Building career capital: developing business leaders' career mobility

Career theorists have been increasingly occupied with role transitions across organisations, neglecting role transitions undertaken within single organisations. By exploring in depth the aspects of career capital that role holders need to facilitate their own organisational role transition, this article builds upon career capital theory. ,Adopting an interpretivist approach, this study explores the experiences of 36 business leaders who have undertaken a recent role transition within a UK construction business. ,The article empirically characterises 24 career capital aspects, clustered into Knowing Self, Knowing How and Knowing Whom. It argues that these aspects are important to internal role transitions and compares them to mainstream career capital theory. In addition, the concepts of connecting, crossing and investing career capital are introduced to explain how career capital supports such transitions. ,This study proposes a new career capital framework and refocuses debate on organisational careers. It is based on a single organisation, and it would be beneficial for future researchers to explore its applicability within other organisations. ,The article explores the implications of the new career capital framework for business leaders and organisational managers who wish to build individual and organisational career mobility. ,This study proposes a new, empirically grounded, career capital theoretical framework particularly attending to organisational role transitions.

An overview of the main solid-state technologies is provided, including Si, gallium arsenide (GaAs), GaN, and other III–V materials, and both field-effect and bipolar transistors. The most popular broadband design techniques are introduced, before critically comparing through the most relevant design examples found in the scientific literature. Given the wide breadth of applications that are foreseen to exploit the mm-wave spectrum, this contribution will represent a valuable guide for designers who need a single reference before adventuring in the challenging task of the mm-wave PA design.
Functional morphology of sexually selected gentalia in the water strider Aquarius remigis

In the water strider Aquarius remigis (Say), sexual selection favours males with longer genitalia. We used video analysis plus light and scanning electron microscopy to examine the structure, movement, and articulation of the genitalia as a first step in determining the functional basis of this selection. Male A. remigis are characterized by long, robust genital segments; a marked ventral median notch in the posterior margin of the pregenital segment; an enlarged phallus tipped with a uniquely prolonged sclerotized plate; and a large, spine-covered, membranous lobe that inflates within the female's reproductive tract. Detailed examinations of genital interactions prior to and during copulation allow us to deduce the functional significance of these distinguishing traits. We postulate that by increasing the length, mobility, strength, and rigidity of the phallus, the first three traits increase the ability of males to achieve intromission in spite of active female resistance, and to maintain intromission d.
Legume Production and Irrigation Strategies in the Aral Sea Basin: Yield, Yield Components, Water Relations and Crop Development of Common Bean (Phaseolus vulgaris L.) and Mungbean (Vigna radiata (L.) Wilczek)

With world population expected to reach 9.2 billion people by 2050, improved irrigation methods will be needed to increase the productivity of agricultural land and improve food supply worldwide. The objective of this work was to examine the effect of regulated deficit irrigation (RDI) and alternate furrow irrigation (AFI) on the yield and yield components of two legume species (common bean and mungbean) produced as a second crop following winter wheat in Uzbekistan, Central Asia. Water relations and crop development were also examined. The research was conducted during two successive growing seasons in the Fergana valley. Production of mungbean using the severe stress RDI treatment in combination with AFI resulted in the highest yields with the lowest quantity of applied water in 2004. In addition, yields of common bean in the moderate stress treatment were not different from the recommended schedule, although irrigation events were decreased from 4 to 2. AFI did not reduce yields, and it did not interact with RDI to reduce yields further. In general, mungbean yields were higher than those of common bean. The combination of AFI and RDI can allow legume production with reduced water inputs.
Rural people's intention to adopt sustainable water management by rainwater harvesting practices: application of TPB and HBM models

Water is the prerequisite for human adaptation to climate change and is the key link among climatic conditions, humans, and the environment. Human behavior can mitigate the impacts of climate change. The present study aimed to evaluate rural people's readiness for sustainable management of water resources. To achieve this goal, the Theory of Planned Behavior (TPB) and Health Belief Model (HBM) were used as the research framework. The research instrument was a closed-end questionnaire developed on the basis of TPB and HBM. The face and content validity of the questionnaire was confirmed by a panel of experts in sustainable agriculture. Its reliability was also checked in a pilot study by calculating Cronbach's alpha, the average variance extracted (AVE), R2, and composite reliability (CR). The research sample was composed of 480 villagers from Hamadan province, Iran, who were familiar with sustainable water resources management in the context of the rooftop rainwater harvesting project. The results showed that in TPB, the variables of moral norms, attitude, and self-identity could account for 61 percent of the variance in rural people's intention to adopt the practices of sustainable water resources management. Based on HBM, the variables of perceived benefits, perceived susceptibility, and perceived severity could capture 49 percent of this variance. The results revealed that both theories had the potential to predict rural people's intention to engage in the sustainable management of water resources, but TPB proved to provide a more robust prediction than HBM.
Yield loss quantification and assessment of economic injury level for the anthophagous generation of the European grapevine moth Lobesia botrana Den. et Schiff. (Lepidoptera: Tortricidae)

