凭保函放货与凭指示放货对承运人的影响

无单放货是长期困扰海上货物运输实践的重要问题。无单放货保函没有改变无单放货的违法性,承运人应对正本提单持有人承担第一性责任;《鹿特丹规则》下凭指示放货的规定将一定条件下的无单放货行为合法化并为承运人创设了新的诉权,但承运人对无单放货承担第一性责任的法律地位没有变化。     

Pedagogical shift in the twenty-first century: Preparing teachers to teach with new technologies

ABSTRACT

The expectation in education today is that pre-service teachers should graduate from teacher education adequately prepared to teach with Information Communication Technologies (ICTs) that have potential to enhance curriculum delivery, hence improving quality of education. However, research shows that pre-service teachers are graduating from teacher education underequipped to teach with ICTs. The aim of this study is to understand why, given the deployment of ICTs for teaching and learning in teacher education, the new teachers remain underprepared to teach with ICTs. Qualitative research approach was employed in this study, whereby randomly selected pre-service teachers were interview respondents. Written reflections on their preparation to teach with ICTs also formed part of the data collected. Technological Pedagogical and Content Knowledge (TPACK) theory was embraced to guide the study. Analysis of the data shows that the main contributing factor of the new teachers’ under-preparedness to teach using ICTs is the quality of instruction they receive during their training.     

Intensive mode delivery of a neuroanatomy unit: Lower final grades but higher student satisfaction

In 2011, Macquarie University moved to a three‐session academic year which included two 13‐week sessions (traditional mode) and one seven‐week session (intensive mode). This study was designed to compare the intensive and traditional modes of delivery in a unit of undergraduate neuroanatomy. The new intensive mode neuroanatomy unit provided the same quantity and quality of material to the same standard, delivered by the same teachers and over the same total hours, but in a shorter timeframe. All students enrolled in session 2 (traditional mode) and session 3 (intensive mode) were invited to participate in this study. The main outcome measures were the final course grades and level of satisfaction with the course. Although there was no significant difference between the two cohorts in self‐rated level of knowledge (P = 0.148), the traditional mode cohort achieved significantly higher final grades compared to the intensive mode cohort (P = 0.001). Similarly, the distribution of final grades was also different between the two cohorts. The two cohorts were equally satisfied with the unit overall, and with the lectures and tutorials. However, the intensive mode cohort was more satisfied with the laboratory practical classes compared to the traditional mode cohort (P < 0.001). Thus this study demonstrates that in the case of neuroanatomy, which is high in content, when the course is taught to the same standards as exist in the traditional mode of delivery, the students do not do as well even though they enjoy the course equally.

Known Knowns and Known Unknowns

Abstract

Health care professionals often request information delivered stat. Patient treatment is urgent. Any hospital library, large or small, that uses Internet document delivery (IDD) systems can place information in the hands of the health professional faster. Libraries that use Internet document delivery technologies can provide health care professionals with information more quickly. Ultimately, it could reduce the length of a hospital stay and reduce health care costs. However, hospital libraries are faced with significant barriers that prevent them from utilizing electronic document delivery systems. docMD successfully overcame barriers and allowed small and/or rural hospital libraries to take advantage of the benefits of electronic document delivery that larger libraries have enjoyed for over a decade. It provides health professionals affiliated with smaller hospitals an equal opportunity to access professional literature quickly in order to make quicker, well-informed patient care decisions. The docMD pilot project investigated, eliminated the barriers and provided IDD services to eleven small and rural hospital libraries using a centralized document mediation center. This paper provides background information, describes the creation of the docMD service delivery model and discusses possible future project outcomes.     

UCF Library Express: Planning a Faculty Delivery Service

As it becomes increasingly difficult to demonstrate the worth of the library to the academic community, gate counts and usage statistics are no longer enough. Showing the impact the library has on the community requires planning new services with outcome measurement from the start. This article outlines a project plan for launching a faculty book delivery service at the University of Central Florida's John C. Hitt Library using Rhea Rubin's (2006) Outcome Measurement model. The article reviews the relevant literature, analyzes the current internal and external climate in which the service will be implemented, discusses the logistical aspects of the service such as cost, delivery method, and staffing, and concludes by determining the goals and outcomes of the service based on these factors. This article is the first in a series of three articles that together make up an entire project planning and management document, including planning, marketing, and assessing the service. The plan in its entirety provides an example of how to apply the Outcome Measurement model in an academic library setting.     

UCF Library Express: Marketing a Faculty Delivery Service

As it becomes increasingly difficult to demonstrate the worth of the library to the academic community, gate counts and usage statistics are no longer enough. Showing the impact the library has on the community requires planning new services with outcome measurement from the start. This article outlines a marketing strategy for launching a faculty book delivery service at the University of Central Florida's John C. Hitt Library using Fisher and Pride's (2006) Blueprint for Your Library Marketing Plan. It includes a review of relevant literature on marketing delivery services, service and marketing goals and outcomes, target audiences, marketing messages, message delivery strategies, marketing budget, and management of staff responsibilities. This article is the second in a series of three articles that together make up an entire project planning and management document that is based on Rhea Rubin's (2006) Outcome Measurement model. The plan in its entirety provides an example of how to apply the Outcome Measurement model in an academic library setting.     

Document delivery and resource sharing: A collaborative consortium approach by Indian agricultural libraries

Indian Agricultural Libraries are exploring new ways and collaborations to fullfil the information need of their patrons through resource sharing and delivering documents using online platform accessible 24X7. The article discusses Inter Lendig and Document Delivery Services (DDR) facilitated through a collaborative consortium Journal Gateway called CeRA under Indian National Agricultural Research System. CeRA the (Consortium for e-Resources in Agriculture) provides a platform for online acess to e-journals and inter lending. DDR Services has been established to share resources subscribed by individual libraries as well as consortium journals using the web portal. The article also discusses of the use of DDR services by patrons of the first Indian Agricultural University in the country. Reports that the student community were most active in using the platform for inter library loan and document request in comparison to the faculty researchers who were less dependent on document from other libraries.     

Changing Strategies for Information Delivery: Theory into Practice

ABSTRACT

Many events over the past decade have jeopardized the library's ability to fulfill its basic mission resulting in a shift of information delivery paradigms. Interlibrary loan, document delivery and resource sharing have become essential rather than peripheral and funding patterns are reflecting this philosophical shift. There is renewed interest in cooperative collection development and multiple options for meshing document delivery with an existing ILL program. Within this environment under a redefined mission statement, the Rasmuson Library, University of Alaska Fairbanks, addresses these shifting paradigms and has implemented a program to meet the information needs of its patrons.
