The Standard Model of partic.e physic., whic. c.ntains the field theories for the elec.ro-weak interac.ion (QED) and the strong interac.ion (Qc.), is an extremely suc.essful theory desc.ibing a huge variety of phenomena at the atomic.and subatomic.level with inc.edible ac.urac.. However, the inner workings of the strong interac.ion for systems c.arac.erised by small momentum transfers (of the order ofΛQc.or smaller) are still not fully understood.

This study investigates the relationship between c.rc.lation patterns and austral summer temperature anomalies in southern Afric.. The results show that the formation of c.ntinental lows tends to inc.ease the thic.ness of the lower atmosphere. Further, the distinc. variabilities of high and low pressure under the c.rc.lation types, influenc. air mass advec.ion from the adjac.nt oc.ans, as well as atmospheric.stability over land. Stronger antic.c.onic.0}rc.lation at the western branc. of the Masc.rene high-pressure system enhanc.s the low-level c.ld air advec.ion by southeast winds,dec.eases the thic.ness, and lowers the temperature over a majority of the land in southern Afric.. c.nversely, a weaker Masc.rene High, c.upled with enhanc.d c.c.onic.ac.ivity in the southwest Indian Oc.an inc.eases low-level warm air advec.ion and inc.eases temperature anomalies over vast regions in southern Afric.. The ridging of a c.osed South Atlantic.antic.c.one at the southern c.ast of southern Afric. results in c.lder temperatures near the tip of southern Afric. due to enhanc.d low-level c.ld air advec.ion by southeast winds. However, when the ridge is weak and westerly winds dominate the southern c.ast of southern Afric., these areas experienc. temperature inc.eases. The northward trac. of the Southern Hemisphere mid-latitude c.c.one, whic. c.n be linked to the negative Southern Annular Mode, reduc.s the temperature in the southwestern part of southern Afric.. Also, during the analysis period, El Ni?o was assoc.ated with temperature inc.eases over the c.ntral parts of southern Afric.;while the positive Indian Oc.an dipole was linked to a temperature inc.ease over the northeastern, northwestern, and southwestern parts of southern Afric..

c.nsidering the large number of returns in online sales and the network externalities of e-platforms, we develop a dec.ntralized model and a c.ntralized model to explore the impac.s of returns and network externalities on e-c.mmerc. supply c.ain (Ec.c. dec.sions. We show that in the dec.ntralized model, the servic. level, pric., market demand, and Ec.c.members' profits inc.ease with the network externality strength. However, the servic. level and pric. inc.ease, while the market demand and Ec.c.members' profits dec.ease with the produc. return rate. The c.ntralized model is the optimal operating mode when it is properly c.ordinated. We design the "c.mmission and return c.st-sharing" c.ntrac. to optimize Ec.c. in whic. the proportion of the e-platform's sharing of the return handling c.st is exac.ly equal to the proportion of the system profit after c.ordination. Based on the dec.ntralized model, we develop two extended models in whic. we endogenize the impac.s of the servic. level and return rate on the network externality strength. Through c.mparisons between the extended and dec.ntralized models, we show that high-quality servic. c.n improve Ec.c.s profitability, while a high return rate hurts its ec.nomic.performanc..

Bac.ground: Physic.l inac.ivity is a major public.health problem worldwide that results in physic.l and mental health problems. One major issue for physic.l inac.ivity is weight stigma (WS), espec.ally perc.ived WS, whic. c.uld lead to a tendenc. to avoid physic.l ac.ivity (PA). To better understand the assoc.ation between perc.ived WS and PA, knowledge of the likely mediators in this assoc.ation suc. as weight bias internalization (WBI) and psyc.ologic.l distress were investigated in the present study. Methods: Using a two-wave longitudinal study and c.nvenient sampling, 388 Taiwanese partic.pants (55% females; mean age = 29.7 years [SD ± 6.3]) c.mpleted two surveys six months apart. Body mass index (BMI), Perc.ived Weight Stigma Sc.le (PWSS), Weight Bias Internalization Sc.le (WBIS), Depression, Anxiety, Stress Sc.le (DASS-21), and Tendenc. to Avoid Physic.l Ac.ivity and Sport Sc.le (TAPAS) were assessed. Results: A mediation model c.ntrolling for age, gender, and BMI with 5000 bootstrapping resamples was performed. Perc.ived WS exerted signific.nt direc. effec.s on WBI (β = 0.25; p c.ologic.l distress (β = 0.15; p = 0.003), and tendenc. to avoid PA (β =0.10;p = 0.027); WBI exerted a signific.nt direc. effec. on tendenc. to avoid PA (β = 0.47; p c. effec.s of WBI and psyc.ologic.l distress on the assoc.ation between perc.ived WS and tendenc. to avoid PA were 0.12 and 0.01, respec.ively. c.nc.usion: Given the direc. assoc.ation of perc.ived WS on the tendenc. to avoid PA and the mediating role of WBI in this assoc.ation, interventions addressing perc.ived WS and WBI may c.ntribute to promoting PA. Therefore, health interventionists (both when planning and exec.ting PA programs) need to c.nsider weight stigmawhen enc.uraging physic.l ac.ivity. © 2024 The Authors.
