Abstract (sommario):
An experimental trial was conducted in triplicate to determine the effect of different salinity levels 0 (SA0), 2(SA2), 4(SA4), 6(SA6), 8(SA8) and 10 (SA10) ppt on survival, behaviour, and morphological changes in mrigal, Cirrhinus mrigala fingerlings during short-term rearing in inland saline water in glass aquaria for 10 days. Healthy fingerlings (average length-11.18 cm, average weight-11.05 g) of mrigal, procured from the Instructional cum Research Farm, College of Fisheries, were conditioned for one week at 0 ppt (freshwater) in FRP pools and conditioned fingerlings were gradually acclimated to varying salinities by raising the salinity by 1 ppt hourly and then stocked into glass aquaria of respective salinity levels @ 10 fingerlings aquarium-1. Predetermined salinity levels and the water level were maintained in all the treatments and fish were fed with pelleted feed (crude protein 26.12%) @ 0.5% of fish body weight, once a day, as sustenance ration throughout the experimental period. The results indicated that all the water quality parameters, except temperature, varied significantly (P0.05) across treatments. Furthermore, no fish mortality occurred up to 6 ppt salinity during the experiment. In contrast, survival rates were 93.33% and 86.67% at 8 and 10 ppt salinity, respectively at the termination of the experiment. Normal swimming and feeding (feed intake) behaviour were recorded up to 6 ppt, whereas no adverse morphological changes were observed in fish during the tolerance test in all the treatments. From the above results, it can be concluded that mrigal, C. mrigala can tolerate salinity up to 6 ppt during short term (10 days) rearing in inland saline water.

Abstract (sommario):
Basic fibroblast growth factor 2 (bFGF) accelerates bone formation during fracture healing. Because the efficacy of bFGF decreases rapidly following its diffusion from fracture sites, however, repeated dosing is required to ensure a sustained therapeutic effect. We previously developed a fusion protein comprising bFGF, a polycystic kidney disease domain (PKD; s2b), and collagen-binding domain (CBD; s3) sourced from the Clostridium histolyticum class II collagenase, ColH, and reported that the combination of this fusion protein with a collagen-like peptide, poly(Pro-Hyp-Gly)10, induced mesenchymal cell proliferation and callus formation at fracture sites. In addition, C. histolyticum produces class I collagenase (ColG) with tandem CBDs (s3a and s3b) at the C-terminus. We therefore hypothesized that a bFGF fusion protein containing ColG-derived tandem CBDs (s3a and s3b) would show enhanced collagen-binding activity, leading to improved bone formation. Here, we examined the binding affinity of four collagen anchors derived from the two clostridial collagenases to H-Gly-Pro-Arg-Gly-(Pro-Hyp-Gly)12-NH2, a collagenous peptide, by surface plasmon resonance and found that tandem CBDs (s3a-s3b) have the highest affinity for the collagenous peptide. We also constructed four fusion proteins consisting of bFGF and s3 (bFGF-s3), s2b-s3b (bFGF-s2b-s3), s3b (bFGF-s3b), and s3a-s3b (bFGF-s3a-s3b) and compared their biological activities to those of a previous fusion construct (bFGF-s2b-s3) using a cell proliferation assay in vitro and a mouse femoral fracture model in vivo. Among these CB-bFGFs, bFGF-s3a-s3b showed the highest capacity to induce mesenchymal cell proliferation and callus formation in the mice fracture model. The poly(Pro-Hyp-Gly)10/bFGF-s3a-s3b construct may therefore have the potential to promote bone formation in clinical settings.

Abstract (sommario):
Myocardial infarction has a high mortality rate worldwide. Therefore, clinical intervention in cardiac remodeling after myocardial infarction is essential. Açai pulp is a natural product and has been considered a functional food because of its antioxidant/anti-inflammatory properties. The aim of the present study was to analyze the effect of açai pulp supplementation on cardiac remodeling after myocardial infarction in rats. After 7 days of surgery, male Wistar rats were assigned to six groups: sham animals fed standard chow (SA0, n = 14), fed standard chow with 2% açai pulp (SA2, n = 12) and fed standard chow with 5% açai pulp (SA5, n = 14), infarcted animals fed standard chow (IA0, n = 12), fed standard chow with 2% açai pulp (IA2, n = 12), and fed standard chow with 5% açai pulp (IA5, n = 12). After 3 months of supplementation, echocardiography and euthanasia were performed. Açai pulp supplementation, after myocardial infarction, improved energy metabolism, attenuated oxidative stress (lower concentration of malondialdehyde, P = 0.023; dose-dependent effect), modulated the inflammatory process (lower concentration of interleukin-10, P<0.001; dose-dependent effect) and decreased the deposit of collagen (lower percentage of interstitial collagen fraction, P<0.001; dose-dependent effect). In conclusion, açai pulp supplementation attenuated cardiac remodeling after myocardial infarction in rats. Also, different doses of açai pulp supplementation have dose-dependent effects on cardiac remodeling.

Abstract (sommario):
Previous studies in healthy rats have demonstrated a deleterious bone impact of β-agonist treatment. The purpose of this study was to examine the trabecular and cortical effects of β2-agonists at doping dose on treadmill exercising rats with estrogen deficiency. Adult female rats were ovariectomized (OVX; n = 44) or sham operated ( n = 12). Then, OVX rats received a subcutaneous injection of salbutamol (SAB) or vehicle with (EXE) or without treadmill exercise for 10 wk. Bone mineral density (BMD) was analyzed by densitometry. Microcomputed tomography and histomorphometric analysis were performed to study trabecular bone structure and bone cell activities. After 10 wk, SAB rats presented a much more marked decrease of BMD and trabecular parameters. Exercise did not change the high level of bone resorption in OVX EXE SAB compared with OVX SAB group (both on COOH-terminal collagen cross-links and osteoclast number). These results confirm the deleterious effect of β2-agonists on bone quantity (femoral BMD gain: OVX EXE, +6.8%, vs. OVX EXE SAB, −1.8%; P < 0.01) and quality (−8.0% of femoral trabecular thickness in OVX EXE SAB vs. OVX EXE), indicating that SAB suppresses the effect of EXE in OVX rats. Furthermore, we notice that the slight beneficial effect of exercise was mainly localized in the tibia. These findings indicate the presence of a bone alteration threshold below which there is no more alteration in structural bone quantity and quality. The negative effects of SAB on bone observed in this study in trained rats may indicate potential complications in doping female athletes with exercise-induced amenorrhea.

