New theologies developed in tandem with evolutionary biology during the nineteenth century, which have been called metaphysical evolutionisms and evolutionary theologies. A subset of these theologies analyzed here were developed by thinkers who accepted biological science but rejected both biblical creationism and materialist science. Tools from the cognitive science of religion, including conceptual metaphor theory (CMT) and blending theory, also known as conceptual integration theory (CIT), can help to explain the development of these systems and their transformation between the nineteenth and the twentieth centuries. The analysis focuses on several stable and popular blends of ideas, which have continued with some alteration into the twenty-first century. The three blends evaluated here are Progressive Soul Evolution, Salvation is Evolution, and Evolution is Therapy. Major contributors to these blends are the theosophist and theologian Helena P. Blavatsky and psychologist Frederic W. H. Myers, both influenced by the spiritualist movement, particularly the ideas of the spiritualist and biologist Alfred Russel Wallace. The influence of these blends can be seen in the twentieth-century “Aquarian Frontier,” a group of 145 thinkers and organizations identified in 1975 by counterculture historian Theodore Roszak. Part of the appeal of these blends may be seen in their use of metaphors, including the Great Chain of Being and A Purposeful Life is a Journey. The application of the polysemic term evolution in a sense that does much of the theological work of salvation in Christianity can in part be explained by applying the principles of blending theory, including the vital relation “achieve a human scale,” as well as compressions of time and identity. These blends have been successful because they meet the needs of a population who are friendly towards science but disenchanted with traditional religions. The blends provide a satisfying new theology that extends beyond death for a subset of adherents, particularly in the New Age and spiritual but not religious (SBNR) movements, who combine the agency of self-directed “evolution” with the religious concepts of grace and transcendence.

The shift toward modernity has come with many changes that affect religion. This article investigates some of those changes with the aim of showing how Korean Buddhism is adjusting to contemporary spirituality. The article begins with a consideration of the term ‘spiritual, but not religious’ (SBNR), a relatively new designation that indicates the shift a growing number of people are taking away from organized religious institutes towards beliefs and practices that they find more relevant and meaningful. To better understand SBNRs, the research of Mercadante is emphasized. The second half of this article aims to consider Korean Buddhism in the context of modern spirituality. Using Mercadante’s framework, which distinguishes between five types of SBNRs (dissenters, causals, explorers, seekers, and immigrants), an inquiry is carried out into each of these categories to show some of the ways in which Korean Buddhism is engaging with the spiritual and emotional concerns of modern, secular society. Thus, this work aims to show the direction Korean Buddhism is headed in and how it is relevant to modern, spiritual inclinations. Full article

The extensive application of ceramic membranes in wastewater treatment draws increasing attention due to their ultra-long service life. A cost-effective treatment for high-strength swine wastewater is an urgent and current need that is a worldwide challenge. A pilot-scale sequencing batch flat-sheet ceramic membrane bioreactor (ScMBR) coupled with a short-cut biological nitrogen removal (SBNR) process was developed to treat high-strength swine wastewater. The ScMBR achieved stable and excellent removal of COD (95.3%), NH₄⁺-N (98.3%), and TN (92.7%), though temperature went down from 20 °C, to 15 °C, to 10 °C stepwise along three operational phases. The COD and NH₄⁺-N concentrations in the effluent met with the discharge standards (GB18596-2001). Microbial community diversity was high, and the genera Pseudomonas and Comamonas were dominant in denitritation, and Nitrosomonas was dominant in nitritation. Ceramic membrane modules of this pilot-scale reactor were separated into six layers (A, B, C, D, E, F) from top to bottom. The total filtration resistance of both the top and bottom membrane modules was relatively low, and the resistance of the middle ones was high. These results indicate that the spatial distribution of the membrane fouling degree was different, related to different aeration scour intensities demonstrated by computational fluid dynamics (CFD). The results prove that the membrane fouling mechanism can be attributed to the cake layer formation of the middle modules and pore blocking of the top and bottom modules, which mainly consist of protein and carbohydrates. Therefore, different cleaning measures should be adopted for membrane modules in different positions. In this study, the efficient treatment of swine wastewater shows that the ScMBR system could be applied to high-strength wastewater. Furthermore, the spatial distribution characteristics of membrane fouling contribute to cleaning strategy formulation for further full-scale MBR applications. Full article

