The support includes coordination blood pressure chart cheap vasotec 5mg, political representation and defense of interests pulse pressure of 80 generic vasotec 10 mg on line, literacy and other training arteria pudenda externa order vasotec 10mg amex, and cultivation methods for sustainability of production systems and social services blood pressure and pulse rates discount vasotec 5mg otc. In some cases, these farmer organizations have taken direct responsibility for research and dissemination (as in the Coffee Producer Federation of Colombia). Access to water resources has been improved by water user associations and organizations ensuring access to water rights through user-based, agency and market allocations. Goals E, S Certainty B Range of Impacts Scale 0 to +3 G Specificity Mainly in tropical countries Many different products can be processed from a single crop. The branding of products by area of origin is becoming an important marketing tool affecting the competitiveness of local products in the tropical food sector (Daviron and Ponte, 2005; van de Kop et al. Competitiveness in the international market involves the promotion of distinctive properties of tropical foodstuffs. In aquaculture, there is increased coordination of private sector-led production and processing chains. Goals E, S Certainty B Range of Impacts 0 to +2 Scale G Specificity Wide applicability Dissatisfaction with performance of government managed irrigation has led to the promotion of participatory irrigation management over the past twenty years. However, problems remain with efficiency of operations, maintenance, sustainability and financial capacity. The involvement of private sector investors and managers is gaining credibility as a way to enhance management skills, and relieve the government of fiscal and administrative burdens (World Bank, 2007a). Likewise, in Mexico, Turkey and Nepal, transferring irrigation management to farmers has resulted in improved operation, better maintenance of infrastructure, reduced government expenditure, and increased production (World Bank, 1999). In many countries, this evolution has also raised new ques- Formal and informal links between small-scale producers and large processing companies are contributing to more efficient and competitive aquaculture (shrimp, Vietnamese catfish, African catfish and tilapia), resulting in better quality for consumers, and secured margins for producers (Kumaran et al. Export certification schemes are further streamlining production, processing, distribution and retail chains (Ponte, 2006). Seasonal fluctuation in fruit and vegetable supplies is a major problem in the marketing of perishable products. Goals N Certainty B Range of Impacts -3 to +1 Scale G Specificity Wide applicability Various approaches have been developed to reduce the impacts of seasonality. Initiatives like these are enhanced by the development of varieties and production technologies that expand the productive season and overcome the biotic and abiotic stresses, which occur during the off-season (Tchoundjeu et al. Goals N, D Certainty C Range of Impacts 0 to +3 Scale R Specificity Wide applicability "participatory" models. However, the regulatory environment for food safety can be seen as an opportunity to gain secure and stable access to affluent and remunerative new markets, and generate large value addition activities in developing countries (World Bank, 2005b). Food standards are increasingly important and have implications for consumer organizations and private firms. Goals N Certainty B Range of Impacts 0 to +3 Scale G Specificity Wide applicability New instruments of protection and competitiveness have emerged as "standards" and new forms of coordination between actors in the food chain have been developed in response to consumer and citizen concerns. Actors in the food chain work together to specify acceptable production conditions and impose them on suppliers (Gereffi and Kaplinsky, 2001; Daviron and Gibbon, 2002). The multiplication of these standards, which are supposed to improve food safety, preserve the environment, and reduce social disparities, etc. Food labeled as "organic" or "certified organic" is governed by a set of rules and limits, usually enforced by inspection and certification mechanisms known as "guarantee systems". Goals H, E, S, D Certainty A Range of Impacts Scale +1 to +3 G Specificity Wide applicability To face the inequalities that accrue from benefits to largescale producers, standards have been developed to encourage small-scale producers. This support has helped small organizations to market their produce directly by working similarly to that of forest certification. Where foreign buyers impose labor standards, the terms and conditions of employment in the formal supply chains are better than in the informal sector. Enforcement of food standards furthermore improve the working environment and ensure that agricultural workers are not exposed to unhealthy production practices. The globalization of trade in agricultural products is not an import-export food model that addresses poverty and hunger in developing countries. Goals N, D Certainty C Range of Impacts -4 to 0 Scale G Specificity Wide applicability With very few exceptions, synthetic pesticides, mineral fertilizers, synthetic preservatives, pharmaceuticals, sewage sludge, genetically modified organisms and irradiation are prohibited in all organic standards. There are numerous informal organic regulation systems outside of the formal organic certification and marketing systems. These are often called "peer" or Many complex factors affect the economy of a country.
