Perspectives of religious beliefs and family planning by religious leaders and young women: results from a qualitative study of Bobo-Dioulasso and Ouagadougou in Burkina Faso
Amelia Maytan-Joneydi, Kindo Boukary, Fiacre Bazie
et al.
Burkina Faso is religiously diverse compared to its neighbors. Religion and religious leaders are often perceived as being against family planning (FP) use. That said, the literature on different religions and religious leaders’ position on FP does not demonstrate a uniform stance and there is a dearth of perspectives related to use among young people. Qualitative data for this study were collected in July 2022 in Ouagadougou and Bobo-Dioulasso, Burkina Faso. Focus group discussions (FGD) were conducted with Catholic, Protestant, and Muslim young women who were aged 18–24 and were current users of FP. In-depth interviews (IDI) were conducted with pro-FP Catholic, Protestant, and Muslim religious leaders. The FGD and IDI data were translated and transcribed into French, thematically coded, and qualitatively analyzed. Young women of all faiths generally perceived their religions were against FP use for anyone, and especially for unmarried women. There was some openness to FP use by married women for birth spacing, especially with the consent of the husband. When young women were asked about their reasons for using FP despite their perception of their religion’s position against it, married young women said they used FP due to financial and practical difficulties inherent to modern day life, and to promote a more harmonious family life. Unmarried young women used FP to avoid social stigma and to pursue their own studies. IDI with pro-FP religious leaders of all faiths demonstrated their support of FP; they spoke of its benefits. While religious leaders did not say their religion prohibits FP use, they expressed some conditions on their support of FP such as marital status, purpose of FP use, and type of method used. This study shows that while young Christian and Muslim women largely perceive their religion to be against FP use, other factors are considered in their decision to use. While religious leaders remain influential, for young women, societal level pressures are more pressing. Religious leaders and other stakeholders should consider the current needs of young people and their own evolving beliefs around FP in their messages to their communities.
Electron-Ion Equilibration in the Merging Galaxy Cluster A665
Christian Norseth, Daniel R. Wik, Craig L. Sarazin
et al.
Galaxy cluster mergers drive powerful shock fronts that heat the intracluster medium (ICM) and accelerate particles, redistributing the energy in a merger. A665 is one of only a few clusters with such a powerful shock ($\mathcal{M}\sim$3), and it provides a unique opportunity to study the thermalization timescale of the ICM, particularly the electron-ion equilibration timescale. Understanding this timescale is crucial for determining how the energy from the merger is distributed between thermal and nonthermal particle populations. Using $\sim$200 ks of NuSTAR observations, we measure the temperature distribution across the shock to distinguish between two heating models: (1) an instant collisionless model, where ions and electrons are immediately heated at the shock front; and (2) a collisional model, where electrons are initially adiabatically compressed at the shock and subsequently equilibrate with the ions over $\sim$100 Myr. Our measurements favor the delayed-equilibration model, suggesting that electrons do not immediately reach thermal equilibrium with the ions at the shock front and instead equilibrate over $t_{eq} = (4.0 \pm 3.4) \times 10^8$ yr. Additionally, our temperature measurements indicate that the Mach number may be lower than previously estimated ($\mathcal{M} = 2.8 \pm 0.7$), suggesting that the shock strength has been overestimated in past studies. These results add to our understanding of the microphysics governing how thermal energy is distributed in diffuse plasmas like the ICM, with implications for galaxy cluster evolution, large-scale structure formation, and cosmology.

The Importance of a Principal’s Shepherd Leadership in Transforming Teachers' Understanding of the Christian Worldview
Jekoniah Yoel, Novel Priyatna
Shepherd leadership is often understood as a form of leadership that takes place within the Church. However, it can also be effectively implemented in other settings, such as schools. In fact, schools may be one of the most ideal environments for shepherd leadership, as they require significant daily interaction among principals, teachers, and students. Shepherd leadership is especially important in schools because a principal cannot achieve the ultimate goals of education alone. It is therefore critical to have teachers who share the school's vision and mission. The purpose of this study is to explore in greater depth how shepherd leadership can transform teachers' understanding of a Christian worldview in their teaching, and how this transformation relates to discipleship in Christ. This research collects data to reveal how shepherd leadership is implemented in the school, how teachers respond to the principal’s leadership, and how their worldviews are transformed as a result.

