A method of inclusion probability proportional to size selection
Creators: name: Gupta, V. K.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The purpose of this article is to propose a procedure for selecting an inclusion probability proportional to size sample n. The simplicity in sample selection and in computing joint inclusion probabilities is achieved by using the combinatorial properties of balanced incomplete block designs. The proposed method gives the same second order inclusion probabilities as that of Midzuno-Sen's procedure.

description: Despite making significant strides in system characterization using fine grained instrumentation or macroanalysis, it is still a challenging task to understand and predict the behaviour of a computer system. The thesis of this paper is that there is a correlation between memory modification patterns and the high-level behavior of the system. To explore this property, we propose a holistic observation of a system’s memory using a non-intrusive approach for sampling and analysis. Our preliminary results have demonstrated that holistic memory observation is feasible and does indeed correlate with system’s condition. We conclude with a discussion on future research directions potentially enabled by our findings.
GADO: A Genetic Algorithm for Continuous Design Optimization
Creators: name: Rasheed, Khaled
Publisher: name: Rutgers University
Year: 1998

description: Genetic algorithms (GAs) have been extensively used as a means for performing global optimization in a simple yet reliable manner. However, in some realistic engineering design optimization domains a general purpose GA is often inecient and unable to reach the global optimum. In this thesis we describe a GA for continuous designspace optimization that uses new GA operators and strategies tailored to the structure and properties of engineering design domains. Empirical results in several realistic engineering design domains as well as benchmark design domains demonstrate that using our system can greatly decrease the cost of design space search, and can also improve the quality of the resulting designs.

Abortion

description: This chapter offers new estimates of how the global gag rule has affected abortion rates across developing countries in four regions: Latin America and the Caribbean, Eastern Europe and Central Asia, South and Southeast Asia, and Sub-Saharan Africa. The regression analysis follows a “difference-in-difference” strategy that is commonly used in statistical analyses to estimate the impact of a policy change or a new program. The main finding is that the global gag rule is associated with a very large increase in abortion rates in Latin America and the Caribbean. In this region, women in countries that were highly exposed to the global gag rule had more than three times the odds of having an abortion after the global gag rule was reinstated in 2001 compared to women in less exposed countries and before the reinstatement of the policy. This effect is even larger than it is for Sub-Saharan Africa, where women in highly exposed countries had about twice the odds of having an abortion after the 2001 reinstatement of the policy compared to women in less exposed countries and before the policy was reinstated.

For this purpose, they use the notion of "relevance quotient" largely employed in other works. Then, they take from quantum mechanics the notion of "observable", that is an operator on the space of the state vectors, and they obtain a probability of transition between the states of a system in which a correlation factor is present, depending on the base states through which the system can change. So that, one can inglobe a correlation effect within a probabilistic statement.

Aggregate units, within-group inequality and the decomposition of inequality measures
Creators: name: Frosini, B. V.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The decomposition of inequality measures according to within-group and between-group contributions has been addressed up to now (a) to identifying measures which satisfy in a natural way such decomposition, being characterized by special regularity assumptions, and (b) to the preliminary determination of the between-group inequality as the most primitive one, letting the within-group term as residual with respect to total inequality. Both approaches reveal some drawbacks in the use and interpretation of inequality measures. Therefore an alternative approach is proposed, which is applicable—as well as (b)—to every inequality measure we start from a distribution reflecting only the within-group inequality, so that the corresponding measure Iw can be computed, leaving the between group term IB as a residual with respect to the total inequality I.
This procedure assumes that the groups are composed by the same number m of aggregate units, or by some replicas of the same distribution of aggregate units; on this basis an "average percentile distribution" is defined as a distribution averaged over all groups, clearly responsible for the within-group inequality; actually the Lorenz curve of this distribution appears as a weighted mean of the group Lorenz curves. As a rule the application of this procedure to particular inequality measures requires the computation of the average percentile distribution; however, for the Gini ratio and the relative mean deviation with respect to the median Iw turns out to be the weighted mean of the measures computed on the groups. In the last paragraph the above procedure is applied to several Pareto distributions, composed of two or four groups.

