Mode Of Production

This article attempts to provide a breakthrough which I call mode of production theory. This theory will be employed to analyze the contemporary phenomenon of radical Islamism. The mode of production theory is meant to bridge the two clashing theoretical paradigms in social sciences and humanities, i.e., Weberian and Marxian. Despite its bridging nature, the paper argues that the two cannot be merged within one single thread. This is because each paradigm has its own epistemological basis which is irreconcilable to one another. Mostly adapted from Marx’s theory, the current theory of the mode of production covers five interrelated aspects, namely social, political, economic, cultural, and symbolic structures. If Marx’s mode of production theory heavily relies on a material and economic basis, the theory used in this paper accommodates cultural and symbolic structures that are Weberian in nature. Although the two paradigms can operate together, the strength of structure (Marxian) overpowers the strength of culture (Weberian). This paper further argues that such cultural-based aspects as ideology, norms, and values play as mobilizing factors under a big schematic dominant structure in the rise and development of the radical Islamist groups.

The lack of precision of measurements with alternate currents, as compared with those using direct currents, is mainly due to the relative sensitiveness of the instruments available for such tests. The fact that the turning moment acting on the moving system depends in one case on the square of the current and in the other on the first power of the current, readily explains the high ratio between the currents needed to cause the minimum measurable deflection in the two cases, but this ratio is, nevertheless, most striking when a numerical comparison is actually made on some fair basis. The only likely way at present of improving alternate current instruments is to use iron cored electromagnets to increase the strength of the magnetic field. I have found that the difficulties due to varying permeability and hysteresis of the iron can be avoided by exciting the electromagnet in shunt. It proves possible, with careful design, to construct an electromagnet whose flux is connected with the exciting voltage by a strict mathematical law involving no variable physical properties like permeability, etc. Such an electromagnet is eminently suited for measuring purposes. The theoretical and experimental study of instruments constructed on this principle has brought out certain novel points which are set forth in the present paper. The first part discusses the mathematical relations of cyclic quantities having a common fundamental period, and constitutes a development of a method already published. This method is the only one known to me which is independent of assumptions in regard to the wave form of the quantities dealt with. The usual methods, which are based on the erroneous assumptions of sine law wave form, are not any simpler in working, and are most unsatisfactory when the accuracy of new results has to be critically examined. All alternate current measurements refer to mean squares or to mean products, and the natural method of obtaining the connections between such squares and products is to study the properties of quadratic functions of the variables. The earliest instance of this in alternate current theory was in connection with the “three voltmeter method.” Such processes lead to a very simple form of calculus appropriate to cyclic quantities.

Male Care

Explaining the evolution of male care has proved difficult. Recent theory predicts that female promiscuity and sexual selection on males inherently disfavour male care. In sharp contrast to these expectations, male-only care is often found in species with high extra-pair paternity and striking variation in mating success, where current theory predicts female-only care. Using a model that examines the coevolution of male care, female care and female choice; I show that inter-sexual selection can drive the evolution of male care when females are able to bias mating or paternity towards parental males. Surprisingly, female choice for parental males allows male care to evolve despite low relatedness between the male and the offspring in his care. These results imply that predicting how sexual selection affects parental care evolution will require further understanding of why females, in many species, either do not prefer or cannot favour males that provide care.

The Relationship

There is no current theory that explains the process of a fathers’ bonding with their infants born prematurely. Through meta-synthesis of 19 qualitative studies, we developed a conceptual framework to illustrate how fathers perceive the relationship with their premature infant formed over the first 18 months of life. It details the contextual factors that contribute to that process. Findings reveal a complex process comprised of five stages, derived from five core themes and related subthemes. Fathers progress through five sequential stages to establish their role as fathers and form emotional connections with their child. Stages include: (a) feeling alien and lacking emotional connection to the infant, (b) caregiving engagement and claiming the role as a father, (c) claiming the infant as their own, (d) adjusting to having the infant home, and (5) normalizing family life. This conceptual framework can inform future research and clinical interventions designed to foster father−infant bonding.

