Settlement patterns recovered by archaeologists differ fundamentally from synchronic settlement patterns analyzed by geographers since they are a static record of occupations that may often have had differing periods of use in the past. Many maps of the “settlement pattern” of prehistoric phases show more occupations than were ever simultaneously occupied. After discussing some of the problems this can cause, I describe a way of characterizing past settlement dynamics and a method for estimating (1) the mean number of likely simultaneous occupations for a region and (2) phase-to-phase differences in mean occupation span. The method is illustrated by the analysis of settlement data from the Ixtapalapa region in the Basin of Mexico.

Mapping of Klungkung sub-district settlement pattern: analysis of settlement pattern and characteristic. The research on Klungkung subdistrict settlement pattern aims to see whether the pattern is following “traditional” residential pattern theory or else. The pattern of community settlements can be used as an indicator of social dynamics as well as social problems. Similarly, it can be an indication of development potential or just the opposite for a development, whether from economic, social, cultural, even political. This study is limited only to find early indications of settlement patterns and residential characteristics. The method used is descriptive qualitative by utilizing GIS software to map residential locations obtained from key respondents and public respondents. The results show that the distribution of growing settlements patterns from core towards outside is the characteristics of the population based on religion or belief. While the pattern of settlements based on the character of the profession/work shows an orbital form, like the planets that surround the sun. Ethnic or race character does not show any particular pattern. This research is a preliminary study on the pattern of settlements in the era of globalization and development of Semarapura city in Klungkung regency. There is a tendency that the settlement pattern is not centered oriented anymore.

Data from Coba, Quintana Roo, Mexico indicate strongly that Arnold and Ford"s (1980) settlement pattern analysis of Tikal, Guatemala is the result of an insufficient sample combined with their inability to distinguish between vaulted and unvaulted masonry structures. These deficiencies, together with a standard labor investment calculation for shrines and the use of an invalid measuring technique, have produced a distorted homogenized view of Classic Maya urban organization.

AbstractIn this paper I focus on the regional surveys undertaken in 1960–1975—their development, implementation, key accomplishments, and major shortcomings. I also point to how resulting survey data and surface collections have provided the foundations for subsequent research on a variety of specific problems, sites, and locales, and how complementary historical and ethnographical studies have contributed to interpretations of pre-Columbian settlement patterns. I consider how off-site survey can, and should, complement the more extensive regional surveys that have been carried out in the past. While lamenting the archaeological record lost to modern development, in a more positive vein I suggest lines of productive future investigation that might still be undertaken to extend the significance of past results, evaluate a series of questions and hypotheses defined by the surveys, and help conserve archaeological sites and collections for future study.

Scrub typhus (Orientia tsutsugamushi), is a strict intracellular bacterium which is reported to be a recent threat to parts of southern India. There is re-emergence of scrub typhus during the past few years in Chennai. Scrub typhus is an acute febrile illness which generally causes non-specific symptoms and signs. The clinical manifestations of this disease range from sub-clinical disease to organ failure to fatal disease. This study documents our laboratory experience in diagnosis of scrub typhus in patients with fever and suspected clinical symptoms of scrub typhus infection for a period of two years from April 2014 to April 2016 using immunochromatography and IgM ELISA methods. The study was conducted on 648 patients out of whom 188 patients were found to be positive for scrub typhus. Results also showed that pediatric (0 -12 years) and young adults (20 – 39 years) were more exposed to scrub typhus infection and female patients were more infected compared to male. The study also showed that the rate of infection was higher between September to February which also suggested that the infection rate is proportional to the climatic condition. Statistical analysis showed that the mean age of the patients in this study was 37.6, standard deviation was 18.97, CV % was 50.45.

Abstract Background There is a paucity of data assessing outcomes of alternate fidaxomicin strategies in patients with recurrent Clostridioides difficile infection (rCDI). The objective of our study is to evaluate a tapered-pulsed (T-P) fidaxomicin regimen that was administered immediately following a course of CDI treatment with initial symptom resolution in patients with multiple rCDI. Methods We reviewed the characteristics and outcomes of 46 consecutive patients who received T-P fidaxomicin between January 1, 2014-June 30, 2019 in a specialty CDI clinic. The first episode in which fidaxomicin T-P was administered was analyzed. Failure was defined as the persistence of diarrhea and/or the need for additional CDI treatment at any time on T-P fidaxomicin. Sustained clinical cure (SCC) was defined as resolution of diarrhea without recurrence. Recurrence was defined as the return of diarrhea requiring retreatment with CDI therapy after completion of T-P fidaxomicin. Both SCC and recurrence were evaluated at 30 and 90 days after completion of T-P fidaxomicin. Results The mean±SD age of the 46 patients was 63.2±19.9 years, 71.7% were female, and the mean±SD CDI episodes within the past year was 3±1.4 . Most patients (73.9%) had previously failed a vancomycin tapered and/or pulsed regimen. Prior to administering T-P fidaxomicin, a treatment regimen was given to ensure resolution of symptoms. The CDI treatment most commonly used (58.7%) was vancomycin. The T-P fidaxomicin regimen used consisted of 200 mg given once daily for 7 days followed by 200 mg every other day for a median (min-max) duration of 33 (6-120) days. Two patients (4%) failed to respond to T-P fidaxomicin; 34 (74%) and 28 (61%) achieved SCC at 30 and 90 days, respectively. Among the 44 patients that successfully completed the T-P fidaxomicin regimen, recurrence developed in 10 (22.7%) and 16 (36.4%) of patients at 30 and 90 days, respectively, with a median (min-max) time to recurrence of 20 (3-87) days (Figure 1). Four patients with recurrence had received subsequent systemic antibiotics. Figure 1. Course of CDI therapy and follow-up Conclusion A tapered-pulsed fidaxomicin strategy may be effective in patients with multiply rCDI who are refractory to other treatments, including a vancomycin tapered and pulsed regimen.

