Introduction:

The EUROpean Bone Over 40 Sarcoma Study (EURO-B.O.S.S.) was the first prospective international study for patients 41-65 years old with high-grade bone sarcoma treated with an intensive chemotherapy regimen derived from protocols for younger patients with high-grade skeletal osteosarcoma.

Methods:

Chemotherapy based on doxorubicin, cisplatin, ifosfamide, and methotrexate was suggested, but patients treated with other regimens at the investigators’ choice were also eligible for the study.

Results:

The present report focuses on the subgroup of 218 patients with primary high-grade osteosarcoma. With a median follow-up of 47 months, the 5-year probability of overall survival (OS) was 66% in patients with localized disease and 22% in case of synchronous metastases. The 5-year OS in patients with localized disease was 29% in pelvic tumors, and 70% and 73% for extremity or craniofacial locations, respectively. In primary chemotherapy, tumor necrosis ≥90% was reported in 21% of the patients. There were no toxic deaths; however, hematological toxicity was considerable with 32% of patients experiencing 1 or more episodes of neutropenic fever. The incidence of nephrotoxicity and neurotoxicity (mainly peripheral) was 28% and 24%, respectively. After methotrexate, 23% of patients experienced delayed excretion, in 4 cases with nephrotoxicity.

Conclusions:

In patients over 40 years of age with primary high-grade osteosarcoma, an aggressive approach with chemotherapy and surgery can offer the probability of survival similar to that achieved in younger patients. Chemotherapy-related toxicity is significant and generally higher than that reported in younger cohorts of osteosarcoma patients treated with more intensive regimens.

The Mediterranean fruit fly Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae) is the main pest of fruit crops worldwide due to its broad distribution, direct damages, and adaptation to different hosts. Developing diets for the rearing fruit flies is essential for integrated management of this pest. Mass rearing of parasitoids, selection of preferred hosts, and mass rearing of genetically modified C. capitata strains subsidize methods of biological control, cultural control, and the sterile insect technique (SIT), respectively, depending directly on the mass rearing of the Mediterranean fruit fly. The aim of this study was to assess the effectiveness of artificial diets for rearing C. capitata larvae considering the cost of those most appropriate diets. Nine diets containing different combinations of protein and energy sources (brewer’s yeast, yeast extract, pollen, soybean extract, oatmeal, corn meal, and wheat germ) were formulated. The parameters immature development time (hatching), pupal viability (emerged adults), size and weight of pupae, and adult size (wing length) were assessed. The experiments were conducted in the laboratory under controlled conditions of temperature (26 ± 1 °C) and relative humidity (70% ± 10%). Statistical analysis was performed by using ANOVA with the Tukey’s test for comparison of means. Diets based on oatmeal and soybean extract, both added with brewer’s yeast, yeast extract, or pollen satisfactorily meet the nutritional requirements of C. capitata. Moreover, diets enriched with brewer’s yeast or yeast extract presented the lowest costs; therefore, they could be used in a continuous mass-scale rearing of C. capitata. Diets based on corn meal and soybean extract, both associated with brewer’s yeast, yeast extract, or pollen are more economical, but they should not be used for rearing C. capitata because they decrease the percentage of hatching and extend life cycle. Diets based on wheat germ and oatmeal, both added with brewer’s yeast, yeast extract, or pollen are not adequate for rearing C. capitata.

