Commodification, the Welfare State and Israeli Kibbutz

The notion of commodification refers to the degree to which the individual is dependent upon the market for the satisfaction of his economic and social needs. The welfare state has been described as having a decommodifying influence in that it provides the individual with the means to maintain a reasonable standard of living while not working. An examination of the Israeli Kibbutz is undertaken in order to understand the workings of an extreme case of decommodification. In Kibbutzim, there exists a very highly developed system of welfare services that arc determined by individual needs and not by individual earning power. While the nature of these communities clearly prevent direct comparisons with the welfare state, the very fact that such highly decommodified societies have existed for over seven decades should shed light on the debate over the degree to which states can intervene with the play of market forces

The scientific heritage of Richard Henry Dalitz, FRS (1925-2006)

Professor Richard H. Dalitz passed away on January 13, 2006. He was almost 81 years old and his outstanding contributions are intimately connected to some of the major breakthroughs of the 20th century in particle and nuclear physics. These outstanding contributions go beyond the Dalitz Plot, Dalitz Pair and CDD poles that bear his name. He pioneered the theoretical study of strange baryon resonances, of baryon spectroscopy in the quark model, and of hypernuclei, to all of which he made lasting contributions. His formulation of the "$\theta-\tau$ puzzle" led to the discovery that parity is not a symmetry of the weak interactions. A brief scientific evaluation of Dalitz's major contributions to particle and nuclear physics is hereby presented, followed by the first comprehensive list of his scientific publications, as assembled from several sources. The list is divided into two categories: the first, main part comprises Dalitz's research papers and reviews, including topics in the history of particle physics, biographies and reminiscences; the second part lists book reviews, public lectures and obituaries authored by Dalitz, and books edited by him. This provides the first necessary step towards a more systematic research of the Dalitz heritage in modern physics. The present 2016 edition updates the original 2006 edition, published in Nucl. Phys. A 771 (2006) 2-7, doi:10.1016/j.nuclphysa.2006.03.007, and 8-25, doi:10.1016/j.nuclphysa.2006.03.008, by including for the first time a dozen or so of publications, found recently in a list submitted to the Royal Society by Dalitz in 2004, that escaped our attention in the original version.Comment: updates the original edition by including several publications, mostly in category III, that were unknown to us in 200

Does Social Work Education Have an Impact on Social Policy Preferences? A Three-Cohort Study

This article examines the impact of social work education on the social policy preferences of social work students through a panel study of three cohorts of students at three universities in two countries - the United States and Israel. The findings of the study indicate that though the initial policy preferences of the students at the beginning of their studies at the three universities differed, by the end of their studies, the students\u27 preferences were similar and supportive of the welfare state model

Social Work Education as Professional Socialization: A Study of the Impact of Social Work Education Upon Students\u27s Professional Preferences

Professional socialization in social work is the subject of the panel study described in this article. It focuses upon the impact of different social work education programs upon the professional preferences of students in the United States and Israel. The findings indicate that significant change with regard to some of the variables did occur between the beginning and completion of studies. This generally took the form of a decline in preferences though a number of cross-culture differences were observed. The implications of the findings for the issue of professional socialization in social work are discussed

Quantum \v{C}erenkov Radiation: Spectral Cutoffs and the Role of Spin and Orbital Angular Momentum

We show that the well-known \v{C}erenkov Effect contains new phenomena arising from the quantum nature of charged particles. The \v{C}erenkov transition amplitudes allow coupling between the charged particle and the emitted photon through their orbital angular momentum (OAM) and spin, by scattering into preferred angles and polarizations. Importantly, the spectral response reveals a discontinuity immediately below a frequency cutoff that can occur in the optical region. Specifically, with proper shaping of electron beams (ebeams), we predict that the traditional \v{C}erenkov radiation angle splits into two distinctive cones of photonic shockwaves. One of the shockwaves can move along a backward cone, otherwise considered impossible for \v{C}erenkov radiation in ordinary matter. Our findings are observable for ebeams with realistic parameters, offering new applications including novel quantum optics sources, and open a new realm for \v{C}erenkov detectors involving the spin and orbital angular momentum of charged particles.Comment: 27 pages, 3 figure

CRISPR/Cas9-mediated mutagenesis of CAROTENOID CLEAVAGE DIOXYGENASE 8 in tomato provides resistance against the parasitic weed Phelipanche aegyptiaca.

