Enabling educators to teach and understand intercultural communication: the example of “Young people on the global stage: their education and influence”

ABSTRACT “Young people on the global stage: their education and influence” is an EU-funded project that involves teachers and students from three European countries (Britain, Germany and Spain) and teachers from several African countries with a focus on The Gambia and Kenya. The main aim of the project is to promote an understanding of some of the Millennium Development Goals, namely poverty and hunger (MDG 1), environmental sustainability (MDG 7) and the encouragement of a global partnership for development (MDG 8). In relation to the teachers the project organises national CPDs (continuing professional developments) as well as collaborative study visits to the main African partner countries. When conceptualizing these study trips, it was assumed that teachers in a nationally mixed group may help each other to see things from a different perspective. Whether this can be empirically proven is the focus of a research project that is conducted alongside the project. This paper takes a step back and analyses the intercultural communication in the European group before the first study trip took place. It thus not only provides an understanding of the workings of European collaborations, but also some of the necessary background to understand the experiences of the study visit courses.
A single amino acid mutation of OsSBEIIb contributes to resistant starch accumulation in rice

Foods rich in resistant starch can help prevent various diseases, including diabetes, colon cancers, diarrhea, and chronic renal and hepatic diseases. Variations in starch biosynthesis enzymes could contribute to the high content of resistant starch in some cultivars of rice (Oryza sativa L.). Our previously published work indicated that the sbe3-rs gene in the rice mutant line, ‘Jiangtangdao1’ was a putative allele of the rice starch branching enzyme gene SBEIIb (previously known as SBE3); sbe3-rs might control the biosynthesis of the high resistant starch content in the rice line. Biomolecular analysis showed that the activity of SBEs was significantly lower in soluble extracts of immature seeds harvested from ‘Jiangtangdao1’ 15 days after flowering than in the extracts of the wild-type rice line ‘Huaqingdao’. We performed gene complementation assays by introducing the wild-type OsSBEIIb into the sbe3-rs mutant ‘Jiangtangdao1’. The genetically complemented lines demonstrated restored seed-related traits. The structures of endosperm amylopectin and the morphological and physicochemical properties of the starch granules in the transformants recovered to wild-type levels. This study provides evidence that sbe3-rs is a novel allele of OsSBEIIb, responsible for biosynthesis of high resistant starch in ‘Jiangtangdao1’.
Weyl Groups, the Hard Lefschetz Theorem, and the Sperner Property

Techniques from algebraic geometry, in particular the hard Lefschetz theorem, are used to show that certain finite partially ordered sets $Q^X $ derived from a class of algebraic varieties X have the k-Sperner property for all k. This in effect means that there is a simple description of the cardinality of the largest subset of $Q^X $ containing no $( k + 1 )$-element chain. We analyze, in some detail, the case when $X = G/P$, where G is a complex semisimple algebraic group and P is a parabolic subgroup. In this case, $Q^X $ is defined in terms of the “Bruhat order” of the Weyl group of G. In particular, taking P to be a certain maximal parabolic subgroup of $G = SO( 2n + 1 )$, we deduce the following conjecture of Erdos and Moser: Let S be a set of $2\ell + 1$ distinct real numbers, and let $T_1 , \cdots ,T_k $ be subsets of S whose element sums are all equal. Then k does not exceed the middle coefficient of the polynomial $2( 1 + q )^2 ( 1 + q^2 )^2 \cdots ( 1 + q^\ell )^2 $, and this bound is best poss.
Sorafenib Decreases Tumor Exposure to an Anti-carcinoembryonic Antigen Monoclonal Antibody in a Mouse Model of Colorectal Cancer

