Using List Prices to Collude or to Compete?
Authors: Cussen Diego , Montero Juan-Pablo 
Published: June 2024

Abstract
Collusion is deemed unlikely in wholesale markets where upstream suppliers and intermediate buyers privately negotiate discounts off list prices and sales quotas are unfeasible. However, many wholesale markets include both small and large buyers who compete in the retail market. We study the role of publicly announced list prices in this wholesale-retail setting, whether suppliers collude or compete. When suppliers collude, public announcements of list prices extend the possibility of collusion from small to large buyers (the multi-buyer contact effect). When suppliers compete, these announcements provide them with commitment to negotiate better terms with large buyers (the commitment effect).
Church Membership and Economic Recovery: Evidence from the 2005 Hurricane Season
Authors: Hasan Iftekhar , Manfredonia Stefano , Noth Felix 
Published: June 2024

Abstract
This paper investigates the critical role of church membership in the process of economic recovery after high-impact natural disasters. We document a significant adverse treatment effect of the 2005 hurricane season in the Southeastern United States on establishment-level productivity. However, we find that establishments in counties with higher rates of church membership saw a significantly stronger recovery in terms of productivity for 2005–10. We also show that church membership is correlated with post-disaster entrepreneurship activities and population growth.
Comparing Neighbors and Friends in Age-Related Network Changes
Authors: Kalmijn Matthijs 
Published: June 2024

Abstract

Objectives
To assess how the role of neighbors and friends in people’s networks changes with age and how this is affected by cohort, marriage, employment, and socioeconomic status. The hypothesis is that for most aspects of the network, friends lose “importance” as people become older, with neighbors gradually becoming more dominant in the nonkin network.

Methods
Data are used for people aged 55–90 between 1999 and 2019 from the Swiss Household Panel (N = 5,585). A total of 4 network aspects were measured: size, contact, practical support, and emotional support. Measures for neighbors and friends were compared and analyzed with fixed-effects and hybrid-effects regression models on person-year observations.

Results
The sizes of both network segments declined with age but more strongly for friends than neighbors. Contact with friends was stable but contact with neighbors increased. Support from friends declined whereas support from neighbors was stable. Direct comparisons revealed that the relative share of neighbors vis-à-vis friends increased as people age. Friends were more common and supportive vis-à-vis neighbors for divorced and widowed people than for married people, but this gap declined with age. The share of neighbors increased with retirement, especially for men. The share of neighbors vis-à-vis friends was also larger for people with less income and education and this gap did not change with age.

Discussion
In the nonkin part of older adults’ networks, proximity eventually becomes dominant. This finding is interpreted in terms of rising needs, greater opportunity for local contact, and friend mortality risks, all favoring the neighbor segment of the network.
Life Events and Incident Dementia: A Prospective Study of 493,787 Individuals Over 16 Years
Authors: Karakose Selin , Luchetti Martina , Stephan Yannick , Sutin Angelina R , Terracciano Antonio 
Published: June 2024

Abstract

Objectives
Life events can be stressful and have a detrimental impact on health, but evidence is inconclusive regarding life events and dementia risk. The present study tests whether life events are associated with incident dementia, whether experiencing multiple events has cumulative effects, and whether the associations vary across age, sex, race/ethnicity, socioeconomic status, and genetic vulnerability.

Methods
UK Biobank participants (N = 493,787) reported on 6 life events that occurred within the past 2 years: serious illness, injury, assault to yourself or close relative, death of a spouse/partner or close relative, marital separation/divorce, and financial problems. Incident all-cause dementia was ascertained through health records from the UK National Health Service over a 16-year follow-up.

Results
Serious illness, injury, or assault to yourself, marital separation/divorce, and financial difficulties were associated with a higher risk of dementia; serious illness, injury, or assault of a close relative was associated with a lower risk of dementia. When combined, experiencing 3–4 events was associated with a more than 2-fold increase in dementia risk. The association for marital separation/divorce was stronger within the first 5 years of follow-up (consistent with reverse causality). Death of a spouse/partner or close relative was mostly unrelated to dementia risk. With few exceptions, the associations were similar across age, sex, race/ethnicity, socioeconomic status, and apolipoprotein E e4 status groups.

