AbstractDeclining lecture attendance has been an ongoing concern for educators involved in undergraduate medical education. A survey was developed (a) to gain insight into the reasons students skipped class, (b) to identify the type of study materials they were using, and (c) to determine what they thought would motivate them to come to class. The survey was sent to 317 first-year and second-year medical students, and 145 (45%) responded. Only 63% of first-year students and 53% of second-year students attended any lectures that were not mandatory. The attendance was higher for students who aspired to less competitive specialties such as pediatrics and family medicine. The most popular reasons for not coming to class were related to the efficiency of information intake and instructor or class style. The most heavily used resources (> 60%) were materials or recorded lectures provided by the instructor. The second-year students also heavily used outside study materials for Board exams, such as Pathoma (50%). Students’ ideas for what might increase their attendance suggest that they perceive that the lectures may not prepare them for Board exams, and they would like faculty to address Board related content more often in class and on assessments. Respondents also suggested that teaching practices might be improved through faculty development. Faculty awareness of and references to Board exam content, embedded in strong teaching practices, may help students find more value in live lectures. Carefully designed active learning sessions may change students’ minds regarding the relevance and value of these sessions.

Preservation of library materials or library collections is an effort made so that library materials can be used by future generations. This paper describes the "Malaysian" binding method used by the Sub Division of Technical Binding Materials of the National Library of Indonesia in preserving the collection of periodicals such as tabloids and newspapers. Apart from that, this paper also describes some of the advantages and disadvantages seen in the use of the "Malaysian" method as well as the early history of using this method in preserving the collection of periodicals in the National Library of Indonesia. This writing aims to make readers, especially library managers, know and gain insight into the "Malaysian" binding method. This writing method is through descriptive research with a qualitative approach. Methods of data collection are carried out through the field research, interviews, and literature study. The results show that the National Library of Indonesia uses this method after studying it from Malaysia in May 1990. From observations it is also known that this method has several advantages, namely the binding result is stronger, the collection is more preserved, the binding can be assembled and has an aesthetic side. Meanwhile, the disadvantages of this binding method are that the process tends to be longer, more expensive, cannot be put on too many shelves because the collection will shift backwards, the pages tend to come off easily if the stitches are not strong enough, and can only be used in binding periodical collections.

Insight Into

The research treats letters to one’s younger (usually teen) self posted on the Internet as epistolary genre marked with peculiar linguistic and pragmatic features. Though the letters to one’s self imply intrapersonal communication, i.e. the sender is identical to the addressee, it is not how the sender perceives the situation, which is revealed by the use of pronouns (I for the sender and you for the younger self). However, these two may merge and then we appears to refer to the author’s younger and current selves. Another feature of the letters is roles assumed by the addressors. They may occur as a mentor to their rebellious and anxious younger self, which correlates with the purpose of the letter – giving advice. Alternatively, the authors may position themselves as omniscient fortune-tellers who step in in times of trouble to offer support to their teen self by telling what is there to come. Each of the two roles and purposes correlates with specific language means. The mentor role turns the letter into a lesson where the Imperative Mood prevails. The role of a fortune-teller transforms the letter into an autobiographical sketch told in a bizarre way: the author shifts past events into the future with the help of deictic markers (e.g., today, this) and tenses (e.g., future tenses or their synonyms such as constructions to be about to and to be going to). The letters to one’s younger self that contain an autobiographical component provide the researcher with an insight into the process of identity construction, since they show how one endows identity with continuity and bridge the divide between one’s teen and adult selves. In addition, the letters meant as advice deliver the culture specific idea of what ‘a good life’ is: they are written to guide their actual intended audience, i.e. Internet (teen) users, in modern society and inform them of true values and right choices.

Secondary active transporters, such as those that adopt the leucine-transporter fold, are found in all domains of life, and they have the unique capability of harnessing the energy stored in ion gradients to accumulate small molecules essential for life as well as expel toxic and harmful compounds. How these proteins couple ion binding and transport to the concomitant flow of substrates is a fundamental structural and biophysical question that is beginning to be answered at the atomistic level with the advent of high-resolution structures of transporters in different structural states. Nonetheless, the dynamic character of the transporters, such as ion/substrate binding order and how binding triggers conformational change, is not revealed from static structures, yet it is critical to understanding their function. Here, we report a series of molecular simulations carried out on the sugar transporter vSGLT that lend insight into how substrate and ions are released from the inward-facing state of the transporter. Our simulations reveal that the order of release is stochastic. Functional experiments were designed to test this prediction on the human homolog, hSGLT1, and we also found that cytoplasmic release is not ordered, but we confirmed that substrate and ion binding from the extracellular space is ordered. Our findings unify conflicting published results concerning cytoplasmic release of ions and substrate and hint at the possibility that other transporters in the superfamily may lack coordination between ions and substrate in the inward-facing state.