description: This chapter focuses on the structural drivers and constraints associated with the transition of women from unremunerated or low-paid production to higher-value work in three important labor market domains: entrepreneurship, agriculture, and wage employment. Understanding the drivers behind these types of employment and the constraints that women face can help to develop new policies that better support workers and their families, stimulate employment generation in countries with rapid labor force growth, and promote entrepreneurial activities that spur innovation and progress. In the spirit of these objectives, this chapter examines best practices in transforming women to be successful entrepreneurs, farmers, and wage workers. The chapter closes with the links between gender equality and economic growth, concluding that promoting gender equality can be a “gender-smart” way to achieve sustained economic development.

description: OBJECTIVES: To determine the relationship between head injuries sustained during each fall with various known high risk health and demographic factors predictive of falls. DESIGN: Prospective cohort study conducted over 1 year SETTING: Assisted living and skilled nursing units of a Continuing Care Retirement Community located in the northeastern United States. PARTICIPANTS: Sixty nine OAs who fell. MEASUREMENTS: Age, gender, diagnosis, high risk medication, functional, cognitive, ambulation/elimination status, mode of locomotion, fall related symptoms and the position of the fall, were analyzed using General Estimating Equations among elderly fallers with and without head injury. RESULTS: A total of 173 falls (average of 2.9 times) were observed for 62 patients who had complete injury data. Injuries were recorded in 40.5% of falls, with 41.4% being head injuries. Head injuries were more likely to be hematomas than lacerations (66.7% vs. 14.7%) and among assisted living residents (p=0.04). Head injured patients were more likely to be walking at the time of the fall (69% vs. 36.1%) and less likely to have bowel incontinence (3.5% vs. 28.5%; p=0.04). None of the high risk diagnosis or medications associated with falls risk increased risk for head injury. CONCLUSION: Those at greatest risk for head injury were ambulatory assisted living residents. None of the known clinical conditions predictive of risk to fall were predictive of head injury. For head injury prevention to be successful we need a closer examination of resident’s mobility, shoe-wear, health behavior with respect to ability to use assistive devices, and floor surface landing area. Future health policy implications include measures to ensure standard of care practices for head injured patients are in place.

description: The hotel cleaner was knocking on the door, telling him it was time to check out. But he didn’t want to leave. He had hardly slept and hadn’t eaten since a meal on the plane from Dubai the day before. The man who had met him at the airport in Jakarta had taken his false passport and, as a final payment, almost all of his money. “Okay, okay, finish,” said the cleaner knocking on the door. “Finish, finish.” He had called his wife, Sultana, to tell her he’d arrived. She sounded groggy on the phone, and when he asked why, she told him it was the middle of the night where she was, in the Yemeni port city of Aden. Only then did he realise he was in a time zone several hours ahead of the Middle East. He had spent US$50 on the room and had just $20 left in his pocket. His plan was to visit the local office of the UN refugee agency, UNHCR, where he hoped to find support and accommodation. Then, with any luck, he’d be leaving Jakarta to find a new home for him and his family. This is the story of Mohammad Abdul Aziz Osman, a Somali refugee who has lived on his wits on the streets of Jakarta for nearly four years. Like thousands of other refugees in transit countries like Indonesia, he is stuck in limbo and cut off from family and support

Year: 2013

description: Lauritzen, in his book "Statistical models as extremal families", criticizes the usual procedure of giving in advance the statistical model and then applying the various inference principles, and states that the statistical analysis and the statistical model ought to be jointly considered. The technique which he suggests for the construction of a statistical model, may be traced, although in a simpler context , also in a theorem by Diaconis and Freedman. From a predictive view point the same problem has been also dealt with by Cifarelli and Regazzini. We present a new, and practically more useful version, of the deacons and freedman's Theorem, and analyse in relationship with the predictive viewpoint. Finally we describe a way to combine the two above-mentioned approaches into a unified framework.