Opinions of the population aged 13 and above on interreligious understanding
Wanchai Panjan, Orathai Chuacharoen, Passakorn Ruangvanit
Religion plays a crucial role in fostering long-term national stability, serving as a spiritual anchor for individuals, a source of unity within communities and humanity at large, and a foundation for education, ethics, and moral conduct. It also upholds cultural traditions and helps alleviate human suffering, both physically and mentally. The objectives of this study were: 1) to examine interreligious understanding; 2) to explore the implementation of religious teachings in practice; and 3) to formulate policy recommendations aligned with the National Strategy, the National Reform Plan, the Ministry of Culture’s Strategic Plan, and the Department of Religious Affairs’ Strategic Plan. This study employed a survey research method, targeting Thai citizens aged 13 and above. A total of 15,015 respondents representing five religions—Buddhism, Islam, Christianity, Brahmanism-Hinduism, and Sikhism—from various regions of Thailand were selected. Data were collected using questionnaires and analyzed using frequency, percentage, mean, standard deviation, chi-square, t test, and ANOVA. The results revealed that: 1) overall, 73.57% of respondents demonstrated a good level of interreligious understanding, with Christians showing the highest percentage (91.43%), followed by Sikhs (75.24%), Buddhists (72.93%), Muslims (69.71%), and Brahman-Hindus (68.57%); 2) in terms of implementing religious teachings, 91.20% of respondents reported doing so. Among religious groups, Brahman-Hindus had the highest rate (100%), followed by Muslims (98.38%), Sikhs (98.10%), Christians (96.86%), and Buddhists (90.21%); and 3) the policy recommendations formulated aligned with the National Strategic plans and aimed to promote interreligious understanding and the practical implementation of religious teachings among Thai citizens. Religious teachings can help develop the nation's human resources by promoting religious practice, fostering interfaith understanding, and encouraging the application of religious principles in daily life to build peace and harmony, contributing to sustainable development. To support this, two key actions are recommended: (1) religious institutions should proactively implement community-based plans that use religion to enhance spiritual well-being and empower citizens to address personal and social challenges; and (2) educational agencies should create locally relevant curricula that integrate moral and religious teachings, helping youth connect knowledge with ethical values for everyday life.
Performance Classification and Remaining Useful Life Prediction of Lithium Batteries Using Machine Learning and Early Cycle Electrochemical Impedance Spectroscopy Measurements
Christian Parsons, Adil Amin, Prasenjit Guptasarma
We presents an approach for early cycle classification of lithium-ion batteries into high and low-performing categories, coupled with the prediction of their remaining useful life (RUL) using a linear lasso technique. Traditional methods often rely on extensive cycling and the measurement of a large number of electrochemical impedance spectroscopy (EIS) frequencies to assess battery performance, which can be time and resource consuming. In this study, we propose a methodology that leverages specific EIS frequencies to achieve accurate classification and RUL prediction within the first few cycles of battery operation. Notably, given only the 20 kHz impedance response, our support vector machine (SVM) model classifies batteries with 100\% accuracy. Additionally, our findings reveal that battery performance classification is frequency agnostic within the high frequency ($<20$ kHz) to low-frequency (32 mHz) range. Our model also demonstrates accurate RUL predictions with $R^2>0.96$ based on the out of phase impedance response at a single high (20 kHz) and a single mid-frequency (8.8 Hz), in conjunction with temperature data. This research underscores the significance of the mid-frequency impedance response as merely one among several crucial features in determining battery performance, thereby broadening the understanding of factors influencing battery behavior.

