One of the most compelling questions still unanswered in neuroscience is how consciousness arises. In this article, we examine visual processing, the parietal lobe, and contralateral neglect syndrome as a window into consciousness and how the brain functions as the mind and we introduce a mechanism for the processing of visual information and its role in consciousness. We propose that consciousness arises from integration of information from throughout the body and brain by the thalamus and that the thalamus reimages visual (...) and other sensory information from throughout the cortex in a default three-dimensional space in the mind. We further suggest that the thalamus generates a dynamic default three-dimensional space by integrating processed information from corticothalamic feedback loops, creating an infrastructure that may form the basis of our consciousness. Further experimental evidence is needed to examine and support this hypothesis, the role of the thalamus, and to further elucidate the mechanism of consciousness. (shrink)

The Global Workspace Theory and Information Integration Theory are two of the most currently accepted consciousness models; however, these models do not address many aspects of conscious experience. We compare these models to our previously proposed consciousness model in which the thalamus fills-in processed sensory information from corticothalamic feedback loops within a proposed 3D default space, resulting in the recreation of the internal and external worlds within the mind. This 3D default space is composed of all cells of the body, (...) which communicate via gap junctions and electrical potentials to create this unified space. We use 3D llustrations to explain how both visual and non-visual sensory information may be filled-in within this dynamic space, creating a unified seamless conscious experience. This neural sensory memory space is likely generated by baseline neural oscillatory activity from the default mode network, other salient networks, brainstem, and reticular activating system.

The complex activity of the human brain makes it difficult to get a big picture of how the brain works and functions as the mind. We examine pertinent studies, as well as evolutionary and embryologic evidence to support our theoretical model consisting of separate but interactive layers of human neural activity. The most basic layer involves default mode network (DMN)activity and cardiorespiratory oscillations. We propose that these oscillations support other neural activity and cognitive processes. The second layer involves limbic system (...) activity accompanied by corresponding changes in cardiorespiratory oscillations. The third layer consists of corticothalamic processing and involves higher cortical functions including awareness, cognition,and consciousness. These layers interact to form the complex neural activity of the human brain. Examining the origins and relationships of various neural and physiologic oscillations may provide better understanding of human neurophysiology and consciousness. (shrink)

Understanding the autonomic nervous system and homeostatic changes associated with emotions remains a major challenge for neuroscientists and a fundamental prerequisite to treat anxiety, stress, and emotional disorders. Based on recent publications, the inter-relationship between respiration and emotions and the influence of respiration on autonomic changes, and subsequent widespread membrane potential changes resulting from changes in homeostasis are discussed. We hypothesize that reversing homeostatic alterations with meditation and breathing techniques rather than targeting neurotransmitters with medication may be a superior method (...) to address the whole body changes that occur in stress, anxiety, and depression. Detrimental effects of stress, negative emotions, and sympathetic dominance of the autonomic nervous system have been shown to be counteracted by different forms of meditation, relaxation, and breathing techniques. We propose that these breathing techniques could be used as firstline and supplemental treatments for stress, anxiety, depression, and some emotional disorders. (shrink)

Pranayamic breathing, defined as a manipulation of breath movement, has been shown to contribute to a physiologic response characterized by the presence of decreased oxygen consumption, decreased heart rate, and decreased blood pressure, as well as increased theta wave amplitude in EEG recordings, increased parasympathetic activity accompanied by the experience of alertness and reinvigoration. The mechanism of how pranayamic breathing interacts with the nervous system affecting metabolism and autonomic functions remains to be clearly understood. It is our hypothesis that voluntary (...) slow deep breathing functionally resets the autonomic nervous system through stretchinduced inhibitory signals and hyperpolarization currents propagated through both neural and non-neural tissue which synchronizes neural elements in the heart, lungs, limbic system and cortex. During inspiration, stretching of lung tissue produces inhibitory signals by action of slowly adapting stretch receptors (SARs) and hyperpolarization current by action of fibroblasts. Both inhibitory impulses and hyperpolarization current are known to synchronize neural elements leading to the modulation of the nervous system and decreased metabolic activity indicative of the parasympathetic state. In this paper we propose pranayama’s physiologic mechanism through a cellular and systems level perspective,involving both neural and non-neural elements. This theoretical description describes a common physiological mechanism underlying pranayama and elucidate the role of the respiratory and cardiovascular system on modulating the autonomic nervous system. Along with facilitating the design of clinical breathing techniques for the treatment of autonomic nervous system and other disorders, this model will also validate pranayama as a topic requiring more research.

