In 2014, the health and productivity team of the disability insurance provider, Unum, conducted a mixed methods study that included qualitative interviews with internal mental health disability claims professionals, and external interviews with employers. Quantitative data of 15 employers were analysed to identify descriptive statistics involving mental health short-term disability (STD) claims. Workplace factors were examined to understand best practices among companies, related to mental health STD, to identify work environments that may increase or decrease mental health disabilities. Quantitative data found workers aged 40 to 49 had the highest rates of mental health STD claims and workers aged 50 to 59 had the longest duration of absence. Anxiety and depression were the main reasons for mental health absences from work. Results from the qualitative interviews showed a supportive work culture (i.e., work–life balance, good benefits, successful wellness programs) may lead to higher STD claim rates, demonstrating workers in these environments may feel more comfortable disclosing and seeking help for mental health disabilities. Conclusions from this study indicate that although presenteeism rates for mental health are high and impact employers financially, having higher STD claim rates may be more cost effective than having employees with mental health conditions remain at work instead of filing STD claims, seeking treatment and returning to productive employment. Employee age can impact rate and duration of mental health STD claims, meaning employers should implement workplace practices that support overall mental health of employees.
Multiwords are words in which a single symbol can be replaced by a nonempty set of symbols. They extend the notion of partial words. A word w is certain in a multiword M if it occurs in every word that can be obtained by selecting one single symbol among the symbols provided in each position of M. Motivated by a problem on incomplete databases, we investigate a variant of the pattern matching problem which is to decide whether a word w is certain in a multiword M. We study the language CERTAIN(w) of multiwords in which w is certain. We show that this regular language is aperiodic for three large families of words. We also show its aperiodicity in the case of partial words over an alphabet with at least three symbols.
It is 20 years since the passage of the Americans With Disabilities Act, yet employment and economic inequities continue for people with disabilities. The purpose of this article is to inform and encourage disability management leading practices to contribute toward reducing these disparities. The approach is an examination of where in the employment process applicants and incumbent employees perceive employment disability discrimination, leading to the filing of charges against an employer. Employment disability discrimination claims filed by individuals over 15 years (1993–2007) with the United States (US) Equal Employment Opportunity Commission or state and local Fair Employment Practice Agencies are studied. The authors analyse employment discrimination charges by year, basis (i.e., protected class characteristics, such as disability, age, or race), issue (i.e., actions of the employer, such as discharge, hiring, or harassment), employer characteristics (i.e, size of business and industry sector), and joint filings under Title VII of the Civil Rights Act (gender, race/ethnicity, and religious discrimination) and the Age Discrimination in Employment Act (ADEA). Special attention is paid to where in the employment process people with specific impairments are perceiving discrimination. Implications of these research findings for the practice and administration of disability management and employer policies are discussed.
We study hybrid systems with strong resets from the perspective of
formal language theory. We define a notion of hybrid regular
expression and prove a Kleene-like theorem for hybrid systems. We
also prove the closure of these systems under determinisation and
complementation. Finally, we prove that the reachability problem is
undecidable for synchronized products of hybrid systems.
We show that the inclusion problem is decidable for rational languages
of words indexed by scattered countable linear orderings. The method leans on a reduction to
the decidability of the monadic second order theory of the infinite binary tree
The WHO recommends a daily Ca intake for postmenopausal women of 1300 mg. The objective of the present study was to assess the dietary Ca intake in European postmenopausal osteoporotic women.
Design, setting and subjects
Assessment of dietary Ca intake (food and supplements) was performed with a validated self-questionnaire in 8524 osteoporotic women from nine European countries (Belgium, Denmark, France, Germany, Hungary, Italy, Poland, Spain and the UK).
Mean age of the patients was 74·2 (sd 7·1) years, mean BMI was 25·7 (sd 4·2) kg/m2. Of the study population, 37·2 % of the women took Ca supplements. The mean dietary intake of Ca was 930·7 (sd 422·9) mg/d. The lowest Ca intake was found in Hungary (586·7 (sd 319·1) mg/d) and the highest in Denmark (1145·6 (sd 463·0) mg/d). In the whole study population, only 19·1 % of the women had a dietary Ca intake >1300 mg/d. Only 17·1 % of women aged over 75 years achieved 1300 mg/d compared with 20·5 % of women aged less than 75 years (P = 0·0001 for the difference between the two groups).
