Crespi & Badcock (C&B) have presented a novel view that the influence of genomic imprinting causes diametrically opposite disorders: namely, psychoses and autism. I propose an extended hypothesis that while genomic imprinting is likely to have an influence on the pathogenesis of psychoses and autism, it might contribute to phenomenological antithesis between as well as within these disorders.

The role of various organizational pressures in influencing performance of firms has been an interesting research topic in a variety of fields and has received the attention of researchers working in the field of environmental strategy. Although there are previous studies that have looked at the influence of various pressures in influencing firms’ environmental strategies, our study provides a more holistic analysis considering a variety of such pressures in a single framework. We discuss a research study to analyze how pressures (...) from internal and external stakeholders of a firm, economic pressures, environmental regulations, and pressures of environmental compliance have affected environmental performance of firms using data collected from manufacturing firms in the United Kingdom. We have found that internal stakeholders provide the greatest impact in shaping environmental performance of firms, closely followed by economic pressures, environmental regulations, and external stakeholders in that order. Fears of penalties due to environmental compliance have the least impact, although this pressure also has a positive and significant impact on environmental performance. (shrink)

The order of discovery can have a profound effect upon the way in which we think about the function of a gene. In E. coli, recA is nearly essential for cell survival in the presence of DNA damage. However, recA was originally identified, as a gene required to obtain recombinant DNA molecules in conjugating bacteria. As a result, it has been frequently assumed that recA promotes the survival of bacteria containing DNA damage by recombination in which DNA strand exchanges occur. (...) We now know that several of the processes that interact with or are controlled by recA, such as excision repair and translesion synthesis, operate to ensure that DNA replication occurs processively without strand exchanges. Yet the view persists in the literature that recA functions primarily to promote recombination during DNA repair. With the benefit of hindsight and more than three decades of additional research, we reexamine some of the classical experiments that established the concept of DNA repair by recombination, and we consider the possibilities that recombination is not an efficient mechanism for rescuing damaged cells, and that recA may be important for maintaining processive replication in a manner that does not generally promote recombination.

This article identifies how democracy and transparency in Thailand have been subverted since 2001. Specifically, it appraises the sentiments and trends that have been in place since 1993 to prevent a return to authoritarian government. Additionally, it also examines structures and policies that have thwarted democratic consolidation since 2000. The central hypothesis of the article is that there has been a structural weakening of democracy in Thailand under the Thai Rak Thai government since 2001. In other words, Thailand's democratic consolidation (...) has been held in abeyance since the electoral victory of the Thaksin government. (shrink)

The bilateral relationship between China and Myanmar is important and intricate despite being asymmetrical in China's favour. Whereas most observers regard the relationship as being heavily weighted in China's favour, Myanmar does have a fair amount of latitude within the relationship that is informed by historical, economic, and strategic considerations. The nationalism and xenophobia present in the attitudes of elite from the Myanmar military junta is both recognized and understood by China that is keen to have a stable peripheral environment. (...) There are also important security issues such as the ethnic armies that currently have a ceasefire arrangement with the junta along the border areas that need to be resolved in a coordinated fashion to prevent negative spillage into China. In light of such special idiosyncratic and terrain considerations, Myanmar wields relative independence within this asymmetrical relationship. (shrink)

Commentary on the Mīmāṃsāsūtra of Jaimini, on Mimamsa philosophy.

This article examines Thai policy towards Malaysia and Myanmar in the post-Cold War period and argues that bilateral relations between Thailand and these countries have deteriorated considerably. The immediate reason for the change is the collapse of structural arrangements associated with the Cold War, in particular the Indochina Security Complex and domestic political developments in Thailand and Myanmar. Whereas a number of issues like illegal migration, fishing and insurgency have contributed to the deteriorated relations, the situation has been reasonably well (...) managed. Factors contributing to the stability of the situation include regular bilateral dialogue and exchanges as well as common membership in a number of multilateral fora like ASEAN, ARF, AFTA and APEC.

