The Good Temp

[Excerpt] The story of the explosion of temporary employment and the challenge to the permanent employment contract in the last half of the twentieth century has been told many times. Researchers from\u27\u27a variety of academic disciplines have written about it, as have activists who organize to help American workers maintain a decent standard of living and a modicum of dignity, and policy analysts who fear the degradation of the employment relationship that seems to be a foregone implication of temporary work. They have focused on different units of analysis: workers who desire permanent jobs but can\u27t find them, workers who have lost out as companies have downsized and restructured, businesses and their myriad reasons for using temporary workers as a solution to their profitability and competition problems, and the temporary help service industry (THS) itself. The Good Temp takes a different tack to explain these developments in labor market institutions and behaviors. Specifically, we look at how the THS industry in the United States reinvented temporary work in the second half of the twentieth century and examine how individual THS agencies continue to manufacture and market this reinvented product—the good temporary worker—today. It is a customized, historically specific make and model whose marketability rested on two selling points: that temporary employment could be a viable alternative to permanent employment and that the workers on whom the system of temporary employment relations depends could be as good as permanent workers and sometimes better. The historical and social construction of the good temp, we show, was embedded in THS-industry profitmaking strategies and relied on the diffusion of new norms about what constituted acceptable employment practice. Now entrenched, these norms underpin our current employment relations in the United States which many, if not most, of us experience as precarious and contingent, even when we have so-called permanent jobs

The diameter of the set of boundary slopes of a knot

Let K be a tame knot with irreducible exterior M(K) in a closed, connected, orientable 3--manifold Sigma such that pi_1(Sigma) is cyclic. If infinity is not a strict boundary slope, then the diameter of the set of strict boundary slopes of K, denoted d_K, is a numerical invariant of K. We show that either (i) d_K >= 2 or (ii) K is a generalized iterated torus knot. The proof combines results from Culler and Shalen [Comment. Math. Helv. 74 (1999) 530-547] with a result about the effect of cabling on boundary slopes.Comment: This is the version published by Algebraic & Geometric Topology on 29 August 200

Electroweak superpartner production at 13.6 TeV with Resummino

Due to the greater experimental precision expected from the currently ongoing LHC Run 3, equally accurate theoretical predictions are essential. We update the documentation of the Resummino package, a program dedicated to precision cross section calculations for the production of a pair of sleptons, electroweakinos, and leptons in the presence of extra gauge bosons, and for the production of an associated electroweakino-squark or electroweakino-gluino pair. We detail different additions that have been released since the initial version of the program a decade ago, and then use the code to investigate the impact of threshold resummation corrections at the next-to-next-to-leading-logarithmic accuracy. As an illustration of the code we consider the production of pairs of electroweakinos and sleptons at the LHC for centre-of-mass energies ranging up to 13.6 TeV and in simplified model scenarios. We find slightly increased total cross section values, accompanied by a significant decrease of the associated theoretical uncertainties. Furthermore, we explore the dependence of the results on the squark masses.Comment: 30 pages, 5 figure

The perceptions of social responsibility for community resilience to flooding: the impact of past experience, age, gender and ethnicity

Community resilience to flooding depends, to a large extent, on the participation of community members to take more responsibility for enhancing their own resilience. The perception of social responsibility (SR) which is argued to be one of the antecedents influencing individual’s willingness to undertake resilient behaviours can significantly contribute to community resilience through individual and collective actions. Understanding of factors influencing the perceptions of SR of individuals within community might help with developing strategies to increase the perceptions of SR. This research explores perceptions of SR in relation to flooding for householders and local businesses and establishes their relationships with experience of flooding and demographic factors of age, gender and ethnicity. The data were obtained via a questionnaire survey of three communities in Birmingham and one community in South East London, UK, three with experience of flooding and one without. A total of 414 responses were received and used in the multiple regression analysis. The analysis identified ‘experience of flooding’, ‘age’ and ‘South Asian’ ethnic group as significant variables, suggesting that older individuals from South Asian ethnic groups with previous experience of flooding are likely to be more socially responsible than others without these attributes

Thin Melanoma with Nodal Involvement: Analysis of Demographic, Pathologic, and Treatment Factors with Regard to Prognosis.

