The Convergence Degree of Innovation Potential of Romanian Economy, by Comparison with the Developed Economies of the EU Member States
In this paper we analyze the convergence degree of innovation potential of Romanian economy, by comparison with the developed economies of the economical and monetary union, on one hand, and with the last wave of integration countries ā in most cases, economies in process of development, therefore with an economical development trajectory like our country ā on the other hand. The European Innovation Scoreboard (EIS) is the instrument developed at the initiative of the European Commission, under the Lisbon Strategy, to evaluate and compare the innovation performance of the EU Member States. The EIS includes innovation indicators and trend analyses for the EU Member States, plus the two new Member States: Bulgaria and Romania, as well as for Croatia, Turkey, Iceland, Norway, Switzerland, the US and Japan. The Summary Innovation Index gives an āat a glanceā overview of aggregate national innovation performance. It measures 5 key innovation dimensions: Innovation drivers, Knowledge creation, Diffusion, Applications and Intellectual property.innovation; Summary Innovation Index; research; knowledge creation
A new proposal for efficiency quantification of capital markets in the context of complex non-linear dynamics and chaos
The main purpose of this paper is efficiency analysis as well as its
quantification in the case of emerging capital markets, by building
a new measure of market efficiency. The basic assumption of such
markets is the lack of correlation between returns, and therefore the
existence of low entropy, the lack of randomness, manifestation of
fractality and long-term memory, integrated into a single measure,
will indicate the distancing from the state of efficient market. This
paper proposes five different estimates (for informational entropy,
run test, Hurst exponent, long-term correlation coefficient and fractal
dimension) to construct a new measure of market efficiency based on
a deviation from the ideal state (expressed by the efficient market).
The Capital Market Efficiency Exponent is estimated for nine emerging
capital markets and, for comparison, for three developed capital
markets, at different stages of development over a 16-year time span
Discretionary vs nondiscretionary in fiscal mechanism ā nonautomatic fiscal stabilisers vs automatic fiscal stabilisers
The goal of the present study is to increase the intelligibility of
macroeconomic phenomena triggered by governmental intervention
in economy by means of fiscal policies. During cyclical movements,
fiscal policy can play an important role in order to help stabilise the
economy. But discretionary policy usually implies implementation lags
and is not automatically reversed when economic conditions change.
In contrast, automatic fiscal stabilisers (SFA) ensure a prompter, and
self-correcting fiscal response. The present study aims to tackle the
topic of discretionary vs nondiscretionary characteristic of fiscal
stabilisers (SF). In this context, the scope of the research undertaking
is to launch a scientific debate over the definitions of the concepts
of non-automatic fiscal stabilisers (SfnA) and SFAs. We describe how
we can quantify the discretionary and non-discretionary character of
the fiscal policy, by the analysis of the structure of the conventional
budget balance (SBc), budget balance associated with the current
GDP. In the final part of this article, we propose a quantitative
equilibrium model for establishing the mathematical prerequisites
for an SF to become automatic. Likewise, on the basis of the proposed
mathematical model we have performed a qualitative analysis of the
influence factors
Design, Synthesis and Biological Activity Evaluation of S-Substituted 1H-5-Mercapto-1,2,4-Triazole Derivatives as Antiproliferative Agents in Colorectal Cancer
Colon cancer is a widespread pathology with complex biochemical etiology based on a significant number of intracellular signaling pathways that play important roles in carcinogenesis, tumor proliferation and metastasis. These pathways function due to the action of key enzymes that can be used as targets for new anticancer drug development. Herein we report the synthesis and biological antiproliferative evaluation of a series of novel S-substituted 1H-3-R-5-mercapto-1,2,4-triazoles, on a colorectal cancer cell line, HT-29. Synthesized compounds were designed by docking based virtual screening (DBVS) of a previous constructed compound library against protein targets, known for their important role in colorectal cancer signaling: MEK1, ERK2, PDK1, VEGFR2. Among all synthesized structures, TZ55.7, which was retained as a possible PDK1 (phospholipid-dependent kinase 1) inhibitor, exhibited the most significant cytotoxic activity against HT-29 tumor cell line. The same compound alongside other two, TZ53.7 and TZ3a.7, led to a significant cell cycle arrest in both sub G0/G1 and G0/G1 phase. This study provides future perspectives for the development of new agents containing the 1,2,4-mercapto triazole scaffold with antiproliferative activities in colorectal cancer