Dietary intake of Ca is very low in European postmenopausal women. A greater awareness is needed to resolve this public health problem.
The aging workforce is likely to result in increasing numbers of workers with disabilities. The US Census Bureau projects that the 45- to 54- and 55- to 64-year-old population in the United States will grow by nearly 44.2 million (17%) and 35 million (39%) in the next 10 years (US Census Bureau, 2004). By the year 2010, this group will account for nearly half (44%) of the working age population (20–64), and the number of people with disabilities between the ages of 50 and 65 will almost double (Weathers, 2006). Disability management and accommodation policies and practices readily lend themselves to addressing the challenges employers will face with an aging workforce, and the increasing prevalence of disability that these demographics bring. Proactive education about ways to maximise the productivity of an aging workforce, effective case management, and workplace accommodation can significantly contribute to maximising aging worker retention.
Introduction. The severe impact of papaya bacterial canker in the West Indies justified launching a program to transfer the genetic resistance/tolerance identified in local germplasm to good-quality cultivars. As a first step, a germplasm collection from the Caribbean was gathered and its morphological and genetic diversity assessed. Materials and methods. The total sample included 50 accessions from the Lesser Antilles, Cuba, Venezuela, Costa Rica and Hawaii. Morphological data from a subsample of 29 accessions were submitted to analysis of variance, principal component analysis and Neighbor-Joining cluster analysis. Nine isozyme systems were tested, and the corresponding data were processed for cluster analysis and genetic parameters, including the fixation index, diversity indices and heterozygosity. Results. Eighteen of the 47 Caribbean and Venezuelan accessions exhibited hermaphroditism. Venezuelan accessions displayed the widest morphological diversity, while those from Barbados were distinguished by fruit quality. Sexual type affected leaf and flower traits. Cluster analysis shows little morphological differentiation between origins, with the relative grouping of the accessions from Guadeloupe or Barbados. Only four isozyme systems were polymorphic, producing 34 distinct zymotypes, with a relatively high heterozygosity and a particular diversity in Venezuela, Guadeloupe and Barbados. Geographic structuration appears limited in the cluster analysis among individuals; however, it is clearer when considering the six best-represented populations, with one cluster representing Venezuela, Trinidad and Barbados, and one for Guadeloupe, Martinique and Grenada. Discussion. The low level of fixation is attributed to dioecy and to the low level of selection. The relative isolation of island populations has favored geographic differentiation, albeit limited. The differentiation between the good-quality germplasm from Barbados and the tolerant populations from Martinique and Guadeloupe encourages the development of a marker-assisted introgression scheme.
Background: Divergences in cognitive disturbances in hypothyroidism
reported in the literature are a result of a methodological bias. Methods:
By using a precise methodology, we examined attention and executive
functions in hypothyroidism, verified the presence of anxiety and
depressive symptoms in hypothyroidism, and examined the possible link
between these symptoms and the cognitive disturbances (searching for
attentional bias for words with a negative emotional valence). We
administered a battery of cognitive tests to 23 participants who had
undergone thyroidectomy for thyroid carcinoma: for the first time in an
euthyroid state, then 3 weeks later (still in the euthyroid state) to
assess the test/retest effect, and finally 4 weeks later in an
hypothyroid state. We compared their performance with that of a group of
26 control participants who were also administered the same cognitive
tests, also 3 times. Results: In hypothyroidism, the thyroid participants
were more anxious and depressed than the controls and presented
attentional and executive disturbances that reflected general slowing and
difficulties in using their capacities of inhibition. However, they did
not exhibit an attentional bias for words with a negative emotional
valence. Conclusions: Contrary to what was expected, symptoms of anxiety
and not symptoms of depression interfered with the cognitive performance
of participants in hypothyroidism. (JINS, 2005, 11,
The increase of the gate leakage current of advanced
CMOS technologies makes standard electrical characterization
methods as C(V) measurement or charge pumping more complex and
uncertain. In this paper, and based on C(V) characteristics,
main elements that directly affect the electrical measurements
of ultra thin MOS devices are clarified. Then, classical parameter
extraction techniques are reviewed, pointing out their absolute
limitations or giving potential keys of improvement.