In this investigation, we test the hypothesis that treatment with sorafenib, an anti-angiogenic agent, decreases tumor vascularization and, consequently, hinders the delivery of monoclonal antibodies (mAb) to xenograft tumors. Severe combined immunodeficiency mice bearing carcinoembryonic antigen (CEA) expressing tumor xenografts were divided into control and sorafenib-treated groups. Sorafenib was administered to the latter group at 50 mg/kg IP every 48 h, starting 4 days post-tumor implantation. When tumors attained a size of 200–300 mm3, mice were evaluated for (a) tumor microvessel density (using immunohistochemical analysis), (b) tumor macromolecular extravasation (using Evans Blue Dye (EBD)), (c) pharmacokinetics of an anti-CEA mAb, T84.66, following an intravenous dose of 10 mg/kg, and (d) intra-tumoral spatial distribution of T84.66 (using autoradiography). Sorafenib treatment resulted in a substantial reduction in tumor growth rate, a visible reduction in tumor microvessel density, and in a 46.4% decrease in EBD extravasation in tumor tissue (p < 0.0455). For control and treated mice, no significant difference was found for the area under the mAb plasma concentration-time curve (AUC(0–7d): 1.67 × 103 ± 1.28 × 102vs. 1.76 × 103 ± 1.75 × 102 nM × day, p = 0.51). However, tumor AUC(0–7d) was reduced by 40.8% in sorafenib-treated mice relative to that observed in control mice (5.61 × 102 ± 4.27 × 101vs. 9.48 × 102 ± 5.61 × 101 nM × day, p < 0.001). Sorafenib therapy was also found to markedly alter mAb tumor spatial distribution. The results collectively suggest that sorafenib treatment causes a significant reduction in mAb delivery to, and distribution within, solid tumors.
Novel Organization of Genes Involved in Prophage Excision Identified in the Temperate Lactococcal Bacteriophage TP901-1

ABSTRACT In this work, the phage-encoded proteins involved in site-specific excision of the prophage genome of the temperate lactococcal bacteriophage TP901-1 were identified. The phage integrase is required for the process, and a low but significant frequency of excision is observed when the integrase is the only phage protein present. However, 100% excision is observed when the phage protein Orf7 is provided as well as the integrase. Thus, Orf7 is the TP901-1 excisionase, and it is the first excisionase identified that is used during excisive recombination catalyzed by an integrase belonging to the family of extended resolvases. Orf7 is a basic protein of 64 amino acids, and the corresponding gene (orf7) is the third gene in the early lytic operon. This location of an excisionase gene of a temperate bacteriophage has never been described before. The experiments are based on in vivo excision of specifically designed excision vectors carrying the TP901-1 attP site which are integrated intoattB on the chromosome of Lactococcus lactis. Excision of the vectors was investigated in the presence of different TP901-1 genes. In order to detect very low frequencies of excision, a method for positive selection of loss of genetic material based upon the upp gene (encoding uracil phosphoribosyltransferase) was designed, since upp mutants are resistant to fluorouracil. By using this system, frequencies of excision on the order of 10−5 per cell could easily be measured. The described selection principle may be of general use for many organisms and also for types of deletion events other than excision.
A Case Study of Land-Surface-Temperature Impact from Large-Scale Deployment of Wind Farms in China from Guazhou

The wind industry in China has experienced a rapid expansion of capacity after 2009, especially in northwestern China, where the China’s first 10 GW-level wind power project is located. Based on the analysis from Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) data for period of 2005–2012, the potential LST impacts from the large-scale wind farms in northwestern China’s Guazhou are investigated in this paper. It shows the noticeable nighttime warming trends on LST over the wind farm areas relative to the nearby non-wind-farm regions in Guazhou and that the nighttime LST warming is strongest in summer (0.51 °C/8 years), followed by autumn (0.48 °C/8 years) and weakest in winter (0.38 °C/8 years) with no warming trend observed in spring. Meanwhile, the quantitative comparison results firstly indicate that the nighttime LST warming from wind farm areas are less than those from the urban areas in this work.
Phase Anomalies and Plateaus in Auditory Nerve Fiber Responses to High-Frequency Tones

Phase reversals and phase plateaus have been found in studies that measure motion of the basilar membrane (BM) at the base of the cochlea in response to high-level sounds above the characteristic frequency (CF). In contrast, such patterns have not been found in responses of auditory-nerve fibers (ANF) from the base of the cochlea, primarily because these ANFs do not have synchronized responses to high-frequency tones. We sought counterparts to the BM responses in auditory nerve fibers (ANF) by using a new method that extracts phase information from beat-producing multi-tone stimuli. The method can determine the relative phases of ANF responses to high-frequency tones by measuring the phases of low-frequency beats and from these beats, reconstructing the relative phases of the original tone response. We also used amplitude modulated (AM) tones at high sound levels. The data collected suggest that the new beat-producing phase-analysis method is effective at tip and tail regions of the ANF tuning curves. However, this method has low success in measurements at frequencies above CF due to low signal-to-noise ratios and large distortion products in the ANF responses. AM tones, however, were more successful and showed significant evidence of a phase plateau at high levels and at frequencies well above the fiber's CF. Thus this plateau response appears to be present in ANF firings as well as BM motion. ANF responses to multi-tone stimuli presented above CF and at moderate level resulted in an anomalous negative group delay. Presuming that the multitone method yields a valid picture of the original high frequency phase responses we speculate that the anomaly is produced by complex interactions among two or more response components at the above-CF region of the ANF tuning curve.

