Carsharing business models in Germany: characteristics, success and future prospects
2017
Carsharing provides an alternative to private car ownership by allowing car use temporarily on an on-demand basis. Operators provide carsharing services using different business models and ownership structures. We distinguish between cooperative, business-to-consumer (B2C) roundtrip and one-way, as well as peer-topeer (P2P) carsharing. This paper characterizes these different types of business models and compares their success in terms of diffusion using a comprehensive database of all 101 German carsharing providers in 2016. The key result holds that fleet size is significantly different across business models ranging from a few cars (cooperatives in small towns), to a few hundred (B2C rou…
Effectuation Logic in Digital Business Model Transformation : Insights from Japanese High-Tech Innovators
2019
Purpose The purpose of this paper is to study how digital business models evolve when entrepreneurs move to new digital platforms and how this evolution is related to effectuation and causation logics. Design/methodology/approach This study applies a multiple case study approach to investigate how digital business models change in small, Japanese high-tech firms providing their innovations through different digital platforms. To investigate digital business models, this study considers the elements that comprise general business models. The case firms were selected based on size, products and transitions from physical to various digital platforms. Semi-structured interviews were conducted …
The Design Towards a Collaborative Subscription Service : The Case of The Finnish Newspaper Industry
2020
The newspaper industry is challenged with its business models. To stabilize revenues, publishers opted for digital subscriptions for generating additional revenue streams. However, digital subscriptions showcase limited success. News aggregator platforms may promise publishers a pool of paying readers. But platform fees and the loss of customer relationships enact barriers among publishers to join. This study proposes a software prototype based on design science research to address the aforementioned shortcomings by deriving design principles for a collaborative subscription service. Building on the strategic alliance, digital platform and business model literature, this research aims to id…
Latvijas iedzīvotāju subjektīvā labklājība un tās neseno izmaiņu analīze
2020
Katru gadu valsts politikas izstrādē un budžeta līdzekļu pārdalē ir aktuāls jautājums par prioritātēm. Ja valsts politikas stratēģiskais mērķis ir laimīgāki Latvijas iedzīvotāji, tad ir nepieciešams saprast, kādi faktori ietekmē Latvijas iedzīvotāja laimi jeb subjektīvo labklājību, lai pēc iespējas efektīvāk izlietotu budžeta līdzekļus. Balstoties uz Eiropas Savienības Ienākumu un dzīves apstākļu 2013. un 2018. gada apsekojuma rezultātiem par Latvijas iedzīvotājiem, un izmantojot lineārās regresijas mazāko kvadrātu metodi un Stata datorprogrammu, pētījumā tiek identificēti galvenie Latvijas iedzīvotāju laimes (subjektīvās labklājības) faktori. Šie faktori ir veselības stāvoklis, ienākumi un…
Mazo RNS raksturošana ārpusšūnas vezikulās, kas iegūtas no prostatas vēža pacientu urīna un plazmas paraugiem
2017
Ārpusšūnas vezikulas (EVs) nodrošina starpšūnu komunikāciju fizioloģiskos procesos un dažādās saslimšanās, ieskaitot ļaundabīgos audzējus. EV RNS satura izpēte dotu iespēju atklāt jaunus prostatas vēža (PCa) biomarķierus. Šis darbs tiek fokusēts uz mazo RNS raksturošanu, kas iegūtas no PCa pacientu plazmas un urīna EVs, kā arī no PCa un normāliem prostatas audiem, izmantojot RNS sekvencēšanu. Rezultāti uzrādīja, ka gan plazmas, gan urīna EVs satur matrices RNS fragmentus, mikro RNS, garās-nekodējošās RNS, piwi-saistošās RNS un citas nekodējošās RNS, taču to proporcijas ievērojami variē starp indivīdiem. Daļa šo RNS ir paaugstināti ekspresētas vēža audos un varētu būt piemērotas kā PCa bioma…
Iniuria Migrandi: Criminalization of Immigrants and the Basic Principles of the Criminal Law
2013
In questo articolo mi propongo di effettuare una valutazione normativa, dal punto di vista di una teoria del diritto penale orientata secondo principi, delle norme che incriminano l'immigrazione irregolare. L'interrogativo generale sul quale mi soffermerò è questo: che modo di usare il diritto penale è implicato nella emanazione di simili norme? La mia tesi è, in sintesi, che si tratta di un vero e proprio abuso del diritto penale. In almeno due sensi: primo, nel senso che, criminalizzando l'immigrazione irregolare, il diritto penale bandisce (categorie di) persone, e non atti/omissioni, facendo qualcosa che un diritto penale rispettoso di alcuni principi liberali fondamentali non dovrebbe …
Data from: Long live the alien: is high genetic diversity a pivotal aspect of crested porcupine (Hystrix cristata) long-lasting and successful invasi…
2016
Studying the evolutionary dynamics of an alien species surviving and continuing to expand after several generations can provide fundamental information on the relevant features of clearly successful invasions. Here, we tackle this task by investigating the dynamics of the genetic diversity in invasive crested porcupine (Hystrix cristata) populations, introduced to Italy about 1500 years ago, which are still growing in size, distribution range and ecological niche. Using genome-wide RAD markers, we describe the structure of the genetic diversity and the demographic dynamics of the H. cristata invasive populations and compare their genetic diversity with that of native African populations of …
Quality Analysis of YouTube Videos Presenting Pelvic Floor Exercises after Prostatectomy Surgery
2021
Background: Prostate cancer (PC) is a major cause of disease and mortality among men. Surgical treatment involving the removal of the prostate may result in temporary or permanent erectile dysfunction (ED) and urinary incontinence (UI), with considerable impact on quality of life. Pelvic floor muscle training (PFMT) is one of the recommended techniques for the prevention, treatment, and rehabilitation of postoperative complications. The aim of this observational study was to assess the quality of YouTube videos—accessible to any patient—related to exercises after prostatectomy surgery. Methods: A systematic search was performed on YouTube on 24 September 2020. One hundred and fifty videos w…
Towards clinical application of RayStretch for heterogeneity corrections in LDR permanent 125-I prostate brachytherapy
2017
Purpose RayStretch is a simple algorithm proposed for heterogeneity corrections in low-dose–rate brachytherapy. It is built on top of TG-43 consensus data, and it has been validated with Monte Carlo (MC) simulations. In this study, we take a real clinical prostate implant with 71 125I seeds as reference and we apply RayStretch to analyze its performance in worst-case scenarios. Methods and Materials To do so, we design two cases where large calcifications are located in the prostate lobules. RayStretch resilience under various calcification density values is also explored. Comparisons against MC calculations are performed. Results Dose–volume histogram–related parameters like prostate D90, …
Le carriere universitarie degli studenti negli atenei statali e non statali in Italia
2020
Negli ultimi anni si è assistito ad un incremento della competizione tra gli atenei per “accaparrarsi” gli studenti, a cui si aggiunge una sempre maggiore attività di promozione e di reclutamento degli studenti delle università non statali (telematiche e non). Le università non statali, altrimenti denominate “libere Università”, sono promosse sia da enti di diritto privato che da enti pubblici (regioni, province, comuni). Esse sono legalmente riconosciute dal Ministero dell'Istruzione dell'Università e della Ricerca, e autorizzate a rilasciare titoli accademici, relativi all’ordinamento universitario, di valore legale identico a quelli rilasciati dalle università statali. La letteratura ha …
