Abstract
The purpose of this study was to investigate the monitoring and evaluation of teacher effectiveness a case of Teacher Performance Appraisal and Development tool (TPAD) in public secondary schools in Nyandarua South Sub-county, Nyandarua County, Kenya. The study was set to achieve three objectives; To determine the influence of teacher clog in and clog out exercise on teacher performance in public secondary schools in Nyandarua South Sub-county, Nyandarua county Kenya, to examine the influence of teachers’ class registers on teacher performance in public secondary schools and to determine the influence of teachers adherence to school deadlines on their performance in public secondary schools. The study was guided by Performance Appraisal Model and benefited from descriptive survey research design. The target population was all 18 public secondary schools in Nyandarua south sub-county. The respondents were 18 Principals, 18 deputy Principals 20 H.O.D s and 90 teachers being a sample size of 30 percent of the entire public school population. Teachers were sampled using simple random sampling to obtain five teachers in every sampled school, totaling to 90 teachers. Questionnaires, interview guide and document analysis guide formed the instruments used for data collection. Descriptive statistics was used to analyze collected data. The study findings revealed that monitoring of teachers on their reporting on duty and leaving from duty improved the teachers stayed in school hence more contact time between teachers and learners in school, the monitoring of teacher class attendance improved teachers’ syllabus coverage. A majority of the schools are completing the syllabus coverage in time. The teachers are now able to do revision as they prepare students for examinations and promotion to the next grades. The meeting of deadlines has created a positive culture among the teachers in the schools. The teachers now look at meeting the deadlines set by the schools as a good thing that is making them more responsible. Lastly the strategies being used to monitor teachers attendance on their duties has resulted into impressive performance of teacher in their duties. Based on the findings and Conclusions of the study, it is recommended that TPAD tool for monitoring teachers on time management should be emphasized. The practice should be borrowed and applied to other areas of school operations.

Full textAbstract:
Automated temporal planning is the technology of choice when controlling systems that can execute more actions in parallel and when temporal constraints, such as deadlines, are needed in the model. One limitation of several action-based planning systems is that actions are modeled as intervals having conditions and effects only at the extremes and as invariants, but no conditions nor effects can be specified at arbitrary points or sub-intervals.In this paper, we address this limitation by providing an effective heuristic-search technique for temporal planning, allowing the definition of actions with conditions and effects at any arbitrary time within the action duration. We experimentally demonstrate that our approach is far better than standard encodings in PDDL 2.1 and is competitive with other approaches that can (directly or indirectly) represent intermediate action conditions or effects.

Abstract The lowland area of the southeastern part of the Carpathian Basin is exposed to extreme hydrological conditions. The monitoring and analysis of the excess inland water are necessary in order to understand the scope and direction of the development of this type of flooding. When solving the problem of the drainage of an area and dimensioning drainage systems, one of the most important steps is to calculate the rate of runoff. Before calculating the rate of runoff, it is necessary to perform various analysis such as: hydrological, hydrogeological, pedological and land use analysis. The use of empirical formulas by different authors is one of the methods for determining the rate of runoff. These formulas can be of regional character, while some are applicable in different parts of the world. In this paper, the runoff coefficient and rate of runoff were calculated as indicators of the efficiency of the area drainage, employing the formulas by Nemet and Turazzo. The emphasis was put on the usage of modern tools and databases of soil characteristics while using a “traditional” method to determine rate of runoff. The obtained results demonstrate that the rate of runoff which reflects the current state of the drainage basin is very similar to the rate of runoff used for dimensioning of drainage system. The problem of retaining smaller amounts of water that remains even after the anticipated drainage deadlines can be solved with the regular maintenance of amelioration canals and additional ameliorative measures.

"From Monitoring and Modeling to Management: How to Improve Water Quality in Brazilian Rivers? A Case Study: Piabanha River Watershed." Water 13, no. 2 (January 13, 2021): 176. http://dx.doi.org/10.3390/w13020176.
Full textAbstract:
Water quality has been a global concern, as evidenced by UN Sustainable Development Goals. The current paper has focused on the Piabanha River rehabilitation as a case study which can be generalized to other similar watersheds. A monitoring program during a hydrological year was carried out, and different databases were used to calibrate and validate the QUAL-UFMG water quality model. Sanitation is the major problem in the watershed, notably in its headwater catchments, which concentrate the most urbanized regions where water quality is worse in the dry season due to low river flows. Thus, simulations of the river water quality have been performed through computational modeling suggesting organic load reductions in some sub-basins. In conclusion, some strategies to improve water quality have been discussed: (i) The water quality rehabilitation must consider progressive goals of pollution reduction starting with an initial implementation in a reduced area. The monitoring should be based on a few parameters relevant and simple to monitor. (ii) Pollution reduction ought to be carried out strategically with deadlines and intermediate goals that must be agreed upon between the stakeholders in the watershed. (iii) Watershed committees should supervise projects to improve water quality in partnership with the State Prosecutor’s Office.

