Learning and development experiences of self-initiated expatriate women in the United Arab Emirates

The article explores self-initiated expatriate women's experiences of working and learning in the United Arab Emirates (UAE). Adler's (Adler, N. 1987. Pacific basin managers: A Gaijin, not a woman. Human Resource Management 26, no. 2: 169–91) seminal study and Tung's (Tung, R.L. 2004. Female expatriates: The model of the global manager. Organizational Dynamics 33: 243–53) research suggest that expatriate women operating in a foreign host culture are categorized as a ‘Third Gender’: host nationals would perceive them as ‘foreign’ first and ‘women’ second, consequently according them different privileged treatment inworkplaces than host national women colleagues. This qualitative study of self-initiated expatriate women highlights how the women's constructions of themselves as ‘foreign’ and ‘female’ in the UAE provide a lens through which they reflect upon their own experiences of learning and development. In the absence of support from their own organizations and/or driven by their own aspirations, the women embarked upon their professional development initiatives; networking, coaching and formal qualifications. Key themes of vulnerability in being a foreigner, gendered workplaces, informal learning and women's agency in their own learning and development emerge from the analysis. The women's experiences suggest that their ‘Third Gender’ identity frames both constraints and opportunities within their social and work environment. The research focus on self-initiated expatriate women developing their professional practice, without the organizational Human Resource Development (HRD) support normally provided for assigned expatriates, is a key contribution to HRD, expatriate and international management literature where gender has tended to be ignored.
How brand image, country of origin, and self-congruity influence Internet users’ purchase intention

In this study we explored the influence of country of origin (COO), brand image, and self-congruity on consumers’ purchase intention of luxury brands via the Internet. We found that: (a) consistency in the country of origin (COO), self-congruity, and brand image had a positive impact on purchase intention; (b) inconsistency between the country of brand and the country of manufacture, and consistency in the country image increased the influence of brand image on purchase intention when the brand image was weak; (c) inconsistency in the country image decreased the influence of brand image on purchase intention when the brand image was weak; and (d) consistency in COO influenced purchase intention more strongly than did self-congruity.
Anc1, a Protein Associated with Multiple Transcription Complexes, Is Involved in Postreplication Repair Pathway in S. cerevisiae

Yeast strains lacking Anc1, a member of the YEATS protein family, are sensitive to several DNA damaging agents. The YEATS family includes two human genes that are common fusion partners with MLL in human acute leukemias. Anc1 is a member of seven multi-protein complexes involved in transcription, and the damage sensitivity observed in anc1Δ cells is mirrored in strains deleted for some other non-essential members of several of these complexes. Here we show that ANC1 is in the same epistasis group as SRS2 and RAD5, members of the postreplication repair (PRR) pathway, but has additive or synergistic interactions with several other members of this pathway. Although PRR is traditionally divided into an “error-prone” and an “error-free” branch, ANC1 is not epistatic with all members of either established branch, and instead defines a new error-free branch of the PRR pathway. Like several genes involved in PRR, an intact ANC1 gene significantly suppresses spontaneous mutation rates, including the expansion of (CAG)25 repeats. Anc1's role in the PRR pathway, as well as its role in suppressing triplet repeats, point to a possible mechanism for a protein of potential medical interest.
Cyanobacterial ecotypes in the microbial mat community of Mushroom Spring (Yellowstone National Park, Wyoming) as species-like units linking microbial community composition, structure and function

We have investigated microbial mats of alkaline siliceous hot springs in Yellowstone National Park as natural model communities to learn how microbial populations group into species-like fundamental units. Here, we bring together empirical patterns of the distribution of molecular variation in predominant mat cyanobacterial populations, theory-based modelling of how to demarcate phylogenetic clusters that correspond to ecological species and the dynamic patterns of the physical and chemical microenvironments these populations inhabit and towards which they have evolved adaptations. We show that putative ecotypes predicted by the theory-based model correspond well with distribution patterns, suggesting populations with distinct ecologies, as expected of ecological species. Further, we show that increased molecular resolution enhances our ability to detect ecotypes in this way, though yet higher molecular resolution is probably needed to detect all ecotypes in this microbial community.
On the influence of provenance to soil quality enhanced stress reaction of young beech trees to summer drought

