Cross-campus collaboration and its impact on resident students at Rowan University

The purpose of this study was to explore the role of cross-campus collaboration at Rowan University and understand the impact it has on resident students. By conducting multiple semi-structured interviews, I sought to understand the view of cross-campus collaboration from professionals from both academic and student affairs. After conducting a thematic analysis on the collected data, the findings of the study illustrated that there are some instances of cross-campus collaboration happening at Rowan University. These instances occur when they are integrated into one\u27s position and or department, and through committee involvement at the university level. Outside of these instances cross collaboration often occurs in silos. While this study found that resident students are not currently impacted, it is beneficial to develop more intentional practices that incorporate cross-campus collaboration in order to more comprehensively benefit students

Factors that Affect the Decision-Making Process of African American Students

There is only a 9 % representation of African American students on colleges campuses across the country compared to 72.9% of Caucasian students. There are many reasons that affect African American students\u27 decisions to participate in higher education. Colleges across the country are making strides to recruit minority students. However, in order for colleges to increase their minority enrollment, particularly with African American students, they must understand the factors that affect African Americans students\u27 decisions to participate in higher education. Personal, economic, academic, and social factors were examined to understand African American students\u27 reasons for enrolling or not enrolling in post-secondary education institutions

Relación entre el estilo personal del terapeuta, estilo de apego y factores de personalidad del terapeuta

The aim of this study is to analyze the relationship between the personal style of the therapist, attachment style and personality trait. It was used the personal style of the therapist questionnaire (PST – Q), the Argentinean attachment inventory and the big five inventory. The study sample consisted of 120 psychotherapists average age of 36.28 years (SD = 9.65), and the average years of experience was 7.90 years (SD = 8.04). The analysis of the results showed that there is a positive, significant and low intensity between the personality factor of openness to experience and personal style of involvement, a negative correlation, significant and of medium intensity between low extraversion factor correlation and mode not anxious romantic attachment and a significant positive relationship between the low–intensity factor neuroticism personality and how anxious romantic attachment. El objetivo de este estudio es analizar la relación entre el estilo personal del terapeuta, estilo de apego y factores de personalidad del terapeuta. Para lo cual se aplicó el cuestionario del Estilo Personal del Terapeuta (Fernández Álvarez & García, 1998), la escala argentina de apego (Carreras, Brizzo, Gonzalez, Mele & Casullo, 2008) y el Big Five Inventory (Castro Solano & Casullo, 2001). La muestra del estudio estuvo compuesta por 120 psicoterapeutas de edad promedio de 36.28 años (DE = 9.65), y los años de experiencia promedio fueron de 7.90 años (DE = 8.04). El análisis de los resultados mostró que existe una correlación positiva, significativa y de baja intensidad entre el factor de personalidad de apertura a la experiencia y el estilo personal de involucración, una correlación negativa, significativa y de mediana-baja intensidad entre el factor de extraversión y el modo de apego no romántico ansioso, y una relación positiva significativa de baja intensidad entre el factor de personalidad neuroticismo y el modo de apego romántico ansioso.

Contribución al conocimiento del comportamiento de nidificación de especies argentinas de Sphecidae (Insecta, Hymenoptera)