International Journal of Electrical and Computer Engineering (IJECE) 10, no. 6 (December 1, 2020): 6380. http://dx.doi.org/10.11591/ijece.v10i6.pp6380-6388.
Full textAbstract:
Demand robust counterpart-open capacitated vehicle routing problem with time windows and deadline (DRC-OCVRPtw,d) model formed and explained in this paper, is the model used to find the minimum distance and the time needed for vehicles to transport garbage in Sukarami Sub-District, Palembang that consists of the time it takes for the vehicle to pass through the route. Time needed to transport garbage to the vehicle is called time windows. Combination of the thoses times is called deadline. The farther
the distance passed by vehicle and the more garbage transported, the longer the deadline is needed. This DRC-OCVRPtw,d model is completed by LINGO 13.0 to obtain the optimal route and time deadline for Sukarami Sub-District. The model shows that the improved model of open vehicle routing problem involving the robustness, time windows and deadline can achieve the optimal routes that enable driver to save operational time in picking up the garbage compared to similar problem not involving no-time windows and deadline stated in previous research.

International Journal of Basic & Clinical Pharmacology 6, no. 4 (March 25, 2017): 739. http://dx.doi.org/10.18203/2319-2003.ijbcp20171081.
Full textAbstract:
Background: Some studies of the characteristics of the calcium-phosphorus metabolism changes in experimental hypothyroidism given the phenotype of acetylation will allow to more effectively diagnose, predict the course and to carry out prevention and treatment of hypothyroidism and the accompanying pathological changes.The aim is to trace the dynamics of phosphorus-calcium metabolism and the level of serum iron in experimental hypothyroidism and to determine the severity of it changes depending on the type of acetylation.Methods: In experiments were used rats weighing 180-220g, who were divided into 2 main groups depending on the type of acetylation on α - slow and β - fast metabolizer (acetylators). Each group was modelled experimental hypothyroidism by the introduction of mercazolil at a dose of 5 mg, for 14 days. Each group was divided into 5 subgroups depending on the time of the study. Group of α-slow metabolizers (acetylators) were divided into the following subgroups: Iα - intact IIα - at the 4th hour of the study, IIIα - on the 1st week of the study, IVα - 2-week studies, Vα - on the 3rd week of the study.Results: In the study of the calcium concentration at the 4th hour of the study in subgroups with α - and β - acetylation phenotypes were observed the decrease by 12.0% and 10.5% respectively, and its level in the IIβ - subgroup was 5.3% lower than the IIα- subgroup. The concentration of calcium ions in Vα subgroup was lower than in the Iα sub-group was 12.0%, and the level of calcium in the blood serum of animals Vβ was lower compared to Iβ IIβ IIIβ Ivβ-90.9%, 72.7%, 80.0%, 80.9% respectively. Also relatively, Vα Vβ subgroups in the subgroup calcium concentration were lower at 81.8 percent.Conclusions: Belonging to a particular phenotype of acetylation affects the degree of severity of the changes of indices of calcium-phosphorus metabolism and serum iron in experimental hypothyroidism, the most significant differences between the values of their indicators were detected early and deadlines of the study.

Full textAbstract:
Purpose The purpose of this paper is to perform a quantitative analysis of the literature in order to determine the main causes of delay in construction projects. Design/methodology/approach A set of 47 articles from the literature were analyzed, yielding 1,057 different causes of delay. In order to analyze and compare the main causes of delay, their degree of impact was studied statistically. Next, a mention count method was used to determine the primary causes of construction project delays and through the use of Pareto diagrams, the main causes of delays in construction projects were determined. Findings It was determined that the three main causes of construction project delay are problems that occur during execution, administrative problems and labor conflicts; together they account for almost 80 percent of the causes found in the literature. Moreover, it was deduced that problems during execution are based on unpredictable events, while administrative problems are rooted in poor cash flow management. In addition, seven sub-groups of delay causes were identified as being major due to the number of mentions detected. These were “Changes during construction,” “Poor construction management,” “Construction errors,” “Economic/Financial,” “Conflict/Relationship” and “Lack of experience.” Practical implications This study provides a unique classification method, which was successfully validated, for the causes of construction project delay. Thanks to the classification, designers may use this information as a starting point for designing future construction projects, thereby minimizing the appearance of unforeseen events during construction. Moreover, the results of this study will help project managers be aware of the possible causes of delay that may affect their construction projects. This understanding can help them identify potential risks in the initial phases of the project and allow decisions to be made early before problems arise or the consequences of the deviations become irreparable. The results can also serve as input for the development of future management improvement methodologies that are aimed at reducing costs and ensuring that deadlines are met. Social implications Identifying the factors and causes of the delays will allow mitigation actions to be taken in order to avoid delays, which will ultimately allow homes, schools, hospitals and other necessary infrastructure to be delivered on time or even before the planned date. Originality/value This study provides a unique classification method that was successfully validated. Thanks to the classification, designers may use this information as a starting point for designing future construction projects, thereby minimizing unforeseen events during construction.

