Engagement With a Custom-Made Online System Designed to Support Undergraduate Work Placement
This paper describes an online system that was custom-made to allow BSc Optometry undergraduates to submit work electronically, while off-campus on work placement. One of the main aims of the system was to allow internal (college) supervisors to provide students with timely, formative feedback on work submitted. The system was piloted in academic year 2013-14 and an intrinsic case study was carried out to examine the engagement of the students, the external placement supervisors and the internal supervisors with the system. Engagement was gauged by examining all subjects’ interaction with the system and by asking them to complete a post placement questionnaire. The results showed a high level of engagement from both the students and external supervisors but a lower level of engagement from the internal supervisors, in particular with regard to the provision of formative feedback. Possible reasons for the different levels of engagement are discussed and changes to be made to the system for academic year 2014-15 (based on the findings of the case study) are outlined
Components Qualification for a Possible use in the Mu2e Calorimeter Waveform Digitizers
The Mu2e experiment at Fermilab searches for the charged flavor violating
conversion of a muon into an electron in the Coulomb field of a nucleus. The
detector consists of a straw tube tracker and a CSI crystal electromagnetic
calorimeter, both housed in a superconducting solenoid. Both the front-end and
the digital electronics, located inside the cryostat, will be operated in
vacuum under a 1 T magnetic field, having to sustain the high flux of neutrons
and ionizing particles coming from the muons stopping target. These harsh
experimental conditions make the design of the calorimeter waveform digitizer
quite challenging. All the selected commercial devices must be tested
individually and qualified for radiation hardness and operation in high
magnetic field. At the moment the expected particles flux and spectra at the
digitizers location are not completely simulated and we are using initial rough
estimates to select the components for the first prototype. We are gaining
experience in the qualification procedures using the selected components but
the choice will be frozen only when dose and neutron flux simulations will be
completed. The experimental results of the first qualification campaign are
presented.Comment: TWEPP 2016 - Topical Workshop on Electronics for Particle Physics,

WGEAWESS: Integrated Ecosystems Assessment of the Western European Shelf Seas
oral presentation abstractTraditionally, integrated ecosystem assessment (IEA) has been developed regionally using different strategies and tools, leading to problems of comparability and integration and even different assessments of status (e.g. GES) across shared boundaries. WGEAWESS undertakes IEA throughout the western European shelf seas to support ecosystem-based management (EBM) measures at the local, national, regional and EU levels. Relevant to key EU Directives (e.g. MSFD, WFD & CFP), IEA makes explicit links between human activities and ecosystem health, assessing the scale of impact and recovery, enabling targeted management and mitigation measures. Employing a combination of integrated trend analyses to generate time series of pressures and impacts, semi-quantitative methods to fill data gaps and inform future research effort, and reviewing and updating existing ecosystem models throughout the regions, WGEAWESS reviews and assesses patterns of human activities, their pressures, and ecosystem components to underpin the process.
WGEAWESS is developing plans to advance this work thought a large scale project that would use quantitative integrators of ecosystem functioning (indicators) in experimental platforms to assess and gain insight into pressure effects and proliferation, and to forecast futures under various management scenarios. Case study investigations, with priorities specified via direct engagement with relevant stakeholders, would enable management decisions to be based on regional and/or local priorities, and ensuring recognition of the social context. Finally, a guide on translating IEA into advice for EBM and demonstrating its practical use in informing specific issues regarding the management of ecosystem services would be produced, along with an interactive web-based ‘living’ tool which will and provide a key resource for researchers, decision-makers and the general public alike
Pre-Production and Quality Assurance of the Mu2e Calorimeter Silicon Photomultipliers
The Mu2e electromagnetic calorimeter has to provide precise information on
energy, time and position for 100 MeV electrons. It is composed of 1348
un-doped CsI crystals, each coupled to two large area Silicon Photomultipliers
(SiPMs). A modular and custom SiPM layout consisting of a 32 array of
66 mm UV-extended monolithic SiPMs has been developed to fulfill
the Mu2e calorimeter requirements and a pre-production of 150 prototypes has
been procured by three international firms (Hamamatsu, SensL and Advansid). A
detailed quality assurance process has been carried out on this first batch of
photosensors: the breakdown voltage, the gain, the quenching time, the dark
current and the Photon Detection Efficiency (PDE) have been determined for each
monolithic cell of each SiPMs array. One sample for each vendor has been
exposed to a neutron fluency up to 8.5~~10 1 MeV (Si) eq.