Stress profoundly impacts quality of life and may lead to various diseases and conditions. Understanding the underlying physiological and neurological processes that take place during stress and meditation techniques may be critical for effectively treating stress-related diseases. The article examines a hypothetical physiological homeostatic response that compares and contrasts changes in central and peripheral oscillations during stress and meditation, and relates these to changes in the autonomic system and neurological activity. The authors discuss how cardiorespiratory synchronization, which occurs during the (...) parasympathetic response and meditation, influences and modulates activity and oscillations of the brain and autonomic nervous system. Evidence is presented on how synchronization of cardiac and respiratory rates during meditation may lead to a homeostatic increase in cellular membrane potentials in neurons and other cells throughout the body. These potential membrane changes may underlie the reduced activity in the amygdala, and other cortical areas during meditation, and research examining these changes may foster better understanding of the restorative properties and health benefits of meditation.

High blood pressure is an important component of pre-eclampsia. The underlying mechanism of development of hypertension in pre-eclampsia is complicated and still remains obscure. Several theories have been advanced including endothelial dysfunction, uteroplacental insufficiency leading to generalized vasoconstriction, increased cardiac output, and sympathetic hyperactivity. Increased blood flow and pressure are thought to lead to capillary dilatation, which damages end-organ sites, leading to hypertension, proteinuria and edema. Additional theories have been put forward based on epidemiological research, implicating immunological and genetic factors. (...) None of these theories have been substantiated. Based on a review of literature this paper postulates that the initiating event for the development of preeclampsia is intermittent hypoxia associated with irregular breathing during sleep, hypoapnea, apnea,inadequate respiratory excursions during the waking hours and inadequate cardiopulmonary synchronization (abnormal sympatho-vagal balance).

The human eyes and brain, which have finite boundaries, create a ‘‘virtual’’ space within our central nervous system that interprets and perceives a space that appears boundless and infinite. Using insights from studies on the visual system, we propose a novel fast processing mechanism involving the eyes, visual pathways, and cortex where external vision is imperceptibly processed in our brain in real time creating an internal representation of external space that appears as an external view. We introduce the existence of (...) a three-dimension default space consisting of intrapersonal body space that serves as the framework where visual and non-visual sensory information is sensed and experienced. We propose that the thalamus integrates processed information from corticothalamic feedback loops and fills-in the neural component of 3D default space with an internal visual representation of external space, leading to the experience of visual consciousness. This visual space inherently evades perception so we have introduced three easy clinical tests that can assist in experiencing this visual space. We also review visual neuroanatomical pathways, binocular vision, neurological disorders, and visual phenomenon to elucidate how the representation of external visible space is recreated within the mind.

Recent fndings illustrate how changes in consciousness accommodated by neural correlates and plasticity of the brain advance a model of perceptual change as a function of meditative practice. During the mindbody response neural correlates of changing awareness illustrate how the autonomic nervous system shifts from a sympathetic dominant to a parasympathetic dominant state. Expansion of awareness during the practice of meditation techniques can be linked to the Default Mode Network (DMN), a network of brain regions that is active when the (...) one is not focused on the outside world and the brain is restful yet awake (Chen et al., 2008). A model is presented illustrating the dynamic mindbody response before and after mindfulness meditation, and connections are made with prefrontal cortex activity, the cardiac and respiratory center, the thalamus and amygdala, the DMN and cortical function connectivity. The default status of the DMN changes corresponding to autonomic modulation resulting from meditation practice. (shrink)

Respiration influences various pacemakers and rhythms of the body during inspiration and expiration but the underlying mechanisms are relatively unknown. Understanding this phenomenon is important, as breathing disorders, breath holding, and hyperventilation can lead to significant medical conditions. We discuss the physiological modulation of heart rhythm, blood pressure, sympathetic nerve activity, EEG, and other changes observed during inspiration and expiration. We also correlate the intracellular mitochondrial respiratory metabolic processes with real-time breathing and correlate membrane potential changes with inspiration and expiration. (...) We propose that widespread minor hyperpolarization occurs during inspiration and widespread minor depolarization occurs during expiration. This depolarization is likely a source of respiratory drive. Further knowledge of intracellular and extracellular ionic changes associated with respiration will enhance our understanding of respiration and its role as a modulator of cellular membrane potential. This could expand treatment options for a wide range of health conditions, such as breathing disorders, stress-related disorders, and further our understanding of the Hering–Breuer reflex and respiratory sinus arrhythmia.

