The best leadership practices of principals in high performing and high poverty schools in Ohio
The current accountability movement faced by schools throughout the country has prompted educators to close the achievement gap or else face a barrage of federal, state, and public backlash. Schools which have met overall standards will not be considered successful unless they have done something to close the achievement gap. The gaps generally occur among the economically disadvantaged students, minority groups, and those with learning disabilities. The subgroup of particular interest for this research is low socio-economic status students (SES). Principals are the instructional leaders of their buildings. This research focuses on how school leaders are helping disadvantaged students.;To determine what leaders of high performing and high poverty schools are doing to close the achievement gap, a mixed methodology study was completed. Principals in Ohio Schools of Promise (high poverty schools which achieve at high levels on the Ohio Achievement Tests) were asked to complete the Kouzes and Posner Leadership Profile Inventory (LPI) self-survey. A comparison of urban and rural principals was conducted using multiple independent samples t-tests. The results of the survey were also the basis for identifying thirty teachers to interview. The interviews were designed to identify the best practices of principals in these high performing and high poverty schools. A regression analysis was performed to examine possible links between any of several demographic variables and LPI mean scores.;Results of the statistical tests indicated no significant differences in how urban and rural principals in Schools of Promise viewed their strengths and weaknesses as leaders. The regression analysis suggested there a statistically significant relationship between the composite LPI mean scores of principals and both administrative years of experience and student teacher ratio at the .05 level. Emergent themes resulting from the teacher surveys revealed best practices in five leadership areas: modeling the way, inspiring a shared vision, challenging the process, encouraging the heart, and enabling others to act.;The achievement gap between students from low SES backgrounds and their more affluent counterparts has been closed in many schools. The results of this study demonstrate that there are specific strategies leaders can take to help close the gap. The study suggests important steps which can be taken by educators at the building and district levels, as well as the graduate level, to help all students achieve at high levels

Resource Analysis in Logistics Processes Planning
Resursi unutar logističkog sustava su bitan čimbenik koji utječe na poslovanje samog sustava. Višak ili manjak resursa stvara troškove u poslovanju, te se time teži optimizaciji resursa. Optimizacijom resursa moguće je postići poboljšanje odvijanja samih procesa unutar sustava, povećati učinkovitost rada, a samim time i smanjiti troškove poslovanja. Izračunavanjem radne učinkovitosti pojedinog resursa moguće je prikazati koliko je neki resurs efikasan u obavljanju svoje djelatnosti, te postaviti norme za standardizaciju obavljanja iste te djelatnosti u doglednom periodu. Time se dolazi do saznanja da je potrebno pomno planiranje logističkih procesa. Ovim završnim radom prikazat će se organizacija resursa u planiranju logističkih procesa skladišta, izračuni radne učinkovitosti pojedinih resursa, skladišne operacije i primjena mjerenja radne učinkovitosti kod skladišnih operacija.Resources within the logistic process are important part which are directly related with business system. The main reason for costs in business are surplus or deficit, to avoid that we need to optimize our resources. If we manage to do that with optimization it will bring us better reeling in system, increase working efficiency and reduce costs. In case that is possible to calculate working efficiency of each resources than it’s also possible to show which resource if efficient and set norms for standardization in performing activities in specified time. All of the above is important for planning logistics process carefully. This final work will show you organization of resources in planning logistics process in warehouses, calculations for work efficiency, warehouses operation and using measures of work efficiency in warehouse operation

Congestion avoidance in city traffic
The number of vehicles on the road (worldwide) is constantly increasing, causing traffic jams and congestion especially in city traffic. Anticipatory vehicle routing techniques have thus far been applied to fairly small networked traffic scenarios and uniform traffic. We note here a number of limitations of these techniques and present a routing strategy on the assumption of a city map that has a large number of nodes and connectivity and where the vehicles possess highly varying speed capabilities. A scenario of operation with such characteristics has not previously been sufficiently studied in the literature. Frequent short-term planning is preferred as compared with infrequent planning of the complete map. Experimental results show an efficiency boost when single-lane overtaking is allowed, traffic signals are accounted for and every vehicle prefers to avoid high traffic density on a road by taking an alternative route. Comparisons with optimistic routing, pessimistic routing and time message channel routing are given Publisher statement: This is the peer reviewed version of the following article: Kala, Rahul and Warwick, K.

The role of mtDNA damage in mitochondrial dysfunction
Mammalian mitochondria have a 16.5 kb genome encoding for 13 polypeptides, 2 rRNAs, and 22 tRNAs essential for mitochondrial function. Mutations and deletions in mitochondrial DNA (mtDNA) are implicated in some hereditary diseases as well as aging, cancer and neurodegeneration. Here, we examine the role of DNA ligase in mtDNA maintenance, and the role of mtDNA damage inflicted by hydrogen peroxide (H2O2) or methyl methanesulfonate (MMS) in mitochondrial dysfunction. We establish that mitochondrial DNA ligase activity is essential for survival, persistent mtDNA damage is not sufficient to induce rapid mtDNA loss and mitochondrial dysfunction. We removed and replaced the normal mitochondrial DNA ligase III with different forms of mitochondrially-targeted DNA ligase, and found that mitochondrial DNA ligase activity is necessary for cellular survival and that any type of DNA ligase activity in the mitochondria is sufficient to maintain mtDNA integrity and copy number. To study the relationship between mtDNA integrity and mitochondrial function, we treated cells with H2O2 or with the alkylating agent MMS, both of which resulted in persistent mtDNA lesions. However, only the H2O2-treated cells showed mtDNA loss and mitochondrial dysfunction by 8 hours post-treatment, indicating that persistent mtDNA damage does not necessarily cause a rapid loss of mtDNA or mitochondrial function. These data suggest that oxidants are more efficient than alkylating agents at driving mtDNA loss and mitochondrial dysfunction.
We then addressed the cause of H2O2-induced loss of mtDNA 8 hours following treatment. We hypothesized that this loss of mtDNA is dependent upon mitochondrial fission and mitophagy. In order to test this hypothesis, we treated cells with the fission inhibitor mdivi-1. Mdivi-1 protected mtDNA against oxidative-induced mtDNA damage but not MMS-induced mtDNA damage. Because mdivi-1 is thought to act through inhibition of Drp1, we performed siRNA-mediated knockdown (KD) of Drp1 and observed that the knockdown did not recapitulate mdivi-1 treatment in protecting against H2O2-induced mtDNA damage. Furthermore, treating Drp1 KD cells with mdivi-1 still showed the protective effects of mdivi-1 on mtDNA damage. These results suggest that the mdivi-1 mediated protection of oxidant-induced mtDNA damage may be independent of its role in inhibiting mitochondrial fission