This study introduced an alternative shortcut biological nitrogen removal (SBNR) process for landfill leachate treatment by developing a novel hydrodynamic sequencing batch reactor (H-SBR). The reactor could enhance the oxygen transfer rate (OTR) and nitrite accumulation ratio (NAR) by modifying internal hydrodynamic turbulence intensity. The average chemical oxygen demand (COD) and total nitrogen (TN) concentrations introduced into the reactor were 660 and 250 mg L⁻¹, respectively, and the average removal efficiencies were 93% (COD) and 96% (TN). The effect of geometric parameters on oxygen transfer was estimated by performing a hydrodynamic model and a nonlinear least square analysis. After correcting the constants (α and β) of mass transfer coefficients (K_La) to values of 0.7361 and 1.2639, the model data fit the experiment well with an R-squared value of 0.99. The OTR improved by up to 30%, and hence, increased the NAR by up to 20% with a reduction of about 0.5 kg N kW⁻¹ for power efficiency. The H-SBR development is innovative because the oxygen transfer efficiency was improved by the hydrodynamic modification of internal turbulence intensity, although not by mechanical equipment or chemical supplements. For the SBNR process, the modification of the reactor configuration for OTR enhancement could significantly improve nitrogen removal efficiency with successful nitrite accumulation. In addition to landfill leachate treatment, the H-SBR process can be employed in the treatment of low C/N ratio wastewaters. Full article

A technical comparison is described between two SPECT systems, one dedicated to cardiovascular studies and one general-purpose, to evaluate the advantages and disadvantages of their use in an organ-specific clinical setting. The comparison was made between a dedicated cardiac SPECT (Alcyone, Discovery NM 530c, GE Healthcare) scanner and a general-purpose one (Discovery NM/CT 670 CZT, GE Healthcare). The two scanners differ in terms of hardware, mainly in the arrangement of the detectors and collimators, which are the main components of SPECT. A standard NEMA phantom was used to characterize the energy resolution, spatial resolution, and sensitivity for the two systems. Then, using a custom-made cardiac phantom, more specific indices were computed to evaluate the quality of cardiac images, such as signal-to-background noise ratio (SBNR), tissue-background contrast-to-noise ratio (TBCNR), and uniformity. Finally, the same indices were computed for clinical images acquired with the two systems from 11 subjects. Alcyone showed superior performance for dedicated cardiac imaging; however, its excellent qualities are aimed only at the study of the heart and only at patients with a low body-mass index, unlike Discovery NM/CT 670 CZT, which can be used for every anatomic district area and for every type of patient.

Often the debates in philosophy of religion are quite disconnected from the empirical data gathered in the sociology of religion. This is especially the case regarding the recent increase in prominence of those identifying as “spiritual but not religious” (SBNR) within an American context. In the attempt to bring these two fields into productive conversation, this essay offers a constructive account of the SBNR in terms of what they reject (i.e., their status as “not religious”) and also what they affirm (i.e., their identity as “spiritual”). In brief, the suggestion is that the SBNR do not reject theism or even common “religious” practices, but instead reject a particular mode of “religion” that is grounded in an authoritative and insular social presence. Alternatively, the SBNR at least seem to affirm a notion of “spirituality” that is broadly consistent with the idea found in historical Christian traditions. After surveying the empirical data and offering a new phenomenological analysis of it, the essay concludes with a suggestion that we need a new category—“religious, but not spiritual” (RBNS)—in order best to make sense of how the SBNR signify in relation to specific hermeneutic contexts and sociopolitical frameworks.

