How do scientists study ecosystems and grapple with real-world conservation questions?


Learn about ecology and ecosystem dynamics using a systems thinking lens. Authored by world-class experts at the cutting edge of conservation biology, this six-week online course examines how scientists study various ecosystems around the world—from Mozambique's Gorongosa National Park, to the Hudson River in New York, to Caribbean coral reefs. Learners will investigate the complex array of factors that inform management efforts, and grapple with real-world conservation questions, such as whether an ecosystem can recover from disruption and what role humans can, and should, play in that recovery.

School performance, social networking effects, and learning of school children
Abstract

This study uses structural equations modeling to test a hypothetical social network model with applications to a sample of 34,896 school children in Abu Dhabi. The main independent constructs in the model are related to children’s attitude with regard to social networking, reasons for using social networks, things done on social networks, and topics used. The dependent constructs cover perceived school performance and social effects of social networking. The study will describe the relations among the various constructs. The effect of other variables, such as parental knowhow, is also investigated. Our work has improved our insight in the social networking model. Results support the idea of reciprocal relations among perceived performance, learning from social networking, and the effect of social networking. Evidence for a model that includes opposite pathways implies that the problem of social networking constructs, its antecedents, and possible consequences should be examined with caution.

The culture of the classroom can either support or create barriers to student success (Piffner,2011). Factors that foster attention, positive behavior, and academic and social success includeestablishing positive relationships with students, adopting classroom management techniques,and creating a physical arrangement that facilitates learning.
It is often a positive relationship with one teacher that facilitates school success for a studentwith ADHD (Piffner, 2011).

The world has changed dramatically in the three months since our last update of the World Economic Outlook in January. A rare disaster, a coronavirus pandemic, has resulted in a tragically large number of human lives being lost. As countries implement necessary quarantines and social distancing practices to contain the pandemic, the world has been put in a Great Lockdown. The magnitude and speed of collapse in activity that has followed is unlike anything experienced in our lifetimes.'

ABSTRACT: This paper attempts to show the main aspects which have given evolution to the development of a device belonging to a new pedagogic strategy called educational robotics. We present how starting from the basic design requirements expressed, and after applying a rigorous and methodological design process, the design specifications are obtained according to the different pedagogical, functional, esthetic, constructive, and economic aspects which this strategy proposes to implement.
KEYWORDS: Robotics, active learning, design methodology, innovation in education, engineering, artificial intelligence.
RESUMEN: Este artículo pretende mostrar los aspectos más relevantes en el desarrollo evolutivo del diseño de un dispositivo perteneciente a una nueva estrategia pedagógica denominada Robótica Educativa. Aquí se presenta cómo a partir de los requerimientos básicos de diseño expresados, y luego de aplicar un proceso riguroso y metodológico de diseño, se logra obtener las especificaciones de diseño acordes con los diferentes aspectos pedagógicos, funcionales, estéticos, constructivos y económicos que esta nueva estrategia de enseñanza propone implementar.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Depending on the subject or assignment, you could describe the person's physical appearance, behaviour, inner thoughts or the influence the person had on you or others. A person's appearance can be described in many ways.

polite (Please be polite to our guests.)
friendly (Everyone was very friendly towards me.)
honest (He was a hard-working honest man.)
generous (She's always very generous to the kids.)
rude (She was very rude about my driving.)
lazy (He is the laziest boy in the class.)

Lemon juice in its natural state is acidic with a pH of about 2, but once metabolized it actually becomes alkaline with a pH well above 7. So, outside the body, anyone can see that lemon juice is very acidic. However, once fully digested, its effect is proven to be alkalizing with many health benefits.