Creo importante resumir en un último capítulo las novedades y conclusiones presentadas en las diferentes secciones de esta tesis. En su introducción, así como en otras secciones planteé la posibilidad de aportar datos sobre dos aspectos relacionados con los Hymenoptera: la diferenciación de nichos ecológicos, y la evolución del comportamiento social; también me prepuse aclarar la bionomía de especies de aquellos géneros cuyos integrantes no habían sido estudiados anteriormente así como describir ciertos comportamientos insuficientemente detallados o mal interpretados por otras autores. Todos estas objetivos fueron cumplidos aportando además algunos métodos de estudio nuevos. Describo por primera vez el comportamiento de nidificación de especies de los géneros Trichostictia, Selman, Editha y Hemidula, a los que debo sumar Zyzzyx, ya que los conocimientos sobre la única especie de este género eran en su mayor parte erróneos. La etología de los bembicini era una de las que menos se conocía en Sphecidae, pero el aporte hecho por esta tesis revierte la situación, de manera que ahora se conocen datos etológicos sobre especies pertenecientes a 14 de los 15 géneros incluidos. A estos datos deben agregarse los presentados para mas especiesde los géneros Bicyrtes, Bembix, Stictia y Rubrica, ya que de algunas había datos sobre comportamiento. Las observaciones presentadas, referidas a los géneros enumerados mas arriba,me permitieron en algunos casos detallar comportamientos particulares, aportar datos sobre la evolución hacia la sociabilidad, describir actividades no estudiadas antes en este grupo, y redondear el panorama sobre la radiación adaptativa de los Bembicini en la región Neotropical. Así, describo por primera vez detalladamente el comportamiento de desecho de presas de Rubrica nasuta, para lo que debí diseñar una celdilla artificial que permitiera la observación de las hembras bajo tierra; este estudio me permitió interpretar satisfactoriamente esta actividad y hacer una revisión de ella en Sphecidae que me posibilitó deducir el origen filogenetico de este comportamiento. Describo por primera vez en detalle la cópula de un miembro de los Bembicini (Zyzzyx chilensis) y reviso este comportamiento en Sphecidae, lo cual adquiere valor si se considera que esta revisión es la primera realizada para este comportamiento, uno de los menos observados en representantesde esta familia, Planteo por primera vez la existencia de un aprovisionamiento en masa lento, según observaciones sobre Bicyrtes simillima, a raíz de lo cual modifico la clasificación de los tipos de aprovisionamiento propuesta en la bibliografía,y fundamentalmente llamo la atención sobre la posibilidad de que este tipo sería una transición entre el aprovisionamiento en masa y el progresivo, por lo que sería fundamental para explicar el origen filogenetico del segundo. Como destaqué en la introducción, el hallazgo de avispas que presenten comportamientos de transición como el mencionado, es un hecho muy raro y muy valioso, ya que estos resultan fundamentales para explicar el paso de una a otra fase en la evolución hacia la sociabiiidad, en este caso el paso de la fase crabronoide a la bembicoide de Malyshev. A raíz de observaciones sobre comportamientos anómalos durante la espera hastael nacimiento de la larva, en Rubrica nasuta, Stictia arcuata y Hemidula singularis planteo una hipótesis sobre la importancia de este período en la aparición del hábito de atender a varias larvas simultaneamente, comportamiento poco frecuente en Sphecidae, pero estrechamente relacionado con las sociedades de otros grupos de Hymenoptera. En relación con la oviposición destaco un aporte hecho aquí, que contribuye al esclarecimiento de la transción entre la fase bembicoide y la moneduloide de Malyshev, o sea entre la oviposición en la primera presa y en la celdilla vacía: Selman notatus y Editha integra seleccionan una presa mas pequeña para depositar el huevo, la cual al parecer no sirve como alimento, y sea el paso anterior a la deposición del huevo en la celdilla vacía. La observación del comportamiento subterráneo en Rubrica nasuta me permitióaclarar la evolución del comportamiento de introducir la presa en el nido en Bembicini, tema no tratado anteriormente en la bibliografía, y que permite incluso poner de manifiesto, en el caso de Editha integra, como las ventajas adaptativas de explotar un nuevo tipo de presa, llevan a veces implícito el costo de una regresión evolutiva en otro aspecto del comportamiento, como es la introducción de la presa en el nido. También los datos aportados para varias especies, frecuentemente dieron lugara la revisión de otros temas, como los mecanismos de transporte de presas, laestructura de los nidos y los cierres temporales de estos (relacionado con la estructura de los nidos presento un método para obtener moldes de acrílico de ellos). También analizo la selección de presas en Bembicini, planteando ciertas hipótesis aplicables a la mayoría de las avispas predadoras oligófagas. Si bien los datos aportados en el campo de la etología pura, mencionados masarriba, son de mucho interés, creo que los Bembicini ofrecen todavía mas campo,si se considera el tema de la radiación adaptativa, es decir como los diferentescomportamientos presentados reflejan adaptaciones para la conquista de nuevos nichos ecológicos. Así se ve que en el conjunto de especies de cada género es posible distinguir por lo menos un rasgo importante, no compartido por espacies de otros géneros, y en algunos casos, cuando los datos lo permiten, analizo también las diferencias ecológicas entre especies de un mismo género. Resumiendo estos rasgos sobresalientes, puedo decir que las especies de Rubrica nidifican en suelos limosos compactos, la única de Selman en suelos arenosos con vegetación densa, y las de Hemidula en salitrales; las especies de Editha cazan lepidópteros, las de Bicyrtes cazan Heteroptera, y las de Microbembex son necrófagas; las de Zyzzyx y Trichostictia nidifican a temperaturas mas bajas que las demás, y las de Stictia ubican sus celdillas a una profundidad no utilizada por ningún otro miembro de los Bembicini. La única especie de Bembix ampliamente distribuida en el país representa en cambio un Bembicini mas típico: nidifica en arena sin vegetación, caza dípteros y construye nidos no muy profundos. En lo referente a diferencias intragenéricas, fueron estudiadas tres especies del género Bicyrtes,que se diferencian por el tamaño de la presa cazada, y por el tipo de suelo utilizado para nidificar. Este panorama general, resumido brevemente, que presenta diferencias ecológicas tan claras, muestra lo antedicho sobre el excelente campo que brindan los Bembicini para estudios sobre temas ecológicos. Paralelamente a estas observaciones llevé a cabo estudios sobre morfología comparada de las larvas, describiendo por primera vez las larvas de especies pertenecientes a géneros de los que no se sabía nada sobre este aspecto, como Editha, Selman y Trichostictia; además redescribo la de Rubrica nasuta, y describo por primera vez la de Stictia flexuosa. De este estudio surgió la necesidad de modificar el esquema filogenetico propuesto para la tribu, armado sobre la base de la morfología de los adultos solamente. Esta modificación, a grandes rasgos, involucra al género Bembix, el cual, como se ilustra en la figura 87, sería el único integrante de una línea evolutiva; dicha línea, estaría emparentada con la de los géneros exclusivamente neotropicales, pero la relación sería mas distante que en el esquema propuesto para los adultos. Dicha modificación también se apoyaría en datos sobre etología presentados en esta tesis, y en aspectos zoogeográficos.Fil: Genise, Jorge F.. Universidad de Buenos Aires.

