embodiment is essentially dynamical and therefore we describe experiential, behavioral and brain dynamics. Both lived temporality and the temporality of the living appear to be complex, multiscale phenomena. Next we discuss embodied dynamics in the context of interpersonal interactions, and briefly review the empirical literature on between-persons temporal coordination. Overall, we propose that being together in time emerges from the relational dynamics of embodied interactions and their flexible co-regulation.

Abstract: This paper will reflect on the evolution of the functionality of ABC model, focusing attention on the variables that determine success or failure in its implementation. To this end the paper, through the empirical and theoretical literature review, will: trace the evolution of the ABC model, while highlighting the implications of the implementation process, analyze the concept of success in its implementation and discuss the determinants that influence the outcome, focusing on the organizational variables that firm have to control in order to succeed with ABC.
Evaluation of the Effectiveness of a 4-Months Continuous Injection of a Gas Mixture (CO2 and Inert Gases) on Legionella Contamination of a Hot Water Distribution System  [PDF]
Maria Anna Coniglio
Health (Health) , 2015, DOI: 10.4236/health.2015.77096
Abstract: Within the biofilm and scales Legionella is less far susceptible to the effects of the most frequently used biocides. The objective of this study was to evaluate the effect of a 4-months continuous injection of a gas mixture (CO2 and inert gas) in the hot water distribution system of a large hotel colonized by L. pneumophila sg3 on limiting biofilm formation and scales and in turn Legionella growth. Before the continuous injection of the gas mixture, out of the 15 sampling points examined every month 60% were colonized by Legionella (mean concentrations of 102 cfu/L in the boilers and the return loop, and 104 cfu/L in taps and showers). One week after the injection of the gas mixture and daily fluxing of the distal outlets, the level of colonization decreased (<103 cfu/L). When it was decided to flux all the distal outlets only 1 day per week the mean concentration of Legionella increased again (>104 cfu/L) in all the sampling points. Thus, cleaning of the boilers was performed and distal outlets were again fluxed daily. One week after the level of contamination decreased again (<102 cfu/L). Nonetheless, the colonization was not eliminated and when fluxing of the distal outlets was not performed every day the mean concentrations of Legionella raised up to >104 cfu/L. Results indicate that the gas mixture was able to reduce the level of colonization by Legionella only because associated to the fluxing of the distal outlets.
Sustainability of the Greek Government Net Borrowing: An Analytical and Comprehensive Exposition  [PDF]
Anna Maria Mouza
Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.64081
Abstract: This paper aims to investigate the sustainability of the general Greek government net borrowing, applying novel techniques for both to determine the order of integration of a difference stationary series and to specify the final form of the co-integration equation. Co-integration analysis was applied, and robust rules of thumb are suggested taking into account the individuality of the case under consideration. The empirical application revealed that the Greek debt is not sustainable. Further, we introduce consistent planning methods to obtain optimal time paths for both government revenue and spending, so as sustainability of the debt to become a feasible task under certain assumptions. Finally, we suggest a policy making approach on macrolevel combining co-integration with optimal control.

