description: Context: 3C 273, a well-studied active galactic nucleus (AGN), displays characteristics of both jetted-AGN and Seyfert galaxies, making it an excellent source to study the disc-jet connection in AGN. Aims: To investigate the disk-jet scenario in 3C 273 using broadband (0.3--78 keV) X-ray spectra from {\it XMM-Newton} and {\it NuSTAR}. Methods: We used simultaneous {\it XMM-Newton} and {\it NuSTAR} observations of 3C 273 carried out between 2012 and 2024. The 0.3--78 keV X-ray spectra were first fit with a simple power-law (PL) and then with the accretion-ejection-based JeTCAF model. The JeTCAF model accounts for emission from the jet, extending up to the sonic surface. In this framework, a reflection hump above 10 keV can also arise due to the bulk motion Comptonization of coronal photons by the jet. Results: We found that the simple PL did not provide a good fit, leaving significant residuals at energies below 1.5 keV. All the spectra were fitted well by the JeTCAF model. The weighted-averaged black hole mass of (7.77$\pm$0.30) $\times 10^8 M_\odot$ obtained from the JeTCAF model is comparable with the previous estimates based on reverberation mapping observations and accretion disk models. Conclusions: The 0.3--78 keV X-ray emission of 3C 273 can be fit by the accretion-ejection-based model in which the corona and the jet on top of it make significant contributions to the X-ray flux. The Doppler boosting factor estimated from the jet flux ranges from 1.6 to 2.2, consistent with the lower limit from the literature.

description: This dissertation addresses 12 questions related to an overall investigation
designed to determine if there is a relationship between teacher perceptions of
professional development and student achievement in rural Maryland. During an era of
federal, state, and local education reform, lessons learned could help dramatically
redesign professional development for the future. “Pedagogical Content Knowledge”
(PCK) coined in 1986 by Lee Shulman, a past president of the Carnegie Foundation for
the Advancement of Teaching, and the 1995 book written by Stephen Brookfield
Becoming a Critically Reflective Teacher helped to form the conceptual framework of
this study.

Twelve elements relating to professional development were part of the questions
on the Teaching, Empowering, Leading, and Learning (TELL) Maryland Survey of 2011
and 2013. The change in these TELL Maryland Survey teacher perceptions was
correlated with the change in student High School Assessment (HSA) senior exit exam
results for the same time period. Data were included from 79% (11,365 of 14,368) of
teachers in 80% (63 of 79) of all rural high schools in Maryland that reported HSA senior
exit exam data and responded at a 50% or higher rate on both studied years of the TELL Maryland Survey.

After analyzing statewide data, disaggregated by five regions, it was determined
that three professional development elements had positive correlations and nine had
negative correlations, although none of these were statistically significant. Those
elements that correlated most positively with student achievement (with shortened titles
used in the study) were collaboration, reflect(ion), and time. The literature review
provided insight into some possible reasons for these results.

description: Introduction and purpose: Balancing is recognized as one of the most important challenges in the aging period. The purpose of the present study was to determine the effect of dual and single task training on the balance traits of male elderly people. Materials and methods: Twenty elderly subjects who were available and qualified were selected and randomly divided into two groups of 10, including a walking practice group in dual homework conditions and a single practice group. The dual task team performed a specific cognitive task for each individual while walking, and the other group was practicing routine walking. In the pre-test and post-test phases, the selected kinematic parameters of the selected step were measured using the ZBIS analyzer, which included: step width, step length, dual retention percentage, track, velocity, and velocity changeability. The groups performed exercises for 8 weeks, 3 sessions each 60 minutes a week. Findings: The results of statistical analysis of repeated measuers ANOVA (2 × 2) with intra-group time (before and after training) and the inter-group type of exercise showed a significant intra-group effect. Also a significant different was found between groups in mentioned parameters More analysis revealed the intra-group effect for dual task group for step length parameters, dual stance time, tracks, speed, and velocity variability (P≤0.05). This effect was not seen on the step width (P> 0.05). Also a significant different was found between groups in mentioned parameters Conclusion: Walking exercises in dual cognitive situations can improve some of the parameters of the step-up in relation to the balance of male elderly.

