. A new spatial-frequency image enhancement algorithm via wavelet homomorphic filtering transform is proposed to enhance the contrast of an image. The wavelet analysis coefficients are processed using a high-pass filter to amplify the high spatial frequencies and attenuate the low spatial frequencies. So the object features can be emphasized while the undesired contributions within the image due to light source nonuniformity can be reduced. Experimental results show that this new algorithm can gain better performance in enhancing the local contrast (...) of an image while maintaining its global appearance, in contrast to some representative algorithms.

A new medical image enhancement algorithm based on spatial frequency domain is presented in this article. The medical image is first divided into several sub-images based on dyadic wavelet scale analysis. At each level, different directional sub-band images can reflect the different characteristics of the image. A low-frequency sub-band image maintains the original image content information, and high-frequency sub-band images represent image details such as edges and regional boundaries. The corresponding sub-band images are then enhanced by different Butterworth homomorphic filtering (...) functions, which can attenuate the low frequencies and amplify the high frequencies. A linear adjustment is carried out on the low frequency of the highest level. Then, the wavelet reconstruction course is used to obtain the final enhanced image. Experiments on magnetic resonance images of temporomandibular joint soft tissues have shown that the proposed method can effectively eliminate the non-uniform luminance distribution of medical images. Its performance is much better than traditional Butterworth homomorphic filtering algorithm whether in subjective vision quality or objective evaluations such as detailed information entropy and average gradient.

In China, neither reproduction and parenthood by lesbian couples nor their marital status are regulated or protected by law. In 2020, the first legal dispute in China involving a lesbian couple over custody of their joint baby was heard in court. This study examines the legal and ethical issues that lesbian couples confront when they decide to give birth to a child of their own. These challenges begin with regulatory restrictions on their lawful access to assisted reproductive technology and extend (...) to gaps in the legal establishment of parenthood. We found that the lack of access to legitimate reproductive assistance for lesbian couples in China has caused them to make efforts to circumvent laws and regulations to have a child. However, the legislative gaps later led to ethical dilemmas when resolving disputes over parenthood. This study discusses different accounts of establishing and determining natural parenthood in China and concludes by pointing out the urgent need for change in legislative and sociocultural attitudes toward both assisted reproductive technology and same‐sex relationships, mapping the way forward for lesbian couples to obtain better protection of procreation and parenthood before their marriage is culturally accepted and finally legalized.

This book presents a reading of Martin Heidegger's philosophy as an effort to strike a middle position between the philosophies of Plato and Friedrich Nietzsche. Duane Armitage interprets the history of Western philosophy as comprising a struggle over the meaning of "being," and argues that this struggle is ultimately between materialism and idealism, and, in the end, between atheism and theism. This work therefore concerns the question of the meaning of the so called "death of God" in the context of (...) contemporary Continental Philosophy.. (shrink)

Three times in Book 1 chapter 13 of the Nicomachean Ethics, Aristotle says desire partakes of reason in a way. There is a consensus view in the literature about what that claim means: desire has no intrinsic rationality, but can partake of reason by being blindly obedient to the commands of reason. I argue this consensus view is mistaken: for Aristotle, adult human desire has its own intrinsic rationality, and while it is to be obedient to reason, it is not (...) blind obedience, for when reason tells desire to obey, it includes an explanation supporting its order which desire can at least potentially understand. Thus, the nature of human desire, and also of the characteristic interaction of desire and reason, is much different than it is standardly taken to be. (shrink)

Karl Schmitz‐Moormann argues that the doctrines of God and Creation, usually explicated in Roman Catholic theology by using the analogy of being, must rather be conceived in light of evolution and an analogy of becoming. God the Trinity, characterized by unity, information, and freedom, provides the image toward which the creation tends in its evolutionary processes. Informed by Teilhard and others, the author hereby provides more of a new research program for theology's engagement with natural science than a fully developed (...) theology. (shrink)

Many authors have argued that Aristotle does not stay true to his official account on which every instance of choice must be preceded by deliberation, and it is a good thing that he does so because his official account has catastrophically bad theoretical implications. I argue that Aristotle does not deviate from his official account, and that the official account does not have the decisively bad implications others have claimed it to have. These objectionable entailments only obtain on a certain (...) conception of what deliberation is like, and I argue that this conception is not Aristotle’s. Once Aristotle’s own conception of deliberation is understood, the terrible putative entailments clearly do not follow from the official account, and so textually Aristotle remains consistent while conceptually he remains plausible.