The role of the physiological processes involved in human vision escapes clarification in current literature. Many unanswered questions about vision include: 1) whether there is more to lateral inhibition than previously proposed, 2) the role of the discs in rods and cones, 3) how inverted images on the retina are converted to erect images for visual perception, 4) what portion of the image formed on the retina is actually processed in the brain, 5) the reason we have an after-image with (...) antagonistic colors, and 6) how we remember space. This theoretical article attempts to clarify some of the physiological processes involved with human vision. The global integration of visual information is conceptual; therefore, we include illustrations to present our theory. Universally, the eyeball is 2.4 cm and works together with membrane potential, correspondingly representing the retinal layers,photoreceptors, and cortex. Images formed within the photoreceptors must first be converted into chemical signals on the photoreceptors’ individual discs and the signals at each disc are transduced from light photons into electrical signals. We contend that the discs code the electrical signals into accurate distances and are shown in our figures. The pre-existing oscillations among the various cortices including the striate and parietal cortex,and the retina work in unison to create an infrastructure of visual space that functionally ‘‘places” the objects within this ‘‘neural” space. The horizontal layers integrate all discs accurately to create a retina that is pre-coded for distance. Our theory suggests image inversion never takes place on the retina,but rather images fall onto the retina as compressed and coiled, then amplified through lateral inhibition through intensification and amplification on the OFF-center cones. The intensified and amplified images are decompressed and expanded in the brain, which become the images we perceive as external vision. (shrink)

In this article, we examine phantom limb syndrome to gain insights into how the brain functions as the mind and how consciousness arises. We further explore our previously proposed consciousness model in which consciousness and body schema arise when information from throughout the body is processed by corticothalamic feedback loops and integrated by the thalamus. The parietal lobe spatially maps visual and non-visual information and the thalamus integrates and recreates this processed sensory information within a three-dimensional space termed the ‘‘3D (...) default space.’’ We propose that phantom limb syndrome and phantom limb pain arise when the afferent signaling from the amputated limb is lost but the neural circuits remain intact. In addition, integration of conflicting sensory information within the default 3D space and the loss of inhibitory afferent feedback to efferent motor activity from the amputated limb may underlie phantom limb pain.

Mind-body therapies have been shown to be effective in clinical treatment of disorders such as high blood pressure and stress. Significant differences in the effectiveness of mind–body therapies have been shown and a common link among the therapies has yet to be defined. This article overviews the role of slow rhythmic breathing in physiological as well as therapeutic effects of mind-body therapies. Slow deep breathing practice has important implications as it may underlie the basic mechanism that synchronizes the brain with (...) the autonomic response. This article reviews studies that include the effect of deep slow breathing with or without mind-body therapy exercises. In utero studies that monitor patterns of fetal breathing reveal sympathetic activation with irregular, shallow fast breathing movements compared to slow deep breathing. Recognition of respiratory mechanisms in mind-body therapies can lead to development of more effective relaxation exercises that may incorporate deep slow breathing in clinical applications.

Understanding the mechanics of consciousness remains one of the most important challenges in modern cognitive science. One key step toward understanding consciousness is to associate unconscious physiological processes with subjective experiences of sensory, motor, and emotional contents. This article explores the role of various cellular membrane potential differences and how they give rise to the dynamic infrastructure of conscious experience. This article explains that consciousness is a body-wide, biological process not limited to individual organs because the mind and body are (...) unified as one entity; therefore, no single location of consciousness can be pinpointed. Consciousness exists throughout the entire body, and unified consciousness is experienced and maintained through dynamic repolarization during inhalation and expiration. Extant knowledge is reviewed to provide insight into how differences in cellular membrane potential play a vital role in the triggering of neural and non-neural oscillations. The role of dynamic cellular membrane potentials in the activity of the central nervous system, peripheral nervous system, cardiorespiratory system, and various other tissues (such as muscles and sensory organs) in the physiology of consciousness is also explored. Inspiration and expiration are accompanied by oscillating membrane potentials throughout all cells and play a vital role in subconscious human perception of feelings and states of mind. In addition, the role of the brainstem, hypothalamus, and complete nervous system (central, peripheral, and autonomic)within the mind-body space combine to allow consciousness to emerge and to come alive. This concept departs from the notion that the brain is the only organ that gives rise to consciousness. (shrink)