description: Zeolites are fascinating crystalline aluminosilicates known for their unique microporous structure and impressive ion exchange capabilities, which make them incredibly useful across a variety of fields. This review takes a closer look at the essential features of zeolite structure, composition, and the mechanisms behind ion exchange. The core of zeolites, you`ll find a fascinating structure of interconnected tetrahedra composed of silicon and aluminum, all nicely balanced by exchangeable cations such as sodium, calcium, and potassium. The review dives into the factors that affect ion exchange properties, such as the size and charge of the ions, the specific zeolite structure, temperature, and the makeup of the solution. It also emphasizes theion exchange capacity (IEC) and selectivity of zeolites, showcasing their importance in areas like water treatment, agriculture, catalysis, and biomedical engineering. A comparison between natural and synthetic zeolites is made, with synthetic options providing more control over their composition and structure. Recent advancements in zeolite synthesis are also explored, highlighting methods like mechanochemical techniques, zeolite-polymer composites, and zeolite membranes, along with their potential applications in CO2 capture and gas separation. Despite facing challenges such as mass transfer limitations and high synthesis costs, zeolites remain vital in numerous industries, with ongoing research opening doors for future innovations.

description: In a superconductor electrons form pairs despite the Coulomb repulsion as a result of an effective attractive interaction mediated by, for example phonons. In the present paper DeGennes' description of the dynamically screened Coulomb interaction is adopted for the effective interaction. This model is generalized by including the elastic response of the charge-compensating background and the BCS gap equation is solved for the resulting effective electron-electron interaction. It is demonstrated that the superconducting critical temperature becomes strongly enhanced when the material is tuned close to a structural instability.

description: On 13 March 2023, when the Parker Solar Probe was situated on the far side of the Sun as seen from Earth, a large solar eruption took place creating a strong solar energetic particle (SEP) event observed by multiple spacecraft (S/C). The energetic event was observed at six well-separated locations: Parker Solar Probe, Solar Orbiter, BepiColombo, STEREO~A, near-Earth S/C, and MAVEN. An in-situ shock crossing and a related energetic storm particle (ESP) event were observed at all inner-heliospheric S/C, suggesting that the interplanetary coronal mass ejection (CME)-driven shock extended all around the Sun. However, the solar event was accompanied by a series of pre-event CMEs. We aim to characterize this extreme widespread SEP event and to provide an explanation for the unusual observation of a circumsolar interplanetary shock and corresponding circumsolar ESP event. We analyse data from seven space missions to characterize the solar eruption at the Sun, the energetic particle event, and the interplanetary context at each observer location as well as the magnetic connectivity of each observer to the Sun. We employ magnetohydrodynamic simulations of the solar wind in which we inject various CMEs that were launched before as well as contemporaneously with the solar eruption under study. In particular, we test two different scenarios that could have produced the observed global ESP event: 1) a single circumsolar blast-wave-like shock launched by the associated solar eruption, and 2) the combination of multiple CMEs driving shocks into different directions. By comparing the simulations of the two scenarios with observations we find that both settings are able to explain the observations. However, the blast-wave scenario performs slightly better in terms of the predicted shock arrival times at the various observers.

description: Diabetes mellitus is a chronic metabolic condition requiring continuous medical care and patient selfmanagement, where nutritional awareness plays a central role. This study aimed to assess the level of nutrition awareness among hospitalized diabetic patients in Apollo Hospital, Indore. A sample of 50 patients aged 30– 70 years was selected using random sampling to ensure representation across educational and socioeconomic backgrounds. The study evaluated their demographic characteristics, biochemical parameters, and awareness related to diabetes management, particularly focusing on dietary knowledge. Results revealed that while a significant proportion of participants (90%) acknowledged the importance of diet in diabetes control, only 52% were aware of complications related to uncontrolled diabetes. Additionally, 72% could identifyhypoglycemia symptoms, 60% regularly used a glucometer, and 84% monitored blood glucose levels. However, only 8% understood the concept of the glycemic index, highlighting a critical gap in essential nutritional knowledge. Biochemical parameters showed that 76% had controlled HbA1c levels, while 24% presented with anemia. Moreover, 82% of participants reported comorbidities such as hypertension and kidney issues, indicating the broader health burden faced by diabetic patients. The study underscores the need for structured, in-hospital nutrition education programs tailored to diabetic patients. Improving awareness about glycemic control, meal planning, and disease complications during hospitalization can lead to better selfmanagement and long-term outcomes.