Duane Cady views warism and pacifism as polar extremes on a continuum that embraces a full spectrum of ethical positions on the morality of war and peace. Realizing that he could not intellectually defend the notions of just-war theory, he found that he was a reluctant pacifist. In this new edition of From Warism to Pacifism, Cady continues to expose the pervasive, subconscious warism that is the dominant ideology in modern Western culture. He explores the changes over the last twenty (...) years—from the end of the Cold War to the ongoing “war on terror,” as well as Barack Obama winning the Nobel Prize for Peace. Like racism and sexism, the uncritical presumption that war is morally justifiable, even morally required, misguides our attitudes and institutions. In its place, Cady proposes the development of a positive concept of peace. Citing common objections to pacifist values, he describes peace as something more than the mere absence of war and demonstrates that pacifism is a defensible position. (shrink)

Although the presence or absence of a pitch accent clearly can play an important role in signaling the discourse and information structure of an utterance, whether the form of an accent determines the type of information it conveys is more controversial. We used an eye‐tracking paradigm to investigate whether H*, which has been argued to signal new information, evokes different eye fixations than L+H*, which has been argued to signal the presence of contrast. Our results demonstrate that although listeners interpret (...) these accents differently, their interpretive domains overlap. L+H* creates a strong bias toward contrast referents whereas H* is compatible with both new and contrast referents. (shrink)

Currently, there are two bottleneck problems in the research of college students’ entrepreneurial intention and entrepreneurial behavior: lack of comprehensive and systematic theoretical framework and empirical analysis to reveal the role path that affects entrepreneurial intention, and most studies ignore the gap between entrepreneurial intention and behavior. Based on the literature review, this study adopted the Theory of Planned Behavior as the theoretical framework introduced entrepreneurial situational factors and entrepreneurial implementation intention, and constructed a two-step extended entrepreneurial intention–behavior model. The (...) structural equation was constructed using AMOS24.0 to empirically analyze the antecedent variables of college students’ entrepreneurial intention and the factors influencing entrepreneurial behavior. The empirical results showed that expected material possessions, expected social reputation, expected self-evaluation, mission and responsibility, and career development are the antecedent variables of entrepreneurial attitude. Support from families and friends, college teachers’ views, and the role models are antecedent variables of entrepreneurial subjective norms. Professional ability, entrepreneurial ability, entrepreneurial experiences, and personality traits are the antecedent variables of entrepreneurial perceived behavior control. In the formation stage of college students’ entrepreneurial intention, attitude, subjective norms, perceived behavior control, and entrepreneurial situational factors have significant impacts on the formation of college students’ entrepreneurial intention, while entrepreneurial intention, perceived behavior control, and entrepreneurial situational factors have significant impacts on the transformation phase of entrepreneurial behavior. Entrepreneurial implementation intention plays an intervening role between entrepreneurial intention and behavior of college students. (shrink)

The discrepancy between measures of preferred and actual participation in decision making was used as a measure of ecological dissonance for an organization and then used to assess its relationship to job satisfaction, job involvement, job alienation, and job formalization. Questionnaires were administered to 143 faculty and staff members of Mississippi State University. Correlational analyses indicated mild relationships between the measures of ecological dissonance and job satisfaction, job involvement, job alienation, and job formalization, thus providing support for ecological dissonance theory (...) (see Miller, Topping, & Wells-Parker, 1989). It was concluded that ecological dissonance in participation in decision making was a predictor of workers’ job satisfaction, job involvement, job alienation, and job formalization. (shrink)

Photography in Colorado was encouraged as early as 1861, when newspaper editor William Byers wrote in the Rocky Mountain News, "Secure the shadow, ere the substance perish," and roused the citizenry to take photographs of their families, friends, landscape, homes, and mills in order to document their lives and share them with others.

abstract: Despite the maturing and formalizing of Buddhist-Christian studies as an academic discipline, its practical and pastoral implications are insufficiently addressed. Most of the practical literature to date addresses spiritual care, broadly conceived, within a narrow range of sources and theories. This scoping study identifies three primary resources offered to providers of spiritual care by scholars of Buddhist-Christian studies: an expanded theoretical base for assessment and interpretation, practices for caregiver formation and cultivation, and guidance for care with spiritually fluid people. (...) Scholars of Buddhist-Christian studies could make at least four additional contributions to chaplaincy and spiritual care: a revised telos of care, attention to care as a site of spiritual practice, criteria for salutogenic spiritualities, and refined practices for interreligious and postcolonializing care. These potential contributions require the discipline to carefully consider methodological issues and broaden its range of sources. (shrink)