Discussion
Severe illness, injury, or personal assault, marital separation or divorce, and financial hardships may raise risk of dementia, particularly when these events occur together.
Beyond the focus on individuals: Adding environment into the redefined successful aging paradigm
Authors: Zhuo Li , Cao Jiawei 
Published: June 2024

Abstract
Since the origin of the Successful Aging (SA) model by Rowe and Kahn, scholars have been working on enriching the content of SA and taking actions to promote this concept worldwide. While most studies primarily focus on older individuals, only a few scholars have considered the environmental aspect of SA. However, the environment, directly and indirectly, enhances older adults’ abilities to achieve SA. To measure SA comprehensively and address inequalities among older adults, this theoretical article aims to challenge current SA models by incorporating both individual and environmental aspects and proposing four measurement dimensions: inclusivity of disadvantaged groups, culture-specific adaptation, balance between physical and social environments, and dynamics of the whole lifecycle. Moreover, this article provides examples to illustrate how environment can support older adults especially those who would be defined as “unsuccessful” under the original SA model. Our proposed model would provide theoretical guidance for future research and spark new ideas for policies and programs that support every older adult in achieving SA.
Brief Aging Education Affects Continuing Education Preferences and Behaviors of Mental Health Providers
Authors: Schmidt Nicholas E , Carpenter Brian , Steffen Ann M 
Published: June 2024

Abstract

Background and Objectives
This study examined the impact of receiving foundational information about aging on continuing education (CE) interests, preferences, and behaviors of mental health providers.

Research Design and Methods
Participants were practicing licensed professional counselors (N = 120) recruited from a random sampling of a state registry. The study employed a 3-group randomized controlled design with participants assigned to 1 of 3 conditions: an aging-specific reading, an opioid use disorder-specific reading, and a CE requirement-specific reading. As outcomes, participants rated their interest in aging-specific CE and selected to receive an aging-specific CE or Motivational Interviewing-specific CE program.

Results
Perceived competence for working with older adults, assessed before the experimental manipulation, predicted choice and degree of interest in the aging-specific CE across conditions. Participants in the Aging-Reading condition rated a higher interest in aging-specific CE and were marginally more likely to select the aging-specific CE option than those in the other 2 conditions. Those in the Aging-Reading condition were also more likely to register for and complete an actual CE program focused on any topic.

Discussion and Implications
Foundational knowledge about aging may increase practitioners’ interest and behaviors toward gaining competency for working with older adults, supporting the Positive Education about Aging and Contact Experiences model (Levy, S. R. (2018). Toward reducing ageism: PEACE (positive education about aging and contact experiences) model. Gerontologist, 58(2), 226–232. https://doi.org/10.1093/geront/gnw116) of reducing ageism.

Published: June 2024

Abstract

Background and Objectives
This study examined the psychometric properties and measurement invariance of the 10-item Awareness of Age-Related Change Short Form (AARC-SF) questionnaire in a Chinese-speaking sample of older adults in Taiwan.

Research Design and Methods
Data from 292 participants (Mage = 77.64 years) in the Healthy Aging Longitudinal Study in Taiwan cohort were used for Study 1, whereas data from young-old adult samples in Germany were used for Study 2.

Results
Study 1 showed that the AARC-SF had satisfactory reliability and validity for assessing adults’ AARC in Taiwan. Analyses confirmed the 2-factor structure of AARC-gains and AARC-losses. Study 2 demonstrated strong measurement invariance across men and women, whereas direct comparisons of the item scores between young-old adults and old-old adults need to be made with caution. Noninvariance of loadings indicated that certain items were more closely linked to AARC-gains and AARC-losses in Taiwan than in Germany. Noninvariance of intercepts suggested potential biases in comparing item scores between Taiwanese and German older adults.

