Childhood Hearing Impairment, Gender, and Trait Neuroticism as Independent Predictors of the Occurrence of Hearing Problems in Adulthood

The possible association between personality and hearing problems may occur for various reasons. Personality traits may manifest themselves in a lifestyle that can adversely affect hearing. Equally early hearing loss could affect personality development. This study explored psychological, biomedical, and social factors in childhood and adulthood associated with the occurrence of self-reported hearing problems in adulthood.

In total, 4828 participants with complete data on parental social class at birth, childhood hearing impairment measured at age 7 years and cognitive ability accessed at age 11 years, educational qualifications obtained at age 33 years, the Big-Five-Factor personality traits measured at age 50 years, current occupational levels and self-reported hearing problems at age 54 years were included in the study. The authors first examined the characteristics of the study population. Second, correlation matrix of all the variables used in the study was examined. Third, they carried out the logistic regression analysis using STATA version 14 using self-reported hearing problems in adulthood as the dependent variable.

Descriptive analysis showed that cohort members who had professional or managerial family background and had highest educational qualification (university degree) with current professional occupation tended to report less hearing problems. There were also sex differences: men reported more than women on hearing problems (12.7% and 7.9% respectively). Also, participants who had hearing impairment in childhood were more likely to have hearing problems in adulthood. Parental social class, current occupational levels, personality traits Emotional Stability (low Neuroticism) and Conscientiousness as well as gender were all statistically significantly associated with the occurrence of hearing problems in adulthood (p < 0.05 to p < 0.001).

Logistic regression analysis showed that among all psychological, biomedical and socio-demographic factors in childhood and adulthood examined, gender, childhood hearing impairment, and trait Neuroticism were the only significant and independent predictors of the outcome variable.

In conclusion, this study showed there were few demographic or personality trait predictors of adult hearing problems. Indeed, the only correlate in the data was trait Neuroticism, or low Emotional Stability which inevitably might have been affected by a lifetime of communication difficulties associated with hearing impairment of many kinds.

A Comparison of Methods Used to Determine the Oleic/Linoleic Acid Ratio in Cultivated Peanut (Arachis hypogaea L.)

Cultivated peanut ( Arachis hypogaea L.) is an important oil and food crop. It is also a cheap source of protein, a good source of essential vitamins and minerals, and a component of many food products. The fatty acid composition of peanuts has become increasingly important with the realization that oleic acid content significantly affects the development of rancidity. And oil content of peanuts significantly affects flavor and shelf-life. Early generation screening of breeding lines for high oleic acid content greatly increases the efficiency of developing new peanut varieties. The objective of this study was to compare the accuracy of methods used to classify individual peanut seed as high oleic or not high oleic. Three hundred and seventy-four (374) seeds, spanning twenty-three (23) genotypes varying in oil composition (i.e. high oleic (H) or normal/not high oleic (NH) inclusive of all four peanut market-types (runner, Spanish, Valencia and Virginia), were individually tested ...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Evaluation of the Safety and Efficacy of Continuous Use of a Home-Use High-Frequency Facial Treatment Appliance

At present, many home-use beauty devices are available in the market. In particular, many products developed for facial treatment use light, e.g., a flash lamp or a light-emitting diode (LED). In this study, the safety of 4 weeks’ continuous use of NEWA TM , a high-frequency facial treatment appliance, every alternate day at home was verified, and its efficacy was evaluated in Japanese individuals with healthy skin aged 30 years or older who complained of sagging of the facial skin.  Transepidermal water loss (TEWL), melanin levels, erythema levels, sebum secretion levels, skin color changes and wrinkle improvement in the facial skin were measured before the appliance began to be used (study baseline), at 2 and 4 weeks after it had begun to be used, and at 2 weeks after completion of the 4-week treatment period (6 weeks from the study baseline). In addition, data obtained by subjective evaluation by the subjects themselves on a visual analog scale (VAS) were also analyzed. Fur...
