Nonlinear estimation of stator winding resistance in a brushless DC motor

Estimation of stator winding resistance in brushless DC motors is important for fault detection and diagnosis. The most popular linear estimation method to date remains the Kalman filter (KF), and the extended form (EKF) for nonlinear systems and measurements. However, a relatively new method referred to as the smooth variable structure filter (SVSF) was introduced in an effort to overcome some of the instability issues with the KF. Further to this development, a new nonlinear estimation strategy was created based on combining elements of the EKF with the SVSF. This new method, referred to as the EK-SVSF, has been applied to a brushless DC motor for estimating the stator winding values. The results are compared with the popular EKF.
University Positioning and Changing Patterns of Doctoral Study: the case of the University of Bath

The study examines the changing nature of doctoral study in higher education in the context of significant global changes in higher education. From its origins with Humboldt, the trajectory of doctoral study is traced through the traditional Ph.D, the extended 'American model', to the professional doctorate. A university case study charts how these global changes impacted on a specific UK university as it attempted to position itself in the changing market for doctoral study.
Heterosis and inbreeding depression in bottlenecked populations: a test in the hermaphroditic freshwater snail Lymnaea stagnalis

Small population size is expected to induce heterosis, due to the random fixation and accumulation of mildly deleterious mutations, whereas within‐population inbreeding depression should decrease due to increased homozygosity. Population bottlenecks, although less effective, may have similar consequences. We tested this hypothesis in the self‐fertile freshwater snail Lymnaea stagnalis, by subjecting experimental populations to a single bottleneck of varied magnitude. Although patterns were not strong, heterosis was significant in the most severely bottlenecked populations, under stressful conditions. This was mainly due to hatching rate, suggesting that early acting and highly deleterious alleles were involved. Although L. stagnalis is a preferential outcrosser, inbreeding depression was very low and showed no clear relationship with bottleneck size. In the less reduced populations, inbreeding depression for hatching success increased under high inbreeding. This may be consistent with the occurence of synergistic epistasis between fitness loci, which may contribute to favour outcrossing in L. stagnalis.
A gene cluster encoding human epidermis-type lipoxygenases at chromosome 17p13.1: cloning, physical mapping, and expression.

Epidermis-type lipoxygenases, a distinct subclass within the multigene family of mammalian lipoxygenases (LOX), comprise recently discovered novel isoenzymes isolated from human and mouse skin including human 15-LOX-2, human and mouse 12R-LOX, mouse 8S-LOX, and mouse e-LOX-3. We have isolated the human homologue of mouse e-LOX-3. The cDNA of 3362 bp encodes a 711-amino-acid protein displaying 89% sequence identity with the mouse protein and exhibiting the same unusual structural feature, i.e., an extra segment of 41 amino acids, which can be located beyond the N-terminal beta-barrel domain at the surface of the C-terminal catalytic domain. The gene encoding e-LOX-3, ALOXE3, was found to be part of a gene cluster of approximately 100 kb on human chromosome 17p13.1 containing in addition the 12R-LOX gene, ALOX12B, the 15-LOX-2 gene, ALOX15B, and a novel 15-LOX pseudogene, ALOX15P. ALOXE3 and ALOX12B are arranged in a head-to-tail fashion separated by 8.5 kb. The genes are split into 15 exons and 14 introns spanning 22 and 15 kb, respectively. ALOX15P was found on the opposite DNA strand directly adjacent to the 3'-untranslated region of ALOX12B. ALOX15B is located in the same orientation 25 kb downstream of ALOX12B, and is composed of 14 exons and 13 introns spanning a total of 9.7 kb of genomic sequence. RT-PCR analysis demonstrated a predominant expression of ALOXE3, ALOX12B, and ALOX15B in skin.
Sexuality, Power and Resistance in the Workplace