The Journal of the International Neuropsychological Society published recently a paper that should become influential shortly. However, given its potential impact, this study has to be examined carefully.
Las herramientas computerizadas actuales permiten la exploración detallada de la estructura y el funcionamiento de la “caja negra”, es decir, los sistemas cognitivo y afectivo humanos, así como el pensamiento. Se utilizó esta tecnología para estudiar la percepción visual de emociones expresadas facialmente. La transición morfológica de una emoción canónica a otra llevó a la creación de un continuo de imágenes intermedias, y se midió la identificación de las emociones percibidas por 65 sujetos normales. Llamamos a esta aplicación “MARIE” (en francés: Méthode d’Analyse et de Recherche de l’Integration des Emotions; Método de Estudio y Análisis de la Integración de las Emociones). Nuestro estudio examinó la relación entre la modificación cuantitativa del continuo y la variación cuantitativa de las respuestas. La estandarización de los gráficos llevó a la evaluación de los dos parámetros de una curva de Laplace-Gauss, es decir, la media y la desviación típica. Se propone que esta herramienta podría ser muy útil en la evaluación clínica del estado emocional de los sujetos, los pacientes o ambos.
As a part of the Arcelor project concerning the prediction of the capability
(“ Évaluation Prévisionnelle des Capabilités ” project), models are developed to predict
the mechanical properties of austenitic stainless steel coils processed on the Ugine&ALZ
integrated cold rolling line LC2i. Two approaches are used: statistical models resulting
from an analysis of industrial databases, and physical based modelling accounting for the
recrystallization mechanism during the final annealing to estimate the mechanical behaviour
of the final product, including twinning and martensite induced transformation mechanisms.
The work leads to the prediction of the yield stress and the tensile strength along the
cold-rolled and annealed coil; the calculated mechanical values are in good agreement with
the measurement on samples taken from coils of AISI 304 grade (UGINOX 18-9 E).
A new filler material, a stabilized ferritic welding wire, has been developed
for the joining of the stabilized ferritic stainless steel sheets increasingly
used in automotive exhaust systems. The joints obtained in the GMAW and GTAW
processes behave at least as well in service as those obtained with austenitic
filler wires. The new welding grade can also be applied to produce
Current computerized tools allow detailed exploration of the structure and functioning of the “black box,” i.e., human cognitive and affective systems as well as thought. This technology was used to study the visual perception of facially expressed emotions. Morphological transition from one canonical emotion to another led to the creation of a continuum of intermediary pictures, and the identification of perceived emotions by 65 normal subjects was measured. We call this application “MARIE” (in French: Méthode d’Analyse et de Recherche de l’Intégration des Émotions; Method of Study and Analysis of Integration of Emotions). Our study examined the relationship between the quantitative modification of the continuum and the quantitative variation of the responses. Standardization of graphs led to the assessment of the two parameters of a Laplace-Gauss curve, i.e., mean and standard deviation. It is argued that such a tool could be very useful in the clinical assessment of the emotional state of subjects and/or of patients.
Behavioral studies have shown that two different
morphed faces belonging to the same identity are harder
to discriminate than two faces stemming from two different
identities. The temporal course of this categorical perception
effect has been explored through event-related potentials.
Three kinds of pairs were presented in a matching task:
(1) two different morphed faces representing the same identity
(within), (2) two other faces representing two different
identities (between), and (3) two identical morphed faces
(same). Following the second face onset in the pair, the
amplitude of the right occipitotemporal negativity (N170)
was reduced for within and same pairs as compared with
between pairs, suggesting an identity priming effect. We
also observed a modulation of the P3b wave, as the amplitude
of the responses for within pairs was higher than for between
and same pairs, suggesting a higher complexity of the task
for within pairs. These results indicate that categorical
perception of human faces has a perceptual origin in the
right occipitotemporal hemisphere.
High level waste repositorie facilities are complex systems : the parameters, processes, their interactions and the relationships between the system and its environment are numerous. Lack of knowledge and variability of parameters in the field we are studying and the time periods we require to consider, generate uncertainty which may be hard to evaluate and may affect sensitive factors (ex: human intrusion).
