While many studies have found that perceived usefulness-an extrinsic motivator-is the strongest determinant of using utilitarian systems, others have found that it is less important than perceived enjoyment-an intrinsic motivator-in predicting hedonic system usage. In light of these interesting but mixed findings, our research applies the motivation theory to investigate the effects of extrinsic and intrinsic motivators on system-use behavior in utilitarian, hedonic, and dual-purposed contexts. We then construct associated hypotheses and empirically test them by analyzing data collected from the literature. The results generally confirm our prediction that, in the context of utilitarian systems, extrinsic motivators are more important than intrinsic motivators, whereas, in the context of hedonic systems, intrinsic motivators play a more critical role than extrinsic motivators. The results thus substantiate our contention that, when information systems vary from utilitarian to hedonic, the most important determinants shift from extrinsic to intrinsic motivators. This paper contributes not only to a new application of the motivation theory to IT adoption, but also to an integrated and in-depth analysis of motivators, which may reorient IS scholars toward potentially more fruitful avenues for studying user behavior.

Child Abuse and Neglect | Year: 2011
Objective: Analysis of the validity and implementation of a child maltreatment actuarial risk assessment model, the California Family Risk Assessment (CFRA). Questions addressed: (1) Is there evidence of the validity of the CFRA under field operating conditions? (2) Do actuarial risk assessment results influence child welfare workers' service delivery decisions? (3) How frequently are CFRA risk scores overridden by child welfare workers? (4) Is there any difference in the predictive validity of CFRA risk assessments and clinical risk assessments by child welfare workers? Method: The study analyzes 7,685 child abuse/neglect reports originating in 5 California counties followed prospectively for 2 years to identify further substantiated child abuse/neglect. Measures of model calibration and discrimination were used to assess CFRA validity and compare its accuracy with the accuracy of clinical predictions made by child welfare workers. The extent of use of an override feature of the CFRA and child welfare worker reliance on CFRA risk scores for making service decisions were analyzed. Results: Imperfect but better-than-chance predictive validity was found for the CFRA on a range of measures in a large temporal validation sample (n= 6,543). For 114 cases where both CFRA risk assessments and child welfare worker clinical risk assessments were available, the CFRA exhibited evidence of imperfect but better-than-chance predictive validity, while child welfare worker risk assessments were found to be invalid. Child welfare workers overrode CFRA risk assessments in only 114 (1.5%) of 7,685 cases and provided in-home services in statistically significantly larger proportions of higher- versus lower-risk cases, consistent with heavy reliance on the CFRA. Conclusions/practice implications: Until research identifies actuarial models exhibiting superior predictive validity when applied in every-day practice, the CFRA is, and will be a valuable tool for assessing risk in order to make in-home service-provision decisions. © 2011 Elsevier Ltd.

Fundamental particles of nature can be characterized by their individual properties such as electric charge, mass, and spin. This last property, spin angular momentum, appears to determine whether a particle falls into one of two general categories. Particles with integer valued spin are called bosons, and those with half-integer valued spin are called fermions. The boson or fermion distinction has a remarkable effect on the statistical behavior of particle groups. For example, an unlimited number of bosons (such as photons) can occupy the same quantum state, but only a single fermion (such as an electron) can occupy a specific state. These differences in properties result in vastly different macroscopic behaviors. The distinction between a boson an a fermion is important for the structure of the periodic table of the elements, the degree to which atoms interact with each other during collisions, and even the stability of matter in everyday objects. This research aims to answer the question: are there exceptions to the general rule which links spin to the characterization of a particle as a boson or fermion? Researchers at California State University East Bay will probe the fundamental properties of light (a spin-1 particle) and explore whether it, a boson, ever exhibits any fermion-like behavior. Such a discovery would provide a new direction for the theoretical development of the basic axioms of physics and supply an essential ingredient to a more fundamental view of the world.
Experimental searches for violations of the spin statistics theorem (SST) test fundamental assumptions of quantum field theory, such as local Lorentz invariance. For this research, researachers will constrain the SST-forbidden two-photon transition rate between the ground J=0 and excited J=1 states in atomic strontium. A two-photon transition between these two states would possess total angular momentum J=1, which is an exchange-antisymmetric (fermionic) state forbidden by the SST. This new experimental search is motivated by an expected three orders of magnitude increase in sensitivity over previous searches. This increase is made possible by using laser-cooled strontium atoms and separate detection and excitation regions, reducing the leading systematic effect, scattered light. This work will take place at an undergraduate institution and will directly engage undergraduate students in hands-on research. This research program will especially benefit the diverse student body at California State University East Bay, where nearly two-thirds of students are women, over sixty percent are first-generation college students, and over seventy-five percent are underrepresented minorities.

