Abstract Scientists and natural resource managers require suitable vegetation survey methods to assess the success of rangeland restoration projects. Visual estimation and point intercept methods are commonly used to evaluate vegetation cover. This study compared the performance of one visual (quadrat-based) and two line point intercept (LPI – canopy and basal) methods to assess biodiversity, cover, and to estimate biomass production on sites invaded by introduced annual grasses across Wyoming, USA. Greater species richness and higher Shannon index values were measured in quadrats, while introduced annual and native perennial graminoid cover values were higher in LPI canopy in general. Overall, these outcomes indicate quadrats as the most suitable survey method when biodiversity monitoring is the primary objective, while suggesting LPI canopy when monitoring vegetation cover is prioritized. Finally, our regression models indicated quadrat-based estimates as the most reliable to predict introduced annual and native perennial graminoid biomass.

Natural resource managers need up-to-date information about how people interact with public lands and the meanings these places hold for use in planning and decision-making. This case study explains the use of public participatory Geographic Information System (GIS) to generate and analyze spatial patterns of the uses and values people hold for the Browns Canyon National Monument in Colorado. Participants drew on maps and answered questions at both live community meetings and online sessions to develop a series of maps showing detailed responses to different types of resource uses and landscape values. Results can be disaggregated by interaction types, different meaningful values, respondent characteristics, seasonality, or frequency of visit. The study was a test for the Bureau of Land Management and US Forest Service, who jointly manage the monument as they prepare their land management plan. If the information generated is as helpful throughout the entire planning process as initial responses seem, this protocol could become a component of the Bureau’s planning tool kit.

Professional Roles And Responsibilities

The increasing diversity, complexity and dynamics of ecosystem values and uses over the last 50 years requires new ways for natural resource managers (foresters, wildlife biologists, etc.)to understand and relate to their professional roles and responsibilities in accommodating urban and rural ecosystem users, and managing the complimentary and conflicting interactions between them. Three stages in Western-world natural resources management are identified and analyzed, beginning with the (1) Traditional stage: natural resources first, foremost and forever, to (2) Transitional stage: natural resource management,for better or worse, involves people, to (3) Relationship stage: managing natural resources for valued people and ecosystem relationships. The impacts of these three perspectives on how natural resource managers view and respond to ecosystems,people and other life-forms is basic and can be profound.

Abstract We studied the diet and vegetation composition of Egyptian tortoise, Testudo kleinmanni, habitat in North Sinai, Egypt. Dietary data was recorded through direct observations and the vegetation composition was recorded through the use of quadrats and line transects in 66 sampling points (33 in tortoise areas and 33 in non-tortoise areas). Our results showed that vegetation of Egyptian tortoise habitat had high species richness, Simpson’s diversity index, and vegetation cover in contrast to areas without Egyptian tortoises. These tortoises ate thirty four species of plants, a majority of these being perennials, with most feeding observations occurring in spring and winter. The consumption of perennials may enable Egyptian tortoises to find and consume food in an arid environment with low, variable and unpredictable rainfall. The plants most consumed were rare in our vegetation survey, suggesting food preferences. Our study suggests that Egyptian tortoises, which rely on vegetation for food and refugia, may suffer if vegetation cover and richness decrease.

Objective: Pyelonephritis is the most common non-obstetric cause for hospitalization during pregnancy. The maternal and obstetric complications associated with antepartum pyelonephritis are well-described. However, it is not clear whether these risks extend into the postpartum period. The primary objective of this study was to describe the morbidity associated with postpartum pyelonephritis, by comparing the morbidity associated with pyelonephritis in the postpartum period to morbidity seen during pregnancy or delivery. Methods: A retrospective cohort study was performed using the Nationwide Readmissions Database (NRD), an all-payor sample of discharges from approximately 60% of United States (US) hospitalizations. Discharges between October 2015 through December 2018 were included. Maternity-associated hospitalizations, diagnosis of pyelonephritis, comorbid conditions, and incidence of severe maternal morbidity were identified using ICD-10 diagnosis and procedure codes. Bivariate statistics, weighted to account for the complex survey methods in the NRD, were used to evaluate the association between antepartum, delivery, and postpartum hospital stays associated with pyelonephritis and maternal morbidity. Weighted regression models were used to evaluate the association between admission timing and maternal outcomes. Results: A total of 32,850 pyelonephritis admissions were identified, corresponding to a national estimate of 61,837 admissions. Of these, 1,465 (2.4%) were postpartum, 55,056 (89.0%) were antepartum, and 5,317 (8.6%) involved a delivery stay. Rates of severe maternal morbidity were higher in the postpartum group than the antepartum or delivery hospitalization groups (59.5% vs. 12.9% and 15.8%, respectively, p < 0.001); when compared to antepartum hospitalizations, the adjusted relative risk for composite severe maternal morbidity for postpartum hospitalizations was 4.68 (95% CI: 4.33, 5.05). Most of this difference was driven by rates of sepsis (53.2% vs. 11.0% vs. 10.9%). Conclusions: Though relatively uncommon, postpartum hospitalizations for pyelonephritis are associated with higher rates of severe maternal morbidity, driven by differential rates of sepsis, than are antepartum or delivery-associated hospitalizations.

