Supermaxes across the United States detain thousands in long-term solitary confinement, under conditions of extreme sensory deprivation. Almost every state built a supermax between the late 1980s and the late 1990s. This chapter examines the role of federal prisoners’ rights litigation in the 1960s and 1970s in shaping the prisons, especially supermaxes, built in the 1980s and 1990s in the United States. This chapter uses a systematic analysis of federal court case law, as well as archival research and oral history interviews with key informants, including lawyers, experts, and correctional administrators, to explore the relationship between federal court litigation and prison building and designing. This chapter argues that federal conditions of confinement litigation in the 1960s and 1970s (1) had a direct role in shaping the supermax institutions built in the subsequent decades and (2) contributed to the resistance of these institutions to constitutional challenges. The history of litigation around supermaxes is an important and as-yet-unexplored aspect of the development of Eighth Amendment jurisprudence in the United States over the last half century.

Research to find new energy source is still an intensive work by researchers in this field. One of the energy sources with no negative impact to environment is solar energy. Solar cell is used to convert solar energy to electrical energy. The electrically powered solar cell in direct current (DC) power is not suitable for our daily office equipment since they need the alternating current (AC) power. This research has succeeded in realizing a solar cell automation tool based on Arduino Uno with input from solar energy, from which output AC voltage can be used for the needs of household appliances and office equipments. Output power of this tool is approximately 700 W, which can turn on the lights, charge the hand phones, laptops, and so forth.

This chapter studies the large sample properties of a subclassification-based estimator of the dose–response function under ignorability. Employing standard regularity conditions, it is shown that the estimator is root-n consistent, asymptotically linear, and semiparametric efficient in large samples. A consistent estimator of the standard-error is also developed under the same assumptions. In a Monte Carlo experiment, we investigate the finite sample performance of this simple and intuitive estimator and compare it to others commonly employed in the literature.

Purpose – The objective of the present study was to determine the effect of monosodium glutamate (MSG) administration to pyramidal cells necrosis on the cerebral cortex of Wistar male rats (Rattus norvegicus).

Design/Methodology/Approach – This research was a laboratory quasi-experiment study with post-test control group design on 24 male Wistar rats (Rattus norvegicus) aged 8-10 weeks, weighted 200 ± 10 gr, divided into 4 groups (GI or control group, GII treated with MSG dose 6 mg/grbb/day, GIII 12 mg/grbb/day, and GIV 24 mg/grbb/day) for 21 days consecutively. Pyramidal cells observed in 10 field of view. The Kruskal-Wallis test and Mann Whitney tests were used to analyze the data.

Findings – There were significant differences between pyramidal cells necrosis numbers between control and the treatment groups. MSG doses 6, 12, and 24 mg/grbb/day developed the pyramidal cells necrosis in the cerebral cortex (p < 0,005).

Increasing growth in car ownership and private car usage is leading to high levels of congestion and pollution in many busy towns and cities. A reliable and efficient public transport service is one of the solutions for future transport provision. The development of a novel cell-based Automatic Vehicle Locationing system for public transport application is presented in this paper. The technique uses the existing AVL system and combines it with cellular technologies. Little modification is required to turn the existing AVL sequential polling system to the simultaneous cell-based AVL polling system. The fundamental advantage of the cell-based approach to AVL is that direct communication between the vehicles and the cell-based station enables the vehicle fleet to be polled simultaneously. Cell-based AVL System offers possibility for improved public transport service and public transport priority through frequent update of vehicle position and vehicle information. Modelling of cell-based AVL systems using a simulation method is given in this paper. The results show that the polling time for a bus fleet using the cell-based technique is considerably lower than the conventional sequential polling AVL system.

This study examines the relations among management control systems (MCS), environmental uncertainty (EU), and organizational slack (OS). Given a firm's EU, managing OS requires the support of an appropriately designed MCS. Thus, for different levels of OS and EU, we examine two forms of MCS: budgetary control and performance measurement system encompassing both financial and nonfinancial measures. EU and OS were determined using archival data, and MCS data was obtained via a survey questionnaire to chief executive officers (CEOs). As hypothesized, the results show that, given firms’ EU, the two forms of control play distinct but different roles in managing OS.

Natural selection is the mechanism of evolution originally proposed by Charles Darwin. This process is driven by mutation and death. Therefore, “individual death” is a critical event for evolution of species. Analogous to the significance of individual death in species evolution, recent biological observations have revealed that “cell death” is an important event for maintenance of individuals and offspring. Cell death is caused not only by injuries and pathological conditions, but also by programed intracellular signals. This type of programed cell death is called “apoptosis.” Apoptosis signals are regulated in mitochondria, eukaryotic organelles of symbiotic origin, and play a critical role in survival of individuals by eliminating some cells.

The adoption of mobile technology by the youth has been gaining momentum as a growing area of exploration for scholars. Several aspects of this technology, including its adoption and usage patterns, have been explored both theoretically and in empirical research. The purpose of this paper is to understand the cell phone usage of the young university students, the effects of this usage of the cell phone on their personal communication needs, their perceptions of cell phone communication in the society, and gender similarities and differences in these matters.

This paper relies on primary data of randomly selected engineering students in a university in South Africa. Data was collected from 200 respondents using face-to-face interviews with the help of a structured interview schedule.

The analysis shows the relationship between the measures of cell phone usage, personal communication, and perceptions, across different racial groups. The findings of the study have relevance and significance for the understanding of the communication patterns and their social consequences for the youth in South Africa.

Most of the research in this area has originated from the developed regions and countries in the Nordic region and Japan. This paper presents the findings on the cell phone use of students in South Africa.
