The emotional and psycho-social consequences of coronavirus disease-19 pandemic – A glimpse into the post-pandemic society
Authors: Chhabra Smrithi
Published: October 2020

The coronavirus disease (COVID-19) pandemic has swept across the globe so devastatingly causing high morbidity and mortality and has brought in its wake, not only social and economic problems but also a myriad of psychological problems which if not addressed properly may contribute considerably to a significant loss of productivity in the society. As per the saying “A sound mind in a sound body,” physical and mental health is equally important and interdependent on each other. In the present scenario, unfortunately, with people suffering from physical illnesses, as well as devastating mental sequelae of the pandemic has resulted in social, financial, economic, and emotional uncertainties. Therefore, it is most important to identify and to treat the mental health problems faced by general population, quarantined people, health-care professionals, at-risk-groups, and the victims of COVID-19 pandemic. The mental health problems can be in the form of depressive disorders, various anxiety disorders, stress related disorders, suicide and intentional self-harm, grief reaction, substance abuse (alcohol, tobacco, cannabis, and opioids), and domestic violence. Although, limited resources available to us during these difficult times, this should not dissuade us from ensuring optimal mental health and trying to keep the struggling humanities “sane” during this pandemic. These resources must be used judiciously and appropriately, with necessary modifications (telephonic/audio-video consultations and counseling) to prepare a society which can move forward in the post pandemic era.

Authors: Bansal Manishi , Jindal Ankush , Gupta Smriti
Published: October 2020

Introduction: Nephrectomy is a common surgical procedure for wide variety of renal diseases, including both benign and malignant conditions. The causes of nephrectomy may vary with different geographical areas and institutions. A thorough histopathological analysis of nephrectomy specimens abets formulation of treatment guidelines specific to the geographic area. Objective: The objective of the study was to analyze trends and patterns of renal diseases requiring nephrectomy and to observe variations from the conventional pattern or geographic variation, if any. Methods: A hospital-based study was carried out to study and analyze histopathology of 38 nephrectomies done during the period of 2 years (January 2018–December 2019) at Mayo Super Specialty Hospital, Mohali, Punjab. Results: Out of 38 nephrectomies, 20 were benign and 18 were malignant. Malignant lesions were more prevalent in older age groups. Chronic pyelonephritis was most common cause of benign lesions. We observed loss of corticomedullary junction and dilatation of pelvicalyceal system in more than 80% of cases. Among malignant conditions, clear cell renal cell carcinoma was the most common histology. The World Health Organization/the International Society of Urological Pathology Grade 1 was the most common among the malignant lesions and only one case of sarcomatoid differentiation (Grade 4) was seen. Conclusion: The present study provides a detailed histopathological analysis of nephrectomies done at our institute and gives a reflection of the clinical spectrum in this part of India.

Authors: Dutta Meghna , Chatterjee Suddhasatwya , Zoha Sraboni Ghosh , Ramasubban Suresh
Published: October 2020

Toxic epidermal necrolysis (TEN) is a potentially life-threatening dermatologic disorder characterized by widespread erythema, necrosis, and bullous detachment of the epidermis of skin and mucous membranes, resulting in exfoliation and possible sepsis and/or morbidity/mortality. Exact diagnosis of lesions is very important in terms of therapeutic intervention as well as outcome. As cutaneous hypersensitivity reactions are known to occur with increased frequency in connective tissue disease, differentiating lesions of systemic lupus erythematosus that simulate drug-induced TEN is a challenge in the practical scenario. In this case series, we discuss about three patients aged between 24 and 67 years, who presented with vesiculobullous lesions all over the body and oral mucosal ulcerations. Each of them was initially admitted in the Critical Care Unit with a provisional diagnosis of TEN. Two of the three patients recovered well and were discharged. However, the third patient, who was the oldest and had multiple comorbidities, could not be saved and succumbed after 75 days of hospital stay.