Pork consumption in Brazil is still low despite its productive importance. Relevant issues such as swine breeding, meat quality, and evaluation of aspects and attributes considered important by pork consumers at the time of purchase allows identifying consumer market demands. Moreover, physical parameters evaluation or pork cuts are suggested to certify the meat quality. The aim of this study was to identify the current situation of pig farming and determine the main aspects considered by consumers when buying pork in the Western region of Paraná state, Brazil. Furthermore, the physical properties of five pork chop brands marketed in the region were determined. Initially, an exploratory research was conducted involving ten pig farming sector professionals. This research allowed identifying that professionals understand the factors affecting meat quality and that some municipalities in the region are beyond their absorption capacity for pig production market. A descriptive research involving one hundred pork consumers showed that, although most prefer beef, 41% reported to consume pork 2 to 3 times a week. Pork chops and ribs are the preferred cuts, either fried or roasted. Details such as expiration date and federal inspection register were considered the most important aspects at the time of purchase, while price was the least important one. The meat color was the most mentioned sensory attribute. The physical analyses of five pork chop brands showed no pH difference (p > 0.05), water holding capacity, and cooking loss results, distinctive from the one observed for color (L*, a* and b*) and shearing force, which showed differences among the brands (p ? 0.05). Comparing pH and L*, it can be suggested that two brands showed normal meat characteristics, one DFD meat (pH > 6.0 and L* < 45), and other two brands PSE (pH < 5.8 and L* > 50). The research contributed to identifying features considered important by pork consumers, suggesting strategic actions to achieve greater preference and consumption index. The evaluation of physical parameters showed there is variability involved in pork chop quality as the samples were obtained from commercially different origins and under different processing and storage conditions.

Although many information has been published regarding canine urolithiasis, sensitivity of radiography, ultrasound and urinary parameters have been poorly correlated with number, size, and composition of the stones. One hundred and thirteen clinical files of dogs with diagnosis of urolithiasis were retrospectively selected. Information regarding number, appearance, location, size, and composition of the stones were noted after surgical removed. Urolithiasis data was compared with radiographs and ultrasound images and urinalysis parameters. Pure struvite was found in 42.4% and calcium oxalate in 35.6%. Survey radiographs enabled the detection of radiopaque stones and when an ultrasound examination was also performed, the sensitivity was increased. Double contrast radiography enabled identification in 100% of radiolucent stones, and allowed for size measurement and number counts in 76.9% of radiolucent stones. Crystalluria had low sensitivity (31.5%) and specificity (58.8%). Hematuria (96.3%) and leukocyturia (61.1%) were the most common parameters found. We concluded that double contrast radiography can be considered the method of choice for detection of radiolucent stones. Crystalluria is not a good parameter to detect or predict type of stone. Hematuria and leukocyturia, although non-specific findings, can be used as triage for investigation of urolithiasis.

The pancytopenia can be associated with intra and extra medullary disorders. When the etiology is not obvious, the examination of bone marrow is necessary. The study aims to report and discuss quantitative amendments in bone marrow and their causes in dogs with pancytopenia. Bone marrow aspirate was obtained from 65 dogs with pancytopenia over a period of 13 consecutive months for preparation of smears stained by Giemsa and observed in light microscopy. Five hundred cells differential count was held; and assessed myeloid:erythroid ratio, cellularity, megakaryocytes and direct parasitological examination. The data were evaluated by the Chi-square statistical test. Blood tests of 3120 canines with several clinical changes were analyzed to identify pancytopenia, which accounted for 167 (5.4%) dogs. Interpretation of quantitative characteristics was carried out from the bone marrow smear in 65 pancytopenic dogs and the etiology was established in 40 (61.5%) of these, which included infection by E. canis and L. chagasi, idiopathic aplastic anemia, chronic renal failure and co-infections. In 17 (26.2%) animals were not observed medullary changes. The most bone marrow change was observed myeloid and erythroid hypoplasia in 17 (26.2%) dogs, followed by myeloid and erythroid hyperplasia (24.6%). The myelogram association to the blood cell count allowed the identification of medullary findings and its participation on the occurrence of pancytopenia cases. The number of cases resulting from infectious diseases was 38 (58.5%) in canine assessed: significant number due to its endemic characteristic of the study region.