The September 2006 military coup against the Thaksin government in Thailand has had a profound impact on Thai politics. It has arrested the process of democratic consolidation that was set in motion in the country in the 1990s. Although many of Thaksin's policies lacked the spirit of democratic governance, he was democratically elected and was ousted from power unconstitutionally. The entire tenure of Thaksin has brought to the fore two deep cleavages in Thailand. The first of these is the deep (...) divide between the rural and urban electoral constituencies. The former provided a major vote bank with little bearing on the dispersion of power and resources that was effectively dominated by the latter. Thaksin and his populist policies effectively undermined the urban electorate and strengthened the rural constituency. The second and perhaps structurally more significant tension is that which has developed between the new business elite and the old establishment elite that comprise the monarchy, military, and the bureaucracy. This old elite has been at the forefront of displacing Thaksin through its fear of loss of control over the domestic political process. The drawn out confrontation that has spawned two social movements has significantly raised the country's political temperature and there is the real potential for the situation to deteriorate into violence. Despite these changes, a number of continuities unique to the Thai political situation continue to obtain as well. (shrink)

This volume, an important contribution to dialogic and Bakhtin studies, shows the natural fit between Bakhtin’s ideas and the pluralistic culture of India to a global academic audience. It is premised on the fact that long before principles of dialogism took shape in the Western world, these ideas, though not labelled as such, were an integral part of intellectual histories in India. Bakhtin’s ideas and intellectual traditions of India stand under the same banner of plurality, open-endedness and diversity of languages (...) and social speech types and, therefore, the affinity between the thinker and the culture seems natural. Rather than being a mechanical import of Bakhtin’s ideas, it is an occasion to reclaim, reactivate and reenergize inherent dialogicality in the Indian cultural, historical and philosophical histories. Bakhtin is not an incidental figure, for he offers precise analytical tools to make sense of the incredibly complex differences at every level in the cultural life of India. Indian heterodoxy lends well to a Bakhtinian reading and analysis and the papers herein attest to this. The papers range from how ideas from Indo-European philology reached Bakhtin through a circuitous route, to responses to Bakhtin’s thought on the carnival from the philosophical perspectives of Abhinavagupta, to a Bakhtinian reading of literary texts from India. The volume also includes an essay on ‘translation as dialogue’ – an issue central to multilingual cultures – and on inherent dialogicality in the long intellectual traditions in India. (shrink)

Automatic Generation Control in modern power systems is getting complex, due to intermittency in the output power of multiple sources along with considerable digressions in the loads and system parameters. To address this problem, this paper proposes an approach to calculate Power System Restoration Indices of a 2-area thermal-hydro restructured power system. This study also highlights the necessary ancillary service requirements for the system under a deregulated environment to cater to large-scale power failures and entire system outages. An abrupt change (...) in consumer load demands and disturbances in any control region of a multiarea system causes severe fluctuations in frequency and interarea power exchanges. However, simple Proportional and Integral controllers are most prevalent in the literature to effectively resolve AGC issues, while its integral gain is smaller due to the larger overshoot in transient performance. Therefore, an attempt has been made with a novel control strategy, known as the pseudoderivative feedforward with feedback controller, is developed to keep the interarea power exchanges and the frequency to the specified limits after load changes. A PDFF controller is designed and implemented using the flower pollination algorithm to obtain optimal dynamic performance for different types of potential power flows in a restructured power system under investigation. The proposed PDFF controller localizes the zero at an optimal place that reduces the rise time of the step-response to reduce the excessive overshoot and gives much better dynamic performances as compared to the PI control structure. The Integral Square Error is considered as a performance criterion to derive the optimized gain of the PDFF control structure using FPA. Different PSRI are computed based on the transient response of the 2-area deregulated multisource system and different restoration measures to be taken are also discussed. The simulation results clearly show that the proposed approach is very powerful in decreasing the frequency and tie-power digressions under different load perturbations. (shrink)

Derek Parfit, who died in 2017, is widely believed to have been the best moral philosopher in well over a century. The twenty new essays in this book were written in his honour and have all been inspired by his work - in particular, his work in an area of moral philosophy known as 'population ethics', which is concerned with moral issues raised by causing people to exist. Until Parfit began writing about these issues in the 1970s, there was almost (...) no discussion of them in the entire history of philosophy. But his monumental book 'Reasons and Persons' (1984) revealed that population ethics abounds in deep and intractable problems and paradoxes that not only challenge all the major moral theories but also threaten to undermine many important common-sense moral beliefs.