Published: October 2020

Non-Hodgkin’s lymphoma (NHL) is malignancies of white blood cells called lymphocytes. Although fever and weight loss are the main symptoms associated, NHL is known for its unusual presentation. Variants of NHL include diffuse large B cell, Mantle cell, Burkitt’s Lymphoma, Precursor B cell type, and among many. At times, paraneoplastic diseases often mask the underlying lymphoma and hence delaying the diagnosis. Through this case series, we discuss the association of NHL with paraneoplastic diseases. NHL was associated with dorsal myelitis in the first case, metastatic spread in abdomen in the second case and with Steven Johnson syndrome in the third case.

Authors: Gera Akriti , Singh Amitabh , Sungadhi Nidhi , Aggarwal Nidhi , Gera Rani
Published: October 2020

Background: The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has affected the world at large. To control the spread of the virus, the Government of India promoted simple measures such as social distancing and hand hygiene. Yet, the most prominent one was a strict nationwide lockdown on all non-essential services and complete curtailment of the public transport. Objective: Our study aims to quantify the impact of COVID-19 pandemic and lockdown measures on the pediatric services of a tertiary care center in North India. Materials and Methods: A retrospective observational study was done to analyze the change in our outpatient visits, admissions, and number of institutional deliveries, immunization services, pediatric surgeries, and mortality rates during the lockdown period when compared to the pre-lockdown period. Data of all children aged 0–12 years who presented to the pediatric medicine and pediatric surgery departments were collected. Data were divided into two groups; January 1, 2020–March 31, 2020 and April 1, 2020–June 30, 2020. Results: There was a reduction of 79.1% OPD attendance and 70.8% in immunization visits. Inpatient admission in pediatrics medicine and surgery decreased by 59.8% and 67.6%, respectively. The mortality rate increased from 11.8% to 13% and 7.6% to 19.6%, respectively. Emergency area visits decreased by 55.3% with an increase in mortality rate from 2.4% to 6.2%. Intramural births decreased by 55.4%. Conclusion: The COVID-19 pandemic has led to an unmet need of pediatric services. This requires urgent management or else it may halt the progress made in different aspects of health care.

Published: October 2020

Background: Neonatal sepsis (NS) is a clinical syndrome characterized by signs and symptoms of infection with or without bacteremia in neonatal age. At present, there are a variety of tests available for testing sepsis in neonates including C-reactive protein (CRP). Objective: The objective of the study was to decrease the antibiotic duration in a case of NS and to decrease the hospital stay and financial burden on the patient by measuring serial CRP levels. Materials and Methods: This case–control study was conducted in a tertiary care teaching hospital at a tertiary hospital of central India. A total of 103 neonates were considered as the study population. Estimation of serial CRP levels among neonates was assessed and correlated within two study groups. Results: CRP level at admission was able to successfully identify NS in 66.67% of the cases (sensitivity), while in 12.07% it was able to negate NS when it was absent on blood culture also (specificity). The positive predictive value (PPV) was low (37.04%) with a negative predictive value of 31.82%. The diagnostic accuracy of the CRP level at admission was 35.92% suggesting its accuracy to correctly identify the patient with NS in only 35.92% cases. The results show that CRP is having a good sensitivity, with a poor specificity, and overall low diagnostic accuracy. Conclusion: Our study showed a significant difference in the use of antibiotics in the two groups. The sensitivity of CRP was high with the low specificity and low PPV and high NPV, which makes CRP a vital screening tool, especially if used in conjunction with other screening parameters improving the overall sensitivity and specificity.