Full textAbstract:
AimsPsychosis research has largely focused on symptoms which are easier to define. Symptoms which are challenging to detect and articulate, including disturbances in the basic- and bodily-self, may not be volunteered by patients, despite causing significant distress. Increased understanding of such symptoms, which may present in the prodromal phase of psychosis and persist following the remission of positive symptoms, may allow patients who experience these to be better supported.This study aims to explore how disturbances in the basic- and bodily-self relate to multimodal hallucinations. Through sampling a non-clinical population, this study takes the continuum approach to psychosis, where individuals experience sub-clinical psychotic symptoms which do not cause distress or functional impairment.It is hypothesised that individuals with greater hallucination proneness will exhibit greater severity of ambiguous and imprecise mapping of bodily experiences, and will report greater levels of basic and bodily-self disturbance. This project also aims to evaluate Audiograph as a newly developed tool for creating representations of visual hallucinations.MethodThis is a two-stage cross-sectional study. In stage one, participants completed the Multi-Modality Unusual Sensory Experiences Questionnaire to assess hallucination-proneness. In stage two, all participants were invited to complete seven further validated questionnaires which assessed basic- and bodily self-disturbances alongside co-variates including anxiety and depression symptoms, delusion-proneness and loneliness. Participants also completed emBODY, a computer-based task which allows participants to map the bodily sensations they experience during 13 different emotional states. Participants with high-hallucination proneness also completed the Audiograph task. Hierarchical linear regression, conducted using Stata, will be used to model the influence of hallucination proneness on measures of basic- and bodily-self disturbance. MATLAB will be used to generate topographical maps of the data from emBODY; maps will be compared between different emotional states using linear discriminant analysis, and between high and low hallucination proneness groups using Spearman's test.ResultCurrently, 50 of the 104 stage one participants have completed stage two.Since this project comprises a compulsory component of the presenting author's intercalated degree, data collection will cease on the 29th of March in advance of their poster and write-up submission deadlines in May.ConclusionAlthough basic- and bodily-self disturbances have been assessed in previous studies using various techniques, no single study has assessed these alongside multimodal hallucinations to link these concepts together as a whole, especially not in a general population sample. The added value of this project is to precisely address this gap in knowledge.

Full textAbstract:
In this study, a work process model for animation production is developed. Interviews with animation studio workers and surveys of their working diaries and shot progress charts are conducted to create a framework for the work processes. The work hours necessary for each operation of the work project are expressed using a gamma function. Workers are classified into two categories, managers and animators, and their behavioral rules are modeled. To establish a rule for the determination of the operation sequence order for an animator to perform multiple work operations, four typical dispatching rules, often used in a scheduling theory, are selected, and the one that is closest to actual data is regarded as the rule that the animator actually follows. As a result of the analysis, it is found that the Earliest Due Date (EDD) and SLACK are closest to actual animators’ behavioral rules. Managers are also found to move the sub-deadline (a deadline of each operation) up about 30% earlier than the actual deadline. The knowledge we obtain is that, in order to realize better working conditions, animators should determine their operation sequence order by using SLACK, and managers should designate subdeadlines by keeping a balance between the prevention of deadline violation and the reduction of overtime work.

