Examining Differentiation of Self Within Career Construction Model of Adaptation

The present study examined the role of differentiation of self (DoS) in the career construction model of adaptation (CCMA) using a total sample of 243 married adults. Specifically, career construction theory (CCT) was extended by integrating Bowen family systems theory (BFST) and incorporating DoS as an adaptivity construct into the model. The data displayed a good fit to the model, and all hypothesized associations were supported. The direct paths from DoS to career adaptability, job, life, and marital satisfaction were positive and significant, as were the paths from career adaptability to job, life, and marital satisfaction. Furthermore, the mediation effect of career adaptability between DoS and job, life, and marital satisfaction was also significant. Based on these results, the implications and future research directions were discussed.
Performance evaluation of seismically isolated buildings near active faults

This paper investigates the collapse risk of seismically isolated buildings that are designed by the procedures of the ASCE/SEI 7‐16 standard for sites within 5 km of the active fault that controls the hazard. The study is based on six‐story perimeter frame buildings designed with special concentrically braced frames for a location in California. The seismic isolation systems considered in this study are comprised of either: (i) triple friction pendulum bearings with high friction coefficients at the sliding interfaces, (ii) triple friction pendulum bearings with low friction coefficient at the sliding surfaces and enhanced with fluid viscous dampers, or (iii) triple friction pendulum bearings with low friction coefficients at the sliding surfaces. The paper demonstrates that the seismically isolated buildings designed per Section 17.3. 3 in ASCE/SEI 7‐16 standard, but with either increased isolator displacement capacity or increased superstructure strength by comparison to the minimum required, can achieve an acceptable collapse risk. It is also demonstrated that the seismic isolation systems that have the best collapse performance for far‐field motions are not necessarily the best for the near‐field pulse‐like ground motions.

Optimisation for offshore wind farm cable connection layout using adaptive particle swarm optimisation minimum spanning tree method

The wind farm layout optimisation problem is similar to the classic mathematical problem of finding the minimum spanning tree (MST) of a weighted undirected graph. Due to the cable current-carrying capacity limitation, the cable sectional area should be carefully selected to meet the system operational requirement and this constraint should be considered during the MST formulation process. Hence, traditional MST algorithm cannot ensure a minimal cable investment layout. In this study, a new method to optimise the offshore wind farm cable connection layout is presented. The algorithm is formulated based on the concept of MST and further improved by adaptive particle swarm optimisation algorithm. Since the location of the offshore substation (OS) has a significant impact on both the layout formulation and total cost of cables, the optimised location of OS is expected to be found together with the optimised cable connection layout. The proposed method is compared with the MST and dynamic MST methods and simulation results show the effectiveness of the proposed method.
Research on blank holder condition of FCF process for stepped-hole of sheet metal

Aiming at a flow control forming(FCF) process which was newly conceived,in utilization of DEFORM-3D software,numerical simulation of deformation on stepped-hole of sheet metal was carried out.The function of the blank holder force(BHF)as well as its influence on the forming performance and forming accuracy of combined stepped-hole were analyzed.A preferable blank holder condition for this FCF process,which used rigid blank holder,was proposed.The value of blank holder force is about half of forming pressure,namely Q=0.5 P.Moreover,the blank holder condition is validated by technological experiments using Al plate on hydroforming machine.
Prediction of protein secondary structure based on deep residual convolutional neural network

Abstract Proteins play a vital role in organisms, which suggests that in-depth study of the function of proteins is helpful to the application of proteins in a more accurate and effective way. Accordingly, protein structure will become the focus of discussion and research for a long time. In order to fully extract the effective information from the protein structure and improve the classification accuracy of the protein secondary sequence, a deep residual network model using different residual units was proposed to predict the secondary structure. This algorithm uses sliding window method to represent amino acid sequences and combines the powerful feature extraction ability of resent network. In this paper, the parameters of the neural network are debugged through experiments, and then the extracted features are classified and verified. The experimental results on CASP9, CASP10, CASP11 and CASP12 data sets imply that the improved deep residual network model based on different residual units can express amino acid sequences more accurately, which is more superior than existing methods.
The Recent Resurgence of Multiple-Use in the Swedish Forestry Discourse