In the 1960s prehypertension how to treat buy generic vasotec 5 mg on-line, a number of reports associated waterborne Giardia infections with outbreaks of diarrheal illness hypertension 30s generic vasotec 10mg on line. In a large outbreak among skiers at a single ski resort blood pressure medication that doesn't cause cough vasotec 5mg with mastercard, 59 persons were found to be excreting Giardia cysts (10) blood pressure ranges nhs purchase vasotec 10mg amex. The mean duration of illness was 44 days (median 38 days), and only two had fewer than 10 days of illness. Studies of American and Finnish travelers to the Soviet Union, especially Leningrad (St. Petersburg), have also given valuable information regarding the spectrum of illness associated with Giardia infection. Diarrhea is present in most patients and is frequently accompanied by nausea or vomiting, abdominal bloating, and flatulence, although uncommonly patients may present with constipation. Bloody stools are rare and should suggest an alternative diagnosis or dual infection. The mean duration of symptoms in the various studies has been as low as 11 days (28), but an average duration of 6 weeks (10,26) to 10 weeks (27) in the absence of treatment has been documented in other studies. A waxing and waning course of illness is not uncommon, and patients with illness lasting from months to years have been reported (31). In the United States the incidence rate is estimated to be between 50 and 1000 cases per 100,000 population annually (32). The rate of hospitalization for severe giardiasis is 2 per 100,000 population annually, a rate that is comparable to that of hospitalization for shigellosis (33). For example, the infection rate in Peruvian children living in a shantytown near Lima was 95% by age 2, and 98% became reinfected within 6 months after treatment (34). From the tropics to northern Russia or Alaska, infection rates with Giardia are extremely high when inadequately purified drinking water is used. There is a marked seasonality for infections acquired in the United States, with a peak in the late summer (35). Cases have also been associated with homosexual activity (38,39), camping (40), or foodborne acquisition. Acquisition of giardiasis has been associated with shallow well water (42), untreated surface water, surface water that is chlorinated only, and filtered water that is contaminated after filtration (43,44). Giardiasis has also been reported after recreational water exposure (45), but this is less common (44). Although foodborne transmission is less commonly documented than waterborne transmission, there have been a number of well-documented reports of foodborne transmission. Many cases of foodborne transmission of pathogens are sporadic rather than epidemic and are even less adequately recognized than those occurring as parts of epidemics. Since the cyst is infectious immediately after being passed, foodborne transmission is a risk whenever contaminated water is used to wash fruits or vegetables that are subsequently consumed without cooking and is likely to be a common source of infection in areas with contaminated water supplies, as is found in many of the developing countries. In one outbreak, half of 60 employees of a school in rural Minnesota developed giardiasis, but none of the students were infected (30). The salmon had been opened by a woman caring for a grandson subsequently found to have asymptom- Copyright 2003 by Marcel Dekker, Inc.
Students have to silently categorize themselves with others who have similar cards (types of health and exercises blood pressure top number high buy vasotec 10mg line, states of matter pulse pressure graph discount vasotec 5mg, parts of speech) arrhythmia signs and symptoms cheap 5mg vasotec free shipping. The teacher or the students create movements to help them remember important ideas about the learning heart attack vol 1 pt 3 buy vasotec 5 mg without a prescription. For example, math students could make up movements to recall that the formula for slope is "rise over run," or students could make up movements to help recall the difference between longitude and latitude. Students act out what they have learned and other students have to guess what they are acting out about the learning. Kryza (b) Line students up with a partner around the clock so they can see the clock. Students become the person, place, or thing and act out who, what, or where they are. Think/Pair/Share Students are given a question or prompt to think about in their heads for 1 min. Then the teacher leads a whole class share by drawing names randomly and asking those students to share. Ways to Write to Chew Learning Logs/Journals Students use writing logs to process learning in their own words. Note-taking Strategies Students create 1/3, 2/3 notes, for gathering facts and summarizing information; Double-Entry Journals for gathering facts and processing with a guiding question or perspective from the teacher. Blogs Students keep a blog of their thoughts, like a journal only using technology. Ways to Draw/Design to Chew Comic Strips Students create comic strips that summarize new learning. Doodle Notes As students are reading or listening to you, allow them to doodle, sketch, ideas, thoughts, etc. Check: Student Self-Assessment on Mindsets and Skills Sets For the purpose of this chapter, the check focus will be on student self-assessment. If students are going to take charge of their own learning and control of their executive functioning mindsets and skill sets, they need frequent practice at self-assessing. Marzano, Pickering, and Pollock note, "Teaching about effort, as suggested previously, might work for some students, but others will need to see the connection between effort and achievement for themselves. A powerful way to help them make this connection is to ask students to periodically keep track of their effort and its relationship to achievement" (Marzano et al. Know Your Target: Executive Functioning Skill Sets Grow When We Teach for Meaning How do we invite students who are reluctant because they are bored or apathetic and who feel no connection with what is being taught to engage with us in the learning journey? We engage them by focusing on the richness of learning and making connections to real life instead of focusing on outcomes (test scores and grades) that hold little meaning to them. To invite reluctant learners to come along on our journey and to build their behavioral and metacognitive executive functioning skills, we must create an environment in our classroom that embraces their individuality, includes them in community, and nurtures their curiosity and desire to see the relevance in what we are teaching. Clear Learning Targets Keep Students on Course A skilled sailor always plots his course before heading out into open water. He determines his coordinates, checks out the weather conditions, and makes sure his equipment is working. Leaving the shore prepared is essential for a successful journey, but once he leaves shore, there is still work to be done. Winds, a tangled sail, shifting currents, and the occasional squall can veer the ship off course. But the sailor continually monitors his progress, assesses his place on the journey, and uses the information to make quick decisions to get him back on course toward his destination. If students are to develop and monitor their executive functioning skills, they need to know where they are going and how to get there.

The Assessment of Executive Function Using the Cognitive Assessment System: Second Edition Jack A. We will begin with a brief discussion of the relevant history of the concept of executive function, the ways it has been conceptualized, and how it has been measured. Finally, we will provide a discussion of an executive function intervention method that has been used for improving math and reading comprehension. The Concept of Executive Function One of the most remarkable capacities in the human brain is its ability to reflect and direct itself. The concept of executive function is inextricably linked to the functions of our frontal lobes. Early groundwork for defining the executive function system was put forth by Luria (1966). Luria proposed the existence of a system in charge of intentionality, goal formulation, the action plans leading to these goals, the identification of goal-appropriate cognitive routines, the sequential access to the routines, the temporal ordered transition from one routine to the other, and the evaluation of our actions or the outcome. In order to effectively cope with such transitions, mental flexibility is required. Mental flexibility can be conceptualized as the ability to respond efficiently to unanticipated contingencies within our environment.
