Yetenek Hiyerarşisi: Üstün Yetenek Türlerinin Toplumsal Değerleri Üzerine Bir Araştırma (Talent Hierarchy: A Research Study on the Social Value of Talent Types)

Purpose and significance: The purpose of this research study was to investigate social values of talent types that were identified based on the psychosocial classification of talents proposed by Tannenbaum (1983). According to this model talents can be classified based on their social values into scarcity talents that preserve and prolong life, surplus talents that elevate sensibilities and sensivities, quota talents that provide goods and services and anomalous talents that provide enjoyment. The societal value of a talent contributes to the degree to which parents in particular and governments and educational institutions in general make investment in the nurturance of this talent. Method: A likert-type questionnaire consisting of 60 different types of talents was developed based on the Tannenbaum Model. Talents were identified through reviewing inventions books, expert opinions and the Guinness Records. The questionnaire included 15 talent types for each class of the Tannenbaum Model. Each talent type was scored from 1 to 4 (1 = above-average; 2 = high; 3 = very high; 4= extraordinarily high) based on its value as perceived by the participants. The questionnaire was administered to 601 people (female = %36.4; male = 63.6) in a major city in the middle part of Turkey. Two criteria were used for participation in the study: Volunteer participation and being over 18-years old. Their age ranged from 18 to 72 with a mean of 27.14 and standard deviation of 10.83. Their educational status also ranged from elementary school and high school graduates (%38) to university students and university graduates (%62). The scale was given to all participants face to face, taking 15 minutes for each participant. Paired-samples t-test was used to compare mean scores of the talent categories and independent-samples t-test was used to test gender differences. Results: Results showed that scarcity talents were rated as the highest (M = 3.06; SD = .57) followed by surplus talents (M = 2.69; SD = .61), quota talents (M= 1.96; SD= .62), and anomalous talents (M= 1.90; SD= .59). The differences between the means were found to be significant (p< .00 for all). The highest rating was given to the item “the person who leads the independence war of a country” (M = 3.49; SD = .77); followed by “the person who discovers electricity” and “the person who finds the cure for cancer.” The lowest rating was given to the item the person who makes the best saddles” (M = 1.68; SD = .97). Furthermore, female participants scored the scarcity talents and the surplus talents higher than male participants did. The differences were statistically significant (p< .00). Effect sizes were found to be low to medium (d = .39 and .48 respectively). Similar gender differences were not observed in quota and anomalous talents. Discussion and Conclusions: Research findings imply a hierarchy among talent types with scarcity talents being at the top followed by surplus talents, quota talents and then anomalous talents. Findings also show that talent types related to scientific explorations and inventions, such as “the founder of cure for cancer” and “inventor of genetic cloning,” are attached much more societal value than all other types of talents. What is more interesting is the finding that the item “the leader of the independence war of a country” in the scarcity talents was rated by the participants as the highest talent among sixty talent types, and the item “a commander who successfully overcomes terrorism” was rated the highest among the quota talents. These findings apparently show that talents have societal roots, because Turkey had an independence war in the last century and has experienced terrorism for the last thirty years. Why females attach more value to scarcity and surplus talents than males also is an intriguing finding that needs further explorations

Antimikrobiyal Medikal Tekstil Ürünleri için Oleuropein Uygulaması

The olive plant has been an important source of nutrition and medicine of the Mediterranean. In this study it is aimed to design a textile product conserve oleuropein compound as a medical textile. Oleuropein was used in different concentrations with different cross-linker and applied to cotton fabric by pad-drycure method. FTIR-ATR and SEM were used to examine the presence of the oleuropein on the cotton fabrics. The oleuropein applied cotton fabrics antimicrobial activity test was performed against both gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacteria. The durability of the antimicrobial activity of cotton fabrics was tested after 10 washing cycles at 40 °C for 30 min. Tensile strength tests of the fabrics were performed to evaluate the effect of oleuropein solution pH value changes. Air permeability and whiteness values of fabrics were performed on the fabrics before and after the treatment with oleuropei

Electrostatic self-assembly dyeing of cotton fabrics

A new approach to the dyeing of cotton fabrics using an electrostatic self-assembly method was evaluated. Cotton fabrics were pretreated with 2,3-epoxypropyltrimethylammonuium chloride and cationic charges were produced on the fabric surfaces. For the dyeing of cotton fabric, reactive and acid dyes were used. Oppositely charged anionic reactive/acid dyes and cationic poly(diallyldimethylammonium chloride) were alternately deposited on the surface of cationised cotton fabrics. Ten multilayer films of dye/poly(diallyldimethylammonium chloride) were deposited on the cotton fabric surfaces using a padder. The build-up of the multilayer films and the level of colour strength (K/S) achieved are discussed. Samples of cotton fabrics were also dyed with the same dyes, but using the exhaust method, and both types of dyed samples were compared. The washing, rubbing and light fastness properties were evaluated for the dyed fabrics

Probing the electronic, elastic, mechanical and anisotropic features of ZrTiX

Zr-Ti-X ternary alloys are striking materials of the latest technology because of their excellent and desired mechanical aspects. Therefore, electronic, elastic, mechanical and anisotropic properties of ZrTiX4 (X = Cr, Mo, W) alloys were probed in this work for the first time via density functional theory (DFT) calculations. The computed electronic band structures disclose the metallic nature of all alloys. Further, the calculated elastic stiffness constants and linking mechanical data of all alloys demonstrate mechanical stability. All surveyed alloys display ductile mechanical character where ZrTiCr4 and ZrTiMo4 alloys are found to be more ductile than ZrTiW4. On the other hand, ZrTiW4 was determined to be approximately two times harder than the ZrTiCr4 and ZrTiMo4 alloys with a Vickers Hardness value of 8.47 GPa. Both numerical and three-dimensional (3D) analyses reveal the presence of elastic anisotropy in ZrTiX4 (X = Cr, Mo, W) alloys