Abstract (sommario):
Inflammatory dysfunction and angiogenesis inhibition are two main factors leading to the delayed healing of diabetic wounds. Hydrogels with anti-inflammatory and angiogenesis-promoting effects have been considered as promising wound care materials. Herein, a salvianolic acid B (SAB)-loaded hyaluronic acid (HA) self-healing hydrogel (HA/SAB) with anti-inflammatory and pro-angiogenesis capacities for diabetic wound healing is reported. The HA hydrogel was prepared via the covalent cross-linking of aldehyde groups in oxidized HA (OHA) and hydrazide groups in adipic dihydrazide (ADH)-modified HA (HA-ADH) with the formation of reversible acylhydrazone bonds. The obtained HA hydrogel exhibited multiple favorable properties such as porous structures, excellent self-healing properties, a sustainable release capacity of SAB, as well as excellent cytocompatibility. In addition, the effects of the SAB-loaded HA self-healing hydrogel were investigated via a full-thickness skin defect model using diabetic rats. The HA/SAB hydrogel showed enhanced skin regeneration effects with accelerated wound closure, shorter remaining dermal space length, thicker granulation tissue formation, and more collagen deposition. Furthermore, reduced inflammatory response and enhanced vascularization were found with HA/SAB2.5 hydrogel-treated wounds, indicating that the hydrogel promotes diabetic wound healing through the promotion of anti-inflammation and angiogenesis. Our results suggest that the fabricated SAB-loaded HA self-healing hydrogel is promising as a wound dressing for the treatment of diabetic wounds.

Abstract (sommario):
Clostridium histolyticumcollagenases ColG and ColH are segmental enzymes that are thought to be activated by Ca2+-triggered domain reorientation to cause extensive tissue destruction. The collagenases consist of a collagenase module (s1), a variable number of polycystic kidney disease-like (PKD-like) domains (s2a and s2b in ColH and s2 in ColG) and a variable number of collagen-binding domains (s3 in ColH and s3a and s3b in ColG). The X-ray crystal structures of Ca2+-bound holo s2b (1.4 Å resolution,R= 15.0%,Rfree= 19.1%) and holo s2a (1.9 Å resolution,R= 16.3%,Rfree= 20.7%), as well as of Ca2+-free apo s2a (1.8 Å resolution,R= 20.7%,Rfree= 27.2%) and two new forms of N-terminally truncated apo s2 (1.4 Å resolution,R= 16.9%,Rfree= 21.2%; 1.6 Å resolution,R= 16.2%,Rfree= 19.2%), are reported. The structurally similar PKD-like domains resemble the V-set Ig fold. In addition to a conserved β-bulge, the PKD-like domains feature a second bulge that also changes the allegiance of the subsequent β-strand. This β-bulge and the genesis of a Ca2+pocket in the archaeal PKD-like domain suggest a close kinship between bacterial and archaeal PKD-like domains. Different surface properties and indications of different dynamics suggest unique roles for the PKD-like domains in ColG and in ColH. Surface aromatic residues found on ColH s2a-s2b, but not on ColG s2, may provide the weak interaction in the biphasic collagen-binding mode previously found in s2b-s3.B-factor analyses suggest that in the presence of Ca2+the midsection of s2 becomes more flexible but the midsections of s2a and s2b stay rigid. The different surface properties and dynamics of the domains suggest that the PKD-like domains of M9B bacterial collagenase can be grouped into either a ColG subset or a ColH subset. The conserved properties of PKD-like domains in ColG and in ColH include Ca2+binding. Conserved residues not only interact with Ca2+, but also position the Ca2+-interacting water molecule. Ca2+aligns the N-terminal linker approximately parallel to the major axis of the domain. Ca2+binding also increases stability against heat and guanidine hydrochloride, and may improve the longevity in the extracellular matrix. The results of this study will further assist in developing collagen-targeting vehicles for various signal molecules.

Abstract (sommario):
Background: The type of surgery performed on the spine encompasses operations for trauma, deformity, and myelopathy. The complexity of procedures is continuing to increase and older patients with significant co-morbidities are being offered ever more major procedures for which they would have previously not been considered. Developing areas include surgery for degenerative scoliosis and an increase in operations performed on the anterior lumbar spine Spinal anaesthesia for Lumbar Interverterbral Disc Prolapse (PLID) surgery is becoming increasingly more popular because this anaesthetic technique allows the patient to comfortable self-position and avoid neurological injury that may occur with prone positioning under general anaesthesia. PLID surgery is also a comparatively cost effective surgical procedure. Aim of the study: The aim of the study was to observe the extent of surgical options as per pathological outcome in terms of postoperative pain, immediate functional recovery and patient’s satisfaction for undergoing PLID surgery under spinal anaesthesia. Methods: This observation study was conducted in the department of Neuro surgery Sylhet MAG Osmani Medical College Hospital in association with Central Hospital Limited Sylhet from January 2007 to July 2019. A total of 4000 healthy cooperative patients with ASA I-III grading, undergoing Lumbar Interverterbral Disc Prolapse (PLID) surgery at single level to two levels also recurrent cases operative maximum twice previously were selected as study population. A comprehensive perioperative was carried out documenting per operative events anaesthetic complications, pace of physiological and functional recovery and patient’s satisfaction. Variables were recorded as pain level using a visual analogue scale (VAS) at 1, 6, 12 & 24 hours; patients level of satisfaction during the stay on the ward using verbal rating scale (VER); during of surgery; per amount of blood loss. Data were analyzed by SPSS version 19.0. Results: Among 4000 participants, man was 2416(60.4%) and female 1684 (39.6%). In incidence of PLID surgery 36-45 years age group was almost fifty percent 49.42%. In level of PLID L3/4 was highest 39.0%. Regarding of per operative blood, new was 3337(84.18%) & mean value was 47.65(±9.14) and recurrent 633(15.82%) & mean value was 55.60(±13.80). In duration of surgery the mean of new was 22.51(±3.67)& recurrent 26.72(±5.78). Regarding per operative complications, hypertension was highest 1440(36.0%) followed by hypotension 992(24.4%) & nausea/vomiting 960(24.0%).Average hospital stay was 36 to 48 hours. Conclusion:As our results correspond to the others available studies it is clear that, spinal anaethesia can be definitely used for doing at least 2 levels of PLID surgery as it is also more cost effective and patient need to stay minimum in time duration.