Faster Gaussian Sampling for Trapdoor Lattices with Arbitrary Modulus

We present improved algorithms for gaussian preimage sampling using the lattice trapdoors of (Micciancio and Peikert, CRYPTO 2012). The MP12 work only offered a highly optimized algorithm for the on-line stage of the computation in the special case when the lattice modulus $q$ is a power of two. For arbitrary modulus $q$, the MP12 preimage sampling procedure resorted to general lattice algorithms with complexity cubic in the bitsize of the modulus (or quadratic, but with substantial preprocessing and storage overheads.) Our new preimage sampling algorithm (for any modulus $q$) achieves linear complexity, and has very modest storage requirements. As an additional contribution, we give a new off-line quasi-linear time perturbation sampling algorithm, with performance similar to the (expected) running time of an efficient method proposed by (Ducas and Nguyen, Asiacrypt 2012) for power-of-two cyclotomics, but without the (matrix factorization) preprocessing and (lattice rounding) postprocessing required by that algorithm. All our algorithms are fairly simple, with small hidden constants, and offer a practical alternative to use the MP12 trapdoor lattices in a broad range of cryptographic applications

Sedimentology, diagenesis and ichnology of Cretaceous and Palaeogene calcretes and palustrine carbonates from Uruguay

The Cretaceous (Mercedes Formation) and Paleogene (Queguay Formation) deposits cropping out inWand S Uruguay comprise two terrestrial limestone units that are very rich in trace fossils. The study of these units permits to propose a sedimentological model for palustrine limestones and calcretes in which the distribution of different types of trace fossils is considered. The study units include three main types of deposit: lacustrine limestones, palustrine limestones and calcretes. The lacustrine limestones are relatively homogeneous and contain gastropods, charophytes and ostracods, but no trace fossils. They were deposited in a relatively more perennial lacustrine environment. The palustrine limestones include four different facies: desiccated mudstones, nodular limestones, granular limestones and gravel-sheets. The desiccated mudstones indicate a lesser degree of pedogenic modification and the granular limestones a higher degree. The gravel-sheets are an indication of the reworking of previous limestones deposits during low lakewater levels. Most of the palustrine limestones (except the gravel sheets) contain the same bioclasts as the lacustrine limestones plus a variety of trace fossils such as Rebuffoichnus sciuttoi, Fictovichnus gobiensis and different ichnospecies of Celliforma. The calcretes are either massive (groundwater) or laminar. The massive calcretes are sandy limestones made up of a carbonate matrix and cements. The laminar calcretes (root mats), which contain alveolar septal structures, occur as centimetre-thick layers and can be seen in all types of deposit. They contain the same trace fossil association as the palustrine limestones; the massive calcretes are poorer in such fossils. The distribution of trace fossils in these environments is under strong facies control and provides good evidence of subaerial exposure and semi-arid climates. All the limestones are partially replaced and cemented by opal and quartz, but in all cases the primary structure is preserved. Silicification occurred under groundwater meteoric conditions. Overall, the limestones facies (calcretes, palustrine and lacustrine) and their lateral distribution likely reflect the existence of wetland environments in semiarid to sub-humid climates. These climatic conditions were interrupted by a period of increased precipitations, probably the Early Eocene Climatic Optimum

