Convergent Evolution in Stone-Tool Technology
Scholars from a variety of disciplines consider cases of convergence in lithic technology, when functional or developmental constraints result in similar forms in independent lineages. Hominins began using stone tools at least 2.6 million years ago, perhaps even 3.4 million years ago.Given the nearly ubiquitous use of stone tools by humans and their ancestors, the study of lithic technology offers an important line of inquiry into questions of evolution and behavior.This book examines convergence in stone tool-making, cases in which functional or developmental constraints result in similar forms in independent lineages.Identifying examples of convergence, and distinguishing convergence from divergence, refutes hypotheses that suggest physical or cultural connection between far-flung prehistoric toolmakers.Employing phylogenetic analysis and stone-tool replication, the contributors show that similarity of tools can be caused by such common constraints as the fracture properties of stone or adaptive challenges rather than such unlikely phenomena as migration of toolmakers over an Arctic ice shelf.

Grupo Clarin : From Argentine Newspaper to Convergent Media Conglomerate
From its emergence as a modest newspaper to becoming the largest communication group in Argentina, and one of the main communications groups in Latin America, this book examines the media conglomerate Grupo Clarín. Guillermo Mastrini, Martín Becerra and Ana Bizberge analyze the group’s corporate structure and the aspects that have contributed to its expansion throughout its history, mapping its stages of growth to the regulatory policies, cultural politics, economics and political history of Argentina over the last few decades.This book offers a compelling analysis of one of the key players in the Latin American communication and information market, highlighting how the conglomerate has continued to grow under various different governments - by achieving legal reforms and influencing policies - and continues to have great capacity to influence the policy and regulation of the system, the market structure and cultural consumption in the region. This book is ideal for students, scholars and researchers of global media, political economy, and media and communication, especially those with an interest in Latin America.

What are convergent series and what are absolutely convergent series?
A convergent series is a series of numbers that has a finite sum. In other words, as you add up more and more terms of the series, the sum approaches a specific value. On the other hand, an absolutely convergent series is a series in which the absolute values of the terms converge to a finite sum. In other words, the series converges when you take the absolute value of each term and then add them up. Absolutely convergent series have the property that rearranging the terms does not change the sum, while for convergent series, rearranging the terms can change the sum.

Is the product of two convergent sequences always a convergent sequence?
No, the product of two convergent sequences is not always a convergent sequence. While the product of two convergent sequences may converge, it is not guaranteed. This is because the convergence of a product of sequences depends on the behavior of the individual sequences and their interaction with each other. Therefore, it is possible for the product of two convergent sequences to be divergent.
-
Is the series convergent?
To determine if a series is convergent, we need to analyze the behavior of its terms as the number of terms approaches infinity. If the terms of the series approach a finite value as the number of terms increases, then the series is convergent. On the other hand, if the terms do not approach a finite value, the series is divergent.
-
Is the series a convergent if b is a convergent positive sequence?
Yes, if b is a convergent positive sequence, then the series Σb_n will also be convergent. This is because the convergence of the sequence b_n implies that the terms of the sequence approach a finite limit as n goes to infinity. As a result, the terms of the series Σb_n will also approach zero, and the series will converge. Therefore, the convergence of the sequence b_n guarantees the convergence of the series Σb_n.

The Divergent and Convergent Thinking Notebook : Notebook for Creative Thinking
Creativity research shows that dividing thinking into divergent and convergent forms improves and increases idea production; this leads to unexpected thoughts and original solutions.Divergent thinking is used to generate ideas; convergent thinking helps in selecting the best ideas. The concept of divergent and convergent thinking is so integral to the creative process and innovative thinking that it is known as ‘the heartbeat of creativity’.It is the underlying rhythm of creative thinking. This book is an introduction to divergent and convergent thinking and includes guidelines to enhance innovative thinking, as well as hands-on exercises to strengthen creativity. The concept of the book is supported by its triangular shape, illustrating divergent and convergent thinking: the top half of the book communicates divergent thinking, while the bottom half communicates convergent thinking.This principle remains the same throughout the book.

Convergent Evolution on Earth : Lessons for the Search for Extraterrestrial Life
An analysis of patterns of convergent evolution on Earth that suggests where we might look for similar convergent forms on other planets. Why does a sea lily look like a palm tree? And why is a sea lily called a "lily" when it is a marine animal and not a plant?Many marine animals bear a noticeable similarity in form to land-dwelling plants. And yet these marine animal forms evolved in the oceans first; land plants independently and convergently evolved similar forms much later in geologic time.In this book, George McGhee analyzes patterns of convergent evolution on Earth and argues that these patterns offer lessons for the search for life elsewhere in the universe. Our Earth is a water world; 71 percent of the earth's surface is covered by water.The fossil record shows that multicellular life on dry land is a new phenomenon; for the vast majority of the earth's history-3,500 million years of its 4,560 million years of existence-complex life existed only in the oceans.Explaining that convergent biological evolution occurs because of limited evolutionary pathways, McGhee examines examples of convergent evolution in forms of feeding, immobility and mobility, defense, and organ systems.McGhee suggests that the patterns of convergent evolution that we see in our own water world indicate the potential for similar convergent forms in other water worlds.We should search for extraterrestrial life on water worlds, and for technological life on water worlds with continental landmasses.

Determine whether the following series are absolutely convergent, conditionally convergent, or divergent.
To determine whether a series is absolutely convergent, conditionally convergent, or divergent, we need to consider both the original series and the absolute value of the series. If the original series converges and the absolute value of the series also converges, then the series is absolutely convergent. If the original series converges but the absolute value of the series diverges, then the series is conditionally convergent. If the original series diverges, then the series is divergent.
-
Is the alternating sequence convergent?
No, the alternating sequence is not necessarily convergent. An alternating sequence is a sequence in which the terms alternate in sign. Whether or not the alternating sequence converges depends on the behavior of the terms in the sequence. If the terms in the sequence do not approach a specific value as n approaches infinity, then the alternating sequence is not convergent.
-
Is every convergent sequence monotonic?
No, not every convergent sequence is monotonic. A convergent sequence is one that approaches a specific limit as the number of terms in the sequence increases. A monotonic sequence, on the other hand, is one that is either always increasing or always decreasing. While some convergent sequences may be monotonic, there are also convergent sequences that oscillate or have a mix of increasing and decreasing terms as they approach their limit. Therefore, not every convergent sequence is monotonic.
-
What is the proof that a rearrangement of an absolutely convergent series is also convergent?
The proof that a rearrangement of an absolutely convergent series is also convergent lies in the fact that absolute convergence implies convergence. Since the series is absolutely convergent, we know that the sum of the absolute values of the terms converges. Therefore, no matter how we rearrange the terms, the rearranged series will still converge to the same sum as the original series. This is because the convergence of the rearranged series is guaranteed by the convergence of the absolute values of the terms.
