The Contribution of Individual Characteristics of Managers to the Success of Equivalency Education Programs of the Community Learning Center in Indonesia

The community learning center provides a means of completing compulsory education and increasing the level of educational participation in Indonesia. Through this program, regardless of age, people can continue their education to a level equivalent to junior or senior high school. However, factors that contribute to the success of the program are still in question. This study aimed to determine the contribution of individual characteristics, including work experience, work perception, work motivation, and work discipline, to the success of the equivalency education program at the community learning center. This research was conducted in East Java using a quantitative approach and an explanatory research design. The research sample was taken from 101 program managers through random sampling techniques and the Slovin formula. The data were collected using a questionnaire and then analyzed using multiple regression techniques. The results showed that the education program had high success, with the participants achieving examination pass rates of 96.4% in package B, which is equivalent to junior high school, and 98.2% in package C, which is equivalent to senior high school. The average involvement of community members in the program implementation was 68.6%, and the financial support reached 75.5%. The work experience, work perception, work motivation, and work discipline of the program managers had a significant effect, both simultaneously and partially, on the success of the equivalency education program. In addition, the four independent variables also had a significant predictive effect on the dependent variable, with a simultaneous contribution of 53.8%. Based on these findings, it was recommended that these factors be considered to improve the success, sustainability, and development of education programs at the community learning center.
Ultra-Large-Scale Systems: The Software Challenge of the Future

Abstract : The U. S. Department of Defense (DoD) has a goal of information dominance to achieve and exploit superior collection, fusion, analysis, and use of information to meet mission objectives. This goal depends on increasingly complex systems characterized by thousands of platforms, sensors, decision nodes, weapons, and warfighters connected through heterogeneous wired and wireless networks. These systems will push far beyond the size of today s systems and systems of systems by every measure: number of lines of code; number of people employing the system for different purposes; amount of data stored, accessed, manipulated, and refined; number of connections and interdependencies among software components; and number of hardware elements. They will be ultra-largescale (ULS) systems. The sheer scale of ULS systems will change everything. ULS systems will necessarily be decentralized in a variety of ways, developed and used by a wide variety of stakeholders with conflicting needs, evolving continuously, and constructed from heterogeneous parts. People will not just be users of a ULS system; they will be elements of the system. Software and hardware failures will be the norm rather than the exception. The acquisition of a ULS system will be simultaneous with its operation and will require new methods for control. These characteristics are beginning to emerge in today s DoD systems of systems; in ULS systems they will dominate. Consequently, ULS systems will place unprecedented demands on software acquisition, production, deployment, management, documentation, usage, and evolution practices.
Proactive cyberfraud detection through infrastructure analysis

Internet users are threatened daily by spam, phishing, and malware. These attacks are often launched using armies of compromised machines, complicating identification of the miscreants behind the attacks. Unfortunately, most current approaches to fight these problems are reactive in nature, allowing significant damage before security measures are adapted to new attacks. For example, blacklisting prevents communications with known malicious hosts, but many users may fall victim to an attack before blacklists are updated. In this dissertation we argue for a proactive approach to fighting cybercrime. Our approach relies on the observation that to avoid attribution and to stay up amidst take-down attempts, miscreants must provision their infrastructure differently than legitimate web sites. Thus, we propose to proactively identify malicious activity using unique characteristics of malicious web site provisioning. Specifically, using near real-time feeds of malicious web hosts, we investigate the extent to which miscreants use five specific provisioning practices. The first three are based on the Domain Name System (DNS), which translates host names to IP addresses. We first examine fast-flux, a practice where the association between name and address changes much more frequently than usual. We then investigate the use of DNS wildcards, which point many host names to a single address. Next, we examine the use of orphan DNS servers, which are DNS servers in non-existent domains. Then, we study the concentration of malicious activity in certain networks. Finally, we examine web redirects, which may appear to be links to legitimate web sites but in reality trick users into visiting malicious sites. We find that although good web sites sometimes make use of some of these techniques, malicious web sites are more likely to use them. Consequently, their presence can be used for proactive identification of malicious web sites.
Belmont Castle : the excavation of a Crusader stronghold in the kingdom of Jerusalem