Authors: Syaira Arlizar Ritonga
Published: October 2020

Penelitian ini berjudul Proses Komunikasi Antarpribadi Orangtua dalam Mengenalkan Pendidikan Seksual kepada Anak Autis di Kota Medan. Penelitian ini bertujuan untuk mengetahui bagaimana proses komunikasi antarpribadi orangtua dalam mengenalkan pendidikan seksual kepada anak autis di kota Medan. Penelitian ini menggunakan pendekatan kualitatif dengan metode penelitian fenomenologi. Hasil penelitian menunjukkan bahwa proses komunikasi antarpribadi yang terjalin antara orangtua dan anak autis adalah bersifat dua arah. Namun respon balik yang diberikan oleh anak autis tidak selalu berbentuk ucapan langsung, tetapi mereka lebih sering menggunakan tindakan. Hal ini dikarenakan sulitnya bagi mereka untuk berkomunikasi karena mengalami gangguan dalam mengolah kata-kata (speech delay). Pesan ataupun instruksi yang disampaikan oleh orangtua dan guru mampu ditangkap dan diterjemahkan dengan baik di dalam pikiran mereka. Proses komunikasi antarpribadi orangtua dalam mengenalkan pendidikan seksual dipengaruhi oleh kedekatan dan pengemasan pesan yang sederhana sehingga membuat mereka lebih mudah memahami. Peran orangtua sangat dibutuhkan dalam mengenalkan pendidikan seksual kepada anak autis. Selain itu, guru juga bisa membantu peran orangtua dalam mengenalkan pendidikan seksual ketika di sekolah. Proses komunikasi antarpribadi yang baik dan efektif sangat mempengaruhi perubahan sikap dan pengetahuan anak autis tentang pendidikan seks tersebut.

Керування напружено-деформованим станом в’язкопружних тіл із циліндричною анізотропією, що складаються з багатьох шарів та армовані є дуже важливим на практиці, зокрема, у будівництві. Розв’язання задач механіки анкерних стрижнів та фундаментів на палях на сьогодні залишається дуже актуальним. Результати також можуть бути корисними при аналізі напружено-деформованого стану волокнистого композиту. У роботі розглядається складна просторова осесиметрична контактна задача про передачу навантаження від стержня кругового поперечного перерізу до в'язко-пружного тіла, що складається з двох скріплених між собою ортотропних шарів з циліндричною анізотропією. Визначається закон розподілу контактних напружень між стрингером та тілом, а також зусилля в стрингері при умові його навантаження в кінцевих точках поздовжніми силами. Для розв’язання використовується розроблений авторами асимптотичний метод. У якості малого параметра обирається відношення жорсткісних характеристик матеріалу. Оскільки матеріал тіла в’язкопружний, цей фізичний параметр включає в себе відношення функцій, що виникають після застосування перетворення Лапласу в основних рівняннях і залежать від параметру цього перетворення. Такі відношення для в’язкопружних анізотропних матеріалів, що зазвичай розглядаються на практиці, не перевищують одиницю і тому параметр асимптотичного інтегрування лишається малим. Такий вибір малого параметру є зручним, оскільки вигляд рівнянь та крайових умов, записаних відносно трансформант Лапласа, повністю співпадає з відповідними виразами для пружної постановки задачі. Після розв’язання задачі в такому вигляді, лишається питання переходу до оригіналів шуканих функцій. Такий перехід можна спростити, якщо знаходити оригінали для малих та великих значень обраних параметрів (наприклад, часу), а потім з’єднати їх за допомогою двоточкової апроксимації, що дозволяє отримати загальний розв’язок.