Abstract (sommario):
This study was conducted in the lath house of the Department of Horticulture and Landscape Design/ College of Agriculture/ Tikrit University during the growing season of 2017 to investigate the effect of magnesium application and the foliar spraying of both gibberellic and salicylic acids on the vegetative growth characteristics of peach saplings CV. Miski, aged one year which were grafted on Apricot seedlings. Magnesium was added in three concentrations (0, 50 and 100 mg.litre-1) and was labelled as Mg0, Mg1 and Mg2 consecutively. The gibberellic acid was sprayed in three concentrations (0, 50 and 100 mg.liter-1) and labelled as GA0,GA1 and GA2 consecutively. Besides the salicylic acid was sprayed with the following concentrations (0, 100 and 200 mg.L-1) and labelled as SA0, SA1 and SA2 consecutively. All these processes were performed starting from April 10 three times, with a time interval of three weeks. The experiment was performed based on the split-plot system in Randomized Complete Block Design (RCBD) in which the various magnesium concentrations were added to the main plots and both the gibberellic and salicylic acids were applied to the subplots. The results showed that the addition of magnesium has positively increased the main stem diameter, single leaf area, total leaves area per plant and the relative chlorophyll concentrations in leaves. The height and the diameter of a sapling, length of the branches, leaf area and total leaves area of sapling were increased as a result of foliar spraying with gibberellic acid. The spraying of salicylic acid has a positive effect on the saplings’ characteristics (leaf area, total leaves area and relative chlorophyll concentration in leaves). The dual or triple interaction treatments between the three studied factors had the positive results in most characteristics were investigated.

Abstract Objective This study aimed to evaluate sleep behaviors among college students, to assess salivary alpha-amylase (sAA) and heart rate variability (HRV) in association with stress, and to investigate sleep-related factors including sAA, HRV, and stress among them. Methods Saliva samples for sAA assessment and HRV measurements in the supine position were taken between 3 PM and 6 PM. The level of prolonged psychological stress for the previous week was evaluated using the Korean version of the Global Assessment of Recent Stress (GARS-K), and sleep behaviors were assessed using an actigraphy device. Results A total of 86 healthy college students participated in this study. Sleep behaviors of the college students were not good, with 84% sleep efficiency (SE) and 62.7 min wake after sleep onset (WASO). The average sAA level was 65.8 U/mL in the participants. Although neither the sAA level nor HRV indices were significantly correlated with prolonged psychological stress, decreased normalized high frequency (nHF) on HRV was independently associated with a higher level of stress when adjusted for age and sex. Higher stress (r = −0.276, P = 0.011) and lower sAA (r = 0.266, P = 0.030) had significant correlations with shorter time in bed; however, it was sAA that was independently associated with time in bed (β = 0.244, p = 0.044). Decreased nHF (β = 0.245, P = 0.027) and higher body mass index (BMI) (β = −0.224, P = 0.043) were independently related to and poorer SE. Conclusions Poor sleep behaviors were associated with decreased parasympathetic activity, a physiological change to psychological stress, rather than with psychological stress itself among college students. Thus, sAA and HRV should be considered as significant factors for impaired sleep behaviors in relation to psychological stress.

Abstract (sommario):
Les travaux de thèse présentés dans ce manuscrit sont consacrés à l'étude du collage SAB (de l'anglais « Surface Active Bonding ») appliqué à la fabrication d'hétérostructures. Il s’agit d’assemblages de plusieurs matériaux souvent utilisés dans l'optoélectronique et la photonique. Le collage SAB est une technique de collage direct sous ultravide permettant l'adhésion spontanée de deux surfaces sans l’utilisation de colle.Jusqu’à présent, les contraintes mécaniques, résultant des différences de coefficients de dilatation thermique entre les matériaux formant l’hétérostructure, représentent un défi majeur pour la fabrication d’hétérostructures ; mais contrôlées, elles peuvent également être avantageuses pour la fabrication et la qualité des produits finaux.L’approche technologique utilisée dans cette étude se concentre sur la fabrication d'hétérostructures en films minces monocristallins à partir de substrats épais, en utilisant le procédé Smart Cut™ et le collage SAB.Ce travail introduit pour la première fois la possibilité de réaliser des collages à chaud grâce à la technologie de collage SAB, en développant une nouvelle méthode appelée SAHB pour « Surface Active Hot Bonding ». Cette dernière offre la possibilité de contrôler la température lors de l’assemblage, permettant ainsi de gérer les contraintes mécaniques dues aux différences de coefficients d'expansion thermique dans l’hétérostructure. Une application remarquable de cette nouvelle méthode SAHB, mise en oeuvre dans le cadre de ces travaux, est la réalisation de reports de films contraints de germanium monocristallins de plusieurs centaines de nanomètres sur substrats de silicium. La modélisation par éléments finis est utilisée pour comprendre cette technologie de collage SAHB, car elle permet de visualiser les déformations des structures et d'estimer les niveaux de contrainte afin de limiter la casse de l’hétérostructure lors de sa fabrication, tout en maximisant la contrainte stockée dans le film reporté. De plus, l’étude du collage SAHB permet de mettre en évidence la nécessité d’une gestion précise de la température et d’une grande qualité de l'atmosphère de collage pour garantir son efficacité.Cette étude a mené à l’investigation des mécanismes du collage SAB, par des travaux sur l’impact de l’activation sur l’amorphisation l’interface de collage. Les résultats montrent que la seule présence de liaisons pendantes ne suffit pas à expliquer la très forte adhérence des collages SAB standards, mais qu’il est nécessaire que la surface soit suffisamment « malléable » pour permettre aux pointes d'aspérités de s'écraser et aux liaisons pendantes de s'appairer.Les travaux présentés dans ce manuscrit introduisent une nouvelle méthode de collage, le SAHB, et développent la fabrication des premières hétérostructures par cette voie. Cette méthode ouvre de nouvelles perspectives pour la fabrication de structures complexes et la manipulation des contraintes dans les matériaux hétérogènes.Mots clés : Collage direct, collage covalent, collage SAB, collage d’hétérostructures, collage de silicium, collage SAHB, transfert de film, films minces monocristallins
These research work presented in this thesis are dedicated to the study of SAB, "Surface Active Bonding", for the fabrication of heterostructures. These are assemblies of several materials often used in optoelectronics and photonics. SAB bonding is a direct bonding technique under ultrahigh vacuum that enables the spontaneous covalent bonding of two surfaces without glue.To date, mechanical stresses, resulting from differences in thermal expansion coefficients between the materials forming the heterostructure, represent a major challenge for the manufacture of heterostructures; but controlled, they can also be advantageous for the manufacture process and the quality of the final products.The field of studies developed in this study focuses on the fabrication of single-crystal thin-film heterostructures from thick substrates, using the Smart Cut™ process and SAB bonding.This work introduces for the first time the possibility of producing hot bonds using SAB bonding technology, by developing a new method called SAHB for "Surface Active Hot Bonding". The latter offers the opportunity of controlling the temperature during bonding, enabling mechanical stresses due to differences in thermal expansion coefficients in the heterostructure to be managed. One of the main applications of this new SAHB method is that it can be used to transfer strained single-crystal germanium films of several hundred nanometers onto silicon substrates. Finite-element modeling is used to understand this SAHB bonding technology, as it enables structural deformations to be visualized and stress levels to be estimated in order to limit heterostructure breakage during fabrication, while maximizing the stress stored in the transferred film. In addition, the study of SAHB bonding highlights the need for precise temperature management and a high-quality bonding atmosphere to guarantee its effectiveness.This study led to the investigation of SAB bonding mechanisms, with work on the impact of activation on the amorphization of the bonding interface. The results show that the mere presence of dangling bonds is not sufficient to explain the very high adherence of standard SAB, but that it is necessary for the surface to be sufficiently "malleable" to allow asperity tips to crush and dangling bonds to pair.The work presented in this manuscript introduce a new bonding method, the SAHB, and develops the production of the first heterostructures by this route. This method opens up new perspectives for the fabrication of complex structures and the manipulation of stresses in heterogeneous materials.Keywords: Direct bonding, covalent bonding, SAB bonding, heterostructure bonding, silicon bonding, SAHB bonding, film transfer, thin monocrystalline films