Full textAbstract:
Cloud computing realizes the long-held dream of converting computing capability into a type of utility. It has the potential to fundamentally change the landscape of the IT industry and our way of life. However, as cloud computing expanding substantially in both scale and scope, ensuring its sustainable growth is a critical problem. Service providers have long been suffering from high operational costs. Especially the costs associated with the skyrocketing power consumption of large data centers. In the meantime, while efficient power/energy utilization is indispensable for the sustainable growth of cloud computing, service providers must also satisfy a user's quality of service (QoS) requirements. This problem becomes even more challenging considering the increasingly stringent power/energy and QoS constraints, as well as other factors such as the highly dynamic, heterogeneous, and distributed nature of the computing infrastructures, etc.
In this dissertation, we study the problem of delay-sensitive cloud service scheduling for the sustainable development of cloud computing. We first focus our research on the development of scheduling methods for delay-sensitive cloud services on a single server with the goal of maximizing a service provider's profit. We then extend our study to scheduling cloud services in distributed environments. In particular, we develop a queue-based model and derive efficient request dispatching and processing decisions in a multi-electricity-market environment to improve the profits for service providers. We next study a problem of multi-tier service scheduling. By carefully assigning sub deadlines to the service tiers, our approach can significantly improve resource usage efficiencies with statistically guaranteed QoS. Finally, we study the power conscious resource provision problem for service requests with different QoS requirements. By properly sharing computing resources among different requests, our method statistically guarantees all QoS requirements with a minimized number of powered-on servers and thus the power consumptions. The significance of our research is that it is one part of the integrated effort from both industry and academia to ensure the sustainable growth of cloud computing as it continues to evolve and change our society profoundly.

The last years of the 20th century were tough times for selling food to Europeans. The competition was fierce, the rules uncertain, and the retail markets picky. It was not just that huge supermarket chains had come to dominate food retailing, and to demand products conforming to ever-higher standards of convenience and aesthetic quality; these trends were common across the industrialized world. In addition, they demanded that the suppliers of those products— farmers and manufacturers, but also a range of intermediaries—meet standards of hygiene and accountability that were unimaginable twenty, even ten years earlier. The supermarkets wanted assurances that none of their products would set off another food scare; too many had already shaken European consumers’ faith in the supermarkets’ increasingly globalized offerings. On the supermarket shelves, these assurances might appear as new labels or packaging, if they appeared at all. What consumers largely did not see was the work that went into providing them with food as certifiably pure as it was pretty. This work took place on farms and in packhouses; in consultants’ offices and corporate boardrooms; in activists’ meetings and chemical analysts’ laboratories. It demanded long flights, short deadlines, and nonstop vigilance. Above all, the work of assuring the overall goodness of globalized food required all kinds of people and things to deal with each other in new ways, and often across great distances. In this sense, it transformed the social relationships of food provisioning on both an interpersonal and transcontinental scale. This book explores how these changes took shape within two fresh vegetable trades, or commodity networks, linking two Sub-Saharan African countries to their former European colonial powers. The francophone network brings Burkina Faso’s green beans to France, while the anglophone network brings an assortment of prepackaged fresh vegetables from Zambia to the United Kingdom. Broadly similar in some ways, they differ radically in others, including the ways that they experienced Europe’s late twentieth-century food scares. By exploring the history of these differences and how they are sustained and transformed in specific places, practices, and social institutions, I hope to illuminate the relationship between culture and power in globalized food provisioning.

Word counts and press deadlines join with the argument of the book to insist on the less amusing but perhaps more radical task of integrating the two. If this causes any dissonance, the tension only reflects something of that which Chinese theologians have faced as they tried to write of and conceive of a Christian God in a language in which the concepts did not readily exist and in literary forms that bore little relation to those in which they themselves had inherited the gospel....

The Sunday newspaper is an often-neglected success story of the twentieth century news media landscape. The popularity and profitability of Sunday papers grew throughout the century to establish themselves as flagships of cultural and commercial trends and an essential complement to most national daily productions. On account of their production cycle, Sunday newspapers were always able to do things that the daily press with its punishing routines and pressure of deadlines were never able to achieve. Mapped onto the characteristic social class and politically stratified perspectives of British and Irish newspaper reading publics, the Sunday newspaper became a prominent vehicle for the experiments in layout and content after the full computerization of newspapers in the mid-1980s; lifestyle, commentary, colour photography all were pioneered in this format. The range of geographical variants of the Sunday newspaper are also considered from the regional Sunday Sun published in Newcastle from 1919 to the Irish Sunday Independent and Scottish Sunday Post to the migration of English titles across Britain into Ireland with increasing national specialization in their content and appeal. The chapter also considers the varying reasons for the failure of high-profile Sunday papers such as the Sunday Correspondent and the News of the World.