Broomrapes (Phelipanche aegyptiaca and Orobanche spp.) are obligate plant parasites that cause extreme damage to crop plants. The parasite seeds have strict requirements for germination, involving preconditioning and exposure to specific chemicals strigolactones [SLs] exuded by the host roots. SLs are plant hormones derived from plant carotenoids via a pathway involving the Carotenoid Cleavage Dioxygenase 8 (CCD8). Having no effective means to control parasitic weeds in most crops, and with CRISPR/Cas9 being an effective gene-editing tool, here we demonstrate that CRISPR/Cas9-mediated mutagenesis of the CCD8 gene can be used to develop host resistance to the parasitic weed P. aegyptiaca. Cas9/single guide (sg) RNA constructs were targeted to the second exon of CCD8 in tomato (Solanum lycopersicum L.) plants. Several CCD8Cas9 mutated tomato lines with variable insertions or deletions in CCD8 were obtained with no identified off-targets. Genotype analysis of T1 plants showed that the introduced CCD8 mutations are inherited. Compared to control tomato plants, the CCD8Cas9 mutant had morphological changes that included dwarfing, excessive shoot branching and adventitious root formation. In addition, SL-deficient CCD8Cas9 mutants showed a significant reduction in parasite infestation compared to non-mutated tomato plants. In the CCD8Cas9 mutated lines, orobanchol (SL) content was significantly reduced but total carotenoids level and expression of genes related to carotenoid biosynthesis were increased, as compared to control plants. Taking into account, the impact of plant parasitic weeds on agriculture and difficulty to constitute efficient control methods, the current study offers insights into the development of a new, efficient method that could be combined with various collections of resistant tomato rootstocks

What Kind of Social Policy do Social Work Students Prefer? A Comparison of Students in Three Countries

The goal of this article is to contribute to our understanding of the way in which students at the very beginning of their social work training view the sources of social problems and the way in which society should deal with these problems. This is part of an effort to determine the contemporary role of social change in the thinking of social workers in different national settings. Traditionally, social work has regarded social change as one of its primary professional objectives. Ever since the settlement houses were first established in the late years of the 19th century, many social workers have indeed been actively involved in social action aimed at bringing about social reform for the betterment of deprived segments of society. These efforts first took place in a period during which the term welfare state had yet to be coined and the notion of state responsibility for social protection for the poor was not widely accepted. Nevertheless, the conviction of these early social workers that social conditions were the prime cause of deprivation and poverty led them to actively seek improved social legislation and programs (Addams, 1910: Leighninger and Midgley, 1997)

Galaxy Groups Associated with Gravitational Lenses and H_0 from B1608+656

Compact groups of galaxies recently have been discovered in association with several strong gravitational lens systems. These groups provide additional convergence to the lensing potential and thus affect the value of H_0 derived from the systems. Lens system time delays are now being measured with uncertainties of only a few percent or better. Additionally, vast improvements are being made in incorporating observational constraints such as Einstein ring structures and stellar velocity dispersions into the lens models. These advances are reducing the uncertainties on H_0 to levels at which the the effects of associated galaxy groups may contribute significantly to the overall error budget. We describe a dedicated multiwavelength program, using Keck, HST, and Chandra, to find such groups and measure their properties. We present, as a case study, results obtained from observations of the CLASS lens system B1608+656 and discuss the implications for the value of H_0 derived from this system.Comment: To appear in Proceedings of IAU Symposium 225: Impact of Gravitational Lensing on Cosmology, 6 pages, 2 figure

The influence of a good relationship between the internal audit and information security functions on information security outcomes

Given the increasing financial impact of cybercrime, it has become critical for companies to manage information security risk. The practitioner literature has long argued that the internal audit function (IAF) can play an important role both in providing assurance with respect to information security and in generating insights about how to improve the organization\u27s information security. Nevertheless, there is scant empirical evidence to support this belief. Using a unique data set, this study examines how the quality of the relationship between the internal audit and the information security functions affects objective measures of the overall effectiveness of an organization\u27s information security efforts. The quality of this relationship has a positive effect on the number of reported internal control weaknesses and incidents of noncompliance, as well as on the numbers of security incidents detected, both before and after they caused material harm to the organization. In addition, we find that higher levels of management support for information security and having the chief information security officer (CISO) report independently of the IT function have a positive effect on the quality of the relationship between the internal audit and information security functions
