This paper presents an EERI reconnaissance report for building damage in the 1906 earthquake in San Francisco before the fire began. It is therefore synthetic and “virtual.” Using the evidence that has survived in the form of engineering reports and photographs, the paper presents a modern interpretation of the past in the format of a contemporary report. The paper is a synthesis of past observations and judgments leavened with the hindsight of a hundred years. For the first time in decades earthquake damage is surveyed and discussed through the lens of a professional report rather than being seen as a spectacular disaster. The report presented here is a condensed version of a chapter in a larger textural and photographic study entitled Bracing for Disaster; Earthquake-Resistant Architecture and Engineering in San Francisco, 1838-1933 (Berkeley: The Bancroft Library and Heyday Books, March 2006).

This review paper relates original Mohorovičić, A. lecture DJELOVANJE POTRESA NA ZGRADE (1909, 1911) and its English translation EARTHQUAKE EFFECTS ON BUILDINGS (2009) with M5.5 Zagreb 2020 earthquake damage. Mohorovičić said in Introduction of his lecture in 1909: “another strong earthquake is needed to remind people that the building techniques should be further developed and improved…”. Oliver Wendell Holmes (1809-1894) said once: “The young man knows the rules, but the old man knows the exceptions”. This should remined us that going Back to the Future after strong earthquake, we must go Back to the Past, and look after Mohorovičić’s 15 rules how to build earthquake-resistant buildings. He tells us how to build, and unfortunately, we were left unprepared again and didn’t listen wisdom words of an “old man”.

AbstractTransgender women face a serious risk of HIV infection. Despite this, there is limited knowledge and use of Pre-exposure prophylaxis (PrEP). We measured the continuity of prevention across services in the PrEP cascade and correlates of PrEP use among trans women in San Francisco enrolled in the 2019/20 National HIV Behavioral Surveillance Study. Knowledge and use of PrEP among trans women in San Francisco increased in recent years; almost all (94.0%) had heard about PrEP, 64.7% had discussed PrEP with a healthcare provider, and 44.8% had taken PrEP in the past 12 months. PrEP use was associated with participation in a PrEP demonstration project (aOR = 31.44, p = 0.001) and condomless receptive anal intercourse (aOR = 3.63, p = 0.024). Injection drug use was negatively associated (aOR = 0.19, p = 0.014). Efforts are needed to combat the gender-based stigma and discrimination faced by trans women, which can result in avoidance and mistrust of the medical system.

This work presents updated reconstructions of watershed runoff to San Francisco Estuary from tree-ring data to AD 903, coupled with models relating runoff to freshwater flow to the estuary and salinity intrusion. We characterize pre-development freshwater flow and salinity conditions in the estuary over the past millennium and compare this characterization with contemporary conditions to better understand the magnitude and seasonality of changes over this time. This work shows that the instrumented flow record spans the range of runoff patterns over the past millennium (averaged over 5, 10, 20 and 100 years), and thus serves as a reasonable basis for planning-level evaluations of historical hydrologic conditions in the estuary. Over annual timescales we show that, although median freshwater flow to the estuary has not changed significantly, it has been more variable over the past century compared to pre-development flow conditions. We further show that the contemporary period is generally associated with greater spring salinity intrusion and lesser summer–fall salinity intrusion relative to the pre-development period. Thus, salinity intrusion in summer and fall months was a common occurrence under pre-development conditions and has been moderated in the contemporary period due to the operations of upstream reservoirs, which were designed to hold winter and spring runoff for release in summer and fall. This work also confirms a dramatic decadal-scale hydrologic shift in the watershed from very wet to very dry conditions during the late 19th and early 20th centuries; while not unprecedented, these shifts have been seen only a few times in the past millennium. This shift resulted in an increase in salinity intrusion in the first three decades of the 20th century, as documented through early records. Population growth and extensive watershed modification during this period exacerbated this underlying hydrologic shift. Putting this shift in the context of other anthropogenic drivers is important in understanding the historical response of the estuary and in setting salinity targets for estuarine restoration. By characterizing the long-term behavior of San Francisco Estuary, this work supports decision-making in the State of California related to flow and salinity management for restoration of the estuarine ecosystem.

ADHD is a well-known, chronic disorder that persists in adulthood. During the past 20 years its existence in adults is becoming clearer, yet its dynamic aspects are rarely discussed. The treatment of adults is vital, as much as that of children; however the literature discussing it, especially its non-pharmacological aspect, is scarce.We describe the results of our treatment with drama-therapy of two groups of adults with ADHD. These groups included 11 adults (from both groups), men and women, from most socioeconomic strata, aged ≥ 60 yrs., who were diagnosed as suffering from ADHD and were treated for it for the first time in their life. Drama-therapy was selected as we believed it to be a useful method with associative, distracted ADHD patients, since it enabled the use of transitional space through non-verbal images and acts.This presentation discusses the basic themes with which patients began therapy. Interestingly, all patients, however different, shared the same themes that were built on self doubt and the pre-presumption of disappointment. The impairment related to ADHD, that was felt, but not understood, led to a strong experience of heavy losses, which we tried to define separately: of a clear path, of control, of the inner perception of borders and of the loss of an integrative inner self. All these losses were accumulated in the transitional space in a place we named “Nowhere land”.We would like to present these themes of losses and of becoming lost and to discuss their meaning.

