Imprenditorialitŕ e nascita di nuove imprese innovative in Europa: un'analisi delle determinanti in alcuni settori ad alta tecnologia
Authors: Lenzi Camilla , Mancusi Maria Luisa 
Published: July 2021

- This paper evaluates the importance of some key elements in the process leading to the birth and start-up of a new firm. We focus on a sample of recently founded and innovative European firms in technological fields characterised by strong innovative and competitive dynamics in the last 15 years. Emphasis is placed both on the role of the founder and on the assets exploited and developed in the new ventures early stages. The analysis of the questionnaire confirms the importance of the intellectual capital of the founder and of the scientific and technological knowledge acquired during advanced studies or previous work experiences. It further confirms the importance of the human and financial capital (particularly, access to external funds) necessary to the start of entrepreneurial activity, of intellectual property rights and of the network of relationships with actors having complementary knowledge and assets (other firms, universities and public research centres, parent organisation). The analysis finally highlights interesting differences both at the geographical and sectoral level. Differences across geographical regions include the degree of development of financial markets and the opportunities to access external financial resources, but also and mostly the functions performed and the effectiveness of the university system. On the other side, differences across sectors include the assets exploited in founding the new venture and the key competences that allow it to survive and eventually grow.

Le strategie dellěinnovazione. Indagine sui brevetti europei delle imprese italiane
Authors: Ramella Francesco , Trigilia Carlo 
Published: July 2021

- In international rankings on innovation Italy's position is particularly weak. Is this image realistic? A recent survey on Italian firms that applied for European patents (EPO) between 1995 and 2004 casts some doubts on this ranking. The article describes the results of the survey and outlines the Italian geography of innovation. The key assumption of the study is that the "patenting potential" of firms and territories depends on their ability in the "social construction" of innovation. In other words, it depends on the effective integration between human and social capital of firms, on the one hand, and collective goods and resources from the local (and non-local) context, on the other. Research results show that: 1) the Italian system of innovation is less weak than usually believed, even in the high technology sectors, and especially in the central and northern regions; 2) in Italy, there are two different territorial and sectoral systems of innovation (the first system is that of mechanics, with its basis in the North-East-Centre; the second one is that of high technology, with its basis in the North-West); 3) these innovation systems are territorially concentrated; 4) what differentiates the most innovative local economic systems is the high endowment of collective goods and universities; 5) the Italian policies for innovation are inadequate, since they tend to neglect the relational and systemic components of innovation. .

Tendenze degli investimenti diretti esteri dopo la crisi finanziaria: che accade?
Authors: Mariotti Sergio 
Published: July 2021

- This article investigates the recent trends in FDIs, focussing on the effects provoked by the financial crisis. The crisis has impacted in a significant manner on the more volatile component of FDIs, i.e. cross-border M&As. On the contrary, forecasts for greenfield FDIs are just in line with the decline expected in world export, after a strong increase registered in 2008. With the possibility that the financial crisis could catalyse a trend toward the so called "reverse globalization", the paper argues that there is evidence of an increasing heterogeneity in firms' behaviour, with some firms now considering whether or not to scale back offshoring production by returning operations to, or closer to, home. Nevertheless, there is no evidence, or at least not yet, that we are witnessing a major shift in the direction and dynamics of international delocalisation processes.

Fondi sovrani: opportunitŕ, minacce, speranze e illusioni
Authors: Bertoni Fabio , Lugo Stefano 
Published: July 2021

- In this work we provide a critical summary of the debate about sovereign wealth funds (SWFs). We start by explaining what a SWF is and what it is not according to the various definitions that have been proposed. We then present the main concerns and hopes which SWFs have raised and explain why these threats and opportunities are often exaggerated, incorrect or, at the best, not yet supported by any serious empirical evidence. We devote particular attention to the issue of the transparency of SWFs and show that, while there still is ample room for improvement, SWFs are clearer now than what they used to be before the Santiago principles were signed. We also point out, however, that there are sound reasons to believe that transparency, if pushed too far, could be detrimental to both SWFs and recipient countries. Finally, we present the results of the first attempts made by academics and practitioners to provide systematic evidence on SWF investment behaviour.