Abstract (sommario):
This research study addresses the problem of unmet facilities needs in the California Community College (CCC) system with a case study analysis of two major campus construction projects within the City College of San Francisco system (CCSF). Specifically, this study is intended to provide insight into the difficulties facing CCC administrators regarding unmet facilities needs within their campuses, and the overall processes and challenges involved in constructing the 21 st century CCC campus. Interviews with the campus deans of the CCSF Chinatown/North Beach and Mission District Campuses revealed that challenges for construction and modernization projects in the San Francisco City College system derive more from external stakeholder concerns than internal governance systems. In particular, the study focused on a satellite campus dean's role in the shared governance system for CCSF construction projects and how they effectively work in conjunction with CCSF leadership to garner community support, while mediating external opposition for projects. Findings from the study concurred in part with current literature regarding construction delays related to external stakeholder opposition and the role college administrators must play in ameliorating environmental, historical preservation, and corporate interest concerns for projects. Specifically, campus deans in the San Francisco City College system found that the practices of conducting information hearing sessions and forming internal/external/community advisory committees facilitated productive forums for hearing the concerns of key campus personnel and community stakeholders. Additionally, these practices allowed for more efficient project execution and the promotion of improved community relations within the neighboring communities for the campus projects in this study.

Abstract (sommario):

The college admission systems of the United States require the Scholastic Aptitude Test (SAT) and American College Testing (ACT) examinations. Although, some resources suggest that SAT and ACT scores give some meaningful information about academic success, others disagree. The objective of this study was to determine whether there is significant predictive validity of SAT and ACT exams for college success. This study examined the effectiveness of SAT and ACT scores for predicting college students’ first year GPA scores with a meta-analytic approach. Most of the studies were retrieved from Academic Search Complete and ERIC databases, published between 1990 and 2016. In total, 60 effect sizes were obtained from 48 studies. The average correlation between test score and college GPA was 0.36 (95% confidence interval: .32, .39) using a random effects model. There was a significant positive relationship between exam score and college success. Moderators examined were publication status and exam type with no effect found for publication status. A significant effect of exam type was found, with a slightly higher average correlation for SAT compared to ACT score and college GPA. No publication bias was found in the study.

Abstract (sommario):
A great many Catholic colleges existed in the United States at the opening of the twentieth century. Exactly how many it is impossible to say with certainty because any answer presupposes agreement on the answer to a prior question: “What should be counted as a college?” The Catholic Directory for 1900 listed 10 universities, 178 “colleges for boys,” 109 seminaries, and 662 “academies for girls.” According to this count, there were no Catholic women’s colleges at that time, although the College of Notre Dame of Maryland graduated its first baccalaureate class in 1899 and is included among the 128 colleges for women listed in U.S. Commissioner of Education’s Report for 1899-1900. The same Report, however, listed only 62 Catholic institutions among the 480 included under the heading: “Universities and colleges for men and for both sexes.” No doubt some Catholic colleges simply failed to provide the information necessary to appear in the Commissioner’s Report. But their failure to do so is in itself significant; and even assuming that is what happened, it still leaves an enormous gap between the Commissioner’s figures and the 188 colleges and universities reported in the Catholic Directory. Moreover, many of the “colleges for boys” could, with equal justice, have been called academies, since elementary- and secondary-level students made up the majority of their student bodies. As the case of Notre Dame of Maryland indicates, Catholic “academies for girls” were beginning to upgrade themselves to collegiate status. Had the word college been more freely applied to non-Catholic institutions for women at an earlier date, a good many of these academies would probably have called themselves colleges long before, for they did not differ all that much from the “colleges for boys” in terms of curricular offerings and age-range of students. While the situation of Catholic institutions was particularly murky, the question “What makes a college a college?” engaged the attention of practically everyone involved in secondary and collegiate education at the turn of the century.

