A Citational Analysis of the Accounting Information Network

Citations appended to journal articles give us a measure of the number of formal messages passed between knowledge systems. They also provide a possible index for measuring the influence of one knowledge system on another. The accounting knowledge system nests within the social science knowledge system and is itself composed of at least three subsystems: an academic system, a management accounting system, and a professional system. An important component of each of these knowledge subsystems is the set of various journals which collect, store, and distribute information to their readers. Figure 1 presents a graphical description of the various component parts of the accounting knowledge system. In this paper, I examine first the flow of messages between the accounting system and other knowledge systems, and then the flow of messages within the accounting knowledge system, paying particular attention to the information flow between the academic and applied accounting networks. This will be followed by a citational profile of certain accounting journals. It should be emphasized that no qualitative connotation is implied by the analysis. The article provides an inventory of information flow within the accounting journal network.
A statistical model of fatigue failure incorporating effects of specimen size and load amplitude on fatigue life

ABSTRACT Among many contributing factors, the load range, number of load cycles and specimen geometry (including configuration and size) are three major variables for fatigue failure. Most existing statistical fatigue models deal with only one or two of these three variables. According to the statistical distribution of microcracks with respect to their size and spatial location, a weakest-link probabilistic model for fatigue failure is established to incorporate the combined effect of load range, number of load cycles and specimen size. The model reveals a compound parameter of load range and number of load cycles reminiscent of the empirical formulae of fatigue stress-life curve and its correlation with another compound parameter of cumulative failure probability and specimen size. Four sets of published fatigue test data are adopted to validate the model.
A 93.5% efficiency, 400-mA current-mode dc-dc buck converter with watchdog functions

A current-mode dc-dc buck converter was implemented in a standard 0.35- m 1-poly 6-metal 3.3-V CMOS technology. This paper proposes watchdog circuits in order to ensure the reliability and to improve the performance of dc-dc converters. The dc-dc converter systems can be protected from over-voltage, over-temperature, and over-current conditions. In addition to the protection from destructive conditions, a reversecurrent protection circuit is implemented to improve efficiency under light-load conditions. The maximum efficiency of the fabricated converter was 93.5%. The chip area is only 1.02 mm2.
Hyperthermia-Induced Cardioprotection Is Potentiated by Ischemic Postconditioning in Rats

We tested the hypothesis that the protective effects of hyperthermia (HT) could be augmented by ischemic postconditioning (PostC) via enhancement of reperfusion-induced Akt phosphorylation. The role of the mitoKATP channel as an effecter to protect hearts against ischemia/reperfusion injury was also investigated. In isolated perfused heart experiments using a Langendorff apparatus, 30 min of no-flow global ischemia was followed by 120 min of reperfusion. Ischemic PostC, 5 cycles of 10-sec reperfusion/10-sec ischemia, was achieved at the initial moment of reperfusion. Hyperthermia (HT, 43°C for 20 min) was applied 24 hr before ischemia onset. Ischemic PostC alone did not show significant protection, but HT did. The HT-induced protection in terms of infarct size, recovery of left ventricular performance, amount of released creatine kinase and apoptosis were enhanced by ischemic PostC. These protective effects were consistent with the levels of Akt phosphorylation 7 min after reperfusion and were completely blocked by the pretreatment with the phosphatidylinositol 3-kinase inhibitor wortmannin. HT-induced protection was also completely abolished by concomitant perfusion with 5-hydroxydecanoate (5HD, 100 μM), an inhibitor of the mitochondrial ATP-sensitive potassium (mitoKATP) channel. However, the potentiated protection by ischemic PostC remained, even in the presence of 5HD. In conclusion, ischemic PostC could potentiate the protective effects of HT possibly via enhancement of reperfusion-induced Akt phosphorylation. Although the opening of the mitoKATP channel is predominantly involved as an effecter in HT-induced protection, potentiated protection by ischemic PostC may involve mechanisms other than the mitoKATP channel.
The intraductal pancreatic pressure in chronic obstructive pancreatitis.

