Wilson’s (1998) notion of consilience among disciplines should be a goal for cartographers. Consilience requires important facts and fact-based theories to apply across disciplines. This paper reviews research on visual attention as an example of a topic shared by information science disciplines. Attention is considered as a competition between neural processes that allow information to be selected and emphasized for perceptual processing. Visual attention has been modeled as a spotlight, zoom lens, gradient, and multiple spotlights. It is argued that visual attention can impact multiple map reading processes and that cartographers can use knowledge about the effects of attention on map reading to design more effective maps. Attention can be directed to locations, objects, and features in the visual field and impacts performance on a variety of map reading tasks. Important general questions relating visual attention and map reading are stated and the literature providing answers discussed. The “dark side” of attention is also discussed and linked to the concepts of inhibition of return, visual marking, inattentional blindness, change blindness, and the attentional blink. Specific map-reading processes affected by visual attention are considered that include figure-ground segregation, visual search, and object selection and grouping. Research trends related to cartographic design and map reading are considered for these processes. Future cartographic studies are considered in four categories—vision before attention, vision with attention, vision after attention, and vision without attention. Understanding the role of visual attention in map reading should be a goal of cartographers interested in producing effective maps.

Abstract Action and Perception are closely linked in many behaviors necessitating a close coordination between sensory and motor neural processes so as to achieve a well-integrated smoothly evolving task performance. To investigate the detailed nature of these sensorimotor interactions, and their role in learning and executing the skilled motor task of speaking, we analyzed ECoG recordings of responses in the high-γ band (70 Hz-150 Hz) in human subjects while they listened to, spoke, or silently articulated speech. We found elaborate spectrotemporally-modulated neural activity projecting in both forward (motor-to-sensory) and inverse directions between the higher-auditory and motor cortical regions engaged during speaking. Furthermore, mathematical simulations demonstrate a key role for the forward projection in learning to control the vocal tract, beyond its commonly-postulated predictive role during execution. These results therefore offer a broader view of the functional role of the ubiquitous forward projection as an important ingredient in learning, rather than just control, of skilled sensorimotor tasks.

Purpose – The purpose of this paper is to elucidate the role that visual measures of attention to product and information and price display signage have on purchase intention. The authors assessed the effect of visual attention to the product, information or price sign on purchase intention, as measured by likelihood to buy. Design/methodology/approach – The authors used eye-tracking technology to collect data from Australian and US garden centre customers, who viewed eight plant displays in which the signs had been altered to show either price or supplemental information (16 images total). The authors compared the role of visual attention to price and information sign, and the role of visual attention to the product when either sign was present on likelihood to buy. Findings – Overall, providing product information on a sign without price elicited higher likelihood to buy than providing a sign with price. The authors found a positive relationship between visual attention to price on the display sign and likelihood to buy, but an inverse relationship between visual attention to information and likelihood to buy. Research limitations/implications – An understanding of the attention-capturing power of merchandise display elements, especially signs, has practical significance. The findings will assist retailers in creating more effective and efficient display signage content, for example, featuring the product information more prominently than the price. The study was conducted on a minimally packaged product, live plants, which may reduce the ability to generalize findings to other product types. Practical implications – The findings will assist retailers in creating more effective and efficient display signage content. The study used only one product category (plants) which may reduce the ability to generalize findings to other product types. Originality/value – The study is one of the first to use eye-tracking in a macro-level, holistic investigation of the attention-capturing value of display signage information and its relationship to likelihood to buy. Researchers, for the first time, now have the ability to empirically test the degree to which attention and decision-making are linked.

AbstractThis paper highlights the dark side of power imbalance regarding its consequences in agri-food supplier–buyer relationships. We report on findings from two studies. The first study is based on a sample of 105 key informants, while study 2 is based on a sample of 444 key informants, all from the cocoa agri-food supply market of Ghana. While the first study focuses on the antecedents of power imbalance and its consequences, the second study explores the role of cooperatives/collective action in minimizing supplier exploitation. Data from these studies were analysed using the partial least squares technique (SmartPLS). Analysis of these findings shows switching costs’ impact on power imbalance to be curvilinear, while power imbalance has a curvilinear relationship with opportunism. The negative consequences of power imbalance are further exacerbated by dependency and the lack of joint action. Furthermore, we found the negative impact of power imbalance on financial performance to be stronger for non-cooperative members than for cooperative members, while, counterintuitively, we found the positive impact of economic satisfaction on financial performance to be stronger for non-cooperative members than for cooperative members.