Negli ultimi anni, prendendo le distanze dal modello strutturale delle pulsioni e dall'idea tradizionale di un apparato mentale isolato spinto fondamentalmente dai compromessi tra forze interne conflittuali, diversi studiosi (Mitchell, 1988; Aron, 1996) hanno posto l'accento sui processi interpersonali, nel senso che la crescita e il formarsi delle funzioni psichiche dipendono dal tipo e dalla qualitŕ dell'

I partner coinvolti in una relazione sentimentale organizzerebbero cioč una loro reciproca e specifica capacitŕ di regolare gli stati emotivi, per ottenere un certo equilibrio interno tra senso di "distanza e vicinanza". In quest'ottica il lavoro odierno con le coppie deve considerare l'uso che i partner fanno della relazione rispetto alla funzione di reciproca auto ed etero regolazione e i processi che vengono messi in atto per raggiungere questi obiettivi.
Il nuovo paradigma della psicoanalisi infantile: l'importanza del "procedurale" in un approccio terapeutico integrato
Authors: Busso Emanuela 
Published: July 2021

Il testo traccia le linee generali di un nuovo paradigma dalla psicoanalisi infantile, definito "Approccio terapeutico integrato". Il modello nasce all'interno della teoria dei sistemi complessi e tiene conto dei dati dell'
e delle scoperte neuro scientifiche sulla memoria procedurale. Si tratta di un intervento ad orientamento psicoanalitico sulle diverse componenti del sistema genitori-bambino, sistema che si estende ad altre persone significative per il bambino e di cui entra a far parte l'analista. L'intervento clinico, articolato su più livelli (interattivo, relazionale e intrapsichico), è caratterizzato dal coinvolgimento dei genitori nel processo terapeutico, dall'elasticità della tecnica e dall'utilizzo del gioco come espressione del sistema bambino-genitori-analista. Nelle vignette cliniche proposte, i bambini in seduta fanno apparentemente lo stesso gioco, ma con significati molto diversi in ogni singolo caso. L'analista non interpreta il contenuto del gioco, ma il lavoro terapeutico si svolge in gran parte su un livello implicito, procedurale del "come si gioca e si sta insieme". Ogni cambiamento nel modo di giocare segnala ed esprime un cambiamento nel sistema bambino-genitori-analista.

A polêmica sobre o conceito de terceirização e sua regulação
Authors: Dutra Renata , Filgueiras Vitor 
Published: July 2021

Apesar de a terceirização ser objeto de grandes controvérsias, existe um consenso acerca do conceito que a define. O objetivo deste texto é problematizar esse consenso e apontar suas contradições, demonstrando que a precarização do trabalho relacionada à terceirização não é uma contingência, mas corolário da natureza dessa forma de contratação de trabalhadores, que reduz as chances de limitação da exploração do trabalho.

Temperature Effect on the Physical Properties of Enamel Paint Layer on Cement Plaster
Authors: Kaiser Samiul , Kaiser Mohammad Salim 
Published: July 2021

The heating effect on the stability and visual colour of enamel paint on cement plaster is evaluated through light intensity ratio of three primary colours (RGB). The painted cement plaster is isochronally heated in an electric resistance furnace at different temperatures for one hour. The investigation of optical images reveals that the original colour of the paint layer on the plaster samples remains more or less unchanged up to heating at 100°C. However, thermal degradation of the samples becomes evident in colour when they are heated beyond 200°C and at 350°C the colour becomes already burned. The microstructural images of the samples at room temperature show fine and uniform grains. But at higher heating condition the microstructure of the colour sample is characterized by coarsening grain. The colour of the heated samples are then studied through tristimulus colour ‘L*’, ‘a*’ ‘b*’ and ‘E*’ values which were analyzed and evaluated in MATLAB software. The results show that after 200°C the hunter ‘L*’ value starts to decrease greatly up to 250°C. The hunter ‘a*’ value shows an increasing trend up to 100°C and then begins to decrease until 200°C. After 200°C the same increasing character is showed till 300°C. The change of hunter ‘b*’ value remains insignificant up to 100°C and shows decreasing trend between 100°C-250°C range and an increase after 250°C up to 300°C. It is graphically shown that the proportion of all three colours decreases with the increasing temparature. The overall change of colour ‘E*’ occurs with increasing heating temperature due to moisture releasing, chemical changes and thermal degradation simulteneously. The thickness of enamel paint layer comply the above degradation by showing the nature of decresing trend.

