Borrowing Privilege: Status Maneuvering among Marginalized Men

Research shows people confront social marginalization through work, yet this scholarship largely ignores people working in illicit markets. We address this gap by investigating how and to what end men in street prostitution “borrow” privilege from their more structurally advantaged clients. Drawing from interviews with men of color in street sex work, we show how they “status maneuver” to offset stigmatized identities tied to prostitution and to construct a masculinity that offers a greater sense of social worth within constrained circumstances. These men ironically rely on status differences between themselves and their white, wealthy men clients to undermine their own oppression and to create possibilities for momentary associations with hegemonic masculine privilege. This research shows how barriers between the powerful and powerless are permeable, and how social hierarchies serve as resources to cope with the inequitable conditions and stigma under which some people live and work.
Population dynamics of the venerid bivalve Tawera gayi (Hupe´ , 1854) in the Ushuaia Bay, Beagle Channel

Summary Growth, productivity and potential for exploitation of the clam Tawera gayi from shallow waters (3–5 m) of Ushuaia Bay, Beagle Channel were investigated. Mean abundance and biomass in the study area were 1091 ± 737 ind. m )2 and 901.83 g SFWM m )2 (shell-free wet mass), respectively. Individual growth was described best by the von Bertalanffy growth model with the parameter values H¥ ¼ 28.03 mm, K ¼ 0.288 year )1 , t0 ¼ )0.34 (r 2 ¼ 0.83). Annual production of the population was estimated to be 120.45 g SFWM m )2 year )1 , corresponding to a production-to-biomass ratio (P/B) of 0.134 year )1 . The single negative exponential mortality model does not fit the population mortality pattern, but predation by gastropods (Xymenopsis muriciformis, Trophon geversianus, Natica sp.) appears to be the major cause of mortality. These highly mobile predators together with the comparatively slow growth and low turnover of T. gayi in Ushuaia Bay limit its potential for sustainable commercial exploitation.
Polypropylene/Graphene and Polypropylene/Carbon Fiber Conductive Composites: Mechanical, Crystallization and Electromagnetic Properties

This study aims to examine the properties of composites that different carbon materials with different measurements can reinforce. Using a melt compounding method, this study combines polypropylene (PP) and graphene nano-sheets (GNs) or carbon fiber (CF) to make PP/GNs and PP/CF conductive composites, respectively. The DSC results and optical microscopic observation show that both GNs and CF enable PP to crystalize at a high temperature. The tensile modulus of PP/GNs and PP/CF conductive composites remarkably increases as a result of the increasing content of conductive fillers. The tensile strength of the PP/GNs conductive composites is inversely proportional to the loading level of GNs. Containing 20 wt% of GNs, the PP/GNs conductive composites have an optimal conductivity of 0.36 S/m and an optimal EMI SE of 13 dB. PP/CF conductive composites have an optimal conductivity of 10−6 S/m when composed of no less than 3 wt% of CF, and an optimal EMI SE of 25 dB when composed of 20 wt% of CF.
Fast Fourier Transform computations and build-up of plastic deformation in 2D, elastic-perfectly plastic, pixelwise disordered porous media

Stress and strain fields in a two-dimensional pixelwise disordered system are computed by a Fast Fourier Transform method. The system, a model for a ductile damaged medium, consists of an elastic-perfectly matrix containing void pixels. Its behavior is investigated under equibiaxial or shear loading. We monitor the evolution with loading of plastically deformed zones, and we exhibit a nucleation / growth / coalescence scenario of the latter. Identification of plastic ``clusters'' is eased by using a discrete Green function implementing equilibrium and continuity at the level of one pixel. Observed morphological regimes are put into correspondence with some features of the macroscopic stress / strain curves.
A New Method for Decision Making and Planning in Enterprises

In the process of enterprise architecture planning, the As-Is architecture is considered as a baseline architecture, and target-architecture is designed on its basis. The use of enterprise architecture maturity is one of the methods of enterprise architecture development and improvement. But in some occasions, enterprise architecture cannot play an efficient role in baseline architecture and making decisions. In this research we present a systematic process to exactly create as-is architecture. Then we represent a method for assessment and measurement of the potency of As-Is architecture. Another advantage of this method is the possibility of using the scores resulted in CBA1 that we can use in nonprofit organizations. Based on the importance of each item, there is possibility for decision making for planning and scheduling of activities for development of enterprises and select a subset of them. In order to validate the proposed method, a software tool was also developed and two different case studies were performed.
Private-key Symbolic Encryption Schemes