n/cm and a linear increase of the dark current up to tens of mA has been
observed. Others 5 samples for each vendor have undergone an accelerated aging
in order to verify a Mean Time To Failure (MTTF) higher than 10
hours.Comment: NDIP 2017 - New Developments In Photodetection, 3-7 July 2017, Tours

Inserción laboral de los graduados en la Facultad de Economía del Centro Regional Universitario de Azuero (CRUA), Universidad de Panamá: 1998-2014
The labor insertion and occupational situation of the graduates of the Faculty of Economics of CRUA was started with a descriptive cross-sectional study and a simple random sample of 162 (42% of the population). Significant percentage did not continue their academic training; more than two thirds of the graduates used a single way to access the labor market, mainly using personal contacts and professional practice. High percentage entered the labor market less than a year after completing studies, in commercial and service companies, followed by banking and financial institutions (Finance and Banking) and nonfinancial government enterprises (Economy). Most get a first full-time, indefinite-term contract with an average salary of B/. 457.65, standing 71%, in the range of B/. 500.00 or less. A high percentage of graduates perceived that their first job was "totally" or "partially” related to the training they received and that their job placement was "successful" or "very successful".Se analizó la inserción laboral y la situación ocupacional de los graduados de la Facultad de Economía del CRUA con un estudio descriptivo- transversal y una muestra aleatoria simple de 162 (42% de la población). Significativo porcentaje no ha continuado su formación académica; más de dos tercios de los graduados utilizaron una sola vía para acceder al mercado laboral, principalmente usando contactos personales y la práctica profesional. Alto porcentaje se insertó al mercado laboral a menos de un año después de culminar estudios, en empresas comerciales y de servicios, seguida de las instituciones bancarias y financieras (Finanzas y Banca) y las empresas no financieras del gobierno (Economía). La mayoría logra un primer contrato de tipo indefinido, a tiempo completo y con una media salarial de B/. 457.65, ubicándose un 71%, en el rango de B/. 500.00 o menos. Un alto porcentaje de los graduados percibía que su primer empleo se relacionó “totalmente” o “parcialmente” con la formación recibida y que su inserción laboral fue “exitosa” o “muy exitosa”
Bancarización de la población universitaria del distrito de Chitré, Herrera, Panamá, 2018-2019
Banks are vital institutions for the functioning of modern economy, allowing companies and people access to financial resources and services to achieve their investment and consumption purposes, promoting macroeconomic development and reducing poverty in countries. Banking has become the main tool for financial inclusion, promoted by states and international organizations. In 2018 and 2019, descriptive-cross-sectional research was carried out with the objective of measuring some variables related to the banking use of the university population in the District of Chitré, from the demand approach and, thereby, describing its main characteristics. The sample was stratified considering the three universities with the highest enrollment. It was observed that the levels of banking use differ between the strata since the levels for teachers and administrators are higher (97.1%) than for students (60.0%). University students bank both through savings and credit (81% and 16%, respectively), they have more than one savings account, in more than one bank, especially to carry out payment transactions. Professors and administrators handle an average of 2.3 credits and students, 1.4. Currently, it is expected that banking penetration indicators will be higher, both due to the dynamics of the advancement of financial technology and due to the positive impacts of the Covid-19 pandemic shown by the increase in the holding of savings accounts and their electronic use to carry out transactions. It is concluded that the university population can be seen as an important market niche, supporting the design of products and services and financial education programs focused on this segment of the general population.Los bancos son instituciones vitales para el funcionamiento de la economía moderna, permitiendo a empresas y personas el acceso a recursos y servicios financieros para la consecución de sus fines de inversión y consumo, propiciando el desarrollo macroeconómico y la disminución de la pobreza de los países. La bancarización se ha convertido en la principal herramienta de inclusión financiera, promovida por