Abstract (sommario):
Abstract Rather than warfare, the typical motif in the transition from the old-time colleges to the new universities was peaceful revolution. Few of the old guard were willing to take a stand, as Porter did, that would risk looking sectarian. On the other side, most of the revolutionaries were sons of the evangelical college tradition and wished to emphasize that they were the true heirs to its ideals. While they were well aware of a need for a break from the past, they also saw continuity between the old colleges and the new universities. Nowhere were such continuities suggested in a more intriguing way than in the origins of the University of California out of the College of California. On October 9, 1867, the trustees of the College of California, a private college, voted to cede all its assets to the proposed new state university. The College of California, which had opened its doors in Oakland in 1860, was a typically New England enterprise, conducted by New School Presbyterians and Congregationalists, aspiring to establish the “Yale of the West.” Although the college was struggling and had few students, it was not entirely impoverished. Its most valuable tangible asset, which it donated to the state, was a magnificent tract of land in a nearby area that the college leaders had named Berkeley.

Abstract (sommario):
Abstract Chapter six shows that, rather than fostering a narrow nationalism, the racial exclusions embedded in the Master Plan inspired a wave of multiracial activism on campuses across California. At the UC, CSU, and community college levels, student activists worked together, forming alliances and rainbow coalitions to increase the recruitment and matriculation of diverse working-class youth. This activism was directed, quite consciously, at the exclusionary admissions standards enacted by the Master Plan in 1960. The chapter succinctly explores the Third World Liberation Front (TWLF) at San Francisco State College, which carried out a five month long strike for affirmative action and ethnic studies. The successful strike at SF State established a model for other campus struggles throughout California, including the Third World Strike at UC Berkeley, the Lumumba-Zapata coalition at UC San Diego, and interracial alliances organized at various community colleges.

Abstract (sommario):
Projects described in this chapter are aimed at enhancing our thinking with pictures. “Thinking with Pictures” encourages the reader to use visual thinking as an instrument of acquiring knowledge, and introduces two projects aimed at developing visual literacy and applying various ways of visual expression. “Collage” introduces collage technique as a tool for visual communication. Two projects provided in this chapter are aimed at enhancing visual literacy and skills. “Sketching a shoe” is intended to amplify one’s confidence about one’s ability to depict things, and build a feeling of being prepared to make quick drawings on a board or on iPad. This project will encourage the reader to make sketches that strengthen one’s own argumentation, show what one wants to be seen, and help to convey one’s own solution in a visual way. “Creating a Composition with a Crowd” encourages the reader to draw a group of people and apply visual reasoning by showing background scenery that has an explanatory power. The next part of the chapter tells about collage because one may say without exaggeration that in the digital times most artists apply the form of a collage in their work. The Internet is flooded with ready images, clipart, art, and design samples, intriguing specimens. More importantly, ideas are not copyrighted. Before the advent of computers many artists applied techniques of cutting and pasting readymade material, thus making collages (two dimensional) and assemblages (three dimensional) of different forms.

Abstract (sommario):
Post-traditional students appear to be the highest growing population of students on American college campuses. About 1/3 of the people, who are working and learning, are over the age of 30, which is a very substantial increase over what we saw in the 1980s and 1990s. Carnevale (2015). However, data suggests male students do not persist at the same level as their female counter parts in higher education. The enrollment in colleges has been favoring females since the 1970’s (Borzelleca, 2012). Given this increase in post-traditional students this paper will examine the experience of post-traditional male students as they attempt college level learning. This research paper investigates what supports and services are necessary for male post-traditional students to attain success. During the fall of 2022 a comprehensive qualitative research study was conducted involving 8 post-traional male students at a community college in an suburban New York location..

Abstract (sommario):
The U.S. Department of Labor awarded a $2.3 million grant to the University of Missouri-Columbia (MU) in 2006 in response to the need for well-trained Radiation Protection Technicians (RPTs). The RPT curriculum initiative resulted from significant collaborations facilitated by MU with community colleges, nuclear power plants, professional organizations, and other nuclear industry stakeholders. The objective of the DOL project is to help increase the pool of well-qualified RPTs to enter the nuclear workforce. Our work is designed to address the nuclear industry’s well-documented, increasingly significant need for RPTs. In response to this need, MU and AmerenUE’s Callaway Nuclear Power Plant first partnered with Linn State Technical College’s Advanced Technology Center (LSTC/ATC) to initiate a two-year RPT degree program. The success of this program (enrollments have been increasing over the past four years to a Fall 2007 enrollment of 23) enabled the successful proposal to the DOL to expand this program nationwide. DOL participants include the following partners: Linn State Technical College with AmerenUE – Callaway; Central Virginia Community College with AREVA; Estrella Mountain Community College with Arizona Public Service – Palo Verde; MiraCosta Community College with Southern California Edison – San Onofre; and Hill College with Texas Utilities – Comanche Peak. The new DOL grant has allowed redevelopment of the LSTC/ATC curriculum using a web-based, scenario driven format, benchmarked against industry training standards. This curriculum will be disseminated to all partners. Integral in this curriculum is a paid, three to four month internship at a nuclear facility. Two of the six new RPT courses have been developed as of the end of 2007. Four of five partner schools are accepting students into this new program starting in the winter 2008 term. We expect that these institutions will graduate 100 new RPTs per year to help alleviate the personnel shortage in this critical area of need.