Published: October 2020

Розроблено математичну модель частотного параметричного перетворювача вологості з ємнісними елементами виготовленими на основі: NaCl+полімер, NaCl; BaCl2+полімер, BaCl2, а також ємнісних елементів виготовленими на основі комплексних сполук. Параметричний перетворювач вологості з частотним виходом розроблено на основі біполярної транзисторної структури, що утворює активну індуктивність з динамічним від’ємним опором, яка з вологочутливим конденсатором СW утворює коливальний контур перетворювача. Математичне моделювання та експериментальні дослідження показали, що в діапазоні відносної вологості від 30 % до 100 %, діапазон зміни ємності для вологочутливого елементу на основі NaCl становить від 0,030·10-8 Ф до 3,9·10-8 Ф, а для двошарової структури на основі NaCl+полімер – від 0,125·10-8 Ф до 3,9·10-8 Ф. Для вологочутливого елементу на основі BaCl2 – діапазон зміни ємності становить від 0,060·10-8 Ф до 3,9·10-8 Ф, а для двошарової структури на основі BaCl2+полімер – від 0,130·10-8 Ф до 3,9·10-8 Ф. На основі експериментальних досліджень встановлено, що на чутливість сенсора впливає склад комплексних сполук, а саме найчутливішим в діапазоні вологості від 7 % до 27 % є ємнісний елемент виготовлений на основі гетерометалевої комплексної сполуки II, яка містить два атома стибію. Чутливість такого ємнісного елемента набуває значення 285 пФ/%. Залежність ємності від відносної вологості, в діапазоні від 30 % до 75 %, практично лінійна, а чутливість дорівнює 135 пФ/%. В діапазоні 75…95 % спостерігається різке зростання чутливості аж до 450 пФ/% для всіх ємнісних елементів виготовлених на основі гетерометалевих комплексних сполук I – IV. На основі математичного моделювання отримано графічні залежності функції перетворення та чутливості частотного параметричного перетворювача вологості. Найбільша чутливість частотного параметричного перетворювача вологості для зміни вологості навколишнього середовища становить 62…107 кГц/%.

Published: October 2020

У даному дослідженні розроблені комбінована геометрична модель та оптимізаційний підхід для визначення параметрів недоступної точки об'єкта. Виявлено проблему і поставлені першочергові задачі. Суть проблеми: об'єктивне протиріччя між необхідністю отримання точного значення потрібного параметра і наявністю похибок при будь-якому вимірюванні. Мета дослідження – розробити комплексно комбіновану тривимірну геометричну і аналітичну моделі визначення мінімальної області значень параметрів недоступної точки об'єкта. Завдання статті: 1. Розробити комбіновану тривимірну геометричну модель з перехресними візирними променями для безконтактного визначення координат недоступної точки об'єкта при заданому розташуванні геодезичного обладнання. 2. Розробити оптимізаційну аналітичну модель визначення області значень параметрів недоступної точки об'єкта відповідно до запропонованої тривимірної геометричної моделі з перехресними візирними променями. У запропонованому оптимізаційному підході розроблена комбінована тривимірна геометрична модель з перехресними візирними променями для визначення координат недоступних точок об'єкта. Обумовлена точка C розташовується в області [CDM, CEM] мінімальної відстані ρmin між перехресними візирними променями. Оптимізаційна задача визначення координат недоступної точки об'єкта в просторі зводиться до задачі визначення мінімальної відстані між двома перехресними візирними променями. Завдання має єдине рішення, якщо візирні промені не паралельні. Пошук екстремуму функції відстані між двома візирними променями, і саме мінімуму, має реальну геометричну інтерпретацію. Функція відстані ρ=f(tCD, tCE) досягає свого екстремуму ρmin, коли її часткові похідні по кожній змінній дорівнюють нулю. Тому вирішується система диференціальних рівнянь. Шукана точка C(xC, yC, zC) може, наприклад, розташовуватися в середині мінімального відрізка [CDM, CEM]. Запропонований теоретичний підхід перевірений на реальних даних при відновленні Спасо-Преображенського собору в місті Одесі, Україна. Визначалися координати найвищої точки колони пілястра С і точки С' рівня землі відносно горизонтальної площини з нульовими візирними променями.

