The Relationship

The relationship between visually and haptically derived representations of objects is an important question in multisensory processing and, increasingly, in mental representation. We review evidence for the format and properties of these representations, and address possible theoretical models. We explore the relevance of visual imagery processes and highlight areas for further research, including the neglected question of asymmetric performance in the visuo – haptic cross-modal memory paradigm. We conclude that the weight of evidence suggests the existence of a multisensory representation, spatial in format, and flexibly accessible by both bottom — up and top — down inputs, although efficient comparison between modality-specific representations cannot entirely be ruled out.

The Relationship

<p>Following the 2010 and 2011 Canterbury earthquakes, earthquake strengthening is one of the biggest issues facing heritage buildings in New Zealand. This process is mainly affecting commercial and public buildings; residential buildings are generally exempt from earthquake-prone building policies. However, some homeowners are choosing to do what is often perceived to be an expensive and time-consuming process. This research explores whether there is a heritage relationship between the homeowner and their house that motivates conservation work, such as earthquake strengthening. The central question for this research is: “What makes a heritage house a home? Is “home” a motivation for owners to earthquake strengthen their building? a case study of Dunedin”.  The relationship between homeowners and the heritage of their homes and domestic conservations practices has been underexamined in heritage studies in New Zealand. The current dissertation addresses this problem and contributes to the literature of Museum and Heritage Studies. The theoretical framework employed in this research draws on the field of Critical Heritage Studies in order to explore the relationship between ‘top-down’ and ‘bottom-up heritage’, the notion of ‘peoples-based’ heritage, the value of intangible heritage and a cycle of care. This research utilised qualitative research methods, involving the interviewing three heritage homeowners and two heritage professionals. These provided detailed findings about homeowners’ perceptions of their houses and the interaction between heritage practitioners and homeowners. The southern city of Dunedin was the case study which framed this research, because it has a rich collection of heritage buildings and a council which has been proactive in encouraging earthquake strengthening.  It was found that the heritage homeowner’s relationship with their home played a role in conservation how decisions are undertaken and that there is a lack of outreach from heritage authorities to heritage homeowners. This research provides information about the nature of the interaction between top-down and bottom-up heritage, and how this relationship can lead to positive heritage outcomes. Recommendations include developing open channels of communication between officials and homeowners, increased acknowledgement of the homeowner’s role in the conservation practice, and the establishment of a concept of Domestic Heritage to assist within the development of a cycle of care by heritage homeowners.</p>

The Relationship

An aspect of the relationship between philosophy and computer engineering is considered, with particular emphasis upon the design of artificial moral agents. Top-down vs. bottom-up approaches to ethical behavior are discussed, followed by an overview of some of the ways in which traditional ethics has informed robotics. Two macro-trends are then identified, one involving the evolution of moral consciousness in man and machine, the other involving the fading away of the boundary between the real and the virtual.

Wesley Salmon has suggested that the two leading views of scientific explanation, the “bottom-up” view and the “top-down” view, describe distinct types of explanation. In this paper, I focus on theoretical explanations in physics, i.e., explanations of physical laws. Using explanations of E=mc2, I argue that the distinction between bottom-up explanations (BUEs) and top-down explanations (BUEs) is best understood as a manifestation of a deeper distinction, found originally in Newton’s work, between two levels of theory. I use Einstein’s distinction between ‘principle’ and ‘constructive’ theories to argue that only lower level theories, i.e., ‘constructive’ theories, can yield BUEs. These explanations, furthermore, depend on higher level laws that receive only TDEs from a ‘principle’ theory. Thus, I conclude that Salmon’s challenge to characterize the relationship between the two types of explanation can be met only by recognizing the close relationship between types of theoretical explanation and the structure of physical theory.

The Relationship

Governments around the world are actively exploring strategies to reduce carbon emissions and mitigate and adapt to the impacts of climate change. In addition to technological progress, promoting a transformation of residents’ behaviors to a low carbon mode is also a solution. Many people are concerned about how to reduce carbon emissions while ensuring human well-being. Starting from the comparative analysis of two main theories of human well-being, this paper sorted out existing well-being measurement methods from the perspectives of “top-down” and “bottom-up” and further sorted out research on the relationship between human well-being and energy carbon emissions. While “top-down” research is conducive to the layout of macro policies, “bottom-up” research can better help to promote the transformation of society to a low carbon life by estimating the energy consumption and carbon emissions contained in human needs. Current research discusses human well-being, human needs, energy use and carbon emissions, respectively, but they are not systematically integrated. Furthermore, this paper proposes a framework combining these aspects to analyze the relationship between human well-being and carbon emissions. In addition, this paper suggests future research directions.