description: Review Buku Structural Anthropology, Claude Levi-Strauss

"Structural Anthropology” adalah sebuah buku yang ditulis oleh Claude Lévi-Strauss, seorang antropolog terkemuka dari Prancis. Buku ini pertama kali diterbitkan di Prancis pada tahun 1958 dan kemudian diterjemahkan ke dalam bahasa Inggris. Buku ini merupakan kumpulan dari tujuh belas makalah yang ditulis antara tahun 1944 dan 1957, yang dianggap oleh Lévi-Strauss sebagai karya paling representatifnya.

Dalam buku ini, Lévi-Strauss bertujuan untuk menunjukkan bagaimana metode struktural dapat diterapkan pada berbagai aspek budaya, seperti kekerabatan, bahasa, mitos, dan seni. Lévi-Strauss (1963) berpendapat bahwa dengan menganalisis hubungan antara unit-unit dasar dalam suatu sistem budaya, antropolog dapat mengungkap prinsip-prinsip universal yang mengatur pemikiran dan perilaku manusia.

Review Buku Argonauts of the Western Pacific, Bronislaw Malinowski

"Argonauts of the Western Pacific" merupakan karya etnografi monumental karya Bronislaw Malinowski, diterbitkan pertama kali pada tahun 1922. Buku ini mendokumentasikan kehidupan masyarakat Kepulauan Trobriand (sekarang bagian dari Papua Nugini) dan memperkenalkan pendekatan observasi partisipatif sebagai metode utama dalam penelitian antropologi lapangan. Malinowski berpendapat bahwa untuk memahami suatu budaya, seorang antropolog harus terjun langsung ke lapangan, tinggal bersama masyarakat yang diteliti untuk waktu yang lama, mempelajari bahasa mereka, berpartisipasi dalam kegiatan sehari-hari, dan membangun hubungan yang mendalam dengan mereka.
Holy Henries : the first Tudor and the cult of the last Lancastrian
Creators: name: Labun, Katrina
Publisher: name: The University of British Columbia
Year: 2014

description: Throughout most of his reign, Henry VII of England was engaged in intermittent negotiations with the papacy regarding the canonization of his predecessor, Henry VI, as a saint. Henry VI, who had been murdered in 1471 by agents of Edward IV, was one of the most popular saints in England at the time, but Henry VII’s campaign for his official canonization eventually failed. While many historians have seen this campaign as motivated by Henry VII’s cynical political opportunism, I argue that in this matter Henry VII’s political aims cannot be understood as separate from his Christian piety. Contrary to his popular portrayal as the ultimate political manipulator, Henry VII was in fact a deeply pious man. His piety was very much informed by his upbringing in France and Brittany and by the pervasive late-medieval cult of holy monarchy. Medieval kings were believed to have a religious as well as a political role, and Henry VII demonstrated a strong interest in the sacral nature of his kingship. The cult of Henry VI also promoted the role of a divinely appointed king in establishing reconciliation and harmony, which accorded well with Henry VII’s objective to restore peace and piety in England following the Wars of the Roses. The campaign for Henry VI’s canonization thus can only be properly understood within its own cultural sensibility, and within the context of Henry VII’s piety and ideology of his reign as a whole.
Variations in wetting angles for carbonate-silicate melts
Creators: name: Huang, Katherine
Publisher: name: The University of British Columbia
Year: 2015

