Adapting tam and ECT: continuance intention of e-shopping in Saudi Arabia

The objective of this study is to clarify the theoretical problem and identify factors that could explain the level of continuance intention of e-shopping in context of Saudi Arabia. The study proposes a revised technology acceptance model that integrates expectation confirmation theory to measure age differences with regard to continuance online shopping intentions. Structural equation model confirms model fit. The research findings confirm that Perceived usefulness, enjoyment, and subjective norms are determinants of online shopping continuance. The structural weights are mostly equivalent between the young and old groups, but the regression path from subjective norms to perceived usefulness is not invariant, with that relationship being stronger for the younger respondents. This research moves beyond online shopping intentions and includes factors affecting online shopping continuance. The model explains 65% of the intention to continue shopping online. The research findings suggest that online strategies cannot ignore either the direct and indirect effects on continuance intentions

The Use of Lexical Cohesion Elements in the Writing of ESL Learners

This study investigated the use of lexical elements of cohesion in the essay writing of students of English as a Second Language. Two hundred essays of final year students of the University of Nigeria, Nsukka were collated and analyzed by the researchers in order to identify the lexical elements used to achieve cohesion in writing. The result showed that students used three lexical elements as postulated by Gutwinski in varying degrees in their writings. These include: repetition, synonyms, and lexical sets (collocations). Students tended to use more of repetitions and made minimal use of synonyms and lexical sets to achieve cohesion in writing. This has led to poorly written essays by students. It also implies that lexical cohesion elements should be taught in schools to enable students use them appropriately in writing

WHAT MAKES URBAN FOOD POLICY HAPPEN? Insights from five case studies

The objective of this report is to provide insights into the factors that enable the development and delivery of urban food policies and how these enablers can be harnessed and barriers overcome. By exploring a series of case studies, the report shares lessons that cities of all sizes and at all stages of food policy development — from small towns that are taking their first steps in designing food-related policy, to big cities that are striving to maintain highly-developed, integrated policies — can learn from as they work to improve their food system

Retransmission of hydrometric data in Canada

The author has identified the following significant results. The project continues to demonstrate the feasibility of transmitting hydrometric data to polar orbiting spacecraft and using these data operationally. All elements on the system are functioning well

Listening to galaxies tuning at z ~ 2.5 - 3.0: The first strikes of the Hubble fork

We investigate the morphological properties of 494 galaxies selected from the GMASS survey at z>1, primarily in their optical rest frame, using HST images, from the CANDELS survey. We propose that the Hubble sequence of galaxy morphologies takes shape at redshift 2.5<z<3. The fractions of both ellipticals and disks decrease with increasing lookback time at z>1, such that at redshifts z=2.5-2.7 and above, the Hubble types cannot be identified, and most galaxies are classified as irregular. The quantitative morphological analysis shows that, at 1<z<3, morphological parameters are not as effective in distinguishing the different morphological Hubble types as they are at low redshift. No significant morphological k-correction was found to be required for the Hubble type classification, with some exceptions. In general, different morphological types occupy the two peaks of the rest-frame (U-B) colour bimodality of galaxies: most irregulars occupy the blue peak, while ellipticals are mainly found in the red peak, though with some level of contamination. Disks are more evenly distributed than either irregulars and ellipticals. We find that the position of a galaxy in a UVJ diagram is related to its morphological type: the "quiescent" region of the plot is mainly occupied by ellipticals and, to a lesser extent, by disks. We find that only ~33% of all morphological ellipticals in our sample are red and passively evolving galaxies. Blue galaxies morphologically classified as ellipticals show a remarkable structural similarity to red ones. Almost all irregulars have a star-forming galaxy spectrum. In addition, the majority of disks show some sign of star-formation activity in their spectra, though in some cases their red continuum is indicative of old stellar populations. Finally, an elliptical morphology may be associated with either passively evolving or strongly star-forming galaxies.Comment: 27 pages, 16 figures, 5 tables. "Morphological atlas" in the appendix.

Terra incognita—cerebellar contributions to neuropsychiatric and cognitive dysfunction in behavioral variant frontotemporal dementia

Although converging evidence has positioned the human cerebellum as an important relay for intact cognitive and neuropsychiatric processing, changes in this large structure remain mostly overlooked in behavioral variant frontotemporal dementia (bvFTD), a disease which is characterized by cognitive and neuropsychiatric deficits. The present study assessed whether degeneration in specific cerebellar subregions associate with indices of cognition and neuropsychiatric performance in bvFTD. Our results demonstrate a relationship between cognitive and neuropsychiatric decline across various domains of memory, language, emotion, executive, visuospatial function, and motivation and the degree of gray matter degeneration in cerebellar lobules V–VII. Most notably, bilateral cerebellar lobule VII and the posterior vermis emerged as distinct for memory processes, the right cerebellar hemisphere underpinned emotion, and the posterior vermis was highlighted in language dysfunction in bvFTD. Based on cortico-cerebellar connectivity maps, these findings in the cerebellum are consistent with the neural connections with the cortices involved in these domains in patients with bvFTD. Overall, the present study underscores the significance of cortical-cerebellar networks associated with cognition and neuropsychiatric dysfunction in bvFTD