Discussion and Implications
The AARC-SF emerged as a reliable and valid instrument for capturing positive and negative subjective aging experiences among Taiwanese older adults. However, it is noteworthy that some items on the AARC-SF may solicit different responses from individuals of different ages and different countries of origin, requiring caution with age group and cross-cultural comparisons.
Present day mantle structure from global mantle convection models since the Cretaceous
Authors: Pal Debanjan , Ghosh Attreyee 
Published: June 2024

SUMMARY
Using forward mantle convection models starting at 140 Ma, and assimilating plate reconstructions as surface velocity boundary condition, we predict present-day mantle structure and compare them with tomography models, using geoid as an additional constraint. We explore a wide model parameter space, such as different values of Clapeyron slope and density change across 660 km, density and viscosity of the thermochemical piles at the core–mantle boundary (CMB), internal heat generation rate, and model initiation age. We also investigate the effects of different strengths of a weak layer below 660 km and weaker asthenosphere and slabs. Our results suggest that slab structures at different subduction zones are sensitive to the viscosity of the asthenosphere, strength of slabs, values of Clapeyron slope and the density and viscosity of the thermochemical piles, while different internal heat generation rates do not affect the slab structures. We find that with a moderately weak asthenosphere ($10^{20}$ Pa·s) and strong slabs, the predicted slab structures are consistent with the tomography models, and the observed geoid is also matched well. Moreover, our models successfully reproduce the degree-2 structure of the lower mantle beneath Africa and the Pacific, also known as Large Low Shear Velocity provinces (LLSVPs). A moderate Clapeyron slope of −2.5 MPa K−1 at 660 km aids in slab stagnation while higher values result in massive slab accumulation at that depth, ultimately leading to slab avalanches. We also find that the convective patterns in the thermal and thermochemical cases with slightly denser LLSVPs are similar, although the geoid amplitudes are lower for the latter. However, with more dense LLSVPs, the slabs cannot perturb them and no plumes are generated. Plumes arise as thermal instabilities from the edges of the LLSVPs, when cold and viscous slabs perturb them. While our predicted plume locations are consistent with the observed hotspot locations, matching the plume structures in tomography models is difficult. These plumes are essential in fitting the finer features of the observed geoid. In longer-duration models, more voluminous subducted material reaches the CMB, which tends to erode the LLSVPs significantly, and yields a poor fit to the observed geoid. Our results suggest that with the presence of a thin, moderately weak layer below 660 km, a slightly dense LLSVP, and Clapeyron slope of −2.5 MPa K−1, the velocity anomalies in seismic tomography and the long-wavelength geoid can be matched well. One of the limitations of our models is that the assimilated plate motion history may be too short to overcome arbitrary initial conditions effects. Also, assimilated true plate velocities in our models may not represent the true convective vigour of the Earth.
Clonal spread of blaNDM-1-carrying Salmonella enterica serovar Typhimurium clone ST34 and wide spread of IncHI2/ST3-blaNDM-5 plasmid in China
Authors: Deng Limin , Lv Lu-Chao , Tu Jieying , Yue Chao , Bai Yuman , He Xiaotong , Liao Min , Liu Jian-Hua 
Published: June 2024

Abstract

Objectives
To characterize blaNDM-carrying Salmonella recovered from a pig slaughterhouse.

Methods
In this study, 46 environment samples were collected from a slaughterhouse in China, and screened for carbapenem-resistant Enterobacterales. WGS, antimicrobial susceptibility testing and conjugation experiments were carried out to identify the isolates’ resistance phenotypes and genetic characteristics. The phylogenetic relatedness of the Salmonella isolates obtained in this study and Salmonella (ST34 and ST29) in GenBank was determined.

Results
Two ST34 Salmonella Typhimurium and one ST29 Salmonella Stanley, recovered from three environmental samples (6.52%), were positive for blaNDM-1 and blaNDM-5, respectively. The two ST34 S. Typhimurium strains exhibited a close relationship (10–36 SNPs) with two human-derived blaNDM-1-bearing isolates from China (Hong Kong and Guangxi Province) and two blaNDM-negative ST34 Salmonella strains from the UK. The blaNDM-1 genes were located on IncHI2/ST3 plasmids. The capture of blaNDM-1 by the IncHI2/ST3 plasmid seems to be due to homologous recombination mediated by circular structures, as the genetic arrangements of the blaNDM-1 gene contain two IS26 elements of the same orientation. The blaNDM-5 gene was also carried by the IncHI2/ST3 plasmid, which shares highly similar structures with other blaNDM-5-bearing IncHI2/ST3 plasmids from other sources (fish, chicken, duck, human).

