Role of 1-MCP in regulating 'Kensington Pride' mango fruit softening and ripening

Ripening of mango fruit is characterized by softening of flesh which limits its shelf life. 1-MCP is nontoxic gas that delays fruit softening and improves quality of several fruit. Therefore, the role of 1-MCP in regulating fruit softening and quality of ‘Kensington Pride’ mango was investigated. Physiological mature fruits treated with 1-MCP (1 mL L-1), ethylene (10 mL L-1) or 1-MCP + ethylene for 12 h at ambient condition (20 ± 1 C). Untreated (control) as well as treated fruits were allowed to ripe at ambient temperature (20 ± 1 C) for 10 days. Ethylene production, respiration rate and other fruit ripening parameters were determined periodically. Climacteric peaks of ethylene production and respiration rate were significantly supressed by 1-MCP application as compared to ethylene-treated and control fruit. Exogenous application of ethylene accelerated the development of fruit colour, fruit softening with increased activities of exo-PG, endo-PG and EGase enzymes in the pulp tissues. Whereas, activities of fruit softening enzymes were significantly delayed and/or suppressed in 1-MCP-treated fruit. 1-MCP-treated fruit showed improved rheological properties (i.e., firmness, springiness and stiffness), decreased level of citric acid, malic acid, succinic acid, total organic acids, total sugars and sucrose than other treatments. 1-MCP inhibited the activities of fruit softening enzymes which consequently delayed the ripening and ripening related changes in ‘Kensington Pride’ mango

Cross-cultural investigation of the link between identity processing styles and the actual work of identity in the career domain

The current study investigated and compared the associations between identity processing styles and the actual work of identity formation in the career domain in two national contexts, the US and Turkey. Identity styles represent individuals' orientations to identity work, and were measured by the Identity Processing Styles Q-Sort (IPSQ). The actual work of identity indicates engagement in exploration and commitment activities at multiple levels; and was measured by an adapted version of the Dimensions of Identity Development Scale (DIDS). In the current study, the actual work of identity was examined in the career domain only. The effects of gender and work status while in school on identity formation process in two national contexts also were examined. Results of the current study showed that the associations between identity processing styles and the actual work of identity are consistent across the two contexts, except that there is a stronger relation between informational style and identity work in Turkey; the impact of gender and work status on the actual work of identity also differed across contexts. The similarities and differences across the American and Turkish samples are discussed within the framework of broader contextual differences

Impact of cognitive style on group decision and negotiation

Numerous studies on group decision and negotiation have focused on the influence of the cognitive style of decision makers. Using number of instruments such as Kirton Adaption Innovation (KAI), Cognitive Style Index (CSI), Kolb Learning Style Inventory (KLS), Belbin team role self‐perception inventory, or the well-known Myers-Briggs Type Indicator (MBTI), studies explore relationships between different dimensions of the personality traits of the individuals and the performance of group decisions. The results are very heterogeneous and sometimes contradictory, depending in particular on the decision contexts explored (strategic decision or not, etc.) and the type of measurement and proxy used to identify the cognitive style. When cognitive diversity is the variable used in these researches, it is no longer the influence of an individual cognitive style on the decision that becomes the object of study but the fact that several styles are represented among the members of a group of decision makers. Looking for an integrative group of decision makers, as it is finally proposed in this chapter through a cognitive mapping-based method, is then a way to increase group decision performance

Decision-Making Styles, Negative Affectivity, and Cognitive Distortions in Adolescent Gambling

Evidences from the extant literature suggest that problem gamblers show higher cognitive distortions and reported experiencing higher levels of negative affective states than recreational gamblers. Furthermore, several studies reported that the more the gambling severity, the poorer the performance in behavioral tasks assessing affective decision-making. Although gambling research on decision-making has mostly focused on the functional or dysfunctional outcomes of the decisional process, no study examined the role of decision-making styles in gambling disorder. This study aimed to first investigate the interplay among negative affectivity, cognitive distortions, and decision-making styles in adolescent problem gambling. Four hundred and twenty-five adolescents, aged between 14 and 19 years, completed the South Oaks Gambling Screen Revised for Adolescents to assess problem gambling, the Depression Anxiety and Stress Scales-21 to measure negative affective states, and the Gambling Related Cognitions Scale as a measure of cognitive distortions about gambling, and the General Decision-Making Style tapping habitual patterns which individuals use in decision-making. Data were submitted to correlational analysis, univariate and mixed-model ANOVAs, and hierarchical regression analysis. Regression analysis indicated that, along with gender, interpretative bias and inability to stop gambling, depression, and spontaneous decision-making style significantly predicted gambling severity. These results extend further previous studies on the role of misconceptions about gambling, and negative affective states in adolescent gambling, and, interestingly, first demonstrate that also maladaptive decision-making styles may represent a risk factor for gambling disorder