I offer a novel analysis of the relations between Aristotle’s three species of desire - appetite, temper, and wish - and the three things he says in EN 2.3 lead to pursuit - the pleasant, the beneficial, and the noble. It has long been tempting to think that these trios line up with one another in some way, ideally relating their members in one-to-one fashion. One account, by John Cooper, has gathered prominent adherents, but other authors, notably Giles Pearson, have (...) argued we should give up on even trying to correlate the two trios. I attempt to show that the two trios do relate in interesting ways, but not in a way that correlates their members in a one-to-one fashion. Instead, I argue that both appetite and temper are ultimately for the pleasant, while all things that an agent takes as objects of wish are conceived of as either pleasant, beneficial, or noble. This account conflicts with a dominant understanding of the species of desire as differentiated by their objects. I reply defend the view by showing that there is a second criterion for differentiating the species of desire. (shrink)

In the ethical texts, Aristotle claims that all instances of choice (prohairesis) must be preceded by deliberation, but it is not clear why he believes this. This paper offers an explanation of that commitment, drawing heavily from the De Anima and showing that the account emerging from there complements that of the ethical texts. The view is that the deliberative faculty has the capacity to manipulate reasons combinatorially, while the perceptual/desiderative faculty does not, and choice requires the combinatorial manipulation of (...) reasons.