Conclusions
This is the first report of a blaNDM-5-carrying IncHI2/ST3 plasmid in Salmonella. The clonal spread of NDM-1-producing ST34 S. Typhimurium across human and animal-associated environments, and the widespread dissemination of epidemic blaNDM-5-carrying IncHI2/ST3 plasmids among Enterobacteriaceae in China indicate the potential of further dissemination of blaNDM among Salmonella, which poses a threat to public health.
In vitro and intracellular activity of vaborbactam combined with β-lactams against Mycobacterium abscessus
Authors: Sanchez Léa , Bitar Maria , Herail Quentin , Dorchêne Delphine , Hugonnet Jean-Emmanuel , Arthur Michel , Mainardi Jean-Luc 
Published: June 2024

Abstract

Objectives
Mycobacterium abscessus has emerged as an opportunistic pathogen responsible for lung infections, especially in cystic fibrosis patients. In spite of the production of the broad-spectrum β-lactamase BlaMab, the carbapenem imipenem is recommended in the initial phase of the treatment of pulmonary infections. Here, we determine whether the addition of vaborbactam, a second-generation β-lactamase inhibitor belonging to the boronate family, improves the activity of β-lactams against M. abscessus.

Methods
The activity of β-lactams, alone or in combination with vaborbactam, was evaluated against M. abscessus CIP104536 by determining MICs, time-killing and intramacrophage activity. Kinetic parameters for the inhibition of BlaMab by vaborbactam were determined by spectrophotometry.

Results
The combination of vaborbactam (8 mg/L) with β-lactams decreased more than 8 times the MIC of amoxicillin (from &gt;1024 to 128 mg/L) and 2 times the MICs of meropenem (from 16 to 8 mg/L) and imipenem (from 4 to 2 mg/L). The reduction of the MICs was less than that obtained with avibactam at 4 mg/L for amoxicillin (from &gt;1024 to 16 mg/L, more than 64 times less) and for meropenem (from 16 to 4 mg/L, 4 times less). In vitro and intracellularly, M. abscessus was not killed by the meropenem/vaborbactam combination, in spite of significant in vitro inhibition of BlaMab by vaborbactam.

Conclusions
Inhibition of BlaMab by vaborbactam decreases the MIC of β-lactams, including that of meropenem. As meropenem/vaborbactam is clinically available, this combination offers an alternative therapeutic option that should be evaluated for the treatment of pulmonary infections due to M. abscessus.
Effects of feeding different dietary rates of mixed fodder beet tops-wheat straw silage on the performance of Holstein lactating cows

Published: June 2024

Abstract
Rations containing different rates of the mixed fodder beet tops-wheat straw silage (BS), instead of corn silage (CS), were given to 30 mid-lactation Holstein cows (all in parity 2) to measure the effects on feed consumption, milk production efficiency, milk chemistry, urinary purine derivatives (PD), blood chemistry, antioxidant levels, and in vitro methane (CH4) emission. The BS was prepared by mixing the fodder beet tops with wheat straw at a ratio of 9:1 based on fresh weight. The experimental design was completely randomized (one 28-d period with 21-d adaptation) using 30 cows (10 animals/treatment) and 3 treatments. The treatments were 1) a diet containing CS only (25 g/100 g DM) (CSD), 2) a diet containing 50% CS (12.5 g/100 g DM) and 50% BS (12.5 g/100 g DM) (CBSD), and 3) diet containing BS only (25 g/100 g DM) (BSD). Each animal (as an experimental unit) was housed individually in the tie stall and had ad libitum access to its diet. Dietary replacing 50% of CS with BS showed no significant differences in milk production, fat-corrected milk, fat and protein yields, feed efficiency, and apparent digestibility, however, these variables were less (P &lt; 0.05) in the cows fed with BSD. Cows fed on BSD had less intakes of DM, organic matter, crude protein, and neutral detergent fiber but greater oxalic acid intake and blood urea-N, as compared to the other cows. Milk percentages of fat, protein, lactose, urea N, blood serum glucose, triglyceride, cholesterol, total protein, albumin, globulin, Ca, and P, as well as in vitro ruminal pH, were not affected by the diets. Saturated fatty acids concentration was less and monounsaturated FA and polyunsaturated FA (PUFA) was greater in the milk of cows receiving CBSD, compared to the other groups. The inclusion of both BS rates in the diet decreased the in vitro gas production, protozoa number, and CH4 emission in comparison to the control. Cows fed BSD had decreased levels of urinary allantoin, PD excreted or absorbed, and estimated microbial-N synthesis than the control and CBSD-fed groups. The milk and blood total antioxidant capacity (TAC) of the animals fed CBSD was the maximum among the cows. Overall, under the current experimental conditions, replacing 50% of dietary CS with BS did not affect milk production, but increased milk PUFA, as well as blood and milk TAC, and decreased in vitro CH4 emission, so it’s feeding to lactating Holstein cows is recommended.

