Three-dimensional bimetallic octacyanidometalates $[M^{IV}{(\mu-CN)_{4}Mn^{II}(H_{2}O)_2}_2 \cdot 4H_{2}O]_{n}$ (M=Nb,Mo,W) : synthesis, single-cryst…
2008
Abstract We report the synthesis, the single-crystal X-ray crystallographic structures and the magnetic properties of three new isostructural cyanido-bridged networks: [M IV {(μ-CN) 4 Mn II (H 2 O) 2 } 2 ·4H 2 O] n [M IV = Nb IV ( 1 ), Mo IV ( 2 ), W IV ( 3 )]. For compound 1 , the magnetic properties reveal a ferrimagnetic phase below 50 K. In contrast, compounds 2 and 3 show a paramagnetic behaviour with no magnetic ordering down to 2 K. The only electronic difference between the two kinds of compounds is the presence of two paired electrons on Mo IV ( 2 ) and W IV ( 3 ) (d 2 electronic configuration, S = 0) with no possible exchange interactions with Mn II ions (d 5 electronic configur…
Networking Strategies as Enabler for Competitive Advantage Creation: market-based and resource-based Perspectives
2010
This paper explores the potential of networking strategy as a source of competitive advantage by integrating market-based and resource-based logics. It contributes to production economics literature by considering not just supply chain network structures but also others kinds of network that can emerge from horizontal agreements (i.e. alliances, partnerships, joint ventures, consortia, etc.). The paper reviews the literature and develops propositions regarding how make/buy/make together decisions, governance mechanisms and network-base structures allow firms both to pursue pre fixed operations performance objectives and obtain/create valuable resources. The practical applications of the pro…
Banku saistību līmeņa samazināšanās procesa ietekme uz Latvijas tautsaimniecību
2015
2008. gada globālā ekonomiskā krīze vēlreiz apliecināja finanšu sistēmas ciešo saistību ar reālo ekonomiku, tāpēc tiek izstrādāti Basel III banku regulējošie nosacījumi, kuri paredz bankām uzturēt zemāku saistību līmeni, kas savukārt ietekmēs valstu tautsaimniecības. Bakalaura darba mērķis ir analizēt Latvijas komercbanku saistību līmeņa samazināšanās ietekmi uz Latvijas tautsaimniecību, lai raksturotu Basel III regulu iespējamo makroekonomisko ietekmi un izvirzītu priekšlikumus attiecīgajām institūcijām ar nolūku uzlabot makroprudenciālo uzraudzības politiku, kā arī lai izvirzīt priekšlikumus tālākai temata pētniecībai. Banku saistības tiek novērtētas izmantojot Basel III regulējošo nosacī…
Convolutional Neural Network Based Sleep Stage Classification with Class Imbalance
2022
Accurate sleep stage classification is vital to assess sleep quality and diagnose sleep disorders. Numerous deep learning based models have been designed for accomplishing this labor automatically. However, the class imbalance problem existing in polysomnography (PSG) datasets has been barely investigated in previous studies, which is one of the most challenging obstacles for the real-world sleep staging application. To address this issue, this paper proposes novel methods with signal-driven and image-driven ways of noise addition to balance the imbalanced relationship in the training dataset samples. We evaluate the effectiveness of the proposed methods which are integrated into a convolut…
Supported Web-Based Acceptance and Commitment Therapy for Older Family Caregivers (CareACT) Compared to Usual Care
2021
Objectives: The objective of the present study was to investigate whether an acceptance and commitment therapy (ACT)-based web-intervention (Group 1, CareACT), or a standardized rehabilitation in a rehabilitation center (Group 2) was effective in enhancing the psychological well-being of family caregivers aged 60 and over compared to support provided by voluntary caregiver associations (Group 3). Methods: Altogether, 149 family caregivers participated in this quasi-experimental study. Primary outcome measure was depression. Secondary outcomes included anxiety, sense of coherence, quality of life, psychological flexibility, experiential avoidance, and thought suppression. The questionnaires …
CareACT - internet-based intervention for enhancing the psychological well-being of elderly caregivers – a study protocol of a controlled trial
2019
Abstract Background The rapid increase in the number of elderly family caregivers underlines the need for new support systems. Internet-delivered psychological interventions are a potential approach, as they are easy to access for family caregivers who are often homebound with their care recipient. This study examines the relative effectiveness of an internet-based acceptance and commitment therapy (ACT) intervention or a standardized institutional rehabilitation program, first, in reducing depressive symptoms, and second, in improving the well-being and quality of life of elderly family caregivers compared to a control group receiving support from voluntary family caregiver associations. M…
Flow with Nature treatment for depression: Participants’ experiences
2022
This study examined Flow with Nature (FWN) treatment, which is an integrative intervention (rehabilitation) based on eco and environmental psychology, psychotherapeutic theories and professional psychological practice. FWN is intended for depression rehabilitation with the help of social support, nature environments and FWN exercises. Exercises encourage sensing the environment, mindful awareness, psychological processing and focusing on the future. The FWN treatment proceeds in separate stages (horizon, growth and path), which emphasise nature, group (social support) and FWN exercises differently. This study focused on the experiences of the participants in the FWN treatment. Finnish adult…
Monitoring a meat-free pledge with smartphones:An experimental study
2020
Pledges are a popular strategy to encourage meat reduction, though experimental studies of their efficacy are lacking. Three-hundred and twenty-five participants from three different countries (UK, Germany, Australia) were randomly assigned to pledge 28 days meat-free or not, and their behavior was tracked via smartphones. Participants answered daily surveys regarding their eating behavior, meat cravings, and shared photos of their meals. Baseline data was collected prior to the pledge, after the 28 days, and one-month post-intervention. Participants assigned to the pledge condition ate less meat across the 28 days, compared to control participants. Meat reductions, observed at outtake, did…
Expression and characterization of the recombinant juvenile hormone epoxide hydrolase (JHEH) from Manduca sexta.
1998
The cDNA of the microsomal Juvenile Hormone Epoxide Hydrolase (JHEH) from Manduca sexta was expressed in vitro in the baculovirus system. In insect cell culture, the recombinant enzyme (Ms-JHEH) was produced at a high level (100 fold over background EH catalytic activity). As expected, Ms-JHEH was localized in the microsomal fraction with a molecular mass of approximately 50 kDa. Ms-JHEH showed a substrate and inhibitor spectrum similar to the wild type JHEH isolated from eggs of M. sexta. Its enzymatic activity was the highest for Juvenile Hormone III. Ms-JHEH hydrolyzed several trans-epoxides faster than cis-epoxides. A putative hydroxyl-acyl enzyme intermediate was isolated suggesting a …
Internal resources as tools to increase the global competition: the Italian wine industry case
2017
Purpose The purpose of this paper is twofold: first, it identifies distinct organizational models in a sample of small and medium enterprises operating in the Sicilian wine industry; and second, it identifies the key factors enabling a superior export success. Design/methodology/approach Internal resources were analyzed theoretically in order to achieve the aims of the study. Subsequently the empirical investigation was carried out administering a questionnaire to a sample of 102 wineries in Sicily, Italy. A cluster analysis was performed in order to group these firms into homogeneous categories. Findings The findings show that success in the international market is more common among winer…
