This paper examines whether different types of intergenerational support have different effects on life satisfaction among the elderly, and whether a gender difference exists in the effect of intergenerational support on the elderly’s life satisfaction. Data from the China Longitudinal Aging Social Survey (CLASS) were used for this study. The study sample consisted of 10,801 cases. A logit regression model was used for empirical verification. All types of intergenerational support were found to have effects on life [...]

Loneliness, social isolation, aloneness, and solitude may be used interchangeably by some who may miss the difference between them. Loneliness is the experience of being alone, or perceiving that one is alone and unimportant to others. Solitude is being geographically isolated out of one’s choice. Loneliness is not a feeling, but a multidimensional construct which is expressed cognitively, behaviorally and affectively. solitude is also reviewed and a clear distinction between loneliness and solitude is established.

In this paper, an efficient industrial wastewater and leachate evaporation method is proposed and tested experimentally. The goal of this study is to investigate whether the addition of a carbon foam (CF) porous layer can lead to energy savings by evaporating more water mass per unit of energy input. The standard boiling evaporator layout was redesigned by placing the heating element in the upper region of the tank and CF underneath the heat source. The CF purposed to localize the energy in an area by the water' [...]

We have investigated the utility of the 5S nrDNA, a conserved, multicopy gene family organized into tandem repeats as a tool for genetic analyses in a wide variety of genera. Previous work in the Triticeae (Poaceae) demonstrated that the prior identification of unit classes based upon the 5S nrDNA NTS, greatly facilitates analysis. We investigated the potential of defining unit classes in other plant genera and several animal genera as a step towards future phylogenetic analyses. Our results demonstrate that in in [...]

By using long pulses with extended dwelling time, lowered pulse repetition frequency (PRF) and reduced Nyquist velocity, the radar measurement capability can be enhanced to increase clear-air Doppler velocity data coverage (which is beneficial for radar wind analysis and data assimilation and motivated our previous study). This potential capability is further explored (beyond our previous study) by not only modifying the existing operational clear-air scan mode with a lowered PRF and reduced the Nyquist velocity (t [...]

The compound, [cis-dichloro-(tris-2-amino(ethylamine))cobalt(III)]chloride hydrate, [cis-Cl2-(tren)Co(III)Cl]·H2O, a conglomerate crystallizing in P21 with Z = 4 (Z’ = 2), has been used as a precursor in the synthesis of a new dicobalt(III) peroxo complex: [(μ2-hydroxo)(μ2-peroxo)bis(tris-2-amino(ethylamine))di-cobalt(III)] tris(triiodide) dihydrate. This material crystallizes, without disorder, in space group P212121 with Z = 4 (Z’ = 2), thus making it, unambiguously, an example of a conglomerate. Its cell constan [...]

Due to its similar characteristics to titanium, niobium has become an attractive alternative in photocatalytic processes. Research indicates that titania has an optimal percentage of phases resulting in a commercial catalyst, P25, that contains more than 70% anatase with a minor amount of rutile and a small amount of amorphous phase. On the other hand, for Nb2O5, percentage optimization was little explored in the literature, which consists of studying the phases obtained via heat treatment individually and in diffe [...]

The prevalence of alcohol use disorder (AUD) and alcohol-related liver disease (ALD) has increased in the last two decades. ALD is currently the most common indication for both waitlist additions and liver transplant (LT) in the United States, including alcohol-associated cirrhosis, alcohol-associated hepatitis (AH), and acute-on-chronic liver failure (ACLF). ALD also has a significant global disease burden. LT in ALD is a complex paradigm that poses both medical and ethical challenges, requiring a multidisciplinar [...]

Lesbian, gay, and bisexual (LGB) older adults may be more vulnerable to elder abuse (EA) due to prior marginalization and trauma, lifelong discrimination, and health disparities. While characteristics of both victims and perpetrators can modify the risk for EA, few studies have focused on perpetrators. This study examined the number and type of perpetrator-victim relationships and perpetrator profiles for EA experienced in the prior year, by abuse type and sexual orientation and gender identity of the abused. Data [...]

The increasing number of biogas plants with various digested organic materials and output of digestates calls for more detailed investigations of their suitability as soil amendments. In a trial in Northern Germany two replicate plots each were treated with fresh or prolonged fermented digestate to investigate the influence of digestates on the composition of soil organic matter (SOM). The relative proportions of relevant SOM compound classes were determined by pyrolysis-field ionization mass spectrometry (Py-FIMS) [...]
