AbstractResearchers dissatisfied with the performance of the Beverton-Holt model, in contexts where “Beverton-Holt-like” behavior is expected, have introduced a plethora of alternative model forms. This paper presents a formalization of what constitutes “Beverton-Holt-like behavior” which includes many of these forms, and shows that the class of functions so defined has a coherent and non-trivial mathematical theory. Data from the stock production database assembled by Ransom Myers is used to illustrate why such generalizations have been sought in the first place, and to highlight the difficulties in choosing between model forms on purely empirical grounds. Special attention is given to a parametric family of functions within this class, here called “θ-BH” functions. These functions cover a broad range of shapes, including both the Beverton-Holt and hockey stick functions, and share useful properties with these two widely-used models.

Realist Perspective

The author elaborates on methodological issues of current tendencies in neoclassical theory and demonstrates the necessity of an alternative model of science, which he calls "realist". According to this perspective, constant and regular conjunctions of economic life events should not be the main object of analysis. Rather, the author proposes to consider structures and mechanisms governing events in question. Instead of deductivism, which, as Lawson believes, is a fundamental feature of orthodox economics, the abductive method of economic explanation is proposed that entails investigation of major powers, on which any social phenomenon depends. Society is thereby regarded not as a closed, but rather as an open system.

Class Of Functions

In this work a class of functions is studied, which are built with the help of significant bits sequences on the ring ℤ2n. This class is built with use of a function ψ: ℤ2n → ℤ2. In public literature there are works in which ψ is a linear function. Here we will use a non-linear ψ function for this set. It is known that the period of a polynomial F in the ring ℤ2n is equal to T(mod 2)2α, where α∈ , n01- . The polynomials for which it is true that T(F) = T(F mod 2), in other words α = 0, are called marked polynomials. For our class we are going to use a polynomial with a maximum period as the characteristic polyomial. In the present work we show the bounds of the given class: non-linearity, the weight of the functions, the Hamming distance between functions. The Hamming distance between these functions and functions of other known classes is also given.

Interreligious Education

Some circles suggest that the phenomenon of intolerance and religious conflict in Indonesia will be reduced by a religious education model dominated by a mono-religious approach. The approach that focuses on deepening the knowledge of all religions is considered to be the cause of the persistence of interfaith stigma and prejudice. However, there are objections from various circles to the concept and application of interreligious education which requires close dialogue and interaction, an appreciative attitude, and openness to adherents of other religions. This article argues that the development of a peaceful and diverse mono-religious education approach is possible. This study employs Mohammed Abu-Nimer's theory as an alternative model of Islamic peace education that is strategic, participatory and practical; it focuses on his experience in conflict areas and in the Islamic education environment, which is often stigmatized conservatively in the Middle East and Africa. This study confirms that monoreligious education provides room for peace education that builds pedagogy of tolerance, diversity and human rights.
