No full textI PERCORSI LAVORATIVI: FOCUS SULLA NUOVA EMIGRAZIONE ITALIANA
No full textNel saggio sono presentati i risultati salienti di un lavoro di ricerca che l’autrice ha condotto in seno ad un gruppo di lavoro dell’Università degli Studi di Salerno . Il contributo si concentra esclusivamente sui protagonisti della
“nuova emigrazione italiana”, volendo con questa espressione intendere l’emigrazione iniziata nel
2008 in corrispondenza della crisi economica che ha investito l’Italia .
Il caso di studio interessa una direttrice migratoria Sud-Sud non prevalente e poco esplorata , che
purtuttavia è parte del flusso della nuova emigrazione italiana che, oltre alle mete più consolidate,
presenta nuove e varie direzioni. All’interno di tale direttrice sono stati studiati i percorsi lavorativi
e gli aspetti che risultano più strettamente collegati alla ricerca del lavoro e all’inserimento
lavorativo.
Per fare emergere i nodi significativi sono stati presi in considerazione il titolo di studio, le
condizioni individuali e familiari, il sostegno familiare (assenza/ presenza), la posizione lavorativa,
la relazione tra qualifica professionale e tipologia di lavoro svolto, nonché le precedenti esperienze
migratorie. L’analisi ha, inoltre, messo in relazione gli aspetti sopra elencati con le varie fasi del
progetto migratorio elaborato da ogni singolo intervistato: quello iniziale, quello attuale e quello
futuro (restare/partire).
In questo saggio, dopo aver descritto brevemente gli elementi che caratterizzano il gruppo di
intervistati considerato e i percorsi di inserimento lavorativo, si discuterà dei fattori di
spinta e si proporranno alcune riflessioni sul “nuovo lavoratore europeo” e sulla
“mobilità economica”. Al termine di questo percorso di analisi non si propongono
conclusioni ma si aprono ulteriori interrogativi per gli sviluppi futuri del nostro lavoro
A case study of the 2018 Allegheny County Health Department core competency assessment
No full textMaintaining a competent and qualified public health workforce is crucial to delivering the Ten Essential Services and three core functions of public health. The Core Competencies for Public Health Professionals reflect foundational skills applicable to the research and practice of public health. Core competencies are a piece in the public health accreditation process and serve as a starting point for workforce development at local, state, and tribal agencies. Through assessment of these competencies, and as part of the public health accreditation process, agencies can identify training needs and create a workforce development plan. The Allegheny County Health Department (ACHD) first assessed their staff against the core competencies, in 2014 during their initial application for accreditation. Recently, the same assessment tool was administered in 2018 to measure the impact of workforce development activities, as well as prepare ACHD for their upcoming reaccreditation application.
Measuring the long-term outcomes of accreditation, through workforce development, is crucial for public health agencies. Through evidence-based results, agencies can describe the impact of accreditation, demonstrated by a competent qualified workforce able to meet the needs of the community, and deliver the Ten Essential Services, and three core functions of Public Health.
ACHD adapted an assessment tool developed by the Public Health Foundation. The tool provided a baseline and comparative assessment in 2014, and 2018 respectively. Respondents were able to self-rate their perceived level of skill anonymously against each identified competency. The assessment period was conducted from September 4th-24th, 2018.
In 2018, all active employees at ACHD during the assessment period completed the survey. Compared to the initial survey in 2014, the ACHD observed an increase in overall domain competencies across all 8 domains (D1-D8). ACHD staff ranked highest in Policy Development/Program Planning (D2, avg. 2.895), Communication Skills (D3, avg. 2.983), and Cultural Competency Skills (D4, avg. 2.971).
Limitations of self-assessment data must be considered when using these results for workforce development planning. Self-assessment bias and workforce changes, such as internal job restructuring, were identified as limitations. Therefore, limiting the depth of the analysis. Regardless, the increase in competencies across the domains suggest workforce development at ACHD has been successful and should be continued
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Hypovitaminosis D Is Associated with Liver Insulin Resistance in Obese Subjects
No full textHypovitaminosis D is highly prevalent in obese subjects. Serum 25-hydroxy vitamin D3 [25(OH)D] concentration, the best marker of human vitamin D status, has been reported to be associated with glucose status, insulin resistance (IR) and beta cell function. To specifically investigate the relationship between 25(OH)D and liver IR we performed a comprehensive metabolic assessment (2-h OGTT, hyperinsulinemic euglycemic clamp [HEC], body composition by DXA) in 20 obese non-diabetic subjects (42.9±2.7 yrs; BMI 37.7±0.8 kg/m2) with 25(OH)D insufficiency (<30 ng/mL). Liver IR was estimated using the index by Vangipurapu et al. (-0.091 + [log insulin AUC 0-120 min x 0.400] + [log fat mass% x 0.346] - [log HDL cholesterol x 0.408] + [log BMI x 0.435]). There was a significant inverse correlation between 25(OH)D and the liver IR index (r = -0.514, p = 0.02). This correlation maintained its significance after adjusting for age, gender, total cholesterol, triglycerides and whole body insulin sensitivity (M value assessed by HEC) in multiple linear regression analysis. There was no significant correlation between 25(OH)D and beta cell function estimated by the Disposition Index. Our data suggest that, in obese subjects, low 25(OH)D levels are independently associated with liver insulin resistance, but not with beta cell function. Further studies are needed to clarify the relationship between glucose homeostasis and vitamin D levels
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