The brain is considered to be the primary generator and regulator of emotions; however, afferent signals originating throughout the body are detected by the autonomic nervous system (ANS) and brainstem, and, in turn, can modulate emotional processes. During stress and negative emotional states, levels of cardiorespiratory coherence (CRC) decrease, and a shift occurs toward sympathetic dominance. In contrast, CRC levels increase during more positive emotional states, and a shift occurs toward parasympathetic dominance. Te dynamic changes in CRC that accompany different (...) emotions can provide insights into how the activity of the limbic system and afferent feedback manifest as emotions. The authors propose that the brainstem and CRC are involved in important feedback mechanisms that modulate emotions and higher cortical areas. That mechanism may be one of many mechanisms that underlie the physiological and neurological changes that are experienced during pranayama and meditation and may support the use of those techniques to treat various mood disorders and reduce stress.

Our experiences with the external world are possible mainly through vision, hearing, taste, touch, and smell providing us a sense of reality. How the brain is able to seamlessly integrate stimuli from our external and internal world into our sense of reality has yet to be adequately explained in the literature. We have previously proposed a three-dimensional unified model of consciousness that partly explains the dynamic mechanism. Here we further expand our model and include illustrations to provide a better conception (...) of the ill-defined space within the self, providing insight into a unified mind-body concept. In this article, we propose that our senses “super-impose” on an existing dynamic space within us after a slight, imperceptible delay. The existing space includes the entire intrapersonal space and can also be called the “the body’s internal 3D default space”. We provide examples from meditation experiences to help explain how the sense of ‘self’ can be experienced through meditation practice associated with underlying physiological processes that take place through cardio-respiratory synchronization and coherence that is developed among areas of the brain. Meditation practice can help keep the body in a parasympathetic dominant state during meditation, allowing an experience of inner ‘self’. Understanding this physical and functional space could help unlock the mysteries of the function of memory and cognition, allowing clinicians to better recognize and treat disorders of the mind by recommending proven techniques to reduce stress as an adjunct to medication treatment.

Current research on the various forms of autoscopic phenomena addresses the clinical and neurological correlates of out-of-body experiences, autoscopic hallucinations,and heautoscopy. Yet most of this research is based on functional magnetic resonance imaging results and focuses predominantly on abnormal cortical activity. Previously we proposed that visual consciousness resulted from the dynamic retinogeniculo-cortical oscillations, such that the photoreceptors dynamically integrated with visual and other vision-associated cortices, and was theorized to be mapped out by photoreceptor discs and rich retinal networks which synchronized (...) with the retinotopic mapping and the associated cortex. The feedback from neural input that is received from the thalamus and cortex via retinogeniculo-cortical oscillations and sent to the retina is multifold higher than feed-forward input to the cortex. This can effectively translate into out-of-body experiences projected onto the screen formed by the retina as it is perceived via feedback and feed-forward oscillations from the reticular thalamic nucleus, or “internal searchlight”. This article explores the role of the reticular thalamic nucleus and the retinogeniculo-cortical oscillations as pivotal internal components in vision and various autoscopic phenomena. (shrink)

Located within the ascending reticular activating system are nuclei which release neurotransmitters such as acetylcholine, serotonin, dopamine, and norepinephrine. These nuclei have widespread projections that extend into the limbic system and throughout cortex. Activation of these neurotransmitters during awake states leads to arousal, while inhibition leads to the loss of consciousness experienced during slow-wave sleep. Previously, we proposed a mechanism in which cardiorespiratory synchronization may underlie the widespread hyperpolarization that occurs throughout the brain during slow-wave sleep. We further propose that (...) a similar homeostatic mechanism may be involved in sleep-wake transitions and maintaining various arousal states including rapid eye movement sleep, waking, and anxiety. Widespread depolarization associated with more rapid, shallow breathing and desynchronized cardiorespiratory oscillatory activity may underlie waking, anxiety, and rapid eye movement sleep states. The exact voltage values of these widespread membrane potential changes remain unknown and possibly highly variable between different neural areas and cell types. Here, we place these consciousness states on a spectrum of approximated widespread membrane potential values with anxiety states being the most depolarized, followed by waking states, and rapid eye movement sleep. We propose that although these widespread membrane potential changes are minor, they may underlie transitions between and maintenance of varying levels of arousal. Further research on these mechanisms could provide insights into how the brain functions. This homeodynamic arousal mechanism involves the established feed-forward and feedback signaling between the ascending reticular activating system and the hypothalamus, as well as the modulation by cardiorespiratory oscillatory feedback from the body. Understanding the basic mechanisms responsible for the states of sleep, waking, and anxiety could lead to better treatment options in health and disease. (shrink)