Abstract Multiple-use forestry has gained increasing emphasis in forestry discourse in recent years. This article examines how multiple-use forestry has been perceived among Swedish forest actors. Halsey’s interpretation on ‘modalities of nature’ is used to address the tension and relations among various actors and the unfolding processes of becoming. Drawn on semi-structured interviews, we suggest seeing multiple-use forestry as a site for ideas and ideologies to collide, confluence and collaborate. We draw attention to interview materials that address the ‘modalities of nature’ where vision, naming, speed and affect all contribute to the becoming of multiple-use forestry. We thus show how multiple-use forestry has been used as a political concept and address the potentially creative and constructive relations generated by the forest users.
Effects of Repeated Ovarian Stimulation on Ovarian Function and Aging in Mice

Abstract Controlled ovarian hyperstimulation (COH) is routinely used in the in vitro fertilization and embryo transfer (IVF-ET) cycles to increase the number of retrieved mature oocytes. However, the relationship between repeated COH and ovarian function is still controversial. Therefore, we investigated whether repeated ovarian stimulation affects ovarian aging and function, including follicular development, autophagy, and apoptosis in follicles. Ovarian hyperstimulation in mice was induced by intraperitoneal injection with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG). Mice subjected to ovarian stimulation once were used as a control group and 10 times as an experimental group. Repeated injections with PMSG and hCG significantly reduced the number of primary follicles compared to a single injection. The number of secondary and antral follicles increased slightly, while the number of corpus luteum increased significantly with repeated injections. On the other hand, repeated injections did not affect apoptosis in follicles associated with follicular atresia. The expression of autophagy-related genes Atg5, Atg12, LC3B, and Beclin1, cell proliferation-related genes mTOR, apoptosis-related genes Fas, and FasL was not significantly different between the two groups. In addition, the expression of the aging-related genes Dnmt1, Dnmt3a, and AMH were also not significantly different. In this study, we demonstrated that repeated ovarian stimulation in mice affects follicular development, but not autophagy, apoptosis, aging in ovary. These results suggest that repetition of COH in the IVF-ET cycle may not result in ovarian aging, such as a decrease in ovarian reserve in adult women.
Shell-Sheddable Micelles Based on Poly(ethylene glycol)-hydrazone-poly[R,S]-3-hydroxybutyrate Copolymer Loaded with 8-Hydroxyquinoline Glycoconjugates as a Dual Tumor-Targeting Drug Delivery System

The development of selective delivery of anticancer drugs into tumor tissues to avoid systemic toxicity is a crucial challenge in cancer therapy. In this context, we evaluated the efficacy of a combination of nanocarrier pH-sensitivity and glycoconjugation of encapsulated drugs, since both vectors take advantage of the tumor-specific Warburg effect. Herein, we synthesized biodegradable diblock copolymer, a poly(ethylene glycol)-hydrazone linkage-poly[R,S]-3-hydroxybutyrate, which could further self-assemble into micelles with a diameter of ~55 nm. The hydrazone bond was incorporated between two copolymer blocks under an acidic pH, causing the shell-shedding of micelles which results in the drug’s release. The micelles were stable at pH 7.4, but decompose in acidic pH, as stated by DLS studies. The copolymer was used as a nanocarrier for 8-hydroxyquinoline glucose and galactose conjugates as well as doxorubicin, and exhibited pH-dependent drug release behavior. In vitro cytotoxicity, apoptosis, and life cycle assays studies of blank and drug-loaded micelles were performed on Normal Human Dermal Fibroblasts-Neonatal (NHDF-Neo), colon carcinoma (HCT-116), and breast cancer (MCF-7) for 24, 48, and 72 h. A lack of toxicity of blank micelles was demonstrated, whereas the glycoconjugates-loaded micelles revealed enhanced selectivity to inhibit the proliferation of cancer cells. The strategy of combining pH-responsive nanocarriers with glycoconjugation of the drug molecule provides an alternative to the modus operandi of designing multi-stimuli nanocarriers to increase the selectivity of anticancer therapy.
Musical play in girlhood: Transgenerational oral historical accounts

