How to be a successful app developer: lessons from the simulation of an app ecosystem
Soo Ling Lim, Peter J. Bentley
Abstract
App developers are constantly competing against each other to win more downloads for their apps. With hundreds of thousands of apps in these online stores, what strategy should a developer use to be successful? Should they innovate, make many similar apps, optimize their own apps or just copy the apps of others? Looking more deeply, how does a complex app ecosystem perform when developers choose to use different strategies? This paper investigates these questions using AppEco, the first Artificial Life model of mobile application ecosystems. In AppEco, developer agents build and upload apps to the app store; user agents browse the store and download the apps. A distinguishing feature of AppEco is the explicit modelling of apps as artefacts. In this work we use AppEco to simulate Apple's iOS app ecosystem and investigate common developer strategies, evaluating them in terms of downloads received, app diversity, and adoption rate.

POLITICAL POLLS
Despite their popularity, political polls, often seen on TV during elections, sometimes give _______1 results, and some Americans question their _______ 2 .
_______ 3 both 2016 and 2020, most national polls overestimated support for Democrats. Polls aim to show what people think at a certain time but can be tricky to predict future outcomes accurately.
Mallory Newall explains that reliable polls focus on understanding public opinions rather than just predicting election winners. She warns _______4 reading too much into small differences in polls, especially far _______5 election day. Red flags for bad polls include _______6 the right people and not being clear about how the data was collected.

Diversity and Inclusive Teaching
Teaching to engage diversity, to include all learners, and to seek equity is essential for preparing civically engaged adults and for creating a campus and society that recognizes the contributions of all people. Teaching for diversity refers to acknowledging a range of differences in the classroom. Teaching for inclusion signifies embracing difference. Teaching for equity allows the differences to transform the way we think, teach, learn and act such that all experiences and ways of being are handled with fairness and justice. These ideas complement each other and enhance educational opportunities for all students when simultaneously engaged. […]
Inclusive teaching strategies are intended to ensure that all students feel supported such that they freely learn and explore new ideas, feel safe to express their views in a civil manner, and are respected as individuals and members of groups. Intentionally incorporating inclusive teaching strategies helps students view themselves as people who belong to the community of learners in a classroom and university.

The BNCC and Twenty-First Century Skills
The most ambitious feature of the BNCC, which only appeared in the document’s third version, was to establish ten core competencies that all students should develop throughout basic education, starting in early childhood. These competencies include lifelong learning, critical thinking, aesthetic sensibilities, communication skills, digital literacy, entrepreneurship, self-care, empathy, citizenship and ethics. The core competencies broaden the goals of basic education well-beyond academic skills to twenty-first century skills widely regarded as essential to preparing the next generations for the challenges of the 4th industrial revolution.
As ambitious as it was, the BNCC was criticized for the lack of explicit links between the ten core competencies and the subject specific competencies and skills, leaving cities and states with the responsibility of making these links themselves. In addition to this, the core competencies are not generally integrated into teacher training programs and are often de-prioritized for the more basic literacy and numeracy needs. In this context, the Ministry of Education and its partners in the third sector have developed orientations, produced videos and online courses aimed at filling this gap, and helped cities and states integrate the ten core competencies in their curricula.
[…]
Ensuring all Brazilian students master the ten core competencies laid out by the BNCC by the end of high school is a long-term, extremely ambitious goal. Before we can set a timeframe for when we will be able to achieve this feat, we need to know where we stand. Due to the core competencies’ complexity, each involves several skills, attitudes and sometimes values, it is unclear whether we will be capable of measuring all ten of them and by when. Until then we are in the company of the OECD, which is already tackling this challenge and will likely pave the way for Brazil in this respect

Why is music good for the brain?
October 7, 2020
By Andrew E. Budson, MD, Editorial Advisory Board Member, Harvard Health Publishing
1. Can music really affect your well-being, learning, cognitive function, quality of life, and even happiness? Hand in a recent survey on music and brain health conducted by AARP revealed some interesting findings about the impact of music on cognitive and emotional well-being: music listeners had higher scores for mental well-being and slightly reduced levels of anxiety and depression compared to people overall.
2. Of survey respondents who currently go to musical performances, 69% rated their brain health as “excellent” or “very good,” compared to 58% for those who went in the past and 52% for those who never attended. Of those who reported often being exposed to music as a child, 68% rated their ability to learn new things as “excellent” or “very good,” compared to 50% of those who were not exposed to music.
3. Active musical engagement, including those over age 50, was associated with higher rates of happiness and good cognitive function. Adults with no early music exposure but who currently engage in some music appreciation show above average mental well-being scores. Those are pretty impressive results, to be sure. However, this 20-minute online survey has some limitations. For one, it included 3,185 US adults ages 18 and older; that is a small number if you are extrapolating to 328 million people across the country. For another, it is really a survey of people’s opinions. For example, although people might report their brain health as “excellent,” there was no objective measure of brain health such as an MRI scan, or even a test to measure their cognition.
4. Lastly, even if the ratings were true, the findings are only correlations. They do not prove that, for example, it was the exposure to music as a child that led to one’s improved ability to learn new things. It may be equally likely that those children brought up in more affluent households were both more likely to be exposed to music and to be given a good education that led to their being able to easily learn new things later in life.
5. Music has been shown to activate some of the broadest and most diverse networks of the brain. Of course, music activates the auditory cortex in the temporal lobes close to your ears, but that’s just the beginning. The parts of the brain involved in emotion are not only activated during emotional music, they are also synchronized. Music also activates a variety of memory regions. And, interestingly, music activates the motor system. In fact, it has been theorized that it is the activation of the brain’s motor system that allows us to pick out the beat of the music even before we start tapping our foot to it!
6. Okay, get along! so music activates just about all of the brain. Why is that so important? Well, have you ever heard the expression, “If you don’t use it, you’ll lose it”? It turns out this is actually true in the brain. Brain pathways — and even whole networks — are strengthened when they are used and are weakened when they are not used. The reason is that the brain is efficient; it isn’t going to bother keeping a brain pathway strong when it hasn’t been used in many years. The brain will use the neurons in that pathway for something else. These types of changes should be intuitively obvious to you — that’s why it is harder to speak that foreign language if you haven’t used it in 20 years; many of the old pathways have degraded and the neurons are being used for other purposes.