After China, India has the most skewed sex ratio at birth. These two Asian countries account for about 90 to 95% of the estimated 1.2 to 1.5 million missing female births annually, worldwide, due to gender-biased sex selection. To understand this extreme discrimination against girls, this article examines the gendered biopolitics embedded in population policies, new sex selection technologies, and in the social reproduction of patriarchal society. The ethical consequences of advanced reproductive technologies, which remove the moral turpitude around gender-based (...) sex selection by reformulating it into a “modern”, “scientific” endeavour, facilitating the rise of “missing girls”, make this an issue of gender justice, as noted by the World Population Report 2020. This article argues that unpacking gendered biopolitics within the household is crucial to understanding the reproduction of son preference and daughter aversion since it is here that reproduction and parenthood are subjected to biopolitical governance. We discuss how “biosocial” strategies of the household aimed at producing the “desired” and “right” family of more sons at the cost of daughters are operationalized through women’s bodies with a view to family mobility. While women and girls continue to bear the burden and costs of social reproduction that lie at the heart of the patriarchal capitalist system of accumulation, a perusal of more recent studies suggests the beginning of an equalizing trend of parental investments, especially in the health and education of daughters who are “allowed” to be born. We suggest that familial enhancement of girls’ human capital can help as a means of developing girls’ capabilities and agency, enhancing their power in the biopolitics of the family and increasing their “bio-value” in parents’ eyes.

In this thesis I have retrieved the modern language of the law of nature between the period 1625--1672. I have reconstructed this language as a response to the seventeenth century breakdown of society in Europe. ;In Chapters 1, 2 and 3, I lay out Hugo Grotius' moral and political theory grounded in three irreducible principles of self-preservation, the primacy of society and consent. These principles lead Grotius to develop a rich and pluralistic theory. ;Thomas Hobbes's theory calls into question the (...) complex Grotian social and political arrangement and in its place provides an absolutist and homogeneous conception of the state. This is treated in Chapter 4. ;In Chapters 5 and 6, I lay out Samuel Pufendorf's moral and political theory. Pufendorf accepts Grotius's and Hobbes' initial premises but argues for a 'regular' or homogeneous state. ;The retrieval of the law of nature proposed in this thesis is important, for it radically calls into question the conventional manner in which we understand the seventeenth century. Among other things, this work illuminates the common foundation shared by contemporary liberals, communitarians and more radical theories. (shrink)

This article is a critical examination of practices and representations that constitute international education. While international education has provided substantial contributions and benefits for nation-states and international students, we question the discourses and practices which inform the international education export industry. The ‘brand identities’ of receiving or host countries imply that they are welcoming, respectful of multiculturalism and have a well established intellectual history, in contrast to international students' embodied experiences. There is also a tendency to represent and regard international (...) students as disembodied learners. We conclude that these disjunctures between disembodied representations and embodied experiences are undermining the kinds of cosmopolitan sensibilities that international education claims to provide.

_Universities and Globalization: To Market, To Market_ examines the operations of power and knowledge in international education under conditions of globalization, with a focus on the three biggest exporters of higher education--the United States, Australia, and the United Kingdom. An interdisciplinary approach based on the core social sciences is used to explore the power relations that shape global education networks. The role of nation-states in creating the conditions for education markets and the desire for a Westernized template of international education (...) in the postcolonial world is discussed. The volume offers a sophisticated attempt to recast international education as a series of geopolitical and geoeconomic engagements that transcend simple supply and demand dynamics. Engaging with the theoretical debates about education and globalization, this book examines global cultural "flows" and boundary crossings, the cultural economy of education networks, and the possibilities for supra-territorial subjectivities. International education markets are examined from the perspectives of both first world producers and postcolonial consumers. By investigating how first world universities imagine and enact the global in their marketing practices, the expressions of cultural diversity valued by education markets, and the types of individual and institutional subjectivities merging from markets, _Universities and Globalization: To Market, To Market_ offers students, faculty, administrators, marketing consultants, and others who work in the area a highly nuanced account of the global relations fostered by education markets. This original, critical examination of the forms and cultural politics of international education is a significant contribution to the field. (shrink)