This paper investigates whether the expression of sexuality in organizations represents an opportunity for employee resistance or increased management control. It draws upon an empirical study of a high-commitment culture programme that encouraged both heterosexual and homosexual discourses. The study reveals a complex scenario in which sexuality is simultaneously a facet of control, a site of empowerment and an object of resistance. It is suggested that a multilevelled conceptualization of power and resistance is required in order to untangle the complex political implications of sexuality and re-eroticization at work.
Introduction

“Family migration” and “integration” are intimately related concepts in policy discourses in Europe today. Assumptions about the relation between “family migration” and “integration” play a crucial role in shaping policies. This special issue aims to examine the axis between “family migration,” “policy,” and “integration,” both from a policy perspective, and from the perspective of individuals engaged in family migration. In this introduction, we first discuss scholarly work on family migration policies in Europe, which analyzes how policies and discourses on family migration and integration participate in the politics of belonging. Second, we explore the fragmented and incomplete insights offered by existing research about the actual relation between family migration and migrant integration.
Promoting Student Achievement With Integrated Affective Objectives

In contrast to the perception that the low graduation rates in the SMET (Science, Mathematics, Engineering, and Technology) disciplines are a result of a “normal weed-out process,” studies show that large percentages of students are capable but choose not to persist, while others despite their dissatisfaction persist to graduation. 14, 30, 27, 29 Primary reasons for dissatisfaction and departure include non-sustained student interest in the discipline and a lack of the sense of belonging. 14, 30, 32 Moreover, affective measures have been shown to be better indicators of early student departure. 33 For students who do persist to graduation, dissatisfaction negatively affects employee qualities identified by ABET and the National Association of Colleges and Employers (NACE 2001). 1 Most of these factors, such as honesty/integrity, teamwork skills, interpersonal skills, motivation/initiative, strong work ethic, flexibility/adaptability, and self-confidence, fall into the affective domain. Because the development of affective qualities has been correlated with student achievement, the aim of affective efforts need not be on retaining students, but rather on student achievement and retention will naturally follow. 30 The fact that student interest, belonging, motivation, and most of the NACE qualities are affective in nature suggests that an organized approach to foster appropriate affective growth could favorably impact student success in SMET disciplines. Standard levels of affective growth have been defined in Krathwohl’s affective taxonomy: receiving, responding, valuing, organizing, and characterization. 13 This paper recommends the integration of discipline-based affective objectives into curricula to enliven, incorporate, and sustain the energy of students in order to attain higher cognitive and affective achievement. Our experience has centered on the freshmen problem-solving and programming sequence in the School of Computer and Information Science at our medium-size, state university. We anticipate that this approach is widely applicable throughout our curriculum and is adaptable to other SMET disciplines. We began with the freshman year, because national and local data indicate that the majority of students leave SMET disciplines and college as well by the end of their freshman year. 29, 30 Integrated with cognitive objectives, affective objectives served to provide higher quality cognitive experiences for students and served to retain students who might otherwise have left the discipline for reasons other than academic difficulty. Building on prior work, our enhanced approach began with the definition and integration of specific affective objectives which supported the internalization of cognitive objectives and professional practices. Affective-cognitive growth was pursued through methodologies which included active and cooperative learning, student self-reflection, classroom discussion, and student incorporation into
Perceptions of teachers of students with visual impairments on the importance of physical activity and its effect on their students' academic success and social interactions

More than 60% of the adult population in the United States is overweight, and obesity has reached epidemic proportions in this country. Childhood obesity has more than doubled since 1990, and the health consequences are reflected in the rising cost of health care. There has also been a significant drop in physical activity across the country and physical education is no longer required in middle schools. The lack of physical activity and issues of weight can compromise the ability of the individual who is blind or visually impaired to maneuver through the environment safely and efficiently. The purpose of this study was to examine the perceptions of itinerant teachers of students with visual impairments about the importance of physical activity for their students with visual impairments and its effect on academic success and social relationship. Data was gathered from 175 teachers of students with visual impairments concerning their perceptions regarding the importance of physical activity and obesity and their relationship with academic success and social relationships. The teachers indicated that physical activity for their students is very important. They described a multitude of barriers that account for a lack of involvement in the general physical education classes in which they were enrolled. Teachers reported on their own personal physical activity levels in relationship to the importance they placed on their students’ need to be active. The teachers did not indicate that being overweight was a particular issue with their visually impaired students, but they acknowledged that being overweight
INITIAL MENTAL DISORDERS IN CARCINOMA OF PANCREAS AND STOMACH

