Mapping the Good Neighbor

American tourism in Mexico increased significantly during the Good Neighbor era. By creating tourist maps, cartographers on both sides of the border participated in an intentional, ideological process of reshaping these tourists’ views of Mexico. They sought to transform Americans’ perceptions not only of Mexicans and their history but also of the physical environment. Their Mexico was a place of contrast, suspended in the romantic past and engaged in modernity. Although cartographers constructed a new Mexico through their maps, they did not challenge perceptions of an asymmetrical power dynamic that had defined U.S.-Mexico relations and the tourism industry at large. Instead, their maps reinforced, reproduced, and contributed to it. Cartographers, like the maps they created, were not passive or inconsequential actors. Analyzing the ideas, relationships, and myths embedded in their maps expands our understanding of transnational tourism, environmental change, selective history, and imagined communities in the twentieth century.

To See and to Tell: Lessing’s Criticism of Ageism in The Diary of a Good Neighbor

The Diary of a Good Neighbor is one of a series of works concerning age problems in the contemporary western society written by the Nobel laureate Doris Lessing. Through the record of the last days of Maudie Fowler, a ninety-two-year-old lower-class woman by a middle-aged professional Jane Somers, Lessing questions the modern social care system and criticizes the hidden social prejudice against the elderly. Lessing observes the defect of the modern social care institutions in oppressing individual choice and excluding aged people, and points out the professional service they provide cannot really comfort the aged individuals, which constructs a dilemma for both the institutions and the aged group. Different from the ageist neglect of the aged group, Lessing gives a detailed exhibition of both Maudie’s daily life and her inner world, which builds a personal connection between the old and the young and draws this isolated group close to the public. Lessing also explores the taboo topic of old age, sickness and death and gives a full display of Maudie’s tenacious wrestling with death, which shows the sublime of human life and challenges the ageist view of the co-decaying of spirit and body.

21st Century Good Neighbor Program: An Easily Generalizable Program to Reduce Social Isolation in Older Adults

Aim: In this once-in-a-lifetime humanitarian crisis, what does it mean to be a good neighbor? It means that as a community, we must address loneliness and barriers to care faced by vulnerable populations such as older adults. We share an inexpensive longitudinal experiential service-learning program implemented by health professions and undergraduate student volunteers that aims to help alleviate loneliness in older adults while imparting meaningful experiences to volunteers.Intervention Design and Setting: The 21st Century Good Neighbor Program is an observational cohort study of an experiential service-learning program started in May 2020, and this article shares the results collected after 1 year. This longitudinal, weekly phone call program was conducted in a single community setting in the Midwestern part of the United States. Older adults over the age of 60 served by a local community service agency (CSA) were invited to participate. Volunteers consisted of students 18 or older. Student volunteers made regular phone calls to a pair of older adults throughout the course of 1 year following standardized call scripts. The loneliness of the older adults was measured by volunteers using the 3-item UCLA Loneliness Assessment.Results: 261 older adults were engaged in conversations with a volunteer. A total of 1,391 calls were accepted by older adults and the median length of a welcomed call was 11 min. The average baseline loneliness score was 4.156 ± 1.41 and the prevalence of social isolation was 19.5%. There was no significant change in the UCLA loneliness score in the first year of follow up. However, a majority of volunteers (88%) agreed or strongly agreed that the program had a positive impact on them. In addition, the program identified 257 issues older adults faced that required follow-up. The most prevalent concerns referred to the community service agency by volunteers were issues related to utilities, food and transportation access.Conclusion: The 21st Century Good Neighbor Program is a unique intervention in which student volunteers and older adults paired by a community service agency forge relationships though a longitudinal phone call-based program. This easy-to-implement program provides another layer of support to identify and refer issues that impact social determinants of health. The added benefit of volunteer satisfaction in the setting of COVID 19 pandemic is heartening. We hope to continue to study the impact of this intervention on social isolation in this vulnerable population.

The l-good-neighbor edge connectivity of graphs

The l -good-neighbor edge connectivity is an useful parameter to measure the reliability and tolerance of interconnection networks. For a graph H with order p and an integer l (l ≥ 0), an edge subset X ⸦ E(H) is called a l-good-neighbor edge-cut if H − X is disconnected and the minimum degree of every component of H − X is at least £. The order of the minimum l-good-neighbor edge-cut of H is called the l-good-neighbor edge connectivity of H, denoted by λ l (H). In this paper, we show λ(H) ≤ λ l+1(H), obtain the bounds of λl (H) when 0 ≤ l ≤ [p-2/2], character some graphs with the small λl (H) and get some results about the Erdös-Gallai-type problem about λl (H).

The 3-Good Neighbor Edge-Fault-Tolerant Strong Menger Edge Connectivity on the Class of BC Networks

A graph [Formula: see text] is called strongly Menger edge connected (SM-[Formula: see text] for short) if the number of disjoint paths between any two of its vertices equals the minimum degree of these two vertices. In this paper, we focus on the maximally edge-fault-tolerant of the class of BC-networks (contain hypercubes, twisted cubes, Möbius cubes, crossed cubes, etc.) concerning the SM-[Formula: see text] property. Under the restricted condition that each vertex is incident with at least three fault-free edges, we show that even if there are [Formula: see text] faulty edges, all BC-networks still have SM-[Formula: see text] property and the bound [Formula: see text] is sharp.

Reliability Evaluation of Bicube-Based Multiprocessor System under the g-Good-Neighbor Restriction

Multiprocessor systems are commonly deployed for big data analysis because of evolution in technologies such as cloud computing, IoT, social network and so on. Reliability evaluation is of significant importance for maintenance and improvement of fault tolerance for multiprocessor systems, and system-level diagnosis is a primary strategy to identify the faulty processors in the systems. In this paper, we first determine the [Formula: see text]-good-neighbor connectivity of the [Formula: see text]-dimensional Bicube-based multiprocessor system [Formula: see text], a novel variant of hypercube. Besides, we establish the [Formula: see text]-good-neighbor diagnosability of the Bicube-based multiprocessor system [Formula: see text] under the PMC and MM* models.