This article uses Foucault’s concept of the care of the self to interrogate the accounts of ethical agency provided by professionals involved in the settlement of refugees, in a global and national context marked by fear of the stranger and the embrace of neoliberal political rationalities. An argument is made to ‘free the professional self’ by refusing an individualised, psychologised and dehistoricised approach in working with refugees and asylum seekers. In its place, a threefold ‘ethics of engagement’ for ‘international citizenship’ (...) is proposed as a way forward to further professionalism and civic action. By understanding the refugee problem as an ‘integral part of North-South relations’ rather than as a ‘Third World’ problem, new possibilities are opened for an ethics of civility and an ethics of care.

The main economic activity of the people of Eritrea is agriculture: crop production and livestock herding. Agriculture mainly comprises mixed farming and some commercial concessions. Most agriculture is rain-fed. The main rain-fed crops are sorghum, millet and sesame, and the main irrigated crops are all horticultural crops like bananas, onions and tomatoes and cotton. The major livestock production constraints are disease, water and feed shortages and agricultural expansion especially in the river frontages. The agricultural sector employs eighty percent of the (...) working population, but its production has not managed to cover internal food demand and is forced to cover nearly 50 per cent of its annual cereal requirements through imports-commercial and food assistance. Like most African countries, Eritrea is also a victim of the problem of food insecurity. In good years the country produces only about 60 per cent of its total food needs and in poor years, it produces no more than 25 per cent. On average, once in 10 years, the country is threatened with famines. Annual crop production depends on rainfall that is variable and unevenly distributed from year to year. Therefore, the primary goal of Eritrea is to guarantee food security by introducing modern technology, irrigation, terracing, soil and water conservation, with less dependence on rainwater. Thus the Government has articulated its food policy, which stresses national ownership of grant food assistance and to achieve food security in the coming five years. The policy indeed encompasses all sectoral policies and represents the Government's engagements with regard to food security. Despite the general trends of improvement in the economy of Eritrea, it has not yet fully recovered, and thus will still continue to require variable degrees of food assistance for the coming few more years. Based on this historical and recurrent food insecurity in Eritrea, an attempt is made in this paper to assess the agriculture development and food policy in the country. Furthermore, the paper captures the available food security policy proposals of Eritrea and eventually draws conclusions. (shrink)

Food security is about ensuring that all people at all times have both physical and economic access to the basic food they need.

Eritrean higher education faced numerous challenges over many years. It was particularly suffered during the colonial periods. Eritrea exerted its efforts to develop its dilapidated educational system with the advent of its independence. Eritrea celebrated its sixteenth birthday recently. However, the educational challenges in higher education still remain high. The government of Eritrea established different colleges in different administrative regions. The University of Asmara is the only university in the country that had to be revitalized after its devastation by the (...) 30-year war of independence. Since independence, the University has been able to contribute to the nation's skill manpower considerably. This paper examines higher education of Eritrea for about 60 years period.

All over the world, distance mode of education is gaining a momentum and becoming more popular than conventional education. It is a system in which schools, universities and other educational agencies offer instruction wholly or partly by mail. Eritrea, a newly independent country in Africa has been facing many challenges particularly in its education sector. It does not have sufficient educational institutions at tertiary level, thus, distance learning which is more cost effective, could be an alternative method of higher education (...) for this country. The distance education programme could promote higher education by providing access to large number of urban people and disadvantaged groups in rural and remote areas including working people, fighters, women and other adults. An attempt has been made in this paper to discuss various issues related to the establishment and development of distance education. It also provides the distance education programmes that so far undertaken in Eritrea and highlights the potential for the distance education in the country. (shrink)

The ongoing national reconstruction process of Eritrea is centered on the educational reformation. The Government of Eritrea has developed educational policy on top priority of national development which demands the emergence of new class of trained youth blended with disciplined mind with skill instead of raw graduation.