There are several casuistic reports of early mental disorders in carcinoma of the pancreas (c.P.) usually in the form of depression, anxiety and insomnia. These have resulted in psychiatric diagnoses such as involutional depression, psychoneurosis or psychosomatic disorders, and treatment with electroconvulsive therapy, pharmacotherapy or psychotherapy has sometimes been temporarily successful (Yask in 193 1, Cabot 1932, Latter & Wilbur 1937, Rickels 1945, Kant 1946, Pelner 1947, With 1953, Savage & Noble 1954, Karliner 1956, Perlas & Faillace 1964, Bratfos 1966). In retrospectively investigated series of c.p. there is usually a fairly high percentage of cases with initial mental disturbance without or coiicurrent with somatic symptoms such as pain and loss of weight. In the latter cases the mental complaints were often considered to be out of proportion to the meagre physical finding. Eusterman & Wilbur (1933) found 8 out of 88 cases of c.p. with nervousness or general decline in health as outstanding early symptoms. Ulett & Pavsons (1948) in a series of 87 cases report 9 who presented a psychiatric problem of some importance. The psychiatric syndrome consisted of depression, agitation and intractable insomnia coinciding with rather vague abdominal discomfort which in itself could not reasonbly account for the mental symptoms. Savage, Butcher & Noble (1952) had 5 out of 20 patients with complaints which despite the presence of pain and loss of weight were considered as "functional". In other surveys nervous manifestations were less common (Levy & Lichtman 1940, Storm Mathisen 1950, Thamsen et al. 1950, Birnbaum & Kleeberg 1958). The only prospective investigation so far published is by Fras, Lit in & Pearson (1967) who compared c.p. with carcinoma of the colon. Using clinical examination, an inventory and ratings before the establishment of the diagnosis, they found that 22 out of the 46 patients with C.P. had
The escalatory Red Queen: Population extinction and replacement following arms race dynamics in poplar rust

Host–parasite systems provide convincing examples of Red Queen co‐evolutionary dynamics. Yet, a key process underscored in Van Valen's theory – that arms race dynamics can result in extinction – has never been documented. One reason for this may be that most sampling designs lack the breadth needed to illuminate the rapid pace of adaptation by pathogen populations. In this study, we used a 25‐year temporal sampling to decipher the demographic history of a plant pathogen: the poplar rust fungus, Melampsora larici‐populina. A major adaptive event occurred in 1994 with the breakdown of R7 resistance carried by several poplar cultivars widely planted in Western Europe since 1982. The corresponding virulence rapidly spread in M. larici‐populina populations and nearly reached fixation in northern France, even on susceptible hosts. Using both temporal records of virulence profiles and temporal population genetic data, our analyses revealed that (i) R7 resistance breakdown resulted in the emergence of a unique and homogeneous genetic group, the so‐called cultivated population, which predominated in northern France for about 20 years, (ii) selection for Vir7 individuals brought with it multiple other virulence types via hitchhiking, resulting in an overall increase in the population‐wide number of virulence types and (iii) – above all – the emergence of the cultivated population superseded the initial population which predominated at the same place before R7 resistance breakdown. Our temporal analysis illustrates how antagonistic co‐evolution can lead to population extinction and replacement, hence providing direct evidence for the escalation process which is at the core of Red Queen dynamics.
Low prevalence of atopy in young Danish farmers and farming students born and raised on a farm