Maintaining an Evangelical Faith in the Face of a Decadent Culture of Democracy
Kelebogile Thomas Resane
Evangelicals living in a democracy are faced with the pressures of constitutionalism and the influence of secularism. These two forces unsettle God from the public spaces and enhance decadent culture. This article addresses the current challenges Evangelicals face in the decadent culture of democracy in South Africa. The essence of the proposal is how South African Evangelicals should maintain their confession, while surrounded by unethical practices of corruption and greed. An interdisciplinary approach is followed, so literature from the disciplines of Church History, Systematic Theology, Ethics, Cultural Anthropology, Sociology, and Political Studies are reviewed to address the problem. The history of the Evangelical faith and the rationale behind Evangelical awakenings open the discussion into the presentation. The Evangelical dogma is highlighted, followed by the definition of democracy with its entrenched decadent culture. Church, government, and the family are identified as places of contestation, where Evangelicals sense the threat to their doctrinal tenets. The challenge faced by Evangelicals can be addressed by remaining evangelically rooted and by holding unswervingly to three major doctrinal tenets, which are the doctrine of the Trinity, the doctrine of human depravity, and in the belief that the Bible is the measure of faith and conduct.

A Study on Religious Education in Families of Family Federation for World Peace and Unification: Focusing on Adolescent Textbooks
Sunyoung Moon
[Objective] This study aims to understand religious education in families of Family Federation for World Peace and Unification (FFWPU), a new Christian religion, with a particular focus on adolescent textbooks utilized in these households. [Contents] The adolescent textbooks, compiled into two volumes, are structured under eight major themes and a total of 52 subtopics. Each subtopic is designed for parents and their adolescent children to read together at home, fostering interaction and dialogue. The major themes of Volume 1 are: (1) Heavenly Parent and True Parents, (2) Self, (3) Interpersonal Relationships, and (4) Dreams and Future. The major themes of Volume 2 are: (1) Love, (2) Family, (3) All things, and (4) Faith. These major themes are based on the worldview of FFWPU, encompassing the primary life purposes and values pursued by the faith community. The textbooks also reflect the unique characteristics of this new religion, including its experience of misunderstanding from mainstream Christianity in Korea and its significant composition of multicultural families within the faith community. Accordingly, the textbooks also emphasize the aspect of religious education aimed at enhancing the self-esteem of adolescents from multicultural families. [Conclusions] Religious education in families of FFWPU emphasizes helping adolescent children form a religious self-identity, establish religious values regarding sexuality, and focus on the practical application of life aimed at developing a complete religious character.
The Role of Religious Organizations in a Multi-Ethnic Region (using the Republic of Dagestan as an Example)
M. A. Magomedova
Introduction. The study focuses on the growing role of religions in the life of North Caucasian society. It shows that such religions as Islam, Christianity and Judaism have a high potential for ensuring social and political stability in the multiethnic region. The main theological contradictions between the currents in Islam is under analysis.Materials and Methods. The theoretical and methodological basis of the research is formed by general philosophical methods and principles, ones of systematicity. The work also uses the methodology of discourse analysis of speeches and statements of political, public and religious figures, content analysis of mass media.Results. In the modern multi-ethnic region, religion and religious organisations play a significant role in the sociopolitical and spiritual and moral spheres. Consequently, the establishment of civilised state-confessional, inter- and intraconfessional relations contributes to the preservation of peace and stability and the consolidation of Dagestan society.Discussion and Conclusion. The problems investigated in this article are not only theoretical but also practical, as Muslim, Christian and Jewish spirituality realise their role and responsibility in maintaining peace and tranquillity in a multi-ethnic, multiconfessional and multicultural region, orient people towards peaceful relations between different peoples and religions, and towards strengthening the common homeland – Russia. Among the important features of multiethnic Dagestan is the high level of Islamic religiosity.