Abstract Climate projections propose that drought stress will become challenging for establishing trees. The magnitude of stress is dependent on tree species, provenance, and most likely also highly influenced by soil quality. European Beech (Fagus sylvatica) is of major ecological and economical importance in Central European forests. The species has an especially wide physiological and ecological amplitude enabling growth under various soil conditions within its distribution area in Central Europe. We studied the effects of extreme drought on beech saplings (second year) of four climatically distinct provenances growing on different soils (sandy loam and loamy sand) in a full factorial pot experiment. Foliar δ13C, δ15N, C, and N as well as above‐ and belowground growth parameters served as measures for stress level and plant growth. Low‐quality soil enhanced the effect of drought compared with qualitatively better soil for the above‐ and belowground growth parameters, but foliar δ13C values revealed that plant stress was still remarkable in loamy soil. For beeches of one provenance, negative sandy soil effects were clearly smaller than for the others, whereas for another provenance drought effects in sandy soil were sometimes fatal. Foliar δ15N was correlated with plant size during the experiment. Plasticity of beech provenances in their reaction to drought versus control conditions varied clearly. Although a general trend of declining growth under control or drought conditions in sandy soil was found compared to loamy soil, the magnitude of the effect of soil quality was highly provenance specific. Provenances seemed to show adaptations not only to drought but also to soil quality. Accordingly, scientists should integrate information about climatic pre‐adaptation and soil quality within the home range of populations for species distribution modeling and foresters should evaluate soil quality and climatic parameters when choosing donor populations for reforestation projects.
Real-time classification of malicious URLs on Twitter using machine activity data

Massive online social networks with hundreds of millions of active users are increasingly being used by Cyber criminals to spread malicious software (malware) to exploit vulnerabilities on the machines of users for personal gain. Twitter is particularly susceptible to such activity as, with its 140 character limit, it is common for people to include URLs in their tweets to link to more detailed information, evidence, news reports and so on. URLs are often shortened so the endpoint is not obvious before a person clicks the link. Cyber criminals can exploit this to propagate malicious URLs on Twitter, for which the endpoint is a malicious server that performs unwanted actions on the person's machine. This is known as a drive-by-download. In this paper we develop a machine classification system to distinguish between malicious and benign URLs within seconds of the URL being clicked (i.e. `real-time'). We train the classifier using machine activity logs created while interacting with URLs extracted from Twitter data collected during a large global event - the Superbowl - and test it using data from another large sporting event - the Cricket World Cup. The results show that machine activity logs produce precision performances of up to 0.975 on training data from the first event and 0.747 on a test data from a second event. Furthermore, we examine the properties of the learned model to explain the relationship between machine activity and malicious software behaviour, and build a learning curve for the classifier to illustrate that very small samples of training data can be used with only a small detriment to performance.
Renewal Aging in Non-Homogeneous Poisson Processes with Periodic Rate Modulation

The statistical properties of sequences of Waiting Times generated by Non-Homogeneous Poisson Processes are investigated by means of Renewal Aging, i.e. a statistical analysis being able to detect the presence of genuine renewal events with non-Poisson statistics. The Renewal Aging features of two non-homogeneous Poisson models with different prescriptions of the rate modulation are compared. Both prescriptions are essentially periodic. In the first model, the rate is a totally deterministic and smooth harmonic function. In the second model, the rate modulation is deterministic and smooth almost everywhere, except in some singular points occurring with a periodicity affected by weak random fluctuations. The main parameter of both models is the modulation speed, defined as the ratio between the modulation period and the average Waiting Time. This allows to distinguish between slow, intermediate and fast modulation of the rate. As expected, in the very slow modulation case both models have a strongly reduced Renewal Aging, practically zero, because the analysis is affected by local clusters of Waiting Times with the same Poisson rate. In the intermediate range of modulation speeds, both models show non-zero Renewal Aging and the behavior of the two models tends to be more different as the modulation speed decreases. Going towards the fast modulation regime, the behavior of the two models becomes completely different from one another. Model I does not show a definite global Renewal Aging. On the time scale of the modulation period, local oscillations arise in the Probability Density Function and an apparent oscillating aging is also observed. However, this form of aging is not the manifestation of genuine renewal non-Poisson events, but it is related to the local oscillations. On the contrary, Model II displays Renewal Aging features in agreement with a homogeneous Renewal non-Poisson Process. It is argued that this is related to the singular points in the rate modulation of Model II, which, due to their random occurrence, could be identified with genuine critical non-Poisson events. The approach presented here could have interesting applications in problems involving dichotomous noise and, in particular, in the statistical characterization of ON–OFF fluorescence intermittency experimentally observed in complex systems, such as nano-crystals and single bio-molecules stimulated by laser fields.
Warm-up questions on early childhood memories affect the reported age of earliest memories in late adolescence