description: Research on attitudes towards autonomous vehicles (AVs) shows variation across gender, age, and socio-economic factors. While previous research has emphasized specific features and qualities of AVs, little is known about how attitudinal factors shape AV acceptance across a range of AV “modes” from privately-owned AVs to AV taxis shared with strangers. With an online panel of 834 US-based participants, we examine attitudes towards AVs and sharing. An exploratory factor analysis establishes four attitudinal dimensions: technology acceptance, risk-taking, traffic regulation, and driving enjoyment. We estimate multinomial logistic regression models to examine the impact of these four factors on attitudes toward AVs, willingness to purchase AVs, willingness to use AVs as a taxi service, and willingness to share AV taxis with strangers. We find a complex relationship between psychological factors and AV attitudes. “Early adopters” of technology and those who support stricter traffic regulations are more likely to have a positive attitude about AVs, whereas those who avoid risky behavior were more likely to have a negative attitude instead of a neutral attitude. Similar patterns were found across models of purchasing, using, and sharing AVs. The results imply that people who support traffic regulations may perceive AVs as a safer transport mode than human-driven cars, while those who avoid risk-taking behavior may perceive AVs to be more dangerous. However, we find that a large fraction of the population is not yet ready to use an AV with no driver, and overall reluctance to share a ride in an AV taxi.

description: This paper reports results of a wide empirical study carried out in order to evaluate the design effect components of the Italian labour force survey sampling design. After a brief description of the sampling scheme, we introduce the post-stratified separate ratio estimator of a total and establish an interesting property of self weighting samples. Then we describe the empirical study developed using data from the 1981 demographic census in Umbria. The results concern the contribution of stratification, clustering, systematic selection, and post-stratification to the final design effect in estimating various labour force characteristics. At the end, some comments on the obtained results are given.

description: Gibbons-Fersonts (1985) test of the Capital Asset Pricing Models, which nests the efficient market hypothesis, is implemented on the daily returns of 18 stocks from the Milan Stock Exchange during the period 1.2.1984-2.27.1987. The test is free of Roll's critique and is based on the assumptions of linear-in-the-information-variables expected returns and constant-ratio conditional betas; the empirical results do not reject the CAPM of Black (1972).
Besides the lagged return on the market index is found to be an information variable, while no apparent relationship is detected between monthly and daily dummy variables and the 18 stock returns.

Mena, María Cristina, 1893-1965

description: This article analyzes how Mexican American author María Cristina Mena’s short magazine fiction boldly illustrates the emerging U.S. beauty industry as effectively producing whiteness for sale in the neocolonial marketplace. Her representations of Mexican women’s use of cosmetics articulate how the beauty industry both lends structure to and is structured by the idea of race; at the same time, she reminds her audience that the impact of beauty products and services is in large part determined by the political and economic context of the goods themselves. Through the techniques of role reversals, character development and dramatic irony, Mena’s stories portray the U.S. beauty industry as a dynamic trade that exports new forms of whiteness across its southern border. Far from depicting Mexican women as passive consumers in the neocolonial marketplace, however, Mena shows how beauty products and services can be appropriated as limited yet potent acts of resistance.

description: This research explores the relationship between the use of digital media and stress. Based on the findings of a national, probability sample of adults in the United States, the use of digital media was not directly associated with higher levels of psychological stress. Some uses of digital media were associated with lower levels of perceived stress for women but not for men. However, the evidence suggests that, for men and women, digital media provides heightened awareness of network life events (AoNLE) in the lives of both close and more distant acquaintances. An awareness of undesirable, major life events in the lives of others can be a source of psychological stress; this is the cost of caring. Thus, the link between digital media and stress is indirect. We argue that the growth of digital media is related to changes in the structure of peoples’ personal communities that contribute to this trend. There has been a shift toward networks that offer persistent contact and pervasive awareness. Findings suggest that different mobile technologies, Internet technologies, and social media afford AoNLE for men and women, but women tend to report greater psychological stress than men, and they experience psychological stress from a wider range of AoNLE. We discuss explanations for the negative relationship between technology use and stress for women, as well as the implications of our findings for research on the use of digital media and psychological well-being, such as the relationship to social support, narcissism and empathy.
Galton, Stein and empirical Bayes: artefacts and connections

Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The problem of fallible data ('errors-in-variables') is traced back to Galton's original discovery of 'regression'. Galton's regression is nothing more than the statistical artefact associated with the well known bias of least squares. The interconnections of Galtonts regression, errors-in-variables, Stein-rule estimation, psychometric test theory, least squares, 'permanent income hypothesis', reliability and empirical Bayes are investigated. This essay discusses how a hybrid solution for fallible observation, Stein-rule least squares, can help to improve our understanding of diverse statistical approaches and problems and why the reliability of our data needs to be explicitly incorporated into our empirical estimates.

description: BACKGROUND: Production of cellulosic ethanol is still expensive compared with corn (maize) grain ethanol due to the high costs of bulk production of microbial cellulases. At least three cellulases including endo-cellulase, exo-cellulase and cellobiase are needed to convert cellulosic biomass into fermentable sugars. All these cellulases could be self-produced within cells of transgenic bio-energy crops. The production of heterologous Acidothermus cellulolyticus (E1) endo-cellulase in endoplasmic reticulum and mitochondria of green tissues of transgenic corn plants was recently reported, and it was confirmed that the heterologous E1 converts cellulose into fermentable sugars. RESULTS: Biologically active A. cellulolyticus E1, Trichoderma reesei 1,4-β-cellobiohydrolases I (CBH I) exo-cellulase and bovine rumen Butyrivibrio fibrisolvens cellobiase were expressed in corn plant endoplasmic reticulum (ER), apoplast (cell wall areas) and vacuole respectively. Results show that the ratio 1 : 4 : 1 (E1 : CBH I : cellobiase) of crude heterologous cellulases is ideal for converting ammonia fiber explosion (AFEX) pretreated corn stover into fermentable sugars. CONCLUSIONS: Corn plants that express all three biologically active heterologous cellulases within their cellulosic biomass to facilitate conversion of pretreated corn stover into fermentable sugars is a step forward in the quest for alternatives to the present microbial cellulase mix production for cellulosic biofuels.
Guided crossover: a new operator for genetic algorithm based optimization
Creators: name: Rasheed, Khaled
name: Hirsh, Haym
Publisher: name: Rutgers University
Year: 1998

description: Genetic algorithms (GAs) have been extensively used in different domains as a means of doing global optimization in a simple yet reliable manner. They have a much better chance of getting to global optima than gradient based methods which usually converge to local sub optima. However, GAs have a tendency of getting only moderately close to the optima in a small number of iterations. To get very close to the optima, the GA needs a very large number of iterations. Whereas gradient based optimizers usually get very close to local optima in a relatively small number of iterations. In this paper we describe a new crossover operator which is designed to endow the GA with gradient-like abilities without actually computing any gradients and without sacrificing global optimality. The operator works by using guidance from all members of the GA population to select a direction for exploration. Empirical results in two engineering design domains and across both binary and floating point representations demonstrate that the operator can significantly improve the steady state error of the GA optimizer.

description: Few, if any, regulations over the past decade have received the publicity or engendered the controversy of OSHA’s ergonomics regulation. Some may see the ergonomics rule as the paradigmatic instance of procedural hurdles holding up and eventually destroying a regulation. The purpose of this article is to examine the role that procedure played in the ergonomics rulemaking. To draw lessons from the ergonomics rulemaking I have conducted analyses of the four publicly available versions and conducted interviews with seven high ranking officials at OSHA and the Small Business Administration. I find that of the procedural hurdles faced by OSHA, the notice and comment requirement had the largest impact on the final rule. OMB review and requirements to conduct a cost benefit analysis served largely as a fire alarm to political overseers and the required small business panel had largely symbolic effects. The more traditional control of Congressional budgetary oversight had the greatest effect by delaying the rule for three years which eventually doomed OSHA’s attempts to regulate.
The SLUGGS Survey: Understanding lenticular galaxy formation via extended stellar kinematics