los estados y organismos internacionales. En el 2018 y 2019 se realizó una investigación descriptiva-transversal con el objetivo de medir algunas variables relacionadas con la bancarización de la población universitaria en el distrito de Chitré, desde el enfoque de demanda y con ello, describir sus principales características. La muestra fue estratificada contemplando tres universidades de mayor matrícula. Se observó que los niveles de bancarización se diferencian entre los estratos, pues en los profesores y administrativos estos son mayores (97.1%) que el de los estudiantes (60.0%). Los universitarios se bancarizan tanto a través del ahorro como del crédito (81% y 16%, respectivamente), poseen más de una cuenta de ahorro, en más de un banco, sobre todo para realizar transacciones de pagos. Los profesores y administrativos manejan en promedio 2.3 créditos y los estudiantes, 1.4. En la actualidad, se espera que los indicadores de bancarización sean mayores, tanto por la dinámica de avance de la tecnología financiera, como por los impactos positivos de la pandemia de Covid-19 mostrados por el aumento de la tenencia de cuentas de ahorro y su uso electrónico para realizar transacciones. Se concluye que la población universitaria puede ser vista como un nicho de mercado importante, sustentando el diseño de productos y servicios y programas de educación financiera focalizados a este segmento de la población general
Reserva Forestal El Montuoso: Vinculación económica de las comunidades de influencia con su ecosistema
The communities’ economic link to the Forest Reserve El Montuoso (FRM) was analyzed using a stra-tified cluster sampling. Communities depend on the direct benefits from this ecosystem for its survival, through the availability (87 per cent of the homes) and use of their lands for agricultural purposes (74 per cent), in rice and corn crops for self-consumption, and livestock and poultry production (76 per cent), mainly chickens and pigs. Crop and livestock farming allow residents to have access to unpaid jobs or self-employments (53 per cent) and to paid jobs, mainly for temporary farmworkers. Likewise, 67 per cent of the families generate monetary re-venues through the sale of products, mainly livestock. The families’ income indicators are all relatively low evidencing the high state of poverty of these communities. The benefits obtained by the FRM are threatened by the degradation of the ecosystem as a result of deforestation, the use of inappropriate technologies, such as tree-felling and burning, and the non-incorporation of conservation practices. Utilizando un muestreo estratificado por conglomerado, se analizó la vinculación económica de las comunidades con la Reserva Forestal El Montuoso (RFM). Las comunidades dependen, para su supervivencia, de los beneficios directos obtenidos de este ecosistema, a través de la disponibilidad (87% de los hogares) y uso de sus tierras en la agricultura (74%), en cultivos de arroz y maíz para el autoconsumo y en la producción pecuaria (76%), principalmente aves y cerdos. Las actividades agropecuarias permiten a estos habitantes acceder al empleo no asalariado o autoempleo (53%) y al asalariado, sobre todo como jornalero eventual (57%). Igualmente, el 67%de las familias genera ingresos monetarios con la venta de productos mayormente pecuarios. Todos los indica-dores de ingreso familiar son relativamente muy bajos, mostrando estas comunidades un estado de marcada pobreza. Los beneficios obtenidos de la RFM están amenazados por una degradación del ecosistema, caracteri-zado por la deforestación, uso de tecnologías no apropiadas, como tala y quema, y la no incorporación de prác-ticas de conservación
Design, status and perspective of the Mu2e crystal calorimeter
The Mu2e experiment at Fermilab will search for the charged lepton flavor
violating process of neutrino-less coherent conversion in the field
of an aluminum nucleus. Mu2e will reach a single event sensitivity of about
that corresponds to four orders of magnitude improvements
with respect to the current best limit. The detector system consists of a straw
tube tracker and a crystal calorimeter made of undoped CsI coupled with Silicon
Photomultipliers. The calorimeter was designed to be operable in a harsh
environment where about 10 krad/year will be delivered in the hottest region
and work in presence of 1 T magnetic field. The calorimeter role is to perform
/e separation to suppress cosmic muons mimiking the signal, while
providing a high level trigger and a seeding the track search in the tracker.
In this paper we present the calorimeter design and the latest RD results.Comment: 4 pages, conference proceeding for a presentation held at TIPP'2017.