AbstractMons. Antonio Batista Fragoso has been bishop of Crateus in Northeast Brazil for the past ten years. Eighty percent of the 360,000 people in his diocese are impoverished peasants who engage in rudimentary farming. At least half of the peasants are landless. It is among these people that Bishop Fragoso has encouraged the formation of small grassroots Christian communities that are responsible for a profound change in the patterns of Christian living in his diocese. The following is LP's translation of excerpts from a talk that Bishop Fragoso gave to his fellow bishops and priests in Managua in October, 1980. This is the first time it has appeared in English.

AbstractThe past decade has evinced a boom of computer-based approaches to aid movement assessment in early infancy. Increasing interests have been dedicated to develop AI driven approaches to complement the classic Prechtl general movements assessment (GMA). This study proposes a novel machine learning algorithm to detect an age-specific movement pattern, the fidgety movements (FMs), in a prospectively collected sample of typically developing infants. Participants were recorded using a passive, single camera RGB video stream. The dataset of 2800 five-second snippets was annotated by two well-trained and experienced GMA assessors, with excellent inter- and intra-rater reliabilities. Using OpenPose, the infant full pose was recovered from the video stream in the form of a 25-points skeleton. This skeleton was used as input vector for a shallow multilayer neural network (SMNN). An ablation study was performed to justify the network’s architecture and hyperparameters. We show for the first time that the SMNN is sufficient to discriminate fidgety from non-fidgety movements in a sample of age-specific typical movements with a classification accuracy of 88%. The computer-based solutions will complement original GMA to consistently perform accurate and efficient screening and diagnosis that may become universally accessible in daily clinical practice in the future.

Two new species and one new record species of the genus Pseudonereis are described from specimens collected from ecological surveys of coasts of Taiwan and an offshore island during the past 15 years: P. jihueiensis n. sp., P. kihawensis n. sp., and P. trimaculata. Epitokes of P. jihueiensis n. sp. and P. trimaculata are also described. Pseudonereis jihueiensis n. sp. can be distinguished from congeners by having edentate jaws, χ-shaped ridge pattern of Areas VI–V–VI, parapodial morphology (i.e., length ratio of dorsal cirrus to dorsal ligule or presence of small pennant-like dorsal ligule, shape of dorsal ligule in certain region of chaetigers), and no heterogomph spinigers in the subacicular fascicle of the neuropodia. Pseudonereis kihawensis n. sp. differs from congeners by having crescent-shaped pointed-bars in Area VI, λ-shaped ridge pattern of Areas VI–V–VI, parapodial morphology (i.e., length ratio of dorsal cirrus to dorsal ligule or presence of small pennant-like dorsal ligule or shape of dorsal ligule in certain region of chaetigers), and no heterogomph spinigers in the subacicular fascicle of the neuropodia. Pseudonereis trimaculata, a species originally described from Indonesia, is reported from Taiwan for the first time. A table of key characters for all species of Pseudonereis is provided.

The origins of the imperial cult in Smyrna date back to the Hellenistic period. It is a fact that political concerns were effective in the generation of such cults. Predicting the super power of the future and proving to be a loyal ally whilst acting in satisfactory behaviors were essential factors. The right preference made between two fighting or contending powers ensured that a city would benefit from various privileges in the future. For example, Symrna, which had established a cult in the city previously on behalf of Stratonice, the mother of Antiochus II of Seleucid dynasty, would do the same by building a temple in the name of the dty of Rome for the first time in Asia in 195 BC, after recognizing the rising power. Later on, while giving permission to the provinces that wanted to establish an imperial cult, the Roman emperors and the Senate would consider first, their relationships with Rome in the past and second, their origins. Smyrna, building its relationships with the Roman state on a solid basis, was granted the title of neokoros three times by the Roman Emperors Tiberius, Hadrianus and Caracalla, respectively. In this essay, the development of the Roman imperial cult in Smyrna is discussed within the historical process outlined above. An attempt has been made to put forth new opinions about the issue by discussing the academicians' evaluations on the imperial cult, which apparently was effectively executed in Smyrna between the first and third centuries AD, with the support of epigraphic and numismatic evidences.

This co-authored article examines the oldest known treaty between incoming Europeans and Indigenous North Americans to derive five basic principles to guide healthy, productive relationships between Indigenous community-based researchers and university-based ones. Rick Hill, Tuscarora artist and knowledge keeper from the Six Nations of the Grand River, publishes for the first time here the most complete oral history that exists today of that ancient treaty, from the early seventeenth century, known as the Two Row Wampum or the Covenant Chain agreement. Interspersed with Dr. Hill’s reflections, Daniel Coleman, a settler professor of English and Cultural Studies at McMaster University, outlines five principles for research partnerships derived from the discussions of the Two Row Research Partnership seminars that Hill and Coleman have been hosting at Deyohahá:ge: Indigenous Knowledge Centre for the past four years. Formed between the Hodinöhsö:ni’ confederacy and Dutch merchants arriving near Albany, New York in 1609, the Two Row Wampum-Covenant Chain treaty set the precedent for nation-to-nation treaties between European colonial powers and Indigenous peoples with two parallel rows representing the Hodinöhsö:ni’ canoe and the Dutch ship sailing down the shared river. Each party agreed to keep their beliefs and laws in their separate vessels, and on this basis of interdependent autonomy, they established a long-lasting friendship. This article suggests that by renewing our understanding of the Two Row Wampum-Covenant Chain treaty, Indigenous and non-Indigenous researchers alike can rebuild relationships of trust and cooperation that can decolonize Western presumptions and re-establish healthy and productive research partnerships.
