Media And Technology

Media and technology are ubiquitous elements of our daily lives, and their use can offer many benefits and rewards. At the same time, decisions about how individuals structure their use of media can be informed by consideration of whether, and if so how, the mind and brain are shaped by different use patterns. Here we review the growing body of research that investigates the cognitive and neural profiles of individuals who differ in the extent to which they simultaneously engage with multiple media streams, or ‟media multitasking.” While the literature is still sparse, and is marked by both convergent and divergent findings, the balance of evidence suggests that heavier media multitaskers exhibit poorer performance in a number of cognitive domains, relative to lighter media multitaskers (although many studies find no performance differences between groups). When evidence points to a relationship between media multitasking level and cognition, it is often on tasks that require or are influenced by fluctuations in sustained goal-directed attention. Given the real-world significance of such findings, further research is needed to uncover the mechanistic underpinnings of observed differences, to determine the direction of causality, to understand whether remediation efforts are needed and effective, and to determine how measurement heterogeneity relates to variable outcomes. Such efforts will ultimately inform decisions about how to minimize the potential costs and maximize the many benefits of our ever-evolving media landscape.

Human memory, as a product of the mind and brain, is inherently private and personal. Yet, arising from the interaction between the organism and its ecology in the course of phylogeny and ontogeny, human memory is also profoundly collective and cultural. In this review, I discuss the cultural foundation of human memory. I start by briefly reflecting on the conception of memory against a historical and cultural background. I then detail a model of a culturally saturated mnemonic system in which cultural elements constitute and condition various processes of remembering, focusing on memory representation, perceptual encoding, memory function, memory reconstruction, memory expression, and memory socialization. Then I discuss research on working memory, episodic memory, and autobiographical memory as examples that further demonstrate how cultural elements shape the processes and consequences of remembering and lay the foundation for human memory. I conclude by outlining some important future directions in memory research.

The role of electron microscopy and associated techniques is assured in diagnostic pathology. At the present time, most of the progress has been made on tissues examined by transmission electron microscopy (TEM) and correlated with light microscopy (LM) and by cytochemistry using both plastic and paraffin-embedded materials. As mentioned elsewhere in this symposium, this has revolutionized many fields of pathology including diagnostic, anatomic and clinical pathology. It began with the kidney; however, it has now been extended to most other organ systems and to tumor diagnosis in general. The results of the past few years tend to indicate the future directions and needs of this expanding field. Now, in addition to routine EM, pathologists have access to the many newly developed methods and instruments mentioned below which should aid considerably not only in diagnostic pathology but in investigative pathology as well.

Lecturer plays an important role in teaching Englishas a foreign language, in spite of the success of teaching English itself depends on the many factors, one of them is students’ participation in the English class. In the other words, the teaching of English becomes useful and more systematically when the lecturer is fully aware of the aims and values of teaching of English subject since the core principle of any teaching  is “know what you do and only do what you know”. Hence it is essential to understand the aims and values of teaching English. In linguistics study,performance and competence are different, competence is study about language rules in the abstract form or one’s capacity to use a language, while performance is the application of one’s ability in the concrete form, or the actual application of this competence in speaking or listening. Chomsky (1965:18) said that  performance is the effect or the application of competence. Further he said that clearly, the actual data of linguistic performance will provide much evidence for determining the correctness of hypotheses about underlining linguistic structure. Notice the following figure. The data collection procedures in the present study are based on classroom participant observation, student interviews, and questionnaire  are the primary sources of data collection. As a point of departure, unstructured interviews conducted with English and students to gain initial understanding of the learning English as a foreign language. This also serves as a pilot study, paving the way for designing the guidelines for the semi structured individual interviews. Notes taken in these unstructured interviews were included in the data analysis. Taking lecture involves the lecturer and the students in formal setting. Lecturer is one who transfers special knowledge (English teaching materials) to his students in form of academic setting. They are engaged in academic norms, for example lecturer has qualified education (magister or doctorate degree) and the students  have already registered their status as a university student. The lecturer’s function is threefold. In the presentation stage of the material, the lecturer serves as a model, setting up situations in which the need for the target structure is created and modeling the new structure for students to repeat. The lecturer was required to be skillful manipulator, using questions, commands, and other cues to elicit correct sentences from the students. The students wanted the lecturer to give more opportunities for English practice. They can learn from mistakes and develop in real situation. Role play is one of methods can be applied in teaching English. The students like this methods (96%) because they can imitate and practice their English pronunciation.

This chapter presents the Distributed Adaptive Control (DAC) theory of the mind and brain of living machines. DAC provides an explanatory framework for biological brains and an integration framework for synthetic ones. DAC builds on several themes presented in the handbook: it integrates different perspectives on mind and brain, exemplifies the synthetic method in understanding living machines, answers well-defined constraints faced by living machines, and provides a route for the convergent validation of anatomy, physiology, and behavior in our explanation of biological living machines. DAC addresses the fundamental question of how a living machine can obtain, retain, and express valid knowledge of its world. We look at the core components of DAC, specific benchmarks derived from the engagement with the physical and the social world (the H4W and the H5W problems) in foraging and human–robot interaction tasks. Lastly we address how DAC targets the UTEM benchmark and the relation with contemporary developments in AI.

