Social Media and Well-Being: Pitfalls, Progress, and Next Steps

This review provides an overview of the literature regarding digital technology use and adolescent well-being. Overall, findings imply that the general effects are on the negative end of the spectrum but very small. Effects differ depending on the type of use: whereas procrastination and passive use are related to more negative effects, social and active use are related to more positive effects. Digital technology use has stronger effects on short-term markers of hedonic well-being (eg, negative affect) than long-term measures of eudaimonic well-being (eg, life satisfaction). Although adolescents are more vulnerable, effects are comparable for both adolescents and adults. It appears that both low and excessive use are related to decreased well-being, whereas moderate use is related to increased well-being. The current research still has many limitations: High-quality studies with large-scale samples, objective measures of digital technology use, and experience sampling of well-being are missing. .

The impact of digital technology use on adolescent well-being .

Background Social media use (SMU) has become highly prevalent in modern society, especially among young adults. Research has examined how SMU affects well-being, with some findings suggesting that SMU is related to social anxiety and loneliness. Socially anxious and lonely individuals appear to prefer and seek out online social interactions on social media. Objective This systematic review examines social anxiety (SA) and loneliness (LO) in the context of SMU. Methods A multi-database search was performed. Papers published prior to May 2020 relevant to SMU and SA and/or LO were reviewed. Results Both socially anxious and lonely individuals engage online more problematically and seek out social support on social media, potentially to compensate for lack of in-person support. SA and LO are associated with problematic SMU; LO appears to be a risk factor for engaging problematically online. Conclusions LO is a risk factor for problematic SMU. More research on the relationship between SA and SMU is needed. To date, problematic SMU has been defined in terms of frequency rather than pattern of use. Most research has relied on self-report cross-sectional examinations of these constructs. More experimental and longitudinal designs are needed to elucidate potential bidirectional relationships between SA, LO, and SMU.

Social media use, social anxiety, and loneliness: A systematic review

Loess, which primarily consists of wind-transported silt and clay particles, is widely distributed around the world, including the central Asia, central Europe, the northwestern and central United States, Alaska, and South America. The metastable structure of natural loess has resulted in construction delays and catastrophic failures. To explore the potential applications of soil improvement with green materials, this paper presents an experimental study of applying fly ash–based geopolymers for the loess stabilization. Two different precursors are employed to the investigation. It is found that potassium hydroxide renders a higher unconfined compressive strength than sodium hydroxide to the samples when the same fly ash/loess ratio is applied. This agrees with the results of the mechanical properties of the two different geopolymers. With an increasing fly ash/loess ratio, the compressive strength and Young’s modulus increase. The microstructural characterization unveils that a compact and stable...

This paper describes the results of a detailed analysis of a loess deposit at the deep foundations test site established by the Kansas Department of Transportation Multiple CPT, SPT, and pressuremeter tests were conducted as part of the investigation This paper includes an evaluation of the effectiveness of common correlations used with the CPT, SPT when used for classification of loess and estimating its properties Results show that common correlations must be used with caution as significant errors in estimation may result from using methods developed for other soil types Laboratory testing included direct shear, triaxial, collapse, and consolidation testing, with many of the tests conducted on both vertically and horizontally oriented samples to evaluate anisotropic behavior The results showed that strength properties could be considered to be isotropic

Characterization of Loess for Deep Foundations

Lateral loads on drilled shafts are often the controlling factor in their design. These lateral loads are transferred to the surrounding soil or rock, and estimation of the capacity of the shaft to resist lateral loads is a critical part of the design. The lateral load-deformation relationship of a drilled shaft and its supporting soil is commonly modeled using the p-y curve method. P-y curves vary with soil type, deposition characteristics and depth, but general curves have been developed to represent common soils. Unfortunately, no p-y curves have been developed to represent the behavior of loess, cemented silt that is common throughtout much of Kansas. This lack of available p-y relationships has meant that less applicable curves, normally those for sandy soils, must be used. The purpose of this research was to define the significant engineering properties of Kansas' loessal soils through a literature review, laboratory tests, and in situ tests and to determine the soil-structure response by performing full scale lateral load tests on six drilled shafts. Laboratory testing included saturated and unsaturated triaxial, direct shear, consolidation and collapse testing. Field tests included standard penetration tests (SPT), cone penetration tests (CPT), vane shear, and pressuremeter testing. Two pairs of shafts with diameters of 30 and 42 in. were tested under static loading. A third pair of 30 in. shafts was tested under repeated loading. Shaft deflections were measured using inclinometer soundings and correlated with the CPT cone tip resistance (q sub c). A hyperbolic model was developed to correlate ultimate soil resistance (P sub uo) to the CPT cone tip resistance (q sub c) for both static and repeated loading at any given depth and was used to develop a family of p-y curves unique to loess. This model may be entered into the commercially available software package LPILE for design of laterally loaded drilled shafts constructed in loess.
