Pirmsskolas vecuma bērnu matemātisko priekšstatu veidošanās darbībā ar Marijas Montesorī materiāliem
2018
Darba temats: Pirmsskolas vecuma bērnu matemātisko priekšstatu veidošanās darbībā ar Marijas Montesori materiāliem. Pētījuma mērķis: Teorētiski un empīriski pētīt pirmsskolas vecuma bērnu matemātisko priekšstatu veidošanās darbībā ar M. Montesori materiāliem. Teorētiskajā daļā tiek apskatītas, salīdzinātas un analizētas pedagogu un psihologu atziņas par matemātikas jēdzienu, to galvenās īpatnības un attīstība pirmsskolas vecumā. Matemātisko prasmju apguvē bērnu darbības aktivitātei ir sevišķi liela nozīme, bērni mācās caur darbošanos. Tiek raksturots un izpētīts M.Montesori pedagoģijas virziens, tās būtiskākās teorijas atziņas, izpētīts matemātikas materiālu klāsts pirmsskolas vecuma bērnie…
Age and productivity as determinants of firm survival over the industry life cycle
2017
AbstractThis paper contributes to fill the gap between the literature on the determinants of firm survival and the empirical works on the industry life cycle (ILC). Using a representative sample of Spanish firms with 10 or more employees over the period 1993–2009, the role played by firm age and productivity in firm survival is empirically analysed across three stages of the life cycle of forty-seven 3-digit manufacturing sectors. In the ‘early’ stage of the ILC, firm age is negatively correlated with hazard rates while firm productivity is not. Firm productivity is associated with lower hazard in the ‘mature’ stage of the ILC, when competition is primarily efficiency-driven, while firm age…
Assessing infertility-related stress: The factor structure of the Fertility Problem Inventory in Italian couples undergoing infertility treatment
2015
The factor structure of the Fertility Problem Inventory (FPI) and its invariance across gender were examined in Italian couples undergoing infertility treatment. About 1000 subjects (both partners of 500 couples) completed two questionnaires prior to commencing infertility treatment at a private Clinic in Palermo, Italy. Confirmatory Factor Analysis demonstrated that the original factor structure of the FPI was partially confirmed. Two correlated factors (Infertility Life Domains and Importance of Parenthood) were obtained via a post hoc Exploratory Factor Analysis. Finally, the invariance of this factor structure across gender was confirmed. The study supported the relevance of two interre…
Inflation dynamics in a model with firm entry and (some) heterogeneity
2014
We analyse the incidence of endogenous entry and firm TFP-heterogeneity on the response of aggregate inflation to exogenous shocks. We build up an otherwise standard DSGE model in which the number of firms is endogenously determined and firms differ in their steady state level of productivity. This splits the industry structure into firms of different sizes. Calibrating the different transition rates, across firm sizes and out of the market we reproduce the main features of the distribution of firms in Spain. We then compare the inflation response to technology, interest rate and entry cost shocks, among others. We find that structures in which large (more productive) firms predominate tend…
Finding evidence on the innovative or positional character in medium sized manufacturing firms
2002
Through an empirically based study on 65 medium sized manufacturing firms corresponding to 12 industrial sectors and located in the Spanish region of Valencia, we seek in this paper to provide enough evidence about the prevalence of positional, static and myopic values or, instead, innovative, dynamic and open minded principles, among the firms under study. Gathered into three groups of sectors, depending on the scope of demand (weak, medium and strong demand sectors), we conclude that the weak and medium demand sectors are still facing remarkable challenges basically connected to technology issues, despite improvement in other variables directly linked to an innovative character.
Retinal Fundus Multi-Disease Image Dataset (RFMiD): A Dataset for Multi-Disease Detection Research
2021
The world faces difficulties in terms of eye care, including treatment, quality of prevention, vision rehabilitation services, and scarcity of trained eye care experts. Early detection and diagnosis of ocular pathologies would enable forestall of visual impairment. One challenge that limits the adoption of computer-aided diagnosis tool by ophthalmologists is the number of sight-threatening rare pathologies, such as central retinal artery occlusion or anterior ischemic optic neuropathy, and others are usually ignored. In the past two decades, many publicly available datasets of color fundus images have been collected with a primary focus on diabetic retinopathy, glaucoma, age-related macular…
Identity and Access Management for Remote Maintenance Services in Business Networks
2007
Access to information systems across corporate boundaries with high demands to privacy and trust result into ambitious research and development targets. This study provides motivation and a roadmap for approaching integrated security management solutions in a business network of partners with heterogeneous ICT and security infrastructures. We aim at describing specifics of identity and access management in inter-organizational collaboration, and a vision and arguments for identity and access management in a business network. A case study with Metso Paper, Inc., the leading manufacturer of paper machinery and related services, validates the results, thus providing a motivating example of the…
Enterprise content management: An integrated perspective on information management
2005
Konferansebidrag fra 38th Annual Hawaii International Conference on System Sciences, 2005. HICSS 2005 Enterprise Content Management (ECM) is an emerging concept involving numerous software vendors, consultants, and information management practitioners around increasing market potential. However, there exist yet few academic reports on ECM from the viewpoint of organizational system implementations. This article analyses 58, mainly practitioner-oriented, case narratives of ECM projects and implementations to identify a framework of major issues that require managerial attention in organizations. The main areas covered by the framework are: objectives/impacts sought with ECM, enterprise model…

La infravaloración de las ofertas públicas iniciales en el mercado español: empresa familiar versus empresa no familiar
2013
ResumenLa evidencia previa nacional e internacional muestra la infravaloración de las empresas que salen a bolsa a través de una Oferta Pública Inicial (OPI). Este trabajo tiene como objetivo estudiar si este fenómeno también se da en las empresas de carácter familiar y si existen diferencias significativas en la infravaloración respecto de las empresas no familiares. Para ello, analizamos una muestra formada por 59 empresas españolas que iniciaron su cotización en el mercado bursátil español por medio de una OPI en el periodo 1994-2012. Los resultados revelan que se produce un rendimiento inicial medio positivo significativo tanto en las OPI de las empresas familiares como en las OPI de la…