Spiritual struggles are a distinct problem which have implications for psychological, social, emotional and physical health. They are not unique to religious persons; instead both the religiously unaffiliated (Nones) and those who call themselves “Spiritual but not Religious,” (SBNR) have struggles with existential issues common to all humans, and which can be identified as “spiritual”. Nones are a very diverse group and different types of Nones struggle differently. This qualitative study, based on interviews in North America with over 100 Nones, particularly SBNRs, explains the types of spiritual struggles, with many examples and illustrative quotes. Nones’ key struggles are in the areas of Self and Self-in-Relation. This is a vastly under-researched topic which will only grow in importance, given the rapid and continuing rise of the None population. The topic is of concern to social scientists, but is equally important for psychologists, counselors, medical personnel, chaplains and others in the helping professions given that Nones will come to them for assistance.

This paper begins by examining so-called “spirituality movements and/or culture” in Japanese society today. It then focuses on research into spirituality as it relates to Japanese education, and specifically moral education, where, for example, our connectedness to the sublime and lofty is one of the four themes of the new moral education classes introduced into Japanese elementary schools in 2018. It is far from easy, however, to teach such a subject, since Japanese moral education is required to keep its distance from popular spirituality as well as from the institutionalized spirituality of organized religions. Furthermore, the conventional knowledge that underpins modern Japanese moral education struggles to deal with spirituality and the vast range of human existence, including our search for the purpose and significance of life. Accordingly, this paper will examine current work on such issues and attempt to outline the future role that scientific and academic approaches to religion and spirituality might play in moral education in Japan, especially from the viewpoint of human connectedness to nature and the sublime.

In this work, the feasibility of the Shortcut Biological Nitrogen Removal (SBNR) in the anodic chamber of a Microbial Fuel Cell (MFC) was investigated. Thirty day experiments were carried out using synthetic wastewaters with a Total Organic Carbon vs. nitrogen ratio (TOC/N) ranging from 0.1 to 1. Ammonium, nitrite, nitrate, pH, and TOC were daily monitored. Results showed that microaerobic conditions in the anodic chamber favored the development of nitritation reaction, due to oxygen transfer from the cathodic chamber through the membrane. Nitritation was found to depend on TOC/N ratio: at TOC/N equal to 0.1 an ammonium removal efficiency of up to 76% was observed. Once the oxygen supply to the cathodic chamber was stopped, denitritation occurred, favored by an increase of the TOC/N ratio: a nitrite removal of 80.3% was achieved at TOC/N equal to 0.75. The presence of nitrogen species strongly affected the potential of the electrochemical system: in the nitritation step, the Open Circuit Voltage (OCV) decreased from 180 mV to 21 mV with the decrease of the TOC/N ratio in the investigated range. Lower OCV values were observed in the denitritation steps since the organic carbon acted as the energy source for the conversion of nitrite to nitrogen gas. A kinetic analysis was also performed. Monod and Blackman models described the ammonium and the organic carbon removal processes well during the nitritation step, respectively, while Blackman-Blackman fitted experimental results of the denitritation step better.

This paper challenges the “spiritual but not religious” (SBNR) category as a methodological artifact caused by interacting two closed-ended survey items into binary combinations. Employing a theoretically rich approach, this study maps the multiple ways in which the religious and the spiritual combine for emerging adults. Results indicate that most emerging adults have a tacit sense of morality, displaying limited cognitive access to how moral reasoning relates to religious and spiritual orientations. This longitudinal study investigates efforts to raise moral awareness through: exposure to diverse religious and spiritual orientations, personal reflection, and collective discussion. Relative to control groups, emerging adults in this study display increases in moral awareness. We combine the results of these studies to formulate a theoretical framework for the ways in which beliefs, values, and ethical decision-making connect in expressing plural combinations of religiosity and spirituality. The implication is that direct attention to religiosity and spirituality — not avoidance of — appears to facilitate ethical decision-making. Full article