Symbolic encryption, in the style of Dolev-Yao models, is ubiquitous in formal security analysis aiming at the automated verification of network protocols. The näıve use of symbolic encryption, however, may unnecessarily require an expensive construction: an arbitrary-length encryption scheme that is private and non-malleable in an adaptive CCACPA setting. Most of the time, such assumptions remain hidden and rather symbolic encryption is instantiated with a seemingly “good” cryptographic encryption, such as AES in the CBC configuration. As an illustration of this problem, we first report new attacks on ECB and CBC based implementations of the well-known Needham-Schroeder and Denning-Sacco protocols. We then present a few symbolic encryption schemes along with their cryptographic semantics, and prove the hierarchical relations between the proposed schemes from both cryptographic and formal perspectives. These symbolic schemes can be seamlessly used in many existing formal security models.
A Compact Low Power High Frequency Pulse Generator

This paper proposes a compact, low power high frequency trigger pulse generator circuit. Delay-introducing circuit that can incorporate a certain amount of delay during signal processing while maintaining the signal integrity is utilized in the proposed design. This paper evaluates performance of various delay-introducing circuits in terms of different design matrices. Further, this paper exploits the low power consuming delay element to implement the proposed trigger pulse generator. The proposed design generates very high frequency pulses at the cost of negligible power consumption. The effectiveness of the proposed circuit is presented by producing ultra-thin pulses of pulse duration 92.35 ps while consuming power of only 1.502 μW. Extensive simulations are carried out on SPICE @ 16-nm predictive technology model to verify the proposed design.
Timelike Hopf duality and type IIA* string solutions

The usual T-duality that relates the type IIA and IIB theories compactified on circles of inversely related radii does not operate if the dimensional reduction is performed on the time direction rather than a spatial one. This observation led to the recent proposal that there might exist two further ten-dimensional theories, namely type IIA and IIB, related to type IIB and IIA, respectively, by a timelike dimensional reduction. In this paper we explore such dimensional reductions in cases where time is the coordinate of a non-trivial U. 1/ fibre bundle. We focus, in particular, on situations where there is an odd-dimensional anti-de Sitter spacetime AdS 2n+1, which can be described as aU. 1/bundle overg n , a non-compact version ofCP n corresponding to the coset manifold SU.n; 1/=U.n/. In particular, we study the AdS5 S 5 and AdS7 S 4 solutions of type IIB supergravity and 11-dimensional supergravity. Applying a timelike Hopf T-duality transformation to the former provides a new solution of the type IIA theory, of the form g 2 S 1 S 5 . We show how the Hopf-reduced solutions provide further examples of 'supersymmetry without supersymmetry'. We also present a detailed discussion of the geometrical structure of the Hopf-fibred metric on AdS 2n+1, and its relation to the horospherical metric that arises in the AdS/CFT correspondence.
Higher Education and Political Attitude Change: Is Israel the Exception that Proves the Rule?

Israel presents a critical test of the well-established finding from other nations that higher education strongly influences the political attitudes of young people. Most Israelis attend university only after completing military service and are thus exposed to a powerful socializing institution before beginning higher education. This sequence may pre-empt the influence of university experience by socializing IDF members to durable political attitudes while they are serving. By means of a survey of Israeli university students who entered higher education after military service, we test whether exposure to higher education changes attitudes to Israeli Arabs and the Israeli-Arab conflict.
ASCA observations of deep ROSAT fields — II. The 2–10 keV AGN luminosity function

We present additional optical spectroscopic identifications of sources identified in three deep ASCA GIS fields which also form part of a deep ROSAT survey. In total, 26 ASCA sources have been detected down to a 2–10 keV flux limit of S2−10 = 5 × 10−14 erg cm−2 s−1. Low Dispersion Survey Spectrograph observations have increased the spectroscopic completeness of the survey to between 65 and 85 per cent, with identifications for up to 13 QSOs with broad emission lines and six objects with narrow emission lines. Combining these objects with the AGN identified in the HEAO A-1 sample by Grossan, we find evidence for significant cosmological evolution in the 2–10 keV band (〈Ve/Va〉 = 0.63 ± 0.03), fitted by a pure luminosity evolution model: L ∝ (1 + z)k, k = 2.04+0.18−0.22. The present-epoch 2–10 keV AGN X-ray luminosity function, Φ(LX), is best represented by a two-power-law function: Φ(LX) ∝ L−3.0, L* > 1044.1 erg s−1; Φ(LX ∝ L−1.9, L* 1042 erg s−1) to 80 per cent (LX > 1039 erg s−1).
Essays on schooling, occupations, and earnings