Researchers have recently used warm-up questions concerning childhood memories at specific early ages (e.g. 3 years of age) in an attempt to facilitate the retrieval process on the subsequent question regarding the earliest memory. Although this methodology may indeed facilitate the retrieval process by conducting the test in a manner resembling ordinary dialogue, the methodology might also unintentionally put further demand characteristics on the respondents. In the present study we systematically manipulated the target age (either 3 or 6 years of age) for the warm-up question preceding the ‘earliest memory’ question in order to test this possibility. The participants were 445 Danish high school students (M age=17.94). The results revealed that systematically manipulating the target age for the warm-up question had a strong impact on the age of the earliest memory reported by the adolescents. Participants who received warm-up questions with 3 years as the target age subsequently reported earlier first memories than the participants receiving warm-up questions with 6 years as the target age. These results have important implications for the methodology involved in research on childhood amnesia.
Cochain complexes over a functor

In this paper we propose unifying the categories of cochain complexes $\text{Ch}(\mathcal{C})$ and modules $\widehat{A}\text{-mod}$ over a repetitive algebra $\widehat{A}$. Motivated by their striking similarities and importance, we introduce a novel category encompassing both. Our analysis explores key properties of this unified category, highlighting its parallels and divergences from the original structures. We study whether it preserves crucial aspects like limits, colimits, products, coproducts, and abelianity. Besides, we establish a family of projective and injective indecomposable objects within this framework. Moving beyond theoretical foundations, we examine the influence and interaction over these novel categories of the category of endofunctors and its monoidal structure. Finally, we explore the implications of our constructions over representation theory of algebras and algebraic geometry.
Depression after stroke: results of the FINNSTROKE Study.

BACKGROUND AND PURPOSE We compared the incidence and severity of depression at 3 and 12 months after stroke in patients and their chief caregivers (spouses, 63%; children, 37%) in four districts of Finland, two with and two without after-hospital-discharge interventional programs (outpatient rehabilitation and activities of the local divisions of the Finnish Heart Association [FHA]). A population-based stroke register was used, and factors influencing depression were analyzed. METHODS A stroke register of patients recruited over 2 years in four different districts (total population, 134804) in Finland; 594 first-ever strokes were registered. Beck's Depression Inventory (BDI), with 10 as the cutoff point for depression, was applied to 321 of 423 survivors and 195 caregivers at 3 months and to 311 of 390 survivors and 184 caregivers at 12 months in the districts with and without interventional programs. RESULTS At 3 months, fewer patients in the districts with active programs (41%) were depressed than in the control districts (54%) (odds ratio, 0.59; 95% confidence interval, 0.37 to 0.94), and the difference was maintained at 12 months (42% versus 55%) (odds ratio, 0.55; 95% confidence interval, 0.34 to 0.88). Univariate risk factors for depression at 3 months were female sex and severe prognostic score at the onset of stroke (< or = 14 points) on the Scandinavian Stroke Scale (SSS). Only SSS prognostic score and age emerged as significant independent contributors to depression on both linear and logistic multivariate analyses. There was no significant difference in the depression rate of caregivers between districts with active programs (42%) and those without such programs (41%) at 3 months; at 12 months the results were the same (39% in districts with active programs versus 42% in those without such programs). However, at 12 months there were significantly more severely depressed caregivers in districts without active programs than in districts with such programs (P.036). Poor Rankin scale score (grades III through V) and severe SSS long-term score (< or = 42 points) at 3 months among the patients were associated with depression of the caregivers at 3 months in the univariate analysis. Poor Rankin Scale score of the patients was independently associated with the depression of their caregivers at 3 months on multivariate logistic regression analysis. CONCLUSIONS Depression was common among stroke survivors and among their caregivers at 3 months, and its rate did not decrease at 1-year follow-up. The lower depression rate in districts with active programs compared to those without supports the idea that outpatient rehabilitation and support provided by local divisions of the FHA may be an effective way of decreasing the rate of depression after stroke.
Distribution of Nitrate-assimilating Enzymes between Mesophyll Protoplasts and Bundle Sheath Cells in Leaves of Three Groups of C(4) Plants.

Intercellular distribution of enzymes involved in amino nitrogen synthesis was studied in leaves of species representing three C(4) groups, i.e. Sorghum bicolor, Zea mays, Digitaria sanguinalis (NADP malic enzyme type); Panicum miliaceum (NAD malic enzyme type); and Panicum maximum (phosphoenolpyruvate carboxykinase type). Nitrate reductase, nitrite reductase, glutamine synthetase, and glutamate synthase were predominantly localized in mesophyll cells of all the species, except in P. maximum where nitrite reductase had similar activity on a chlorophyll basis, in both mesophyll and bundle sheath cells. NADH-glutamate dehydrogenase was concentrated in the bundle sheath cells, while NADPH-glutamate dehydrogenase was localized in both mesophyll and bundle sheath cells. The activities of nitrate-assimilating enzymes, except for nitrate reductase, were high enough to account for the proposed in vivo rates of nitrate assimilation.Based on the differential centrifugation of cell homogenates of P. miliaceum, mesophyll chloroplasts appear to be the major site of nitrate assimilation since nitrite reductase, glutamine synthetase, glutamate synthase, and NADPH-glutamate dehydrogenase were primarily localized in the chloroplast fraction. Both the glutamine synthetase-glutamate synthase and glutamate dehydrogenase pathways were considered as alternative routes of amino nitrogen synthesis.
Memory and temporal perspective: The role of temporal frameworks in memory development.