Until now, no attempts have been made to assess systematically the damage to vine from the first (anthophagous) generation of the European grapevine moth Lobesia botrana Den. et Schiff. (Lepidoptera: Tortricidae). No standards for intervention have been established; consequently, control measures are undertaken arbitrarily and regardless of economic costs. In the region of East Attiki in Greece, where the wine variety ‘Savvatiano’ is grown, the larvae of the first generation of the moth may destroy not only blossoms, but also newly set berries. Damage simulation experiments, carried out in this area to study the variety's response to injury of blossoms and berries, showed that it has the capacity to compensate completely for the damage to the blossoms by means of a proportionate decrease in shedding of natural blossoms. However, it cannot make up for damage to young berries. The yield loss from the first generation larvae was calculated over the years 1995 – 1999 and economic injury levels (EILs) were assessed The loss of yield, in this case exclusively from injury to berries, was found to be, on average, 15.5 g/grape, 75.5 kg/ha or 3.6%. The EIL, measured in units of injury and numbers of pest specimens using simple empirical equations incorporating dynamic biological and economic factors, fluctuated only slightly during the 5 years of the survey, averaging 7.7 larval ‘nests’/inflorescence or 3.6 larvae/inflorescence. Although the EIL is specific to the Savvatiano variety and the East Attiki region, the methodology employed could have a broader application.
Breeding phenology in relation to NDVI variability in free‐ranging African elephant

The phenology of reproduction is often correlated with resource availability and is hypothesized to be shaped by selective forces in order to maximize lifetime reproductive success. African elephants have the distinctive life history traits of a 22 month gestation and extended offspring investment, necessitating a long-term strategy of energy acquisition and reproductive expenditure to ensure successful offspring recruitment. We investigated the relationship between the reproductive phenology of a wild elephant population and resource availability using remotely sensed Normalized differential vegetation index (NDVI) data as a measure of time-specific primary productivity and hence forage quality. The initiation of female elephants’ 3 /yr reproductive bout was dependent on conditions during the season of conception but timed so parturition occurred during the most likely periods of high primary productivity 22 months later. Thus, the probability of conception is linked to the stochastic variation in seasonal quality and the phenology of parturition is related to the predictable seasonality of primary productivity, indicating elephants integrate information on known current and expected future conditions when reproducing. Juvenile mortality was not correlated with ecological variability, hence female fecundity rather than calf mortality appears to drive demographic processes in the study population.
Distribuição de atividades econômicas e centralidades em redes espaciais urbanas: estudo de caso: Lorena (Brasil) | Distribution of economic activities and centralities in urban spatial networks: study case:Lorena (Brazil)

Ultimamente, a aplicacao de redes espaciais urbanas vem ganhando destaque em trabalhos que envolvem Sistemas de Informacao Geografica. Assim, modelos de centralidade tem sido aplicados a fim de diferenciar espacos e descrever aspectos vinculados a estrutura espacial urbana. Neste trabalho, e explorada a relacao entre o fenomeno da distribuicao de atividades economicas e as propriedades do espaco urbano, utilizando-se a teoria de redes como base metodologica. Considerando-se tres propriedades espaciais — Acessibilidade, Intermediacao e Excentricidade —, foram aplicados modelos de centralidade capazes de diferenciar porcoes discretas de espaco urbano sobre a rede espacial formada por trechos de ruas da cidade de Lorena (Sao Paulo). Na sequencia, os resultados da aplicacao desses modelos foram comparados, estatisticamente, com suas respectivas quantidades de atividades economicas. O coeficiente de correlacao Pearson (r) foi utilizado para verificar qual desses modelos se associaria ao fenomeno da distribuicao de atividades economicas urbanas de forma mais adequada. Os resultados sugerem uma correlacao moderada entre os valores de centralidade por excentricidade e centralidade por proximidade, processadas de forma geometrica, com a distribuicao espacial de atividades economicas na cidade de Lorena (Sao Paulo).
P142: Perspectives of medical students and undergraduate students on their experience as medical scribes in the Saint John Regional Hospital Emergency Department