It had installed about eight colleges at tertiary level within a short span of time to build manpower (...) resource required for present and future. This article analyses the strengths and weakness of the policies, planning and the infrastructure requirements to meet the intended goal. The outcome of the educational reformation is expected to have a profound effect on the development of the Nation. Hence, it becomes curious watch for the educational reformists around the globe.

Poverty is one of the serious problems of the world. The problem is more severe in Africa. Eritrea is 16 years old young nation got independence from Ethiopia. The economy of the country was quite good during 1993-97. Later, however, Eritrea has been exposed numerous challenges such as drought, famines, war. As a result, the poverty has become more rampant in the country where more than 66 percent people live below poverty line. Some families live on remittances. The government has (...) taken some poverty alleviation measures, the poverty did not come down due to lack of resources and the poor implementation of the program.

The role of Eritrean women in thirty years war of independence brought major changes and reflects in the present demography and economy of Eritrea in the development arena. Their participation in the economy contributes to local production and income by filling the gaps left by men who died in the war or who have left the country and settled in different parts of the world. Despite the growing importance of women for the formal economy, jobs and self-employment opportunities available to (...) women are still clustered in low-productivity and/or low-status industries. To cope with the growing number of female-headed households, Eritrea needs to increase the earning potential of women. This paper indicates that providing women with education at secondary or tertiary level is one way to go. This paper deals with, why Eritrean women are entering into the labour markets: one, family ties and control of women is weakened due to absent men and increasing divorce rates. The second, there is a shortage of male breadwinners. The third, growing education levels increase their earning potential. (shrink)

Women play a key role in economic growth and development, yet they are still discriminated against in economic life. Eritrea has extreme poverty and more than 66 percent of people live below poverty line. Eventually, the number of poor households in the country is high. Many are women-headed households, whose husbands died during the conflicts or who are now serving in the National Service. Women-headed households are particularly vulnerable. The Savings and Micro Credit Program (SMCP) provides major microfinance to women (...) entrepreneurs. A small group of women and men were interviewed to ascertain their successes and problems with micro credit and enterprise development. This paper delves how the women benefited from the microfinance program and got rid of their poverty.

Transformed RAVAL NOTATION solves Syllogism problems very quickly and accurately. This method solves any categorical syllogism problem with same ease and is as simple as ABC… In Transformed RAVAL NOTATION, each premise and conclusion is written in abbreviated form, and then conclusion is reached simply by connecting abbreviated premises.NOTATION: Statements (both premises and conclusions) are represented as follows: Statement Notation a) All S are P, SS-P b) Some S are P, S-P c) Some S are not P, S / PP (...) d) No S is P, SS / PP (- implies are and / implies are not) All is represented by double letters; Some is represented by single letter. No S is P implies No P is S so its notation contains double letters on both sides. -/- RULES: (1) Conclusions are reached by connecting Notations. Two notations can be linked only through common linking terms. When the common linking term multiplies (becomes double from single), divides (becomes single from double) or remains double then conclusion is arrived between terminal terms. (Aristotle’s rule: the middle term must be distributed at least once) -/- (2)If both statements linked are having – signs, resulting conclusion carries – sign (Aristotle’s rule: two affirmatives imply an affirmative) -/- (3) Whenever statements having – and / signs are linked, resulting conclusion carries / sign. (Aristotle’s rule: if one premise is negative, then the conclusion must be negative) -/- (4)Statement having / sign cannot be linked with another statement having / sign to derive any conclusion. (Aristotle’s rule: Two negative premises imply no valid conclusion) Syllogism conclusion by Tranformed Raval’s Notation is in accordance with Aristotle’s rules for the same. It is visually very transparent and conclusions can be deduced at a glance, moreover it solves syllogism problems with any number of statements and it is quickest of all available methods. By new Raval method for solving categorical syllogism, solving categorical syllogism is as simple as pronouncing ABC and it is just continuance of Aristotle work on categorical syllogism. It’s believed that Boole's system could handle multi-term propositions and arguments, whereas Aristotle could handle only two-termed subject-predicate propositions and arguments. For example, it’s claimed that Aristotle's system could not deduce: "No quadrangle that is a square is a rectangle that is a rhombus" from "No square that is a quadrangle is a rhombus that is a rectangle" or from "No rhombus that is a rectangle is a square that is a quadrangle". Above conclusion is reached at a glance with Raval's Notations (Symbolic Aristotle’s syllogism rules). Premise: "No (square that is a quadrangle) is a (rhombus that is a rectangle)" Raval's Representations: S – Q, S – Q / Rh – Re, Rh – Re Premise: "No (rhombus that is a rectangle) is a (square that is a quadrangle)". Raval's Representations: Rh – Re, Rh – Re / S – Q, S - Q Conclusion: "No (quadrangle that is a square) is a (rectangle that is a rhombus)" Raval’s Representations: Q – S, Q – S / Re – Rh, Re – Rh As “ Q – S” follows from “S – Q” and “Re – Rh” from “Rh – Re”. Given conclusion follows from the given premises. Author disregards existential fallacy, as subset of a null set has to be a null set. -/- . (shrink)