A CONNECTION BETWEEN MORAL IMPERATIVE AND WOMEN’S LEADERSHIP?

This paper describes a qualitative study of two school districts’ efforts to support school leaders in developing the knowledge and skills to analyze, understand, and transform system inequities. The results suggest that, despite being armed with knowledge and skills, leaders may be reluctant to act even when doing so is within the scope of their authority. This work draws from Fullan’s (2003) concept of moral imperative and examines the connection between moral imperative and women’s ways of leading. The findings have implications for educational leadership programs that seek to prepare school leaders capable of challenging and changing inequitable systems

Gadgets and Gaussians in Lattice-Based Cryptography

This dissertation explores optimal algorithms employed in lattice-based cryptographic schemes. Chapter 2 focuses on optimizing discrete gaussian sampling on "gadget" and algebraic lattices. These gaussian sampling algorithms are used in lattice-cryptography's most efficient trapdoor mechanism for the SIS and LWE problems: "MP12" trapdoors. However, this trapdoor mechanism was previously not optimized and inefficient (or not proven to be statistically correct) for structured lattices (ring-SIS/LWE), lattice-cryptography's most efficient form, where the modulus is often a prime. The algorithms in this chapter achieve optimality in this regime and have (already) resulted in drastic efficiency improvement in independent implementations.Chapter 3 digs deeper into the gadget lattice's associated algorithms. Specifically, we explore efficiently sampling a simple subgaussian distribution on gadget lattices, and we optimize LWE decoding on gadget lattices. These subgaussian sampling algorithms correspond to a randomized bit-decomposition needed in lattice-based schemes with homomorphic properties like fully homomorphic encryption (FHE). Next, we introduce a general class of "Chinese Remainder Theorem" (CRT) gadgets. These gadgets allow advanced lattice-based schemes to avoid multi-precision arithmetic when the applications modulus is larger than 64 bits. The algorithms presented in the first two chapters improve the efficiency of many lattice-based cryptosystems: digital signature schemes, identity-based encryption schemes, as well as more advanced schemes like fully-homomorphic encryption and attribute-based encryption. In the final chapter, we take a closer look at the random matrices used in trapdoor lattices. First, we revisit the constants in the concentration bounds of subgaussian random matrices. Then, we provide experimental evidence for a simple heuristic regarding the singular values of matrices with entries drawn from commonly used distributions in cryptography. Though the proofs in this chapter are dense, cryptographers need a strong understanding of the singular values of these matrices since their maximum singular value determines the concrete security of the trapdoor scheme's underlying SIS problem

Bignoniaceae Juss. na Reserva de Desenvolvimento Sustentável do Tupé: Organografia