Astronomy of the Earth-Moon system and the Eschatological Expectations of the Christian Historians of the 5th century CE
D. N. Starostin
This is a historian's view of how modern astronomy data can be used to discuss the shifting historical worldview of Late Antiquity. In this article an attemp is made to construct an approximate model of how the cycles of astronomical bodies' visible rotation aaffected the writing of history and self-representation of the Roman empire's powerful people. It is argued that while rare outstanding events like solar eclipses might have caused a short stir in the minds of the rulers and their environment, long-term cycles based on the synchronization of the Moon's phases with the solar calendar and the cycles of the planets lining up in the same disposition (in relationship to the Moon or without this relationship) were the foundation of astronomy-based Christian chronological system. The emergence of the Christian historical worldview in the 5th century was marked by appearance of a significant eschatological strain in it. Historians paid attention not only to the theology-defined signs of the end of the world, but also, as it has been suggested in modern studies, to the some outstanding celestial phenomena. In this paper I would like to address several criteria which may help understand what in the celestial motions interested the astronomers and historians of the 5th century. This paper uses the first approximation of astronomical data for solving the problem of how relevant the skies were for historians, although all numeric parameters are taken from the up-to-date astronomy reference publications. It is an attempt to understand whether the very basic approximations can be related to what historians know from the array of sources available to them. The analysis suggests that there is a whole array of occasions when the dates of astronomical events, received with the help of these basic approximations, coincide with the data from historical sources.
Direct measurement of coherent light proportion from a practical laser source
Xi Jie Yeo, Eva Ernst, Alvin Leow
et al.
We present a technique to estimate the proportion of coherent emission in the light emitted by a practical laser source without spectral filtering. The technique is based on measuring interferometric photon correlations between the output ports of an asymmetric Mach-Zehnder interferometer. With this, we characterize the fraction of coherent emission in the light emitted by a laser diode when transiting through the lasing threshold.

Նազիկ Հարությունյան
Since the independence of the Republic of Armenia, there has been a need to shake off the 70-year-old atheism of Soviet Armenia and create preconditions for the revival of the Christian faith. His Holiness Garegin I, Supreme Patriarch of all Armenians, was one of the prominent figures of that period, decisive for the Armenian people of the 20th century, who undertook the difficult and responsible mission of reviving our people's moral health and sowing rapprochement with their own identity. In his sermons and works, philosophical concepts and their religious interpretations, His Holiness presents the issues of self-knowledge in a new light.Identity, self-description, great sincerity and courage are needed to reveal oneself. Especially when one has a tendency to self-justify. When making an effort for self-knowledge, one must be able to overcome that psychology, otherwise it will close the person's "self-consciousness" like an opaque curtain. Knowledge of the truth is necessary to live the truth in practical life to find true ways. Its people don't know what is good, evil, justice, honesty and beauty, then they cannot find the secret to a happy life.A question arises: aren't philosophy, based on its intellect, and religion, based on its belief, contradictory concepts? After all, many theologians and philosophers have different points of view on these issues. According to His Holiness, the intellect cannot be an obstacle to faith; on the contrary, it is a powerful element in the manifestation of the faith in life. Faith reveals to us the God who is in direct contact with us, but not the God who is the order of thought and concerned only to the intellect.225With this reasoning and logic, ethics can be considered as the basis of religion. But in that case, what's the difference between religion and philosophy (ethics), if both are based on faith and love for God, humanity and self-sacrifice?According to His Holiness's observations, we come to the clear conclusion that knowing oneself, "Know yourself", is always imperative for a person.Philosophy on the basis of reason and religion on the basis of faith are not contradictory.
Driving Forces of the Epidemic: A Polluted and Polluting Planet
Philip J. Landrigan
Nearly 20 million new cancer cases are diagnosed across the world each year. By stressing that the majority of cancers can be prevented, Philip Landrigan focuses on the troubling consequences of pollution on individual, social, and planetary health. Since 1990, reduction has occurred in the traditional forms of pollution associated with deep poverty and in the numbers of deaths caused by these forms of pollution. But the modern forms of pollution–ambient air pollution and chemical pollution–are on the rise, as well as the numbers of deaths due to these forms of pollution. Moreover, the health consequences of pollution are inequitably distributed, with the most significant increases in cancer incidence and mortality occurring in low- and middle-income countries–i.e., the countries least capable of confronting the disease and least well able to afford costly therapies. Finally, the author suggests science-based strategies for pollution control and cancer prevention.