The California State University, East Bay (CSUEB) Noyce Scholars Program Phase II (NSP II) is building on and expanding Phase I efforts to recruit and support academically successful senior mathematics and science majors and STEM professionals in completing a credential program and becoming highly effective teachers in high needs, urban schools. This four-year joint project, in collaboration with K-12 districts across Alameda and Contra Costa counties, supports 32 new math and science teachers (16 scholarships in year 2 and 16 in year 3) and focuses on two areas: 1) continuing to increase the number of middle and high school math and science teachers obtaining their credentials at CSUEB and 2) informing understanding of how best to attract, prepare, and provide ongoing support in order to retain highly effective STEM teachers by expanded evaluation of program efforts and the effectiveness of participating scholars. The NSP II is significant in its focus on the early recruitment of teacher candidates who are highly qualified in disciplinary areas.
The East Bay Area, which includes Alameda and Contra Costa Counties, supports an ethnically and racially diverse population. STEM professionals are in high demand but there are significant shortages in the workforce of those possessing competence in science and math. The future economic health of the region depends increasingly on an educational system capable of preparing teachers to respond successfully to the needs of students who require intensive and effective educational programs in science and math. The Noyce scholars furnish the tools to their students that enable underrepresented groups to be competitive in the workforce.

Our research program encompasses two different projects. The first project is an experimental search for a long-range interaction between atomic spins and the mass of the Earth. Such an interaction could arise due to a heretofore undiscovered fifth force or if gravity, as opposed to being a purely tensor interaction as assumed in general relativity, has a scalar/pseudoscalar component. Recent theoretical work has shown that such interactions could be the cause of the accelerating expansion of the universe, commonly attributed to dark energy. Our experiment seeks to detect this effect by simultaneously measuring the spin precession of two isotopes of rubidium using laser spectroscopy. Our experiment aims to improve experimental sensitivity to long-range spin-mass interactions by 1-3 orders of magnitude. Our second project focuses on development of a prototype sensor for the Global Network of Optical Magnetometers for Exotic physics (GNOME), an array of geographically separated, time-synchronized ultrasensitive atomic comagnetometers that will search for correlated transient signals heralding new physics. The GNOME would be sensitive to nuclear and electron spin couplings to various exotic particles and fields. To date, no such search has ever been carried out, making the GNOME a novel experimental window on new physics. A specific, feasible example of new physics detectable with the GNOME, presently unconstrained by astrophysical observations and laboratory experiments, is a network of domain walls of light pseudoscalar fields.
Our present understanding of fundamental physics is confronted by a number of deep mysteries: the origin of the matter-antimatter asymmetry of the universe, the nature of dark energy, and the nature of dark matter. Our experiments, conducted in laboratories on Earth, use precise measurements of atomic spins to test several hypotheses that might explain these mysteries. It has been proposed that if our present theory of gravity is incomplete, additional components of gravity could both generate the dark energy pushing the universe apart and produce an excess of matter over antimatter after the Big Bang. These additional components of gravity would also cause atomic spins to precess in the Earths gravitational field, the effect for which our experiment will search. A possible explanation of dark matter is a network of invisible galactic-scale domain walls that store considerable mass and energy. These invisible domain walls would exert a small torque on atomic spins that could be detected when the Earth passes through a wall. We are building a prototype sensor sensitive to such torques from domain wall-crossing events. An array of time-synchronized sensors based on our prototype will search for transient signals of astrophysical origin heralding such new physics. Our research is being carried out at a public undergraduate institution with a diverse student body, providing hands-on experience in state-of-the-art experimental physics to many undergraduate students (including a significant number of women and underrepresented minorities).

