Like several other classes of hormones, the class of plant hormones called auxins exert myriad effects on cell development. While auxins are most noted for inducing cell elongation, they are also involved in cell division, cell differentiation, cell and organ polarity, and wound responsiveness. Consistent with this pleiotropy, is the recent identification of several putative auxin receptors that in theory could represent the primary elements of more than one auxin signal pathway leading to distinct responses or leading in parallel to (...) a single response. Our current working hypothesis is that some auxin‐mediated responses may be mediated by multiple receptors. We describe some of what is known about each of the new putative receptors and elaborate on the hypothesis using the example of cell elongation. Specifically for auxin‐induced elongation, we propose that two rapid events, specific gene transcription and cell wall acidification, are separately mediated by at least two receptors, acting in the nucleus and at the plasma membrane, respectively.

Speaker recognition under mismatched conditions is a challenging task. Speech signal is nonlinear and nonstationary, and therefore, difficult to analyze under realistic conditions. Also, in real conditions, the nature of the noise present in speech data is not known a priori. In such cases, the performance of speaker identification or speaker verification degrades considerably under realistic conditions. Any SR system uses a voice activity detector as the front-end subsystem of the whole system. The performance of most VADs deteriorates at the (...) front end of the SR task or system under degraded conditions or in realistic conditions where noise plays a major role. Recently, speech data analysis and processing using Norden E. Huang’s empirical mode decomposition combined with Hilbert transform, commonly referred to as Hilbert–Huang transform, has become an emerging trend. EMD is an a posteriori, adaptive, data analysis tool used in time domain that is widely accepted by the research community. Recently, speech data analysis and speech data processing for speech recognition and SR tasks using EMD have been increasing. EMD-based VAD has become an important adaptive subsystem of the SR system that mostly mitigates the effect of mismatch between the training and the testing phase. Recently, we have developed a VAD algorithm using a zero-frequency filter-assisted peaking resonator and EMD. In this article, the efficacy of an EMD-based VAD algorithm is studied at the front end of a text-independent language-independent SI task for the speaker’s data collected in three languages at five different places, such as home, street, laboratory, college campus, and restaurant, under realistic conditions using EDIROL-R09 HR, a 24-bit wav/mp3 recorder. The performance of this proposed SI task is compared against the traditional energy-based VAD in terms of percentage identification rate. In both cases, widely accepted Mel frequency cepstral coefficients are computed by employing frame processing from the extracted voiced speech regions using the respective VAD techniques from the realistic speech utterances, and are used as a feature vector for speaker modeling using popular Gaussian mixture models. The experimental results showed that the proposed SI task with the VAD algorithm using ZFFPR and EMD at its front end performs better than the SI task with short-term energy-based VAD when used at its front end, and is somewhat encouraging.

The performance of most of the state-of-the-art speaker recognition systems deteriorates under degraded conditions, owing to mismatch between the training and testing sessions. This study focuses on the front end of the speaker verification system to reduce the mismatch between training and testing. An adaptive voice activity detection algorithm using zero-frequency filter assisted peaking resonator was integrated into the front end of the SV system. The performance of this proposed SV system was studied under degraded conditions with 50 selected speakers (...) from the NIST 2003 database. The degraded condition was simulated by adding different types of noises to the original speech utterances. The different types of noises were chosen from the NOISEX-92 database to simulate degraded conditions at signal-to-noise ratio levels from 0 to 20 dB. In this study, widely used 39-dimension Mel frequency cepstral coefficient features were used, and Gaussian mixture model–universal background model was used for speaker modeling. The proposed system’s performance was studied against the energy-based VAD used as the front end of the SV system. The proposed SV system showed some encouraging results when EMD-based VAD was used at its front end. (shrink)

In this article, a new adaptive data-driven strategy for voice activity detection using empirical mode decomposition is proposed. Speech data are decomposed using an a posteriori, adaptive, data-driven EMD in the time domain to yield a set of physically meaningful intrinsic mode functions. Each IMF preserves the nonlinear and nonstationary property of the speech utterance. Among a set of IMFs, the IMF that contains source information dominantly called characteristic IMF can be identified and extracted by designing a zero-frequency filter-assisted peaking (...) resonator. The detected CIMF is used to compute energy using short-term processing. Choosing proper threshold, voiced regions in speech utterances are detected using frame energy. The proposed framework has been studied on both clean speech utterance and noisy speech utterance. The proposed method is used for voice activity detection in the presence of white noise and shows encouraging result in the presence of white noise up to 0 dB. (shrink)

