Alliance formation as growth opportunity for non-publicly traded companies: a value-added service provided by private equity investors
2016
We analyze the role of Private Equity firms (PE-Firms) as a governance mechanism, focusing on their role as social intermediaries, helping their portfolio companies to form alliances and thereby spurring entrepreneurial growth. Alliances as long term inter-firm cooperations are considered to be a main source of firm-innovation. External growth via alliances is especially important for small to medium sized companies (SME) – largely dominant in Europe (up to 99%)–, because their internal resources are limited. Since a few years, these facts lead governments to undertake actions aimed to create environments that boost inter-firm linkages and entrepreneurial clusters. In European countries, su…
Enhancing policy design and sustainable community outcomes through collaborative platforms based on a dynamic performance management and governance a…
2022
This chapter aims at illustrating how a Dynamic Performance Management and Governance approach may support the implementation of “collaborative platforms” (Ansell and Gash, 2018) to enhance network policy design and the pursuit of sustainable community outcomes. This is an emerging field of research, embracing performance management, collaborative governance, and systems theory, aimed at fostering a learning-oriented perspective in performance data use. Such a view has been also referred as “collaborative performance management”, i.e., the “sharing of resources and information among different actors for the purposes of achieving a formal performance goal” (Choi and Moynihan, 2019, p. 1539).…
A Gravitational-wave Measurement of the Hubble Constant Following the Second Observing Run of Advanced LIGO and Virgo
2021
This paper presents the gravitational-wave measurement of the Hubble constant (H 0) using the detections from the first and second observing runs of the Advanced LIGO and Virgo detector network. The presence of the transient electromagnetic counterpart of the binary neutron star GW170817 led to the first standard-siren measurement of H 0. Here we additionally use binary black hole detections in conjunction with galaxy catalogs and report a joint measurement. Our updated measurement is H 0 = km s-1 Mpc-1 (68.3% of the highest density posterior interval with a flat-in-log prior) which is an improvement by a factor of 1.04 (about 4%) over the GW170817-only value of km s-1 Mpc-1. A significant …
Gravitational-wave Constraints on the Equatorial Ellipticity of Millisecond Pulsars
2020
We present a search for continuous gravitational waves from five radio pulsars, comprising three recycled pulsars (PSR J0437-4715, PSR J0711-6830, and PSR J0737-3039A) and two young pulsars: the Crab pulsar (J0534+2200) and the Vela pulsar (J0835-4510). We use data from the third observing run of Advanced LIGO and Virgo combined with data from their first and second observing runs. For the first time, we are able to match (for PSR J0437-4715) or surpass (for PSR J0711-6830) the indirect limits on gravitational-wave emission from recycled pulsars inferred from their observed spin-downs, and constrain their equatorial ellipticities to be less than 10-8. For each of the five pulsars, we perfor…
Exploring travelers’ willingness to pay for green hotels in the digital era
2021
The past few years have witnessed an intensifying effort by hotels to respond to customers’ growing environmental sensitivities. A critical aspect of this market trend is the actual willingness of tourists to pay (WTP) for green products and services offered by green hotels. Previous studies in this research field have mainly focused on the relationship between guests’ attitudes and their behavioral intentions, neglecting the influence of external and situational factors. In light of this, the present paper contributes to knowledge by analyzing the influence of e-Word-of-Mouth (e-WOM) and physical image, as it emerges from digital platforms, and the effect of green hotel attributes on the t…
Combining Value and Momentum: Evidence from the Nordic Equity Market
2018
This is the first paper that explores Fisher, Shah and Titman’s (2016) average ranking approach for the value and momentum strategy in the Nordic equity market offering an exceptional experimental environment. Our results indicate that in the Nordic stock markets, the value anomaly offered excess returns in the 1993 to 2017 sample period only when small stocks were a part of the portfolio, whereas the momentum effect is strong and significant, irrespective of size. Interestingly, our findings also indicate that the negative correlation between value and momentum (Asness, Moskowitz and Pedersen, 2013) seems to be driven by growth stocks: Winner stocks that are value stocks generated 1.66% pe…
Kirja-arvostelut alustataloudessa – esimerkkinä käyttäjälähtöiset arvostelut Instagramissa
2021
Kulttuurituotteita eivät sosiaalisen median aikakaudella enää arvostele julkisesti vain perinteisen median ammattikriitikot, vaan myös tavalliset ihmiset osallistuvat teosten julkiseen arvottamiseen erilaisilla digitaalisilla alustoilla. Tarkastelemme tässä artikkelissa kirjallisuusarvosteluja osana alustoitunutta kulttuurituotantoa esimerkkinämme käyttäjälähtöiset kirja-arvostelut erityisesti kuvasovellus Instagramissa. Instagramiin on vakiintunut kirjallisuuskeskusteluyhteisö, jota kutsutaan maailmanlaajuisesti nimellä Bookstagram mutta jolla on myös paikallisia tai alueellisia muotoja, kuten suomalainen Kirjagram. Kysymme, miten käyttäjäarvostelijat esiintyvät niissä arvostelulle määrite…

Human milk is not “merely nutritious”: How its bioactive role can influence child health
2021
Maternal milk represents the best food for the newborn, providing specific physiologic advantages over the other sources of nutrition. It also contains many hundreds to thousands of bioactive molecules that protect against infection (i.e. IgA), inflammation (i.e. 5-methylthioadenosine) and contribute to eliciting strong immune responses in breastfed children (i.e. allergens or viral antigens). Quality and quantity of breast milk components may influence the development of infant body composition in the first years of life; in particular, it has been shown that a different composition of human oligosaccharides (HMOs) in overweight/obese women’s human milk can be correlated with her offspring…
