Evaluation of the RYR1 gene genetic diversity in the Latvian White pig breed
2016
The ryanodine receptor 1 (RYR1) is a calcium ion channel in the sarcoplasmic reticulum of skeletal muscle. Multiple polymorphic loci have been identified in the RYR1 gene in human and animals and some of them are associated with certain phenotypes. However, there are still few data on the RYR1 genetic variability in pig and only the missense mutation Arg615Cys, associated with the malignant hyperthermia, porcine stress syndrome and meat quality, has been studied in several commercial and local breeds. Aim. To genotype the rs344435545 (C1972T, Arg615Cys), rs196953058 (T8434C, Phe2769Leu) and rs323041392 (G12484A, Asp4119Asn) in the Latvian local pig breed Latvian White and to evaluate the ev…
Lean Internal Startups for Software Product Innovation in Large Companies: Enablers and Inhibitors
2018
Context: Startups are disrupting traditional markets and replacing well-established actors with their innovative products.To compete in this age of disruption, large and established companies cannot rely on traditional ways of advancement, which focus on cost efficiency, lead time reduction and quality improvement. Corporate management is now looking for possibilities to innovate like startups. Along with it, the awareness and the use of the Lean startup approach have grown rapidly amongst the software startup community and large companies in recent years. Objective: The aim of this study is to investigate how Lean internal startup facilitates software product innovation in large companies.…
Sosiaalisen median hyödyntäminen suomalaisissa yksityisen sektorin suuryrityksissä
2014
Työssä tutkittiin suomalaisen yksityisen sektorin suuryritysten suhtautumista sosiaaliseen mediaan ja sosiaalisen median hyödyntämistä. Suhtautumisesta tutkittiin, millaista se on ja miten se on muuttunut viime vuosina. Hyödyntämisestä tutkittiin, millaisia käyttötarkoituksia organisaatioilla on eri sosiaalisen median palveluille, millaisia tavoitteita käytölle on asetettu ja millaisia sääntöjä, ohjeita tai rajoituksiao rganisaatioissa on sosiaalisen median käytölle. Tutkimus toteutettiin laadullisia menetelmiä ja sisällönanalyysejä hyödyntäen. Tutkimusmenetelmänä oli avoin teemahaastattelu ja aineisto hankittiin haastattelemalla kuutta yksityisen sektorin suuren organisaation tiedonantajaa…

Non-IFRS and changes in accounting institutions : Lessons from Nokia
2022
We analyse the lessons learned from Nokia to illustrate the changing focus in accounting and organisational practices that affect the perceptions of relevant accounting work and the key measures of success. In the course of an analysis covering 25 years, the introduction of management accounting innovations was first emphasised regarding managerial relevance but were later replaced by financial accounting emphasis and innovations (e.g. non-IFRS reporting). Our data includes public reports, newspaper articles and 21 interviews made between 1996 and 2019. We present a framework for analysing shifts in the focus of accounting. Our case analysis on changing accounting practices, on shifting pe…
Impaired Binding to Junctophilin-2 and Nanostructural Alteration in CPVT Mutation
2021
Rationale: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare disease, manifested by syncope or sudden death in children or young adults under stress conditions. Mutations in the Ca 2+ release channel/RyR2 (type 2 ryanodine receptor) gene account for about 60% of the identified mutations. Recently, we found and described a mutation in RyR2 N-terminal domain, RyR2 R420Q . Objective: To determine the arrhythmogenic mechanisms of this mutation. Methods and Results: Ventricular tachycardias under stress conditions were observed in both patients with catecholaminergic polymorphic ventricular tachycardia and knock-in mice. During action potential recording (by patch-clamp in …

Institutional systems inducing R&D in Amazon- the role of an investor surplus toward stakeholder capitalization
2020
Abstract Amazon demonstrated a conspicuous increase in R&D and became the world's top R&D firm in 2017 with a skyrocketing increase in market capitalization, making it close to being the world's biggest company. Such a remarkable accomplishment can be attributed to Amazon's institutional systems, which orchestrate techno-financing systems that fuse a unique R&D transformation system and a sophisticated financing system centered on the cash conversion cycle (CCC). These institutional systems support and endorse aggressive investment in R&D that incorporates the characteristics of uncertainty, a long lead time, and successive inflows of very large amounts of funding without interruption. Whil…
Redox signaling in acute pancreatitis
2015
Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On th…
The role of negative and positive forms of power in supporting CSR alignment and commitment between large firms and SMEs
2018
Do large firms exert power to shape the CSR behavior of their SME partners?” We answer this question by proposing a model built on the stakeholder theory and the shareholder theory, and go on to explain how this impact influences the commitment of the SME towards their large partner. The model highlights the central role that different forms of power exercised by the large firm play in the process. A survey of 291 SMEs confirms the key hypotheses, including the mediating role of reward power. The effects of coercive power are noteworthy and they illustrate the complex and competing forces at play in influencing CSR behavioral change in SMEs. The research makes a novel contribution to practi…