Un nuovo modello per l'agricoltura in Valle di Non, fra risparmio idrico e tutela ambientale
Authors: Zambotti Alberto
Published: October 2020

The southern slopes of the Alps are facing a changing climate. This is acutely perceived in areas ideally suited to highquality agriculture, such as the Val di Non, in the northern Italian Province of Trento. Here agriculture has been constantly improving in technology and management. Drip irrigation now covers 100% of fruit tree cultivation, notably apple and cherry representing 90% of the over 8,000 hectares of farmed land.Cooperative management of resources, both in irrigation and land management, underpins and strengthens the agricultural sector in the Province of Trento. The Province's primary legislative control over agriculture and environmental protection maximizes the legislator's closeness to the interests and needs of agricultural producers and economic actors. This article illustrates the norms regulating agriculture and environmental protection in the Province of Trento. Secondly, it presents the ongoing complex research aimed at striking a new balance between environmental concerns (namely, the preservation of the quality of water streams in Val di Non) and growing demand for water for local agricultural production. The needto provide adequate water supply for agriculture conflicts with the necessity to guarantee minimum flow levels in local water streams, as provided for by law (environmental flow), as well as to preserve adequate quality of flowing water. The article proposes to connect existing irrigation infrastructure – irrigation networks, reservoirs and pumping stations. Itanalyzesa range of issues – parasite management; insurance against spring frost; labor protection; processing and marketing of produce. It connects with local research centers – the University of Trento for climatological research, the Mach Foundation for agronomic research and the Kessler Foundation for the application of new technologies to data harvesting and management.

L'autore, professore di Psicologia Dinamica presso l'Università di Bergamo, si è ammalato per coronavirus ed è stato ospedalizzato per due settimane. Ancora in quarantena a casa sua scrive questa testimonianza e ce la invia, mentre viene prontamente pubblicata online da Eu-ropean Journal of Psychoanalysis . La testimonianza dell'autore muove verso eclettiche ri-flessioni che mettono in connessione virus e inconscio. L'autore rileva in presa diretta quanto l'esperienza d'impotenza catastrofica includa ed imponga la sottrazione del sistema inconscio dal dominio del controllo umano.
L'inatteso non è l'inevitabile
Authors: Quaglino Gian Piero
Published: October 2020

Il mondo degli eventi è il mondo nelle tre dimensioni dell'Incerto, dell'Inatteso e dell'Inevitabile. Ciò che consideriamo inevitabile può essere talvolta nient'altro che un difetto di "padronanza" dell'inatteso. Coltivare capacità di riflessione e di immaginazione è dunque indispensabile per saper pensare il mondo degli eventi con ampiezza di campo e chiarezza di sguardo, con lucidità di visione. Saper pensare, come traguardo di formazione, significa però non solo "mente lucida", ma anche "psiche solida" e "spirito sereno". La psiche solida richiede approfondita conoscenza dei sentimenti che ci abitano e ci animano (è "educazione sentimentale"). Lo spirito sereno richiede pratica sapiente del fondamento etico che guida il cammino nella vita: cioè nel mondo di ciò che "accade" nelle tre forme dell'Incerto, dell'Inatteso e dell'Inevitabile.

Il diritto di seguito nel mercato dell'arte contemporanea
Authors: Stabile Silvia
Published: October 2020

Oggi il mercato dell'arte contemporanea è sempre più globale e si assiste ad una crescente delocalizzazione delle vendite verso Paesi in cui il diritto di seguito non è previsto dalla legislazione nazionale. L'articolo affronta le origini del diritto di seguito (droit de suite) in Francia, alla fine del 1800, la sua introduzione, a livello internazionale, con la Convenzione di Berna e, infine, nei Paesi dell'Unione Europea con la Direttiva 2001/84/CE. L'articolo inoltre descrive, in sintesi, il quadro normativo relativo al diritto di seguito in Italia, distinguendo tra mercato dell'arte primario e secondario, per poi affrontare la proposta di riforma della legge sul diritto d'autore della Repubblica Popolare Cinese e i più recenti dibattiti all'interno della comunità dell'arte degli Stati Uniti d'America. In conclusione, è presentata una soluzione alternativa per gli artisti di quei Paesi che non riconoscono il diritto di seguito: la previsione contrattuale della royalty nell'accordo con l'artista per ogni rivendita delle sue opere d'arte.