BACKGROUND: Although only a small proportion of thin melanomas result in lymph node metastasis, the abundance of these lesions results in a relatively large absolute number of patients with a diagnosis of nodal metastases, determined by either sentinel lymph node (SLN) biopsy or clinical nodal recurrence (CNR). METHODS: Independent cohorts with thin melanoma and either SLN metastasis or CNR were identified at two melanoma referral centers. At both centers, SLN metastasis patients were included. At center 1, the CNR cohort included patients with initial negative clinical nodal evaluation followed by CNR. At center 2, the CNR cohort was restricted to those presenting in the era before the use of SLN biopsy. Uni- and multivariable analyses of melanoma-specific survival (MSS) were performed. RESULTS: At center 1, 427 CNR patients were compared with 91 SLN+ patients. The 5- and 10-year survival rates in the SLN group were respectively 88 and 84 % compared with 72 and 49 % in the CNR group (p \u3c 0.0001). The multivariate analysis showed age older than 50 years (hazard ratio [HR] 1.5; 95 % confidence interval [CI] 1.2-1.9), present ulceration (HR 1.9; 95 % CI 1.2-2.9), unknown ulceration (HR 1.6; 95 % CI 1.3-2.1), truncal site (HR 1.6; 95 % CI 1.2-2.2), and CNR (HR 3.3; 95 % CI 1.8-6.0) to be associated significantly with decreased MSS (p \u3c 0.01 for each). The center 2 cohort demonstrated remarkably similar findings, with a 5-year MSS of 88 % in the SLN (n = 29) group and 76 % in the CNR group (n = 39, p = 0.09). CONCLUSION: Patients with nodal metastases from thin melanomas have a substantial risk of melanoma death. This risk is lower among patients whose disease is discovered by SLN biopsy rather than CNR

The Effects of Neurodevelopmental Lead Exposure on The NeuwirthTM Hole Board Test

This work was presented at the 2023 SUNY Student Undergraduates Research Conference (SURC).Rodent models are the primary species for pre-clinical study and experimentation for biomedical translational research. However, subsequent testing on a variety of behavioral tests as a "battery" can often result in an extraneous variable of confounding carryover effects if not carefully considered. For example, if a more stressful test is used prior to a less stressful test, inflated and artifactual increases in the latter test may be considered real. Thus, care behavioral test sequences are critical to avoid these pre-clinical testing errors that may forestall promising drug candidates for clinical phase trials. In the present study, we examined the NeuwirthTM Hole board test, which is designed to overcome these testing sequence confounds, by using the same testing apparatus over 2 days. In day 1, a 10 minute exploration trial is used to assess fear/escape behaviors. Then, 24 hrs later, 4 Petri Dishes with 4 different odors are placed below the apparatus to increase the rat's cognitive/exploratory behaviors and overcome both the prior day's anxiety-like behaviors and habituation over 2 days. We explored this testing procedure to evaluate the effects of neurodevelopmental lead exposure and how it may be a useful tool in parsing very subtle brain deficits through such a simple testing procedure. This is a pilot study that currently shows that the test can be used to determine both sex-dependent and developmental time-period differences in the rats behaviors. This testing procedure may have greater advantages for pre-clinical study that may further accelerate drug advancement to clinical phase trials.The work was supported by a SUNY Old Westbury Faculty Development Grant Awarded to Lorenz S Neuwirth.NAN/ASUNY Old Westbury, Dept. of Psychology, Old Westbury, NY 11568, USASUNY Neuroscience Research Institute, Old Westbury, NY 11568, USASUNY Old Westbury, Dept. of Biology, Old Westbury, NY 11568, USASUNY Old Westbury, Dept. of Chemistry & Physics, Old Westbury, NY 11568, USAN/

Quantum key distribution with entangled photons generated on demand by a quantum dot

Quantum key distribution-exchanging a random secret key relying on a quantum mechanical resource-is the core feature of secure quantum networks. Entanglement-based protocols offer additional layers of security and scale favorably with quantum repeaters, but the stringent requirements set on the photon source have made their use situational so far. Semiconductor-based quantum emitters are a promising solution in this scenario, ensuring on-demand generation of near-unity-fidelity entangled photons with record-low multiphoton emission, the latter feature countering some of the best eavesdropping attacks. Here, we use a coherently driven quantum dot to experimentally demonstrate a modified Ekert quantum key distribution protocol with two quantum channel approaches: both a 250-m-long single-mode fiber and in free space, connecting two buildings within the campus of Sapienza University in Rome. Our field study highlights that quantum-dot entangled photon sources are ready to go beyond laboratory experiments, thus opening the way to real-life quantum communication