Practical Implications

Purpose In the context of public-private partnerships (PPPs), it has been argued that the standard valuation framework produces a paradox whereby government appears to be made better off by taking on more systematic risk. This has led to a range of approaches being applied in practice, none of which are consistent with the standard valuation approach. The purpose of this paper is to demonstrate that these approaches are flawed and unnecessary. Design/methodology/approach The authors step through the proposed alternative valuation approaches and demonstrate their inconsistencies and illogical outcomes, using theory, logic and mathematical proof. Findings In this paper, the authors demonstrate that the proposed (alternative) approaches suffer from internal inconsistencies and produce illogical outcomes in some cases. The authors also show that there is no problem with the current accepted theory and that the apparent paradox is not the result of a deficiency in the current theory but is rather caused by its misapplication in practice. In particular, the authors show that the systematic risk of cash flows is frequently mis-estimated, and the correction of this error solves the apparent paradox. Practical implications Over the past 20 years, PPP activity around the globe amounts to many billions of dollars. Decisions on major infrastructure funding are of enormous social and economic importance. Originality/value To the best of the authors’ knowledge, this study is the first to demonstrate the flaws and internal inconsistencies with proposed valuation framework alternatives for the purposes of evaluating PPPs.

Research within Asian American psychology continually grows to include a range of topics that expand on the heterogeneity, hybridity, and multiplicity of the Asian American psychological experience. Still, research focused on distinct racialization and psychological processes of Asians in America is limited. To advance scientific knowledge on the study of race and racism in the lives of Asian Americans, we draw on Asian critical race theory and an Asian Americanist perspective that emphasizes the unique history of oppression, resilience, and resistance among Asian Americans. First, we discuss the rationale and significance of applying Asian critical race theory to Asian American psychology. Second, we review the racialized history of Asians in America, including the dissemination of essentialist stereotypes (e.g., perpetual foreigner, model minority, and sexual deviants) and the political formation of an Asian American racial identity beginning in the late 1960s. We emphasize that this history is inextricably linked to how race and racism is understood and studied today in Asian American psychology. Finally, we discuss the implications of Asian critical race theory and an Asian Americanist perspective to research within Asian American psychology and conclude with suggestions for future research to advance current theory and methodology.

Mixedwood forest composition, or co-dominance of hardwood and softwood species, has been interpreted as both stable and unstable. Through review of existing theory, we propose a conceptual model to understand mixedwood compositional stability in boreal and temperate forests of eastern North America. We first review the current theory that the strength of neighborhood effects (i.e. species ability to self-replace under their own canopy) is essential to understanding stability, such that when self-replacement is strong for both dominant hardwood and softwood species, composition is stable except at extreme disturbance severities. In contrast, when mixedwood forests are dominated by negligible or weak affinities to self-replace, composition is unstable and sensitive to changes in disturbance. Our new concept further posits that both change in the disturbance severity and in its vertical direction are essential to understanding stability. For example, where moderate-severity surface fires (which impact forests from below) cease and are replaced by moderate-severity blowdowns (which impact forests from above), instability can occur even when disturbance severity is unchanged. We therefore pose and discuss an extension to current theory to provide a new unifying concept of stability for mixedwood forests and, more broadly, for mixed-species forests.

The term "Neue Musik" was coined for a special concept of fundamental musical innovation within Austro-German music theory of the early 20th century, and it found no terminological equivalent beyond the German language. Established by Paul Bekker with his lecture “Neue Musik” in 1919, composers such as Stockhausen or Ligeti embraced the term with its emphatic claim to innovation and new departures. However, one hundred years on the term "Neue Musik" is often used mainly as a synonym for any type of contemporary music. This article questions whether the term "Neue Musik" is still an appropriate framework for a current theory of musical composition. Not only have the specific musical circumstances changed within the course of the 20th century, but also the political and social conditions have altered drastically after two world wars which had given special impulses to those composers who strove for a new foundation of music after 1918 and 1945 respectively. This article argues that the age of "Neue Musik" has come to an end in the late 20th century, and thus it is now necessary to introduce alternative terminological concepts and methodical directions for music historiography.
