Algal enrichment process for newly formed sea ice in the Dalton polynya off East Antarctica during the late summer–early autumn
Newly formed sea ice can incorporate considerable amounts of organic matter including phytoplankton during its freezing and growth. This initial incorporation influences the standing stocks of ice algae, a fundamental component of high-latitude marine ecosystems. Physical incorporation via the accretion of frazil ice, instead of congelation growth, is considered to incorporate particles efficiently. However, for thin ice (<0.20 m thickness), info…
Characteristics of late summer Arctic brash sea ice and its melting effect on the surface-water biogeochemistry of the Chukchi Shelf and Canada Basin
To understand the impact of the melting of late summer Arctic brash ice on the surface waters of the Chukchi Sea, we collected sea-ice samples during 2021. Floating sea ice was collected by a wire mesh pallet cage from the side of the R/V Mirai. We measured physical and biogeochemical parameters such as salinity, oxygen stable isotopic ratios, turbidity, and concentrations of chlorophyll-a and nutrients. The samples of brash ice were multiyear ic…
Association between occupation type and development of type 2 diabetes
Background Due to a lack of investigation on the association between the type of occupation and the development of type 2 diabetes among Japanese individuals, we aimed to assess this association in 98,935 Japanese individuals. Methods This long-term retrospective cohort study included participants selected from medical health checkup programs conducted at the Panasonic Corporation, Osaka, Japan, from 2008 to 2018. Cox regression analyses were use…
The Risk Factors for Development of Type 2 Diabetes
(1) Background: As no study has evaluated the risk factors contributing to the development of type 2 diabetes according to body weight mass (BMI) categories in a large cohort and over a long period in a Japanese population, we aimed to assess them in 46,001 Japanese individuals; (2) Methods: This long-term retrospective cohort study included individuals who participated in a medical health checkup program at Panasonic Corporation from 2008 to 201…
Control of monkey's spaced responding by sample durations
Monkeys were exposed to a modified schedule of differential reinforcement of long latency in which a sample duration was presented prior to each response. Monkeys received food following response latencies longer than the sample duration. Spaced responding was well described by a power function. A differentiation of spaced responding for two different sample durations was established by setting upper limits to the reinforced latency and introduci…
Temporal Discrimination in Japanese Monkeys
Temporal discrimination in Japanese monkeys was examined adopting a psychophysical method, originally developed in the study of pigeons, and modified in the present study by adding a sample duration prior to each trial in order to make the procedure close to the method of reproduction in human psychophysics. When only one sample duration was employed within a session, the subjects' performance was independent of the sample duration and was based …
A Comparison of Two Different Operanda for Shaping and Maintaining Avoidance Behavior in the Pigeon
The effectiveness of a treadle and a key as operanda in shaping and maintaining avoidance responding under a free operant situation was examined in pigeons. Pigeons were trained to press a treadle, to press a key, or to do both according to the prescribed order. The within-subjects comparison showed that the treadle pressing response was more easily shaped and maintained than the key pressing response. Also the key pressing response observed in t…