The cannabis plant (Cannabis sativa L.) produces an estimated 545 chemical compounds of different biogenetic classes. In addition to economic value, many of these phytochemicals have medicinal and physiological activity. The plant is most popularly known for its two most-prominent and most-studied secondary metabolites—Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD). Both Δ9-THC and CBD have a wide therapeutic window across many ailments and form part of a class of secondary metabolites called cannabinoids—of which approximately over 104 exist. This review will focus on non-cannabinoid metabolites of Cannabis sativa that also have therapeutic potential, some of which share medicinal properties similar to those of cannabinoids. The most notable of these non-cannabinoid phytochemicals are flavonoids and terpenes. We will also discuss future directions in cannabis research and development of cannabis-based pharmaceuticals. Caflanone, a flavonoid molecule with selective activity against the human viruses including the coronavirus OC43 (HCov-OC43) that is responsible for COVID-19, and certain cancers, is one of the most promising non-cannabinoid molecules that is being advanced into clinical trials. As validated by thousands of years of the use of cannabis for medicinal purposes, vast anecdotal evidence abounds on the medicinal benefits of the plant. These benefits are attributed to the many phytochemicals in this plant, including non-cannabinoids. The most promising non-cannabinoids with potential to alleviate global disease burdens are discussed.

Object. Despite a long and controversial history, psychosurgery has persisted as a modern treatment option for some severe, medically intractable psychiatric disorders. The goal of this study was to review the current state of psychosurgery. Methods. In this review, the definition of psychosurgery, patient selection criteria, and anatomical and physiological rationales for cingulotomy, subcaudate tractotomy, anterior capsulotomy, and limbic leukotomy are discussed. The historical developments, modern procedures, and results of these four contemporary psychosurgical procedures are also reviewed. Examples of recent advances in neuroscience indicating a future role for neurosurgical intervention for psychiatric disease are also mentioned. Conclusions. A thorough understanding of contemporary psychosurgery will help neurosurgeons and other physicians face the ethical, social, and technical challenges that are sure to lie ahead as modern science continues to unlock the secrets of the mind and brain.

The Relationship

We suggest a reconsideration of the role of ‘attachment orientation’ in the context of eating disorders and paediatric diabetes. Attachment orientation is a psychological construct that describes a relatively stable set of expectations and behaviours an individual relies upon in managing relationships. There is considerable evidence of an association between attachment orientation and the development and maintenance of disordered eating in individuals without diabetes, though evidence is more scant in populations with diabetes. We discuss the underpinning theory and critically examine the existing literature for the relationship between attachment orientation and disordered eating in paediatric diabetes. Finally, we draw on adjacent literatures to highlight potential future directions for research should this area be revisited. Overall, we contextualise our discussion in terms of patient-centred, holistic care that addresses the mind and body (i.e., our discussion of attachment orientation assumes a psycho-biological approach).

To Receive

In the Arabic language، the question is a method intended to seek knowledge of a specific thing. The most important thing that distinguishes the Arabic language from other languages is the diversity of its methods and its validity for various sciences and arts. God Almighty has honored it by making it the language of the Noble Qur’an، which He revealed to all people، and the many methods and diversity in the language make speech more accurate in approach، fuller in phrase، and systematized path and most sincere outlet. Therefore، the question is one of the pillars of the methods of the construction language، as it is not based on the building only، but the meaning is based on it as well. The most important characteristic that distinguishes the interrogative method from other methods; The high and influential ability in the mind and the soul of the addressee and its appeal to consideration، meditation and contemplation، and the reason for this is that the question is originally issued by a soul wishing to obtain a request for understanding and knowledge; The question arises to alert the mind and provoke feelings، and makes the soul ready to receive the thoughts and images that come out of the person who is casting.

An account of Edmund Burke’s central ideas about the Sublime and the Beautiful shows how the emphasis Burke gave to terror helped to shape the Gothic fiction of Ann Radcliffe and Mary Shelley. Focusing on examples from the poetry of William Wordsworth, Lord Byron, Charlotte Smith, Percy Bysshe Shelley, John Keats, and John Clare, the remainder of this essay explores the ways in which Romantic poets both thought about and attempted to represent those elements of the sublime that were instigated by their encounters with the natural world. What emerges as defining about these interactions between the mind and world is how imaginative impulses towards a sense of the sublime often led to a renewed sense of the material world and the very contingencies of existence they sought to transcend. Even Wordsworth’s more reverential response to the natural world as sacrosanct recognises the ‘awe’ of the sublime can be as much consoling as it is disturbing. These disturbing aspects of natural process and the sublime are self-consciously explored in the poetry of Shelley, who subjects notions of transcendence and idealism to sceptical scrutiny. With varying degrees of emphases, the poetry of Byron, Smith, and Clare elide distinctions between nature and culture to acknowledge a sublime more explicitly shaped by temporal and material processes. Finally, a key episode in Keats’s Ode to a Nightingale is read as exemplifying the many difficulties and complexities of the Romantic imagination’s encounter with, and its attempts, to represent transcendence and the sublime.

AbstractThere is strong contemporary interest in the application of traditional environmental knowledge (TEK) of physical environments and land-use patterns in northern Canada. This interest relates to land claims, land-use planning, cultural preservation, resource management, and environmental monitoring. The application of TEK to land and resource management is critically examined and a typology relating scale, user group, and the transformation of knowledge is developed. Of the many challenges facing the incorporation of TEK in resource-management initiatives, perhaps the greatest is the recognition of the appropriateness of scale. The conclusions reached in this paper reaffirm the notion that scale and context are key components in maintaining the validity and integrity of TEK. The primary role of TEK appears to be with providing the most valid and intelligible interpretations of local geographies and prescribing locally appropriate resource-management strategies.
