Current population theory depends heavily on the hypothesis that a demographic revolution occurred in West European countries roughly between 1750 and 1880. According to this hypothesis, European death rates averaged at least 35 per 1,000 prior to 1750; hence, even very high birth rates did not enable populations to recover rapidly from the effects of catastrophes, which are supposed to have been frequent and intense. Only after the advances, mainly hygienic, which began about 1750 did the death rate commence a long-term decline. Because fertility remained high, West European populations grew more rapidly than they had ever done. Eventually, urbanization and industrialization sapped the forces which maintainted high birth rates, and low fertility became the major cause of low Western rates of growth.Since currently under-developed populations have high vital rates, it has been suggested that demographic principles are transcultural and that Western demographic patterns will be repeated.

Demographic Patterns

While studies of Irish society have concentrated on the effects of colonialism on late industrialisation and Irish social life, less work has been done on the uniqueness of Irish demographic change and its connection to the country's colonial past. The present article argues that Ireland demographic history has more in common with post-colonial societies than with European states that went through the so-called demographic transition. Irish demographic patterns differ even from peripheral societies of Europe, primarily because its historic pattern of emigration allowed for a stable population despite relatively high birth rates and rapidly declining death rates. Ireland's recent economic success, however, has dramatically altered this historic pattern and its vital rates now correspond more closely to the pattern of European countries that experienced an early demographic transition.

Growth Estimation

This paper presents the results of an attempt at estimating the current birth rates in East and West Pakistan. In the absence of an adequate registration system, estimates of vital rates are dependent on alternative sources of data and various techniques of estimation. In the case of Pakistan, where registration systems are extremely defective, the two major alternative sources of data are the Population Growth Estimation (PGE) experiment and the (1951 and 1961) decennial censuses of population. The PGE is an attempt to acquire knowledge of the level of birth and death rates in Pakistan by matching information obtained, for a sample of the population, from periodic surveys and continuous registration of events as they occur [3, pp.37-65]. Preliminary findings from data collected in 1962 indicate, for total Pakistan, a birth rate of 56 and a death rate of 18, resulting in a growth rate of 38 [11]. A subsequent report based on slightly modified data, and presenting results for both sections of the country, indicates a birth rate of 58 and a death rate of 21 for East Pakistan, with a birth rate of 55 and a death rate of 22 for West Pakistani 12].There is reason to believe that the birth rate estimated by the PGE for total Pakistan is a reasonably close approximation of the actual birth rate but that the estimated death rate is too low (and consequently, that the indicated rate of growth is too high)

Of all British colonies New Zealand is the one that most closely resembles Great Britain in size, in situation, and in climate. And the inhabitants of the two countries are of practically the same race. The vital statistics of New Zealand are therefore eminently suitable for comparison with those of Great Britain. In the present paper comparison has been restricted to the birth-rates and death-rates, and in this limited survey several points of interest present themselves.

Literary Sources

The purpose of this paper is to assess the validity of some methods currently being used to interpret the demographic evidence from the ancient world. For example, it has been claimed that during the Hellenistic and Roman eras, birth rates were 40/1,000/year, death rates 36/1,000/year, and that 10% of healthy infants were killed, raising the death rate to 40/1,000/year; the claims rest on comparative material and anecdotes from literary sources. This paper will question (I) the use of comparative material from modern primitive societies as ‘evidence’ for Greece and Rome, and (II) the value of anecdotes for elucidating ancient demographic structure and population policies.

Background: Intracranial atherosclerotic stenosis is a major cause of stroke and yet there are currently no proven effective treatments for it. The SAMMPRIS trial, comparing aggressive medical management alone with aggressive medical management combined with intracranial angioplasty and stenting, was prematurely halted when an unexpectedly high rate of periprocedural events was found in the endovascular arm. The goal of our study is to report the immediate and long-term outcomes of patients with ≥ 70 % symptomatic intracranial atherosclerotic stenosis treated with balloon angioplasty and stent placement in a single centre. Patients and methods: This is a retrospective review of 37 consecutive patients with 42 procedures of ballon angioplasty and stenting for intracranial atherosclerotic stenosis (≥ 70 % stenosis) treated between 1999 and 2012. Technical success (residual stenosis ≤ 50 %), periprocedural success (no vascular complications within 72 hours), and long-term outcomes are reported. Results: Technical and periprocedural success was achieved in 90.5 % of patients. The within 72 hours periprocedural stroke/death rate was 7.1 % (4.8 % intracranial haemorrhage), and the 30-day stroke/death rate was 9.5 %. Thirty patients (81 %) had clinical follow-up at ≥ 6 months. During follow-up, 5 patients developed 6 ischemic events; 5 of them (17 %) were ipsilateral. The restenosis rate was 27 %, and the retreatment rate was 12 %. Conclusions: Our outcomes of the balloon angioplasty/stent placement for intracranial atherosclerotic stenosis are better than those in the SAMMPRIS study and compare favourably with those in large registries and observational studies.

On Farm

Agroforests and woodlots offer Northland hill country farmers investment and diversification opportunities. Agroforests have less effect on the "whole farm" financial position than woodlots, especially where a progressive planting regime is adopted and where no further borrowing is required. Establishment and tending costs for agro-forests are lower, and returns come much sooner. The proven opportunity for continued grazing under trees established in this manner, apart from a short post-planting period, further enhances the agroforesty option. Even where there is reluctance on a farmer's part to plant trees on high fertility land, the expected financial returns from agroforests on low and medium fertility land will increase the overall long-term profitability and flexibility of the whole farming operation. Woodlots may be more appropriate on low fertility areas where weed reversion is likely. Joint ventures may be worth considering where farm finances are a limited factor.

