Citizen Wayn? The Struggle of Parliament in Contemporary Jordan

This article is part of the Special Issue “Parliaments in the Middle East and North Africa: A Struggle for Relevance”. Because the politics of citizenship is felt at all stages of the parliamentary process, the very question of parliamentary relevance itself cannot be answered without reference to the citizenry. That Jordan’s citizenship regime influences and impedes parliamentary politics is explored through two cases. The first being decentralization, understood as a relocating of tasks, decision-making and mandates from a centralized location to different, more localized levels. The second study focuses on the uprisings occurring from May 30, 2018 against the draft domestic tax law introduced to parliament by the government of then-Prime Minister Hani al-Mulki. Both cases are implicated in the Kingdom’s parliamentary politics, and their selection is a conscious move away from election analysis. Taken together they elucidate how citizenship is a key battleground on which any future emancipation/development of parliament will be fought.

Influence of Landscape Factors and Abiotic Conditions on Dispersal Behavior and Overwintering Site Selection by Halyomorpha halys (Hemiptera: Pentatomidae)

Since the initial detection of the invasive Halyomorpha halys (Stål) in the United States in the late 1990s, this insect has emerged as a severe agricultural and nuisance pest. Nuisance problems are due to adult dispersal to overwintering sites in the fall at which time they alight onto and eventually settle within human-made structures in addition to natural harborage. This study examined how three factors, elevation, light, and moisture affected overwintering site selection by H. halys in the mid-Atlantic. Observational counts performed along elevational transects revealed elevation was significant predictor of H. halys abundance during both years of the study in 2014 and 2015 with more adults observed at higher elevations. Choice tests examining effects of moisture and light on settling behavior demonstrated H. halys settled within overwintering shelter boxes in significantly greater numbers when shelters were dry compared with those having moist conditions, and in darkened shelters compared with those augmented with LED lights. Our findings indicate that H. halys use cues at both landscape and very localized levels when seeking and selecting overwintering sites.

HfS2 and TiS2 Monolayers with Adsorbed C, N, P Atoms: A First Principles Study

First principles density functional theory was used to study the energetic, structural, and electronic properties of HfS 2 and TiS 2 materials in their bulk, pristine monolayer, as well as in the monolayer structure with the adsorbed C, N, and P atoms. It is shown that the HfS 2 monolayer remains a semiconductor while TiS 2 changes from semiconductor to metallic behavior after the atomic adsorption. The interaction with the external atoms introduces localized levels inside the band gap of the pristine monolayers, significantly altering their electronic properties, with important consequences on the practical use of these materials in real devices. These results emphasize the importance of considering the interaction of these 2D materials with common external atomic or molecular species.

"It's Not Being Racist, but ... "

This article explores the tacit endorsement of male youth gang members engaging in “race”-based conflict to gain localized levels of power. It examines the importance of belonging to an “in-group” for these young people via their connectedness to the broader residents, through cultural essentialism toward a Roma “out-group.” The young, male gang members, drawing on what they perceive to be their role, adopt physical and symbolic strategies to assert their control over their space and to concretize their sense of belonging with the wider community in-group. The article considers how a labeled and excluded group of male youth gang members from wider social structures find connection, commonality, and belonging in hardening their self-image through an othering process against those deemed inferior to them.

The Systems of Volume-Localized Electron Quantum Levels of Charged Fullerenes

The existence of a system of short-lived, discrete, volume-localized electron quantum levels in positively charged fullerenes is theoretically and numerically demonstrated using the example of fullerenes C60 and C20. Unlike experimentally and theoretically well-studied electron states localized in a thin surface layer, these electron states are due to the flat part of the Coulomb potential of a positively charged fullerene sphere. The energy width of the system of such discrete volume-localized levels depends on the charge and increases with increasing charge. For C60+1, the energy width is 0.16 a.u. and increases up to 0.9 a.u. for fullerene C60+10. Thus, the electrons captured on these discrete levels of fullerene form a sort of short-lived superheavy “nanoatom” or “nanoion,” in which the electrons are localized inside a positively charged spherical “nucleus” with an atomic mass of 240 a.u. for C20 and 720 a.u. for C60. Numerous published papers have demonstrated theoretically and experimentally the existence of metastable positively charged C60 fullerenes with a charge of +10 or more, which suggests the possibility of experimental observation of the considering system of volume-localized electronic states. In conclusion, questions are discussed and estimates are made of the possibility of generating coherent radiation at these transitions.

Atmosphere-Dependent Photoconductivity of ZnO in the Urbach Tail

Photoconductivity is a fundamental and highly applicable phenomenon for semiconductor oxide-based devices, and the presence of defects plays a significant role in this mechanism. Here, we present an investigation based on different atmospheres and light excitation (above and below bandgap) dependences of zinc oxide thin film grown by spray-pyrolysis. As-grown ZnO presents a representative Urbach tail associated to the presence of localized levels in the bandgap. Photoconductivity response and decay times are investigated for air and inert atmospheres as well as under vacuum conditions with significant features due to light excitation conditions. The observed characteristics are explained based on oxygen photodesorption when excitation is above bandgap while this process is suppressed when excitation is below bandgap.

Dentistry and Childhood Poverty in the United States

The proportion and numbers of children living in low income families and without health insurance continues to increase. The magnitude of these problems is considered at localized levels in terms of the impact on the use of dental services.

Nitrogen Related Deep Levels in GaAsN Films Investigated by a Temperature Dependence of Piezoelectric Photothermal Signal

The temperature dependences of the piezoelectric photo-thermal (PPT) signals from unintentionally doped p-type GaAsN films grown on semi-insulating GaAs substrate were measured from 80 to 300 K. From the theoretical analysis based on the rate equation for the recombination of photo exited carriers to the localized levels, we identified five majority hole traps, P1-P5 in GaAsN films. Among them, estimated concentrations of the P3 and P5 traps increased with the nitrogen contents. Therefore, we concluded that these two traps were due to nitrogen-related recombination centers in GaAsN.
