Speed of exchange is important in communication using mobile phones. This study analyzes responses to a questionnaire survey of Japanese university students about replies to mobile text messages. Respondents were asked to indicate situations where a quick reply was desired and situations where a slow reply was acceptable. Free responses were classified broadly into seven groups such as "attributes of the other party," "one's own emotional state," "one's own situation," and "situation of the other party." Additionally, gender differences were seen in these free responses, with men more often referring to the attributes of the other party and their own situation and women more often referring to the content of the text messages. The results of the questions asking respondents to rank emotions by desired speed of response showed that there are individual differences in the relation between the type of emotion conveyed and the desired speed of reply (e.g.;a quick reply was desired when joy or apology was conveyed). These individual differences were then aggregated into three types by cluster analysis. © 2014 Elsevier Ltd. All rights reserved.

Reducing dietary salt intake remains a challenging issue in the management of chronic disease. Taste preference is suspected to be an important proxy index of daily sodium consumption. This study examined the difference in daily sodium intake according to self-reported taste preference for miso soup as representative of homemade cooking in middle-aged urban Japanese adults. Among 896 candidates randomly selected from examinees of cancer screening provided by the National Cancer Center, Japan, 143 men and women participated in this cross-sectional study. During the period from May 2007 through April 2008, participants provided a food frequency questionnaire, which included information on taste preference and dietary behaviors, a weighed food record over 4 consecutive days, a simultaneous 24-hour urine collection, and a sample of miso soup as it is usually prepared in the home. Mean 24-hour urinary sodium excretion and daily sodium intake were compared according to the self-reported taste preference for miso soup. Taste preference was significantly associated with both 24-hour urinary sodium excretion (trend P<0.01) and daily sodium intake (trend P=0.01), with a corresponding regression coefficient per 1 rank preference increment of 403 mg and 315 mg/day, respectively. The observed association between preference and urinary excretion was attenuated by further adjustment for discretionary salt-related behaviors. These findings suggest that self-reported taste preference for homemade cooking is a defining feature of daily sodium intake through discretionary salt-related dietary behaviors. A reduction in daily sodium consumption per 1 rank light preference was estimated to equate to approximately 1 g salt/day. © 2014 Academy of Nutrition and Dietetics.

In the field of environmental psychology, there is rapidly growing interest in the concept of connectivity with nature, describing an individual's sense of being connected with nature. The author developed a new scale for assessing feelings toward nature, including connectedness. Confirmatory factor analysis indicated a five-factor model consisting of restorativeness, oneness, mystery, care, and aversion. Then, the relationships among availability of nature in respondents' neighborhood, age, and each subscale score of the Feelings toward Nature Scale were analyzed using structural equation modeling. The availability of nature in neighborhoods was assessed using a geographic information system and respondents' subjective evaluations. Results indicate that overall connectedness to nature is weaker as availability of nature decreases, as assessed by subjective evaluation. Results also suggest that aversion toward nature in younger people is relatively stronger than in older generations.

Phyllosomas (planktonic larvae) of slipper lobsters cling onto and feed on jellyfish under both natural and laboratory conditions. Phyllosomas of Ibacus novemdentatus are capable of feeding on various jellyfish species including venomous stingers; however, the range of jellyfish species capable of supporting the growth and survival of phyllosomas is unknown. Seventeen (12 for the first and five for the second trials) and 18 (13 for the first and five for the second trials) phyllosomas were fed exclusively on the jellyfish Aurelia aurita and Chrysaora pacifica, respectively. Aurelia aurita-fed phyllosomas metamorphosed into the nisto stage (postbenthic larvae) ∼54 days after hatching, whereas C. pacifica-fed phyllosomas did not. Major nutritional compositions such as amino acids, fatty acids and minerals were compared between the two jellyfish species. The proportion of each major nutritional component was not significantly different between the two jellyfish species, suggesting that C. pacifica was not nutritionally inferior to A. aurita. Therefore, the observation that the C. pacifica-fed phyllosomas did not metamorphose into the nisto stage was not because of major nutritional compositions but due to other factors such as the lack or excess of other minor nutrients, or the species-specific texture of the jellyfish. © 2015 John Wiley & Sons Ltd.

Pacific oysters were harvested from November to March at Miyazaki and Miyagi in Japan. From biometric analysis, the condition indices (CICG; high CICG indicates large oyster meat) of oysters were high in February and March at Miyazaki whereas CICG at Miyagi showed high values in December and February. Lipid content in oysters at Miyagi harvested in February was the highest. Glycogen content was high in oysters harvested in February from both cultivation areas. In November, the calcium content in oysters harvested at Miyazaki was the highest. Taurine was the predominant free amino acid in oysters, at concentrations of 2180-3230 mg/100 g dry sample. Glutamate was the predominant component of total amino acid in oysters, at concentrations of 4530-6000 mg/100 g. The percentage of eicosapentaenoic acid (EPA) in total lipid of oysters did not show significant differences between harvesting months. Based on all analyses, oysters from Miyazaki showed good quality in March with high CICG, glycogen, and lipid contents, whereas oysters from Miyagi showed good quality in February. These analysis data including not only condition indices but also biochemical composition might be useful parameters allowing establishment of evaluation criteria. © 2011 The Japanese Society of Fisheries Science.