This study aimed to evaluate the cholesterol content, ?-tocopherol and fatty acids in the meat of Nellore young bulls or steers castrated at different ages, 13 or 18 months. The animals were confined for 100 days and slaughtered at 22 months of age. The experimental design was completely randomized with three treatments, using 12 repetitions. The levels of palmitic acid (26.39%), stearic (24.39%), myristic (3.01%) and total saturated fatty acids were not altered by sexual condition or castration age. Oleic was the fatty acid with the highest average participation in the meat (34.54%), and lower content in the meat of young bulls in relation to the castrated. The content of total unsaturated fatty acids was lower in the young bulls in relation to castrated at 18 months, which did not differ from castrated at 12 months. The content of total polyunsaturated fatty acids was increased by elevation of the castration age, being similar between young bulls and castrated at 18 months. The ratio ?6/?3 was not altered by sexual condition or castration age. Castration at the beginning of the finishing period increases the content of beneficial fatty acids to health in relation to castrated in the first third of backgrounding.

Published: December 2017

Keeping self-serve milk below 4 °C may become difficult for a food premise operator who relies on the use of insulated containers for several hours. Although milk sold in Canada is pasteurized, it may have the potential to cause illness if exposed to improper temperatures. The primary objective of this study was to demonstrate which product would be the most effective at keeping milk cold for the longest period to decrease the potential risk of foodborne illness. A survey was conducted in food premises throughout the Niagara region to determine which products were most commonly used for cold-holding milk, followed by a time-series analysis to investigate how rapidly the temperature of milk increased when stored in typical containers after 8 hours. Results showed that vacuum-insulated carafes are the most effective at cold-holding and stainless-steel carton holders are the least effective. The Niagara survey showed that 8 of 27 premises visited used these poorly insulated stainless-steel carton holders, which may be additionally susceptible to human contamination from potentially pathogenic bacteria such as Staphylococcus aureus due to their open spout.

Published: December 2017

The metasupracrustal units within the north central Chelan block of the North Cascades Range, Washington, are investigated to determine mechanisms and timescales of supracrustal rock incorporation into the deep crust of continental magmatic arcs. Zircon U‐Pb and Hf‐isotope analyses were used to characterize the protoliths of metasedimentary and metaigneous rocks from the Skagit Gneiss Complex, metasupracrustal rocks from the Cascade River Schist, and metavolcanic rocks from the Napeequa Schist. Skagit Gneiss Complex metasedimentary rocks have (1) a wide range of zircon U‐Pb dates from Proterozoic to latest Cretaceous and (2) a more limited range of dates, from Late Triassic to latest Cretaceous, and a lack of Proterozoic dates. Two samples from the Cascade River Schist are characterized by Late Cretaceous protoliths. Amphibolites from the Napeequa Schist have Late Triassic protoliths. Similarities between the Skagit Gneiss metasediments and accretionary wedge and forearc sediments in northwestern Washington and Southern California indicate that the protolith for these units was likely deposited in a forearc basin and/or accretionary wedge in the Early to Late Cretaceous (circa 134–79 Ma). Sediment was likely underthrust into the active arc by circa 74–65 Ma, as soon as 7 Ma after deposition, and intruded by voluminous magmas. The incorporation of metasupracrustal units aligns with the timing of major arc magmatism in the North Cascades (circa 79–60 Ma) and may indicate a link between the burial of sediments and pluton emplacement.

Published: December 2017

Plant transpiration, a process of water movement through a plant and its evaporation from aerial parts especially leaves, consumes a large component of the total continental precipitation (≈48%) and significantly influences global water distribution and climate. To date, various chemical and/or biological explorations have been made to tune the transpiration but with uncertain environmental risks. In recent years, interfacial solar steam/vapor generation is attracting a lot of attention for achieving high energy transfer efficiency. Various optical and thermal designs at the solar absorber–water interface for potential applications in water purification, seawater desalination, and power generation appear. In this work, the concept of interfacial solar vapor generation is extended to tunable plant transpiration by showing for the first time that the transpiration efficiency can also be enhanced or suppressed through engineering the solar absorber–leaf interface. By tuning the solar absorption of membrane in direct touch with green leaf, surface temperature of green leaf will change accordingly because of photothermal effect, thus the transpiration efficiency as well as temperature and relative humidity in the surrounding environment will be tuned. This tunable transpiration by interfacial absorber‐leaf engineering can open an alternative avenue to regulate local atmospheric temperature, humidity, and eventually hydrologic cycle.
Computational Intelligence‐Assisted Understanding of Nature‐Inspired Superhydrophobic Behavior