Background Recent studies have shown that in several countries atopic sensitization to common allergens (common atopy) and atopic symptoms are markedly less prevalent in children living on a farm, compared with non‐farm children living in the same rural areas. Living conditions on farms may, however, vary largely between different countries. It is also not yet known whether the ‘protective’ effect of a farm environment can also be found in adults.
Vigorous Physical Activity Among College Students: Using the Health Belief Model to Assess Involvement and Social Support

Objectives: The purpose of this study was to examine college students’ perceived benefits, barriers, cues to action, and extent of involvement in vigorous physical activity. Methods : A convenience sample of 480 participants (92% response rate) was surveyed at a Midwestern university. Valid and reliable subscales were developed for the 21-item questionnaire. Analyses were conducted to examine whether benefits, barriers, cues, and vigorous physical activity involvement differed significantly based on: sex, grade level, parental exercise patterns, parental encouragement, peer exercise patterns, and peer encouragement . Results: Results indicated that participants’ involvement in vigorous physical activity each week was on average 2.36 days. Parent and peer involvement in and encouragement of vigorous physical activity significantly affected the number of perceived benefits, barriers, cues and involvement in vigorous physical activity. Results showed significant correlations between the number of perceived benefits, barriers, cues to action, and the extent of involvement in vigorous physical activity. Conclusions: The number of perceived benefits and cues to exercise was associated with higher vigorous physical activity involvement, while the number of perceived barriers was associated with lower vigorous physical activity involvement. Such results should be considered when developing and implementing strategies aimed at increasing vigorous physical activity among students.
Posttraumatic residues of captivity: a follow-up of Israeli ex-prisoners of war.

BACKGROUND This article examines the long-term impact of wartime captivity. METHOD One hundred sixty-four prisoners of war (POWs) and 189 matched combatants of the 1973 Yom Kippur War filled out a series of questionnaires that assessed posttraumatic stress disorder (PTSD), general psychiatric symptomatology, and social functioning according to DSM-III-R criteria. RESULTS Almost 2 decades after the war, ex-POWs exhibited higher rates and greater intensity of posttraumatic stress reactions, more general psychiatric symptomatology, and more severe problems in functioning at home, at work, and in the military than did the control group (Israeli veterans who were not POWs). They were also more likely to obtain official disability recognition and to seek psychological help. Their recovery was slower and professional help less effective. In addition, the veterans with PTSD in both groups had high rates of comorbid general psychiatric symptomatology. CONCLUSION These findings point to the depth, range, and persistence of the stress residuals of wartime captivity.
Postmortem Brain Levels of Urate and Precursors in Parkinson's Disease and Related Disorders

Background: Increasing evidence suggests that urate may play an important role in neurodegenerative disease. In Parkinson's disease (PD) higher, but still normal, levels of blood and cerebrospinal fluid urate have been associated with a lower rate of disease progression. Objective: We explored the hypothesis that lower levels of urate and its purine precursors in brain may be associated with PD and related neurodegenerative disorders, including Alzheimer's disease (AD) and Lewy body dementia (DLB). Methods: Human postmortem brain tissues were obtained from PD, AD, and DLB patients and non-neurodegenerative disease controls. We measured urate and other purine pathway analytes in the frontal and temporal cortex, striatum, and cerebellum, using high-performance liquid chromatography with electrochemical and ultraviolet detection. Results: Age was well-matched among groups. Mean postmortem interval for samples was 16.3 ± 9.9 h. Urate levels in cortical and striatal tissue trended lower in PD and AD compared to controls in males only. These findings correlated with increased urate in male versus female control tissues. By contrast, in DLB urate levels were significantly elevated relative to PD and AD. Measurement of urate precursors suggested a decrease in xanthine in PD compared to AD in females only, and relative increases in inosine and adenosine in DLB and AD samples among males. Xanthine and hypoxanthine were more concentrated in striatal tissue than in other brain regions. Conclusions: Though limited in sample size, these findings lend support to the inverse association between urate levels and PD, as well as possibly AD. The finding of increased urate in DLB brain tissue is novel and warrants further study.
Kallikrein gene delivery attenuates hypertension and cardiac hypertrophy and enhances renal function in Goldblatt hypertensive rats.

