Supporting Multi-Sided Platform firms to maintain rapid growth (and to avoid failure) over time through a Dynamic Business Modelling approach

2020

Over the last few decades, the diffusion of the sharing economy has nurtured continuous changes in business model opportunities with multi-sided platforms (MSPs) in many industries. MSPs are digital exchange platforms aiming at connecting unmatched demand- and supply- side participants through the use of internet technology. In many cases, such start-up initiatives have led to the creation of scale-up or high-growth firms (HGFs). However, in spite of the significant contribution to both economic development and employment, current studies seem to investigate primarily in an isolated perspective HGFs, MSPs and their business model innovation (BMI). The existing literature on HGFs focuses on …

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

The challenge for economics from the new 'digital' economy: sharing and collaborative economy through the 'platforms neocapitalism' of the 21st centu…

2021

The so-called collaborative or sharing economy constitutes a multifaceted concept of increasing relevance and evolving in definition that will constitute the focus of our study. This article is presented methodologically as a macro-synthesis of the main trends of the economy, from its local and global spheres, in the convergence that can be glimpsed from the new phenomenon that we are dealing with of neo-capitalism based essentially on digital platforms and media. Some have already advanced it as turbo-capitalism or capitalism 3.0, in increasing expansion from the analysis of massive data from digital platforms. The resulting greater efficiency of decentralization and heterogeneity can be e…

The Power of Word-Frequency Based Alignment-Free Functions: a Comprehensive Large-Scale Experimental Analysis

2021

Abstract Motivation Alignment-free (AF) distance/similarity functions are a key tool for sequence analysis. Experimental studies on real datasets abound and, to some extent, there are also studies regarding their control of false positive rate (Type I error). However, assessment of their power, i.e. their ability to identify true similarity, has been limited to some members of the D2 family. The corresponding experimental studies have concentrated on short sequences, a scenario no longer adequate for current applications, where sequence lengths may vary considerably. Such a State of the Art is methodologically problematic, since information regarding a key feature such as power is either mi…

Value Creation and Power Asymmetries in Digital Ecosystems : A Study of a Cloud Gaming Provider

2020

Digital platforms connecting users and service providers have a central role in determining the value creation structure of ecosystems. Platform developers try to achieve a dominant position for the platform with a strong ecosystem around it. The size and attractiveness of the services can attract new users, and growing user volume can bring new co-operative service providers to the service partner network. An interesting question is how the presence of power and potential power asymmetry affect the value creation capability and the structure of a network around a platform? This chapter describes an example of value creation and the influence of power asymmetry in a digital ecosystem built …

3D high definition video coding on a GPU-based heterogeneous system

2013

H.264/MVC is a standard for supporting the sensation of 3D, based on coding from 2 (stereo) to N views. H.264/MVC adopts many coding options inherited from single view H.264/AVC, and thus its complexity is even higher, mainly because the number of processing views is higher. In this manuscript, we aim at an efficient parallelization of the most computationally intensive video encoding module for stereo sequences. In particular, inter prediction and its collaborative execution on a heterogeneous platform. The proposal is based on an efficient dynamic load balancing algorithm and on breaking encoding dependencies. Experimental results demonstrate the proposed algorithm's ability to reduce the…

Il lavoro etero-organizzato prima e dopo il caso Foodora Italia.

2019

l contributo ripropone la discussione sull’esegesi della fattispecie disciplinata dall’art. 1 comma 2 del d. lgs. n. 81 del 2015 (nel testo anteriore alla riforma del 2019) trattata dall’autore nei Colloqui Giuridici sul Lavoro del 2015 (a cura) di Antonio Vallebona per il Massimario di Giurisprudenza del Lavoro. Lo studio rigettava la tesi che il lavoro organizzato dal committente fosse la terza fattispecie e anzi con riferimento delle condizioni di applicazio­ne dimostrava la necessità di una lettura includente. La conclusione era che la nuova disciplina aveva natura antifraudolenta e determinava un allargamento (relativo) dell’area della subordi­nazione conseguente alla riduzione del cam…

This article republishes (after the Italian Supreme Court judgement n.166/2020 on the Foodora Italia case) the contribution to the exegesis of the case brought by art. 1 para­graph 2 of the d. lgs. n. 81 of 2015 (in the text before the 2019 reform) delivered by the author in the 2015's "Colloqui Giuridici sul Lavoro" (edited) by Antonio Vallebona for the "Massimario di Giurisprudenza del Lavoro". The study rejected the thesis that the job organ­ised by the client was an intermediate regulation between the employee and the self-employed ones. Indeed regarding the conditions for its application it showed the need for extensive reading. The conclusion was that the new discipline was (and is) an anti-fraudulent one. It led to a (relative) expansion of the area ofsubordination as a consequence of a reduction in the scope of coordinated self-employed work. A little more than four years after that article the Italian Supreme Court (with the judgement n.166/2020) on the Foodora Italia case addresses for the first time the issue of the hetero-organised work (by art. 1 paragraph 2 of the d. lgs. n. 81 of 2015). The Supreme Court fully adheres to the paper's thesis. So in terms of the "re­medial" function of the standardthe nature of the organisation's specific conditionand eventually reducing the legal frame for coordinated work. The fact that the procedural matter dealt with the riders was (then and now is) utterly irrelevant for the correct interpretation of such a new provision. Giving to riders of the employee status is not an effect of the peculiarit­ies of the work through digital platforms. It is a consequence of the remedial nature of such a case-law.

On the conversation between female videobloggers and commentators

2021

El desarrollo de YouTube como una plataforma social surge a partir de dos ideas. En primer lugar, los amateurs pueden producir contenido de cualquier índole. Y, en segundo lugar, su audiencia puede expresar su opinión sin restricciones. Este intercambio de información impulsa la formación de comunidades en torno a un interés común: contenido y/o videobloguero. La dimensión social en YouTube tiene lugar de manera bidireccional. La interacción regular entre las dos partes ha significado un cambio crucial en la percepción de la producción y consumo audiovisual, así como también en los productores de vídeo, amateurs y audiencia. Las investigaciones iniciales se han dirigido a examinar los comen…

Laika-aspekta formu lietojums filmu recenzijās

2020

Recenzijas ir žanrs filmu producēšanas jomā un liels skaits recenziju katrai jaunajai filmai ir atrodams vairākos medijos un tiešsaistes platformās. Ir tikuši veikti pētījumi par stilistiskajiem aspektiem, kas veido filmu recenzijas interneta laikmetā. Gramatisko pētījumu trūkums filmu recenzijās veicina turpmākus pētījumus šajā jomā. Tādēļ, šī pētījuma mērķis ir pētīt laika-aspekta formu biežumu un pielietojumu tiešsaistes filmu recenzijās. Lai sasniegtu mērķi, tika izmantotas divas pētnieciskās metodes biežuma analīze un diskursa analīze. Analīzes apkopotie dati atklāja, ka visbiežāk izmantotās laika-aspekta formas tiešsaistes filmu recenzijās bija vienkāršā tagadne un vienkāršā pagātne, …

Key factors of information management for crowdfunding investor satisfaction

2021

Abstract Crowdlending platforms are becoming increasingly important as a collective financing mechanism for entrepreneurs and small and medium-sized enterprises (SMEs), especially those at an early stage. This study, which is based on a survey of investors on a Spanish crowdlending platform, uses fuzzy-set qualitative comparative analysis (fsQCA) to examine investor satisfaction with crowdlending platforms. Specifically, the study examines communication policies and the quality of the investor experience based on the information provided by these platforms. The value of this article lies in its examination of the antecedents of crowdlending investor satisfaction. The analysis shows that the…