This is the final definitive publication of the excavations that were conducted by the British School of Archaeology in Jerusalem on the site of the Crusader castle of Belmont (Suba), in the Judaean hills west of Jerusalem, between 1986 and 1989. The excavations and associated documentary research indicate that Belmont began its existence as a manor house or maison-forte in the first half of the twelfth century; at that time it probably represented the country seat of a fief-holding knight on the royal domain. By the 1140s, however, the area in which Belmont lay had been acquired by the Hospital of St John, which subsequently developed nearby Abu Ghosh (identified as biblical Emmaus) as the centre for an extensive estate. Following the Hospitallers takeover, while another former maison-forte, Aqua Bella, was converted into a priory or infirmary building, Belmont was extended and developed as a concentric castle, dominating the landscape round about. A polygonal outer ward was added to the original rectangular maison-forte on the top of the hill, and ranges of vaulted buildings were constructed within it. This castle fell to Saladin in 1187, and was slighted by the Ayyubids in 1191. After this, the site was occupied by a village until 1948. The account of the excavation is preceded by a historical introduction and a discussion of the castles archaeological setting. It is followed by specialist reports on the coins and tokens, pottery, ceramic lamps, Persian seal impressions, glass, metalwork, clay tobacco pipes, and objects of stone, bone and terracotta. A detailed analysis and discussion is provided of the faunal remains; and a concluding chapter discusses the castles architecture and planning, its military functions, and its economic role within an agricultural estate that developed in the later twelfth century to produce food and revenue for the Hospital in Jerusalem.
A TYPOLOGY OF URBAN DRIVING PATTERNS: A DESCRIPTIVE ANALYSIS AND ESTIMATION OF ENVIRONMENTAL EFFECTS

Driving patterns, such as speed and acceleration profiles, have a large effect on emissions and fuel consumption. This paper aims at creating a typology of urban driving patterns and applying it on data of speed, acceleration and engine speed profiles, etc. collected in real urban traffic. To obtain a typology of driving patterns cluster analysis was initially tested, but was, however, found to yield unstable results. Instead a typology was built based on exogenous segmentation of speed, occurrence of speed changes, acceleration and stopping occurrences. Fifteen segments were found to cover more that 98% of the total length, time driving and exhaust emitted. The driving pattern types were described in terms of speed, acceleration, deceleration, speed oscillation, percentage of stopping, RPA and engine speed. Their exhaust emission factors and fuel consumption factors were modeled and the contribution to the total amount of emission and fuel consumption within the city was calculated.
Failure Risk Factor For Non-Operative Treatment of Splenic Trauma

Background: Splenic trauma is a common pattern for admission in blunt abdominal trauma. The objective of this study is to identify risk factors for failure of non-operative management (NOM) in splenic trauma.Methods: This is a retrospective monocentric analysis of a prospectively collected database. All patients admitted in the university hospital of Nice [Centre Hospitalier Universitaire (CHU) de Nice, France] for a splenic trauma from January 1st 2006 to January 6th 2018 were included. Primary outcome was the need for delayed splenectomy as an indicator of NOM failure.Results: Two-hundred-eighty patients were included in this study. Most splenic lesions were severe grades (grade 3 or higher). In total, 83 splenectomies were performed urgently, i.e. 29% of patients; 88 angio-embolizations, i.e., 31% of patients with a success rate greater than 80%; 14.7% of 136 patients who had no previous angio-embolization required secondary splenectomy; 19.7% of the 61 patients who had anterior angio-embolization required secondary splenectomy. Age was not found associated with a higher failure rate (44 years in successful embolization vs 37.5 years in NOM-failure group, p = 0.15). Higher drop in hemoglobin levels between admission and 6 hours after admission was detected in the embolization failure group (-1.44 g/dl) as compared with the successful group (-0.68 g/dl), which approached statistical significance (p = 0.064). Conclusions: Hemoglobin monitoring in the hours following the admission of a patient with splenic trauma might be an important factor during the medical supervision of hemodynamically stable patients. Early identification of patients at high risk of NOM failure by hemoglobin monitoring may prevent late splenectomy.Level of evidence: IV (retrospective study)
Force reconstruction for impact tests of an energy-absorbing nose

Delivery of a bomb into hard targets at speeds of up to 120 fps required the design of an energy-absorbing nose. The purpose of the nose is to decelerate the projectile and, by absorbing the kinetic energy with deformation, protect the projectile's internal components from high-level (shock) decelerations. A structural simulation of the projectile was designed to test the dynamic deformation characteristics of the energy-absorbing nose. The simulated projectile was instrumented with eight accelerometers mounted with a shock isolation technique. The dynamic force as a function of nose deformation was the desired result from the impact tests because it provides the designer with a performance criterion for the nose design. The dynamic force was obtained by combining the accelerations using the Sum of Weighted Accelerations Technique (SWAT). Results from two field tests are presented. 12 refs., 8 figs.
Recent Technical Trends in Ball Screws

