Abilities that distinguish the effectiveness of five‐year alumna performance across work, family and civic roles: a higher education validation

This study demonstrates how academic faculty members are able to connect an undergraduate liberal arts and professions curriculum with the demonstrated performance of multidimensional and complex abilities by five‐year alumnae in professional, civic and family contexts. Alumna abilities scored by researchers were statistically correlated with independent judgments by faculty members of the overall effectiveness of the same alumna performances. Thematic analysis of faculty members' descriptions of the bases of their judgments added to the picture of what types of abilities connect higher education outcomes most strongly with effective alumna performance. Triangulated findings confirmed that a wide range of intellectual, prosocial, independent, and team‐oriented abilities are related to effective alumna performance. From a faculty perspective, effective alumna performance was broadly grounded in the breadth of the frameworks used for constructing action, the flexible use of disciplinary knowledge, a skilled collaboration with others, and a mature capacity for self assessment of one's performance and abilities. The findings and methods have implications for how the ideals of academic faculty can be included in a grounded dialogue with employers and wider publics about the goals and outcomes of higher education.
THE CONTROL OF BIOMASS PARTITIONING IN PLANTS FROM “ FAVOURABLE ” AND “ STRESSFUL ” ENVIRONMENTS : A ROLE FOR GIBBERELLINS AND CYTOKININS

Plants which naturally occur on nutrient-poor sites have inherently lower growth rates when compared to plants from more favourable habitats. This difference in growth rate is maintained when the species are compared under conditions which are optimal for their growth. Genetic variation in plant growth rate is predominantly due to variation in the pattern of biomass allocation in leaves, stems and roots: fast-growing genotypes have more leaf area per unit plant weight, but the leaves have a low biomass density. Gibberellins are involved in some of these inherent differences in biomass allocation. Under nitrogen-stress, i.e. when exposed to nitrogen-poor conditions, a plant's growth rate is reduced, when compared to that at an optimum supply of nutrients. This is partly accounted for by a smaller investment of resources in leaves and a greater investment in roots. Rates of photosynthesis per unit leaf area may also be less at a growth-limiting supply of nitrogen, whereas carbon requirements for respiration, expressed as a proportion of carbon fixed in photosynthesis, are increased. This is largely due to increased carbon requirements for root respiration, due to the relative increase in size of the root system. Under nitrogen-stress, the leaves of inherently fast-growing as well as those of slow-growing Poa species accumulate less protein and more cell-wall components. This is associated with an increase in leaf mass per unit leaf area and a relatively greater investment in sclerenchymatic cells. The volume occupied by epidermal cells is reduced, despite their relative increase in number, due to the decrease in epidermal cell size. Cytokinins play a major role in the shift in biomass allocation from leaves to roots, as BULG. 25 dependent on nitrogen supply. There is no information to support a role of cytokinins in the changes in leaf anatomy. This paper reviews recent information on the mechanisms accounting for the pattern of biomass allocation between leaves and roots. The role of gibberellins and cytokinins in the control of biomass allocation is also discussed. We conclude that gibberellins account for part of the genotypic variation in biomass allocation, whereas cytokinins are responsible for part of the phenotypic changes upon nitrogen-stress.
Lie detection during high‐stakes truths and lies

Purpose The current study seeks to expand the deception detection literature by using real-world pre-interrogative interviews to discern differences in how novices (students) versus experts (police officers) make judgments about truths and lies. Methods Videotapes of routine traffic stops depicting either liars (incriminating evidence was found in the car) or truth-tellers (no evidence was found in the car) were edited so the final car search was cut out. Novices and experts watched the tapes and made truth or lie judgments about the subject in each video. Results Overall accuracy of detecting truths and lies for students was 63%, while overall accuracy for police was 60%. The difference between the groups was not significant. These results were then compared with previously published rates (Bond & DePaulo, 2006). Students' overall accuracy rates in this study were higher than previously published accuracy rates. However, police officers' accuracy rates were not higher than previously published accuracy rates. Conclusions Realistic stimulus materials seem to increase overall accuracy rates for students. However, despite differences in experience, there was no difference between novice and expert truth and lie accuracy.
Transactive memory systems scale for couples: development and validation

People in romantic relationships can develop shared memory systems by pooling their cognitive resources, allowing each person access to more information but with less cognitive effort. Research examining such memory systems in romantic couples largely focuses on remembering word lists or performing lab-based tasks, but these types of activities do not capture the processes underlying couples’ transactive memory systems, and may not be representative of the ways in which romantic couples use their shared memory systems in everyday life. We adapted an existing measure of transactive memory systems for use with romantic couples (TMSS-C), and conducted an initial validation study. In total, 397 participants who each identified as being a member of a romantic relationship of at least 3 months duration completed the study. The data provided a good fit to the anticipated three-factor structure of the components of couples’ transactive memory systems (specialization, credibility and coordination), and there was reasonable evidence of both convergent and divergent validity, as well as strong evidence of test–retest reliability across a 2-week period. The TMSS-C provides a valuable tool that can quickly and easily capture the underlying components of romantic couples’ transactive memory systems. It has potential to help us better understand this intriguing feature of romantic relationships, and how shared memory systems might be associated with other important features of romantic relationships.
Autoimmune hepatitis among fertile women: Strategies during pregnancy and breastfeeding?