description: We present the latest published and preliminary results from the SLUGGS Survey discussing the formation of lenticular galaxies through analysis of their kinematics. These include a comparison of the measured stellar spin of low-mass lenticular galaxies to the spin of remnant galaxies formed by binary merger simulations to assess whether a merger is a likely formation mechanism for these galaxies. We determine that while a portion of lenticular galaxies have properties consistent with these remnants, others are not, indicating that they are likely faded spirals". We also present a modified version of the spin-ellipticity diagram, which utilises radial tracks to be able to identify galaxies with intermediate-scale discs. Such galaxies often have conflicting morphological classifications, depending on whether photometric or kinematic measurements are used. Finally, we present preliminary results on the total mass density profile slopes of lenticular galaxies to assess trends as lower stellar masses are probed.
Stabilisation of precipitates of pedogenic dissolved organic matter by multivalent cations

description: PurposePrecipitation of dissolved organic matter (DOM) by multivalent cations is important for biogeochemical cycling of organic carbon. We investigated to which extent cation bridges are involved in DOM precipitation and how cross-links by cations and water molecule bridges (WaMB) stabilise the matrix of precipitated DOM.
Materials and methodsDOM was precipitated from the aqueous extract of a forest floor layer adding solutions of Ca(NO3)2, Al(NO3)3 and Pb(NO3)2 with different initial metal cation/C (Me/C) ratios. Precipitates were investigated by differential scanning calorimetry before and after ageing to detect cation bridges, WaMB and restructuring of supramolecular structure.
Results and discussionTwenty-five to sixty-seven per cent of the dissolved organic carbon was precipitated. The precipitation efficiency of cations increased in the order Ca??3 is explained by additional formation of small AlOOH particles. Thermal analysis indicated WaMB and their disruption at T* of 53-65 ˚C. Like cation content, T* increased with increasing Me/C ratio and in the order Ca?ConclusionsOur results suggest a very similar thermal behaviour of OM bound in precipitates compared with soil organic matter and confirms the relevance of WaMB in stabilisation of the supramolecular structure of cation-DOM precipitates. Thus, stabilisation of the supramolecular structure of the DOM precipitates is subjected to dynamics in soils.

description: Statement of problem: Agenesis of the maxillary lateral incisor is linked to differences in overall tooth size. Thus, the mesio-distal space required for final esthetic restoration in patients with missing one of both maxillary lateral incisors may be smaller. Purpose. The purpose of this study is to determine if a tooth size discrepancy exists in orthodontic patients with agenesis of the maxillary lateral incisor(s). Material and methods. Forty sets of dental casts from white orthodontic patients (19 male and 21 female) mean age 15.9 years were collected. All casts had agenesis of one or both maxillary lateral incisors. The teeth were measured with a digital caliper at their greatest mesio-distal width and then compared to a control group matched for ethnicity, age and sex. S One-way repeated measures ANOVA (α=.05) was used for statistical analysis. Results. Males in the test group had significantly smaller maxillary posterior teeth when compared to males in the control group, with differences ranging from 0.28-0.78mm. Females showed significantly smaller maxillary anterior teeth, with differences ranging from 0.22-0.42mm. The remaining maxillary lateral incisor was also significantly smaller (1.27mm difference) in the male and female unilateral agenesis test groups indicating higher incidence of ‘peg’ laterals when compared to the control group. Conclusions. Agenesis of one or both maxillary lateral incisors is associated with a tooth size discrepancy. White males experienced smaller than normal posterior maxillary teeth and females showed smaller anterior maxillary teeth.

description: This presentation was part of the webinar Ageism in the workforce and in the industry at Robert Gordon University, Scotland. 6 April 2021. In this webinar, members of the European Network EuroAgeism provided an in-depth understanding of ageism in the workforce and in the industry by presenting examples of discrimination in the labour market such as discrimination during job interviews and application procedures. More so, they provided examples of how ageism might influence inclusiveness in the organizational environment such as in the case of using and implementing new digital technologies. During the first part of the webinar activities of the whole EUROAGEISM H2020 project in all 15 FIPs/ESRs projects were introduced https://www.rgu.ac.uk/business-innovation/rgu-knowledge-bites-for-business/video-ageism-in-the-workforce-and-in-the-industry