Ball screws were first utilized as part of automotive steering systems by G.M. in the U.S. in the late 1930’s. Twenty years later, the first ball screw was manufactured in Japan by NSK Ltd., and in 1961, NSK delivered its first precision ball screws for machine tools. Since then, as machine tools have become numerically controlled, ball screws have made great progress both in quality and production quantity. Applications for ball screws have been increasing due to their superiority over other linear motiontransmitting elements in terms of the balance between cost and performance, and their being widely recognized as easy to use and control. In the mechatronics field for semiconductors, LCDs and robots in particular, demand for ball screws has grown to nearly equal that for ball screws used in machine tools. Additionally, demand for ball screws for special environment applications such as in aircraft, outer space and nuclear reactors is rising sharply. Considering this rising demand and broadening range of applications together with users’ needs to continually improve their specific applications, the need for improved ball screw performance has no limit. In this article, recently developed technologies for increasing the operational speed of ball screws and satisfying the diversifying needs of today’s market are explained, and related new products are presented.
Data Science Applied to Carbon Materials: Synthesis, Characterization, and Applications

Data science has been rapidly developed and implemented in diverse scientific and technological fields over the past decade, to accelerate new knowledge generation and develop high‐impact applications. Recently, different data science tools and techniques have been widely used, such as optimizations, regressions, and classifications of data (tabular, spectral, or visual). In this review, data science tools and techniques are discussed for their adoption for the synthesis, characterization, and applications of carbon‐based materials. Materials synthesis in conjunction with data science has resulted in optimal growth conditions with desired properties and processing techniques. Regarding characterization, molecular structures can be reconstructed using microscopy images, and a particular property can be predicted based on the other properties of the desired carbon material. Moreover, for the applications of carbon materials, data science has enabled prediction of the water treatment efficiency, classification of electronic signals, prediction of the biological activity, and virus classification. It is clear that by combining data science and carbon‐related materials, it is now possible to accelerate theory‐experimental research in the quest for novel materials and their emerging applications.
Distributed deployment algorithms for mobile wireless sensor networks

Many visions of the future include people immersed in an environment surrounded by sensors and intelligent devices who use smart infrastructures to improve the quality of life and safety in emergency situations. Ubiquitous communication enables these sensors or intelligent devices to communicate with each other and to or with the user by means of ad-hoc wireless networking. Organization and optimization of network resources are essential to provide ubiquitous communication for a longer duration in large-scale networks and are helpful to migrate intelligence from higher and remote levels to lower and local levels. In this dissertation, we propose distributed energy-efficient deployment algorithms for mobile sensors and intelligent devices that form an intelligent wireless network. These algorithms employ a synergistic combination of cluster structuring and a peer-to-peer deployment scheme. An energy-efficient deployment algorithm based on Voronoi diagrams is also proposed here. Performance of our algorithms is evaluated in terms of coverage, uniformity, and time and distance traveled till the algorithm converges. Our algorithms are shown to exhibit excellent performance.

Benefits of Using Geotextile Between Subgrade Soil and Base Course Aggregate inLow-Volume Roads in Virginia

Geosynthetics have increasingly been used since the 1960s in pavement structures to provide reinforcement; to serve as a permeable separator to prevent mixing of subgrade with subbase or base course materials; and to provide drainage. A reliable method of quantifying these benefits is needed to justify the more widespread use of these materials. The purpose of this study was to quantify the benefit of using a geotextile as a separator in low-volume roadways such as secondary and subdivision streets. A field trial was conducted on a section of Virginia Route 743 near the Charlottesville-Albemarle Airport in Albemarle County to achieve this objective. A geotextile was placed between the aggregate base and subgrade in one lane of the section to prevent failure attributable to intermixing, and the adjacent lane was left unmodified as a control. In addition to the field trial, a small-scale accelerated loading laboratory test was conducted to quantify the benefit of using geotextile as a separator for a range of pavement design variables, including variations in soil strength, traffic volume, and aggregate properties. A statistical analysis of data gathered by a falling weight deflectometer during construction and after 8 months of traffic showed the lane with geotextile to have a slightly higher structural capacity. As severe intermixing and base failure in the control section were not expected during the 8-month period because of the low volume of traffic and a dry season, the benefit may have been attributable to a reinforcing effect. Although the size of the apparatus and the boundary condition may have prevented the most accurate quantification of the benefit, the laboratory testing further demonstrated the benefit. Most laboratory samples with geotextile had less deformation than the control sample. Intermixing of soil and aggregate was not observed when very densely graded base aggregate was used. When a more open-graded aggregate was used, the geotextile reduced the amount of fines migration into the aggregate layer; however, the fouled aggregate did not appear to have lost significant structural stiffness. Therefore, the separator benefit of geotextile in the laboratory testing was also apparently attributable to a reinforcing effect. The use of geotextile materials appears to have great potential to extend the service life of pavements on the secondary road system, offering significant cost savings to the Virginia Department of Transportation. It is recommended that this section of road be periodically evaluated to quantify this potential increased service and that more test sections on subdivision streets with a weaker subgrade condition or full-scale accelerated testing be conducted for a reliable quantification of the benefit.
Radio Frequency Circuits for Tunable Multi-Band CMOS Receivers for Wireless LAN Applications