Authors: Sidoti Enza , Palma Silvia , Marrali Lorenzo
Published: October 2020

This paper describes the results of an exploratory survey aimed to examine the experience of a group of special needs teachers on the use of ICT in teaching to students with autism spectrum disorder. It is focused on the effectiveness of video modeling as a tool through which to learn (self-learning and imitation) specific skills in the field of personal autonomy. By sharing the thought of Rossi (2012), which has stated that "digital technologies provide to school an extraordinary opportunity to put on the agenda the issue of learning and, together with it, the professionalism of teachers", the authors handed out a questionnaire to a group of special needs teachers of a Comprehensive School in Palermo with the purpose to investigate the perceived effectiveness experienced in the use of ICT for the achievement of different learning objectives and on critical issues. This work offers a detailed analysis of the investigated areas and the results from the survey, proposing a critical reflection on the emerged issues.

Apprendimento e Insegnamento nella prospettiva dell'Enattivismo
Authors: Damiano Elio
Published: October 2020

This article deals with one of the structural problems of Enaction, namely , which had already been the target of criticisms that were directed against its early (remote) anticipations in Edmund Husserl's Phenomenology, and is the raison d'être of internal corrections such as  (Einfühlung) and the . In particular, in the context of educational research, the focus on the subject produces a  that involves the overturning of Learning on Teaching, as the use of categories such as ,  and  demonstrates. Enaction can exit from this contradiction, while maintaining its own framework, by re-calling knowledge that the ‘subject-teacher' builds through the action of teaching and the resistances opposed  by the ‘subject-pupil'.
Peer assessment and gamification: a university teaching experience in a course of Media Education
Authors: Bruni Filippo
Published: October 2020

Attention towards university teaching is growing, also as a result of the evaluation procedures aimed at the Italian university system. In this context, the experience of the course of Media Education and digital literacy activated during the degree course in Communication Sciences at the University of Molise is presented. Given the need to acquire not only knowledge but digital literacy, students were asked to create digital products using a dual methodological approach: gamification and peer evaluation. The gamification has allowed to conceive the activities of the course as a series of challenges to which to give a timely response, as documented by the blog of the course https://ilblogcialafebbre.blogspot.com/.  The peer assessment allowed to increase the interactions among the students, pushing to forms of analysis and comparison that have had positive repercussions on the realized digital products. In evaluating the overall experience, despite the difficulty in interpreting the available data, the perspective of  linking the gamification processes to the creation of assessment rubrics is affirmed
Taxonomy of curriculum change models: the case of Problem Based Learning
Authors: Lotti Antonella
Published: October 2020

The idea, proposed in this work, is that who are introducing educational innovation in University teaching should focus more on the renewal of a curriculum more than in a single course's changes. University teaching innovation  often focuses on the changes introduced within a single discipline through the adoption of some educational technologies or new teaching-learning-evaluation methods,  keeping the focus only on the single discipline and not on the curriculum as a whole. With reference to the work of  Ronald Harden about the eight roles of the university teacher, we underline  the role of  Curriculum developer and implementer. Six models are proposed to classify the introduction of innovative curricula. The different ways by which Problem Based Learning was introduced in university curricula are described  as  examples of the six models.

Costruire infiniti mondi professionali. Prospettive trasformative
Authors: Fabbri Loretta , Romano ,Alessandra
Published: October 2020

Young people, future, endless worlds are the key words that question the professional epistemology of the university faculty and the university itself as an organization. The thesis: the title intercepts the core problem that the academic community has been investigating for the recent years, namely the professionals who work within the organization called university. University right now is addressing the prefiguration of possible futures for itself as organization of research and training for the students. One of the main missions of higher education system is to prepare young people to face the challenges of the future. The question we want to stress here is how the university is gearing up to be an active agent in promoting the trajectories of the future society. And above all which conditions could hinder or facilitate its role of agency-orientation (Rieckmann, 2011).
Educazione emotiva e linguaggio interculturale
Authors: Di Giusto Anna
Published: October 2020