Objective. In published studies there is a lack of data about the risks, management and how women with autoimmune hepatitis (AIH) decide on and are advised about pregnancy. The aim of this study was to investigate how women with AIH consider pregnancies, are advised and pharmacologically treated, as well as the outcome. Material and methods. A questionnaire was mailed to 128 women with AIH diagnosed during their fertile period and data from the Swedish National Birth Register was also used for matched controls. Results. There was an 83% response rate to the questionnaires. Sixty-three pregnancies were reported by 35 women. 48% did not consult their doctors before getting pregnant. More than half of the women reduced or stopped the immune suppression during pregnancy or breastfeeding. Some women were advised to abstain from pregnancy or even to have an abortion. Caesarean sections were performed more frequently in the AIH group (16% compared with 6.5% in the control group p<0.01). There were no significant differences in the number of stillborn infants or infants with malformations. However, 30% of the patients experienced flare-up after delivery. Conclusions. In general, the outcome of pregnancy in women with AIH seems to be good. Current pharmacological treatment appears to be safe, including azathioprine during pregnancy and lactation. After delivery an active preparedness to increase pharmacotherapy should be considered.
Greedy algorithms for pure pixels identification in hyperspectral unmixing: A multiple-measurement vector viewpoint

This paper studies a multiple-measurement vector (MMV)-based sparse regression approach to blind hyperspectral un-mixing. In general, sparse regression requires a dictionary. The considered approach uses the measured hyperspectral data as the dictionary, thereby intending to represent the whole measured data using the fewest number of measured hyperspectral vectors. We tackle this self-dictionary MMV (SD-MMV) approach using greedy pursuit. It is shown that the resulting greedy algorithms are identical or very similar to some representative pure pixels identification algorithms, such as vertex component analysis. Hence, our study provides a new dimension on understanding and interpreting pure pixels identification methods. We also prove that in the noiseless case, the greedy SD-MMV algorithms guarantee perfect identification of pure pixels when the pure pixel assumption holds.
Worth a Glance: Using Eye Movements to Investigate the Cognitive Neuroscience of Memory

Results of several investigations indicate that eye movements can reveal memory for elements of previous experience. These effects of memory on eye movement behavior can emerge very rapidly, changing the efficiency and even the nature of visual processing without appealing to verbal reports and without requiring conscious recollection. This aspect of eye movement based memory investigations is particularly useful when eye movement methods are used with special populations (e.g., young children, elderly individuals, and patients with severe amnesia), and also permits use of comparable paradigms in animals and humans, helping to bridge different memory literatures and permitting cross-species generalizations. Unique characteristics of eye movement methods have produced findings that challenge long-held views about the nature of memory, its organization in the brain, and its failures in special populations. Recently, eye movement methods have been successfully combined with neuroimaging techniques such as fMRI, single-unit recording, and magnetoencephalography, permitting more sophisticated investigations of memory. Ultimately, combined use of eye-tracking with neuropsychological and neuroimaging methods promises to provide a more comprehensive account of brain–behavior relationships and adheres to the “converging evidence” approach to cognitive neuroscience.
The association between working hours and sleep disturbances according to occupation and gender

We attempted to explore the relationship between working hours and sleep disturbance according to occupation and gender among Korean workers. Data were derived from the third Korean Working Conditions Survey, conducted in 2011 by the Korea Occupational Safety and Health Agency. From a total of 50 032 workers, 34 783 salaried contract workers were selected. Work hours were categorized as <40, 40–48 (reference), 49–60, and >60 h/week. The outcome variable was sleep disturbance, which was assessed by a single question item (During the past 12 months, have you experienced sleep disturbance or insomnia? ). Multiple survey logistic regression models were performed after adjusting with age, education level, marital status, self-rated health, salary, shift work, smoking and alcohol drinking. Gender and occupation were stratified in these models. The adjusted odds ratio (OR) for sleep disturbance in male non-manual workers with long work hours (>60 h/week) was 3.017 [95% confidence interval (CI) 1.956–4.653]. In female non-manual workers who work 49–60 working hour per week, the OR was 1.525 (95% CI 1.034–2.249). Long working hours can be a risk factor for sleep disturbance in Korean workers. The association was especially prominent in male non-manual workers.
The Antillese in France: Trends and prospects