description: The sessile drop method was used to measure the wetting angles of carbonate-silica melt droplets as a proxy for surface tension. Melts were synthesized by sintering pure anhydrous Na₂CO₃ powder with SiO₂ powder. The final weight percentages of Na₂O, SiO₂, and CO₂ of each melt were calculated. Samples of approximately 0.03g of each melt composition were melted on a substrate of alumina at 1000°C until the droplets had fully relaxed. The droplets were quenched at room temperature and wetting angle measurements were taken. Droplets of melt compositions of 62 wt% SiO2 and less produced wetting angles of 3 to 9°. Droplets of melt composition of 71 wt% produced drastically higher wetting angles of 23°. These results indicate that SiO₂ content does not significantly affect the wetting angle of the Na₂SiO₃- SiO₂ system until SiO₂ composes 71 wt% of the of the melt composition. The phase diagram of the SiO₂-Na₂CO₃ system is used to estimate the varying amounts of liquid and solid Na₂CO₃, solid Na₂SiO₃, liquid Na₂Si₂O⁰₅, and solid SiO₂ in each melt. Due to its molecular structure and high number of non-bridging oxygens/tetrahedral (NBO/T) Na₂CO₃ likely is the controlling component of the surface tension of the melts below 71 wt% SiO₂. Once the melt composition exceeds 62 wt% SiO₂,, Na₂Si₂O₅ controls the surface tension of the melt via the introduction of a bridging oxygen that affects the interactions between the liquid molecules and increases the wetting angle.

description: The aim of this study was to investigate the effect of 12 weeks walking training on cobblestone mats on spatio-temporal parameters for the elderly women. Twenty community-dwelling elderly women, aged 65-80, eligible to participate in the study, were randomly allocated to an experimental group (n=10) or a control group (n=10). Experimental group trained walking on artificial cobblestone-mats for 12 weeks, 3 sessions per week. Zebris Gait Analyzing System was used for measuring Balance indices during gait in pre and posttests. Mixed ANOVA test revealed a significant effect of time-group interaction (P<0.05). We used the paired samples T test to compare the mean test scores before (pre-test) and after (post-test) intervention in each group. Independent t test was also used to evaluate the differences in means between experimental and control groups in pre and posttest. Results showed a significant difference between pre and posttests mean scores of cadence, stride length, gait velocity, variability of velocity for experimental group (P<0.05) not in control group (P>0.05).Between group analysis showed that there were significant differences between posttest mean scores in two groups in cadence, stride length, gait velocity and variability of velocity (P<0.05).We concluded the 12 week walking training on artificial cobblestone-mat effects on risk factors of falls during walking in elderly.
Effects of community-based natural resource management on household welfare in Namibia

description: Biodiversity conservation, as an environmental goal, is increasingly recognized to be connected to the socioeconomic well-being of local communities. The development of a widespread community-based natural resource management (CBNRM) program in Namibia makes it an ideal location to analyze the connection between conservation and socioeconomic well-being of local communities. Namibia’s CBNRM program involves the formation of communal conservancies within rural communities and is typically considered a success on both ecological and economic fronts. In order to broaden the understanding of the program’s impact to include social factors, we have conducted a comparative analysis to determine the effects of this program on household welfare outcomes. Data from two rounds of the Namibia Demographic and Health Surveys (2000 and 2006/07) and quasiexperimental statistical methods were used to evaluate changes in various health, education and wealth outcomes of those living in conservancies, relative to non-conservancy comparison groups. Regression results indicate mixed effects of the conservancy program at the household level. The program had positive effects on some health outcome variables, including bednet ownership, which was twice as likely to increase over time in conservancy compared to non-conservancy households. Program impacts were negative for education outcomes, with the proportion of school attendance of conservancy children being 45% less likely to increase over time than non-conservancy children. Wealth outcome results were inconclusive. Our findings highlight the importance of analyzing community conservation programs at the household level when evaluating overall impact, as community benefits do not necessarily extend down to the household level. We recommend further analysis of this program, as an extended time period, more outcome variables and larger sample sizes would provide a valuable addition to this analysis.