This thesis consists of two chapters. The first chapter investigates the causes of the recent slowdown in college attainment in the United States. The second chapter studies the gender wage gap by occupational complexity. For white males born in the United States after 1950, there is a stagnation in the fraction of high school graduates that go on to complete a four-year college degree. At the same time, across successive cohorts, those with a four year-college degree achieve increasingly higher lifetime earnings than those with a high school degree. What caused this phenomenon? I formulate a life-cycle model of human capital accumulation in college and on the job, where successive cohorts decide whether or not to acquire a college degree as well as the quality of their college education. Cohorts differ by the sequence of rental price per unit of human capital they face. My model reproduces the observed pattern in college attainment for the 1920 to 1970 birth cohorts. The stagnation in college attainment is due to the decrease in the growth rate of the rental price per unit of human capital commencing in the 1970s. My model also generates 79% of the increase in earnings for college graduates relative to those for high school graduates. Part of this increase is reinforced by a stronger association between college and ability. Female to male wages are U-shaped across occupations ordered by increasing complexity, where complexity is defined as the ratio of abstract to manual tasks content. The U-shape flattens over the lifecycle and across successive cohorts. I
Optical Studies of 20 Longer-Period Cataclysmic Binaries

We obtained time-series radial-velocity spectroscopy of 20 cataclysmic variable stars, with the aim of determining orbital periods Porb. All of the stars reported here prove to have Porb > 3.5 h. For 16 of the stars, these are the first available period determinations, and for the remaining four (V709 Cas, AF Cam, V1062 Tau, and RX J2133 + 51), we use new observations to improve the accuracy of previously published periods. Most of the targets are dwarf novae, without notable idiosyncrasies. Of the remainder, three (V709 Cas, V1062 Tau, and RX J2133 + 51) are intermediate polars (DQ Her stars); one (IPHAS 0345) is a secondary-dominated system without known outbursts, similar to LY UMa; one (V1059 Sgr) is an old nova; and two others (V478 Her and V1082 Sgr) are long-period novalike variables. The stars with new periods are IPHAS 0345 (0.314 days); V344 Ori (0.234 days); VZ Sex (0.149 days); NSVS 1057 + 09 (0.376 days); V478 Her (0.629 days); V1059 Sgr (0.286 days); V1082 Sgr (0.868 days); FO Aql (0.217 days); V587 Lyr (0.275 days); V792 Cyg (0.297 days); V795 Cyg (0.181 days); V811 Cyg (0.157 days); V542 Cyg (0.182 days); PQ Aql (0.247 days); V516 Cyg (0.171 days); and VZ Aqr (0.161 days). Noteworthy results on individual stars are as follows. We see no indication of the underlying white dwarf star in V709 Cas, as has been previously claimed; based on the nondetection of the secondary star, we argue that the system is farther away that had been thought and the white dwarf contribution is probably negligible. V478 Her had been classified as an SU UMa-type dwarf nova, but this is incompatible with the long orbital period we find. We report the first secondary-star velocity curve for V1062 Tau. In V542 Cyg, we find a late-type contribution that remains stationary in radial velocity, yet the system is unresolved in a direct image, suggesting that it is a hierarchical triple system.
Commitment to Social Good and Insider Trading

A firm׳s investment in corporate social responsibility (CSR) builds a positive image of caring for social good and imposes additional costs on executives׳ informed trading, which is widely perceived self-serving. We thus expect executives of CSR-conscious firms to be more likely to refrain from informed trading. We find that executives of CSR-conscious firms profit significantly less from insider trades and are less likely to trade prior to future news than executives of non-CSR-conscious firms. The negative association between CSR and insider trading profits is more pronounced when executives׳ personal interests are more aligned with the interests of the firm.
Understanding Mathematical Discourse

Discourse Understanding is hard. This seems to be especiall y true for mathematical discourse, that is proofs. Restricting discourse to mathemati cal discourse allow us, however, to study the subject matter in its purest form. This domain of discourse is rich and welldefined, highly structured, offers a well-defined set of disc ourse relations and forces/allows us to apply mathematical reasoning. We give a brief discussionon selected linguistic phenomena of mathematical discourse, and an analysis from the mathematician’s point of view. Requ ir ments for a theory of discourse representation are given, followed by a discussi on of proofs plans that provide necessary context and structure. A large part of semantics c on truction is defined in terms of proof plan recognition and instantiation by matching and ttaching.
Families of periodic horseshoe orbits in the restricted three-body problem

We compute families of symmetric periodic horseshoe orbits in the restricted three-body problem. Both the planar and three-dimensional cases are considered and several families are found. We describe how these families are organized as well as the behavior along and among the families of parameters such as the Jacobi constant or the eccentricity. We also determine the stability properties of individual orbits along the families. Interestingly, we find stable horseshoe-shaped orbit up to the quite high inclination of 17 ◦ .
An Insight into the Changes in Human Plasma Proteome on Adaptation to Hypobaric Hypoxia