Many targets of the Wnt/β-catenin signaling pathway are regulated by TCF transcription factors, which play important roles in animal development, stem cell biology, and oncogenesis. TCFs can regulate Wnt targets through a “transcriptional switch,” repressing gene expression in unstimulated cells and promoting transcription upon Wnt signaling. However, it is not clear whether this switch mechanism is a general feature of Wnt gene regulation or limited to a subset of Wnt targets. Co-repressors of the TLE family are known to contribute to (...) the repression of Wnt targets in the absence of signaling, but how they are inactivated or displaced by Wnt signaling is poorly understood. In this mini-review, we discuss several recent reports that address the prevalence and molecular mechanisms of the Wnt transcription switch, including the finding of Wnt-dependent ubiquitination/inactivation of TLEs. Together, these findings highlight the growing complexity of the regulation of gene expression by the Wnt pathway. Wnt targets are regulated by a “switch” where TLE co-repressors are displaced from TCFs by β-catenin, leading to activation of transcription. Recent reports challenge this view and suggest that additional processes, including exchange of specific TCF proteins and Wnt-dependent ubiquitination of TLEs, play important roles in the Wnt transcriptional switch.

Niranjan Ramakrishnan examines the surprising extent to which Gandhi's writings still provide insight into current global tensions and the assumptions that drive them. This book explores how ideas Gandhi expressed over a century ago can be applied today to issues from terrorism to the environment, globalization to the 'Clash of Civilizations.' In particular it looks at Gandhi's emphasis on the small, the local, and the human – an emphasis that today begins to appear practical, attractive, and even inescapable. Written (...) in an accessible style invoking examples from everyday happenings familiar to all, this concise volume reintroduces Gandhi to today's audiences in relevant terms. (shrink)

To understand the variations in the financial characteristics, we examine the dynamical behaviors by considering the chaotic financial model with external force. First, the dynamical characteristics are analyzed by introducing the external driven force in the price index with commodity demand. We discover that the presence of an external force causes the alternate occurrence of oscillatory and steady states as a function of time. Interestingly, we find the existence of bifurcation delay during the transition from oscillatory to steady state or (...) vice versa. Bifurcation delay is a phenomenon in which the bifurcation does not occur at the actual bifurcation point but rather at a later time, which is referred to as bifurcation delay. To confirm the delay in bifurcation, we estimate the actual bifurcation point and compare it to the observed bifurcation transition. Furthermore, to understand the variations in the bifurcation delay, we estimate the delay time between each consecutive cycle and find random fluctuations in the BD. Following that, the BD is virtualized via a transformed phase portrait. In addition, we show decreasing the value of average BD while increasing the frequency of external forcing. Second, the presence of BD is explored by incorporating external forces into the investment demand with unit investment cost. We discover the existence of a similar phenomenon with a constant bifurcation delay. (shrink)

A proper elementary extension of a model is called small if it realizes no new types over any finite set in the base model. We answer a question of Marker, and show that it is possible to have an o-minimal structure with a maximal small extension. Our construction yields such a structure for any cardinality. We show that in some cases, notably when the base structure is countable, the maximal small extension has maximal possible cardinality.

Dynamical analysis, chaos suppression and electronic implementation of the synchronous reluctance motor without external inputs are investigated in this paper. The different dynamical behaviors found in the SynRM without external inputs are illustrated in the two parameters largest Lyapunov exponent diagrams, one parameter bifurcation diagram, and phase portraits. The three single controllers are designed to suppress the chaotic behaviors found in SynRM without external inputs. The three proposed single controllers are simple and easy to implement. Numerical simulation results show that (...) the three proposed single controllers are effective. Finally, the dynamical behaviors found in the SynRM without external inputs and the physical feasibility of the three proposed single controllers are validated through circuit implementation on OrCAD-PSpice software.

We prove that a function definable with parameters in an o-minimal structure is bounded away from ∞ as its argument goes to ∞ by a function definable without parameters, and that this new function can be chosen independently of the parameters in the original function. This generalizes a result in [1]. Moreover, this remains true if the argument is taken to approach any element of the structure , and the function has limit any element of the structure.