Point Of Departure

In this paper we will present a theoretical explanation of the relationship between so-called individual emergence and the emergence of social systems. We want to take as our point of departure the assumption that from the perspective of hierarchical systems theory self-organization on the level of social systems includes a bottom-up process as well as a top-down process. The bottom-up process refers to what in sociology is called agency, the top-down process refers to what is called structure. We will show that it is convenient to suggest that these processes be linked in a dialectical manner. In this respect we will discuss problems of determinism and indeterminism. This is the background against which we will try to clarify the notion of individual emergence. Our rather general considerations will be illustrated by how ideology, that is consciousness in a collective as well as an individual sense, is conceived of by a number of theories and how it should be conceived of when aspects of self-organization are included. We will conclude with a statement that makes clear why consciousness is a property of individuals that emerges only when individuals participate in society and why society emerges only when individuals are endowed with consciousness.

The Relationship

“Towards the end of the first decade of the twenty-first century”, as Anthony Gardner and Charles Green propose, “biennials became self-conscious.” Increasingly they are reflecting on themselves as "hegemonic machines" (Oliver Marchart), and for this very reason also understand themselves as places of intervention. We have to come to terms with the fact that biennials today are both: "Brands and Sites of Resistance", "Spaces of Capital and Hope" (Panos Kompatsiaris).The article follows withdrawals and protests as well as interventions and strategies of appropriation of biennials in the second decade of the 21st century. Protests in St. Petersburg, Sydney and New York shape the biennials they boycott. In Kochi, Athens, Dhaka, and Kassel we encounter curatorial projects that challenge the apparatus of value coding. The relationship between bottom up and top down often becomes blurred. In Prague, Warsaw, Kiev, and Budapest it is even reversed. Here biennials are used as a means of counter-hegemony and institutional survival.

Neural Representations

For decades, the extent to which visual imagery relies on similar neural mechanisms as visual perception has been a topic of debate. Here, we review recent neuroimaging studies comparing these two forms of visual experience. Their results suggest that there is large overlap in neural processing during perception and imagery: neural representations of imagined and perceived stimuli are similar in visual, parietal and frontal cortex. Furthermore, perception and imagery seem to rely on similar top-down connectivity. The most prominent difference is the absence of bottom-up processing during imagery. These findings fit well with the idea that imagery and perception rely on similar emulation or prediction processes.

Robust Evidence

Recent research has shown that observing others in pain leads to a general facilitation of reaction times. The current study sheds further light on the relationship between pain observation and reaction time by exploring how bottom-up processes, in the form of perceived pain intensity, and top-down processes, in the form of explicit instructions to empathize, influence response facilitation after pain observation. Participants watched videos of a hand getting pierced by a needle or touched by a Q-tip. To manipulate bottom-up information, participants saw videos depicting either deep or shallow insertion of the needle. To investigate potential top-down modulation, half the participants were explicitly requested to empathize with the person in the video, while the other half were told to simply watch and attend to the video. Results from two experiments corroborate previous results showing response facilitation after pain observation. Critically, experiment 2 provides robust evidence that explicit instructions to empathize with a person in pain strengthen response facilitation. We discuss these results considering social cognitive neuroscience and experimental psychology studies of empathy and pain observation.

The Relationship

This article offers an analysis of the child’s right to be heard under Article 12 of the Convention on the Rights of the Child and its application in Norway, through a case study of bullying. The methodology combines a “top-down” legal interpretation of Article 12 in addition to an analysis of Section 9a of the <em>Education Act</em>, juxtaposed with bottom-up approaches. First, a legal analysis of Article 12 and the General Comments of the Convention on the Rights of the Child Committee is provided, with a view to demonstrating the strength of the connection between agency and voice. Looking from the bottom up, therefore, the article then pursues the voices of the bullied children themselves. It places its ear to the ground, so to speak, through an examination of complaints submitted by children to the Ombudsman for Children, in order to “hear” the voices of children subjected to bullying at school, before they are formulated in legal terms before judicial bodies. Finally, I offer a close reading of the report on Section 9a commissioned by the Norwegian Government, published in a 2015 Report (the “Djupedal Report”) in tandem with the leading Supreme Court 2012 decision on bullying, so as to critically examine the fulfilment of Article 12 in Norway. In the final analysis, I argue that in Norwegian bullying cases, though the child has the legal right to be heard, there is no voice, due to the limitations of legal agency for children pursuant to Article 12 of the Convention on the Rights of the Child.