OBJECTIVE Scientific productivity, as assessed by publication volume, is a common metric by which the academic neurosurgical field assesses its members. The number of authors per peer-reviewed article has been observed to increase over time across a broad range of medical specialties. This study provides an update to this trend in the neurosurgical literature. METHODS All publications from January 1, 1980, to April 30, 2020, were queried from four neurosurgical journals: Neurosurgery, Journal of Neurosurgery (JNS), JNS: Pediatrics, and JNS: Spine. Publication information was acquired from the National Center for Biotechnology Information Entrez database and reconciled with the Scopus database. Publication type was limited to articles and excluded editorials, letters, and reviews. The number of authors and affiliation counts were determined based on structured abstract fields provided in the two databases. RESULTS Between January 1, 1980, and April 30, 2020, the overall increase in author count for the four neurosurgical journals was 0.12 to 0.18 authors per year (p < 0.001). For Neurosurgery, the mean (SD) author count increased from 2.81 (1.4) in 1980–1985 to 7.97 (4.92) in 2016–2020 (p < 0.001). For the JNS, the mean (SD) author count increased from 2.82 (1.04) in 1980–1985 to 7.6 (3.65) in 2016–2020 (p < 0.001). The percentage of articles with more than 10 authors increased from 0.2% to 22.3% in Neurosurgery and from 1.9% to 17.5% in JNS. Only 28% of the author count variation was explained by an increasing number of institutional or departmental affiliations. CONCLUSIONS Author counts for peer-reviewed articles in neurosurgical academic journals have increased significantly during the past 4 decades, with large increases in the numbers of articles with more than 10 authors in the past 5 years. A total of 28% of the variation in this increase can be explained by an increase in multiinstitutional or multidepartmental studies.

- The article explores megastructures in relation to their impact on local transport networks and nodes. The area examined is Portugal, where the recent construction of giant shopping malls, industrial estates and logistics centres has in turn led to large-scale infrastructures that have been superimposed on a settlement pattern consisting, in many cases, of urban agglomerations serviced by rural roads. The resulting landscape reveals a juxtaposition of completely different elements in terms of both scale and impact, often the outcome of urban zoning projects intruding on fragmented urbanisation. The resulting image is one of scattered settlement patterns. Behind these phenomena one can see the effects of splintering urbanism. The difficulty in coordinating, in time and space, the decisions made and actions taken by a wide variety of individuals and institutions is becoming increasingly more complex.

The Difference

The error in estimating the orientation of a dot pattern was measured as the difference between the orientation of the least-squared-distances line (LS-line) of the pattern and the orientation of a line adjusted by the subject to match the perceived orientation of the pattern. Analysis of the mean errors (averaged over ten subjects) obtained for one hundred patterns confirmed that the orientation of the LS-line represents the orientation of elongated dot-patterns. It is shown that estimated orientation was systematically biased towards the nearest 45° oblique meridian. This bias points to the importance of the ±45° directions as natural norms for left- and right-side tilt in the frontoparallel plane.

If the concept of “free will” is reduced to that of “choice” all physical world share the latter quality. Anyway the “free will” can be distinguished from the “choice”: The “free will” involves implicitly a certain goal, and the choice is only the mean, by which the aim can be achieved or not by the one who determines the target. Thus, for example, an electron has always a choice but not free will unlike a human possessing both. Consequently, and paradoxically, the determinism of classical physics is more subjective and more anthropomorphic than the indeterminism of quantum mechanics for the former presupposes certain deterministic goal implicitly following the model of human freewill behavior. Quantum mechanics introduces the choice in the fundament of physical world involving a generalized case of choice, which can be called “subjectless”: There is certain choice, which originates from the transition of the future into the past. Thus that kind of choice is shared of all existing and does not need any subject: It can be considered as a low of nature. There are a few theorems in quantum mechanics directly relevant to the topic: two of them are called “free will theorems” by their authors (Conway and Kochen 2006; 2009). Any quantum system either a human or an electron or whatever else has always a choice: Its behavior is not predetermined by its past. This is a physical law. It implies that a form of information, the quantum information underlies all existing for the unit of the quantity of information is an elementary choice: either a bit or a quantum bit (qubit).

The Past

During the past decade there has been a considerable increase in literature documenting the growth of Indian Ocean port cities. Famously described as the Brides of the Sea, port cities such as Cape Town, Karachi, Bombay (Mumbai), Madras (Chennai), Calcutta, Rangoon, Singapore, and Jakarta were the bridgeheads for the establishment of European dominance. They fostered greater connectivity and intercultural exchanges, and they produced distinctive urban settlement patterns, environments, and social relationships.