Abstract
Burn survivors can experience social participation challenges throughout their recovery. The aim of this study was to develop a novel Australian English translation of the Life Impact Burn Recovery Evaluation (LIBRE) Profile, the Aus-LIBRE Profile. This study consisted of 3 stages: (1) translation of the LIBRE Profile from American to Australian English by Australian researchers/burns clinicians, (2) piloting and cognitive evaluation of the Aus-LIBRE Profile with burn survivors to assess the clarity and consistency of the interpretation of each individual item, and (3) review of the Aus-LIBRE Profile by colleagues who identify as Aboriginal Australians for cross-cultural validation. In stage 2, investigators administered the translated questionnaire to 20 Australian patients with burn injuries in the outpatient clinic (10 patients from Victoria and 10 patients from Western Australia). Face validity of the Aus-LIBRE Profile was tested in 20 burns survivors (11 females) ranging from 21 to 74 years (median age 43 years). The total body surface area burned ranged from 1% to 50% (median 10%). Twelve language changes were made based on the feedback from the burn clinicians/researchers, study participants, and colleagues who identify as Aboriginal Australians. Using a formal translation process, the Aus-LIBRE Profile was adapted for use in the Australian burn population. The Aus-LIBRE Profile will require psychometric validation and testing in the Australian patient with burns population before broader application of the scale.
The FDA Enhancing Quality Using the Inspection Program (EQUIP) Breast Imaging Quality Initiative. 5-Year Clinical Experience
Authors: Hawley Jeffrey R , Ha Cynthia , Cai Linda , Taylor Clayton R 
Published: June 2024

Abstract

Objectives
To evaluate the effects of the Enhancing Quality Using the Inspection Program (EQUIP) on quality control (QC) and quality assurance (QA) at an academic medical center.

Methods
EQUIP audit logs for technologist image quality review as well as mammography unit QA and QC formed the basis for study data. One randomly selected screening mammogram was evaluated by the lead interpreting physician (LIP) using EQUIP criteria for each technologist for each imaging site worked, initially semiannually and then monthly. One randomly selected screening mammogram interpreted by each interpreting physician (IP) for each imaging site was evaluated on a semiannual basis. Quarterly, the LIP reviewed QA and QC logs for each mammography unit with deficiencies further investigated.

Results
Of 214 965 eligible screening mammograms performed, 5955 (2.8%) underwent EQUIP image quality review. Five were found to be technically inadequate (0.08%, 5955/214 965). The LIP identified 20 significant interpretive differences compared with the clinical interpretation resulting in 10 biopsies and 7 previously undetected malignancies, with supplemental cancer detection rate of 1.2/1000 cases reviewed. Two hundred ninety mammography unit QA/QC reviews identified 31 potential deficiencies, 29 of which were due to human documentation error (93.4%).

Conclusion
EQUIP review of both IP and technologists’ quality and mammography unit QA/QC logs as performed identified few deficiencies. EQUIP policies should be evaluated at each institution and modified to best utilize resources and provide opportunities for meaningful quality improvement. Although not an EQUIP focus, supplemental cancer detection was observed as might be expected with double reading.