Thriving with Stone Age Minds: Evolutionary Psychology, Christian Faith, and the Quest for Human Flourishing
J. Barrett, P. E. King
THRIVING WITH STONE AGE MINDS: Evolutionary Psychology, Christian Faith, and the Quest for Human Flourishing by Justin L. Barrett with Pamela Ebstyne King. Downers Grove, IL: IVP Academic, 2021. 160 pages, index. Paperback; $20.00. ISBN: 9780830852932. *I was looking forward to reviewing this book for several reasons. Firstly, I have been following the work of Justin Barrett for some time. As a clinical psychologist working in academia in the UK, I taught for several years an undergraduate module in psychology of religion in which I dedicated several hours to his work in cognitive science and developmental psychology of religion. Barrett, formerly director of the Thrive Center for Human Development at Fuller Theological Seminary and, prior to that, director of the Centre for Anthropology and Mind at the University of Oxford, has forged an unlikely career for a person of faith in a subdiscipline of psychology popularly considered the sole preserve of skeptics and nonbelievers. *Secondly, if I carry a bugbear about the empirical psychology of religion, it is that at times it tends to avoid application, a sense of the implications of its findings for human living. In this respect, Barrett's collaboration with Pamela Ebstyne King is a welcome addition to this project. Currently based at Fuller Theological Seminary as executive director of the Thrive Center and Professor of Applied and Developmental Science, King adds applied nuance and some succinct epigrams that bring home the implications of evolutionary psychology in everyday life. *Thirdly, it seems very important to me that people of faith generally, and Christians particularly, continue to explore and write about the field of evolutionary psychology, not least because it is often presented as a competing narrative of even nonliteral readings of the Genesis account, in direct opposition to a benevolent creator and a universe that could be considered in any way purposeful. I have lost count of the number of young adults I have encountered who refuse to consider the possibility of there being a creator, or who have lost faith in God, as a result of reading secular or atheistic accounts of human evolution. *Barrett and King have produced a short and well-informed book designed for any interested intelligent reader. No prior knowledge of evolutionary psychology (EP) is required to follow their train of thought. In the early chapters of the volume, they state clearly the basic principles of EP and how the EP account of what it means to be human is remarkably consistent with the biblical understanding of the hallmarks of human life designed in the image of God. They focus on three overlapping domains of competency that are notably human--sociality, expertise acquisition, and self-control--or, as King pithily summarizes: the human capacities to relate, learn, and regulate (p. 46). The early chapters of the book convincingly argue that there is nothing incompatible with these elements of human nature, properly understood, and the Christian anthropology presented in the Bible. Barrett and King successfully side-step contention or sides of the evolution-creation debate. Their point about the compatibility of evolutionary and theological perspectives is well made, and will be of interest for those who are open to it from any faith or nonfaith perspective. *From there, the authors go on to outline their understanding of flourishing from this evolutionary psychology perspective. They note that human nature, with its social, intellectual, and regulatory capacities, has a dual aspect. On the one hand, these capabilities were forged in response to particular niches in evolutionary history; on the other hand, they offer human beings the possibility of redesigning the very niches which formed us. And therein lies the central dilemma of evolutionary psychology referred to in the title of the book. As a species we find ourselves facing the demands of twenty-first-century industrial life with minds designed to deal with the challenges of living in the stone age. Much of the failure in human thriving can therefore be attributed, the authors argue, to the gap that can open up between the social, intellectual, and regulatory capacities of human nature, and the requirements of the contemporary cultural landscape. *Each of the three capacities of human nature is treated to an entire chapter, examining how they can be inadequate to the demands placed upon them in our current context. Examples include the stretching of our social brain ability to breaking point by large populations, the failure of traditional pedagogies to utilize well-established cognitive biases and heuristics, and the overwhelming of our regulatory ability in the face of relentless advertising. We fail to thrive when the gap between human nature and human niche becomes too great, but human flourishing is promoted when we find ways of closing the gap between how we are designed and how we currently live. Barrett and King offer a raft of practical examples of how Christian faith and practice can contribute to this, such as network closure for socializing young