Perception of disease, dyadic coping, and the quality of life of oncology patients in the active treatment phase and their life partners: an approach based on the actor-partner interdependence model
ObjectiveThe aim of this study based on the Systemic Transactional Model was to examine the relationship between dyadic coping and (1) disease perception and (2) quality of life of a sample of cancer patients and their life partners.MethodThis cross-sectional study included 138 oncological dyads. The following questionnaires were used: Stress Appraisal Measure, Dyadic Coping Inventory, and European Organisation for Research and Treatment of Cancer QLQ-C30. Data collected was analysed by applying the actor-partner interdependence model.ResultsThe perception of the disease as a threat as well as its centrality significantly negatively influences the positive forms of dyadic coping whilst the perception of the disease as a challenge has a significant positive influence on them. Dyadic coping does not influence symptoms but has significant influences on global health/quality of life.ConclusionThis study has highlighted new information regarding how couples cope with cancer. The results encourage the inclusion of the perception of the disease and dyadic coping in interventions that aim to improve the quality of life of cancer patients and their life partners
NEPA, a fixed oral combination of netupitant and palonosetron, improves control of chemotherapy-induced nausea and vomiting (CINV) over multiple cycles of chemotherapy: results of a randomized, double-blind, phase 3 trial versus oral palonosetron
Purpose Antiemetic guidelines recommend co-administration
of targeted prophylactic medications inhibiting molecular pathways involved in emesis. NEPA is a fixed oral combination of a new NK1 receptor antagonist (RA), netupitant (NETU 300 mg), and palonosetron (PALO 0.50 mg), a pharmacologically distinct 5-HT3 RA. NEPA showed superior prevention of chemotherapy-induced nausea and vomiting (CINV) compared with oral PALO in a single chemotherapy cycle; maintenance of efficacy/safety over continuing cycles is the objective of this study.
Methods This study is a multinational, double-blind study
comparing a single oral dose of NEPA vs oral PALO in
chemotherapy-naĆÆve patients receiving anthracycline/
cyclophosphamide-based chemotherapy along with dexamethasone
12 mg (NEPA) or 20 mg (PALO) on day 1.
The primary efficacy endpoint was delayed (25ā120 h)
complete response (CR: no emesis, no rescue medication)
in cycle 1. Sustained efficacy was evaluated during the
multicycle extension by calculating the proportion of patients with overall (0ā120 h) CR in cycles 2ā4 and by
assessing the probability of sustained CR over multiple
cycles.
Results Of 1455 patients randomized, 1286 (88 %) participated in the multiple-cycle extension for a total of
5969 cycles; 76 % completed ā„4 cycles. The proportion
of patients with an overall CR was significantly greater for
NEPA than oral PALO for cycles 1ā4 (74.3 vs 66.6 %,
80.3 vs 66.7 %, 83.8 vs 70.3 %, and 83.8 vs 74.6 %,
respectively; p ā¤ 0.001 each cycle). The cumulative percentage of patients with a sustained CR over all 4 cycles
was also greater for NEPA (p < 0.0001). NEPA was well
tolerated over cycles.
Conclusions NEPA, a convenient, guideline-consistent, fixed
antiemetic combination is effective and safe over multiple
cycles of chemotherapy
A Comprehensive Assessment of Apigenin as an Antiproliferative, Proapoptotic, Antiangiogenic and Immunomodulatory Phytocompound
Time and Causality in the Economic Process ā a Critical Approach Based on Consistency Criteria
Our paper proposes a critical analysis based on criteria
of consistency of the fundamental concepts underlying the comprehensive
description of economic process, namely: time, context and causality.
Issues of such action taken by us arise from the existence of the fact that
the emergence of new paradigms, amid an economic complexity, should
include elements of theoretical, instrumental and methodological nature.
Moreover, dominant economic science, at this time (positivist), is subject
to an epistemological imperialism exercised by Newtonian mechanics,
without oneās own epistemology. Regarding the underlying causality
explaining the economic process, we find that, yet at this time, it is a
singular and efficient one (in the Aristotelian sense), but not a
teleological one, so we wonder whether the final causality (purpose form)
may better explain the economic process and his completeness, and in
this sense, the shaping of new paradigms based on premises other than
those already existed, in understanding the economic process
