Slack organizzativo e Shadow options. L'influenza della path dependency sulle potenzialità di sviluppo dell'impresa
No full textIn un contesto caratterizzato da livelli crescenti di incertezza e dinamicità ambientale, la flessibilità strategica acquisisce sempre maggior valore, misurabile mediante il ricorso a metodi quali le opzioni reali. In particolare, il Real Options Reasoning consente di rappresentare qualitativamente le potenziali traiettorie di sviluppo dell'impresa e la concatenazione delle opzioni reali, secondo un approccio path dependent. In particolare, nel volume si analizza il ruolo dello slack di risorse come serbatoio di potenziali opportunità di sviluppo e come driver di shadow options, opzioni latenti, non ancora riconosciute dal management, suscettibili di trasformarsi in strategic growth options

Implant survival after sinus elevation with Straumann(®) BoneCeramic in clinical practice: ad-interim results of a prospective study at a 15-month follow-up.
No full textAbstract: Objectives
Elevation of the sinus floor with Straumann (R) BoneCeramic gave promising results in some recent clinical studies. However, no study has evaluated the long-term survival of implants after this surgical procedure. We are conducting a prospective, observational study to evaluate the long-term implant survival after this surgical procedure in clinical practice. We present here an ad-interim report of this study, including only patients with >= 12-month follow-up after implant placement.
Methods
This prospective cohort study will last until a follow-up of 5 years will be achieved in at least 50 patients. Inclusion criteria are: age >= 18 years; presence of a maxillary partial unilateral or bilateral edentulism involving the premolar/molar areas; elective rehabilitation with oral implants; and physical capability to tolerate conventional surgical and restorative procedures. Patients are treated according to the two-stage technique and the preparation is filled with Straumann (R) BoneCeramic. Implant survival is evaluated every 3 months for the first 2 years, and then every 6 months up to 5 years.
Results
Fifteen patients are considered in this ad-interim analysis. Mean follow-up was 14.9 +/- 3.1 (range: 6-18 months). In total, three implants failed, in one single patient, 6 months after insertion. The cumulative implant survival rate was 92.5% (95% confidence interval: 83.0-100%).
Conclusions
This ad-interim analysis suggests that the elevation of the sinus floor with Straumann (R) BoneCeramic may be an effective clinical option over > 1-year follow-up. A longer term follow-up will allow a deeper characterization of these preliminary findings

Characteristics of social entrepreneur: an explorative analysis
No full textObjectives. This study focuses on social ventures as for-profit organizations which bases their survival on social
legitimacy and generates a social value, by employing usually marginalized categories of individuals. Specifically,
this paper study main characteristics of starting a business in case entrepreneurs hails from a disadvantaged group
of people.
Methodology. We use a an extremely large-scale sample, at worldwide level, including 1563 observations. The time
span covers the period 2004-2018. We investigates main characteristics of starting a business considering census
(low and low-medium income) of the founder and gender. We perform one-way Anova and correlation statistics.
Findings. Our results confirms that, despite policy makers efforts, underdog individuals still have poor
possibilities of starting a business because of capital required. Difficulties are greater for womenthan for men.
Research limits. The main limits of the analysis are the small number of variables used to investigate social
ventures and the explorative method, which does not allow to detect causal relationships.
Practical implications. At a macro-level, the paper shows that policies for incentivizing social entrepreneurship
and social development are still scarcely effective.
Originality of the study. This contribution extends the knowledge in a field of research which is rather new. We
originally contribute by digging to light that differences in gender are a poor explanation for social
entrepreneurship. Findings are largely reliable because the massive number and time-coverage of observations.
Routinely collected observations are deemed to be less biased than cross-sectional analysis.
Thus, the study detects a salient path in social entrepreneurship
Open Innovation: A Systematic Literature Analysis
No full textWhat is open innovation? There are different definitions of open innovation, depending, at least,
on three parameters: source; ownership; or users of the knowledge linked to innovation. The aim
of the paper is to make a systematic literature review, to map open innovation studies, and to reconceptualize
the openness according to two dimensions: degree of technology convergence and
ontology of openness. In particular, we propose a classification of open innovation, based on the
distinction between the originator/developer of the knowledge and the user. Users are an
ubiquitous category, because they can be originators, as well as customers of the innovation itself.
Therefore, we point out that there are three types of open innovation, which degree of openness is
defined according an ontological dimension: at users' level; at an industry level; and among
different fields or industries. Firm’s structure affects the propensity to open innovation adoption;
and the type of innovation itself. Finally, we identify another literature gap: the relationship
between the open innovation model and Grand Challenge. Even if open innovation seems to be
ideally connected to Grand Challenges and many industries actually adopt this model, there
seems to emerge a gap in literature. Therefore, we propose a conceptual model for future
researches