Introduction: Electronic medical records (EMR) have placed increasing demand on emergency physicians and may contribute to physician burnout and stress. The use of scribes to reduce workload and increase productivity in emergency departments (ED) has been reported. This objective of this study was to evaluate the educational and experiential value of scribing among medical and undergraduate students. We asked: “Will undergraduates be willing to scribe in exchange for clinical exposure and experience? ”; and, “Should scribing be integrated into the medical school curriculum? ” Methods: A mixed-methods model was employed. The study population included 5 undergraduate, and 5 medical students. Scribes received technical training on how to take physician notes. Undergraduate students were provided with optional resources to familiarize themselves with common medical terminology. Scribes were assigned to physicians based on availability. An exit interview and semi-structured interviews were conducted at the conclusion of the study. Interviews were transcribed and coded into thematic coding trees. A constructivist grounded theory approach was used to analyze the results. Themes were reviewed and verified by two members of the research team. Results: Undergraduate students preferred volunteering in the ED over other volunteer experiences (5/5); citing direct access to the medical field (5/5), demystification of the medical profession (4/5), resume building (5/5), and perceived value added to the health care team (5/5) as main motivators to continue scribing. Medical students felt scribing should be integrated into their curriculum (4/5) because it complemented their shadowing experience by providing unique value that shadowing did not. Based on survey results, five undergraduate students would be required to cover 40 volunteer hours per week. Conclusion: A student volunteer model of scribing is worthwhile to students and may be feasible; however, scribe availability, potentially high scribe turnover, and limited time to develop a rapport with their physician may impact any efficiency benefit scribes might provide. Importantly, scribing may be an invaluable experience for directing career goals and ensuring that students intrinsically interested in medicine pursue the profession. Medical students suggested that scribing could be added to the year one curriculum to help them develop a framework for how to take histories and manage patients.
Auxiliary network sampling for multi-objective national forest inventories: a practical examination of search distances

Building upon the work of Roesch and McWilliams (2007), this paper discusses additional examples of an auxiliary sampling strategy that allows National Forest Inventory (NFI) practitioners to efficiently estimate the attributes of rare events or species. When the rare event is immediately identifiable in the field, such as the tree species itself, a trivial simplification of theory is evident, that being that clusters of networks of trees (of that species) are being sampled by the area-based plot, rather than clusters of individual trees. When this is the case one does not have to think of the design as adaptive but rather as simply auxiliary. This can be of some help in the presentation of a large, multi-objective inventory. This paper focuses on a practical examination of network search distances for this special case of an auxiliary mechanism for NFIs such as the Forest Inventory and Analysis (FIA) sample design in the United States.
Rapid Quantification and Neutralization Assays for Novel Coronavirus SARS-CoV-2 Using Avicel RC-591 Semi-Solid Overlay

When working with the novel coronavirus SARS-CoV-2 during a pandemic response, having a rapid, reproducible and reliable assay for infectious virus quantitation and utilization for evaluation of potential therapeutics is critical. Compared to traditional agarose overlay plaques visualized with neutral red, assays performed with Avicel R RC-591 semi-solid overlay provide a simplified format for rapid and easy detection and neutralization testing. The method is easily modified for higher throughput using dispensers or automated processing. Fixation using formalin provides flexibility when dealing with pathogenic agents such as SARS-CoV-2 where tissue culture plates might be removed from biocontainment for staining. Although plaque assays are considered straightforward in principle, having an easily reproducible, consistent plaque assay is an invaluable tool.
A Low-Power High-Speed Sense-Amplifier-Based Flip-Flop in 55 nm MTCMOS

In this paper, a sense-amplifier-based flip-flop (SAFF) suitable for low-power high-speed operation is proposed. With the employment of a new sense-amplifier stage as well as a new single-ended latch stage, the power and delay of the flip-flop is greatly reduced. A conditional cut-off strategy is applied to the latch to achieve glitch-free and contention-free operation. Furthermore, the proposed SAFF can provide low voltage operation by adopting MTCMOS optimization. Post-layout simulation results based on a SMIC 55 nm MTCMOS show that the proposed SAFF achieves a 41.3% reduction in the CK-to-Q delay and a 36.99% reduction in power (25% input data toggle rate) compared with the conventional SAFF. Additionally, the delay and the power are smaller than those of the master-slave flip-flop (MSFF). The power-delay-product of the proposed SAFF shows 2.7× and 3.55× improvements compared with the conventional SAFF and MSFF, respectively. The area of the proposed flip-flop is 8.12 μm2 (5.8 μm × 1.4 μm), similar to that of the conventional SAFF. With the employment of MTCMOS optimization, the proposed SAFF could provide robust operation even at supply voltages as low as 0.4 V.
Strong Interrelation between the Short-Term Variability in the Ionosphere, Upper Mesosphere, and Winter Polar Stratosphere

