  • Polyploidy
    Genomic analysis also has shown that one of the important mechanisms of evolution is multiplication of chromosome sets, resulting in polyploidy (“many genomes”). In plants and animals, spontaneous doubling of chromosomes can occur. In some plants, the chromosomes of two related species unite via cross-pollination to form a fusion product. This product is sterile because each chromosome needs a pairing partner in order for the plant to be fertile. However, the chromosomes of the fusion product can accidentally double, resulting in a new, fertile species. Wheat is an example of a plant that evolved by this means through a union between wild grasses, but a large proportion of plants went through similar ancestral polyploidization.

  • The diagnostic term attention deficit/hyperactivity disorder (ADHD) refers to individuals who display patterns of inattention, impulsivity, and overactive behavior that interfere with daily functioning (American Psychiatric Association [APA], 2013). The Diagnostic and Statistical Manual (DSM) V (APA, 2013) criteria for diagnosing ADHD list three types of ADHD and the accompanying characteristics. Predominantly inattentive type. The student may: o submit inaccurate or incomplete work, o have difficulty attending to conversations, activities, or tasks, o be easily distracted, o have difficulty following directions, o frequently lose materials, and/or o have difficulty organizing tasks and materials.

  • ADHD Students and Classroom Considerations
    https://education.wm.edu/centers/ttac/documents/packets/adhd.pdf The culture of the classroom can either support or create barriers to student success (Piffner,2011).    Factors that foster attention, positive behavior, and academic and social success includeestablishing positive relationships with students, adopting classroom management techniques,and creating a physical arrangement that facilitates learning. It is often a positive relationship with one teacher that facilitates school success for a studentwith ADHD (Piffner, 2011).    When teachers connect with students and appreciate their unique skills and interests, students are more likely to strive for achievement and positively respond to classroom rules and procedures. When using a proactive approach to classroom management, teachers support all students andcreate conditions that prepare them for learning (Piffner, 2011).    Some strategies for positive management include clear directions, meaningful feedback, and opportunities for collaboration with peers. Here are some others.   Opportunities to RespondStudents with ADHD often have the most trouble attending during drill-and-practice assignments because of the repetitive nature of the tasks. Peer-mediated approaches such as those enumerated in the next screens are particularly effective for students with ADHD in such cases, because they increase students’ opportunities for engagement and active learning (Piffner, 2011).    In creating peer-mediated activities, the teacher may need to choose students whoseskill levels complement each other. Students with and without attention difficulties andimpulsivity should be considered for peer partnerships.   Peer TutoringPeer tutoring is one of the more effective strategies for students with ADHD, because it provides many of the same supports as one-to-one instruction. It facilitates the acquisition of both academic and social skills.    Peer tutoring is most effective when training is provided to participating students (Piffner, 2011). Tutors need to be taught how to be prepared with materials needed for the session and howto give positive and corrective feedback to their partner (Greenwood & Delquadri,1995).   Cooperative LearningCarefully structured cooperative learning groups in which each student is assigned a role and has clear expectations for desired outcomes are very helpful for students with ADHD. The more structured the cooperative activity, the more likely it is that these students will succeed.Sharing Strategies Think, Pair, Share/Square Share/Group Share: Using thisapproach, students work with peer partners to discuss the lesson, check each other’swork, and share strategies.

  • The following organizational supports are particularly useful. Students should be taught to use these tools through teacher modeling and guided practice with feedback before being expected to use them more independently.

  • They are more likely to respond positively when teachers establish class routines and set procedures and maintain a well-organized learning environment. Clear rules and advanced planning are keys to success for teachers of students with ADHD.

  • Culture encompasses religion, food, what we wear, how we wear it, our language, marriage, music, what we believe is right or wrong, how we sit at the table, how we greet visitors, how we behave with loved ones, and a million other things," Cristina De Rossi, an anthropologist at Barnet and Southgate College in London, told Live Science.

  • Environmental resource management is the management of the interaction and impact of human societies on the environment. It is not, as the phrase might suggest, the management of the environment itself. Environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering ethical, economic, and scientific (ecological) variables

  • individual scholars
    While individual scholars naturally have different research emphases or application contexts, common to all systemic linguists is an interest in language as social semiotic (Halliday 1978)--how people use language with each other in accomplishing everyday social life. This interest leads systemic linguists to advance four main theoretical claims about language:These four points, that language use is functional, semantic, contextual and semiotic, can be summarized by describing the systemic approach as a functional-semantic approach to language."

  • Role-and-Reference Grammar (RRG) and Systemic Linguistics (SL)
    "There are very many functionalist approaches which have been put forward, and they are often very different from one another. Two prominent ones are Role-and-Reference Grammar (RRG), developed by William Foley and Robert Van Valin, and Systemic Linguistics (SL), developed by Michael Halliday. RRG approaches linguistic description by asking what communicative purposes need to be served and what grammatical devices are available to serve them. SL is chiefly interested in examining the structure of a large linguistic unit--a text or a discourse--and it attempts to integrate a great deal of structural information with other information (social information, for example) in the hope of constructing a coherent account of what speakers are doing. "Functionalist approaches have proved fruitful, but they are usually hard to formalize, and they often work with 'patterns,' 'preferences,' 'tendencies,' and 'choices,' in place of the explicit rules preferred by non-functional linguists."

  • healthcare
    healthcare is the maintenance or improvement of health via the prevention, diagnosis, treatment, recovery, or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training and other health professions are all part of health care. It includes work done in providing primary care, secondary care, and tertiary care, as well as in public health.