With the increasing globalization of the business world, websites have become ever more important tools in international business. After the invention of websites, researchers have begun to analyze the websites as they have for traditional communication channels. Websites, as the communication medium of global firms, are not culturally neutral mediums. Website components should be analyzed very carefully in terms of their interaction with cultural issues to come up with culturally adapted websites. In this chapter, 114 studies on culture and websites are critically reviewed, and selected papers among them from a variety of areas such as marketing, communications, management, information technologies, and others, are analyzed in detail to consolidate the existing knowledge and approaches. This chapter aims to analyze how scholarly research on the interaction of culture and websites has developed. The studies are categorized according to the framework developed and selected. Forty of them are discussed in detail under some subcategories. A number of conceptual and methodological issues that deserve more attention are discussed to fulfill the high potential of websites. A state-of-the-art review of several innovative advances in culture and websites is provided to stimulate new streams for future research, and future research recommendations are proposed at the end of the chapter.

Magnetoelectric (ME) materials composed of magnetostrictive and piezoelectric phases have been the subject of decades of research due to their versatility and unique capability to couple the magnetic and electric properties of the matter. While these materials are often studied from a fundamental point of view, the 4.0 revolution (automation of traditional manufacturing and industrial practices, using modern smart technology) and the Internet of Things (IoT) context allows the perfect conditions for this type of materials being effectively/finally implemented in a variety of advanced applications. This review starts in the era of Rontgen and Curie and ends up in the present day, highlighting challenges/directions for the time to come. The main materials, configurations, ME coefficients, and processing techniques are reported.

ABSTRACT β-Aminopeptidases have the unique capability to hydrolyze N-terminal β-amino acids, with varied preferences for the nature of β-amino acid side chains. This unique capability makes them useful as biocatalysts for synthesis of β-peptides and to kinetically resolve β-peptides and amides for the production of enantiopure β-amino acids. To date, six β-aminopeptidases have been discovered and functionally characterized, five from Gram-negative bacteria and one from a fungus, Aspergillus. Here we report on the purification and characterization of an additional four β-aminopeptidases, one from a Gram-positive bacterium, Mycolicibacterium smegmatis (BapAMs), one from a yeast, Yarrowia lipolytica (BapAYlip), and two from Gram-negative bacteria isolated from activated sludge identified as Burkholderia spp. (BapABcA5 and BapABcC1). The genes encoding β-aminopeptidases were cloned, expressed in Escherichia coli, and purified. The β-aminopeptidases were produced as inactive preproteins that underwent self-cleavage to form active enzymes comprised of two different subunits. The subunits, designated α and β, appeared to be tightly associated, as the active enzyme was recovered after immobilized-metal affinity chromatography (IMAC) purification, even though only the α-subunit was 6-histidine tagged. The enzymes were shown to hydrolyze chromogenic substrates with the N-terminal l-configurations β-homo-Gly (βhGly) and β3-homo-Leu (β3hLeu) with high activities. These enzymes displayed higher activity with H-βhGly-p-nitroanilide (H-βhGly-pNA) than previously characterized enzymes from other microorganisms. These data indicate that the new β-aminopeptidases are fully functional, adding to the toolbox of enzymes that could be used to produce β-peptides. Overexpression studies in Pseudomonas aeruginosa also showed that the β-aminopeptidases may play a role in some cellular functions. IMPORTANCE β-Aminopeptidases are unique enzymes found in a diverse range of microorganisms that can utilize synthetic β-peptides as a sole carbon source. Six β-aminopeptidases have been previously characterized with preferences for different β-amino acid substrates and have demonstrated the capability to catalyze not only the degradation of synthetic β-peptides but also the synthesis of short β-peptides. Identification of other β-aminopeptidases adds to this toolbox of enzymes with differing β-amino acid substrate preferences and kinetics. These enzymes have the potential to be utilized in the sustainable manufacture of β-amino acid derivatives and β-peptides for use in biomedical and biomaterial applications. This is important, because β-amino acids and β-peptides confer increased proteolytic resistance to bioactive compounds and form novel structures as well as structures similar to α-peptides. The discovery of new enzymes will also provide insight into the biological importance of these enzymes in nature.
