"In the twentieth century, we humans began to transform our surroundings, our societies, and even ourselves. Without really intending to, we have introduced changes so rapid and so massive that our species has become the equivalent of a new geological force. That is why many scholars have begun to argue that planet Earth has entered a new…

We seek to understand how issues of intersectionality are addressed in environmental and sustainability education (ESE) literature, focusing on how gender is discussed in relation to other social identities such as class, race, sexuality, and ability. Our analysis draws from feminist and decolonizing frameworks, and uses intersectionality to…

Biases against the elderly and people with disabilities can lead to discriminatory behaviors. One way to conceptualize attitudes toward the elderly and people with disabilities is through the differentiation of explicit (conscious) and implicit (unconscious) factors. Although both explicit and implicit attitudes and biases contribute to the full…

In their role as careful observers of nature, citizen scientists are helping to "answer the most challenging ecological and environmental questions, addressing issues that affect everyday lives" (McKinley et al. 2015). They help answer these questions by providing scientists with a large pool of data that can be analyzed (National…

This research explores the impact of the Reading Education Assistance Dogs (READ) scheme on reading engagement and motivation among Early Years Foundation-Stage children using a case study approach at a primary school in the English Midlands. There is a notable lack of UK-based research into the READ scheme, which offers a potential alternative…

Imagine saving just one of the 23,000 species threatened with extinction. Students studying endangered species in a general life science course faced the decision of which species to save as a summative assignment in a unit on scientific explanation and argumentation. They used the claim, evidence, and reasoning (CER) framework in which students…

The purpose of this research was to explore and compare the ideas of Saudi boys and girls on animal species. Eighty-four children (comprising 42 boys and 42 girls), aged nine years, from four primary schools, participated in structured interviews to determine their ideas pertaining to taxonomic labels, namely 'animal', 'fish', 'amphibian',…

Lasting memories are likely to result from a lasting change in neurotransmission. In the nematode "Caenorhabditis elegans," spaced training with a tap stimulus induces habituation to the tap that lasts for greater than 24 h and is dependent on glutamate transmission, postsynaptic AMPA receptors, and CREB. Here we describe a distinct, presynaptic…

In "Aplysia," repeated trials of aversive stimuli produce long-term sensitization (LTS) of defensive reflexes and suppression of feeding. Whereas the cellular underpinnings of LTS have been characterized, the mechanisms of feeding suppression remained unknown. Here, we report that LTS training induced a long-term decrease in the excitability of…

Summation is the usual result in composition procedures with excitatory stimuli. However, summation is difficult to obtain in autoshaping with pigeons. The problems with this preparation have been related to the stimuli used: combinations of intramodal conditioned stimuli (CSs). During the perceptual processing of this type of stimuli, some mutual…

Although response-dependent shock often suppresses responding, response facilitation can occur. In two experiments, we examined the suppressive and facilitative effects of shock by manipulating shock intensity and the interresponse times that produced shock. Rats' lever presses were reinforced on a variable-interval 40-s schedule of food…

Purpose: To examine the perceived need for research on elements of successful service dog partnerships in the workplace outlined by stakeholders in an exploratory study. Method: A structured mixed methods approach was used to gather ideas from people with service dogs, trainers, vocational rehabilitation counselors, and other health care…

Encoding new information in the brain requires changes in synaptic strength. Neuromodulatory transmitters can facilitate synaptic plasticity by modifying the actions and expression of specific signaling cascades, transmitter receptors and their associated signaling complexes, genes, and effector proteins. One critical neuromodulator in the…

Four experiments used rats to study false context fear memories. In Experiment 1, rats were pre-exposed to a distinctive chamber (context A) or to a control environment (context C), shocked after a delay in a second chamber (context B) and tested either in B or A. Rats pre-exposed to A froze just as much as control rats in B but more than control…

Memory deficits are common among stroke survivors. Identifying neuroprotective agents that can prevent memory impairment or improve memory recovery is a vital area of research. Glycogen synthase kinase-3ß (GSK-3ß) is involved in several essential intracellular signaling pathways. Unlike many other kinases, GSK-3ß is active only when…