Canada has a marked shortfall between the supply and demand for kidneys for transplantation. Median wait times for deceased donor kidney transplantation vary from 5.8 years in British Columbia, 5.2 years in Manitoba and 4.5 years in Ontario to a little over 2 years in Quebec and Nova Scotia. Living donation provides a viable option for some, but not all people. Consequently, a small number of people travel abroad to undergo kidney transplantation by commercial means. The extent to which they (...) are aware of the potential risks to their health and the health of the kidney vendors is unclear. Travel abroad to obtain a kidney commercially i.e. transplant tourism (TT), raises ethical issues which include the exploitation of the poor, uncertainty of donor informed consent to nephrectomy, poor clinical care and lack of follow up for the donor, commodification of the body and inequity of access to medical care for donors. Also, TT widens socioeconomic disparities in access to transplantation, differing from the Canadian system of universal coverage for healthcare. The Canadian transplant community has discussed how to respond to patients who plan to travel abroad for TT or return with a purchased kidney. Unease rests in the tension between the duty to care for legitimate Canadian residents and the unwillingness to enable TT. This paper discusses three anonymized cases and the Canadian responses to TT as recorded in academic literature and a formal statement by relevant professional bodies. (shrink)

This book, through extensive textual study, explores the Buddha's and Buddhism's uncompromising and unflinching emphasis on the centrality of ethics as against any pernicious dogmas and metaphysical beliefs, and their attempts to causally relate moral perfection to soteriological or eschatological goal. What is most admirable about Buddhism is that it integrates the vertical development of human consciousness, for which the other is the necessary condition, with the gradual development of morality. It was this emphasis which separated Siddhartha, before he attained (...) the Awakened Wisdom (bodhi), from his teachers - Alara Kalama and Uddaka Ramaputta - and it is for this reason that the Buddha calls himself and his Dhamma Patisotagami, i.e. going against the currents of the prevailing dogmas and pernicious beliefs. In brief, Buddhism is about overcoming of suffering, the greatest evil, through ethicization of human consciousness and conduct, which also takes care of the ethicization of the society and the universe. Besides, some of the essays of this book explore many other themes like Buddhist epistemology, nature of self, time, and intercultural. (shrink)

Cognitive architectures, like programming languages, make commitments only at the implementation level and have limited explanatory power. Their universality implies that it is hard, if not impossible, to justify them in detail from finite quantities of data. It is more fruitful to focus on particular tasks such as language understanding and propose testable theories at the computational and algorithmic levels.

Ethical arguments about caregiver responsibility and the limits of client autonomy rely on best evidence about the risks and benefits of medical interventions. But when the evidence is unclear, or when the peer-reviewed literature presents conflicting accounts of the evidence, how are clinicians and their clients to recommend or decide the best course of action? Conflicting evidence about the outcomes of home and hospital birth in the peerreviewed literature offers an opportunity to explore this question. We present the contrary evidence (...) and describe the social and cultural elements that influence the production of the science of birth, including professional, publication, and critical bias. We then consider how the science of birth has been used an misused in making ethical arguments about preferred place of birth. We conclude with a number of recommendations about the responsible use of the evidence, arguing for an “ethics of information” that can be drawn on to guide caregivers and clients in the use of evidence for clinical decision making.

This article presents material from my ethnographic study in Śringēri, south India, the site of a powerful 1200yearold Advaitic monastery that has been historically an interpreter of ancient Hindu moral treatises. A vibrant diverse local culture that provides plural sources of moral authority makes Sringeri a rich site for studying moral discourse. Through a study of two conversational narratives, this essay illustrates how the moral self is not an ossified product of written texts and codes, but is dynamic, gen dered, (...) and emergent, endowed with historical and political agency and an aesthetic capacity that mediates many normative sources to articulate "appropriate" conduct. In so doing, the essay shows the value of including oral narrative in ethical inquiry, especially in narrative ethics, which, for most part, has focused on written sources. (shrink)

Vedānta endeavours to base itself essentially on the facts of experience—in the fullest sense of the term. It recognizes the occurrence of everyday experience and the so-called fact of evil, but it refuses to view them as real. The real, it says, like Hegel, does not exist, and that which exists is not real. Evil is only an “existent"—as all this Samsara is—but not the ultimate Real. But it will be at once objected that if evil is an appearance, a (...) Maya, why should this appearance appear at all? If it has no foundation in reality, how and why does it occur at all? Further, how can anything be known as real unless it should appear ? Reality must appear. (shrink)

Chakravarthi Ram-Prasad offers illuminating new perspectives on contemporary phenomenological theories of body and subjectivity, based on studies of diverse classical Indian texts. He argues for a 'phenomenological ecology' of bodily subjectivity in health, gender, contemplation, and lovemaking.