In lieu of an abstract, here is a brief excerpt of the content:Deep Listening and Virtuous Friendship:Spiritual Care in the Context of Religious MultiplicityDuane R. BidwellA monk asked Zen master Yunmen: “What is the teaching of the Buddha’s entire lifetime?” Yunmen answered:“An appropriate response.”1In a pivotal scene from the 1988 film A Fish Called Wanda, con artist Wanda Gershwitz is fed up—finally—with her partner, Otto West. When his jealousy and ersatz intellectualism repeatedly jeopardize their attempts to steal $20 million in (...) diamonds, Wanda yells: “Now let me correct you on a few things, okay? Aristotle was not Belgian. The central message of Buddhism is not ‘Every Man for Himself.’ And the London Underground is not a political movement. Those are all mistakes, Otto, I looked them up.”2 It’s a funny moment, of course. But Otto’s (mis)understanding of Gautama’s teaching demonstrates a challenge in translating a spiritual-religious tradition from one cultural setting to another. Too often, and usually without intention, we are like Otto; we colonize and domesticate unfamiliar ideas, assimilating them into our existing worldview instead of experiencing and accommodating their challenging differences. Otto’s facile appropriation of Buddhism confirms rather than confronts his pre-critical, individualistic, and perhaps Darwinist worldview. A Buddhist caregiver might say that Otto was not “listening deeply” to the myriad voices that shaped his perspective.Similar hazards face someone writing about deep listening in relation to religious multiplicity.3 Deep listening, as a caring practice, “belongs” to the emerging field of Buddhist contemplative care,4 in which it has a technical (although perhaps undertheorized) usage richly informed by Buddhist thought and practice. But when I reflect as a pastoral theologian and spiritual caregiver trained in the Christian traditions of cura animarum, the cure or care of souls, deep listening can become unmoored from its origins. Someone marinated in the discourses and practices of Christian care can easily and perhaps unintentionally conflate deep listening with classic Christian [End Page 3] concepts of care such as the ministry of presence, the practice of unconditional positive regard,5 and the giving of oneself to God for the sake of the care seeker. Although I identify as a Buddhist Christian, habitual Christian views shape my thinking the way a canyon or streambed shapes the flow of water; unless I am attentive to the ways that Buddhist thought and practice seek fissures and carve new channels through the sediment of Christian spiritual care, I risk appropriating or erasing the practices that Buddhist caregivers call deep listening.Mindful of these waters, I want to immerse myself and readers in a particular question: In the context of spiritual care, what happens at the confluence of deep listening and a practitioner’s multiple religious voices? In responding to this question I have three aims: to describe deep listening, to provide a theoretical and experiential account of deep listening in the context of religious multiplicity, and to suggest an image from the Pāli canon that can help practitioners engage religious multiplicity in ways that minimize harm, increase compassion, and realize wisdom. A particular moment in spiritually integrative psychotherapy serves as a touchstone for my reflection; thus, I begin where the canyon creates a slender and fast-moving channel for deep listening: psychotherapy with Julie.6violence, karma, and compassionAt twenty-seven years of age, Julie was a soft-spoken, biracial graduate student who radiated mindful presence. She identifies as Asian American, and with her shaved head and tendency to wear dark colors and dramatic scarves, she might seem a typical LA hipster to other passengers on the commuter train she rode to and from our appointments. One year before our psychotherapeutic work, Julie had been beaten and raped by a boyfriend; subsequent thoughts of suicide led to a brief hospitalization. At that time she was assigned diagnoses of bipolar II and post-traumatic stress disorders. Daily, she swallowed a powerful mood stabilizer; monthly, she visited a psychiatrist. The symptoms of bipolar disorder, substance abuse, addiction, schizophrenia, depression, and suicide were present in her extended family. Julie sought counseling because of tension between what she called her “Buddhist identity” and the mental health diagnoses assigned to her. She said she... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Practicing the Religious Self: Buddhist-Christian Identity as Social ArtifactDuane R. BidwellIt is somewhat paradoxical to write or speak about identity formation in two religious traditions that ultimately deny the reality of any identity that we might claim or fashion for ourselves. In the Christian traditions, a person’s true (or ultimate) identity is received through God’s action and grace in baptism; to foreground any other facet of the self, or (...) to anchor identity in anything but baptism, could be considered a form of idolatry. In the Buddhist traditions human identity is empty, woven not from an inherent or externally granted essence but through the interdependent arising of all things; 1 to cling to self and to identity as independent, enduring, immutable, or autonomous signals a mistaken understanding of reality.2 Indeed, as religious scholar Alice Keefe has written, “belief in the self as independent and self-existent is our fundamental delusion and root poison.” 3Yet day by day most of us experience our identities, including our religious, cultural, and social identities, as neither empty nor erased. On the contrary: they seem to be inscribed with enduring meaning. Knowledge has been chiseled into them through our participation in the rituals and relationships of the world. At times the very fullness of our identities can feel on the verge of overflowing. This sense of dynamic presence and fullness causes our identities to serve as important (and perhaps essential) tools for negotiating the hurly-burly of experience and relationship in the mundane, finite, material world.4 From this perspective, our religious identities are social artifacts, entities and meanings formed in between, or on the margins of, biological selves that are related to one another through communities of practice.5 These communal artifacts may then be interiorized by individuals as resources that can be employed in or offered back to the world—performed, if you will—through particular (and sometimes disciplined) practices.6The primacy of social process in creating and maintaining religious identity implies that community remains central to the process of fashioning the religious self in contemporary Buddhist and Christian practice. If this is true, it raises, of course, important questions about our understandings of ecclesiology and the nature of the sangha, theological anthropology and Buddhist understandings of the person. These questions [End Page 3] deserve to be answered, but they are too broad to be addressed here. My more modest intention is to contribute to generative conversation about religious identity formation by illustrating how my own religious identities as Buddhist and Christian have been practiced and performed as social artifacts in two particular instances. In a secondary sense, this essay serves as a reflection on pastoral work in a multifaith context, something “much needed in the Buddhist-Christian studies milieu.” 7Given the diverse academic approaches to Buddhist-Christian studies, it seems wise to begin by describing my own background and approach. By training I am a pastoral theologian, someone who seeks to understand critically the richness and complexity of human experiences and then to respond with appropriate, faithful, and effective acts of care. The psychological meta-theory of social constructionism serves as a primary conversation partner for my work; it invites me to ask “not what goes on ‘inside’ people, but what people go on inside of.” 8 For pragmatic reasons I tend to utilize David Tracy’s mutual critical (or revised) correlational method,9 and in the dialectic between understanding human experience and responding to it, I privilege liberationist theologies and religio-ethical norms of justice, love, and wisdom. My practice as a spiritual director and pastoral counselor seeks to promote practices of freedom for all people.10As a minister in the Presbyterian Church (USA) I am accountable to the Reformed tradition of Christian theology. My formal theological education occurred in the ecumenical context of a divinity school affiliated with the Christian Church (Disciples of Christ) and at a diocesan seminary affiliated with the contemplative Anglican tradition. My informal training in Buddhist philosophy and practice occurred in the Theravada traditions of Southeast Asia, primarily through five years of participation in an immigrant congregation and weekly study with Thich Phap Nhan, a Vietnamese monk...