Nicola Silvestris, Francesco Pantano, Toni Ibrahim, Teresa Gamucci, Fernando De Vita, Teresa Di Palma, Paolo Pedrazzoli, Sandro Barni, Antonio Bernardo, Antonio Febbraro, Maria Antonietta Satolli, Paola Bertocchi, Vincenzo Catalano, Elisa Giommoni, Alessandro Comandone, Evaristo Maiello, Ferdinando Riccardi, Raimondo Ferrara, Antonio Trogu, Rossana Berardi, Silvana Leo, Alessandro Bertolini, Francesco Angelini, Saverio Cinieri, Antonio Russo, Salvatore Pisconti, Anna Elisabetta Brunetti, Amalia Azzariti, Daniele Santini
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0074402
Abstract: Background Bone metastasis represents an increasing clinical problem in advanced gastric cancer (GC) as disease-related survival improves. In literature, few data on the natural history of bone disease in GC are available. Patients and Methods Data on clinicopathology, skeletal outcomes, skeletal-related events (SREs), and bone-directed therapies for 208 deceased GC patients with evidence of bone metastasis were statistically analyzed. Results Median time to bone metastasis was 8 months (CI 95%, 6.125–9.875 months) considering all included patients. Median number of SREs/patient was one. Less than half of the patients (31%) experienced at least one and only 4 and 2% experienced at least two and three events, respectively. Median times to first and second SRE were 2 and 4 months, respectively. Median survival was 6 months after bone metastasis diagnosis and 3 months after first SRE. Median survival in patients who did not experience SREs was 5 months. Among patients who received zoledronic acid before the first SRE, the median time to appearance of first SRE was significantly prolonged compared to control (7 months vs 4 months for control; P: 0.0005). Conclusions To our knowledge, this retrospective analysis is the largest multicenter study to demonstrate that bone metastases from GC are not so rare, are commonly aggressive and result in relatively early onset of SREs in the majority of patients. Indeed, our large study, which included 90 patients treated with ZOL, showed, for the first time in literature, a significant extension of time to first SRE and increase in the median survival time after diagnosis of bone metastasis. Taken together, these data may support the beneficial effects of ZOL in GC patients.
Environmental Enrichment Effects on Development of Retinal Ganglion Cell Dendritic Stratification Require Retinal BDNF
Silvia Landi, Maria Cristina Cenni, Lamberto Maffei, Nicoletta Berardi
PLOS ONE , 2007, DOI: 10.1371/journal.pone.0000346
Abstract: A well-known developmental event of retinal maturation is the progressive segregation of retinal ganglion cell (RGC) dendrites into a and b sublaminae of the inner plexiform layer (IPL), a morphological rearrangement crucial for the emergence of the ON and OFF pathways. The factors regulating this process are not known, although electrical activity has been demonstrated to play a role. Here we report that Environmental Enrichment (EE) accelerates the developmental segregation of RGC dendrites and prevents the effects exerted on it by dark rearing (DR). Development of RGC stratification was analyzed in a line of transgenic mice expressing plasma-membrane marker green fluorescent protein (GFP) under the control of Thy-1 promoter; we visualized the a and b sublaminae of the IPL by using an antibody selectively directed against a specific marker of cholinergic neurons. EE precociously increases Brain Derived Neurotrophic Factor (BDNF) in the retina, in parallel with the precocious segregation of RGC dendrites; in addition, EE counteracts retinal BDNF reduction in DR retinas and promotes a normal segregation of RGC dendrites. Blocking retinal BDNF by means of antisense oligos blocks EE effects on the maturation of RGC dendritic stratification. Thus, EE affects the development of RGC dendritic segregation and retinal BDNF is required for this effect to take place, suggesting that BDNF could play an important role in the emergence of the ON and OFF pathways.

Receptor-Drug Interaction: Europium Employment for Studying the Biochemical Pathway of G-Protein-Coupled Receptor Activation
Colabufo Nicola Antonio,Perrone Maria Grazia,Contino Marialessandra,Berardi Francesco
Metal-Based Drugs , 2008, DOI: 10.1155/2007/12635
Abstract: In medicinal chemistry field, the biochemical pathways, involved in 7-transmembrane domains G-protein coupled receptors (GPCRs) activation, are commonly studied to establish the activity of ligands towards GPCRs. The most studied steps are the measurement of activated GTP- ± subunit and stimulated intracellular cAMP. At the present, many researchers defined agonist or antagonist activity of potential GPCRs drugs employing [35S]GTP 3S or [3H]cAMP as probes. Recently, the corresponding lanthanide labels Eu-GTP and Eu-cAMP as alternative to radiochemicals have been developed because they are highly sensitive, easy to automate, easily synthesized, they display a much longer shelf-life and they can be used in multilabel experiments. In the present review, the receptor-drug interaction by europium employment for studying the biochemical pathway of GPCR activation has been focused. Moreover, comparative studies between lanthanide label probes and the corresponding radiolabeled compounds have been carried out.
The Fragmentation of Entrepreneurial Functionand the Role of External Control on Management Behavior  [PDF]
Pietro Gottardo, Anna Maria Moisello
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.34045
Abstract: Starting from the interpretation of corporate governance as the outcome of the fragmentation of entrepreneurial power and the related agency problem, the paper stresses the strict relationship between management control and risk management. This issue implies the need of effective internal and external controls, i.e. board implementation and supervision of a consistent control function and auditing, but the market and public regulatory authorities give the most important external control system. The paper focuses next on the role of the Codes of Conduct, the critical aspects of their effectiveness and other key issues in the governance of corporations highlighted by the last financial and economic crisis.
