In developing countries, labor out-migration has led to millions of married couples living apart from each other. Male out-migration brings economic benefits to the families in places of origin, but also leads to profound changes in the lives of the left-behind wives. It is unclear how the husband's out-migration influences the health of wives, let alone the mechanisms through which any effects are transmitted. Using data from the Indian Human Development Survey (2004-2005 and 2011-2012), we estimated lagged dependent variable models (N = 19,737) to assess the health impact of husbands' out-migration for women in India. The results showed that left-behind wives had lower self-rated health than wives of non-migrants. Part of this negative health impact was driven by the low remittances sent by the migrant husbands. For both women in nuclear families and women in extended families, the negative health impact was partially attributable to women's added responsibilities, such as animal care and managing a bank account. For women in nuclear families, the negative health effect of husbands' migration has been partially suppressed by women's increased autonomy.

Conspiracy theories about COVID-19 pose a serious threat to public health by providing false information and undermining official health recommendations. However, existing studies rarely employed longitudinal designs, precluding the determination of the directionality between endorsement of conspiracy theories and its societal consequences. Abemaciclib Also, relatively little research examined whether the association between protective health behaviour and the endorsement of conspiracy theories is affected by the content of a given theory.

A four-wave longitudinal panel survey on the association between belief in a wide range of conspiracy theories about COVID-19 and protective behaviour was carried out on a representative sample of Polish citizens (T1 = 1130, T2 = 971, T3 = 818, T4 = 688). Analyses were performed using Random Intercept Cross-Lagged Panel Models.

The results showed a reciprocal, bidirectional association between conspiracy mentality and protective behaviour. The same effect was also observed betweehe government may limit civil rights. Specific conspiracy beliefs were significantly related to protective behaviour only at the between-person level.Through a two-way control of hexadecyl trimethyl ammonium bromide (CTAB) and hydrochloric acid (HCl), the PdCu nanoalloys with branched structures are synthesized in one step by hydrothermal reduction and used as electrocatalysts for formic acid oxidation reaction (FAOR). In this two-way control strategy, the CTAB is used as a structure-oriented surfactant, while a certain amount of HCl is used to control the reaction kinetics for achieving gradual growth of multi-dendritic structures. The characterizations including scanning transmission electron microscope (STEM), X-ray powder diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) suggest that PdCu nanoalloys with unique multi-dendritic branches have favorable electronic structure and lattice strain for electrocatalyzing the oxidation of formic acid. In specific, among the electrocatalysts with different Pd/Cu ratios, the Pd1Cu1 branched nanoalloys have the largest electrochemically active surface area (ECSA) and the best performance for the FAOR. The catalytic activity of the Pd1Cu1 branched nanoalloys is 2.4 times that of commercial Pd black. After the chronoamperometry test, the Pd1Cu1 branched nanoalloys still maintain their original morphologies and higher current density than that of the commercial Pd black. In addition, in the CO-stripping tests, the initial oxidation potential and the oxidation peak potential of the PdCu branched nanoalloys for CO adsorption are lower than those of commercial Pd balck, evincing their better anti-poisoning performance.Electrocatalysts for water splitting have been widely explored among recent years. In this study, nickel-selenium-copper (Ni-Se-Cu) coating was synthesized on nickel foam through potentiostatic electrodeposition. The electrochemical kinetics and nucleation mechanisms of the deposition were investigated, and the diffusion coefficient D from different deposition potentials and temperatures was calculated. Results reveal that the electrodeposition of Ni-Se-Cu follows an instantaneous nucleation and diffusion-controlled three-dimensional (3D) growth mechanism. Deposition potential and bath temperature slightly effect the nucleation mechanism of electrodeposition. The apparent activation energy Ea of the hydrogen evolution reaction (HER) in 1.0 M KOH electrolyte of Ni-Se-Cu is 21.1 kJ·mol-1, which is lower than that of Ni-Se (37.7 kJ·mol-1). The majority phase formed by nickel and selenium is Ni3Se2, and a Ni(Cu) solid solution forms after the incorporation of Cu atoms into a Ni lattice.Peroxymonosulfate (PMS) activation by heterogeneous transition metal oxides is an effective approach for treating emerging pollutants in water. However, the low PMS activation efficiency associated with the valency conversion rate of transition metals has been a major challenge to sulfate radical-based oxidation. In this work, manganese cobaltate (MnCo2O4) nanoparticles anchored on graphitic carbon nitride (g-C3N4) flakes (MnCo2O4/g-C3N4) were successfully prepared and showed high PMS activation efficiency under visible (Vis) light. The obtained catalysts degraded 96.1% of the tetracycline hydrochloride (TCH) through the synergistic effect of PMS and photocatalysis. The reaction rate constant (0.2505 min-1) was 5.3 and 1.8 times higher in the MnCo2O4/g-C3N4/PMS/Vis system than in the pristine g-C3N4 (0.0471 min-1) and MnCo2O4 (0.1435 min-1) systems, respectively. The characterization results verified that g-C3N4, which functions as the electron donor in the photocatalytic heterojunction system, could transmit numerous photogenerated electrons to MnCo2O4, thereby increasing the cyclability of divalent-trivalent metal ions. The composites also showed good stability, cycling capability, and cation/anion tolerance. Tentative degradation mechanism and reaction pathways were proposed based on the reactive species and degradation products.
