Internationalization of family-controlled SMEs from the process, network and socioemotional wealth perspectives
2016
Perheyritysten kansainvälistyminen on saanut vähän huomiota kansainvälisen liiketoiminnan tutkimusalalla. Tämä laadullinen tapaustutkimus tarttuu tähän tutkimusaukkoon ja lähestyy teemaa jopa perheyritysten kansainvälistymistutkimuksessa itsessään suhteellisen vähälle huomiolle jääneiden näkökulmien kautta: prosessi, verkosto ja sosioemotionaalinen vauraus (socioemotional wealth, SEW). Tämä tutkimus tarjoaa vastauksia siihen, kuinka perheiden kontrolloimat pk-yritykset rakentavat kansainvälisiä verkostoja, minkälaisia ulkomaiset verkostosuhteet ovat ja missä määrin SEW selittää yritysten kansainvälistymistä. Jotta tutkimustavoitteilla olisi heijastuspintaa, tutkimusta varten tehtiin kattava…
Accounting in Identity Regulation : Producing the Appropriate Worker
2021
It is acknowledged that identity regulation in organizations relies on discursive resources. This study moves beyond discourse – illustrating how discourse and accounting measurements are mobilized together in revising identity. Measurement produces persistence, clarity, transparency and comparability, as well as direction: Accounting’s quantitative knowledge ‘amplifies’ discourse. We explain the Great Alliance between words and numbers in a case study addressing events in an organization’s transformation. This extends our understanding of what takes place on the interface between identity and accounting. peerReviewed
The role of school physical education on adolescents' fitness levels during the pandemic period from COVID-19: An observational study of the Italian …
2022
ObjectivesIn Italy, in 2013, a new school curriculum with a sport character was established in high schools, called Sports High School (SHS). The aims of this study were: (1) to assess the fitness levels of SHS students who, respecting all the safety rules to limit the spread of COVID-19, practiced physical education (PE) at school with continuity for almost all of 2021, and to compare them with Traditional High School (THS) students; (2) to evaluate as the SHS may have influenced the fitness levels in adolescents.MethodsThis is a case-control study in which thirty participants were enrolled (SHS: n = 15; THS: n = 15). To assess the fitness levels, the following tests were administered: the…
Effects of progressive aquatic resistance training on symptoms and quality of life in women with knee osteoarthritis: A secondary analysis.
2020
Abstract Objective: To conduct a secondary analysis to study the effects, those 4 months of aquatic resistance training have on self‐assessed symptoms and quality of life in post‐menopausal women with mild knee osteoarthritis (OA), after the intervention and after a 12‐month follow‐up period. Methods: A total of 87 post‐menopausal volunteer women, aged 60‐68 years, with mild knee OA were recruited in a randomized, controlled, 4‐month aquatic training trial (RCT) and randomly assigned to an intervention (n = 43) and a control (n = 44) group. The intervention group participated in 48 supervised aquatic resistance training sessions over 4 months while the control group maintained their usual l…
Exercise as stimulus for cartilage health in knee osteoarthritis
2018
Knee osteoarthritis (OA) is a leading cause of musculoskeletal pain and disability and has significant socio-economical costs globally. There is no known cure for OA. Therapeutic exercise has been shown to evoke acute positive posttreatment effects on pain and function. Even though cartilage degeneration is crucial in OA progression, there is sparse knowledge about exercise effects on osteoarthritic cartilage. The purpose of this study was to investigate the efficacy of aquatic resistance training on the estimated biochemical composition of tibiofemoral cartilage and the association between leisure time physical activity (LTPA) and tibiofemoral cartilage in postmenopausal women with mild kn…
Cilvēka 14. hromosomas proteasomu gēnu polimorfismu asociāciju ar multiplo sklerozi izpēte Latvijas populācijā
2018
Proteasomālo gēnu polimorfismi ir autoimūnu slimību riska faktori. Lai novērtētu potenciālus multiplās sklerozes (MS) biomarķierus Latvijas populācijā, veicām proteasomālo gēnu PSMA6 un PSMC6 polimorfismu genotipēšanu 280 pacientiem ar MS diagnozi, ko salīdzinājām ar iepriekš ievāktiem datiem no 305 kontrolēm ar mērķi izpētīt iespējamo asociāciju starp šo lokusu polimorfismiem un MS. Tālākā analīzē kombinācijā ar iepriekšējiem PSMA3 polimorfismu genotipēšanas datiem atradām divus klīniski nozīmīgus multi-lokusu genotipus un trīs klīniski nozīmīgus haplotipus. Daļai pētīto polimorfismu novērojām no alēlēm atkarīgas alternatīvas DNS sekundārās struktūras. PSMA6 rs1048990 polimorfisma minorajā…
Influenza delle infrastrutture ecologiche poste ai margini del vigneto su Empoasca vitis (Goethe) (Homoptera: Cicadellidae) e il suo parassitoide Ana…
2014
È ormai opinione diffusa che la diversità vegetale all’interno degli agrosistemi favorisca il mantenimento dell’entomofauna utile ai fini di un contenimento naturale di fitofagi. In quest’ambito, il presente lavoro ha riguardato uno studio, sulle popolazioni di Empoasca vitis e del suo parassitoide Anagrus atomus in un’azienda viticola sita nel comprensorio di Salemi (TP) (446 m s.l.m.) a conduzione biologica prendendo in considerazione due appezzamenti, uno con ai margini siepi di rovo, rosa canina e rosmarino e l’altro in assenza di siepi. Nel periodo vegeto-produttivo della vite (marzo-ottobre 2012), si è valutata l’influenza della specie vegetale e della variazione della distanza delle …
Damping Provision by Different Virtual Synchronous Machine Schemes
2020
The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…
Sensitivity Analysis and Frequency Dynamics of Grid-Connected Converters with Virtual Inertia
2021
For the participation in the frequency control of the system, power converters can be controlled with different strategies and methods, sharing the common concept of virtual inertia capability. In this work, a sensitivity analysis of two main categories of converter controls with virtual inertia is presented. The considered schemes are a grid-following current vector control with additional virtual inertia block and a grid-forming control scheme based on virtual synchronous machine concept. A proper basis for the comparison is first assessed providing an analytical correlation between the control parameters of the two schemes. For the two control strategies, the sensitivity analysis of the …
Enhancement of hepatitis C virus RNA replication by cell culture-adaptive mutations.
2001
ABSTRACT Studies of the Hepatitis C virus (HCV) replication cycle have been made possible with the development of subgenomic selectable RNAs that replicate autonomously in cultured cells. In these replicons the region encoding the HCV structural proteins was replaced by the neomycin phosphotransferase gene, allowing the selection of transfected cells that support high-level replication of these RNAs. Subsequent analyses revealed that, within selected cells, HCV RNAs had acquired adaptive mutations that increased the efficiency of colony formation by an unknown mechanism. Using a panel of replicons that differed in their degrees of cell culture adaptation, in this study we show that adaptive…
