Tytuł:: A new confidence interval for the odds ratio
Autorzy:: Zielińska-Kolasińska, Zofia
Zieliński, Wojciech

Data publikacji:: 2023-03-15
Wydawca:: Główny Urząd Statystyczny
Tematy:: confidence interval
odds ratio
Opis:: We consider the problem of interval estimation of the odds ratio. An asymptotic confidence interval is widely applied in economics, medicine, sociology, etc. Unfortunately, this confidence interval has a poor coverage probability, significantly smaller than the nominal confidence level. In this paper, a new confidence interval is proposed. Its construction requires only information on the sizes of samples and the sample odds ratio. The coverage probability of the proposed confidence interval is at least the nominal confidence level.

Tytuł:: Towards a target employment rate within age and gender groups
Autorzy:: Jaworski, Stanisław
Zielińska-Kolasińska, Zofia
Powiązania:: https://bibliotekanauki.pl/articles/1917017.pdf
Data publikacji:: 2021-12-08
Wydawca:: Główny Urząd Statystyczny
Tematy:: employment rate
exponential smoothing
forecasting
state space approach
Opis:: Quarterly employment rates in European countries are analysed in terms of the likelihood of achieving a specific employment rate within age and gender groups in a five-year horizon. The German employment rate serves as a benchmark for this research. The likelihood is estimated by a Monte-Carlo simulation based on the class of exponential smoothing models. The research presents a pessimistic prognosis of employment rates in European countries with respect to young and partly to older workers.

Tytuł:: Apoptosis induced by membrane damage in human lymphocytes; effects of arachidonic acid and its photoproducts.

Opis:: The effect of arachidonic acid (AA) combined with UVA irradiation was studied in a model system mimicking phototherapy PUVA (psoralen+UVA) ex vivo in vitro. The contribution of damage to the plasma membrane by PUVA was tested on human lymphocytes derived from healthy donors. The effect of arachidonic acid (AA) combined with UVA irradiation was compared with that of a psoralen photoadduct to AA added to the culture. The adduct, obtained photochemically and purified, was characterized by NMR and MS spectrometry as a cycloadduct of psoralen to the vinylene bond of the acid (AA<>PSO). The reactions of cultured cells, manifested 20 h after treatment by changes in apoptosis and mitochondrial depolarization, were monitored by flow cytometry by tagging lymphocytes with appropriate fluorescent probes. Treatment of lymphocyte suspension within AA doses from 40 to 100 μM gradually induced a shift from Anx-V+ (single positive cells) to late apoptotic, Anx-V+PI+ (double positive cells) in a dose dependent manner. The adduct, AA<>PSO, induced apoptotic changes at a concentration 2-3 times higher than free AA. Combination of psoralen (1 μM ) or arachidonic acid (20-120 μM) with UVA irradiation (2-6 J/cm2) accelerated the plasma membrane changes in a synergic way. Preliminary studies indicated that changes in the transmembrane potential of mitochondria paralleled the apoptosis when cells were treated by AA alone. Our findings showed that UVA radiation of lymphocytes in the presence of arachidonic acid, as in the presence of psoralen, enhanced apoptosis of cells in a synergic manner. Thus, PUVA-induced apoptosis may proceed in part by a still undefined signaling pathway(s) triggered in lymphocyte membranes.
