CALIS - A CALibration Insertion System for the DarkSide-50 dark matter search experiment
© 2017 The Author(s). This paper describes the design, fabrication, commissioning and use of a CALibration source Insertion System (CALIS) in the DarkSide-50 direct dark matter search experiment. CALIS deploys radioactive sources into the liquid scintillator veto to characterize the detector response and detection efficiency of the DarkSide-50 Liquid Argon Time Projection Chamber, and the surrounding 30 t organic liquid scintillator neutron veto. It was commissioned in September 2014 and has been used successfully in several gamma and neutron source campaigns since then. A description of the hardware and an excerpt of calibration analysis results are given below

Studio CALIS (Cancer Literacy and Information Seeking) : il ruolo dell'helath literacy, Enpowerment e Information Seeking Behaviour nell'adesione agli screening oncologici
I programmi di screening oncologici necessitano di strategie per implementarne l’adesione. Tra i molteplici fattori che ne influenzano la partecipazione gioca un ruolo decisivo il livello di conoscenze in ambito di tutela della salute (Health Literacy-HL): concetto multidimensionale che si correla anche al concetto di Empowerment (Emp) ed al comportamento relativo alla ricerca di informazioni (Information Seeking Behavior-ISB) [Schulz&Nakamoto 2005]. I soggetti con bassa HL partecipano meno agli screening, mentre gli individui che ritengono di avere una buona conoscenza rispetto ad un determinato tema tendono a cercare meno informazioni, il che si riflette negativamente sui livelli di HL ed Emp e di conseguenza sugli esiti di salute. Inoltre, è noto che i pazienti oncologici presentano un livello di HL mediamente elevato ma non vi sono conoscenze in merito a come esso sia stato raggiunto.
L’obiettivo dello studio è duplice: studiare il ruolo giocato da HL, Emp e credenze dell’individuo relativamente allo screening per il cancro del colon-retto (CCR) ed alla malattia nella decisione di aderire o meno allo screening (CALIS I), e capire come l’ISB si modifica nel tempo e come i pazienti oncologici riescano a raggiungere elevati livelli di HL (CALIS II)

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
Answering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
Impact of temperature and biomass augmentation on biosulfur-driven autotrophic denitrification in membrane bioreactors treating real nitrate-contaminated groundwater
Nitrate (NO3-) contamination of groundwater is a major health concern worldwide as it can lead to serious illnesses such as methemoglobinemia and cancer. Autotrophic denitrification is a smart approach for treating groundwater, being typically organic-deficient. Lately, biogenic sulfur (S0bio) has emerged as a sustainable, free, and high-efficiency substrate to fuel membrane bioreactors (MBRs) treating contaminated groundwater. However, the effects of moderate temperature and biomass concentration on the performance and fouling of the S0bio-fed MBR were not investigated previously. This study shows that biomass levels of ~1 g MLVSS/L limit membrane fouling but also denitrification efficiency. Biomass augmentation up to 3 g MLVSS/L enhanced denitrification but worsened fouling due to increase of extracellular polymeric substance (EPS) levels in the bulk liquid. Temperature decrease from 30 °C to 20 °C halved denitrification efficiency, which could be partially recovered through bioaugmentation. The mechanisms affected by temperature decrease, practical applications, and future research needs were discussed