The migrant is, according to philosopher Thomas Nail, ‘the political figure of our time.’1 Perhaps nowhere is this more the case in the early twenty-first century than in the former lands of the Ottoman Empire. From Libya to Iraq, Yemen to Macedonia, the Middle East has become the epicentre of the greatest migrant and refugee crisis in generations. Countries throughout the region struggle to cope with swelling populations of displaced people, many of whom have been left to languish in squalid camps with little access to food, water, medical treatment or education. Exacerbating the situation are the efforts of many states, especially those located on the frontiers of the European Union, to close their borders, effectively stranding millions of migrants and refugees in transit. The militarisation of land and sea borders separating North Africa and the Middle East from the European Union has contributed to the emergence of a vast smuggling industry, particularly along the Mediterranean rim. Desperate migrants pay often exorbitant fees to smugglers who are eager to adopt ever-riskier strategies to assist their clients, while also avoiding capture. These dynamics have led one prominent scholar of migration to refer to the Mediterranean as ‘the world’s deadliest border.’...

Full textAbstract:
As new technologies continue to emerge, firms in diverse industries increasingly must respond. Future economic rents and competitive advantage rests on the organizational ability to assimilate new technologies in the right manner. Broadcasters, content and service providers, packaging providers, and many other firms have been affected by the advent of digital technologies in the digital television (DTV) industry. All these firms have considered the adoption of digital technologies. Digital television is a new television service representing the most significant development in television technology since the advent of color television in the 1950s (Kruger, 2005). DTV can provide several benefits: sharper pictures, a wider screen, CD-quality sound, better color rendition, integration with Web technologies, increased programming options, easy integration between broadcasting networks and broadband telecommunication networks (e.g., B-ISDN—Integrated Services Digital Network), and other new services currently being developed. The nationwide deployment of digital television is a complex and multifaceted enterprise though. It has a profound impact on the entire TV system: from the offer typologies to the consumption manners. Therefore, a successful deployment requires the development by content providers of compelling digital programming; the delivery of digital signals to consumers by broadcast television stations, as well as cable and satellite television systems; and the widespread purchase and adoption by consumers of digital television equipment (Kruger, 2005). In sum, the advent of the digital television has caused an actual breakthrough innovation on almost all levels of the value chain. Although the adoption of breakthrough innovations is highly risky to pursue, research has shown that firms always follow them (Charitou & Markides, 2003; Ketchen, Snow, & Hoover, 2004). In the case of the television industry, the adoption also happens because the government and the telecommunication regulatory agencies in many countries have foreseen deadlines for the complete transition from analog to digital technologies in this industry. Despite lingering standardization issues, digital transmission is replacing analog transmission in the three major delivery platforms (terrestrial, cable, and direct broadcast satellite [DBS]) (Galperin & Bar, 2002). Therefore, in the future we expect that all firms in this industry will have adopted these digital technologies. Furthermore, this adoption will vary according to both the firm’s activities and the type of breakthrough innovation. This research will present some theoretical arguments to describe the adoption of the digital technology by two different activities in the digital TV industry: TV channels and content providers. These two different types of firms were chosen because the emergence of the digital TV has meant the adoption of different types of breakthrough innovation for each one of them. The next section defines these different types of breakthrough innovation. The two following sections describe the two cases of the adoption of DTV: by TV channel and by content provider. Finally, the last section presents the conclusion and implications of this research.

SCRUM framework is an agile technique that is widely used by development teams in order deliver incremental value to customers and dynamically react to project needs. SCRUM framework might be adapted to conform the development team specificities. In the context of an industry project, we have found that an inexperienced development team frequently faced difficulties with estimating the time needed to complete tasks, which led to missed deadlines in most of the projects. Such problem hampers the risk management and degrades the relationship with the customer. Upon closer analysis, it was identified that the main reason to this issue was the team's inability to breaking down a larger task into smaller sub-tasks and associate a realistic workload to each part. Then, based on traditional techniques, a structured approach to workload estimation was introduced in the SCRUM planning meeting to leverage the team's estimation skill. This approach was implemented in two development projects and increased the accuracy in the estimate defined by the team, yielding realistic schedules and increasing technical visibility.

Full textAbstract:
Transferências de Dados em Massa (BDT) e sua generalização, Múltiplas Transferências de Dados em Massa (MBDT), são serviços críticos para o funcionamento dos negócios nas redes inter centro de dados geo-distribuídas. Nessas redes, aplicações do tipo BDT ou MBDT realizam sincronizações, ressincronizações, replicação de dados, migração de máquinas virtuais e agregação big data, entre outras tarefas, exigindo grandes quantidades de largura de banda e soluções eficientes de engenharia de tráfego. As Redes Ópticas Elásticas (EON) permitem o provisionamento e alocação de recursos sob demanda por meio do Roteamento e Alocação de Espectro (RSA). Este trabalho propõe e compara soluções dinâmicas de RSA cientes da aplicação, que empregam as técnicas de escalonamento Smallest Deadline First (SDF), Larger Data Amount (LDA), Smallest Data Amount (SDA) e Smallest Remaining Time (SRT).