The Faculty and Undergraduate Research Student Teams (FURST) program brings together small research groups comprised of undergraduate students and faculty from primarily undergraduate institutions (PUI) in order to provide them with a year-long research experience. The program also provides a one month long intensive summer immersion for its participants at an established summer REU site at Fresno State. FURST students get an opportunity to participate in professional workshops, presentations and academic discussions along with the REU students, whereas FURST faculty can take advantage of an on-site, in-person research collaboration with their peers within the FURST program. The programs main goal is to foster both student and faculty research at PUIs, with the specific goal of producing student and faculty authored publications, as well as presentations. The program is designed to be inclusive and accessible to teams from institutions with varying research focus and support, in order to mitigate cultural changes at institutions which may not consider research a quintessential component of higher education.
FURST students will be working on open problems in mathematics under the guidance of their faculty mentors. Research topics include community detection problems in networks, expanding the framework and analysis of the cop and robber game, the use of coarse Ricci curvature in data analysis and interpolation problems, the study and solution of the non-linear Riccati-Ermakov equation, as well as other non-linear dispersive partial differential equations. Strengthening their background in the selected research topic through readings and lecture at their home institutions will prepare FURST students to engage in research at the same speed as the REU students during the immersion phase. Students will be expected to submit the end product of their research for publication in a peer reviewed journal. FURST faculty will engage in solving open problems in their area of research while building collaborations with faculty at other institutions. Faculty are also expected to produce publishable work as a result of participating in the program. In accordance with the stated goals, the program will improve access to research for students at PUIs, where such opportunities are typically limited. It will also (re)-energize faculty at PUIs so that they remain active in research. By doing so, FURST will help transform the research culture at the participating institutions, especially since the bulk of the research activities will take place at FURST teams home institutions. While FURST student participants will learn skills through the program that are invaluable in graduate school and in the scientific workplace, the program will broadly impact the students at the involved PUIs by demonstrating to them (through student talks and presentations) that research can be part of the undergraduate educational experience. Finally, through the immersion in an active REU site, FURST students will gain exposure to the workings of an REU program, and will be able to make better informed choices about applying to REU as a potential next step in their academic development.

Vanuatu is a group of 80 islands located in the South Pacific, situated roughly equidistant from New Caledonia, Fiji, and the Solomon Islands, all of which are globally important biodiversity hotspots. Despite its significance as a treasure trove of biodiversity, Vanuatus plants and fungi remain poorly documented, leaving a significant gap in our knowledge of regional biodiversity compared with neighboring island countries, all of which have active or completed flora surveys. The few existing plant surveys in Vanuatu have focused primarily on the northern end of the archipelago. In the southern part of the country, little reliable botanical data exist, and there is great potential for new scientific discoveries. This project focuses on Tafea Province, the five southernmost islands of Vanuatu. In March, 2015, Tafea Province was the site of a catastrophic category-5 super-cyclone. Just prior to that, eight forest transects were established to characterize vegetation growth and change over time. These study sites were severely impacted by the storm, and monitoring efforts will provide an important opportunity to understand how Pacific-Island forests recover from this type of event. Along with its rich biological diversity, Vanuatu is also the most linguistically rich country in the world, with 112 languages for a total population of only 253,000; nine of these languages are found only in Tafea Province. As globalization and economic development are proceeding in Vanuatu, local languages are being replaced by English, French, and Bislama (a local Creole), and thus there is a critical need to document local languages and the botanical knowledge that is encapsulated therein. Undergraduate students will be trained in the analysis of linguistic data, and graduate students will participate in all aspects of the research and receive valuable training in tropical botany and mycology.
The researchers will complete the first comprehensive survey of angiosperms, gymnosperms, ferns, lycophytes, bryophytes, endophytic and macro-fungi, and lichens ever undertaken in Tafea Province. Surveys will be conducted using two approaches: 1) establishment of permanent monitoring transects and plots, which will allow for both vegetation analysis and dense floristic and fungal sampling, and provide an opportunity for long-term monitoring in the face of global climate change, and 2) a general collecting approach will be used across larger areas. From these data, an annotated checklist (both hard copy and online) will be assembled using the database of newly collected and historical specimens. The checklist will allow for tests of phytogeographic relationships among Vanuatu and its closest neighbors (New Caledonia and Fiji), allowing the researchers to address questions relating to levels of endemism, species distributions, and evolution of the regional flora. Because most land in Vanuatu is held under customary ownership, and local people are the stewards of their environments, the loss of biocultural knowledge is a serious threat to their ability to manage biodiversity resources sustainably. To support local environmental education efforts, the project will combine the expertise of the teams linguists and botanists to work with indigenous speakers of eight Tafean languages to document names of plants and fungi, providing a tangible linkage between biodiversity, traditional culture, and conservation. Project linguists will produce printed and digital dictionaries of indigenous plant and fungal names and will use web-based videography and story maps, which spatially link names and traditional uses of organisms onto the landscape, helping viewers visualize the connections between biodiversity, knowledge, and place, providing a complement to the botanical databases.