description: Abstract Purpose: The improvement of cognitive and motor components and sports performance evaluation process is important in game-based approaches. This study aimed to standardize the game performance evaluation tools (G-PET) in football schools in Iran. Method: However, 48 experienced and novice players of soccer schools in children, adolescents, and young adult age categories (all groups included 8 experienced and 8 novice players) played 3×3 football game with the keeper was in a small field with dimensions of 25×35 m. Using digital camera and in the height of 5 meters above the playground, the games were captured and coded using G-PET. Consulting with 6 specialists and physical education instructors to delete and modify some behavioral descriptions, the content validity Index (CVI) of this tool in offensive behavior of on and off the ball players was 0.99. For assessing the intra-observer reliability, one of the game videos was randomly selected and two observers’ perceptions were evaluated at an interval of 2 weeks. Findings: There was positive correlation among the results of tactical appropriate behaviors including ball possession, attacking the opponent's goal, and scoring. The coding of two observers for the video was compared to evaluate the interobserver reliability. The one-way ANOVA results showed that there is no significant difference between the two observers in terms of tactical and technical variables. Describing accurately the offensive behaviors in football, the G-PET tool helps coaches and instructors to evaluate the offensive behavior of on and off the ball football learners according to tactical situation at that moment

The purpose of the present study was to determine the effect walking training with increased cognitive load on gait traits related to balance in elderly males. Materials and methods: 20 elderly subjects who were available and qualified were selected and randomly divided into two groups of 10, including a walking training group in increased cognitive load conditions by dual task and a single task group. The increased cognitive load group performed a specific cognitive task while walking, and the other group was trained normal walking. Zebris Gait Analyzing System was used for measuring gait traits including, step width, stride length, gait velocity, double support time percentage, cadence and variability of velocity percentage in pre and posttests. The groups trained for 8 weeks, 60 minutes, 3 sessions per week. Data were analyzed by repeated measuers ANOVA (2× 2) and SPSS22. Findings: The results of statistical analysis of repeated measurers ANOVA (2× 2) showed a significant intra-group effect. More analysis revealed the intra-group effect in increased cognitive load group for stride length, double support time percentage, cadence, gait velocity, and variability of velocity (P≤ 0.05). This effect was not seen on the step width (P> 0.05). Also a significant different was found between groups in the parameters. Conclusion: Walking exercises in dual cognitive situations can improve some of the parameters of the step-up in relation to the balance of male elderly.

description: The aim of this study was to investigate the relationship of force control and adjustment of dominant hand’s angle to selected psychological traits in athlete and non-athlete students. 120 participants including 99 male and 21 female athlete students (19-29 years old) from different sports and 120 non-athlete students from Tehran university (20 girls, 100 boys) attended in the study. Digital handgrip device and angle joint measurement device were used respectively to assess force reproduction and joint reposition. Profile of Mood States Questionnaire was used to measure mood states and to measure emotional intelligence we used Schutte’s emotional intelligence scale. To evaluate relationship between variables Pearson's correlation coefficient was used. The Z-Fisher was used for investing difference between correlation coefficients. The results showed that there was a significant relationship between POMS’s scores with force control and adjustment of dominant hand’s angle errors in both groups, although the relationship was stronger in nonathletic subjects. The findings indicated that negative mood states can lead to kinesthesis sense errors, but that is less effective in athletes. On the other hand, that there was not significant relationship between EQ’s scores with force control and adjustment of dominant hand’s angle errors in both groups, i.e. kinesthesis sense cannot be affected by cognitive control of emotion and longtime sport participation does not affect on their relationship.

