...Solutions to Grooming Teens for Adulthood Reasoning and Problem Solving CST 1 November 30, 2009 To solve a problem one must often dive beneath the surface of the reflected obvious to reveal the rest of the issue hidden in the depths below. In Task one for this course the question of what is the best way to prepare teen’s for a successful adulthood has been addressed through several viewpoints and approaches. Just as there are multiple approaches in rearing children, there does not appear to be a single solution to the problem. Upon investigation it quickly becomes apparent that various groups can look at the same issue and will ultimately form different solutions that reflect their own skew on the problem. A closer look at example solution’s utilizing life skills through school settings, community resources, and Socratic home environments will demonstrate this concept. As an educator I believe that preparation is gleaned through understanding and understanding is gleaned from education. My solution would involve taking an active approach in educating the future educator by preparing the young to facilitate life skills for themselves and their own children one day. Equipping children with life applications of what they potentially will face as an adult is much like training a soldier for battle. Our county does not expect our military personnel to enlist and not receive training for what they will expect to encounter. Our children should not...

...Cell membranes are a selectively permeable phospholipid layer that act as a barrier between the internal and external environments of the cell (Singer and Nicolson 1972). Osmosis is the movement of solvent across a semipermeable membrane from low solute to high solute concentration; osmolarity is the concentration of an osmotic solution. Tonicity describes the relative concentrations of two solutions to determine movement of diffusion of solute across the membrane separating the solutions. The permeability of the rabbit red blood cell membrane is explored, factors varying the degrees of permeability to different solutes, and the effects on the cell from this movement of solutes and water across the membrane. The resultant effects when rabbit red blood cells are introduced to solutions of varying tonicity – isotonic, hypotonic, and hypertonic – are also observed. The permeability of the cell membrane to various organic solutes based on factors like molecular weights and lipid-water partition coefficients is also studied. The permeability of a cell membrane to a solute does not appear to show a high dependence on the molecular weight of said solute (Finkelstein 1976). The lipid-water partition coefficient, on the other hand, does affect the ease and speed at which molecules cross the cell membrane. It is a measure of the solubility difference of a particular solute between the two immiscible phases of lipid and water; a coefficient equal to less than 1 means a greater amount...

...Running head: PROBLEM SOLUTION: GLOBAL COMMUNICATIONS Problem Solution: Global Communications John Doe University of Phoenix Problem Solution: Global Communications Problem-based learning allows the student to develop his or her problem-solving skills by applying them to an authentic scenario that requires them to identify a problem, apply a problem-solving approach to develop and analyze alternative solutions, and recommend and defend an optimal solution (University of Phoenix, 2010, para. 2). The Global Communications (GC) scenario identifies several issues for the student to analyze and solve using the lessons learned from the course. This paper identifies the major issues that GC is facing. These issues will be analyzed and the perspectives and ethical dilemmas of the stakeholders will be identified. An examination of the problem statement will reveal what improvements GC would like to see in three years. Alternate solutions will be presented and analyzed for validity. An appropriate risk will be assessed on the selected solutions and mitigation techniques explored. From this evaluation an optimal solution will be selected and a plan to implement explored.

...Solution Focused Therapy for Children Rhonda Kendrick December 11, 2014 Solution-focused therapy has a unique orientation toward non-problem times. The purpose is to help people target and amplify resources and strengths toward change (Berg, 1994). The article that I researched is about a study of using the framework of solution focused therapy with children. Children were referred by the study for presenting problems involved those relating to “behavior,” such as aggression toward peers or parents, defiance toward teachers, and conduct problems in school (i.e. non-completion of assignments, impulsivity, talking out-of-turn, and other classroom management problems). Referrals were screened out if they reported the need for treatment due to stressful life events, such as sexual abuse or if the child’s family had recently suffered a death or divorce. In the counseling session of the children, the counselors ask them questions concerning what helped them in the past with their problem. The questions asked by the counselors were usually focused on the present or on the future. That reflected on the basic belief that problems are best solved by focusing on what is already working, and how a client would like their life to be, rather than focusing on the past and what isn’t wanted. According to Nunnally (1993), “validating what clients are already doing well, and acknowledging how difficult their problems are encourages the client to change while giving the message that the...

... it increases the water movement out of the plant by a process called transpiration. When there is a shortage of water, the guard cells well get smaller and close the stomata, and the transpiration process will move slower. The osmolarity would be tested with solute concentrations ranging from 0.0 M to 0.6 M. The concentrations increased 0.1 M each time and the solute used was sucrose. The goal of this experiment was to determine which concentration had the least effect on the potato after being incubated. This information helped us estimate the osmolarity of the potato tuber tissue. Our group hypothesis is that the osmolarity of the potato will have the concentration with the 0.1 M solution. This hypothesis is based off the predicted outcome that smaller molarity concentrations will have the least effect on the potato. The more solute added to a solution decreases the concentration of water in most cases (Kosinski). The decrease in water concentration would then lead to a lower weight of the potato tuber once it has finished incubating. Methods & Materials: For experiment A you will need the following items: 1 large potato tuber Forceps petri dish razor blade DI water metric ruler 7 250 mL beakers/ or disposable cups balance that weighs to the nearest 0.01g sucrose...