Published: December 2017

In recent years, state‐of‐the‐art computational modeling of physical and chemical systems has shown itself to be an invaluable resource in the prediction of the properties and behavior of functional materials. However, construction of a useful computational model for novel systems in both academic and industrial contexts often requires a great depth of physicochemical theory and/or a wealth of empirical data, and a shortage in the availability of either frustrates the modeling process. In this work, computational intelligence is instead used, including artificial neural networks and evolutionary computation, to enhance our understanding of nature‐inspired superhydrophobic behavior. The relationships between experimental parameters (water droplet volume, weight percentage of nanoparticles used in the synthesis of the polymer composite, and distance separating the superhydrophobic surface and the pendant water droplet in adhesive force measurements) and multiple objectives (water droplet contact angle, sliding angle, and adhesive force) are built and weighted. The obtained optimal parameters are consistent with the experimental observations. This new approach to materials modeling has great potential to be applied more generally to aid design, fabrication, and optimization for myriad functional materials.

Published: December 2017

Ternary NiCoFe‐layered double hydroxide (NiCoIIIFe‐LDH) with Co3+ is grafted on nitrogen‐doped graphene oxide (N‐GO) by an in situ growth route. The array‐like colloid composite of NiCoIIIFe‐LDH/N‐GO is used as a bifunctional catalyst for both oxygen evolution/reduction reactions (OER/ORR). The NiCoIIIFe‐LDH/N‐GO array has a 3D open structure with less stacking of LDHs and an enlarged specific surface area. The hierarchical structure design and novel material chemistry endow high activity propelling O2 redox. By exposing more amounts of Ni and Fe active sites, the NiCoIIIFe‐LDH/N‐GO illustrates a relatively low onset potential (1.41 V vs reversible hydrogen electrode) in 0.1 mol L−1 KOH solution under the OER process. Furthermore, by introducing high valence Co3+, the onset potential of this material in ORR is 0.88 V. The overvoltage difference is 0.769 V between OER and ORR. The key factors for the excellent bifunctional catalytic performance are believed to be the Co with a high valence, the N‐doping of graphene materials, and the highly exposed Ni and Fe active sites in the array‐like colloid composite. This work further demonstrates the possibility to exploit the application potential of LDHs as OER and ORR bifunctional electrochemical catalysts.
Das ‚politische Volontariat‘ des Arnold Clapmarius. Praktische Erfahrung und der Anschein praktischer Erfahrung als Qualifikation für die politischen Wissenschaften um 1600
Authors: Haas Philip
Published: December 2017

Arnold Clapmarius’ ‘Traineeship in politics’. Practical Experience and the Semblance of Practical Experience as a Qualification in the Field of Political Science around the Year 1600. In 1600, Arnold Clapmarius (1574–1604) was appointed the first professor for Public Law and Political Science in the Holy Roman Empire by the University of Altdorf (Nürnberg). He received this professorship though he had not yet published anything because he was a protégé of Landgrave Maurice the Learned of Hesse‐Kassel. Two newly discovered letters which were written by Clapmarius to Maurice show that the young scholar did a traineeship at the Landgrave's court to gather practical experience in politics. This was probably the reason for his appointment in Altdorf. Nevertheless, he hushed up this traineeship because it did not comply to the kind of experience that were expected from a ‘politicus’ at that time, id est military service, educational journeys, foreign languages and regional studies. Thus, this paper fills a gap of Arnold Clapmarius’ biography, and provides a new perspective on the value of practical experience in the field of political science in the Early Modern Period.