The cultural drives in the Antillese population in continental France have switched, in step with migration dynamics, in direction and target: they focus less than in the past on the future of the ‘native lands’ and more on improved integration in the host country. But in such a situation, facing racism, Antillese peoples in France are paradoxically reduced to emphasizing their collective identity, notably through associations, to obtain recognition from the host society’s institutions and achieve social advancement within that society. A recognition of the diversity and complexity of the cultural dynamics in question should lead to break with any essentialist thinking and, then, to reappraise many of the ideas that are at the heart of the discussions inspired by those dynamics, notably the idea of diaspora.
Business process management: a maturity assessment of Saudi Arabian organizations

Purpose – Business Process Management (BPM) has become increasingly common among organizations in different industries. There is very limited research on the application of BPM in the MENA region and particularly in Saudi Arabia. The purpose of this paper is to provide empirical maturity assessment for selected Saudi Arabian organizations from broad range of industries. Findings showed that there is notable variability of BPM perception within the functional groups of the sample organizations. Organizations with holistic business strategy and resilient change management procedures showed more adherence to BPM practices than those with functionally driven or ad-hoc BPM initiatives. Design/methodology/approach – In this empirical study, structured interviews were undertaken with selected business functions owners from ten Saudi organizations. All selected organizations resides in the city of Riyadh with most of them having local and regional branches. The selection of the organization followed non-probability sampling technique whereby the selected organizations were those seemed easy to access and showed willingness to participate in the research. The sample organizations included different types of businesses in different industries. Even though the purpose of the study is not applicable to a particular industry type or sector, variety of business domains and variability in organizations size were considered in the selection process. Table 1 shows an overview of the organization business sector. Findings – This research investigates the current status of BPM implementation among Saudi Arabian organizations. Although there is positive favour towards BPM concepts among Saudi organizations, it seems that the practical understanding of BPM is yet to be matured. One of the noticed findings from the survey is the apparent sharp disjoint between information technology (IT) and business strategy. This segregation, from a BPM perspective, created two variants of BPM understanding; a business variant related to designing and managing business operations, and the IT one which focusses on configuring and installing BPM systems. There is a lack of a holistic view of business processes and its associated activities within an organization. Most surveyed organizations have either no clear business strategy or it is too complicated the thing that make it difficult to integrate it with BPM initiatives. Some organizations have no defined process owners for their main core business processes neither there are measurable goals for their performance. Their main BPM endeavour is mainly focused on the process activities rather than the process output and performance. Originality/value – This is the first research paper that provides empirical research on the status of BPM in the MENA region and particularly in Saudi Arabia.
Impact of Glutathione S-Transferase M1 and T1 Gene Polymorphisms on the Smoking-Related Coronary Artery Disease

Glutathione S-transferase (GST) plays a key role in the detoxification of xenobiotic atherogen generated by smoking. To analyze the effect of GSTM1/T1 gene polymorphisms on the development of smoking-related coronary artery disease (CAD), 775 Korean patients who underwent coronary angiography were enrolled. The subjects were classified by luminal diameter stenosis into group A (>50%), B (20-50%), or C (<20%). GSTM1 and GSTT1 gene polymorphisms were analyzed using multiplex polymerase chain reaction (PCR) for GSTM1/T1 genes and CYP1A1 gene for internal control. Of 775 subjects, 403 patients belonged to group A. They had higher risk factors for CAD than group B (N=260) and group C (N=112). The genotype frequencies of null GSTM1 and GSTT1 showed no significant differences among 3 groups. Considering the effect of GSTM1 gene polymorphisms on the smoking-related CAD, smokers with GSTM1 null genotype had more increased risk for CAD than non-smoker with GSTM1 positive genotype (odds ratios [OR], 2.07, confidence interval [CI], 1.06-4.07). Also the effect of GSTT1 gene polymorphism on smoking-related CAD showed the same tendency as GSTM1 gene (OR, 2.00, CI, 1.05-3.84). This effect of GSTM1/T1 null genotype on smoking-related CAD was augmented when both gene polymorphisms were considered simultaneously (OR, 2.76, CI, 1.17-6.52). We concluded that GSTM1/T1 null genotype contributed to the pathogenesis of smoking-related CAD to some degree.
Endothelins, peptides with potent vasoactive properties, are produced by human macrophages