description: ABSTRACT

The isolation and molecular characterization of bacteria are foundational for controlling and improving processes in industries such as dairy, ensuring product safety, quality, and innovation. This study was conducted to isolate and characterize Lactobacillus bulgaricus and Streptococcus thermophilus from commercial milk (fura) hawkers in Maiduguri. The sample was obtained locally from commercial milk (Fura) hawkers in Maiduguri, Borno State, Nigeria. The microbiological analysis of locally fermented milk (Fura) samples revealed that all isolates exhibited distinct colony morphologies and biochemical profiles. Colonies with creamy, shiny appearances were primarily identified as Lactobacillus spp., while whitish, round colonies were associated with Streptococcus spp. Biochemical tests showed that all isolates were positive for carbohydrate fermentation (lactose, maltose, glucose, sucrose, fructose) but negative for indole, citrate, urease, MR, and VP tests. Molecular analysis using PCR further confirmed the presence of Streptococcus thermophilus in three isolates, while eleven isolates were identified as Lactobacillus bulgaricus. The finding of this study aligned with previous research on lactic acid bacteria in traditional dairy products, though differences in bacterial profiles may stem from variations in fermentation methods and environmental conditions. Overall, the findings underscore the necessity of molecular testing for accurate bacterial identification in food production.

description: This study examined the longitudinal association between changes in sugar-sweetened and/or caffeinated beverage consumption and smoking/vaping behaviour among Canadian adolescents. Using longitudinal data from the COMPASS study (2015/16 to 2017/18), four models were developed to investigate whether beverage consumption explained variability in smoking and vaping behaviour in adolescence: (1) smoking initiation, (2) vaping initiation, (3) current smoking status, and (4) current vaping status. Models were adjusted for demographic factors. Multinomial logit models were used for model 1, 2, and 3. A binary logistic regression model was used for model 4. An association between change in frequency of beverage consumption and smoking/vaping behaviour was identified in all models. A one-day increase in beverage consumption was associated with smoking initiation (OR = 1.38, 95% CI: 1.25, 1.51), vaping initiation (OR = 1.23, 95% CI: 1.14, 1.32), identifying as a current smoker (OR = 1.17, 95% CI: 1.01, 1.35), and currently vaping (OR = 1.08, 95% CI: 1.04, 1.11). Change in high-energy drink consumption was the best predictor of smoking behaviours and vaping initiation but not current vaping status. Given the health consequences of smoking and vaping and their association with high-energy drink and coffee consumption, policy initiatives to prevent smoking/vaping initiation, and to limit youth access to these beverages, warrant consideration.

description: In this paper we present a new (slightly more general) formulation of the concept of L-sufficiency due to Rémon (1984) based on a probability measure constructed on partial prior information and on maximized likelihood function. In addition we compare this concept with Kolmogorov's (1942) K-sufficiency.

Vers une classification automatique de didascalies en français avec des grands modèles de langue

description: Suite à nos travaux précédents sur l'affinage de modèles pré-entraînés basés sur BERT pour la même tâche, nous présentons ici des expériences de classification automatique de didascalies en français avec des grands modèles de langue (LLM) sur la base d'une description de leurs types, avec zéro exemples (zero-shot) et avec 20 exemples par classe (few-shot). Nous évaluons des modèles de la famille GPT-4, ainsi que Llama 3.1. Les résultats du modèle gpt-4o (0.7 F1 avec une typologie de 13 classes de nature variée) sont prometteurs. Dans nos expériences, les résultats des LLM sans ou avec peu d'exemples n'atteignent pas les meilleurs scores des modèles BERT affinés sur un volume plus large d'exemples. Cependant, leurs résultats sont intéressants, car une classification de didascalies sans ou avec peu d'exemples permettrait d'annoter de grands corpus (y compris multilingues) avec plusieurs typologies, avec un coût réduit d'annotation manuelle. Une comparaison des analyses selon chaque typologie aiderait à une meilleure compréhension de cet élément complexe, peu étudié avec des méthodes computationnelles.