Modified Dynamically-updated Weighted Opportunity Cost Based Algorithm for Unbalanced Transportation Problem
Authors: Jamali ARM Jalal Uddin , Mondal Ringku Rani 
Published: July 2021

Recently, Weighted Opportunity Cost (WOC) based algorithms are developed for solving balanced Transportation Problems (TPs). The exceptionality of the WOC based approaches is to introduce supply and demand as weight factor to cost entries for the control of flow of allocations. But in the unbalanced TP, there exist a pitfall whenever balancing the TP with zero dummy transportation cost as done in existing classical approaches, so that the total cost is unaffected due to dummy transportations. A modified dynamically-updated weighted opportunity cost-based algorithm embedded on Least Cost Method (LCM) is proposed which is suitable for both balanced and unbalanced TPs. Numerical instances have been carried out to demonstrate the effectiveness and efficiency of the proposed method. It is observed that, the proposed modified dynamically-updated weighted opportunity cost-based algorithm sometimes outperforms for the LCM as well as the existing weighted opportunity cost-based algorithm in unbalanced TPs.

nutria marina (Lontra felina) en los Andes del sur del Perú
Authors: Ugarte Núñez Joaquín Antonio 
Published: July 2021

La nutria marina, gato marino o chungungo (Lontra felina) es considerada virtualmente una especie exclusiva marina con una preferencia de hábitat rocosos de litoral en la costa pacíﬁca de Perú y hasta Tierra del Fuego al sur de Chile y la Isla de los Estados en el sur de Argentina. En esta nota cientíﬁca se presentan registros ﬂuviales de la nutria marina. En el río Cotahuasi (cuenca del río Ocoña) se tiene un registro hasta la localidad de Sipia, a 171 Km del litoral y a 1 994 m de altitud. En la cuenca del río Colca (cuenca Majes), el registro más alejado es en la laguna Mamacocha en la provincia de Caylloma, a 157 Km del mar a una altitud de 1 702 m.Se presentan además otros registros directos e indirectos hasta la desembocadura de estas cuencas. El registro de esta especie en dos de los ríos más grandes del suroeste de Perú y no en los demás (departamentos de Moquegua y Tacna), posiblemente se deba a la conﬁguración extremadamente encañonada, lo que puede representar un refugio para esta especie amenazada, además de tener una abundante oferta alimenticia. Se considera necesario incluir acciones de conservación en la distribución ﬂuvial de la nutria de mar, debido a que actividades como la construcción de presas, afectarían signiﬁcativamente su presencia en este espacio y hábitat de su distribución, en gran medida desconocido.

Introduction: Non infectious disease is a major health problem especially in developing countries. Among those, stroke always be the leading one that occurs followed by health burden. Some factors in increasing of mortality and disability due to stroke are lack of understanding of risk factors and awareness to early signs especially among people with hypertension. If the factors those influence the knowledge, awareness, and others stroke alert behaviors are known, promotive or prevention acts could be done by health workers. Aims: The aim of this study is to find out the stroke alert behavior among them that conducted at Puskesmas Cengkareng of West Jakarta on July and August 2020. Method: 116 patients were participated to fill the questionnaire and analyzed with cross-sectional design. Results: Our study revealed that knowledge, perception of utility, and perception to level of disease severity is the most influenced factor to stroke alert behavior.
Obstructive Sleep Apnea Increases the Risk of Perioperative Myocardial Infarction Following Off-Pump Coronary Artery Bypass Grafting

Published: July 2021

Background and Aims: The impact of obstructive sleep apnea (OSA) on perioperative myocardial infarction (PMI) following coronary artery bypass grafting (CABG) remains unclear. Off-pump CABG (OPCABG) has become a common practice for CABG in China. The present study investigated mainly the correlation between OSA and PMI following OPCABG.Methods: In this prospective observational single-center study, consecutive eligible patients listed for elective OPCABG underwent cardiorespiratory polygraphy before surgery between January 2019 and June 2020. OSA was defined as an apnea-hypopnea index (AHI) ≥15 events/h. The primary end point was perioperative myocardial infarction (PMI) following OPCABG (type 5 MI).Results: Patients with OSA accounted for 42.2% (62/147) of the cohort. Twenty-four patients (16.3%) met the protocol criteria for PMI: 17 (27.4%) in the OSA group and 7 (8.2%) in the non-OSA group (P = 0.002). Multivariate logistic regression analysis revealed that AHI (OR = 1.115, 95% CI 1.066 to 1.166, P &lt; 0.001), high-sensitivity c-reactive protein (hs-CRP) (OR = 1.080, 95% CI 1.025 to 1.138, P = 0.004), and SYNTAX score (OR = 1.098, 95% CI 1.056 to 1.141, P &lt; 0.001) were associated with PMI incidence. Furthermore, ROC analysis revealed that the AHI (AUC = 0.766, 95% CI 0.689 to 0.832, P &lt; 0.001) and SYNTAX score (AUC = 0.789, 95% CI 0.715 to 0.852, P &lt; 0.001) had predictive value for PMI. In addition, multiple linear regression analysis showed that the AHI was an independent influencing factor of hs-CRP (B = 0.176, 95% CI 0.090 to 0.263, P &lt; 0.001) and the SYNTAX score (B = 0.553, 95% CI 0.397 to 0.709, P &lt; 0.001).Conclusions: OSA was independently associated with a higher incidence of PMI following OPCABG, and the formation of severe coronary atherosclerotic lesions aggravated by an enhanced inflammatory response might be the potential mechanism. The efficacy of CPAP treatment for improving prognosis after CABG remains to be further investigated.