This project is developing an interdisciplinary technology pathway program (TPP) in data technology and applications for behavioral, social, and health science students at two California State Universities. It consists of four technical courses covering Python programming, data structures and algorithms, data technology, and an interdisciplinary senior project (or database). It will be offered as a minor degree program as part of bachelors degree programs, or as a certificate program. The TPP program will use evidence-based teaching practices that encompass effective pedagogy as well as learning communities and faculty professional development. The program will use contextualized problem-based pedagogy in which students acquire key technical knowledge and skills by solving real-world problems. Each cohort of participating students will be formed into a learning community that will include professors and industry professionals in Silicon Valley for student support and role-modeling. The engineering and computing faculty who will teach the students in this program will engage in professional development in order to learn pedagogical approaches that have been shown effective for the diverse students in the social, behavioral, and health sciences. These faculty have agreed to participate in a Faculty Learning Community throughout the academic year and a summer Technology Pathway Summer Institute.
The project is expected to generate research contributions towards the development of a technical education program for a diverse group of students and the creation of a sustainable interdisciplinary program that crosses internal organizational boundaries and links to external sponsors. If this project succeeds, it will very likely spur other campuses to develop similar programs through faculty development and dissemination plans. The ongoing evaluation of the propagation process and its outcomes will reveal valuable lessons for launching such interdisciplinary initiatives. One of the participating institutions is a minority serving institution.

Inside nearly all healthy plant leaves reside a diverse community of fungi invisible to the naked eye. These cryptic symbionts, known as foliar fungal endophytes, span hundreds of millions of years of evolutionary history, are linked to plant fitness and are thought to comprise a wealth of undocumented species and biochemical compounds. Despite their ubiquity and diversity, little is known about why different fungal endophyte species are found in different plants. Hawaiis endemic and imperiled flora provides an opportunity to collect and describe a unique set of these organisms, while determining the extent to which environment, barriers to dispersal and plant evolutionary history shape these fungal symbionts diversity and distribution across islands. PIs Amend and Perry will inventory fungal foliar endophytes from a broad selection of Hawaiis endemic plants and diverse habitats using a combination of DNA sequencing and culturing techniques.
Hawaiis fungi are almost entirely undocumented, yet are undoubtedly disappearing as quickly as Hawaiis critically endangered plants. This project will enumerate the species involved in one of the most pervasive cross-kingdom symbioses in natural and agricultural systems, while also preserving biological material for future experimentation and potential natural product discovery. Through this project, Perry and Amend will train local high school, undergraduate and graduate students in fungal taxonomy and systematics, molecular ecology and evolutionary biology.

This project will research the development and application of new Next Generation curriculum exemplars for middle school science and K-12 teacher preparation foundational level general science (collectively referred to as Next Gen curriculum materials). The project will address the need to develop middle school science curriculum that aligns with the expectations of NGSS by (1) constructing diagnostic tools to assess the alignment of curricula; (2) using the tool for existing curricula in order to field test it; and (3) systematically investigating the effectiveness of the tool. The project will use these tools to revise and test a series of middle school lessons, implement them in the classroom, and study their results. Research on the efficacy of these diagnostic tools will address specific content and evidence of learning in two domains: student middle school science learning and teacher content learning.
The project will develop curriculum diagnostic tools for middle school science. The process of development will include field testing with teachers and students in 60 classrooms (20 life, 20 physical, and 20 earth science classrooms) in high needs areas. It will employ rigorous standards in developing and applying research-based procedures to produce NGSS curriculum exemplars. The mixed methodology approach will provide in-depth information regarding the alignment of new curriculum materials to the NGSS. The rigorously analyzed and field-tested Next Generation science curriculum exemplars products produced will be broadly disseminated through state and national conferences and networks of programs with which the California State University, East Bay (CSU East Bay) and core partners are in collaboration.