Abstract An account of the development of temporal understanding is proposed which links such understanding with the development of episodic memory. We distinguish between different ways of representing time in terms of the kinds of temporal frameworks they involve. Distinctions are made between frameworks that are perspectival or nonperspectival and those that represent recurrent sequences or particular times. Even primitive temporal understanding integrates both perspectival and nonperspectival components. However, since early frameworks are event-based and localized, they are not yet sufficient for episodic memory in that they do not enable the child to think of events as having occurred at particular points in time. We describe the emergence of new kinds of frameworks in terms of the development of temporal decentering. Two levels of temporal decentering are distinguished, with the higher level involving an appreciation of how event representations depend on one's temporal perspective.
Recursive computation of the invariant measure of a stochastic differential equation driven by a Lévy process

We investigate some recursive procedures based on an exact or ``approximate'' Euler scheme with decreasing step in vue to computation of invariant measures of solutions to S.D. E. driven by a Levy process. Our results are valid for a large class of S.D. E. that can be governed by Levy processes with few moments or can have a weakly mean-reverting drift, and permit to find again the a.s. C.L. T for stable processes.
Immunomodulatory and Antidiabetic Effects of a New Herbal Preparation (HemoHIM) on Streptozotocin-Induced Diabetic Mice

HemoHIM (a new herbal preparation of three edible herbs: Angelica gigas Nakai, Cnidium officinale Makino, and Paeonia japonica Miyabe) was developed to protect immune, hematopoietic, and self-renewal tissues against radiation. This study determined whether or not HemoHIM could alter hyperglycemia and the immune response in diabetic mice. Both nondiabetic and diabetic mice were orally administered HemoHIM (100 mg/kg) once a day for 4 weeks. Diabetes was induced by single injection of streptozotocin (STZ, 200 mg/kg, i.p.). In diabetic mice, HemoHIM effectively improved hyperglycemia and glucose tolerance compared to the diabetic control group as well as elevated plasma insulin levels with preservation of insulin staining in pancreatic β-cells. HemoHIM treatment restored thymus weight, white blood cells, lymphocyte numbers, and splenic lymphocyte populations (CD4+ T and CD8+ T), which were reduced in diabetic mice, as well as IFN-γ production in response to Con A stimulation. These results indicate that HemoHIM may have potential as a glucose-lowering and immunomodulatory agent by enhancing the immune function of pancreatic β-cells in STZ-induced diabetic mice.
Snapshot for Time: The One-Shot Case

We show that for one-shot problems - problems where a processor executes a single operation-execution - timing constraints can be captured by conditions on the relation between original outputs and supplementary snapshots. In addition to the dictionary definition of the word snapshot, in distributed computing snapshots also stand for a task that imposes relation among sets which are output of processors. Hence, constrains relating the timing between operation-executions of processors can be captured by the sets relation representing a task. This allows to bring to bear techniques developed for tasks, to one-shot objects. In particular, for the one-shot case the question of linearizability is moot. Nevertheless, current proof techniques of object implementation require the prover to provide linearization-points even in the one shot case. Transforming the object into a task relieves the prover of an implementation from the burden of finding the "linearization-points," since if the task is solvable, linearization points are guaranteed to exist. We exhibit this advantage with a new algorithm to implement MWMR register in a SWMR system.
Hematopoietic effect of melatonin involvement of type 1 K‐opioid receptor on bone marrow macrophages and interleukin‐1

Abstract: Melatonin has immuno‐enhancing properties and exerts colony‐stimulating activity (CSA) via T‐helper cell‐derived opioids. Opioid agonists may mimic the CSA of melatonin with an order of potency that suggests the presence of a type 1 K‐opioid receptor (type I kOR [KI‐OR]). The kOR antagonist nor‐binaltorphimine neutralized the in vitro effect of melatonin and inhibited regeneration of hematopoiesis in mice treated with carboplatin. The CSA of dynorphin A was abolished by incubation of adherent cells with antisense (AS) oligodeoxynucleotide to kOR or by addition of anti‐interleukin (IL)‐I monoclonal antibody (mAb), which also neutralized the effect of melatonin. Bone marrow cells that express kORs were identified to be macrophages. In conclusion, we describe the presence of kORs in bone marrow macrophages and suggest a hematopoietic function for melatonin via endogenous K‐opioid agonists and, possibly, IL‐I.