Abstract : Currently, three mainstream wireless LAN (WLAN) standards, IEEE 802.11a, b and g, co-exist in the market. The network should be able to work with all these standards. This has increased the demand of multi-band wireless LAN transceivers. Being a commercial application, the transceiver must be low cost, which points to a CMOS single chip solution. This dissertation addresses the design issues of multi-band CMOS WLAN receivers. A multi-band and multi-function receiver architecture is proposed for wireless LAN applications. The key blocks include RF switches, a multi-band RF down-converter, a multi-band voltage controlled oscillator (VCO) and a wide-tuning range VCO. This thesis work demonstrates the feasibility of realizing these circuits in CMOS technology. Two RF CMOS switches working at 2.4 GHz and 5.8 GHz were designed and tested. The 2.4-GHz switch exhibits sufficient performance for 802.11b/g applications.
Synthesis of Carboxymethyl Chitosan-Capped Gold Nanoparticles by Gamma Irradiation with Novel Potential Applications as Antioxidant, Hepatoprotective, and Anticancer Substance

Gold nanoparticles capped by carboxymethyl chitosan (AuNPs/CM-chitosan) with particle sizes of 5.2–7.3 nm were successfully synthesized by the γ-irradiation of Au3+ solutions. Their characteristics were analysed by transmission electron microscope images, powder X-ray diffraction patterns, UV-visible spectroscopy, and Fourier transform infrared spectra. The antioxidant activity of AuNP/CM-chitosan was time dependent and much higher than that of ascorbic acid at the same concentration. On the other hand, the results of tail vein injection of AuNP/CM-chitosan in mice indicated that this product was not toxic to mice and that AuNPs were mainly distributed in liver tissue, at approximately 77.5%, 6 h after injection. The hepatoprotective activity of AuNP/CM-chitosan was also tested in acetaminophen-induced hepatotoxic mice by oral administration at daily doses of 0.5–2 mg/head. The results indicated that compared to the control, supplementation with 2 mg of AuNPs/head strongly reduced the aspartate aminotransferase and alanine aminotransferase indexes in the blood of the tested mice by approximately 66.5 and 69.3%, respectively. Furthermore, the MTT (3[4,5 dimetylthiazol-2-yl]-2,5-diphenyltetrazol bromide) assay on a liver cancer cell line (HepG2) clearly confirmed strong anticancer activity on HepG2 cells treated with 0.05–0.5 mM AuNPs and the tested cells did not survive after treatment with 0.5 mM AuNPs, while the growth of the normal cell line (L929) has no significant effect at the same treated concentration of AuNPs. The AuNP/CM-chitosan in the present study was synthesized by the γ-irradiation method without using any toxic-reducing chemical and stabilized in a natural biocompatible polymer. The strong antioxidant, hepatoprotective, and anticancer effects of this product may be supported to be used in the biomedical field.
The Power Elite

First published in 1956, The Power Elite stands as a contemporary classic of social science and social criticism. C. Wright Mills examines and critiques the organization of power in the United States, calling attention to three firmly interlocked prongs of power: the military, corporate, and political elite. The Power Elite can be read as a good account of what was taking place in America at the time it was written, but its underlying question of whether America is as democratic in practice as it is in theory continues to matter very much today. What The Power Elite informed readers of in 1956 was how much the organization of power in America had changed during their lifetimes, and Alan Wolfe's astute afterword to this new edition brings us up to date, illustrating how much more has changed since then. Wolfe sorts out what is helpful in Mills book and which of his predictions have not come to bear, laying out the radical changes in American capitalism, from intense global competition and the collapse of communism to rapid technological transformations and ever changing consumer tastes. The Power Elite has stimulated generations of readers to think about the kind of society they have and the kind of society they might want, and deserves to be read by every new generation.