description: Despite widespread kratom use, there is a lack of knowledge regarding its effects on driving. We evaluated the self-reported driving behaviors of kratom consumers and assessed their simulated-driving performance after self-administering kratom products. We present results from: 1) a remote, national study of US adults who regularly use kratom, and 2) an in-person substudy from which we re-recruited participants. In the national study (N = 357), participants completed a detailed survey and a 15-day ecological momentary assessment (EMA) that monitored naturalistic kratom use. For the remote study, outcomes were self-reported general and risky driving behaviors, perceived impairment, and driving confidence following kratom administration. For the in-person substudy, 10 adults consumed their typical kratom products and their driving performance on a high-fidelity driving simulator pre- and post-kratom administration was evaluated. Over 90% of participants surveyed self-reported driving under the influence of kratom. Most reported low rates of risky driving behavior and expressed high confidence in their driving ability after taking kratom. This was consistent with EMA findings: participants reported feeling confident in their driving ability and perceived little impairment within 15-180 min after using kratom. In the in-person substudy, there were no significant changes in simulated driving performance after taking kratom. Using kratom before driving appears routine, however, self-reported and simulated driving findings suggest kratom effects at self-selected doses among regular kratom consumers do not produce significant changes in subjective and objective measures of driving impairment. Research is needed to objectively characterize kratom’s impact on driving in regular and infrequent consumers.

description: In this paper I discuss the specification of self-selection models with random parameters. I demostrate that in a self-selection model, misspecification of the parameter structure as constant causes blased estimates, and the direction of the bias leads to an under-estimation of the selectivity effect. I estimate a self-selection model of moonlighting with random parameters and find that: the selectivity effect, which was almost absent in the constant parameter version of the model, is indeed significant.

description: Using the Large Millimeter Telescope and the SEQUOIA 3~mm focal plane array, we have searched for molecular line emission from two atomic clouds associated with the Fermi Bubble of the Milky Way. Neither 12CO nor 13CO J=1-0 emission is detected from the HI cloud, MW-C20. 12CO J=1-0 emission is detected from MW-C21 that is distributed within 11 clumps with most of the CO luminosity coming from a single clump. However, we find no 13CO emission to a 3sigma brightness temperature limit of 0.3 K. Using this limit and RADEX non local thermodynamic equilibrium (non-LTE) excitation models, we derive H2 column density upper limits of (0.4-3)x10^{21} cm-2 for a set of physical conditions and a H2 to 12CO abundance ratio of 10^4. Model CO-to-H2 conversion factors are derived for each set of physical conditions. We find the maximum value is 1.6x10^{20} cm-2/(K km/s). Increasing [H2/12CO] to 10^5 to account for photodissociation and cosmic ray ionization increases the column density and XCO upper limits by a factor of 10. Applying these XCO limits to the CO luminosities, the upper limit to the total molecular mass in MW-C21 is 132+/-2~Msun, corresponding to less than 27% of the neutral gas mass. For the three clumps that are fully resolved, lower limits to the virial ratios are 288+/-32, 68+/-28, and 157+/-39, which suggest that these structures are bound by external pressure to remain dynamically stable over the entrainment time of 2x10^6 years or are being disrupted by shear and expansion over the clump crossing times of (3-8)x10^5 years. The observations presented in this study add to the growing census of cold gas entrained within the Galactic Center wind.

description: Objective: Motor skill learning is one of the main problems of children with developmental coordination disorder (DCD). Since the prevalence of this disorder among children is considerable, thus this study carried out for determine the frequency of feedback about knowledge of result (KR) on throwing skill’s motor learning in children with DCD. Methods: This study was semi-experimental study with pretest-posttest design. The study populations were DCD children 7 to 9 years’ old boys and girls who lived in district 1 & 2 of Tehran that among these population, 30 children were participated after make sure to study inclusion criteria by Convenience Sampling. Data were collected with DCDQ'7 diagnostic questionnaire and Chiviacowsky accuracy of Children throwing. Data were analyzed by paired sample t-test, ANOVA and LSD post hoc test. Results: Feedback based on KR 100% and 50% were effective on motor learning in DCD children (p= 0.001). But the relative feedbacks with 50% frequency of KR lead to better than 100% on motor learning in throwing skill (p< 0.001). Conclusion: The present study confirms the guidance hypothesis feedback and suggests that 50% KR frequent feedback lead to enhanced learning in children with developmental coordination disorder.

