No Peace in Our Time

Abstract

Forty young leaders were chosen to be profiled in this issue. In an effort to gain insight from them, they were each asked five questions: What are the major challenges for you as a young leader of the academy? What do you perceive as the major challenges ahead for higher education in the next two decades? Do you have a mentor(s), and if so, how has this helped you in your career? How are you learning to lead? What are your hopes for higher education in the next two decades?

From their responses several items emerged, including a great deal of concern about keeping higher education accessible and rethinking how learning can be prompted more widely. There was strong consensus that mentors had played a vital role in their development, and must continue to do so. Finally, there was strong agreement that preparation for national leadership required the opportunity to practice it, to make mistakes, to take risks, and to learn from their own “real world” choices.

The following profiles surely do not include all the young leaders of the academy, but this group clearly represents many of the strongest and the smartest. Our profound hope is that their numbers grow, as do their opportunities for learning through leading.     

A Plan for Problem Solving

<正>In mathematics,you often encounter some difficult problem.When solving math problems,it is often helpful to have an organized problem-solving plan.Today we will talk about"A Plan for Problem Solving"When solving math problems,the four steps listed below can be used to solve any problem.1.Explore·Read the problem carefully.·What facts do you know?·What do you need to find out?·Is enough information given?·Is there extra information?2.Plan·How do the facts relate to each other?·Plan a strategy for solving the problem.     

Understanding kindergarten teachers’ perspectives of teaching basic geometric shapes: a phenomenographic research

Geometry is one of the disciplines children involve within early years of their lives. However, there is not much information about geometry education in Turkish kindergarten classes. The current study aims to examine teachers’ perspectives on teaching geometry in kindergarten classes. The researchers inquired about teachers’ in-class experiences in geometry and asked a series of questions such as “what are the benchmarks in your kindergarten class?”; “what kind of tools and materials you use to teach geometry in your class?”; “what shape do you teach first in your kindergarten class?”; “what do you expect to hear when you asked your students ‘what is square’?”; “how do you teach rectangular?”. The study utilized one of the qualitative research methods, namely phenomenography, to collect the data and analyze the data. The study involved with eight kindergarten teachers who work in different schools in central Kutahya, Turkey. The researchers collected data by conducting face-to-face half-structured interviews. The findings of this phenomenographic research showed that kindergarten teachers have some difficulties in teaching geometry and have lack of knowledge and skills in teaching geometry in kindergarten classes.

Shortest Inspection Curves for the Sphere

What is the form of the shortest curve C going outside the unit sphere S in ?³ such that passing along C we can see all points of S from outside? How will the form of C change if we require that C has one (or both) of its endpoints on S? A solution to the latter problem also answers the following question. You are in a half-space at a unit distance from the boundary plane P, but you do not know where P is. What is the shortest space curve C such that going along C you will certainly come to P? Geometric arguments suggest that the required curves should be looked for in certain classes depending on several parameters. A computer-aided analysis yields the best curves in the classes. Some other questions are solved in a similar way. Bibliography: 4 titles.     

Nurses, surgeon not negligent in retained instrument suit. Kissinger v Turner

Instrument counts are controversial. Though they are recommended on all procedures by the Association of Operating Room Nurses, the majority of hospitals aren't doing them, according to a survey by OR Manager. What happens if you don't have a policy, an instrument is left in, and the case goes to court? What is the role of professional recommendations? The health care law firm of Horty, Springer & Mattern discusses just such a case.
