Abstract. The analysis of the foF2 ionosonde data acquired at mid and high latitudes reveals a general decreasing of the F2 plasma frequency over more than two solar cycles, showing steeper trends over the high latitude stations and, in particular, over Antarctica. A careful analysis of the foF2 hourly data, opportunely catalogued in different levels of magneto-ionospheric conditions, highlights the role of the geomagnetic activity in the secular change of the ionosphere and confirms the latitudinal dependence of the trends. These results suggest interesting relations with some recent findings on the rapid decrease of some important physical and statistical quantities related to the geomagnetic field over the whole globe and mainly in Antarctica. In this paper we discuss the possibility of a connection between the ionospheric trends and a possible imminent geomagnetic reversal or excursion.

Temperament is probably an important factor that influences coping activity. The framework of the study was the Regulative Theory of Temperament by Strelau, where six temperamental traits are distinguished: emotional reactivity, perseveration, activity, briskness, sensory sensitivity, and endurance. These traits were hypothesized to be connected to coping activity in accordance with their psychological characteristics. It was also expected that the associations between temperament and coping activity should depend on stress intensity. Participants were 278 diabetics and 232 patients after first myocardial infarction (MI). The study was longitudinal and two diseases had been purposely selected so as to represent stress intensity either increasing (in diabetes) or decreasing (after MI) over time. Temperamental traits as well as coping activity components: cognitive appraisal, affect, and coping strategies were measured using self-report questionnaires. As hypothesized, temperamental traits were connected to coping activity. Phase-related changes in coping activity confirmed an increase in stress levels in diabetics, while cardiac patients tended to experience the situation as more challenging. While the expectation referring to the differential role of temperament under different levels of stress intensity was not confirmed, the connections of temperament with coping activity were found to decrease under long-term stress.

The assessment of changes in air pollution quality for 4 selected sites in Southern and Central Poland was presented in this paper. The evaluation was based on the sets of long-term data, recorded by the state air monitoring network. Concentrations of O3, PM10, SO2, NOx, and CO, were considered. The basis for the calculations were 12-year time series of hourly concentrations. Using the hourly data, the monthly averages were calculated to illustrate seasonal changes of pollutant concentrations. Linear trends were adjusted to the concentration courses with the least squares method. Long-time trends were calculated for each pollutant separately. Based on the analysis of the trend lines slopes, risks those may arise in the future were identified.

This paper examines the role of Canada in world forest resource production. A broad overview of global timber supply is presented together with an overview of likely future sources. The discussion covers both regions of supply as well as the nature of the forest resource — old growth, second growth, and plantation forest. Within this broad perspective some long-term trends and tendencies are identified. The growing role of plantation and intensively managed forestry is discussed. Canada's strengths and liabilities as a forest resource supplier are discussed within this context. It is argued that Canada cannot compete successfully with semi-tropical regions in intensive forest management. Rather, Canada appears to have the features necessary to compete in world wood markets using a strategy of extensive forestry that takes advantage of Canada's vast forest land areas.

This article examines the consequences of the latest round of EU-Enlargement in May 2004 on irregular migration across Central and Eastern Europe. Drawing on a unique collection of both quantitative and qualitative data related to irregular migration and human smuggling, the article first presents some long-term trends in irregular migration across the region before taking up more recent developments in 2003 and 2004. While border apprehensions have broadly declined since about 2000 there is ample evidence for an increasing role of human smugglers in facilitating irregular migration. In addition, there are noticeable changes in the modus operandi of human smugglers.

THE SPECIAL ARTICLE by Stewart and Pennell, "Pediatric Manpower in the United States and Its Implications," is interesting and timely. It will be viewed differently by various readers, by some as seen from their personal perch, by others in terms of the broad reaches past and present of pediatrics as a discipline. The purposes of the Special Article are to highlight the manpower situation and to point out long-term trends and implications in the light of the growing responsibility of pediatrics. The authors say that one requires a "delineation of the role of the specialty of pediatrics in child health care," and "while this role may be shared by other types of physicians, the responsibility for the development, maintenance, and improvement of child health services was clearly assumed by pediatrics when, as a specialty, it adopted as its objectives the protection and promotion of the health of children."

The Impact

Although normative questions about the role of the Supreme Court as a countermajoritarian institution have long excited controversy in democratic theory, empirical questions about how far the Court acts contrary to majoritarian opinion have received less attention. Time series analyses for the period 1956–89 indicate the existence of a reciprocal and positive relationship between long-term trends in aggregate public opinion and the Court's collective decisions. The Court's ideological composition changes in response to previous shifts in the partisan and ideological orientation of the president and Congress. The Court also responds to public opinion at the margins even in the absence of membership change. Since 1981, the relationship has vanished or turned negative in direction. The Court's ideological balance has been upset by an unbroken string of conservative-to-moderate appointments, thereby undermining the dynamics that promote judicial responsiveness and raising questions about the majoritarianism of the contemporary and future Court.

ObjectivesModels based on the multistage theory of cancer predict that rates of malignant mesothelioma continuously increase with time since first exposure (TSFE) to asbestos, even after the end of external exposure. However, recent epidemiological studies suggest that mesothelioma rates level off many years after first exposure to asbestos. A gradual clearance of asbestos from the lungs has been suggested as a possible explanation for this phenomenon. We analysed long-term trends of pleural and peritoneal cancer mortality in subjects exposed to asbestos to evaluate whether such trends were consistent with the clearance hypothesis.MethodsWe used data from a pool of 43 Italian asbestos cohorts (51 801 subjects). The role of asbestos clearance was explored using the traditional mesothelioma multistage model, generalised to include a term representing elimination of fibres over time.ResultsRates of pleural cancer increased until 40 years of TSFE, but remained stable thereafter. On the other hand, we observed a monotonic increase of peritoneal cancer with TSFE. The model taking into account asbestos clearance fitted the data better than the traditional one for pleural (p=0.004) but not for peritoneal (p=0.09) cancer.ConclusionsRates of pleural cancer do not increase indefinitely after the exposure to asbestos, but eventually reach a plateau. This trend is well described by a model accounting for a gradual elimination of the asbestos fibres. These results are relevant for the prediction of future rates of mesothelioma and in asbestos litigations.

Abstract The novelty of this research is to prove that the community has been unable to encourage and motivate entrepreneurship growth to improve the economy of indigenous peoples in Papua. This research was carried out in-depth in Papua using descriptive qualitative methods using extensive interviews, observations, and secondary data techniques. The results of the study show that the efforts of the Indonesian Christian Church in Papua to improve the economy of indigenous peoples at both synods, classical, and community levels are still small. The community is currently facing challenges internally and externally. You are grappling with the global Covid-19 pandemic situation. Internet problems still exist in many areas of Papua, making communication even more difficult. To improve the economy of the indigenous peoples, the community tries to implement a common empowerment strategy and strategic steps, namely an open heart-to-heart dialogue between all church components internally at different levels. What is required is a concrete problem mapping with a priority scale and the ability to implement strategic indigenous economic development programs, and supported by appropriate support according to the regional or usual context. At the same time, the community must prepare competent human resources in its areas for long-term economic development.