The general microscopic characteristics of nerves are described in several textbooks of histology, but the specific microanatomies of most nerves that can be blocked by anesthesiologists are usually less well known. Our objective was to evaluate the 3D reconstruction of nerve fascicles from optical projection tomography images (OPT) and the ability to undertake an internal navigation exploring the morphology in detail, more specifically the fascicular interconnections. Median and lingual nerve samples were obtained from five euthanized piglets. OPT images of the samples were acquired and 3D reconstruction was performed. The OPT technique revealed the inner structure of the nerves at high resolution, including large and small fascicles, perineurium, interfascicular tissue, and epineurium. The fascicles were loosely packed inside the median nerve and more densely so in the lingual nerve. Analysis of the 3D models demonstrated that the nerve fascicles can show six general spatial patterns. Fascicular interconnections were clearly identified. The 3D reconstruction of nerve fascicles from OPT images opens a new path for research into the microstructure of the inner contents of fascicular nerve groups and their spatial disposition within the nerve including their interconnections. These techniques enable 3D images of partial areas of nerves to be produced and could became an excellent tool for obtaining data concerning the 3D microanatomy of nerves, essential for better interpretation of ultrasound images in clinical practice and thus avoiding possible neurological complications.

Coronary balloon catheter tip damage. A bench study of a clinical problem
Authors: Barkholt Trine Ø , Ormiston John A , Ding Patricia , Webber Bruce , Ubod Ben , Waite Stephen , Webster Mark Wi
Published: December 2017

Objectives

To confirm clinically that coronary balloon catheter tips may be damaged during bifurcation treatment with side‐branch access through the side of a stent. On the bench, we aimed to assess the susceptibility of different balloon designs to damage. We compared catheter tip widths. We tested whether balloon tip flaring can cause stent distortion.

Background

We had observed that balloon catheters that failed to cross to a side‐branch frequently exhibited tip damage.

Methods and Results

We examined microscopically for damage 82 balloon tips after clinical side‐branch access. In a bench study, the forces required to compress catheter tips 0.5 mm were compared to assess susceptibility to damage. We compared tip widths of balloons of different nominal inflation diameters. We examined stents after side‐branch access for distortion. In 42 of 48 (88%) of balloon tips from patients with resistance to or failure to cross through the side of a stent there was tip damage. Even when the balloon crossed without perceptible resistance, tip damage occurred in over half of balloons 18/34 (53%). Some balloon designs were more resistant to damage than others. Tips from balloons of different nominal diameters from the same manufacturer had the same width. Stent distortion caused by damaged balloon tips is improved by kissing balloon post‐dilatation.

Conclusions

Balloon tip damage is common with crossing between stent struts. This is one cause of failure of a balloon to access a side‐branch and a new balloon should be used. If stent distortion is suspected, it should be corrected with kissing balloon post‐dilatation.
The effect of dronabinol in a male patient with anorexia nervosa suffering from severe acute urge to be physically active
Authors: Graap Holmer , Erim Yesim , Paslakis Georgios
Published: December 2017

Objective

A 27‐year‐old male suffering from chronic anorexia nervosa was admitted for inpatient psychotherapy suffering from severe urge to be physically active.

Methods

An off‐label treatment with dronabinol was initiated, to reduce his symptoms related to that urge. Several attempts to reduce symptoms including intensive psychotherapy and several psychopharmacological agents had failed in the past.

Results

Following treatment with 7.5 mg dronabinol twice a day, the patient reported a significant reduction in his acute urge to be physically active. Also eating disorder‐specific cognitions and compulsive behaviors remitted.

Discussion

Previous studies have applied much lower doses and showed no effect of dronabinol upon the urge to be physically active. Up to date, the patient reported no side effects, especially no psychotropic effects. Implications of this case report are discussed.
Reducing the stigma associated with anorexia nervosa: An evaluation of a social consensus intervention among Australian and Chinese young women
Authors: Yan Yuwen , Rieger Elizabeth , Shou Yiyun
Published: December 2017

Objective

This study examined the effectiveness of a social consensus intervention in reducing stigma toward individuals with anorexia nervosa (AN) among women from Australia and mainland China. Moreover, the different predictions of informational/normative social influence theory and the social identity approach in terms of the effectiveness of the social consensus intervention were investigated.

Method

Participants were female students from the Australian National University (n = 97) and Central China Normal University (n = 76) who reported their levels of stigma toward a fictional character with AN before and after receiving normative information regarding the attitudes of others toward people with AN. Three experimental conditions of normative information were utilized: in‐group, out‐group, and neutral.