The nature of the relationship between environmental performance and firm performance of corporations is a long standing and contentious issue in the literature. This study is intended to advance this debate by arguing for the existence of curvilinear relationship and empirically testing the same using survey data on UK manufacturing firms. FP is captured in terms of growth in sales and market share. Our results show evidence for a quadratic relationship—as firms improve their EP, they seem to achieve much higher (...) levels of FP. These results are consistent with the resource-based view of a firm; as firms engage in EP activities, they are able to gain inimitable knowledge that helps in further learning to further improve performance. Based on our results, we suggest that new studies focus on strategies to extend the period of increasing returns and maximizing the benefits of the positive association between EP and FP. (shrink)

The Homeobox (Hox) genes essentially define body regions in all animals including humans – responsible for determining two arms, two legs, one nose and so on. This gene is shared by all living beings – from the snail to the elephant to humans – and it can now be manipulated into transforming certain parts of the body into others. We have observed such transformations, such as that of an amputated antenna into a limb, as far back as 1901, termed neomorphosis (...) (Morgan 1901), and it has only recently re-emerged as an area of scientific study. Spontaneous transformations and induced regenerations are fascinating research topics that are fast becoming a reality; some scientists are postulating that it may be possible that the hox gene could be central to limb regeneration in the future. This article will present the Hox Zodiac project, which attempts to introduce this subject and push the ideas further into speculation of mutation (i.e. humans and animals) into creatures that may resemble the mythical beings we know as fiction. The starting point of this wheel of life is the Chinese zodiac, consisting of twelve animals that are associated with humans. In the process of development, it became interesting to note that half of the animals on the wheel are those used in the lab – rat, pig, monkey, dog, sheep and rabbit. The ox, tiger, horse, snake and rooster are considered mythical and the dragon could easily fall into the category of a genetically modified creature that is to re-emerge in the future. Since medical and scientific testing on humans is strictly forbidden, scientists have virtually shifted to animals for all such studies. Thus, everything that is used on our bodies and minds is directly related to the animal kingdom. The pig heart and rat mind are symbols for the paradox of science that uses animals in ways that are at once disconnected while subconsciously connecting us more than ever by using research results in medical and food products we consume. Although the controversy of using animals in labs is widely known and often violently opposed, the artist in the lab questions how this research impacts our collective consciousness, especially with the growing trend of brain-computer interfaces and particularly synthetic telepathy. This relationship of the human to the metaphorical meaning of the animal kingdom brought to mind Jung’s research on metaphors, symbolism and archetypes, which became central to the Hox Zodiac.

We prove that in an arbitrary o-minimal structure, every interpretable group is definably isomorphic to a definable one. We also prove that every definable group lives in a cartesian product of one-dimensional definable group-intervals. We discuss the general open question of elimination of imaginaries in an o-minimal structure.

BackgroundConventionally, transcranial direct current stimulation (tDCS) aims to focalize the current reaching the target region-of-interest (ROI). The focality can be quantified by the dose-target-determination-index (DTDI). Despite having a uniform tDCS setup, some individuals receive focal stimulation (high DTDI) while others show reduced focality (“non-focal”). The volume of cerebrospinal fluid (CSF), gray matter (GM), and white matter (WM) underlying each ROI govern the tDCS current distribution inside the brain, thereby regulating focality.AimTo determine the regional volume parameters that differentiate the focal and (...) non-focal groups.MethodsT1-weighted images of the brain from 300 age-sex matched adults were divided into three equal groups- (a) Young (20 ≤ × < 40 years), (b) Middle (40 ≤ × < 60 years), and (c) Older (60 ≤ × < 80 years). For each group, inter and intra-hemispheric montages with electrodes at (1) F3 and right supraorbital region (F3-RSO), and (2) CP5 and Cz (CP5-Cz) were simulated, targeting the left- Dorsolateral Prefrontal Cortex (DLPFC) and -Inferior Parietal Lobule (IPL), respectively. Both montages were simulated for two current doses (1 and 2 mA). For each individual head simulated for a tDCS configuration (montage and dose), the current density at each region-of-interest (ROI) and their DTDI were calculated. The individuals were categorized into two groups- (1) Focal (DTDI ≥ 0.75), and (2) Non-focal (DTDI < 0.75). The regional volume of CSF, GM, and WM of all the ROIs was determined. For each tDCS configuration and ROI, three 3-way analysis of variance was performed considering- (i) GM, (ii) WM, and (iii) CSF as the dependent variable (DV). The age group, sex, and focality group were the between-subject factors. For a given ROI, if any of the 3 DV’s showed a significant main effect or interaction involving the focality group, then that ROI was classified as a “focal ROI.”ResultsRegional CSF was the principal determinant of focality. For interhemispheric F3-RSO montage, interaction effect (p < 0.05) of age and focality was observed at Left Caudate Nucleus, with the focal group exhibiting higher CSF volume. The CSF volume of focal ROI correlated positively (r ∼ 0.16, p < 0.05) with the current density at the target ROI (DLPFC). For intrahemispheric CP5-Cz montage, a significant (p < 0.05) main effect was observed at the left pre- and post-central gyrus, with the focal group showing lower CSF volume. The CSF volume correlated negatively (r ∼ –0.16, p < 0.05) with current density at left IPL. The results were consistent for both current doses.ConclusionThe CSF channels the flow of tDCS current between electrodes with focal ROIs acting like reservoirs of current. The position of focal ROI in the channel determines the stimulation intensity at the target ROI. For focal stimulation in interhemispheric F3-RSO, the proximity of focal ROI reserves the current density at the target ROI (DLPFC). In contrast, for intrahemispheric montage (CP5-Cz), the far-end location of focal ROI reduces the current density at the target (IPL). (shrink)

