Genetic Accommodation

Abstract Heyes argues that human metacognitive strategies (cognitive gadgets) evolved through cultural rather than genetic evolution. Although we agree that increased plasticity is the hallmark of human metacognition, we suggest cognitive malleability required the genetic accommodation of gadget-specific processes that enhanced the overall cognitive flexibility of humans.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).

Classroom Action Research

This research is motivated by the low interest students learning civics class II SDN 015 Pagaran Tapah Darussalam. Goals to be achieved in this research is to improve the interest in learning civics grade II SDN 015 Pagaran Tapah Darussalam through the use media pictures conducted during one month. This research was conducted in SDN 015 Pagaran Tapah Darussalam. Classes are meticulous researcher is a class II half of the number of students as many as 20 people. This classroom action research was started in early august 2015. This form of research is classroom action research. The research instrument consists of instruments teacher and student activity sheets and achievement test. Based on the analysis and discussion can be concluded that the success of the study is known of improving learning at each meeting for each cycle. The first cycle of the first meeting of student interests is still considered low by percentage of 48.3%. The first meeting of the second cycle increased with the percentage of 58,3%, in the first meeting of the second cycle also increases with the percentage of 70,8%, student interest in the percentage reached 80,00% or higher category. Thus the research hypothesis that says the use of media images can increase increase student interest in learning civics class II SDN 015 Pagaran Tapah Darussalam "unacceptable"

The One

Using as the example of the pilgrimage to Sabarimala (Kerala, South India), I propose here to explore the links existing between sources, research hypothesis and research theory in social sciences. The choice of research materials in the process of investigation, sources of knowledge about the studied object, is not mere random sampling; it is processed in accordance with the questions of the researcher. It inevitably assumes a selective dimension. After a critical reading of the sources used by Indian studies, I will highlight on the connections between the sources and the methodological tools on the one hand, and the major research hypothesis about pilgrimage on the other. The links between the data taken from the field and the legitimacy of scientific discourse on India will be examined at the end before providing some keys for the interpretation of Sabarimala phenomenon in South India during the contemporary period.

AbstrakPenelitian ini bertujuan untuk mengetahui Pengaruh Harga dan Brand Trust Terhadap Keputusan Pembelian pada Sinergy Celular Medan.Sampel dalam penelitian ini adalah seluruh pengunjung Sinergy Celular Medan sebanyak 77 orang.Teknik pengumpulan data yang digunakan adalah melalui kuesioner (angket) yaitu dengan cara menyebarkan kuesioner kepada sampel (responden) dan mengumpulkannya kembali. Teknik analisis data yang digunakan adalah Regresi Linear Berganda.Sebelum data diregresikan maka terlebih dahulu di uji keterkaitannya antara variabel, datanya diuji menggunakan uji normalitas data, multikolinearitas, dan heterokedastisitas.Serta untuk mengetahui kontribusi faktor Harga dan Brand TrustTerhadap Keputusan Pembelian digunakan rumus Koefisien Determinasi (R2). Hipotesis penelitian diterima apabila t hitung >  t tabel dengan tingkat signifikansi 0,1. Nilai t tabel dalam penelitian ini 1,993. Nilai t hitung variabel X1 sebesar 2,107 t hitung lebih besar dari t tabel maka hipotesis di terima, nilai t hitung variabel X2   sebesar 3,405 t hitung lebih besar dari t tabel maka hipotesis di terima. Kata kunci: Harga, Brand Trust, Keputusan Pembelian AbstractThis study aims to determine the Influence of Price and Brand Trust on Purchasing Decision at Sinergy Celular Medan. The sample in this study is all visitors Sinergy Celular Medan as many as 77 people.Data collection technique used is through questionnaire (questionnaire) that is by distributing questionnaires to the sample (respondent) and collect it back. Data analysis technique used is Multiple Linear Regression. Before the data is diregresikan then first in the test the relationship between variables, the data tested using the test of data normality, multicollinearity, and heterokedastisitas. And to know the contribution of price factors and Brand Trust Against Purchase Decision is used the formula Coefficient of Determination (R2). Research hypothesis accepted if t arithmetic> t table with significance level 0,1. The value of t table in this study is 1,993. Value t arithmetic variable X1 of 2.107 t arithmetic greater than t table then the hypothesis received, the value of t arithmetic variable X2 of 3.405 t arithmetic greater than t table then the hypothesis received. Keywords: Price, Brand Trust, Purchase Decision
