Comparison of thermal stratification, light attenuation and Chlorophyll-a dynamics between the ends of Lake Tanganyika
2002
Thermal structure, light attenuation, and chlorophyll-a dynamics within the upper 100 m at the northern and southern ends of Lake Tanganyika were measured from August 1995–July 1996. Pronounced variability of thermal structure in time, depth and region were observed. During the dry windy season (June–September), the water column in the south was largely isothermal down to 100 m, while in the north stratification was detectable. Subsequently, in October, cessation of winds coincided with a reestablishment and strengthening of thermal stratification in the south, and a distinct rise of a weakened thermocline in the north was accompanied by an increase in epilimnetic concentrations of dissolve…

Phytoplankton equilibrium phases during thermal stratification in a deep subtropical reservoir
2008
SUMMARY 1. Equilibrium and non-equilibrium hypotheses have often been used to explain observations in community ecology. Published case studies have demonstrated that steady state phytoplankton assemblages are more likely to occur in deep lakes than in shallow mixed ones. 2. Phytoplankton seasonal succession was studied by weekly sampling in Faxinal Reservoir (S Brazil), a subtropical deep, clear, warm monomictic and slightly eutrophic reservoir. This study demonstrated an alternation of steady and non-steady state phases of phytoplankton assemblages with different dominant species during the steady states. 3. During the studied period, three steady states were identified with different dom…
The multidimensional prognostic index (MPI) for the prognostic stratification of older inpatients with COVID-19: A multicenter prospective observatio…
2021
Background: The topic of prognosis in COVID-19 research may be important in adopting appropriate clinical decisions. Multidimensional prognostic index (MPI) is a frailty assessment tool widely used for stratifying prognosis in older people, but data regarding inpatients, affected by COVID-19, are not available. Objectives: To evaluate whether MPI can predict in-hospital mortality and the admission to intensive care unit (ICU) in older inpatients hospitalized for COVID-19 infection. Methods: In this longitudinal, Italian, multi-center study, older patients with COVID-19 were included. MPI was calculated using eight different domains typical of comprehensive geriatric assessment and categoriz…

Optimal Dynamics of Functionality Development in Open Innovation
2009
Abstract Sustainable functionality development has become crucial option for firm's survival in a new paradigm confronting a post-information society. This can be realized by earlier emergence of functionality development. In this context, effective utilization of external innovation resources leads to follower substitution for leader in open innovation. This substitution induces advancements of innovative goods by substituting gratification of their consumption for resistance to them. Thus, optimization of utmost gratification of consumption under certain investment would be crucial for firm strategy. Optimal functionality development dynamics is analyzed in this paper by integrating produ…
Examining the Performance of Brand-Extended Thematic-Content : The Divergent Impact of Avid- and Skim-Reader Groups
2017
Today, the reading online content is a daily habit for many users. In an online environment, users encounter brands, who hope to attract visitors to their online spheres of influence through brand-extended thematic-content. The purpose of this study is to investigate this phenomenon and assess its impact on both the readers of the content and the brands. To do this, we use structural equation modeling to analyze data from two groups, skim readers and avid readers, who vary in terms of the behaviors they invest in the reading of brand-extended thematic-content. The findings reveal that brand-extended thematic-content affects divergently on the brand attitude formation of these two groups. Sp…
Intergenerational support as a reaction to socio-economic crisis: alteration of solidarity within precarious Romanian households
2017
ABSTRACTThis paper addresses the tensions arising from the intersection of norms and practices of support in situations in which intergenerational support is the main household strategy for coping with precariousness in Romania. This paper describes competing meanings of solidarity and reveals gendered experiences of ambiguity with respect to the sustainability of help exchanges within the context of economic vulnerability. Romania displays high public acceptance of intergenerational support, while the country’s deficient social welfare system prompts families to intensify their help exchanges. Findings based on in-depth interviews suggest that private arrangements are compounded by unbalan…
Rationale, design and methods of CTCA-PRORECAD (Computed Tomography Coronary Angiography Prognostic Registry for Coronary Artery Disease): a multicen…
2013
PURPOSE: This study was done to assess the prognostic value of computed tomography coronary angiography (CTCA) in a large multicentre population of patients with suspected coronary artery disease (CAD) and, in particular, its incremental value compared with traditional methods for risk stratification. MATERIALS AND METHODS: This is a retrospective observational study that began in January 2003 conducted on patients with suspected CAD assessed with CTCA on the basis of symptoms (chest pain, dyspnoea) and/or abnormal or equivocal stress test and/or a high cardiovascular risk profile. The participating centres will provide data obtained with CTCA performed with 16-slice or higher equipment. Ex…
