Mathematical connection ability is one of the abilities needed in solving mathematical problems. In solving problems, each student has a different way of solving it. This is due to the variety of intelligence that the students possess. This intelligence is known as Adversity Quotient (AQ). There are three levels of AQ namely climbers, campers, and quitters. This study aimed to describe the students' mathematical connections ability in solving mathematical problems related to their AQ. This research is a descriptive study with a qualitative approach carried out in Class IX of MTs Negeri Gresik consisting of three students who have different levels of AQ. The research instrument used consisted of the Adversity Response Profile (ARP) questionnaire, problem solving Test, and interview guidelines. The results of this study indicate that: at the stage of understanding the problem, climbers and campers students could retell with their language different from quitters students who change the language of questions with different meanings, at the stage of preparing a plan, climbers students understand the relationship of problems with mathematical concepts and life everyday and plan quite coherently and clearly while students campers and quitters understand the relationship of problems with mathematical concepts and everyday life and plan quite well, at the stage of implementing the plan, climbers and campers students could find the right answers while students quitters find the answers that are not yet correct, in the stage of looking back, climbers students do the checking again so that they could give the right conclusions while the campers and quitters students do not do the checks again but could provide conclusions that are quite precise.

Problem-solving and mathematical connections are two important things in learning mathematics, namely as the goal of learning mathematics. However, it is unfortunate that the ability of students 'mathematical connections is very low so that it impacts on students' failure in solving mathematical problems. The writing of this paper aims to discuss the understanding of mathematical problems, mathematical problem solving, mathematical connections, and how they play a role in solving mathematical problems. The method used in writing this paper is a method of studying literature, which is reinforced by the example of a qualitative research result. The research subjects consisted of two eighth grade students of junior high school in Jember East Java, Indonesia, in 2017/2018. The research data consisted of written test results solving the mathematical problem as well as interview results. Data analysis uses descriptive qualitative analysis. From the results of literature studies and research results provide a conclusion that mathematical connections play an important role, namely as a tool for students to use in solving mathematical problems where students who have good mathematical connection skills succeed in solving mathematical problems well, while poor mathematical connection skills cause students to fail in solving mathematical problems.

AbstractHans Kelsen is known both as a legal theorist and as an international lawyer. This article shows that his theory of international law is an integral part of the Kelsenian Pure Theory of Law. Two areas of international law are analysed: first, Kelsen's coercive order paradigm and its relationship to the bellum iustum doctrine; second, the Kelsenian notion of the unity of all law vis-à-vis theories of the relationship of international and municipal law. In a second step, the results of Kelsenian general legal theory of the late period – as interpreted and developed by the present author – are reapplied to selected doctrines of international law. Thus is the coercive order paradigm resolved, the unity of law dissolved, and the UN Charter reinterpreted to show that the concretization of norms as positive international law cannot be unmade by a scholarship usurping the right to make law.

The Survey of Consumer Finances (SCF) has included a 4-level risk tolerance measure since 1983. In 2016, the SCF also included an 11-level risk tolerance measure. We compare the two measures, and develop suggestions for using the new measure. While the new measure is seemingly simpler than the old measure, we demonstrate that it does not have a monotonic relationship with owning stock assets, with a pattern similar to the relationship of the old measure to stock ownership. We also identify complex patterns of factors related to different levels of the new measure, for instance education has a negative relationship at one level but positive at another level. Those using the new measure should consider the complex patterns we demonstrate.

Eccentric Actions

The speed-torque relationship of the right knee extensor muscle group was investigated in eight untrained subjects (28 +/- 2 yr old). Torque was measured at a specific knee angle during isokinetic concentric or eccentric actions at nine angular velocities (0.17-3.66 rad/s) and during isometric actions. Activation was by "maximal" voluntary effort or by transcutaneous tetanic electrical stimulation that induced an isometric torque equal to 60% (STIM 1) or 45% (STIM 2) of the voluntary isometric value. Torque increased (P less than 0.05) to 1.4 times isometric as the speed of eccentric actions increased to 1.57 rad/s for STIM 1 and STIM 2. Thereafter, increases in eccentric speed did not further increase torque. Torque did not increase (P greater than 0.05) above isometric for voluntary eccentric actions. As the speed of concentric actions increased from 0.00 to 3.66 rad/s, torque decreased (P less than 0.05) more (P less than 0.05) for both STIM 1 and STIM 2 (two-thirds) than for voluntary activation (one-half). As a result of these responses, torque changed three times as much (P less than 0.05) across speeds of concentric and eccentric actions with artificial (3.4-fold) than voluntary (1.1-fold) activation. The results indicate that with artificial activation the normalized speed-torque relationship of the knee extensors in situ is remarkably similar to that of isolated muscle. The relationship for voluntary activation, in contrast, suggests that the ability of the central nervous system to activate the knee extensors during maximal efforts depends on the speed and type of muscle action performed.
