    Forage production in the Texas High Plains, a semi-arid region, is critical to sustain the local cattle industry. However, the main source of water for irrigation is the highly depleted Ogallala Aquifer, making forage crop water productivity (CWP) of high importance. In this one-year study, three types of forages were cultivated under deficit irrigation treatments of 80% and 50% of full crop water use. The forages were: a non-brown midrib forage sorghum; a legume, sunn hemp; and a sorghum/sunn hemp mix. The experiment was conducted in Bushland, Texas in 2019. Treatment plots were arranged in a split plot design with four replications under a 6-span variable rate irrigation center pivot sprinkler. Above ground biomass samples were taken by hand from a 1 m2 quadrat in each of the 24 plots on Jul 23, Aug 6 for forage analysis, and on Aug 19 to assess biomass yield and CWP. Crude protein was significantly higher at the first and second cuttings in the sunn hemp monocrop, but not significantly different between irrigation levels. The final biomass yields and CWP were similar between the sorghum (23.6 Mg ha-1) and sorghum/sunn hemp (25.1 Mg ha-1) forages, irrespective of irrigation level. The sunn hemp monocrop produced significantly lower biomass (9.75 Mg ha-1), which reduced CWP

    All internet connected organizations are becoming increasingly vulnerable to cyberattacks due to information security policy noncompliance of personnel. The problem is important to information technology (IT) firms, organizations with IT integration, and any consumer who has shared personal information online, because noncompliance is the single greatest threat to cybersecurity, which leads to expensive breaches that put private information in danger. Grounded in the protection motivation theory, the purpose of this quantitative study was to use multiple regression analysis to examine the relationship between perceived importance, organizational compliance, management involvement, seeking guidance, and rate of cybersecurity attack. The research question for this study was focused on the relationship between perceived importance of cybersecurity, senior management involvement, use of organizational ISPC, seeking of information or guidance on cybersecurity, and organizational security breach incidence. Data was collected from the United Kingdom’s 2021 Cyber Security Breaches Survey. Multiple linear regression analysis yielded that the four independent variables were not predictive of instances of cybersecurity breach or attack. The implications for positive social change include the potential to actively promote and publicly address cybersecurity as personal privacy increasing becomes a matter of public safety. One key recommendation is for IT leaders to pursue methodologically rigorous and uniform operationalization throughout IT research and practice, including the pursuit of replicable data of detailed resolution. The results of this study may potentially be used to reduce the risks for cybersecurity breaches, which ultimately contributes to social change by furthering the right of privacy and the protection of personal information

    Se asume que una estrategia adecuada impactará positivamente las ganancias de la empresa y le llevará a expandirse. Recientes descubrimientos sugieren que sólo con la revisión y adecuación de los elementos más relevantes del plan estratégico es posible llevar los resultados económicos de la empresa a un punto óptimo. La metodología PIMS (que se traduce como Impacto de la Estrategia de Marketing sobre las Ganancias) constituye un modelo para lograrlo, sin embargo, subsisten problemas fundamentales en el mismo modelo que lo limitan. Así, en el presente trabajo se hace un estudio exploratorio y se muestra la evolución de la metodología PIMS lo cual permite desvelar los retos y el posible rumbo del tema. La definición de la estrategia, el diseño de la encuesta tipo PIMS, los problemas de multicolinearidad y el efecto de la participación de mercado se plantean como los más relevantes. Los resultados muestran la necesidad de definir con precisión la estrategia asumida por la empresa, el rediseño de la encuesta PIMS cuando se aplique a mercados incompletos y finalmente, se advierte un avance en el estudio econométrico sobre la metodología PIMS con énfasis en la variable Calidad Relativa del Producto para resolver el viejo dilema del efecto de la participación de mercado

    Nutritional standards through Integrated Differential Diagnosis (IDD) in pomegranate (Punica granatum L.)

    The foliar analysis is a useful tool to detect the nutritional status of plants, predict future problems in the reproductive cycles of fruit production and implement preventive and corrective measures to achieve a mineral balance in fruit trees, obtaining higher productivity. There is little information available on nutrient sufficiency ranges in pomegranate leaf and the literature reported differs due to diverse cultivation practices, cultivars, and agroecological conditions. Therefore, the objective of this work was to determine the mineral content of ‘Wonderful’ pomegranate leaves for each the nutritional elements and the cation balance, and to establish the nutritional standards using Integrated Differential Diagnosis (IDD). The mineral content of the pomegranate leaves was determined and based on the results, nutritional standards for macro elements, cation balance and microelements were generated through the IDD, which evaluate whether there are mineral and/or physiological imbalances. The macro elements in the cultivation of the pomegranate were the following: NO3 3747.5 µg g-1, Total Nitrogen 1.35%, P 0.14%, K 0.88%, Ca 1.65%, Mg 0.19%, Na 0.006%. For the cation balance, the optimal values ​​were: (Ca+Mg)/K 4.48 mEq 100 g-1, Ca/(K+Mg) 2.13 mEq 100 g-1, Mg/(K+Ca) 0.16 mEq 100 g-1, Ca/Mg 5.06 mEq 100 g-1, K/Mg 1.36 mEq 100 g-1. Finally, the optimal values ​​for the microelements were: Fe 59.5 µg g-1, Mn 31.4 µg g-1, Zn 6.3 µg g-1, Cu 6.1 µg g-1. The values ​​obtained for the micro and macro elements were like those reported. In the case of cation balance and foliar nitrate content, they have not been previously reported. The IDD is a promising and effective auxiliary tool to characterize the nutritional status of pomegranate trees and, in turn, an alternative to conventional methods of nutritional diagnosis with the advantage of establishing a nutritional deficiency (soil-plant relationship) or a physiological imbalance (relation plant - climate) for this crop

    The consumption of fruits rich in antioxidants has increased in recent years, a clear example of this is the pomegranate (Punica granatum L.). The cultivation of the pomegranate shows great expectations due to its profitability and its adaptability to development in arid zones. In this research, ‘Wonderful’ pomegranate fruits from Coyame Chihuahua, México were used. Quality parameters and bioactive compounds were evaluated to characterize the pomegranate produced in the state of Chihuahua, six different lots from local producers were used. The results showed significance between the different treatments, lot 5 (L5) presented the best quality characteristics such as: weight, diameter, lower percentage of shell and cartilage, as well as one of the highest percentages of arils, in addition, it had a high Total Soluble Solids (TSS) content, a high Titratable Acidity (TA) and a low sugar-acidity ratio, however, lot 3 (L3) showed the highest antioxidant capacity. In general, the qualities and attributes of the Chihuahua pomegranates, obtained higher values ​​in most of the evaluated variables in comparison with other reported results. On the other hand, as a result of this research, the implementation of the color index in the peel is proposed as a tool for the prediction of the maturity index of the pomegranate. This study contributes to the producers of this fruit tree because there is little information on the production and characterization of the pomegranate

    The objective of this work was to analyze a mediation model concerning the perception ofan empowering climate generated by a coach and enjoyment through the autonomous motivation ofathletes. The sample consisted of 71 elite male volleyball players from six countries. The age rangewas 14 to 18 years (M=16.5, SD=0.96). The relationships between the perception of an empoweringclimate, autonomous motivation, and enjoyment were positive and significant. The mediation modelshowed that autonomous motivation acts as a mediator in the relationship between the perception ofan empowering climate generated by the coach and the enjoyment reported by the athletes