Cellular Iron

Heme oxygenase (HO)-1 is known to metabolize heme into biliverdin/bilirubin, carbon monoxide, and ferrous iron, and it has been suggested to demonstrate cytoprotective effects against various stress-related conditions. HO-1 is commonly regarded as a survival molecule, exerting an important role in cancer progression and its inhibition is considered beneficial in a number of cancers. However, increasing studies have shown a dark side of HO-1, in which HO-1 acts as a critical mediator in ferroptosis induction and plays a causative factor for the progression of several diseases. Ferroptosis is a newly identified iron- and lipid peroxidation-dependent cell death. The critical role of HO-1 in heme metabolism makes it an important candidate to mediate protective or detrimental effects via ferroptosis induction. This review summarizes the current understanding on the regulatory mechanisms of HO-1 in ferroptosis. The amount of cellular iron and reactive oxygen species (ROS) is the determinative momentum for the role of HO-1, in which excessive cellular iron and ROS tend to enforce HO-1 from a protective role to a perpetrator. Despite the dark side that is related to cell death, there is a prospective application of HO-1 to mediate ferroptosis for cancer therapy as a chemotherapeutic strategy against tumors.

Although place-based investigations into human phenomena have been widely conducted in the social sciences over the last decades, this notion has only recently transgressed into Geographic Information Science (GIScience). Such a place-based GIS comprises research from computational place modeling on one end of the spectrum, to purely theoretical discussions on the other end. Central to all research that is concerned with place-based GIS is the notion of placing the individual at the center of the investigation, in order to assess human-environment relationships. This requires the formalization of place, which poses a number of challenges. The first challenge is unambiguously defining place, to subsequently be able to translate it into binary code, which computers and geographic information systems can handle. This formalization poses the next challenge, due to the inherent vagueness and subjectivity of human data. The last challenge is ensuring the transferability of results, requiring large samples of subjective data. In this paper, we re-examine the meaning of place in GIScience from a 2018 perspective, determine what is special about place, and how place is handled both in GIScience and in neighboring disciplines. We, therefore, adopt the view that space is a purely geographic notion, reflecting the dimensions of height, depth, and width in which all things occur and move, while place reflects the subjective human perception of segments of space based on context and experience. Our main research questions are whether place is or should be a significant (sub)topic in GIScience, whether it can be adequately addressed and handled with established GIScience methods, and, if not, which other disciplines must be considered to sufficiently account for place-based analyses. Our aim is to conflate findings from a vast and dynamic field in an attempt to position place-based GIS within the broader framework of GIScience.

Purpose – The purpose of this study is to have a closer look at the awareness of referencing utilities among the library professionals in India. In a research environment, referencing and bibliography play an important role in the dissemination of research findings through scholarly writings. Citing references while writing scholarly articles has become more eloquent mainly due to the availability of a range of bibliography management utilities. Currently, there are various types of Bibliography Management Software (BMS) available for the management of the citation, referencing and compiling bibliographies. Librarians have a crucial role to play in helping the faculty, students and research scholars in the process of writing their scholarly articles and theses, especially in the area of referencing. Design/methodology/approach – The study was conducted through an online survey with an aim to assess the perception, awareness and use of BMS by the Library and Information Science (LIS) professionals in India. Findings – In the academic environment, published results of research findings are crucial for the advancement of knowledge. The published research findings are often supported and disputed using the citation of previous studies. There are a number of supporting technologies that are intended to help in procuring needed citations and streamlining them for better research output. The role of the librarian in this endeavor is undisputed. This study shows that there is a need for strengthening the awareness of BMS at the institutional level and also hands-on experience is needed for library professionals to help in the process of research writing and advocate for adopting correct referencing style (citation style) while writing scholarly articles. Practical implications – The increased use of information and communication technology in the process of scholarly writing, especially in the search and retrieval of relevant articles and the availability of electronic journals and books, have resulted in an increased number of research articles being written by research scholars. The downside to this overflow of scholarly and creative writing is the incorrect way of using referencing style in the dissemination of research and the possibilities of malpractice and plagiarism. This study will help in creating awareness of the utility of citation and BMS in content writing, especially among library and information professionals, as they play an important role in facilitating research. Social implications – This study will be beneficial for the LIS professionals in understanding the effectiveness of their services when complemented by the use of technology-powered tools. Creating awareness of the use of BMS in content development in scholarly communication promises to create a flawless scholarly output as library professionals will help researchers in guiding research writings with correct referencing and citation. Originality/value – Use of BMS helps in the development of content in an organized, methodical and scientific way. The role of library and information professionals working with different researchers and scholars in advocating and practicing the use of BMS will go a long way in creating more streamlined content.