Abstract. Wadi Yalamlam is known as one of the significant wadis in the west of Saudi Arabia. It is a very important water source for the western region of the country. Thus, it supplies the holy places in Mecca and the surrounding areas with drinking water. The floristic composition of Wadi Yalamlam has not been comprehensively studied. For that reason, this work aimed to assess the wadi vegetation cover, life-form presence, chorotype, diversity, and community structure using temporal remote sensing data. Temporal datasets spanning 4 years were acquired from the Landsat 8 sensor in 2013 as an early acquisition and in 2017 as a late acquisition to estimate normalized difference vegetation index (NDVI) changes. The wadi was divided into seven stands. Stands 7, 1, and 3 were the richest with the highest Shannon index values of 2.98, 2.69, and 2.64, respectively. On the other hand, stand 6 has the least plant biodiversity with a Shannon index of 1.8. The study also revealed the presence of 48 different plant species belonging to 24 families. Fabaceae (17 %) and Poaceae (13 %) were the main families that form most of the vegetation in the study area, while many families were represented by only 2 % of the vegetation of the wadi. NDVI analysis showed that the wadi suffers from various types of degradation of the vegetation cover along with the wadi main stream.

Work Socialization

The primary objective of this essay is to assign a gap in Human Recourse Management literature. Many studies and resources are known about hiring and maintaining people and their loyalty to organizations. Work socialization is the first step to keeping people; however, most of the literature on integration at the workplace focuses primarily on organizational commitment and not on the individuals. Various perspectives of work socialization have been discussed including socialization stages, guidance and carrier development. This essay focuses on the approach of Human Resource Management, but the scope is expanded to the individual as well. In this paper, the reasoning, the methods and the questions of my future doctoral research on integration at the workplace are analysed. First, the issue is discussed from the perspective of social changes in Hungary. The next part of this essay illustrates varying definitions from the literature, providing then my own view of how to explain the integration process in the workplace and through which what I would like to focus my research. This article also aims to show possible methods (in-depth interviews with Human Resource Managers and document analysis) for examining the topic at multinational pharmaceutical factories in Hungary, while highlighting the most important questions for which my research aims to find answers.

The development of online payment systems such as the online payment point system has greatly assisted the public in processing monthly transactions such as water bills. However, in its application, this system still uses large devices such as computers and inkjet printers so that the operation takes a long time and is less efficient. Therefore, in this study, a mobile application is designed to replace the role of computers in making water bill payment transactions in the online payment point system (SOPP) of PDAM Malang Regency. The application that is connected to a database server via the internet is also integrated with a compact wireless thermal printer that can be carried anywhere and does not require ink refills so that it can speed up the transaction process and be more efficient in time, paper and space. The research method used was experimental and survey methods. The experimental method is used to test the running of the application, test the application's compatibility with the device and measure the time it takes for the application to exchange data. The survey method is used to test user satisfaction with the application.

Stewardship Behavior

<i>Abstract</i>.—Contemporary definitions of aquatic resource stewardship are a specific expression of ethical themes that humankind has wrestled with for millennia. The foundations for a stewardship ethic can be secular or spiritual. Other chapter contributors discuss a range of the secular foundations (e.g., fishing, boating); we discuss the implications of stewardship ethics rooted in religious traditions. Some fisheries professionals recognize religious–cultural influences on aquatic stewardship, such as those seen in Native American or Asian immigrant communities. But fisheries professionals have commonly ignored mainline Judeo-Christian faith traditions as an ethical basis for aquatic stewardship behavior, despite the fact that those traditions inform ethical development for large numbers of people in North America and that denominations within those traditions have increasingly engaged in stewardship-based environmental education and advocacy. The proposition that religious values often form the basis for a stewardship ethic presents several challenges for fisheries professionals striving to foster stewardship behavior. However, a basic understanding of these religious foundations could contribute to an improved practice of stewardship education, through outreach to a new constituency—faith communities. To illustrate this point, we briefly summarize some of the sources for stewardship found in the biblical corpus. We offer three examples of how Christian stewardship principles are manifest in aquatic stewardship programs delivered by faith communities. Models of partnership between natural resource managers and local faith communities are emerging across North America. In revisiting the ethical bases of stewardship and identifying new opportunities for stewardship education partnerships, we hope to demonstrate one more means by which fisheries professionals can bridge from stewardship education in principle to an effective practice of stewardship education.