Intramural Duodenal Haematoma after Endoscopic Biopsy: Case Report and Review of the Literature

The development of intramural duodenal haematoma (IDH) after small bowel biopsy is an unusual lesion and has only been reported in 18 children. Coagulopathy, thrombocytopenia and some special features of duodenal anatomy, e.g. relatively fixed position in the retroperitoneum and numerous submucosal blood vessels, have been suggested as a cause for IDH. The typical clinical presentation of IDH is severe abdominal pain and vomiting due to duodenal obstruction. In addition, it is often associated with pancreatitis and cholestasis. Diagnosis is confirmed using imaging techniques such as ultrasound, magnetic resonance imaging or computed tomography and upper intestinal series. Once diagnosis is confirmed and intestinal perforation excluded, conservative treatment with nasogastric tube and parenteral nutrition is sufficient. We present a case of massive IDH following endoscopic grasp forceps biopsy in a 5-year-old girl without bleeding disorder or other risk for IDH, which caused duodenal obstruction and mild pancreatitis and resolved within 2 weeks of conservative management. Since duodenal biopsies have become the common way to evaluate children or adults for suspected enteropathy, the occurrence of this complication is likely to increase. In conclusion, the review of the literature points out the risk for IDH especially in children with a history of bone marrow transplantation or leukaemia

Signatures of the Optical Stark Effect on Entangled Photon Pairs from Resonantly-Pumped Quantum Dots

Two-photon resonant excitation of the biexciton-exciton cascade in a quantum dot generates highly polarization-entangled photon pairs in a near-deterministic way. However, there are still open questions on the ultimate level of achievable entanglement. Here, we observe the impact of the laser-induced AC-Stark effect on the spectral emission features and on entanglement. A shorter emission time, longer laser pulse duration, and higher pump power all result in lower values of concurrence. Nonetheless, additional contributions are still required to fully account for the observed below-unity concurrence.Comment: 7 pages, 3 figure

An Assessment of Strain- And Visual Pigmentation-related Differences in Neurocognitive And Neurobehavioral Outcomes in the transgenic Cohen’s Alzheimer’s Disease Rat Model

This work was presented at the 2023 SUNY Student Undergraduates Research Conference (SURC).The global population is predicted to face a substantial rise in cases of Alzheimer’s Disease (AD) by the year 2050. To this end, we are still far from developing clear and effective pre-clinical treatments for forestalling, recovering, and preventing AD symptoms and pathological traits associated with a positive diagnosis. Pre-clinical research is critical for early stage development of effective drugs for later clinical phase trials. However, effective drugs may be moved forward as false positives when proper behavioral experimental controls or comparisons are either overlooked or lacking in the pre-clinical stages. Thus, these missteps can often delay or inappropriately advance drug candidates lacking true efficacy at this pre-clinical stage. One such pre-clinical model uses the Cohen's Alzheimer's Disease (AD) rat model which has a genetic background in the Fischer 344 (F344) rat. Unfortunately, the F344 rat is an albino rat that is visually non-pigmented with rather poor visual acuity when compared to its visually pigmented counter-parts. This raises a critical issue, that when visually non-pigmented rat models are used for pre-clinical study, much caution should be exercised as they may have an artificially truncated or reduced cognitive capacity making them a less informative model for neurocognitive and neurobehavioral evaluations. In order to assess this issue we crossed the F344 AD rat model with a Long Evans (LE) visually pigmented rat model to produce a LE AD rat model. We then compared these rats’ behavioral performances on the Open Field to assess locomotor activity, the Elevated Plus Maze to assess anxiety-like behaviors, and the NeuwirthTM-Holeboard Test to assess fear/escape vs. cognitive/exploratory behaviors over 2 days. The data revealed that across all tests that the females for each strain had increase locomotor activity, anxiety-like behaviors, and fear/escape and cognitive/exploratory behaviors. When evaluating the strains, across all tests the F344 AD rats had a lower bandwidth/range for the capacity of their behavioral deficits to be observed when compared to the LE AD rats. Thus, our findings show that if a cognitive enhancing drug and/or anxiety-like drug were to be used to treat AD through these rats in the pre-clinical testing phase that the LE AD rats would prove to be a better model as they can show a greater range of deficits with a greater range for cognitive recovery.This work was supported by a SUNY Old Westbury Faculty Development Grant Awarded to Lorenz S.
