Objective: To describe some reproductive management programs that allow increasing the productive efficiency of ewes. Design/methodology/approach: Description of the main hormones and their application in sheep reproductive management protocols. The subjects are reviewed based on academic references as well as on their use in sheep reproductive protocols at the Sheep and Goat Reproduction Laboratory of the Colegio de Postgraduados, Mexico. Results: Hormones, socio-sexual strategies, reproductive protocols and techniques are tools that improve the reproductive efficiency of ewes during the reproductive season and seasonal anestrus. Study limitations/implications: The basic techniques of reproductive management and protocols in sheep are mostly available, however, they still have room for improvement, therefore, multiple efforts involving all participants, such as the primary sector, public and private institutions, are required. Findings/conclusions: Reproductive management is an important pillar for animal production; thus its implementation is fundamental to improve the reproductive and productive efficiency of a herd

Objective: To describe the management strategies of controlled suckling and the male effect to reduce postpartum anestrus, and to show the participation of kisspeptin to regulate the effect of both factors. Design/Methodology/Approach: A review of scientific publications was conducted, in order to show the importance of suckling and the male effect as strategies to reduce postpartum anestrus in the ewe, as well as the relation of kisspeptin with both factors. Results: Seasonal anestrus can be avoided with the use of breeds adapted to the local environment, such as Pelibuey. Postpartum anestrus occurs mainly as a result of suckling, since the latter inhibits the pulsating secretion of the gonadotropin-releasing hormone (GnRH) and the luteinizing hormone (LH). The exact path of this inhibition is unknown, although it seems that endogenous opioid peptides and kisspeptin are intermediaries. Controlled suckling and the male effect are management strategies that improve the reproductive behavior of postpartum ewes. Kisspeptin regulates the influence of the male effect through the secretion of GnRH/LH. Study Limitations/Implications: To understand the impacts of suckling and the male effect on the duration of postpartum anestrus, as well as the participation of kisspeptin in the regulation of both effects, will allow designing management strategies to improve the reproductive efficiency of the ewes. Findings/Conclusions: Controlled suckling and the male effect reduce postpartum anestrus and improve the reproductive behavior of the ewes; advancing knowledge of the kisspeptin effect could improve the effectiveness of both techniques.

Objective: To describe briefly the physiology, the anatomy and the reproductive management of the ram. Design/Methodology/Approach: Review of the anatomy, physiology and general considerations for an adequate reproductive management of the ram. Results: The ram presents a less seasonal reproductive activity than the female and its reproductive behavior is easier to observe. However, it is in the fall, the reproductive season of seasonal sheep, when their behavior is much more complex and complete. It begins with smelling the external genitals of the female, goes through the flehmen response and ends with mating, intromission and ejaculation. It is necessary to consider the anatomical and physiological aspects of the ram and its meticulous management to avoid reproductive failures in the flock. Frequently, the rams are less important for the flock’s handler during the season of reproductive rest. Monitoring their diet and parasite and disease control is necessary to keep them apt for reproduction. The evaluation of the reproductive aptitude of the ram before mating is convenient and can be planned as part of its management; and once mating begins, considering the adequate proportion of rams/females, in addition to monitoring their performance during this event. Study Limitations/Implications: To consider that the ram shows a good capacity for mating, capacity for service, libido, quality of semen, since it is responsible for a proportion of lamb production. Findings/Conclusions: Reproduction in sheep is regulated by the photoperiod, genetic potential, nutritional status, health status and other factors, which are important both in the ram and in the female. Some sheep breeds have potential of prolificacy; a good reproductive management of the ram can influence these factors and increase the reproduction rate in the flocks.

Skilled birth attendance and institutional delivery have been advocated for reducing maternal, neonatal mortality and infant mortality (NMR and IMR). This paper examines the role of place of delivery with respect to neo-natal and infant mortality in India using four rounds of the Indian National Family Health Survey conducted in 2015–2016. The place of birth has been categorized as “at home” or “public and private institution.” The role of place of delivery on neo-natal and infant mortality was examined by using multivariate hazard regression models adjusted for clus-tering and relevant maternal, socio-economic, pregnancy and new-born characteristics. There were 141,028 deliveries recorded in public institutions and 54,338 in private institutions. The esti-mated neonatal mortality rate in public and private institutions during this period was 27 and 26 per 1000 live births respectively. The study shows that when the mother delivers child at home, the chances of neonatal mortality risks are higher than the mortality among children born at the health facility centers. Regression analysis also indicates that a professionally qualified provider′s antenatal treatment and assistance greatly decreases the risks of neonatal mortality. The results of the study illustrate the importance of the provision of institutional facilities and proper pregnancy in the prevention of neonatal and infant deaths. To improve the quality of care during and imme-diately after delivery in health facilities, particularly in public hospitals and in rural areas, accel-erated strengthening is required.

Wastewater surveillance for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emerging approach to help identify the risk of a coronavirus disease (COVID-19) outbreak. This tool can contribute to public health surveillance at both community (wastewater treatment system) and institutional (e.g., colleges, prisons, and nursing homes) scales. This paper explores the successes, challenges, and lessons learned from initial wastewater surveillance efforts at colleges and university systems to inform future research, development and implementation. We present the experiences of 25 college and university systems in the United States that monitored campus wastewater for SARS-CoV-2 during the fall 2020 academic period. We describe the broad range of approaches, findings, resources, and impacts from these initial efforts. These institutions range in size, social and political geographies, and include both public and private institutions. Our analysis suggests that wastewater monitoring at colleges requires consideration of local information needs, sewage infrastructure, resources for sampling and analysis, college and community dynamics, approaches to interpretation and communication of results, and follow-up actions. Most colleges reported that a learning process of experimentation, evaluation, and adaptation was key to progress. This process requires ongoing collaboration among diverse stakeholders including decision-makers, researchers, faculty, facilities staff, students, and community members.