Abstract (sommario):
Alcohol and cannabis are commonly used by U.S. college students and often used simultaneously (simultaneous alcohol and marijuana [SAM] use). Better understanding situations in which SAM use is planned or unplanned and related consequences of these distinct SAM use events will inform prevention and intervention efforts. We extended previous daily-level research by examining motives and contexts (social, physical) as indicators of unplanned vs. planned SAM use occasions, as well as by parsing specific plans for alcohol use and for cannabis use on SAM use occasions. Specifically, we examined: unplanned alcohol and marijuana (UAM) use, planned mono-substance (either alcohol or cannabis but not both) use (MSU), and planned SAM use. College student SAM users (N=341; 53% women) were recruited from three U.S. universities and completed 56 days of data collection with five repeated surveys each day. Most SAM use occasions were planned (73% of occasions), followed by planned MSU (18%), and by UAM use (10%). Two-level generalized linear mixed-effects models were conducted to account for nesting of occasions within persons and the three-category nominal outcome. All models included age, sex, recruitment site (school), weekend, and other drug use as covariates. At the within-person level, using for social or enhancement reasons was related to higher odds of planned SAM use (vs. UAM use). These reasons for use were also related to planned SAM use when compared to planned MSU, whereas using because it was offered or to cope was related to lower odds of planned SAM use (vs. planned MSU). Using at home or alone was linked to lower odds of planned SAM use (vs. UAM use), and using at a party, friend’s place, with friends, with more intoxicated people, and with more people using cannabis was associated with higher odds of planned SAM use. An identical pattern was found when comparing planned SAM use to planned MSU. When disaggregating “planned MSU” into planned alcohol use-unplanned cannabis use vs. planned cannabis use-unplanned alcohol use, using for social or enhancement reasons was related to higher odds of planned alcohol-only use. Likewise, using at a party, with friends, with strangers/acquaintances, with more intoxicated people, and with more people using cannabis were related to higher odds of planned alcohol-only use. Using at home or alone was linked to lower odds of planned alcohol-only use. Findings suggest that interventions should target days when college students are planning for SAM use. Mobile health interventions could also focus on higher risk motives (e.g., social) and contexts (e.g., party) that were indicators of planned SAM use, as well as target individuals who endorse using substances to cope or because substances were offered, with these latter individuals being at risk for unplanned SAM use when only MSU was originally planned. Specifically, ecological momentary interventions and just-in-time adaptive interventions could send protective behavioral strategies to individuals endorsing intentions for use and high-risk motives or contexts to reduce the heavy alcohol and cannabis consumption that was associated with planned SAM use.

Abstract (sommario):
Human brain is suspended in the skull through three fibrous tissue layers, dura mater, arachnoid and pia mater, known as the meninges layer. The space between the arachnoid and pia mater is known as subarachnoid space (SAS). SAS consists of arachnoid trabeculae and cerebrospinal fluid (CSF), which stabilizes the shape and the position of the brain during head movements. Through solid-fluid interaction, it has been shown that subarachnoid space (SAS) trabeculae plays an important role in damping and reducing the relative movement of the brain with respect to the skull, thereby reducing traumatic brain injuries (TBI), (Zoghi and Sadegh 2010). While the functionality of the SAS is understood, the architecture, the histology and biomechanics of this important region has not been fully investigated. In their modeling of the head, previous investigators have over simplified this important region. This is due to the trabeculae’s complex geometry, abundance of trabeculae and lack of the material properties. These simplifications could lead to inaccurate results of finite element head studies. Killer HE, et al, (2003) investigated the trabecular histology of optical nerves and Alcoldo, et al (1986) used Scanning Electron Microscopy (SEM) to study the arachnid mater of the SAS. The result of these studies reveal that the arachnoid is a thin vascular layer composed of fibroblast cells interspersed with bundles of collagen and the trabecula is also a collagen based structure. However, the brain SAS trabecular architecture and histology has not been fully investigated. The goal of this study is to investigate the mechanotransduction of the head impacts to the brain with the emphasis on the role of material modeling and architecture of the subarachnoid space as it relates to Traumatic Brain Injuries (TBI). This goal was accomplished through three aims including experimental studies, material modeling and a 3D finite element model. In this paper, to present a global view of this investigation, brief descriptions of each aim are presented. It was concluded that the trabeculae contain collagen Type I with tree-shaped architecture and the validated material properties of SAS is approximately E = 1000 Pa.

Abstract (sommario):
Blunt head impacts cause relative motion between the brain and skull. This increases the normal and shear stresses in the (skull/brain) interface region, which leads to the rupture of cerebral blood vessels and in particular bridging veins. Mechanical properties of meningeal layers, in particular, subarachnoid space (SAS) trabeculae and the pia mater are not well established in the literature and could have a wide range depending on an individual. In our previous studies, knowing that SAS trabeculae and pia mater are collagen-based structures, these mechanical properties have been estimated using the properties of similar collagen based tissues. However, recent study Xin Jin et al. (2008), suggests that the mechanical properties of trabeculae and the pia matter are significantly less than a collagen-based tissue. Therefore, the goal of this study is to investigate the effect of the mechanical properties of these tissue on the stress and strain of the neighboring tissues when the head is subjected to a blunt impact. Specifically, the objectives of this study is to determine the stress/strain changes of the cerebral blood vessels as a function of the mechanical properties of the SAS trabeculae and pia mater, when the loading and the boundary conditions of the local model are kept the same. Note that the variation of the properties of these tissues affects the failure of cerebral blood vessels which leads to traumatic brain injury.

In 2022 Annual Scientific Meeting of the Research Society on Marijuana. Research Society on Marijuana, 2022. http://dx.doi.org/10.26828/cannabis.2022.02.000.09.

Abstract (sommario):
Substance use motives are strong predictors of alcohol and cannabis use and consequences among college students. Both simultaneous alcohol and cannabis (i.e., marijuana; SAM) and concurrent alcohol and cannabis (i.e., marijuana; CAM) use are associated with higher endorsement of certain types of motives compared to single drug-only use, which may explain heightened risks for experiencing negative consequences evidenced by co-users. Understanding whether motives differ according to type of use could provide an important avenue for intervention efforts; however, research has not yet examined if motives differ between SAM and CAM users. Thus, the purpose of this study was to examine how SAM, CAM, and single drug-only users differ on alcohol and cannabis motives. Participants were 2295 college students (72.4% female, 50.6% white) from seven US universities who reported past-month alcohol and/or cannabis use (41.2% SAM, 12.4% CAM, 39.1% alcohol-only, 7.3% cannabis-only). Participants completed measures of alcohol and cannabis motives and past-month substance use frequency via online survey. Two multivariate analyses of covariance (MANCOVA) models were conducted to examine differences on cannabis motives (i.e., enjoyment, celebration, conformity, and coping) and alcohol motives (i.e., social, coping, enhancement, and conformity) separately by past-month user status, controlling for sex and frequency of use. The overall cannabis model was significant, with between-group effects on conformity (F(2,1398)=3.90, p=.02), coping (F(2,1398)=6.96, p=.005), and celebration (F(2,1398)=5.83, p=.015) motives. Pairwise comparisons utilizing a Bonferonni-corrected alpha (p<.017) indicated that SAM users endorsed greater coping (p=.002) and celebration (p=.004) motives than CAM users. Moreover, cannabis-only users held greater coping motives than CAM users (p=.009). SAM and cannabis-only users did not differ on any motives. The overall alcohol model was also significant, with between-group effects on all four alcohol motives. Pairwise comparisons indicated that SAM users endorsed greater social (p=.012), coping (p=.003), and enhancement (p<.001) motives than CAM users. Moreover, SAM users were higher on all four motives (all ps<.01) than alcohol-only users, and CAM users were higher on social motives (p=.013) than alcohol-only users. Results indicate that SAM and CAM users can be importantly differentiated by alcohol and cannabis motives, with SAM users reporting greater motives for use related to coping with negative mood and enhancing positive mood/celebrating for both substances. Interestingly, SAM users did not differ from single drug-only users on cannabis motives, though they uniformly reported greater alcohol motives. Given that SAM users reported stronger enhancement and coping motives than CAM users across both drugs, it is possible that college students may opt to combine their substances when they are predominantly motivated to use for mood-related reasons. Considering that SAM users only differed from single-drug users with regard to alcohol, but not cannabis motives, it may be that simultaneous use particularly enhances alcohol-related desirable outcomes, though not necessarily desirable cannabis outcomes. As such, intervention efforts designed to reduce SAM use may benefit from specifically targeting alcohol and mood-related motives. Moreover, research is needed to examine the within-person effects that motives may have on type of use.