Basic Argument forms Modus Ponens , Modus Tollens , Hypothetical Syllogism and Dilemma contains ‘If –then’ conditions. Conclusions from the Arguments containing ‘If –then’ conditions can be deduced very easily without any significant memorization by applying Raval’s method. Method: In Raval’s method If P then Q is written as P (2$) – Q (1$) and viewed numerically, in currency form i.e. P is viewed as 2$ and Q is viewed as 1$ and implications from this notations are valid conclusions. If (...) one has 2$ then he definitely have 1$. If one do not have 2$, he may not have 1$. If one is having 1$, he may not have 2$. If one do not have 1$, he definitely doesn’t have 2$. (shrink)

Here Author proves that universal affirmative (UA) and universal negative (UN) do have existential import i.e. definitely have at least one element and existential import theory in syllogism is an illusion. This illusion is due to the fact that Universal set contains infinite number of null sets (void points) identical in all respects but none have individual address. While existential theory wrongly assumes existence of only one possible null set (void point) for a given set.

Effective and personalized treatment relies heavily on skin disease categorization. In the stratification of skin disorders, it is crucial to identify the subtypes of illnesses to provide an efficient therapy. To attain this aim, researchers have focused their attention on cluster algorithms for the stratification of skin disorders in recent decades. But, cluster algorithms have real-world drawbacks, including experimental noises, a large number of dimensions, and a poor ability to comprehend. Cluster algorithms, in particular, determine the quality of clusters using (...) a single internal evaluation operation in the majority of cases. A single internal assessment procedure is difficult to design and robust for all datasets, which is a problem. The multi-objective particle swarm obtained high sensitivity in the existing work, but it is not able to anticipate all kinds of classes. An optimized cluster distance parameter for K-means clustering is determined using a hybrid particle swarm and moth flame optimization. Multi-objective is guided by two cluster value indices, including the K-means clustering misclassification rate and neural network classification rate. Hybrid PSO will solve the multi-objective problem to identify the optimal cluster for clustering. On the dermatological dataset from the UCI repository, MATLAB R2020a will be used to evaluate the proposed method. This will be followed by an evaluation of the proposed method’s performance using the cluster evaluation indices. (shrink)

Background: Educated women tend to have a greater awareness of the existence of ANC services, more aware of health problems, know more about the availability of health care services, and utilize the information more effectively than non-educated women. Moreover, higher levels of education tend to positively affect healthseeking behaviors, and education may increase a woman’s control over her pregnancy and expose women to more health education messages and campaigns, enabling them to recognize danger signs and complications and take appropriate action. (...) In this study, we tried to analyze to what level the maternal education can influence the antenatal care services and childcare. Methods: A community-based cross-sectional study was conducted on 93 randomly selected mothers who have children less than 7 years by using a pre-tested structured questionnaire for data collection at various tribal villages, at an average 25 kms away from Adilabad town from April-October 2019. Analysis was done using SPSS for windows version 16, Microsoft excel and Open epi website. Results: Out of 93 study subjects, 19.3% (18) of the study subjects were not registered for the antenatal services. Higher the maternal education higher the age at pregnancy (p<0.05), was associated with more preference for deliveries by doctors (p<0.05). More the frequency of exclusive breast feeding, long lasting breast feeding was associated more than a year (p<0.05), a smaller number of children with wasting (p<0.05). Conclusion: This study revealed that utilization of ANC services was relatively better for the mother’s educated higher than secondary school, but they are still low. Educational status is important in having more health seeking behavior. In this study, it proves that health education is more important than the mere school education which can help to improve knowledge on ANC. (shrink)
