The Differentiated Impact of Bridging and Bonding Social Capital on Economic Well-Being: An Individual Level Perspective
Social capital refers to trust, norms, and social networks. One of the most important features of social capital is its claimed capacity of promoting economic well-being. Theorists have assumed that any such effects vary according to the nature of different types of social capital. Using longitudinal data from a nationally representative dataset, this study investigates the differentiated effects of individual bonding and bridging social capital on subsequent personal income and income-to-needs ratios. The analyses demonstrate that bridging capital, indicated by involvement in various voluntary organizations, has small but significant effects on future economic wellbeing. However, bonding capital, indicated by connections with kin and friends as reflected through social activities, various help interactions, and perceived emergency supports, does not show such an impact. These findings lend support to the theoretical assumption that bridging capital is more effective than bonding capital in helping people advance economically. The findings have useful implications for community practice and the design of social programs
Measurement of Full-field Ductile Damage based on Resistance Method
AbstractThe measurement of damage evolution in metal materials during plastic deformation accurately and conveniently remains a challenging problem for current research. In this study, a convenient ductile damage measurement procedure is proposed. The damage value can be evaluated by continuous uniaxial tension with the digital image correlation and direct current potential drop techniques. The development of methodology and experimental setups is discussed in details. The ductile damage values obtained by the proposed approach are consistent with those obtained by the micro-hardness method. The full-field damage distribution can also be calculated besides the ductile damage evolution
The evolution of telepractice use during the covid-19 pandemic: Perspectives of pediatric speech-language pathologists
The study investigated how pediatric speech-language pathologists (SLPs) applied teleprac-tice to compensate for the loss of in-person services and the dynamics of telepractice use during the COVID-19 pandemic in a rural state. We conducted interviews with 10 SLPs and then a statewide survey in which 51 SLPs participated. The qualitative interviews revealed themes including changes in service environment due to the pandemic (e.g., transition to telepractice, losing clients), challenges in the transition to telepractice (e.g., limited training, difficulty engaging clients), worsening well-being of clinicians and clients, and SLPs’ perspectives and suggestions towards telepractice in the future. Survey results showed service disruptions and transition dynamics during the pandemic. SLPs’ weekly caseloads reduced from an average of 42.3 clients prior to the pandemic to 25.9 and 23.4 from March to May and from June to September 2020, respectively, and then recovered to 37.2 clients from October to December 2020. In contrast, the number of telepractice caseloads sharply increased from 0.2 clients per week prior to the pandemic to 14.8 from March to May 2020. The weekly telepractice caseloads then declined to 5.5 clients from June to September and 7.9 clients from October to December 2020. In the months right after the pandemic outbreak (i.e., March to May), client children struggled with treatment gains and behavioral wellbeing. However, their outcomes gradually improved by October to December and approached pre-pandemic levels. About one-third of the SLPs reported that they would be more likely or much more likely to use telepractice in the future regardless of the pandemic. However, only about a quarter perceived telepractice as comparable to in-person services. We concluded that the transition from in-person services to telepractice substantially mitigated service disruptions right after the pandemic outbreak and that telepractice’s substitute role evolved over time

Ultrasmall Glutathione-Protected Gold Nanoclusters as Next Generation Radiotherapy Sensitizers with High Tumor Uptake and High Renal Clearance
Radiotherapy is often the most straightforward first line cancer treatment
for solid tumors. While it is highly effective against tumors, there is also
collateral damage to healthy proximal tissues especially with high doses. The
use of radiosensitizers is an effective way to boost the killing efficacy of
radiotherapy against the tumor while drastically limiting the received dose and
reducing the possible damage to normal tissues. Here, we report the design and
application of a good radiosensitizer by using ultrasmall gold nanoclusters
with a naturally occurring peptide (e.g., glutathione or GSH) as the protecting
shell. The GSH coated gold nanoclusters can escape the RES absorption, leading
to a good tumor uptake (8.1% ID/g at 24 h post injection). As a result, the
as-designed Au nanoclusters led to a strong enhancement for radiotherapy, as
well as a negligible damage to normal tissues. After the treatment, the
ultrasmall gold nanoclusters can be efficiently cleared by the kidney, thereby
avoiding potential long term side effects caused by the accumulation of gold
atoms in the body. Our data suggest that the ultrasmall peptide protected Au
nanoclusters are a promising radiosensitizer for cancer radiotherapy.Comment: 15 Pages, 6 Figures, Scientific Reports 5, 201
