Functional approaches to disability measurement in Zambia reveals an overall disability prevalence rate of 13.4%, 4% of whom are recorded as having “speech impairment” (Zambia Federation of the Disabled [ZAFOD], 2006). Further, multidimensional poverty assessments indicate that 48.6% of Zambia's approximately 16 million citizens are impoverished. Currently, there are three internationally qualified speech-language pathologists (SLPs) providing services within Zambia's capital city, Lusaka. Given these statistics, it follows that a significant number of Zambian's, experiencing communication disability, are unable to access specialist assessment and support. Over the past decade, Zambia has seen two very different approaches to address this service gap—firstly, a larger scale top-down approach through the implementation of a formal master's degree program and more recently a smaller scale, bottom-up approach, building the capacity of existing professionals working in the field of communication disability. This article provides an overview of both programs and the context, unique to Zambia, in which they have developed. Authors describe the implementation challenges encountered and program successes leading to a discussion of the weakness and merits to both programs, in an attempt to draw lessons from which future efforts to support communication disability and SLP service development in Majority World contexts may benefit.

The evidence that cigarette smoking and atmospheric pcllution are causes of lung cancer is largely statistical. The first evidence was indirect; that is, i1. was noticed that in many countries the incidence of lung cancer had increased and that the increase could be correlated with changes in the prevalence of cigarette smoking and of certain types of atmospheric pollution.Since then much direct evidence has been obtained. The relationship between cigarette smoking and lung cancer has been demonstrated retrospectively by comparing the smoking habits of patients with and without lung cancer and prospectively by observing the mortality from lung cancer in groups of persons of known smoking habits. Conclusions can be drawn from these studies only after careful examination of the results. In particular it is important in retrospective studies to test a) the reproducibility of the data, b) the representativeness of the data, and c) the comparability of the special series and their controls. The resul1.s of retrospective studies are all similar and all show a close relationship between cigarette smoking and the disease.The results have been confirmed by pro~pective studies which are lesF. open to bias. The results can be explained if cigarette smoking causes lung cancer or if both are related to some third common factor. Ancillary data (pathological changes in the bronchial mucosa, animal experiments, etc.) support the causal hypothesis.The evidence relating to atmospheric pollution is less definite and it is difficult to get direct evidence of a relationship in the individual. It is clear that pollution has little effect in the absence of smoking, but the mortality associated with a given amount of smoking is generally greater in large towns than in the countryside and among men who have emigrated from Britain than among men who have lived all their lives in less polluted countries.

A relative uniformity of population distribution on the territory of the country is of importance from socio-economic and strategic perspectives. It is especially important in the case of Russia with its densely populated West and underpopulated East. This paper considers changes in population density in Russian regions, which occurred between 1897 and 2017. It explores whether there was convergence in population density and what factors influenced it. For this purpose, it uses the data both at county and regional levels, which are brought to common borders for comparability purposes. Further, the models of unconditional and conditional β-convergence are estimated, taking into account the spatial dependence. The paper concludes that the population density equalization took place in 1897-2017 at the county level and in 1926—1970 at the regional level. In addition, the population density increase is shown to be influenced not only by spatial effects, but also by political and geographical factors such as climate, number of GULAG camps, and the distance from the capital city.

In Cambodia, the government's response to the COVID-19 crisis intersected with religious practice this year, as April played host both to the Christian Holy Week and the Cambodian New Year holiday, rooted in Cambodian Buddhism and indigenous religions. Typically, the Cambodian New Year celebration involves the near-complete shutting down of Phnom Penh, allowing for residents of the capital city to spend the New Year with their families in the countryside. Many Christians stay with their parents or other relatives, who remain primarily Theravada Buddhist, in the rural provinces throughout Holy Week, missing Easter Sunday services to participate in New Year's festivities at their ancestral homes. In light of the government's precautionary cancellation of the all-encompassing festivities surrounding the Cambodian New Year this spring, Christians who have previously spent Easter Sunday addressing controversial questions of interreligious interaction notably focused this year, through online broadcasting, on the resurrection of Jesus. In the United States, the near elimination of in-person gatherings has blurred the boundaries between the ministry roles of recognised church leaders and lay Christians, often women, who have long been leading unofficial services and devotionals over the phone and internet. In this article, I argue that the COVID-19 crisis, with its concomitant mass displacement of church communities from the physical to the technological realm, has impacted transnational Cambodian evangelicalism by establishing greater liturgical alignment between churches in Cambodia and in the diaspora, democratising spiritual leadership and increasing opportunities for interpersonal connectedness within the Cambodian evangelical community worldwide.