people, age-appropriate education strategies for learning, and religious practices for building self-regulation. With these and many other evidence-based examples, the authors add evolutionary justification and theological depth to a common formulation in various forms of applied psychology, whether in clinical practice or the workplace, namely, that we flourish most when we fit our environment best. *The final two chapters take this proposition to its logical conclusion. Firstly, by querying what all this means for our status as bearers of the divine image, functionally commissioned to love God and one another, and to care for creation as God's representatives on Earth. And secondly, by giving space to a consideration of human purpose and telos. While Barrett and King avoid the suggestion that their book is aimed at those attempting to discern their vocation, the final chapter draws together the threads of their survey of human nature and its implications for flourishing with purpose and calling in life. *The book presents a convincing picture of consilience between evolutionary psychology and Christian theology applied in the real world. However, to my mind, it does leave a crucial question hanging. It is one thing to argue that the outcome of the evolutionary process is compatible with a Christian view of humanity, but what remains unaddressed, in this volume at least, is whether the evolutionary process is compatible with a Christian view of God. After all, this is what bothered Darwin. He was not wary of publication for fear of contradicting a literal reading of Genesis, but because his view of the origins of human life based on industrial-scale bloodshed was difficult to square with the existence of a benevolent creator. Once the conceptual problem of evolutionary creation is settled, the emotional problem of evolutionary creation emerges; the question of evolution morphs into the question of pain and evil. Personally, it would have helped this reviewer to more easily assimilate the message of the book if it had addressed this issue even briefly. But be that as it may, Barrett and King offer a coherent and elegant account of the confluence of evolutionary psychology and Christian faith in the quest for human flourishing, which is well worth reading. *Reviewed by Roger Bretherton, Associate Professor of Psychology, University of Lincoln, UK, and Chair of the British Association of Christians in Psychology.
Rethinking Religious Freedom to Assure Harmonisation of Inter-Religious Life in Indonesia
Mohammad Hazyar Arumbinang
This article provides an in-depth analysis and a critical examination of the human rights protection instrument that does not govern the mechanism to resolve the problem of Freedom of Religion rights violation. This article use normative legal research with statutory and historical approaches. The data will be analysed by using descriptive-analytical analysis. This article reveals that Human Rights Protection, especially on the Right to Freedom of Religion, is still becoming a matter of concern for Indonesia. The right to freedom of religion or belief is a fundamental human right recognised in all the major human rights treaties. However, they are still inter-religious tensions and a lack of protection by the Indonesian Government. For example, the violence exploded in Karubaga, the capital of Tolikara district in Papua province. Dozens of stalls and houses were set on fire, which spread to a nearby mosque, reported as conducted by the members of the Christians Group. The recent incidents happened in Singkil, Aceh. In Indonesia a state with various religious diversity which recognises five religions and one thought, it still does not establish the strict protection of the freedom of religion. The law only provides the mechanism on how to resolve grave human rights violations. On the other side, the protection of the light-categorised violation still cannot be enforced. Based on this analysis, the paper offers practical recommendations and guidance for state officials to enhance the protection of all religious groups in expressing their thoughts and to assure the harmonisation of inter-religion life.
Starting Life and Searching for Life on Rocky Planets
Paul B Rimmer, Sukrit Ranjan, Sarah Rugheimer
The study of origins of life on Earth and the search for life on other planets are closely linked. Prebiotic chemical scenarios can help prioritize planets as targets for the search for life as we know it and can provide informative priors to help us assess the likelihood that particular spectroscopic features are evidence of life. The prerequisites for origins scenarios themselves predict spectral signatures. The interplay between origins research and the search for extraterrestrial life must start with lab work guiding exploratory ventures in the solar system, and the discoveries in the solar system informing future exoplanet observations and laboratory research. Subsequent exoplanet research will in turn provide statistical context to conclusions about the nature and origins of life.
A Survey on Channel Estimation and Practical Passive Beamforming Design for Intelligent Reflecting Surface Aided Wireless Communications
Beixiong Zheng, Changsheng You, Weidong Mei
et al.