Musical play is a vital aspect of children’s musical cultures. As the social and cultural experiences of children change over time, their playful engagements with music may reflect these shifts. The purpose of this oral historical research was to explore girlhood musical play experiences over the course of a span of approximately 80 years (ca. 1920–2009), as well as the influences at work in the transmission, continuity, and content of these musical play behaviors. Semi-structured interviews were implemented to illuminate the musical play experience stories of 20 female individuals spanning four generations of birth as well as the factors impacting the transmission and continuity of musical play over time through family lines and across age cohorts. Findings suggest that influences of family, temporal context and peer groups, popular culture, cultural contexts, and issues of gender identity and gender roles were all present in the transmission of musical play repertoires over time. A lack of interest in musical play was also reported, which additionally impacted transmission.
Harmonized site preparation and postplant herbaceous weed control for establishment of southern pine plantations on coastal bedded sites

Abstract Loblolly pine or slash pine response and vegetation colonization are summarized for a region-wide study that included five locations on coastal soils in the southern United States. The objective was to evaluate timing of postplant herbaceous weed control (HWC) treatments following preplant site preparation with imazapyr applied at two timings (August and November) and at three rates (0.56, 0.84, and 1.12 kg ha–1). All imazapyr site preparation treatments were applied after bedding. Site preparation treatments resulted in fast-growing stands without HWC at all locations with average Year 3 dominant tree height ranging from 2.6 to 3.7 m. Imazapyr plus sulfometuron was an effective HWC treatment on loblolly pine. Vegetation control and pine response varied by surface soil texture. On coarser-textured soils, the site preparation treatments resulted in <10% vegetation cover in June of the first pine growing season. On these coarser-textured soils, loblolly pine growth was increased by second-year and not first-year HWC. On finer-textured soils, vegetation colonization was aggressive, with >20% cover in June of the first pine growing season, such that early first-year HWC provided the largest loblolly pine response of single-pass HWC treatments. Pines were highly tolerant to imazapyr site preparation treatments as evidenced by the lack of differences in slash or loblolly pine survival and growth from the doubling of imazapyr rates for applications in either August or November. There was little meaningful residual control of herbaceous vegetation into the second pine growing season from site preparation treatments or first-year HWC regardless of location. There was no consistent pine response benefit from increasing the imazapyr site preparation rate for included treatments. Cost-effective treatments would utilize low site-preparation herbicide rates followed by the appropriate timing of HWC if longer-term vegetation control is the objective. Nomenclature: Imazapyr; sulfometuron; loblolly pine; Pinus taeda L. ; slash pine; Pinus elliottii Engelm.
Radiation Field Inside the Homogeneous Moon Excited by a Vertical Magnetic Dipole

The investigation of radiation field in the moon is important for the moon subsurface detection and vertical magnetic dipoles (VMD) are especially useful as sources and probes. The present work focuses on the radiation field inside the moon excited by a VMD located on or near the moon’s surface. Analytical expressions are derived with approximate method. Contributions of the fields come from two parts: the series expansions of low-order terms using the multiplication iteration method, and the integrals of high-order terms using the asymptotic method. Meanwhile, the field of high-order terms is close to the total field. Compared with the calculation’s direct sum, our method has advantages of accuracy and is suitable for the large-size model. For a source-receiver system on or near the homogeneous moon, it is found the waves propagating inside the moon can be described in terms of ray optics. Based on the formulas, various modes of reflection are taken into account, and the intensity of the primarily reflected waves is calculated numerically. Furthermore, effects of propagation distance and angel, the operating frequency, as well as the height of the source are considered to demonstrate the properties of the field. Particularly, the proposed method and formulas have applications to the moon interior exploration.
A review of manufacturing flexibility: systematising the concept

The present work is an attempt to contribute to the conceptual systematisation of the manufacturing flexibility types by synthesising the vast literature available after a systematic review. We classified the papers in two perspectives (hierarchical and strategic), and engaged in a systematic process of standardisation of the definitions and names of various flexibility types leading to a better understanding of them. This process allowed us to clearly show: (a) the existence of a broader consensus in the field than expected; (b) that problems are limited to concrete aspects related to the level of analysis or the scope of certain flexibility types; (c) the possibility of a theoretical integration between the two perspectives which would permit a standardisation of the names and definitions for the flexibility types which make up the manufacturing flexibility construct.