Testo completo
Abstract (sommario):
In his essay “Architecture Enters the Age of Post-Digital Drawing”, Sam Jacob advocates for a new method of representation that eschews the digital technology used to create photo-realistic renderings in favor of an approach that utilizes digital collage in order to embrace drawing as a work of fiction. While his criticism of photo-realism is valid, it is also arguable that a post-digital age in architecture should more heavily concerned with reality. An alternative method of representation is investigated that utilizes photographs of physical models that are digitally modified in order to emphasize the experiential qualities of architecture. Whereas Sam Jacob uses the zombie as a metaphor for a collage technique risen from the dead, the cyborg may be a more apt analogy for a post-digital method of representation that is focused on real world, but also open to embracing the potential of digital enhancements. The paper explores the role of physical models, photography, and in some cases digital technology as a means to generate perspectival views by architects of the past and the present with the hope that these precedents can be utilized to inform an alternate post-digital era to the one Sam Jacob advocates. These techniques have been applied in a series of design studios focused on shifting the focus from external form and abstraction toward internal experience with an emphasis on reality. While this approach diverges from what students’ expectations are for design, many have embraced the process and stated that the studio has helped to shape their view of the realm of architecture.

This significantly impacts students and Universities alike financially and in wasted efforts. Previous research shows that there are early indicators of college success in the high school record such as grades, attendance, disciplinary incidents, and ACT/SAT scores. Additionally, there are factors in college experiences, especially in the first year of college which impact the likelihood of dropout. However, to the best of our knowledge, there is no comprehensive model that can accurately predict the likelihood of college dropout and provide an early warning either in high school and/or the first year of college. We were fortunate to get access to longitudinal ten-year data of high school graduates of public schools in a county in the United States and were able to follow a subset of students who went to a specific public University. Based on more than one hundred variables from high school and college records and students’ final status we trained various machine learning models to predict the likelihood of student dropout and identify factors that play a significant role. Based on this information a prototype decision support system was developed and evaluated.

Abstract (sommario):
This research brief uses nationally representative data from the 2012/17 Beginning Postsecondary Students Longitudinal Study (BPS:12/17) to examine post-college transitions of US undergraduates into the skilled technical workforce (STW), defined here as workers in a collection of occupations that require significant levels of science, technology, engineering, and mathematics (STEM) knowledge but not necessarily a bachelor’s degree for entry. Thus far, empirical research on the STW has been limited by a dearth of data; however, based on newly available data from BPS:12/17, the findings in this report indicate that STW employment provides workers with above-median salaries, more equitable wages, a variety of benefits, and clear career paths. STW jobs attract diverse populations, especially those from underrepresented groups (e.g., Hispanics, individuals from low-income backgrounds, and those whose parents do not have college education). US community colleges and sub-baccalaureate programs play a large role in developing the STW.

Abstract (sommario):
In the decade after the Civil Rights Act of 1964, African Americans made historic gains in accessing employment opportunities in racially integrated workplaces in U.S. business firms and government agencies. In the previous working papers in this series, we have shown that in the 1960s and 1970s, Blacks without college degrees were gaining access to the American middle class by moving into well-paid unionized jobs in capital-intensive mass production industries. At that time, major U.S. companies paid these blue-collar workers middle-class wages, offered stable employment, and provided employees with health and retirement benefits. Of particular importance to Blacks was the opening up to them of unionized semiskilled operative and skilled craft jobs, for which in a number of industries, and particularly those in the automobile and electronic manufacturing sectors, there was strong demand. In addition, by the end of the 1970s, buoyed by affirmative action and the growth of public-service employment, Blacks were experiencing upward mobility through employment in government agencies at local, state, and federal levels as well as in civil-society organizations, largely funded by government, to operate social and community development programs aimed at urban areas where Blacks lived. By the end of the 1970s, there was an emergent blue-collar Black middle class in the United States. Most of these workers had no more than high-school educations but had sufficient earnings and benefits to provide their families with economic security, including realistic expectations that their children would have the opportunity to move up the economic ladder to join the ranks of the college-educated white-collar middle class. That is what had happened for whites in the post-World War II decades, and given the momentum provided by the dominant position of the United States in global manufacturing and the nation’s equal employment opportunity legislation, there was every reason to believe that Blacks would experience intergenerational upward mobility along a similar education-and-employment career path. That did not happen. Overall, the 1980s and 1990s were decades of economic growth in the United States. For the emerging blue-collar Black middle class, however, the experience was of job loss, economic insecurity, and downward mobility. As the twentieth century ended and the twenty-first century began, moreover, it became apparent that this downward spiral was not confined to Blacks. Whites with only high-school educations also saw their blue-collar employment opportunities disappear, accompanied by lower wages, fewer benefits, and less security for those who continued to find employment in these jobs. The distress experienced by white Americans with the decline of the blue-collar middle class follows the downward trajectory that has adversely affected the socioeconomic positions of the much more vulnerable blue-collar Black middle class from the early 1980s. In this paper, we document when, how, and why the unmaking of the blue-collar Black middle class occurred and intergenerational upward mobility of Blacks to the college-educated middle class was stifled. We focus on blue-collar layoffs and manufacturing-plant closings in an important sector for Black employment, the automobile industry from the early 1980s. We then document the adverse impact on Blacks that has occurred in government-sector employment in a financialized economy in which the dominant ideology is that concentration of income among the richest households promotes productive investment, with government spending only impeding that objective. Reduction of taxes primarily on the wealthy and the corporate sector, the ascendancy of political and economic beliefs that celebrate the efficiency and dynamism of “free market” business enterprise, and the denigration of the idea that government can solve social problems all combined to shrink government budgets, diminish regulatory enforcement, and scuttle initiatives that previously provided greater opportunity for African Americans in the government and civil-society sectors.