We perform a joint analysis of short-period (up to several hours) variability in parameters of the ionosphere, the mesosphere, and the stratosphere at mid-latitude, subauroral, and high-latitude points for a long time interval. The study is based on the ionospheric total electron content (TEC) measurements and data on the OH rotational temperature at the mesopause height. We reveal similar seasonal variations in the dynamics of the short-term variability level, both in the ionosphere and the mesosphere. Maximum variability is observed during winter months and it exceeds the values in summer period up to 5–6 times. The revealed dynamics has no explicit relation to the levels of geomagnetic and solar activities. We suggest that the instabilities in the high-velocity stratospheric subauroral winter jet stream may be a source of the recorded variability seasonal variations in the ionosphere and the mesosphere. We propose a new index to estimate a short-term variability in the stratosphere. The index is shown to experience similar regular seasonal variations with a maximum during winter months. We show a clear correlation between the mesosphere/ionosphere variability indices values and the stratosphere disturbance index. The correlation is shown to be higher for the mesosphere variability index as compared with that in the ionosphere, and at the high-latitude point located closer to the jet stream. The obtained results indicate a strong interrelation between the short-period variability in the ionosphere, in the upper mesosphere, and in the subauroral stratosphere. The results contribute to elucidating the basic mechanisms for a vertical coupling between different atmospheric layers.
Efficient Repair Analysis Algorithm Exploration for Memory With Redundancy and In-Memory ECC

In-memory error correction code (ECC) is a promising technique to improve the yield and reliability of high density memory design. However, the use of in-memory ECC poses a new problem to memory repair analysis algorithm, which has not been explored before. This article first makes a quantitative evaluation and demonstrates that the straightforward algorithms for memory with redundancy and in-memory ECC have serious deficiency on either repair rate or repair analysis speed. Accordingly, an optimal repair analysis algorithm that leverages preprocessing/filter algorithms, hybrid search tree, and depth-first search strategy is proposed to achieve low computational complexity and optimal repair rate in the meantime. In addition, a heuristic repair analysis algorithm that uses a greedy strategy is proposed to efficiently find repair solutions. Experimental results demonstrate that the proposed optimal repair analysis algorithm can achieve optimal repair rate and increase the repair analysis speed by up to <inline-formula><tex-math notation="LaTeX">$10^5\times$</tex-math><alternatives><mml:math><mml:mrow><mml:msup><mml:mn>10</mml:mn><mml:mn>5</mml:mn></mml:msup><mml:mo>×</mml:mo></mml:mrow></mml:math><inline-graphic xlink:href="sun-ieq1-2996747.gif"/></alternatives></inline-formula> compared with the straightforward exhaustive search algorithm. The proposed heuristic repair analysis algorithm is approximately 28 percent faster than the proposed optimal algorithm, at the expense of 5.8 percent repair rate loss.

The user and sum capacities of the proposed NOMA-OAM-MIMO scheme is analyzed and compared with other conventional schemes such as conventional NOMA with MIMO, and conventional orthogonal multiple access with OAM-MIMO multiplexing.
Adaptive Color Selection to Limit Power Consumption for Multi-Object GUI Applications in OLED-Based Mobile Devices

Recently, as OLED displays are widely used in smartphones, their power management has become an important issue. Since OLED display devices show a large difference in power consumption depending on the colors used, proper color selection is important to reduce power consumption, but this may affect quality-of-experience (QoE) perceived by users. To address this tradeoff, this paper proposes a new power management scheme for graphical-user-interface (GUI) applications in OLED-based mobile devices. First, we examine the relationship between power consumption and color usage based on actual measurements and derive a model to express color preferences. Next, we present a dynamic programming algorithm that adaptively changes the color of the GUI objects in the applications to limit the total power consumption while effectively reflecting the color preferences of the user. The proposed scheme was implemented on a commercial smartphone, and real power measurements were conducted to examine whether it uses the given energy budget accurately under various color preference configurations. Experimental results show that color preferences significantly affect both power consumption and QoE, thereby demonstrating that personalized color selection plays an important role in reducing total power consumption of an OLED smartphone.