Intelligent reflecting surface (IRS) has emerged as a key enabling technology to realize smart and reconfigurable radio environment for wireless communications, by digitally controlling the signal reflection via a large number of passive reflecting elements in real-time. Different from conventional wireless communication techniques that only adapt to but have no or limited control over dynamic wireless channels, IRS provides a new and cost-effective means to combat the wireless channel impairments in a proactive manner. However, despite its great potential, IRS faces new and unique challenges in its efficient integration into wireless communication systems, especially its channel estimation and passive beamforming design under various practical hardware constraints. In this paper, we provide a comprehensive survey on the up-to-date research in IRS-aided wireless communications, with an emphasis on the promising solutions to tackle practical design issues. Furthermore, we discuss new and emerging IRS architectures and applications as well as their practical design problems to motivate future research.
Practical Fully Dynamic Minimum Cut Algorithms
Monika Henzinger, Alexander Noe, Christian Schulz
We present a practically efficient algorithm for maintaining a global minimum cut in large dynamic graphs under both edge insertions and deletions. While there has been theoretical work on this problem, our algorithm is the first implementation of a fully-dynamic algorithm. The algorithm uses the theoretical foundation and combines it with efficient and finely-tuned implementations to give an algorithm that can maintain the global minimum cut of a graph with rapid update times. We show that our algorithm gives up to multiple orders of magnitude speedup compared to static approaches both on edge insertions and deletions.
Recent Advances in Practical Data Reduction
Faisal Abu-Khzam, Sebastian Lamm, Matthias Mnich
et al.
Over the last two decades, significant advances have been made in the design and analysis of fixed-parameter algorithms for a wide variety of graph-theoretic problems. This has resulted in an algorithmic toolbox that is by now well-established. However, these theoretical algorithmic ideas have received very little attention from the practical perspective. We survey recent trends in data reduction engineering results for selected problems. Moreover, we describe concrete techniques that may be useful for future implementations in the area and give open problems and research questions.
A new method for life table and life expectancy calculation
Weidong Huang
The existing life table method needs to calculate the age-specific mortality first, not only has too many and complicated calculation steps, but also introduces the multiple approximation to bring error. This paper redefines the probability of death for the life table as the average probability of death of a group of people born in a certain period at a later time. Based on this definition, a new method for the life table is proposed to obtain the life expectancy, which has the same meaning to that from the traditional life table. Using the Japanese population data to verify the method, the results show that it is consistent with the life expectancy of the birth of the baby, the maximum relative difference is no more than 0.1%, and average relative difference is less than 0.03%. The theory and method of life table described in this paper are simple and easy to understand. The needed data are easy to obtained from statistics, and the calculation is easy, the results obtained are accurate and reliable. It should be a very valuable demographic method for application.
The changing landscape of mission medicine and hospitals in Sub-Saharan Africa
Samuel Adu-Gyamfi, Mariama Marciana Kuusaana, Benjamin Dompreh Darkwa
et al.
Missions have played numerous developmental roles towards the achievement of economic and social advancement including the provision of healthcare. From their entry into Africa, they have employed numerous methods in order to introduce their Christian faith. The construction of schools and hospitals, engagement in public health campaigns, provision of relevant services for the poor, and spearheading the provision of formal education, among others, have been the most effective mechanisms. The activities of missionaries have taken different dimensions as their scope continues to change over time. Nevertheless, existing literature shows little data on the changing landscape of mission medicine and hospitals in Africa. Using a systematic literature review approach, the current study discusses the changing landscape of mission medicine and hospitals in Sub-Saharan Africa. This contribution dwells partly on the missionary theory of medical practice to define most of the services of these faith-based organization (FBOs) in Africa. Findings from the study have revealed that mission hospitals have established schools and training schemes that allow them to train medical personnel to complement the limited number of health personnel on the continent. In the twenty-first century, they have contributed to achieving the targets of the Millennium Development Goals (MDGs) and the Sustainable Development Goals (SDGs), especially aspects that focus on health. It is evident that while the focus, methods, and partnerships have changed, missions in healthcare have not diverted their attention from sharing the gospel of Jesus Christ.