IntroductionIn highly developed countries, as many as 16 percent of children are physically abused each year. Traumatic brain injury (TBI) is the most common injury in non-accidental trauma (NAT) and is responsible for 80 percent of fatal NAT cases, with most deaths occurring in children younger than three years old. Cases of abusers who refuse withdrawal of life-sustaining medical treatment (LSMT) to avoid criminal charges have previously been reported. Therefore, we hypothesized that NAT is associated with a lower risk for (...) withdrawal LSMT in pediatric TBI.MethodsThe pediatric Trauma Quality Improvement Program database was analyzed (2014 to 2016) for patients aged 16 and younger with TBI and Glasgow Coma Scale (GCS) of 8 and lower on admission. Patients with a head Abbreviated Injury Scale (AIS) of 2 or less or who died within 48 hours were excluded. A multivariable logistic regression model was used for analysis.ResultsOf 2,209 TBI patients, 92 (4.2 percent) had withdrawal of LSMT. Compared to those without withdrawal of LMST, those with LMST had statistically similar median age (three years of age versus seven years, p = 0.07) and a higher rate of NAT (33.7 percent versus 13.5 percent, p < 0.001). The most common specified perpetrator was a father/stepfather/ male partner (70 percent). After adjusting for covariates, factors associated with higher risk for withdrawal of LSMT included age of less than three years (OR 2.38, CI 1.34-4.23, p < 0.05) and NAT (OR 1.86, CI 1.02-3.41, p < 0.05).ConclusionNAT is associated with increased risk for withdrawal of LSMT in pediatric TBI. Age of less than three years is similarly associated with a higher risk for withdrawal of LSMT. Future research in this population is needed to determine what other factors predict withdrawal of LSMT and what resources, such as social workers and/or ethics consults, are utilized. (shrink)

AimsIn this pilot mixed-methods study, we examined the participants experiences of engaging in virtual drawing tasks and the impact of an olfactory stimulus on outcomes of affect, stress, self-efficacy, anxiety, creative agency, and well-being.MethodsThis study used a parallel mixed-methods, simple block randomization design. The study participants included 24 healthy adults aged 18 to 54 years, including 18 women and six men. The participants completed two 1-h immersive virtual art making sessions and were randomly assigned to receive either a fragrance or (...) a non-fragrance condition for the first session. Quantitative and qualitative datasets were collected concurrently and integrated during data analysis.ResultsThe quantitative results indicated that the fragrance condition demonstrated a significant reduction in negative affect, namely, reduced feelings of negativity when compared to the non-fragrance condition. A trend toward improvement in self-efficacy was also seen in the fragrance condition. No significant changes were found for fragrance or non-fragrance conditions for positive affect, anxiety, and creative agency. The qualitative findings included five themes related to art making experiences in virtual reality in both conditions: fun and joy; novelty of virtual media, experimentation, and play; relaxation and calm; learning curve; and physical discomfort and disorientation. Four themes were identified for virtual art content and visual qualities: nature imagery, references to memories and personal symbols, fantasy and play within imagery, and depiction of everyday objects.ConclusionsOverall, the participants reported positive responses to the novel virtual art making experiences which were further heightened by the inclusion of the fragrance stimulus for negative affect. These preliminary findings need to be replicated with larger sample sizes to confirm the outcomes and the trends that were seen in this pilot study. Further research is recommended to examine the differences between experiences of virtual and traditional art media and to examine different olfactory stimuli promoting focus and concentration.