To demonstrate potential therapeutic effects of kallikrein gene delivery, we delivered adenovirus (Ad.CMV-cHK) carrying the human tissue kallikrein gene into two-kidney, one-clip Goldblatt hypertensive rats. A single intravenous injection of the recombinant adenovirus caused a delay of blood pressure increase that began 1 day after injection and continued for 24 days. A maximal blood pressure reduction was observed in rats receiving kallikrein gene delivery compared with control rats receiving Ad.CMV-LacZ (160+/-5 versus 186+/-7 mm Hg, n=6, P<.01). The expression of human tissue kallikrein mRNA was identified in the kidney, heart, aorta, and liver of rats receiving kallikrein gene delivery. Immunoreactive human kallikrein levels were measured in rat serum and urine in a time-dependent manner. Adenovirus-mediated kallikrein gene delivery caused a significant reduction in the left ventricular mass and cardiomyocyte size, as well as an increase in renal blood flow, urine flow, glomerular filtration rates, electrolyte output, and urine excretion. Enhanced renal responses were accompanied by significant increases in urinary kinin, nitrite/nitrate, and cyclic GMP levels. These findings show that the expression of human tissue kallikrein via gene delivery has protective effects against renovascular hypertension and cardiovascular and renal dysfunction.
Integrating Children’s Human Rights and Child Poverty Debates: Examples from Young Lives in Ethiopia and India

There are few attempts to link human rights discourses and child poverty debates, though the field is expanding. Within sociology, both the study of rights and of childhood are marginal. This article utilises a sociological approach to bridge rights and poverty debates in relation to children and explore why there are barriers to implementing children’s rights in specific instances. Drawing on Young Lives research, a longitudinal study of children growing up in poverty, the article explores how discourses of children’s rights play out in local contexts and how a narrowly legal perspective fails to engage with children’s experiences of poverty. The article concludes by proposing that a broader, sociological approach to rights as not only rules, but also as structures, relationships and processes (Galant and Parlevliet, 2005) can better engage with the causes and consequences of poverty, while also developing locally relevant responses.
CUNY Academic Works

We have used this space to discuss some of the ways to organize research, in terms of both bibliographic management and bookmarks (Ovadia, 2011, 2012). Perhaps just as important is the need to capture notes and ideas as one is conducting research. While physical notebooks and locally saved electronic ﬁles are certainly helpful, there are a number of web-based solutions that might be useful to someone conducting research online
Do-it-yourself: An online positive psychology intervention to promote positive emotions, self-efficacy, and engagement at work.

Purpose – The purpose of this paper is to investigate the effects of an individual oriented positive psychology intervention on positive emotions, self‐efficacy, and work engagement. Design/methodology/approach – The online self‐enhancement intervention program consists of three types of online assignments: happiness assignments, goal setting assignments, and resource building assignments. The authors expected the self‐enhancement intervention group to show a significantly stronger increase in the outcome variables compared to a self‐monitoring control group. Findings – The results revealed that the self‐enhancement group showed a stronger increase in positive emotions and self‐efficacy compared to the control group, but not on engagement. Additional analyses showed that the positive effects of the self‐enhancement intervention are present for employees who are initially low in engagement, but not for those medium or high in engagement. Research limitations/implications – The study was conducted via a semi‐public web site. The participants were all working in different organizations throughout the country and did not have the advantage of having the support of their supervisors and colleagues who were participating in a similar intervention. Practical implications – Positive psychology interventions should target employees who are low in engagement, because they have the most unused potential and therefore have more to gain. Originality/value – Traditionally speaking, individual interventions are carried out when something is wrong or malfunctioning, and with the sole objective of fixing it. The intervention presented in this paper includes the entire workforce, because it is based on the belief that improving employee well‐being is relevant for all.