Zhoushan multi-terminal VSC-HVDC project will be the first DC transmission project with five converter stations in the world which is based on modular multilevel converter(MMC) technology. To study the overvoltage of each converter station,overvoltage mechanism of AC and DC switchyard are analyzed in detail based on this project, and overvoltage levels in typical faults such as single-phase-to-ground fault at the valve side of converter transformer and at the valve side of converter reactor, DC pole line ground fault, ground fault at the valve side of DC smoothing reactor and DC to DC pole line fault are calculated based on the MMC-HVDC model with five stations. Results show that the maximum overvoltage for AC bus at the valve side of converter transformer is 360 kV; the maximum overvoltage for DC bus at the line side and at the valve side of the DC smoothing reactor are370 kV and 369 kV respectively; the maximum overvoltage of the neutral point of star reactance grounded branch and converter reactor are 188 kV and 235 kV respectively; the maximum energy of arrester CB and D are 1.258 MJ and 1.655 MJ respectively. The research results will provide important basis for the insulation coordination of station devices.
“Immigration Enforcement Is a Daily Part of Our Students’ Lives”: School Social Workers’ Perceptions of Racialized Nested Contexts of Reception for Immigrant Students

This qualitative analysis examines school social workers’ equity work for immigrant students, including their perceptions of immigration enforcement and school climates that support or hinder immigrant student experiences. We conceptually expand understandings of nested contexts of reception and racialized organizations across macro, meso, micro levels, and how they affect immigrant students’ educational experiences, mobility, and belonging. Utilizing open-ended responses from a unique national survey data set, we examine school social workers’ perceptions of the macro, meso, micro racialized contexts that immigrant students encounter, how school social worker perceptions reflect racial attitudes as part of the racialized organization of schools in which they work, and how such racial attitudes influence their actions and potentially disrupt racial inequality in schools. Discussion of the impact of school social workers’ racial attitudes, and perceptions of racialized contexts and how they influence school social workers’ advocacy for immigrant students is offered.
Flexible Mobility Models Using Stochastic Differential Equations

We develop a family of tractable models for UAV mobility. Based on a system of coupled stochastic differential equations, the resulting models exhibit realistic trajectories and flexible covariance structures, making them suitable for both small scale and large scale applications. Closed form solutions for steady state and transient position distributions, as well as position covariance, are derived. These results are subsequently used to obtain distance outage probabilities and pathloss. The analytical results allow us to assess the impact of a variety of system parameters related to device control, navigation and position measurement errors. Finally, using measured UAV flight data, we show an excellent goodness of fit between the proposed model and the data.
Patent citing patterns of foreign firms: an analysis of Indian IT services industry

ABSTRACT This study captures the origin and pattern of foreign knowledge inflows to the Indian IT services industry using patent citation data. It examines the patterns of backward patent citations by the US origin and non-US origin foreign IT services firms operating in India using the USPTO patent citation data from 2013 to 2017. To analyze the citing patterns of firms, we classified backward citations into two categories: self-citations and non-self-citations. Our study finds that patents granted to the US origin firms hold a relatively higher number of backward citations and a higher average number of inventors. It indicates that the Indian IT services industry receives more complex technology inflows from the US origin firms compared to non-US origin firms. It also shows a positive relationship between self-citations and lowers patent grant lag. Further, this study suggests that more self-citations by the US origin firms reinforce more patents that develop a patent cycle for a firm. Therefore, the US origin firms in the Indian IT services industry dominate in patenting activities at USPTO.

Achieving Long Distance Sensing Using Semiconductor Laser with Optical Feedback by Operating at Switching Status

In this study, a novel distance sensing method is presented by using a semiconductor laser (SL) with optical feedback (OF) and operating the SL at a switching status happened between two nonlinear dynamic states (stable state and period-one state). In this case, without the need for any electronic or optical modulation devices, the laser intensity can be modulated in a square wave form due to the switching via utilizing the inherent SL dynamics. The periodicity in the switching enables us to develop a new approach for long-distance sensing compared to other SL with OF-based distance measurement systems and lift the relevant restrictions that existed in the systems. Moreover, the impact of system controllable parameters on the duty cycle of the square wave signals generated was investigated on how to maintain the proposed system robustly operating at the switching status. Both simulation and experiment verified the proposed sensing approach.