Bignoniaceae Juss. includes ca. 110 genera and 800 species distributed in tropical and subtropical regions. It is frequently reported as one of the most important families in terms of species richness in neotropical regions. In Brazil there are 32 genera and 391 species and in the North 26 genera and 190 species. Their greatest diversity is in the habit lianescente species of plants with ascending the treetops, being an important element in the canopy of the forest, very useful as connecting between them and important to the local wildlife, but making the collection of fertile material more difficult. Although having such a large representation in the North, there are only a few studies on the morphology and anatomy of the group. Therefore one undertook the collection of data of the flower family on Sustainable Development Reserve Tupé - Manaus / AM, in order to identify and describe in detail the external and internal morphology of the species of Bignoniaceae, and present a key to identification with morphological and anatomical characters, pictorial diagrams and comments on diagnostic of, flowering and fruiting phenomenon knowledge and distribution and anatomical characters of the petiole, limbo and midrib that help to identify of sterile material and that proved to be very informative to recognize the studied species. Therefore botanical material was collected in four tracks at the Tupé Reserve in two types of environments, upland and flooded forest by monthly excursions during the period from 2002 to 2004 and biweekly from August 2011 to December 2012. Sixteen species were given the taxonomic treatment, and of these 12 were also analyzed concerning their anatomical structures. Vegetative and reproductive characters such as appearance and filling the branches, presence of glands and coverage of limbo and inter petiole regions, morphology of the pseudo stipules, apexes of tendrils, pubescence of the corolla were good characters to distinguish the species of Bignoniaceae and quite diagnostic in some cases. The most representative were Mansoa and Handroanthus, with three species each. The occurrence of H. riodocensis in Tupé Reserve is new record for the state of Amazon and in the North Brazil, there are six other new records for the Tupé Reserve. Concerning the characteristics of the leaves, the anatomy of the internal structures were more informative, such as the cross-sectional shape, the presence or not of a hollow spine the presence of the midrif vascular bundle and organization of the fibers in relation to the vascular system and proved to be satisfactory in differentiation of the species. On the other hand for the limbo it is noteworthy, the number of layers of epidermal cells and cuticle thickness, types of stomata, the number of layers of palisade parenchyma, presence of trichomes, although all observed patterns are quite common in Bignoniaceae. Furthermore, the arrangement of fibers and sclereides tissues in the subepidermal regions of the midrib were useful in the separation of species, as well as the thickness of the cuticle and epidermal ornamentation.Bignoniaceae Juss. inclui ca. 110 gêneros e 800 espécies distribuídas nas regiões tropicais e subtropicais. Frequentemente relatada como uma das famílias mais importantes em termos de riqueza de espécies nas regiões neotropicais. No Brasil ocorrem 32 gêneros 391 espécies e na região Norte 26 gêneros e 190 espécies. Sua maior diversidade está nas espécies de hábito lianescente com plantas ascendendo às copas das árvores, compondo um importante elemento no dossel da mata, bastante útil na conexão das mesmas e importante para a fauna local, porém dificultado bastante a coleta do material fértil. Apesar de tamanha representatividade na região Norte, há poucos trabalhos relativos à morfologia e à anatomia do grupo. Dessa forma, realizou-se o levantamento florístico da família na Reserva de Desenvolvimento Sustentável do Tupé – Manaus/ Am, com o objetivo de identificar e descrever detalhadamente a morfologia externa e interna das espécies de Bignoniaceae, além de apresentar uma chave para identificação com caracteres morfológicos e anatômicos, pranchas pictóricas, comentários sobre caracteres diagnósticos, fenologia da floração, frutificação, distribuição e caracteres anatômicos do pecíolo, limbo e nervura central que auxiliam na identificação de material estéril e que se mostraram bastante informativos na reconhecimento das espécies estudadas. Para tanto foi coletado material botânico em quatro trilhas da reserva em dois tipos de ambientes, terra-firme e igapó, a partir de excursões mensais no período de 2002 a 2004 e quinzenais de agosto de 2011 a dezembro de 2012. Dezesseis espécies receberam o tratamento taxonômico, dessas, 12 foram analisadas também quanto suas estruturas anatômicas. Caracteres vegetativos e reprodutivos como: aspecto e preenchimento dos ramos, presença de glândulas e indumentos no limbo e nas regiões interpeciolares, morfologia das pseudoestípulas, ápices de gavinhas e pilosidade das corolas foram bons caracteres na distinção das espécies de Bignoniaceae e bastante diagnóstico em alguns casos. Mansoa e Handroanthus foram os gêneros mais representativos, com três espécies cada. A ocorrência de H. riodocensis na RDS Tupé é registro novo para o estado e para a região Norte e mais seis novas ocorrências foram registradas para a reserva. Quanto às características da anatomia foliar, as estruturas internas do pecíolo foram mais informativas, como: o formato em corte transversal, a presença de medula oca ou não, presença de feixe vascular medular e organização das fibras em relação ao cilindro vascular se mostraram satisfatórios na diferenciação das espécies. Já para o limbo, ressalta-se o número de camadas de células epidérmicas e espessura da cutícula, tipos de estômatos, o número de camadas de parênquima paliçádico, presença de tricomas, embora todos os padrões observados no limbo sejam bastante comuns em Bignoniaceae. Além disso, a disposição das fibras e tecidos esclerenquimáticos nas regiões subepidérmicas da nervura central foram úteis na separação das espécies, assim como a espessura da cutícula e ornamentações da epiderme