Results

Chinese participants reported higher levels of baseline stigma across all measures than Australian participants. Social consensus was effective in reducing most types of AN stigma, and supported the social identity approach in that improvements in attitudinal, affective, and behavioral aspects of stigma were significantly greater for participants in the in‐group (but not the out‐group) versus the neutral condition. The effectiveness of the social consensus approach was not moderated by nationality.

Discussion

A social consensus approach holds potential as an additional strategy for reducing AN stigma, with its benefits extending across diverse cultural settings. Such an approach would entail ensuring that positive messages regarding people with AN are delivered by members of a valued in‐group.

Published: December 2017

Objective

To ascertain whether the prevalence of ultrasonography signs of abnormally invasive placenta (AIP) changes during pregnancy.

Methods

The present retrospective analysis included women with a prenatal diagnosis of AIP that was confirmed at delivery between January 1, 2007, and April 30, 2017, at the Department of Obstetrics and Gynaecology, Arnas Civico Hospital, Palermo, Italy. Ultrasonography signs of AIP were recorded at four different intervals during pregnancy: early first (6–9 weeks), first (11–14 weeks), second (15–24 weeks), and third trimester (25–36 weeks).

Results

There were 105 pregnancies included. Low implantation of the gestational sac was present on all ultrasonography images from the early first trimester compared with on 23 of 83 (27.7%) images from 11–14 weeks of pregnancy. The identification of loss of the clear space, placental lacunae, bladder wall interruption, and uterovesical hypervascularity all increased (all P<0.001) from the early first trimester onwards; these could all be identified in a majority of patients at 11–14 weeks of pregnancy.

Conclusions

The prevalence of ultrasonography signs suggestive of AIP varied throughout pregnancy. During the early first trimester, indicators of AIP were similar to those of a cesarean scar pregnancy; classical ultrasonography signs of AIP were already present at 11–14 weeks of pregnancy for most patients.
Exporting Software from Indonesia
Authors: Bruell Norbert
Published: December 2017

The Indonesian software industry is still in its infancy. The software exporting industry is very small. However, at least a small number of software exporters do exist and there is a potential for such an industry to develop. Characteristics of the domestic Indonesian demand: One of the highest piracy rates in the world prevent any clear market estimation; One large project by a large Corporation or Government organization has high impact on the entire market; Some sectors have excellent IT facilities and software expertise, while other are still working under “pre‐historic” conditions; Most demand is satisfied by established international software producers in tandem with international management consulting firms. A national strategy for the development of the software export industry is being formulated, but its implementation is likely to take some years to show impacts. The Indonesian Ministry of Trade and Industry is in charge of formulating the national software export policy with the following objectives: Strengthen the Internet based application infrastructure; Strengthen the IT infrastructure; Develop the local software industries; Enable Institution Capacity Building. As Indonesia is till recovering from the 1998 Asian Financial Crisis, the Government has put software export issues further down the list.
National Software Industry Development: Considerations for Government Planners
Authors: Tessler Shirley , Barr Avron , Hanna Nagy
Published: December 2017

Software presents an unusual set of problems for policy makers. As a major global industry, it has been successfully targeted by a growing number of countries for its potential to generate export revenue. At the same time, it is an essential, high‐risk, and increasingly expensive component of Information and Communications Technology (ICT)‐related programs to increase government effectiveness and to bring local firms in other industries up to globally competitive performance levels. This paper outlines the range of considerations specific to software within ICT planning and discusses government's role in accelerating and shaping that growth in support of social and economic priorities. We draw on the experience of both developed and emerging economies to argue that government should take an active role in software industry development, and to lay out the full range of possible government actions (both policies and programs). Every country's path seems to be different – the best course of action will depend on the resources available (including infrastructure and human resources), on the state of the global software industry at that specific time, and on the country's unique situation, such as languages spoken, regional or cultural ties with major markets, a tradition of entrepreneurship, or an expatriate business community.
Can E‐Marketplaces Bridge the Digital Divide? An Analysis of Two Western Australian Cases