Adaptation to hypobaric hypoxia is required by animals and human in several physiological and pathological situations. Hypobaric hypoxia is a pathophysiological condition triggering redox status disturbances of cell organization leading, via oxidative stress, to proteins, lipids, and DNA damage. Identifying the molecular variables playing key roles in this process would be of paramount importance to shed light on the mechanisms known to counteract the negative effects of oxygen lack. To obtain a molecular signature, changes in the plasma proteome were studied by using proteomic approach. To enrich the low-abundance proteins in human plasma, two highly abundant proteins, albumin and IgG, were first removed. By comparing the plasma proteins of high altitude natives with those of a normal control group, several proteins with a significant alteration were found. The up-regulated proteins were identified as vitamin D-binding protein, hemopexin, alpha-1–antitrypsin, haptoglobin β-chain, apolipoprotein A1, transthyretin and hemoglobin beta chain. The down-regulated proteins were transferrin, complement C3, serum amyloid, complement component 4A and plasma retinol binding protein. Among these proteins, the alterations of transthyretin and transferrin were further confirmed by ELISA and Western blotting analysis. Since all the up- and down- regulated proteins identified above are well-known inflammation inhibitors and play a positive anti-inflammatory role, these results show that there is some adaptive mechanism that sustains the inflammation balance in high altitude natives exposed to hypobaric hypoxia.

Genome-Wide Dynamic Transcriptional Profiling of the Light-to-Dark Transition in Synechocystis sp. Strain PCC 6803

ABSTRACT We report the results of whole-genome transcriptional profiling of the light-to-dark transition with the model photosynthetic prokaryote Synechocystis sp. strain PCC 6803 (Synechocystis). Experiments were conducted by growing Synechocystis cultures to mid-exponential phase and then exposing them to two cycles of light/dark conditions, during which RNA samples were obtained. These samples were probed with a full-genome DNA microarray (3,169 genes, 20 samples) as well as a partial-genome microarray (88 genes, 29 samples). We concluded that (i) 30-min sampling intervals accurately captured transcriptional dynamics throughout the light/dark transition, (ii) 25% of the Synechocystis genes (783 genes) responded positively to the presence of light, and (iii) the response dynamics varied greatly for individual genes, with a delay of up to 120 to 150 min for some genes. Four classes of genes were identified on the basis of their dynamic gene expression profiles: class I (108 genes, 30-min response time), class II (279 genes, 60 to 90 min), class III (258 genes, 120 to 150 min), and class IV (138 genes, 180 min). The dynamics of several transcripts from genes involved in photosynthesis and primary energy generation are discussed. Finally, we applied Fisher discriminant analysis to better visualize the progression of the overall transcriptional program throughout the light/dark transition and to determine those genes most indicative of the lighting conditions during growth.
Hormonal Regulation of Response to Oxidative Stress in Insects—An Update

Insects, like other organisms, must deal with a wide variety of potentially challenging environmental factors during the course of their life. An important example of such a challenge is the phenomenon of oxidative stress. This review summarizes the current knowledge on the role of adipokinetic hormones (AKH) as principal stress responsive hormones in insects involved in activation of anti-oxidative stress response pathways. Emphasis is placed on an analysis of oxidative stress experimentally induced by various stressors and monitored by suitable biomarkers, and on detailed characterization of AKH’s role in the anti-stress reactions. These reactions are characterized by a significant increase of AKH levels in the insect body, and by effective reversal of the markers—disturbed by the stressors—after co-application of the stressor with AKH. A plausible mechanism of AKH action in the anti-oxidative stress response is discussed as well: this probably involves simultaneous employment of both protein kinase C and cyclic adenosine 3′,5′-monophosphate pathways in the presence of extra and intra-cellular Ca2+ stores, with the possible involvement of the FoxO transcription factors. The role of other insect hormones in the anti-oxidative defense reactions is also discussed.
Estimation of Technical Efficiency for Rice Farms in Central Thailand Using Stochastic Frontier Approach

As one of Thailand's economic crops, rice plays an important role in generating national income and creating domestic employment for the country. Its production has been increasing because of the expansion of areas planted to rice and not due to increases in productivity. The national average yield is considerably low compared with that of other rice-producing countries. This study measured the technical efficiency of rice farmers in the central region of Thailand and identified the factors causing technical inefficiency using stochastic frontier analysis (SFA) approach specified as a translog production function. Cross-sectional data were randomly collected from 384 sampled farmers from nine provinces of central Thailand who generally operated their farms using pre-germinated broadcasting method in the major rice crop year 2009/2010. Results reveal that technical efficiency ranged from 49.69 to 97.17 percent, with a mean of 85.35 percent. Gender, farming experience, good agricultural practices (GAP), and cropping intensity were found to contribute positively toward farm technical efficiency. Farmers should be provided knowledge of GAP and should adopt GAP in their farms' activities. Agricultural extension officers should organize knowledge and experience exchange between successful farmers and other farmers, and promote the use of certified seeds to improve farm efficiency and farmers' income.