Governance Architecture

Most research on global governance has focused either on theoretical accounts of the overall phenomenon or on empirical studies of distinct institutions that serve to solve particular governance challenges. In this article we analyze instead “governance architectures,” defined as the overarching system of public and private institutions, principles, norms, regulations, decision-making procedures and organizations that are valid or active in a given issue area of world politics. We focus on one aspect that is turning into a major source of concern for scholars and policy-makers alike: the “fragmentation” of governance architectures in important policy domains. The article offers a typology of different degrees of fragmentation, which we describe as synergistic, cooperative, and conflictive fragmentation. We then systematically assess alternative hypotheses over the relative advantages and disadvantages of different degrees of fragmentation. We argue that moderate degrees of fragmentation may entail both significant costs and benefits, while higher degrees of fragmentation are likely to decrease the overall performance of a governance architecture. The article concludes with policy options on how high degrees of fragmentation could be reduced. Fragmentation is prevalent in particular in the current governance of climate change, which we have hence chosen as illustration for our discussion.

This chapter gives a rapid overview of the history of Roman public and private institutions, from their early beginning in the semi-legendary age of the kings to the later developments of the Imperial age. A turning point has been the passage from the kingdom to the republic and the new foundation of citizenship on family wealth, instead of the exclusiveness of clan and lineages. But still more important has been the approval of the written legislation of the XII Tables giving to all citizens a sufficient knowledge of the Roman legal body of consuetudinary laws. From that moment, Roman citizenship was identified with personal freedom and the rule of law. Following political and military success, between the end of IV and the first half of III century bce Rome was capable of imposing herself as the central power in Italy and the western Mediterranean. From that moment Roman hegemony was exercised on a growing number of cities and local populations, organized in the form of Roman of Latin colonies or as Roman municipia. Only in the last century bce were these different statutes unified with the grant of Roman citizenship to all Italians. In this same period the Roman civil law, which was applied to private litigants by the Roman praetors, had become a very complex and sophisticated system of rules. With the empire the system did not change abruptly, although the Princeps did concentrate in his hands the last power of the judiciary and became the unique source of new legislation. In that way, for the first time, the Roman legal system was founded on rational and coherent schemes, becoming a model, which Antiquity transmitted to the late medieval Europe.

Purpose – The purpose of this paper is to explore the potential differences between types of self-service technology. Specifically, the paper explores how the dynamics of public and private self-service technology influence customers' decision to use the technology. Design/methodology/approach – Existing customers of private and public self-service technology were surveyed from the same industry. Using structural equation modeling, the authors examine how relevant self-service constructs influence evaluations and attitudes of customers across both settings. Findings – The analysis reveals that customers' control and convenience perceptions differ across public and private self-service technology. Additionally, customers placed a heavier emphasis on the hedonic or utilitarian evaluation of a service experience based on the type of self-service technology. Practical implications – For managers of self-service applications, understanding the unique differences of public and private self-service technology can aid in the implementation and adoption of the technology. By properly understanding the differences of the self-service types, managers can provide a beneficial experience to the customer. Originality/value – By identifying and describing two distinct categories of SSTs, this study allows managers and researchers to better understand how and why individuals choose to utilize individual self-service technologies. Through understanding the unique dynamics of a public and a private SST experience, retailers can determine the appropriate strategy for customer adoption based on the utilitarian or hedonic functions of the technology.

Educational technology plays a fundamental role in enhancing teaching learning process. It has facilitated instructional process and made it more productive, dynamic and effective. Therefore the study was conducted to explore the role of educational technology in public and private institutes in district Karak (Khyber Pukhtunkhwa) Pakistan in comparative perspectives. The main objectives of the study were: to compare the availability of educational technology in public and private institutions at secondary level; to compare the usability of educational technology in public and private institutions at secondary level and to know the usefulness of educational technology in public and private institutions at secondary level. All the heads, teachers and students in public and private secondary schools in district Karak constituted the population of the study. In order to ensure adequate sample, 60 heads, 180 teachers and 600 students serving and studying in public and private sectors at secondary school level in District Karak were selected randomly. The study was delimited to the selected male public and private secondary schools. The study was also delimited to those technologies which are commonly used. The study was descriptive in nature therefore, the researchers decided to develop questionnaire for the collection of data. A single questionnaire was developed for the whole sample. Pilot testing was conducted to know the weakness, misconceptions and ambiguities of the questions. After conduction of pilot testing, the questionnaire was revised and then its final version was prepared in the light of valuable suggestions of the heads, teachers and students. The researchers personally visited to the respective sample and distributed the questionnaires among the heads, teachers and students in public and private secondary schools. In this way data was collected. After the collection of data, the data was organized, tabulated and analyzed. The researchers decided to apply chi-square for the statistical treatment of the data. Therefore, chi square was applied to compare the responses of the sample. After analysis of the data, it was concluded that educational technologies are not available in both sectors. Some technologies are available in minor amount but these technologies are not used in both public and private sectors. Key Words:Educational Technology, Availability of Educational Technology, Usability of Educational Technology, Importance of Educational Technology
