Review: Do the Different Sensory Areas within the Cat Anterior Ectosylvian Sulcal Cortex Collectively Represent a Network Multisensory Hub?
Current theory supports that the numerous functional areas of the cerebral cortex are organized and function as a network. Using connectional databases and computational approaches, the cerebral network has been demonstrated to exhibit a hierarchical structure composed of areas, clusters and, ultimately, hubs. Hubs are highly connected, higher-order regions that also facilitate communication between different sensory modalities. One region computationally identified network hub is the visual area of the Anterior Ectosylvian Sulcal cortex (AESc) of the cat. The Anterior Ectosylvian Visual area (AEV) is but one component of the AESc that also includes the auditory (Field of the Anterior Ectosylvian Sulcus - FAES) and somatosensory (Fourth somatosensory representation - SIV). To better understand the nature of cortical network hubs, the present report reviews the biological features of the AESc. Within the AESc, each area has extensive external cortical connections as well as among one another. Each of these core representations is separated by a transition zone characterized by bimodal neurons that share sensory properties of both adjoining core areas. Finally, core and transition zones are underlain by a continuous sheet of layer 5 neurons that project to common output structures. Altogether, these shared properties suggest that the collective AESc region represents a multiple sensory/multisensory cortical network hub. Ultimately, such an interconnected, composite structure adds complexity and biological detail to the understanding of cortical network hubs and their function in cortical processing
Commitment to displaying positive emotions at work: an examination of individual and situational antecedents
Studies show that employee emotional displays impact customer behaviors and attitudes (Grandey, Fisk, Mattila, & Sideman, 2002; Pugh, 2001; Tsai, 2001). However, the factors influencing employees\u27 emotional displays have not received much attention. More specifically, research suggests a need to more fully understand the motivational processes underlying employees\u27 emotional displays, particularly in customer service where positive emotional displays are related to customer behaviors and sales performance (Brown & Sulzer-Azaroff, 1994; Diefendorff & Gosserand, in press; Grandey, Fisk, Matilla, & Sideman, 2002; Pugh, 2001; Tsai, 2001). To this end, this investigation examined an expectancy theory model of commitment to positive emotional displays in customer service jobs. Results supported the idea that there is a motivational component behind individual\u27s propensity to follow display rules to express positive emotions. A number of individual and situational variables were found to influence expectancy and valence judgments for positive emotional displays. In turn, expectancy and valence, as well as their multiplicative function, motivational force, were related to commitment to displaying positive emotions. However, expectancy influences commitment to positive displays to a greater extent than valence, when employees consider difficult customer service situations. Results also reveal support for the use of motivational force operationalizations of expectancy theory in order to better understand motivational processes
Subalpine Cover Ecology of Eutamias amoenus, Eutamias townsendii and other small Mammals in Huckleberry Park, Mount Rainier National Park
Little work has been done on the ecology of alpine and subalpine small mammals. They are included in faunal surveys, but little is known of their habits. In the summer of 1969 this study was undertaken in subalpine Huckleberry Park, Mount Rainier National Park, to determine the species of small mammals in the area and some of their relationships with the environment and each other. The relationships between E. amoenus and E. townsendii were of special interest
Cystitis in a Bovine
A Hereford cow, age 5 1/2 years, was admitted to Stange Memorial Clinic on Oct. 20, 1951, for sterility examination with a history of having been bred several times. The cow had been purchased and at the time of purchase was with calf. She gave 108 birth to a normal healthy calf, but would not conceive subsequently
Imputed Abandonment: A Fresh Perspective on Adverse Possession and a Defense of the Objective Standard
Not
Employment and Food During Coronavirus
Key Findings
1. 45% of respondents with jobs experienced some type of job disruption or loss. 19.7% had a reduction in hours or income, 9.3% had been furloughed, and 15.5% had lost their job since the coronavirus outbreak.
2. 38.5% of respondents experiencing job loss or disruption since the outbreak were classified as food insecure.
3. Respondents experiencing job disruption or loss were significantly more likely to be already implementing food purchasing or eating changes and concerned about food access compared to those who did not experience a change in employment.
4. Respondents with job disruption or loss were significantly more likely to need higher amounts of money per week to help meet their basic needs if they could no longer afford food (107 furloughed, 82 with no job impact)
Food Access and Security During Coronavirus: A Vermont Study
Key Findings
1. Respondents reported a 33% increase in food insecurity since the coronavirus outbreak began in Vermont (from 18% to 24%).
2. 45% of respondents with jobs experienced a job disruption or loss.
3. Respondents said the most helpful actions for meeting their food needs would be increased trust in the safety of going to stores and more food in stores.
4. Respondents worried most about food becoming unaffordable and running out of food if they were unable to go out.
5. Vermonters are using a variety of strategies to adapt: a majority of respondents are at least somewhat likely to buy foods that don\u27t go bad quickly (90%); buy different, cheaper foods (69%); and stretch the food they have by eating less (52%)
The Impact of Coronavirus on Vermonters Experiencing Food Insecurity
Key Findings
1. Respondents experiencing food insecurity were more likely to be people of color, female, live in households with children, and live in larger households.
2. 84.2% of respondents who experienced food insecurity at some point in the year before the coronavirus pandemic remained food insecure during the early days of the outbreak.
3. The majority of respondents experiencing food insecurity are not utilizing food assistance programs.
4. â…” of respondents experiencing food insecurity are already buying different, cheaper foods or eating less to make their food last.
5. â…” of respondents experiencing food insecurity with a job had job disruption or loss since the coronavirus outbreak.
6. Vermonters are helping each other – there was a reported doubling in the percentage of people receiving their food via delivery from other people
Surface electromyographic control of a novel phonemic interface for speech synthesis
Many individuals with minimal movement capabilities use AAC to communicate. These individuals require both an interface with which to construct a message (e.g., a grid of letters) and an input modality with which to select targets. This study evaluated the interaction of two such systems: (a) an input modality using surface electromyography (sEMG) of spared facial musculature, and (b) an onscreen interface from which users select phonemic targets. These systems were evaluated in two experiments: (a) participants without motor impairments used the systems during a series of eight training sessions, and (b) one individual who uses AAC used the systems for two sessions. Both the phonemic interface and the electromyographic cursor show promise for future AAC applications.F31 DC014872 - NIDCD NIH HHS; R01 DC002852 - NIDCD NIH HHS; R01 DC007683 - NIDCD NIH HHS; T90 DA032484 - NIDA NIH HHShttps://www.ncbi.nlm.nih.gov/pubmed/?term=Surface+electromyographic+control+of+a+novel+phonemic+interface+for+speech+synthesishttps://www.ncbi.nlm.nih.gov/pubmed/?term=Surface+electromyographic+control+of+a+novel+phonemic+interface+for+speech+synthesisPublished versio