La presente ricerca nasce dal tentativo di rispondere all'urgenza, sempre più avvertita nella scuola italiana a forte impronta multiculturale, di individuare una modalità di risposta a uno dei principi cardine dell'educazione, ovvero quello dell'accoglienza. Sulla linea di pensiero della Scuola di Barbiana, ripresa e approfondita anche dal convegno SIPED tenutosi a Catania nel 2014, il progetto si è proposto di dare corpo a una nuova forma di pedagogia militante. Con questo termine si intende la messa in atto di una sperimentazione volta a realizzare il principio della "rimozione degli ostacoli" di cui parla l'articolo 3 della Carta Costituzionale, a prescindere dal quale non si può attuare una concreta uguaglianza tra futuri cittadini. L'accoglienza degli studenti non italofoni è la sfida più importante della scuola di oggi e del futuro. Il presente laboratorio sulle emozioni è stato pensato per aiutare questi alunni, ma anche i loro compagni italiani, a comprendere il proprio disagio. In questo modo, si è cercato di favorire il clima di collaborazione della classe. Il risultato è stato un miglioramento del rendimento scolastico di tutti gli studenti, ma in particolare si è modificata la percezione di sé e dell'altro, favorendo la collaborazione e attenuando il livello di competitività degli studenti.
"Riflessi d'anima nello spirito del fiume". Frammenti di un discorso etico tra l'Io e il Sé in una situazione di coercizione della libertà
Authors: Massa Ope Simona
Published: October 2020

L'articolo è l'elaborazione, dal punto di vista della psicologia analitica, di un'esperienza di espressività corporea condotta dall'Autrice all'interno di una situazione di coercizione della libertà. Il gesto è la parola più antica. Parola intesa non come Logos ma come Mythos: parola simbolica. Il gruppo, tramite il linguaggio del corpo, ha manifestato il mito, la narrazione simbolica, che lo abitava nel qui e ora dell'incontro. È emersa la funzione riparativa dell'inconscio transpersonale rispetto all'assetto della coscienza del gruppo. Il fiume, come immagine archetipica dello spirito, ha rispecchiato valore e purezza originaria a una coscienza identificata con ombre di colpa, vergogna e indegnità.
Psicologia analitica e diritti umani

Published: October 2020

Quali contributi può offrire la psicologia analitica nel riparare gravi violazioni dei diritti umani? La giustizia e l'etica hanno potere curativo? Quali sono gli effetti psicobiologici dell'essere testimoni della sofferenza dell'altro? Che contributo può offrire l'uso simbolico delle immagini nel curare un danno dell'anima? Questi gli spunti di riflessione della tavola rotonda che ha inaugurato l'anno associativo dell'AIPA.

The results will highlight a strong impact of image on some personality traits of the destination and how these personality traits have an effect on the the effective, ideal, social and social ideal destination self congruity and on the intentions of return and word of mouth. The work ends with a discussion on the theoretical and managerial implications in terms of destination branding strategies.
Developing relationships early: How new ventures fill their capability gap
Authors: Di Maria Eleonora , Bettiol Marco , De Marchi Valentina , Grandinetti Roberto
Published: October 2020

In light of the resource-base view of the firm, liability of newness appears as a capability gap. Several studies claim that collaborating with others is an effective strategy for bridging this gap. However, none of them demonstrates that, against a capability gap declared by the new venture at its birth and filled at the end of the start-up phase, this result was achieved by resorting to relations with external actors.The paper aims at answering this research question analyzing both the case of a marketing and technological capability gaps. The empirical section presents the results based on an original dataset on about 400 Italian new ventures. Results show that collaboration with external partners is the only determinant in reducing both capability gaps, whereas the profile of the new venture as well as its size, its location and the founders' education are not relevant. New ventures use external relationships to develop both technological and marketing capabilities.