In Australia, small and medium enterprises (SMEs), particularly rural SMEs, are perceived as being on the wrong side of the digital divide. Government at local and state levels has taken a leading role in the development of electronic marketplaces with an aim of improving SME participation. Many government departments now either own or sponsor electronic marketplaces. The aims of government agencies in creating e‐marketplaces are often motivated by regional economic development issues. Whilst government entities may think e‐marketplaces are an effective channel for implementing government policy, a number of complications can arise from this model. Despite the community development motivation, a major argument for e‐marketplace development being put forward is the economic one and this has contributed to a narrow view of the e‐marketplace concept and one, which for the time being at least, is likely to restrict its impact. Government sponsored e‐marketplaces should consider the value of on‐line business networks to share knowledge and potentially increase levels of innovation. The findings have implications for government sponsored e‐marketplace initiatives around the world.

Published: December 2017

High quality information technology (IT) support is an integral factor in the success of today's health sector. However, the medical profession is considered to be low level investors in IT when compared to other sectors. Many international comparisons look at the expenditure spent on health IT as a basis for determining how effective the systems are. This prescriptive mainly cost/benefit approach is believed to be deficient as a sole factor in evaluation procedures. The research in this study supports the notion that more systematic attention needs to be taken into evaluating the success of an IT system. A perspective noted through a process based assessment for information systems effectiveness assessment (PB‐ISAM) is therefore proposed. The method was developed and subsequently evaluated through three case organizations in the medical sector. Specific implications are drawn concerning the applicability of PB‐ISAM, conclusions are drawn from the insights gained and suggestions for further research reported.
Information Technology And Business Value in Developing Economies: A Study of Intangible Benefits of Information Technology Investments in Fiji
Authors: Prasad Acklesh
Published: December 2017

Understanding how IT investments contribute to business value is an important issue, and this assists in the efficient use of technology resources in businesses. While there is an agreement that IT contributes to business value, we are unsure of how IT contributes to business value in the wider context, including developing countries. With the view that understanding the interaction between IT resources and the users may provide better insights on the potential of IT investments, this study investigates the businesses’ perception of the intangible benefits of their IT investments. The results indicate that businesses in developing countries perceive that their IT investments provide intangible benefits, especially at the process level, and this contributes to business value.
Digital Divide Between Urban and Rural Regions in China
Authors: Fong Michelle W. L.
Published: December 2017

This research paper evaluates the development relationship between the adoption rate of Information and Communications Technologies (the Internet, mobile phone, pager, personal computer, and telephone) and per capita income gap between the urban and rural areas in China, mainly between 1985 and 2006. The Pearson's correlation coefficients suggest there has been a strong correlation in the development relationship between this income gap and the adoption of the Internet, mobile phone, personal computer, and telephone during this period. This paper also examines the adoption of these ICTs between the urban and rural regions, and probes into two pressing issues that affect the digital divide – affordability of these technologies to the rural population, and the educational level of rural users that impact upon usage capability.
The Role of Technological Frames of Key Groups in Open Source Software Implementation in a Developing Country Context
Authors: Mengesha Nigussie Tadesse
Published: December 2017

The emergence of open source software (OSS) has changed the philosophy and practice of software development, implementation and ownership; a phenomenon which also has influenced interpretations, actions and behaviors of organizational members. This research explicates the interpretations and subsequent actions of key stakeholder groups towards OSS during the implementation of an OSS‐based IS in a public sector organization in Ethiopia. Drawing upon the technological frames analytical framework, the study shows that the key stakeholder groups interpreted openness of the software and the community model of software implementation differently leading them to entertain divergent actions. Users were keen to solving operational problems via readymade IS with a third party support, while the management and technologists were focusing on the strategic importance of OSS not only to their own organization but also to the nation in general. Perception differences led to alliance formation, political processes, and change of management style. The study shows that as multiple interrelated elements shape the technological frames of groups, the relationship between frame incongruence and implementation is also complex and contextual. The study proposes technological frame analysis as an integral part of OSS implementation and a carefully crafted intervention to harness frame incongruence, if any.
Uses, Benefits and Challenges of Public Access Points in the Face of Growth of Mobile Technology

