title: Survey of Consumer Attitudes and Behavior, Fall 1973
title: Version 2

description: This survey was undertaken to assess consumer sentiment and buying plans, as well as to provide information on their savings and investment habits and perceptions of government. Open-ended questions were asked concerning evaluations and expectations about personal finances, employment, recession, price changes, and the national business situation. Additional variables probe respondents' buying intentions for a house, automobiles, appliances, and other consumer durables, and respondents' appraisals of present market conditions for purchasing houses and other durables. Other variables probe respondents' assessments of their financial status relative to the previous year, their views of the government in Washington, the need for governmental changes, military spending, government support for Black people, and their satisfaction with their income and their jobs, as well as their opinion of married women working outside the home, women's liberation, and penalties for marijuana use. Information is also provided on respondents' political party identification, time spent with their children, savings accounts, contributions to charitable organizations, and car ownership and plans to buy a new one. Demographic variables provide information on respondents' age, sex, race, ethnic group, marital status, education, occupation, employment status, and family income.

description: All families living in continental United States dwelling units, exclusive of those on military reservations.
description: One respondent from each family unit in the dwellings sampled, usually the head of the family, or the wife. The dwelling units were selected by area probability sampling from primary sampling units. For each dwelling unit in the sample, an interview was sought with a respondent from the primary family and from each secondary family (if any). The head of the family (usually the husband) was the preferred respondent, but the wife could substitute if the head was not readily available.

description: Seventeen soccer players performed three counter movement jumps on two force plates. Then each participant perfomed three times a single leg squat and a cross over hop test wearing two magnetic-inertial measurement units located on the tibia and foot. The row data are shared with no pre-processing. <br> Force plate data are .c3d files and can be opened using open source softwares like Mokka (https://biomechanical-toolkit.github.io/mokka/). Inertial sensor data are .csv files and can be open with Google Sheet, Notepad, or OpenOffice Calc. <br> Force Plate data: Each folder contains three .c3d files. Each file contains the force plate data of each counter movement jump. The force plate system of reference were as follows: X = antero-posterior, Y = medio-lateral, Z = vertical. <br> IMU data: Each folder contains two folders, DX and SX referring to the two body sides, right and left respectively. In each side-related folder there are all the performed trials: - cht = cross over hop test - sls = single leg squat Sensor 139 was placed on the tibia/shank. Sensor 204 was placed on the foot. Sensor 284 was placed on the tibia/shank. Sensor 293 was placed on the foot. Details on sensor position and reference frames are presented in Fig. 1 of the related paper: "Reliability of wearable sensors-based parameters for the assessment of knee stability"

title: Anxiety is Equal to Symptoms and Primordial

description: Based on a prior study of observation and accumulation of the enrollment lists from the even semester of 2022, this investigation identified anxiety as the primary concern. It used the library method to investigate anxiety from three main perspectives, including the theories of anxiety, learning trauma, and educational change. The researcher discovered that from elementary to higher education levels, there should addressed with students as the center principle through collaboration as one of the associated studies of second resources and analysis of the prior publications with the range of publication approximately 2022. Additionally, suggest more study on the nature of the learning environment, particularly in student centers that value cooperation as one of their core values, in order to comprehend the impact of anxiety and its various manifestations. Therefore, conduct study in the future at all levels of education, from elementary school to university, as is thought to be feasible. It is feasible for people, especially politicians, to permit improvement of inadequacy.

description: This dataset contains the Global Degree of Urbanisation Classification of administrative units delineated by the Global ADMinistrative layer version 3.6 (GADM36) according to the application of stage II of the Degree of Urbanisation. The classification is based on the Global Human Settlement Layer (GHSL) global datasets GHS R2022: the settlement classification GHS-SMOD (GHS-SMOD_GLOBE_R2022A), population grid GHS-POP (GHS-POP_GLOBE_R2022A), and built-up surface GHS-BUILT-S (GHS-BUILT-S_GLOBE_R2022A) layers for target years 1975-2030 (5 years timestep). This dataset contains a package composed by one excel table, a summary table gathering global summary statistics and by countries and territories in GADM3.6, and 72 CSV files, one per GADM level (from 0 to 5) and epoch (1975-2030), with all administrative units classified according to the Degree of Urbanisation. The spatial delineation of GADM 3.6 administrative units is available at GADM official website (accessible through the link below). Please select the whole world shapefile as six separate layers (one for each level of subdivision/aggregation). The vector layers can be used to join each classification table (csv) with the actual spatial units.