Summary The optical quality and properties of over 200 telescopes residing in museums and private collections have been measured and tested with the goal of obtaining new information about the early development of the achromatic lens (1757–1770). Quantitative measurements of the chromatic and spherical aberration of telescope objective lenses were made and are discussed within the context of John and Peter Dollond's description of their efforts to overcome these two optical defects inherent in any single lens. Their work was chronicled (...) in the Philosophical Transactions of 1758 and 1765. An important finding of this investigation is that a particular form of the achromatic lens that has been suggested as being a rare and early form by some investigators, and presumably introduced by Chester Moor Hall, was in fact found to be numerous and present in most museums and many private collections. It is shown that the colour correction of an early eighteenth-century doublet telescope objective is very sensitive to the ratio of the flint to crown glass focal lengths, as well as the variations of the indices of refraction with colour. This sensitivity would preclude any simple recipe for constructing an achromatic lens. The third order theory of spherical aberration of Nevil Maskelyne is reexamined, in which he pointed out that John Dollond developed a theoretical formula equivalent to what today is called geometric third order spherical aberration theory.

A Great Plains land ethic is shaped by an intimate knowledge of and appreciation for the evolution, ecology, and aesthetics of the plains landscape. The landscape evokes a sense of wonder and mystery suggested by the word "sacrament." The biblical concept of "covenant" points to God as a community-forming power, a creative process that has evolved into the earth community to which we humans belong. In contrast to an anthropocentric ethic which emphasizes human dominion over nature, a Theo-centric land ethic (...) seeks a balance, reflected in Genesis 1–3, between humans who are members of the earth community and moral agents accountable to God for the earth. A land ethic identifies concrete practices of metanoia and healing: agricultural practices to address the loss and degradation of soil; conservation and protection of water sources; utilization of wind and solar energy; and prescribed burning to restore processes vital to the prairie ecosystem. The concept of subsidiarity suggests that practices of metanoia and healing are a combination of wise public policy balanced by personal, family, church, business, and community responsibility.

For centuries, outside business organizations have sought to enter into business relationships with indigenous populations, often benefitting both parties. However, the power imbalance that foreign settlers had over indigenous peoples often led to exploitative relationships whereby the indigenous people were marginalized and at times treated inhumanely. While the nature of trade and relationships has changed over time, the special status that native tribes enjoy in U.S.A. continues to attract attention from business enterprises. In the past few years, various organizations have (...) found it advantageous to their business interests to engage in transactions with Native American tribes. Three specific examples are described: Allergan transferred patent rights to a tribe to circumvent a U.S. patent review panel; Tesla opened a store and service center on native land in New Mexico to get around the state’s dealership laws; and Lume Cannabis Co. opened retail stores on native lands in Michigan near communities that had decided to not license recreational cannabis stores. All three examples raise questions over the ethics of buying access to native sovereignty. Students are asked to apply ethical theories to try and identify what distinguishes ethical and unethical transactions. (shrink)

In this work of philosophy, theology, and intellectual history, Duane Armitage offers a clear interpretation of Heidegger’s enigmatic theology as uniquely Pauline and Lutheran. He argues that the real impetus, aim, and structure of Heidegger’s philosophy of religion as well as his philosophy as a whole, are rooted in Pauline (and Lutheran) ontology. He thus demonstrates that continental philosophy of religion, and, to an extent, continental philosophy as a whole, is indebted to St. Paul and Martin Luther. This examination also (...) shows how much of continental thinking itself is traceable to Heidegger’s onto-theological critique and hence to Luther and St. Paul. Armitage argues that St. Paul and Luther remain the un-thought origins of postmodern thinking on religion, and perhaps postmodern thinking in general. (shrink)

This essay argues that Heidegger’s theological thinking, best expressed by his “last god” from his 1930s Contributions to Philosophy, is a radicalization of his early Pauline phenomenology from the 1920s. I claim that Heidegger’s theological thinking, including his onto-theological critique, is in no way incompatible with Christian philosophy, but in fact furthers the Christian philosophical endeavor. The tenability of this thesis rests on disputing three critiques of Heidegger’s theology put forth by John D. Caputo, Richard Kearney, and Jean-Luc Marion, all (...) of whom argue that Heidegger and Christianity are incompatible. (shrink)