On the Foundations of Beliefs in Free Will

The concept of an ability to make choices and to determine one’s own outcomes fits well with experiences that most people have, and these experiences form the basis for beliefs in free will. However, the existence of conscious free will is challenged by modern research findings highlighting the unconscious origins of goal-directed behavior that gives rise to free-will beliefs. This report expands on these insights by revealing that both conscious and unconscious processes play an important role in free-will beliefs. Specifically, Experiment 1 demonstrates that free-will beliefs are strengthened when conscious intentions to produce action outcomes bind the perception of action and outcome together in time. Experiment 2 shows that these beliefs are strengthened when unconscious priming of action outcomes creates illusory experiences of self-agency when the primed outcomes occur. Together, these findings suggest that beliefs in free will are associated with self-agency and are enhanced by both conscious and unconscious information processing of goal-directed behavior.
Batteries Not Included: A Mat-Based Wireless Power Transfer System for Implantable Medical Devices As a Moving Target

Implantable devices have become increasingly popular in modern medicine. These devices have a wide range of applications, such as health monitoring, disease prevention, delivery of a therapeutic regimen, and biomimetic prosthesis. For example, electrical stimulation of nerve tissue and recording of neural electrical activity are the basis of emerging prostheses and treatments for spinal cord injury, stroke, sensory deficits, and neurological disorders [1]-[5]. Being able to record neural activity from awake animals with observable behavior has greatly advanced our understanding of the neural mechanisms that mediate behavior. Conventional microelectrode recording techniques typically require a percutaneous connector, which is associated with infection risks. Generally, in order to obtain stable recordings, animals must be trained to accept some degree of restraint (e.g., head fixation). Not only is the mobility of the animal subject limited, but the results obtained under such restricted conditions may not reflect the full repertoire of brain activity that occurs during natural behaviors [2]. This issue can be addressed with implantable electronics to record neural activity and wirelessly transmit this data through the skin to an external device. A wireless technique is then required to transmit both data and power, connecting the external system and the implanted devices.
An Overview of the Beneficial Effects of Hydrolysed Collagen as a Nutraceutical on Skin Properties: Scientific Background and Clinical Studies

Skin, the main barrier to the external environment, is subject to deterioration caused by dermatological disorders, environmental conditions and the intrinsic ageing process. This damage to both structure and function may be accelerated by smoking, alcohol consumption and chronic sun exposure (extrinsic components). All these factors may lead to the formation of wrinkles, the appearance of brown spots and skin thickening. One effective strategy to managing the skin ageing process is adopting a healthy nutritional approach to life, maintaining a balanced diet and a good supply of food supplements. This can restore the homeostasis of macro and micronutrients and support the physiology of cells and tissues in the skin. Hydrolysed collagen, an increasingly popular nutraceutical, is composed of low molecular weight small peptides, which are easily digestible, absorbed and distributed in the human body. Numerous clinical trials have now been performed showing the efficacy and benefits of collagen peptides on skin properties, such as hydration, elasticity and reduction of wrinkles. As a result, hydrolysed collagen can be considered an important weapon in the everyday fight against skin ageing.
On Measurements of the Factor Content of Trade: - The Case of Sweden

In this paper we evaluate different measurement practices when calculating the human capital content of a country's net trade. The calculations are performed using a structural measure developed by Lundberg & Wiker (1997) that relates the average factor input requirements in exports relative to those in imports. We find the calculations highly dependent on measurement practice when performing those on a cross-section for a single year. However, when calculating the human capital content of trade over time instead, the inclusion of service sectors in the trade vector as well as variable factor input requirements seem to be very important. This paper then continues with an empirical evaluation of the human capital content of Swedish trade in 1986-2000. We find that during the period 1986-1992, the average human capital intensity in exports relative to imports was slightly increasing, mirroring an increased specialization in human capital-intensive production. After 1992, though, there is a rapid decrease in the human capital content of trade in exports relative to imports. In 1995 there is a recovery, but the recovery seems both to be leveling out and turning down in the late 1990's. In this paper we also draw the conclusion that a well functioning educational system is important for a country's comparative advantage.
Relax, but Do Not Sleep: A new perspective on Green Wireless Networking