Sivash bay is the shallow-water lagoon of the Azov Sea. Restricted water exchange and high evaporation form Sivash as the basin with very high salinity. This factor leads to different from the Azov Sea thermal and ice regimes of Sivash. Maine aim of the study presented to investigate recent state and changes of the characteristics and processes in the basin using satellite data. Landsat scanners TM, ETM+, OLI, TIRS together with MODIS and AVHRR were used. Additionally NOMADS NOAA and MERRA meteorological data were analyzed. The next topics are discussed in the work: 1. Changes of the sea surface temperature, ice regime and relation with salinity. 2. Coastal line transformation – long term and seasonal, wind impact. 3. Manifestation of the Azov waters intrusions through the Arabat spit, preferable wind conditions.

The Impact

BACKGROUND The impact of climate temperature on the counts (number of positive COVID-19 cases reported), recovery, and death rates of COVID-19 cases in South Africa's nine provinces was investigated. The data for confirmed cases of COVID-19 were collected for March 25 and June 30, 2020 (14 weeks) from South Africa's Government COVID-19 online resource, while the daily provincial climate temperatures were collected from the website of the South African Weather Service. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that no particular temperature range is closely associated with a faster or slower death rate of COVID-19 patients. As evidence from our study, a warm climate temperature can only increase the recovery rate of COVID-19 patients, ultimately impacting the death and active case rates and freeing up resources quicker to enable health facilities to deal with those patients' climbing rates who need treatment. OBJECTIVE This study aims to investigate the impact of climate temperature variation on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperature values. METHODS The data for confirmed cases of COVID-19 were collected for March 25 and June 30 (14 weeks) for South African provinces, including daily counts, death, and recovery rates. The dates were grouped into two, wherein weeks 1-5 represent the periods of total lockdown to contain the spread of COVID-19 in South Africa. Weeks 6-14 are periods where the lockdown was eased to various levels 4 and 3. The daily information of COVID-19 count, death, and recovery was obtained from South Africa's Government COVID-19 online resource (https://sacoronavirus.co.za). Daily provincial climate temperatures were collected from the website of the South African Weather Service (https://www.weathersa.co.za). The provinces of South Africa are Eastern Cape, Western Cape, Northern Cape, Limpopo, Northwest, Mpumalanga, Free State, KwaZulu-Natal, Western Cape, and Gauteng. Weekly consideration was given to the daily climate temperature (average minimum and maximum). The recorded values were considered, respectively, to be in the ratio of death-to-count (D/C) and recovery-to-count (R/C). Descriptive statistics were performed for all the data collected for this study. The analyses were performed using the Person’s bivariate correlation to analyze the association between climate temperature, death-to-count, and recovery-to-count ratios of COVID-19. RESULTS The results showed that higher climate temperatures aren't essential to avoid the COVID-19 from being spread. The present results conform to the reports that suggested that COVID-19 is unlike the seasonal flu, which does dissipate as the climate temperature rises [17]. Accordingly, the ratio of counts and death-to-count cannot be concluded to be influenced by variations in the climate temperatures within the study areas. CONCLUSIONS The study investigates the impact of climate temperature on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperatures as South Africa. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Warm climate temperatures seem not to restrict the spread of the COVID-19 as the count rate was substantial at every climate temperatures. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that there is no particular temperature range of the climatic conditions closely associated with a faster or slower death rate of COVID-19 patients. However, other shortcomings in this study's process should not be ignored. Some other factors may have contributed to recovery rates, such as the South African government's timely intervention to announce a national lockout at the early stage of the outbreak, the availability of intensive medical care, and social distancing effects. Nevertheless, this study shows that a warm climate temperature can only help COVID-19 patients recover more quickly, thereby having huge impacts on the death and active case rates.

Positive emotions include pleasant or desirable situational responses, ranging from interest and contentment to love and joy, but are distinct from pleasurable sensation and undifferentiated positive affect. These emotions are markers of people's overall well-being or happiness, but they also enhance future growth and success. This has been demonstrated in work, school, relationships, mental and physical health, and longevity. The broaden-and-build theory of positive emotions suggests that all positive emotions lead to broadened repertoires of thoughts and actions and that broadening helps build resources that contribute to future success. Unlike negative emotions, which are adapted to provide a rapid response to a focal threat, positive emotions occur in safe or controllable situations and lead more diffusely to seeking new resources or consolidating gains. These resources outlast the temporary emotional state and contribute to later success and survival. This chapter discusses the nature of positive emotions both as evolutionary adaptations to build resources and as appraisals of a situation as desirable or rich in resources. We discuss the methodological challenges of evoking positive emotions for study both in the lab and in the field and issues in observing both short-term (“broaden”) and long-term (“build”) effects. We then review the evidence that positive emotions broaden perception, attention, motivation, reasoning, and social cognition and ways in which these may be linked to positive emotions' effects on important life outcomes. We also discuss and contextualize evidence that positive emotions may be detrimental at very high levels or in certain situations. We close by discussing ways in which positive emotions theory can be harnessed by both basic and applied positive psychology research.