description: A lower helmet-wearing rate and overspeeding in Pakistan are critical risk behaviors of motorcyclists, causing severe injuries. To explore the differences in the determinants affecting the injury severities among helmeted and non-helmeted motorcyclists in motorcycle crashes caused by overspeeding behavior, single-vehicle motorcycle crash data in Rawalpindi city for 2017–2019 is collected. Considering three possible crash injury severity outcomes of motorcyclists: fatal injury, severe injury and minor injury, the rider, roadway, environmental, and temporal characteristics are estimated. To provide a mathematically simpler framework, the current study introduces parsimonious pooled random parameters logit models. Then, the standard pooled random parameters logit models without considering temporal effects are also simulated for comparison. By comparing the goodness of fit measure and estimation results, the parsimonious pooled random parameters logit model is suitable for capturing the temporal instability. Then, the non-transferability among helmeted and non-helmeted overspeeding motorcycle crashes is illustrated by likelihood ratio tests and out-of-sample prediction, and two types of models provide robust results. The marginal effects are also calculated. Several variables, such as age, cloudy and weekday indicators illustrate temporal instability. Moreover, several variables are observed to only show significance in non-helmeted models, showing non-transferability across helmeted and non-helmeted models. More educational campaigns, regulation and enforcement, and management countermeasures should be organized for non-helmeted motorcyclists and overspeeding behavior. Such findings also provide research reference for the risk-compensating behavior and self-selected group issues under overspeeding riding considering the usage of helmets.

description: Occupant impact safety is critical for train development. This paper proposes a systematic procedure for developing validated numerical occupant crash scenarios for high-speed trains by integrating experimental, computational, and inverse methods. As the train interior is the most potentially injury-causing factor, the material properties were acquired by mechanical tests, and constitutive models were calibrated using inverse methods. The validity of the seat material constitutive model was further verified via drop tower tests. Finite element (FE) and multibody (MB) models of train occupant-seat interactions in frontal impact were established in LS-DYNA and MADYMO software, respectively, using the experimentally acquired materials/mechanical characteristics. Three dummy sled crash tests with different folding table and backrest configurations were conducted to validate the numerical occupant-seat models and to further assess occupant injury in train collisions. The occupant impact responses between dummy tests and simulations were quantitatively compared using a correlation and analysis (CORA) objective rating method. Results indicated that the experimentally calibrated numerical seat-occupant models could effectively reproduce the occupant responses in bullet train collisions (CORA scores >80%). Compared with the train seat-occupant MB model, the FE model could simulate the head acceleration with slightly more acceptable fidelity, however, the FE model CORA scores were slightly less than for the MB models. The maximum head acceleration was 30 g but the maximum HIC score was 17.4. When opening the folding table, the occupant’s chest injury was not obvious, but the neck-table contact and “chokehold” may potentially be severe and require further assessment. This study demonstrates the value of experimental data for occupant-seat model interactions in train collisions and provides practical help for train interior safety design and formulation of standards for rolling stock interior passive safety.
The integration of the Chinese market gardens of southern British Columbia, 1885-1930

description: This article examines the history of Chinese integration into the small-scale hand-cultivation of a variety of fruits and vegetables grown for local consumption, otherwise known as market gardening, in Southern British Columbia. Racism and discriminatory regulations restricted employment opportunities and relegated the Chinese to occupations deemed ‘menial’ – market gardening, domestic service, and peddling. As the Chinese presence grew within these ‘menial’ occupations, the interrelated relationships between such occupations reinforced one another to allow for the Chinese to achieve market dominance in market gardening by the 1920s. Despite opposition from Euro-Canadians expressed through restrictive regulations on the agricultural trade, the supporting occupations of domestic service, peddling, and green grocer and the formation of associations had coalesced by the late 1920s to entrench the Chinese into a solidified position in the market gardening industry.