Abstract (sommario):
The Data Science Technician Education Program (DataTEC) at Florida State College at Jacksonville (FSCJ) addresses the growing demand for Data Science skills training at the Associate's degree and technical certificate levels. As the first program in Florida to offer a Data Science technical certificate, DataTEC enables students to earn up to six industry-recognized certifications and two college credit certifications while pursuing their Associate's degree. From 2021-2023, 104 students, representing a diverse population of 45% women and 27% students of color, participated in six courses (Excel, Python, SAS, Java, and R) and completed self-efficacy surveys. Results indicated small but positive increases in students’ self-efficacy, particularly in Python and Excel courses. Notably, 67% of students expressed a desire to pursue careers in industry, with most students employed either full-time or part-time. Additionally, from 2021-2024, five faculty members participated in DataTEC’s Working Connections sessions, which provided professional development on topics such as SAS and R programming. These sessions, attended by 74 participants from 29 institutions across 19 states, included a focus on addressing unconscious bias and stereotype threat in teaching. A pre-and post-survey analysis demonstrated a significant improvement in faculty members' ability to identify unconscious bias and stereotype threat in Data Science education, highlighting the program’s broader impact on fostering more inclusive learning environments.

Abstract (sommario):
The collapse of Silicon Valley Bank (SVB) and Signature Bank on 8-10 March 2023 has triggered deep financial turmoil in the US and prompted financial and monetary authorities to intervene to swiftly avert a contagion. SVB specialized in providing finance and banking services to venture-backed start-ups, most of which are technology firms. It was the largest US bank to fail since the global financial crisis (GFC) of 2008. SVB’s failure is generally attributed to liquidity exacerbated by large and quick withdrawals, net interest margins associated with the broader tech sector downturn, and rising interest rates that resulted in the deterioration of their balance sheets because of large unrealized losses. The collapse of SVB occurred amid tightening global financial conditions and increasing uncertainty about global recovery prospects. As such, it is imperative to understand and examine the extent to which broader central bank policies interacted with SVB’s failure. In 2022, in response to the global inflation acceleration, central banks, especially the Federal Reserve System (the Fed) of the US, raised interest rates, from 0.125% in February 2022 (pre-East European crisis) to 4.625% in February 2023. Because of the shift from monetary easing to tightening, bond yields have started to reflect changing market sentiments in the US, the impact of which can be observed in bank balance sheets. As a result, the value of long-term assets, such as government bonds and mortgages, have deteriorated, exposing solvency concerns and liquidity stress, especially for mid-sized and regional banks. Despite massive bailouts for the US banking sector, investor sentiment has remained fragile and global contagion risks remain. This topical paper aims to provide further insights into the US banking crisis as it unfolds. The analysis focuses on the following aspects: (i) understanding the circumstances that led to the crisis (ii) highlighting the policy reactions so far, (iii) assessing the risks of contagion globally, and (iv) drawing potential lessons and recommendations.

Abstract (sommario):
This rapid evidence review collates available evidence on women’s participation in Technical and Vocational Education and Training (TVET) (focused on Middle East North Africa, Sub-Saharan Africa, and Southeast Asia regions) and impact on social and economic development. The review notes that overall, the existing literature on vocational training programs in the global south has important gaps. The limited evidence and variation of impacts found in available studies across the global south may partly be explained by differences in social, economic, and labour market conditions, existing skill levels of targeted groups, and training program characteristics. Despite these challenges positive impacts have been identified in the following areas: impact on poverty; impact on inequality and impact on social exclusion.

Testo completo
Abstract (sommario):
We investigate the assimilation of immigrant youth in Ecuador. Focusing on formal schooling and employing administrative data from high schools, we document subtle ways by which assessment biases against students with an immigrant background play a significant role in this assimilation process. We find that, after holding constant performance on blindly scored proficiency tests, teacher-assigned grades in Mathematics and Spanish are consistently lower for students from immigrant families. We show that these results are robust with respect to the omission of socio-emotional and behavioral traits that are likely valued by teachers. These differentials are larger for male students and those attending urban schools. While these grading differentials have direct impact over high school graduation rates, they may also discourage future human capital investments, potentially leading to lower college attendance, distorted choice of major, and sub-optimal labor market outcomes, which are all well know elements for the economic assimilation of immigrants.

Testo completo
Abstract (sommario):
The Taliban’s edict prohibiting poppy cultivation and the use and trade of all types of narcotics across Afghanistan has had a profound impact on the country’s rural population, particularly in regions that saw the highest volumes of poppy cultivation. The disruption to farmers’ livelihoods comes amidst a collapsing national economy that promises few viable long-term alternatives. Poppy has long been Afghanistan’s most valuable cash crop, and saw a significant expansion during the two decades of the Republic that followed the Taliban’s late 2001 ouster. Its labour-intensive cultivation employed several hundred thousand people, pushing up wages and living standards of those directly and indirectly involved. As Afghanistan faced the worst drought in decades around the time of the Taliban’s August 2021 return to power, poppy’s resilience and relatively low water needs made it all-the-more attractive. Afghanistan’s diplomatic and economic isolation after the Taliban’s August 2021 forceful seizure of power has devastated an already struggling economy. The freezing of around US$9 billion in central bank foreign reserves, held mostly in the U.S., triggered a collapse of the local currency and a major liquidity crisis, while aid cut-offs and sanctions triggered hyper-inflation and impeded trade and other business. Without tangible Taliban commitments to basic rights and equality, especially of girls and women, any deep international economic engagement remains highly unlikely. A brutal economic crisis will only magnify the poppy ban’s impact on households.