Endothelins are peptides, originally isolated from endothelial cells, with potent vasoactive and mitogenic properties. In this study, we demonstrate that human macrophages synthesize and secrete endothelins. Cultured human macrophages were found by immunocytochemistry to stain positively for endothelin 1 and endothelin 3. Their capability to produce and release these peptides was confirmed by a combination of reverse-phase high-performance liquid chromatography and radioimmunoassays, specific for endothelin 1 and 3, respectively. Immunoreactive peptides were identified both in cellular extracts and in macrophage-conditioned medium. The secretion of endothelin 1, but not of endothelin 3, from macrophages could be stimulated 6-10-fold by lipopolysaccharide or phorbol myristate acetate (PMA). Northern blot analysis of total macrophage RNA using an endothelin 1 cDNA probe revealed induction of endothelin mRNA in PMA-treated macrophages. Furthermore, immunoreactive endothelin 1 and 3 were found in U937 cells, a human promonocytic line, and in freshly isolated human monocytes. In contrast, no immunoreactive endothelin was detected in cell extracts from human neutrophils and lymphocytes. The expression of endothelins in tissue macrophages was demonstrated in paraffin sections of human lung using immunohistochemistry. In conclusion, the finding that human macrophages produce endothelins suggests an important role for these peptides in the microenvironment of tissue macrophages. Macrophage-derived endothelins may have an essential function in blood vessel physiology, and aberrant production may contribute to vessel pathology.
An analysis of cumulative lifetime solar ultraviolet radiation exposure and the benefits of daily sun protection

Cumulative exposure to ultraviolet radiation (UVR) increases the risk of developing skin cancer, particularly squamous cell carcinoma and basal cell carcinoma. Thus, the need for protection from the sun is widely advocated, but consumers generally associate such protection with the occasional extreme exposure and tend to ignore the risk of long-term exposure. In fact, a sun exposure model predicts that over a lifetime, a person will receive tens of thousands of minimal erythema doses worth of UVR through normal, daily, incidental exposure. The cumulative effect of casual sun exposure over the years underscores the need for everyday basic UVR protection in which even low level (SPF 4–10) sunscreens are shown to offer significant benefit. Analysis shows that daily protection can reduce lifetime exposure by 50% or more.
The antioxidant and cytotoxic activities of Sonchus oleraceus L. extracts

This study investigated in vitro antioxidant activity of Sonchus oleraceus L. by extraction solvent, which were examined by reducing power, hydroxyl radical-scavenging activity(HRSA) and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assays. 70% MeOH extract had the greatest reducing power while EtOH extract had the greatest HRSA. The antioxidant activity of S. oleraceus extracts was concentration dependent and its IC50 values ranged from 47.1 to 210.5 µg/ml and IC50 of 70% MeOH, boiling water and 70% EtOH extracts were 47.1, 52.7 and 56.5 µg/ml, respectively. 70% MeOH extract of S. oleraceus contained the greatest amount of both phenolic and flavonoid contents. The extracts tested had greater nitrite scavenging effects at lower pH conditions. The cytotoxic activity showed that EtOH extract had the best activity against the growth of stomach cancer cell. These results suggest that S. oleraceus extract could be used as a potential source of natural antioxidants.
The ultrastructure and ontogeny of pollen in Helleborus foetidus L. IV. Pollen grain maturation.

The final stages of Helleborus pollen-grain ontogeny, which culminate in maturation and germination of the grain, have been investigated at the ultrastructural level. Following the deposition of primary and secondary exine, and during the early stages of intine formation, the microspore passes through a vacuolate phase, in which the cytoplasm appears devoid of most organelles other than the prominent nucleus. The formation of the vacuole results in the displacement of the nucleus to one side of the pollen grain. The vacuole quickly disappears and a number of organelles reappear in the cytoplasm, in particular the dictyosomes and strands of endoplasmic reticulum, with associated grey bodies. Following mitotic division of the pollen grain, the first signs of the generative cell wall appear as a pair of tightly appressed unit membranes in the narrow strand of cytoplasm separating the two newly formed generative and vegetative nuclei. As development proceeds, the space between the two membranes gradually fills with an electron-transparent material similar to the substance found in the numerous dictyosome-derived vesicles which, together with the endoplasmic reticulum, are both closely associated with the developing cell wall. The generative cell wall fuses with the cellulosic intine, which has gradually increased in amount during these stages, and the cell division is complete. The smaller generative cell contains a prominent nucleus and a small amount of cytoplasm devoid of plastids and most other organelles. The larger vegetative cell also contains a prominent nucleus and a large amount of cytoplasm containing amyloplasts, mitochondria, dictyosomes and endoplasmic reticulum, and abundant ribosomes, many of which are in a polysome configuration. The final stages in development are characterized by a progressive decrease in the amount of starch in the vegetative cell and an increase in the size of grey bodies, many of which are invested in multilayered shrouds of endoplasmic reticulum. The generative cell wall disappears and a multivesicular/granular body gradually appears at the periphery of the pollen grain. The granular-vesicular material, which is formed from the dictyosomes and/or the degenerating plastids, is thought to represent metabolic reserves necessary for pollen-tube formation. One or more pollen tubes emerge from the apertural sectors of the pollen grain, and maturation of the grain is complete.