Man is endowed with brain and mind for comprehending reality of the world. Brain is material entity and is observable, while mind is a non-physical conceived entity. Scientific investigations enhance our knowledge of the functioning of brain and its constituents. They indicate mind-brain association but do not rule out the possibility, in which mind is a property of brain. The perceived reality of the world has both objective and subjective components. The objective components are attributed to brain either alone or (...) in association with mind. The subjective components are considered to be the creations of mind but they appear to contain grains of reality. Attempts made to separate these grains have succeeded partially. One hopes for complete success only after the incorporation of a few missing ingredients. It is our contention that the missing ingredients are human being as an entangled quantum entity - photon field, quantum entity's capability to read information from photon fields of other humans and from its own field reflected by the environment. The evidence for the first ingredient is provided by the analysis of spontaneously emitted visible range photon signals by human beings. The other two ingredients put usual charge- photon interaction in proper context. The experimental results relevant to mind- brain interface are briefly described. A few minutes' time series of small portion of these signals determines their nine properties, which establish quantum nature of signal, and specify quantum state of the dominant component to be squeezed state. Six properties differ in signals emitted at 12 anatomical sites of the same person. Profile of a property for a person is the set of its values at 12 sites. Profile is very informative and can discriminate persons with differing holistic features. Cluster analysis offers procedures for measuring qualitative holistic features e.g. procedure for measuring ‘meditativeness' of a person. The incorporation of other two ingredients chalks out a route for answering the question who we are? (shrink)

This paper deals with issues related to character building and human values, both in personal and work life. The focus of the author is value-centred management, which has been discussed along two aspects of the human self, that is, the micro self and macro self. Here, the author tries to highlight the importance of both 'selves' in the organizational context. In the concluding part of the paper the author presents the authenticity of Kautilya's views on the macro self in the (...) context of the present business scenario. The author attempts to portray the transition created by the market economy, which cannot provide an exclusively painless solution. Moreover, he advocates culturing of self-discipline in corporate life, which can bring about qualitative improvement, both in work and personal life. 'Work with integrity and serve with love' is the philosophy the author presents in this paper. (shrink)

This article underscores the need for entrepreneurship research in extreme contexts to conceptualize the idiosyncrasies of the geopolitical dynamics under which entrepreneurs operate, and to consider the ethical implications emanating thereof. Undertaking such a task will illuminate the contextual challenges that local entrepreneurs must routinely placate, or otherwise navigate, to survive. Drawing on rich qualitative data from the Occupied Palestinian Territory of the West Bank, this paper demonstrates one avenue by which to capture the nuances of an extreme context in (...) relation to its effects on the entrepreneurial process. Specifically, it shows how data collected at myriad institutional sites—from actors that are not only directly, but also tangentially, connected to entrepreneurship in the local market—can effectively unveil the vicissitudes of the extreme context. This article further contends that a comprehensive and a holistic understanding of the extreme context will move toward revealing the nature of political embeddedness of entrepreneurs in their institutionally unstable environment—a concern that is especially conspicuous in geopolitical areas that would qualify as being extreme.

Drawing on a rich variety of Indian texts across multiple traditions, including Vedanta, Buddhist, Yoga and Jain, this collection explores how emotional experience is framed, evoked and theorized in order to offer compelling insights into human subjectivity. Rather than approaching emotion through the prism of Western theory, a team of leading Indian philosophers showcase the unique literary texture, philosophical reflections and theoretical paradigms that classical Indian sources provide in their own right. From solitude in the Saundarananda and psychosomatic theories of (...) disease in the Yogavasistha to female lament in Greek, Sinhala Buddhist and Sanskrit epic tales, their chapters reveal the range and diversity of the phenomena encompassing the English term 'emotion'. In doing so, they contribute towards a more cosmopolitan, comparative and pluralistic conception of human experience. Adopting a broad phenomenological methodology, this handbook reframes debates on emotion within classical Indian thought and is an invaluable resource for researchers and students seeking to understand the field beyond the Western tradition.

Thus one should define, in a double way, name and form in all phenomena of the three realms. …In this essay, we want to bring together two issues for their mutual illumination: the particular use of that hoary Indian dyad, "nāma-rūpa," literally, "name-and-form," by Buddhaghosa, the influential fifth-century Theravāda writer, to organize the categories of the abhidhamma, the canonical classification of phenomenal factors and their formulaic ordering;1 and an interpretation of phenomenology as a methodology. We argue that Buddhaghosa does not (...) use abhidhamma as a reductive ontological division of the human being into mind and body, but rather as the contemplative structuring of human phenomenology....

Reading a passage in the Sanskrit Mahābhārata—the attempted disrobing of Princess Draupadī after her senior husband has gambled her away (after losing all his wealth, his brothers and himself)—I suggest that we see in her attitude and angry words an expression of contempt. I explore how contempt is a concept that is not thematized within Sanskrit aesthetics of emotions, but nonetheless is clearly articulated in the literature. Focusing on the significance of her gendered expression of anger and contempt, and the (...) positive acceptance of it in the text, I suggest that contempt can be understood as a transformative attitude in a woman (even a high-born one) towards iniquities in a patriarchal culture.
