EMOTIONAL INTELLIGENCE OF LEADERS IN HIGHER EDUCATION AND ITS IMPACT ON EMPLOYEES

The purpose of this quantitative research study was to further understand the relationship between the emotional intelligence of faculty who have moved up into administrative positions and nonfaculty leaders within university academic affairs. Higher education institutions have a history of high employee turnover. There is a lack in the hiring process within higher education, and the lack of a hiring process causes difficulties when leaders go from faculty or staff roles to administrative and supervisory roles with little training on managing their emotions and employees’ emotions, hindering leaders from thriving in their leadership positions. The sampling was leaders from traditional 4-year state institutions in Texas. The Mayer-Salovey-Caruso Emotional Intelligence Tests (MSCEIT™) were used to measure the emotional intelligence of leaders. A total of 489 participants were contacted via email, and 124 attempts were made to complete the survey; 54 surveys were fully completed and used for this study. The statistical analyses used included descriptive statistics, correlation coefficient, analysis of variance (ANOVA), t test. No statistically significant differences or relationships among variables were found, and the descriptive statistics found the mean score for overall emotional intelligence score was 91.5, which was slightly over the standard score. The consider developing level of the MSCEIT™ has a standard score range ending at 89. The raw data showed that 20 of the 54 participants had levels of emotional intelligence below the competent level. Therefore, these leaders should consider enhancing these skills as interacting and leading employees is essential to being a leader

Testing Models of Consumer Search using Data on Web Browsing and Purchasing Behavior

Using a large data set on web browsing and purchasing behavior we test to what extent consumers are searching in accordance to various classical search models. We nd that the benchmark model of sequential search with a known distributions of prices can be rejected based on the recall patterns we observe in the data. Moreover, we show that even if consumers are initially unaware of the price distribution and have to learn the price distribution, observed search behavior for given consumers over time is more consistent with non-sequential search than sequential search with learning. Our ndings suggest non-sequential search provides a more accurate description of observed consumer search behavior. We then utilize the non-sequential search model to estimate the price elasticities and markups of online book retailers.consumer search, electronic commerce, consumer behavior

Effect of 6-thioguanine on the stability of duplex DNA

The incorporation of 6-thioguanine (S6G) into DNA is a prerequisite for its cytotoxic action, but duplex structure is not significantly perturbed by the presence of the lesion [J. Bohon and C. R. de los Santos (2003) Nucleic Acids Res., 31, 1331–1338]. It is therefore possible that the mechanism of cytotoxicity relies on a loss of stability rather than a pathway involving direct structural recognition. The research described here focuses on the changes in thermodynamic properties of duplex DNA owing to the introduction of S6G as well as the kinetic properties of base pairs involving S6G. Replacement of a guanine in a G•C pair by S6G results in ∼1 kcal/mol less favorable Gibbs free energy of duplex formation at 37°C. S6G•T and G•T mismatch-containing duplexes have almost identical Gibbs free energy at 37°C, with values ∼3 kcal/mol less favorable than that of the control. Base pair stability is affected by S6G. The lifetime of the normal G•C base pair is ∼125 ms, whereas that of the G•T mismatch is below the detection limit. The lifetimes of S6G•C and S6G•T pairs are ∼7 and 2 ms, respectively, demonstrating that, although S6G significantly decreases the stability of the pairing with cytosine, it slightly increases that of a mismatch

Diffusion-limited deposition of dipolar particles

Deposits of dipolar particles are investigated by means of extensive Monte Carlo simulations. We found that the effect of the interactions is described by an initial, non-universal, scaling regime characterized by orientationally ordered deposits. In the dipolar regime, the order and geometry of the clusters depend on the strength of the interactions and the magnetic properties are tunable by controlling the growth conditions. At later stages, the growth is dominated by thermal effects and the diffusion-limited universal regime obtains, at finite temperatures. At low temperatures the crossover size increases exponentially as T decreases and at T=0 only the dipolar regime is observed.Comment: 5 pages, 4 figure

DETECCIÓN DE BEGOMOVIRUS EN PLANTAS DE Jatropha curcas L., EN CHIAPAS, MÉXICO

The Mexican pine (Jatropha curcas L.) is the most promising non-edible plant for the biofuel industry in the world. The state of Chiapas, south of Mexico, inhibits high diversity of genotypes, with differences in agronomic traits such as greater number of floral events, high production and oil quality of its seeds. Despite such agronomic traits, it is susceptible to Jatropha mosaic disease (JMD), caused by begomovirus (Geminiviridae). In this study, we reported the presence of begomovirus related to Jatropha mosaic disease by visual detection in five populations of Tapachula, Chiapas, Mexico. The observed symptoms were mosaics, curls and leaf malformations. The presence of begomoviruses associated with JMD was confirmed by PCR obtaining 88% of positive samples to the infection and only 12% were healthy plants. In addition, the molecular detection allowed to observe that 16 asymptomatic samples were positive to the infection. The dependence between the symptoms of JMD and the presence of begomovirus was significant. This work represents the first report of begomovirus infecting Jatropha curcas L. plants in southern Mexico.El piñon mexicano (Jatropha curcas L.) es la planta no comestible más prometedora para la industria de biocombustibles en el mundo. El estado de Chiapas, al sur de México, presenta alta diversidad de genotipos, con diferencias en rasgos agronómicos como mayor número de eventos florales, alta producción y calidad del aceite de sus semillas. A pesar de dichos rasgos agronómicos, es susceptible a la enfermedad del mosaico de Jatropha (EMJ), causada por begomovirus (Geminiviridae). Mediante detección visual, en este estudio se caracterizó la sintomatología reportada para la enfermedad del mosaico de Jatropha en cinco poblaciones de Tapachula, Chiapas, México; los síntomas observados fueron mosaicos, enrollamientos y malformaciones foliares. Se confirmó la presencia de begomovirus asociados a la EMJ, mediante PCR obteniendo 88% de muestras positivas a la infección y solo el 12% fueron plantas sanas. En adición, la detección molecular permitió observar que 16 muestras asintomáticas fueron positivas a la infección. La dependencia entre los síntomas de la EMJ y la presencia de begomovirus fue significativa. Este trabajo representa el primer reporte de begomovirus infectando plantas de Jatropha curcas L. en el sur de México

Incorporation of 3-Aminobenzanthrone into 2′-Deoxyoligonucleotides and Its Impact on Duplex Stability

3-Nitrobenzanthrone (3NBA), an environmental pollutant and potent mutagen, causes DNA damage via the reaction of its metabolically activated form with the exocyclic amino groups of purines and the C-8 position of guanine. The present work describes a synthetic approach to the preparation of oligomeric 2′-deoxyribonucleotides containing a 2-(2′-deoxyguanosin-N2-yl)-3-aminobenzanthrone moiety, one of the major DNA adducts found in tissues of living organisms exposed to 3NBA. The NMR spectra indicate that the damaged oligodeoxyribonucleotide is capable of forming a regular double helical structure with the polyaromatic moiety assuming a single conformation at room temperature; the spectra suggest that the 3ABA moiety resides in the duplex minor groove pointing toward the 5′-end of the modified strand. Thermodynamic studies show that the dG(N2)-3ABA lesion has a stabilizing effect on the damaged duplex, a fact that correlates well with the long persistence of this damage in living organisms