Published: July 2021

BackgroundThe association between adiposity and papillary thyroid carcinoma (PTC) has been reported in several studies, but its association with aggressive clinicopathologic features is not well-recognized. Our aim is to systematically review the literature to identify whether adiposity, expressed through Body Mass Index (BMI), is related to aggressive clinicopathologic features such as tumor-node-metastasis (TNM) stage, extrathyroidal extension (ETE), lymph node (LN) metastasis and multifocality in patients with PTC.MethodsA systematic search for articles was performed using the PubMed, EBSCO, and Cochrane Library for all articles published in English until December 2020. Specific keywords such as “papillary thyroid carcinoma”, “Body Mass Index”, “clinicopathologic features” were used in the search strategy. Two independent reviewers screened all retrieved articles based on predefined inclusion and exclusion criteria. Meta-analysis was performed in the studies that reported crude and adjusted odds ratios (OR). The methodological quality was assessed using the Newcastle-Ottawa Scale.ResultsA total of 11 retrospective cohort studies involving 26,196 participants included. Our findings showed that elevated BMI was significantly associated with ETE in both overweight (OR 1.26, 95% CI: 1.09-1.44) and obesity group (OR 1.45, 95% CI:1.26-1.64). Elevated BMI was also significantly associated with multifocality in overweight patients (OR 1.17, 95% CI:1.10-1.24) and obese patients (OR 1.45, 95% CI:1.29-1.62). Also, obesity was significantly associated with increased tumor size (OR 1.77, 95% CI:1.52-2.03) and with LN metastasis (OR 1.28, 95% CI: 1.12-1.44), whereas being overweight was significantly associated with advanced TNM stage (OR 1.55, 95% CI:1.27-1.83) ConclusionOur results provide strong evidence for the association between higher BMI and ETE, multifocality, and tumor size. Further studies with a larger number of participants are required to elucidate further the association of increased BMI with advanced TNM stage and LN metastasis.
Dry Eye and Phacoemulsification Cataract Surgery: A Systematic Review and Meta-Analysis
Authors: Lu Qiang , Lu Yi , Zhu Xiangjia 
Published: July 2021

Purpose: To evaluate whether dry eye deteriorates after phacoemulsification cataract surgery, and to explore the influential factors.Methods: Studies published before February 2020 indexed on PubMed and the Cochrane Central Register of Controlled Trials were retrieved. A meta-analysis, including meta-regression, a sensitivity analysis, and a subgroup analysis, were performed.Results: Twenty studies with 2,247 eyes were included in the meta-analysis, dry eye-related parameters were investigated preoperatively and 1 month postoperatively. Patients with pre-existing meibomian gland dysfunction (MGD) had worsened subjective symptoms of dry eye (1.31, 95% confidence interval (CI) [0.66, 1.95], P &lt; 0.0001), a reduced tear break-up time (BUT) (−2.27, 95% CI [−2.66, −1.88], P &lt; 0.0001), and a worse corneal fluorescein staining (CFS) score (0.75, 95% CI [0.5, 1.0], P &lt; 0.0001) after phacoemulsification cataract surgery, whereas in the general population, the subjective symptoms score and CFS remained unchanged and BUT decreased slightly after surgery. Patients without diabetes showed significantly reduced total tear secretion after phacoemulsification cataract surgery (−1.25, 95% CI [−1.62, −0.88], P &lt; 0.0001).Conclusion: Dry eye generally remained unchanged 1 month after phacoemulsification cataract surgery. Notably, worsened symptoms and signs of dry eye were observed more frequently in patients with pre-existing MGD. Patients without diabetes were more susceptible to reduced tearing postoperatively.Clinical Trial Registration: Identifier: PERSPERO (2020: CRD42020203316).