Background: Ethical frameworks for organ donation following circulatory death (DCD) were established >20 years ago. However, considerable variation exists among these, indicating consensus has not been reached on all issues. Additionally, advances such as cardiac DCD transplants and normothermic regional perfusion (NRP) may have reignited old debates.Methods: We reviewed the English-language literature addressing ethical issues in DCD from 1993 to 2022, examining changes in frequency with which ethical principles and their sub-themes identified within each, were addressed.Results: Non-maleficence was the most (...) frequently addressed principle (192 of 199 articles), as well as the most varied, with 9 subthemes (versus 2-4 within each of the other bioethical principles).Conclusions: There were several changes in the terminology used to refer to DCD over time, and substantial interest in cardiac DCD and NRP in recent publications, arising in 11 and 19 of the 30 publications from 2018 to 2022.

In this paper, we propose a new and simple method for image encryption. It uses an external secret key of 128 bits long and an internal secret key. The novelties of the proposed encryption process are the methods used to extract an internal key to apply the zigzag process, affine transformation, and substitution-diffusion process. Initially, an original gray-scale image is converted into binary images. An internal secret key is extracted from binary images. The two keys are combined to compute the (...) substitution-diffusion keys. The zigzag process is firstly applied on each binary image. Using an external key, every zigzag binary image is reflected or rotated and a new gray-scale image is reconstructed. The new image is divided into many nonoverlapping subblocks, and each subblock uses its own key to take out a substitution-diffusion process. We tested our algorithms on many biomedical and nonmedical images. It is seen from evaluation metrics that the proposed image encryption scheme provides good statistical and diffusion properties and can resist many kinds of attacks. It is an efficient and secure scheme for real-time encryption and transmission of biomedical images in telemedicine. (shrink)

This paper explores the “triangulation approach” in social science research methods. Triangulation is an emerging method specifically in qualitative and multi-method studies. Researchers in the social sciences have increased their use of the triangulation approach recently due to the merits of this approach, especially to conduct in-depth studies through multiple inquiries. Simultaneously, this method has criticism and misconceptions among social researchers in terms of what it is, how it can be used, and the credibility of the findings when used. Therefore, (...) this paper analyses in depth what triangulation is, the types of triangulations and how they can be applied in the social sciences. The study basically adopted systematic literature review and used 30 articles published in scientific journals. The paper critically reviewed journal articles related to triangulation, revealed how different types of triangulation methods have been applied in the social sciences and highlighted the merits and cautions of applying this method. The paper theoretically contributes to understanding the phenomenon of the triangulation approach and how it connects with qualitative and multi-method studies. In addition, it revealed that the following data collection techniques from multiple sources can be exploited: in-depth interviews, focus group discussions, literature, documents, and surveys on the triangulation method to improve the credibility and reliability of the research. Furthermore, the study empirically contributes to social science researchers applying this approach with proper understanding. (shrink)

Studies on Neurospora chromosome segment duplications (Dps) performed since the publication of Perkins's comprehensive review in 1997 form the focus of this article. We present a brief summary of Perkins's seminal work on chromosome rearrangements, specifically, the identification of insertional and quasiterminal translocations that can segregate Dp progeny when crossed with normal sequence strains (i.e., T × N). We describe the genome defense process called meiotic silencing by unpaired DNA that renders Dp‐heterozygous crosses (i.e., Dp × N) barren, which provides (...) a basis for identifying Dps, and discuss whether other processes also might contribute to the barren phenotype of Dp × N and Dp × Dp crosses. We then turn to studies suggesting that large Dps (i.e., >300 kbp) can allow smaller gene‐sized duplications to escape another genome defense process called repeat‐induced point mutation (RIP), possibly by titration of the RIP machinery. Finally, we assess whether in natural populations dominant RIP suppressor Dps provide an “RIP‐free” niche for evolution of new genes following the duplication of existing genes. (shrink)