...The data solute concentration of the egg was found by taking the average percent change in mass for each percent solute concentration used in the lab and putting the data into the graph(Mass vs. Solute Concentration Over 3 Days). According to the data from the class, the solute concentration inside an egg is 25.1%. The egg would be in an isotonic solution at 25.1% solute concentration. This is when the concentration outside the egg is equal with the concentration of water inside the egg. The point of equilibrium is the point at which the trendline crosses the x-axis. At this point, the egg would no longer gain or lose mass. If the concentrations are the same inside and outside the egg, diffusion will not be able to take place. All averages...

...FUNDAMENTALS OF SURFACE MODES: ¥ COLLOIDS ¥ means ÒglueÓ in Greek ¥ was coined in 1861 by Thomas Graham. ¥ ¥ ¥ ¥ ¥ WHAT IS A COLLOID? usually consists of two phases; one continuous phase in which the other phase is dispersed. Size of particles: larger than the size of molecules and small enough for the dispersed phase to stay suspended for a longer period of time. ¥ No strict boundaries for the size limits. OFFICIAL DEFINITION ¥ In 1903 Wolfgang Ostwald formulated the official definition of a colloid: ¥ a system containing entities having at least one length scale in between 1nm and 1µm. ¥ For smaller particles there is no distinct boundaries between the phases and the system is considered a solution; ¥ for larger entities the particles will fall to the bottom due to the gravitational force, and the phases are separated. 1 2 3 MESOSCOPIC PHYSICS ¥ The particle size is in the so-called mesoscopic range in between the macroscopic and microscopic limits. LARGE INTERFACIAL AREA ¥ One very important quality of the colloids is the large interfacial area between the dispersed and the continuous phases. WHAT EFFECTS HAS THIS? ¥ This means that interface effects and hence the electromagnetic surface modes, are very important for the properties of the colloids. ¥ It costs energy to create this much surface and the particles would clump together if this isnÕt prevented. ¥ Usually the particles are charged and hence repel each other. 5 6 4 Four states...

...Book Review 1 – ‘Children’s Solution Work’ by Insoo Kim Berg & Therese Steiner I chose to do my first book review of the year on ‘Children’s solution work’, as I was intrigued as to how this modality can be applied to children. My practice to date involves only adults so I am very keen to adopt tools and tips to effectively talk to children in a therapeutic way. I was definitely not disappointed! This book clearly demonstrated how the Solution-Focused Brief Therapy (SFBT) model can be applied to the nonverbal, playful and creative habits of children. The books extensive use of examples and case studies in various contexts and situations was instrumental in demonstrating the creative techniques and strategies for working with children without relying exclusively on language. I will use this book review to discuss some of the ideas, techniques and cases that really stood out for me with the hope that I may one day incorporate them into my clinical work. “There is good harmony between SFBT and children because there are so many similarities between how children think and make sense of the world around them and the assumptions and procedures of SFBT.” One excellent example of this is the child’s relative indifference to the “cause” of a problem, over their need/desire to “fix” it. I encounter this on a daily basis with my own children. I often find myself inquiring about the cause of their problems, feeling that by doing so I will gain greater insight into their thoughts...

...------------------------------------------------- Soil EC and pH using 3 types of extractant solutions on different soil samples ------------------------------------------------- Ben Vincent ------------------------------------------------- AGR2IlS subject coordinator: Dr Gary Clack ------------------------------------------------- INTRODUCTION ------------------------------------------------- pH is in general terms the about the acidity or alkalinity in a soil or growing medium, technically pH refers to the ratio concentration of H+ ions to OH- ions in a medium (Handreck & Black 1984) and given in the formula pH= Log10(H=). Considering H2O is neutral the pH will be lower if the concentration of H+ is higher and vice versa. The pH is important because it will determine the availability of nutrients to plants, amounts of nutrients held in soil, toxicities in soil and life of microorganisms (Handreck & Black 1984). Dramatic changes in a soils pH will cause stress to life that is held within it, this is where the desirable ability of pH buffering plays its role. This pH buffering is the ability of a soil to resist dramatic changes to pH levels in order to avoid plant stress (Handreck & Black 1984). Measurement of pH is one of the first and most important tests done on a soil, however there can be a variety of difficulties as in nature and agriculture not everything is in a standard condition. There can be large differences that affect the data recorded with...