Published: December 2017

For over two decades, the use of shared Information and Communication Technology (ICT) access has been promoted as a mode for promoting access to technology, especially in developing countries, hence minimising the effects of the digital divide on those on the wrong side of the divide. Recent discourse on the momentous diffusion of mobile telephony in developing countries has questioned the rationale of promoting fixed shared access, since people are bound to prefer mobile phones over shared access points. This paper seeks to empirically explore the use of shared access points in the wake of the increasing diffusion and usage of mobile technology. We explored the actual use of shared computing facilities, the benefits users accrue from using the facilities and the challenges they face in using and in gaining benefits. We used a case study of a shared facility in a disadvantaged community in Cape Town. The study noted that the demand for the shared facilities is still high. We noted that the center is used for both instrumental and hedonic purposes. It was also noted that there are economic, social and psychological benefits from using the facilities. However, it was noted that use of the facilities is beset by a number of challenges which limit use and benefits from the usage. The paper also noted the strategies users employ to overcome the challenges.

Authors: Winley Graham Kenneth , Wongwuttiwat Jittima
Published: December 2017

Predictions about changes over the period 2005 to 2010 in the nature and structure of the IT profession in organizations operating in developed nations were tested for organizations operating in eight different organizational sectors in Thailand. Data collected in 2006 and 2011 from organizations in Thailand was used to test the predictions and to identify similarities and differences among the sectors with respect to the importance of specific knowledge and skills associated with each part of the predicted structure. The findings provide theoretical and practical insights into the development of the nature and structure of the IT profession in Thailand over the past five years and the relative importance of IT professional skills in each organizational sector.
Using Information and Communication Technologies for Enhancing the Accessibility of Agricultural Information for Improved Agricultural Production in Tanzania
Authors: Mtega Wulystan Pius , Msungu Andrew Charles
Published: December 2017

The study assessed how ICTs can enhance access to agricultural information needed for fostering agricultural production and agribusiness in Tanzania. Specifically, the study determined the role of specific ICTs in agricultural production and agribusiness and assessed the effectiveness of the commonly used ICTs in the creation and sharing of agricultural knowledge and information services. It further evaluated the factors which limit the effectiveness of ICTs in facilitating agricultural production and agribusiness in Tanzania. The study involved a mixed approach in collecting data, relying on a structured questionnaire, interviews, content analysis and observations during the data collection. Results show that radio, mobile phones, television, computers and internet have potentials to transform the sector if they are used effectively. Findings show further that not all ICTs are suitable for all categories of actors in the agricultural sector. Mobile phones and radio were preferred as communication channel among farmers while researchers and extension staff mentioned to prefer using computers and internet. Moreover, some of the ICT applications such as calls, short messaging services and sim‐banking were mentioned to be used often. From these findings it is recommended that internet and mobile service providers should widen their infrastructure and reduce tariffs associated with usage of their services so as to increase the number of users of their services. This can enable more information exchange among agriculture stakeholders and this increase agricultural production and agribusiness.
Cultural Aspects of Business‐to‐Consumer (B2C) E‐commerce: Acomparative Analysis of Pakistan and Australia
Authors: Sohaib Osama , Kang Kyeong
Published: December 2017

It is generally believed that Business to‐Consumer (B2C) e‐commerce will help firms to improve productivity to the global market both in developing and developed countries. This study examines the extent of B2C websites communication differentiation on cultural ground. Through a content analysis, Hofstede's and Hall's cultural factors were examined in 64 B2C e‐commerce websites of Pakistan and Australia. To test for the difference an independent samples t‐test was conducted. The results show that B2C websites somehow reflects the cultural environment that surrounds the online buyers. It appears that to influence online buyers to purchase, firms need to develop culturally adapted websites. This study provides some indications that the cultural trend in B2C websites is providing opportunities to business firms to make changes to their market strategies to better trigger their online sale by targeting two different cultures.