Saving power on base stations (BS) becomes a critical issue in wireless cellular networks. Many existing work has proposed to schedule BS into sleep to save energy. However, in reality, it is very difficult to shut down and reboot BSs frequently due to numerous technical issues and performance requirements. In this work, we propose a much more practical solution and offer a new perspective on implementing Green Wireless Networking by embracing the hot-trended small cell network idea. Instead of putting BSs into sleep, we tactically reduce the coverage (and the power usage) of each BS, and strategically place microcells (relay stations) to offload the traffic transmitted to/from BSs in order to save total power consumption. We propose approximation algorithms for various network design scenarios, with different wireless network setups and different power saving optimization objectives. Extensive numerical results are presented to confirm our theoretical analysis.
Transformational leadership behavior, emotions, and outcomes: Health psychology perspective in the workplace

ABSTRACT The purpose of this study is to empirically evaluate the transformational leadership styles, emotions, and organizational outcomes among different professionals in different sectors. The transformational leadership and emotions theories were utilized and tested in a sample of 128 leaders in Sweden. The main objectives of the study are (1) to determine which of the transformational leadership styles (TLS) are best at predicting effective outcomes (OUT) of extra effort by employees (EXE), leader effectiveness (EFE) and job satisfaction (SAT) and (2) to examine which TLS predict significant positive emotions (TEMO). Results of the study reveal that TLS and most of the outcome scales (SAT, EXE, SAT) are positively and significantly correlated. Charisma (C) and idealized influence (II) are not correlated with EFE. The results further supported that inspirational motivation leaders behavior could produce greater amounts of SAT (r = .54**), EXE (r = .41**). Individualized consideration (IC) also generates great SAT, r = . 42. The study also found that only inspirational motivation (I) and intellectual stimulator leadership styles made a significance for TEMO such as being enthusiastic, hopeful, proud, happy, attentive, and inspiring with β = 26 and β = 17, respectively. Inspirational transformational leaders’ behavior and emotions are the most capable in increasing the organizational overall outcomes by boosting employees’ job satisfaction, additional effort, and effectiveness. Hence, these improve and enhance the mental and psychological health inside and outside the workplace.

Conventional Wisdom is Often Misleading: Police Stress Within an Organisational Health Framework

The attached book chapter is one of the most comprehensive scientific articles on the nature and determinants of police stress. Using a large sample of serving Australian police officers, the authors examined how the levels of occupational well-being among police officers compared with other occupational groups, and then examined whether police officers’ levels of occupational wellbeing were determined by their personality characteristics, their use of coping strategies, the climate of their organisation, or their operational and organisational work experiences. Results showed that:
Adaptive control of functional electrical stimulation for upper limb stroke rehabilitation

In this paper a multiple model adaptive control scheme is designed and evaluated for the electrically stimulated isometric human arm. Experimental data are first used to identify models that represent various stages of muscular fatigue. The control scheme is then implemented on four unimpaired participants supplying zero voluntary effort. Results illustrate the ability of the scheme to track the time-variance of the true plant and provide improved torque tracking compared with a fixed controller. An advantage of the proposed method is the ability to achieve similar levels of performance across multiple participants without the need to perform identification tests.
THE ULTRASTRUCTURE OF ASCOSPORE DELIMITATION IN SACCOBOLUS KERVERNI

The mechanics of spore del imitat ion within the ascus have long been a topic of controversy among ascomycete cytologists. Lateral fusion of recurving astral rays a round each nucleus following the mitotic, th i rd division in the ascus (6), progressive differentiation of spore membranes in a granular layer of cytoplasm around each nucleus (5), fusion of epiplasmic vacuoles (8), and invaginat ion of a per ipheral membrane system in the ascus (3) all have been cited in at tempts to describe this process under the l ight microscope. Carroll (2) and Reeves (12) provide more complete discussion of the process. Early observations of the ul trastructure of developing ascospores revealed only tha t following meiosis each nucleus somehow is surrounded by at least one membrane , outside of which the spore wall develops (7). Later studies have demonstrated tha t each spore is delimited by two membranes, an inner plasma membrane and an outer investing membrane , between which the spore wall is deposited (1, 4, 9-11, 12, 13). Recently, Reeves (12) has shown tha t in Pyronema domestica the spore membranes originate in an open-ended per ipheral cylinder of double m e m b r a n e which initially surrounds all eight nuclei in the ascus. As the m e m b r a n e cylinder constricts between the seriate nuclei, it pinches out a row of ascospores. T h e present study was carr ied out to investigate the origin of the spore membranes in the discomycete, Saccobolus.
