Assessing the Groundwater Reserves of the Udaipur District, Aravalli Range, India, Using Geospatial Techniques
Population increase has placed ever-increasing demands on the available groundwater (GW) resources, particularly for intensive agricultural activities. In India, groundwater is the backbone of agriculture and drinking purposes. In the present study, an assessment of groundwater reserves was carried out in the Udaipur district, Aravalli range, India. It was observed that the principal aquifer for the availability of groundwater in the studied area is quartzite, phyllite, gneisses, schist, and dolomitic marble, which occur in unconfined to semi-confined zones. Furthermore, all primary chemical ingredients were found within the permissible limit, including granum. We also found that the average annual rainfall days in a year in the study area was 30 from 1957 to 2020, and it has been found that there are chances to receive surplus rainfall once in every five deficit rainfall years. Using integrated remote sensing, GIS, and a field-based spatial modeling approach, it was found that the dynamic GW reserves of the area are 637.42 mcm/annum, and the total groundwater draft is 639.67 mcm/annum. The deficit GW reserves are 2.25 mcm/annum from an average rainfall of 627 mm, hence the stage of groundwater development is 100.67% and categorized as over-exploited. However, as per the relationship between reserves and rainfall events, surplus reserves are available when rainfall exceeds 700 mm. We conclude that enough static GW reserves are available in the studied area to sustain the requirements of the drought period. For the long-term sustainability of groundwater use, controlling groundwater abstraction by optimizing its use, managing it properly through techniques such as sprinkler and drip irrigation, and achieving more crop-per-drop schemes, will go a long way to conserving this essential reserve, and create maximum groundwater recharge structures.

Performance management in the public sector
\"In times of rising expectations and decreasing resources for the public sector, performance management is high on the agenda. Increasingly, the value of the performance management systems themselves is under scrutiny, with more attention being paid to the effectiveness of performance management in practice. This new edition of Performance Management in the Public Sector explores performance, as well as performance measurement, and making performance information useful for management. The book includes: - situates performance in some of the current public management debates, including some emerging discussions on the new public governance and neo-Weberianism; - discusses the many definitions of performance and how it has become one of the most contested agendas of public management; - examines the use as well as the non-use of performance information; - conveys a nuanced discussion of the so-called perverse effects of using performance indicators; - discusses the technicalities of performance measurement in a five step process: prioritising measurement, indicator development, data collection, analysis and reporting; and - explores the challenges and future directions of performance management Performance Management in the Public Sector 2nd edition offers an approachable insight into a complex theme for practitioners and students alike. For scholars, the book directs attention to key research issues, most pressingly the use of performance information\"-- Provided by publisher.

Potential and Distribution of Natural Gas Hydrate Resources in the South China Sea
The amount of natural gas contained in the world’s gas hydrate accumulations is enormous, but these estimates remain highly speculative. So far, it is still challenging to locate spatial distribution of marine gas hydrate and quantitatively characterize the evaluation parameters and systematic improvement of evaluation systems. Considering the systematic review of the key accumulation factors, such as heat flow, deposition rate and total organic carbon in the typical passive continental margin, the evaluation results of global marine gas hydrate resources were analyzed based on the characteristics of gas hydrate geology, geophysics and geochemistry anomalies in the South China Sea. We analyze the problems on the evaluation of marine gas hydrate resources, probing into the geological characteristics and distribution laws of marine gas hydrate resources in the South China Sea, and estimate the parameters for in-place resource evaluation, in which the volume method based on Monte Carlo probability was used to evaluate the gas hydrate potential resources in the South China Sea. The probability distribution ranges from 37.6 billion (with 90% probability) to 117.7 billion (with 10% probability) tons of oil equivalent, with an expected value of 74.4 billion tons of oil equivalent. The study results show that the gas hydrate resource density in the South China Sea is similar to that in the typical sea areas, and the estimated global resources are basically consistent with the assessment results at this stag; this shows that the South China Sea has great potential for gas hydrate resources. The research results can provide guidance for the evaluation of global climate change and the exploration and development of hydrate resources.

Finding reliable information online
Our information-saturated environment causes us to spend too much time searching, surfing and organizing the information in our lives. But finding reliable high quality information can be a problem. We are often so buried in information-- and strapped for time-- that we grab the search results without bothering to evaluate its quality. Stebbins shows you how to cut out unreliable information and find online information you can rely on.

Teaching and Un-Teaching Source Evaluation: Questioning Authority in Information Literacy Instruction
This study details the design of library instruction sessions for undergraduate students that intended to encourage critical source evaluation and the questioning of established authorities, and appraises these instructional aims through a thematic analysis of 148 artifacts containing student responses to group and individual activities. The authors found a widespread reliance on traditional indicators of academic and scholarly authority, though some students expressed more personal or complex understandings of source evaluation, trustworthiness, and authorship. Based on the findings, recommendations are made for academic librarians interested in promoting learners' senses of agency and authority.
