The Technology Acceptance Model and the Decision to Invest in Information Security
Security breaches have increasingly become a major threat to organizations. Nevertheless, according to recent reports, many organizations do not plan to increase spending on information security. In fact, little is known about an organization’s motivation to invest in information security. This paper uses the Technology Acceptance Model as a basis for studying factors that might motivate organizations to invest (or not to invest) in information security. It proposes that perceived usefulness and ease of use of information security influence such investment decisions. It further proposes that seven other variables influence perceived usefulness and ease of use. They are: external environment, prior information security experiences, perceived risks of not securing information, information security budget, security planning, confidence in information security, and security awareness and training. The research proposes a model of information security investment. A Delphi study and a mail survey will be used to test it
The Strategic Value of Information Security Research Participation
Although information security is an important issue, the ability to obtain subjects to participate in information security research is a challenge. The proposed research will study the link between the perceived strategic value of participating in information security research and the decision to participate. First, a perception of strategic value (PSV) instrument will be used to guide structured interviews to identify the value-drivers for such participation. Second, drawing on previous research and interview results, an instrument will be developed to assess the strategic value of participating in information security research. That instrument will then be used to answer research questions about the link between the perceived strategic value of participating in information security research and the decision to participate. The results of the study would help practitioners to understand the value of participating in information security research, thus resulting in more such studies and discoveries to enhance information security
The Strategic Value of Participating in Information Security Research: Evidence from the Finance, Healthcare, and Insurance Industries
The pervasiveness of information-based organizations, combined with the escalating number of security breaches, has resulted in the need for better information security. Nevertheless, obtaining subjects for information security research is challenging. Structured interviews were conducted with thirteen information security managers in the finance, healthcare, and insurance industries to investigate the effect of the perceived strategic value of participating in information security research on the decision to participate in such research. Subramanian and Nosek’s (2001) perception of strategic value of information systems (PSVIS) framework was used to guide the interviews. The results showed that the perceived strategic value of participating in information security research influenced the decision to participate. A model of the strategic value of participating in information security research is provided. It suggests that access to information for strategic decision making directly influences the decision to participate and two other factors (information intensity and strategic necessity) moderates that relationship.

Heterobimetallic propargyl gold complexes with p-bound copper or silver with enhanced anticancer activity
Several propargyl functionalised substrates with different heteroatoms (N, O or S) have been used for the preparation of propargyl gold(i) phosphine complexes. The complexes were prepared in high yields either by reaction of the substrate with [Au(acac)PPh3] or by reaction of [AuCl(PPh3)] with potassium hydroxide and the substrate in methanol. Several of the complexes have been characterised by X-ray diffraction showing the presence of secondary bonds such as p-stacking and aurophilic interactions. The reaction of the propargyl gold(i) phosphine complexes with [Cu(NO3)(PPh3)2] or [Ag(OTf)(PPh3)2] afforded heterobimetallic complexes with p-coordination of {Cu(PPh3)2} or {Ag(PPh3)2} to the alkyne bond. When the substituent of the propargyl unit contained more strongly coordinating pyridine moieties, [(PyCH2)2NCH2CCAuPPh3], coordination of the heterometal to the pyridine units occurred, displacing the phosphine groups and giving rise to a dimeric structure. The antiproliferative activity of the complexes against cisplatin resistant lung cancer cell line A549 was determined by MTT assay. The mononuclear gold complexes showed excellent activities with IC50 values < 14 µM. Coordination of copper of silver to the alkynyl fragment resulted in a significant increase in activity suggesting a synergistic effect between the two metal centres
Evaluation of a Coping Kit of Items to Support Children with Developmental Disorders in the Hospital Setting
This study attempted to answer the question, Do nurses perceive coping kits to be effective at meeting the needs of hospitalized children with developmental disabilities who are at increased risk for challenging behaviors? A cross-sectional post-test survey study design was used, with a convenience sample of 24 registered nurses at a Midwestern free-standing children\u27s hospital. A coping kit with simple communication cards, social script book, and distraction items (toys) was developed to enhance communication and distract children with developmental disabilities (including autism spectrum disorder) undergoing procedures in the hospital. A modified version of Hudson\u27s (2006) intervention effectiveness survey was used to measure the nurse\u27s perception of the effectiveness of the coping kit. Nurses perceived the coping kits to be effective for decreasing their patient\u27s anxiety, calming the child\u27s behavior, and increasing cooperation during procedures. The nurse can develop a plan of care that includes a coping kit to help gain cooperation with the hospitalized child with challenging behaviors

Genetic integrity of the Dark European honey bee (Apis mellifera mellifera) from protected populations: a genome-wide assessment using SNPs and mtDNA sequence data
The recognition that the Dark European honey bee, Apis mellifera mellifera, is increasingly threatened in its native range has led to the establishment of conservation programmes and protected areas throughout western Europe. Previous molecular surveys showed that, despite management strategies to preserve the genetic integrity of A. m. mellifera, protected populations had a measurable component of their gene pool derived from commercial C-lineage honey bees. Here we used both sequence data from the tRNAleu-cox2 intergenic mtDNA region and a genome-wide scan, with over 1183 single nucleotide polymorphisms (SNPs), to assess genetic diversity and introgression levels in several protected populations of A. m. mellifera, which were then compared with samples collected from unprotected populations. MtDNA analysis of the protected populations revealed a single colony bearing a foreign haplotype, whereas SNPs showed varying levels of introgression ranging from virtually zero in Norway to about 14% in Denmark. Introgression overall was higher in unprotected (30%) than in protected populations (8%), and is reflected in larger SNP diversity levels of the former, although opposite diversity levels were observed for mtDNA. These results suggest that, despite controlled breeding, some protected populations still require adjustments to the management strategies to further purge foreign alleles, which can be identified by SNPs.Pint