During operations for chronic obstructive pancreatitis in seven men the intraductal pressure was measured after puncture of the dilated pancreatic duct. The median pressure was 26 mm Hg (range, 20–42 mm Hg). The increased pressures indicate that the dilatation is secondary to the obstruction of the pancreatic duct, demonstrated by pancreatography.
Population‐based case‐control teratologic study of topical miconazole

ABSTRACT Miconazole cream is used in Hungary to treat fungal genital and skin infections in pregnant women, but it causes anxiety for both patients and medical doctors due to the category C classification of the drug regarding teratogenic or fetotoxic risk. The objective of this case–control study was to analyze the teratogenic potential of topical miconazole used during pregnancy in the mothers of babies with congenital abnormalities and in matched control mothers of babies without congenital abnormalities. The population‐based data set of the Hungarian Case–Control Surveillance of Congenital Abnormalities between 1980 and 1996 included 22 843 women who had newborns or fetuses with congenital abnormalities, and 38 151 pregnant women who had newborn infants without any defects (controls). In the case group, 24 (0.11%) and in the control group, 46 (0.12%) pregnant women were treated with miconazole (crude odd ratio [OR]: 0.9 with 95% confidence interval [CI]: 0.6–1.6). Different congenital abnormality groups were evaluated in case–control pairs and a higher prevalence of miconazole treatment was not found during the second or third month of pregnancy. Thus, treatment with topical miconazole during pregnancy does not increase the risk of congenital abnormalities.
High performance reflectors for telecom space antennas in MELCO

High performance reflectors for telecom space such as, ultra light weight membrane reflectors, ka-band dual gridded antennas and high precision steerable antennas, are presented. Ultra light weight membrane reflectors can save the weight by more than 50% of conventional honeycomb. Large reflectors up to 3.2m have been in a commercial flight and their stable performances have been proven on orbit. A ka-band highly shaped dual gridded antenna for both transmit and receive use has been demonstrated for broadband satellite communication, and its low thermal distortion characteristics have been confirmed. A beam steering antenna is also presented which is steerable to any position on the earth disk for providing communication service flexibility to high traffic regions. Measured performances are in good agreement with the designed and its functions and stability have been proven on orbit.
Retrospective investigation of testosterone undecanoate depot for the long-term treatment of male hypogonadism in clinical practice.

INTRODUCTION Testosterone undecanoate depot (TUD) administered intramuscularly is an effective form of testosterone replacement therapy (TRT) for male hypogonadism. Because of the ease of administration, TUD therapy may be preferable to subcutaneously implanted extended release T pellet implants (TI). AIM The primary objective was to retrospectively assess the efficacy and safety of long-term (≥ 2 years therapy) TUD therapy in the clinical setting. The secondary objective was to retrospectively compare TUD with TI therapy. METHODS Retrospective data were collected from the Waikato Hospital Endocrine Database for 179 hypogonadal men treated with TUD for ≥ 2 years from 1998-2011, with 124 of these men receiving previous TI therapy. MAIN OUTCOME MEASURES The main outcome measure for efficacy was serum trough total testosterone (TT), and for safety an increase in hemoglobin (Hb) and/or hematocrit (Hct), rise in prostate-specific antigen (PSA) and/or prostatic biopsy and alteration in body mass index and lipid profile. Additional outcome measures were changes in the dosing and/or interval regimens for TUD therapy. RESULTS Overall, 72% of trough TT levels were in the normal range for TUD therapy compared with 53% of trough TT levels during TI therapy. TUD therapy was well tolerated with 162 men (90.5%) completing 2 years of treatment, and only seven men (3.9%) stopping TUD because of adverse effects. A rise in Hb and/or Hct occurred in 25 men (14%), and a significant rise in PSA in 20 men (13%) at some stage during TUD therapy. At 2 years, 91% of men received the standard 1,000 mg TUD dose with 66% at the standard dosing interval of 10-14 weekly. CONCLUSIONS TUD is an efficacious, safe, and well tolerated form of TRT, and individual optimisation of the dose and/or interval is only required in the minority of men. Particularly given the ease of administration, TUD was the preferred TRT for both patients and clinicians.
Impact of assessment of bone status before corrective surgery of lumbar spine in patients over 50 years old

Background and objective: There is absence of data on the prevalence of osteoporosis before corrective surgery of the lumbar spine. We do not know the impact of bone assessment before corrective spine surgery, regarding the prevalence of osteoporosis, risk factors for osteoporosis, and prescription of osteoporotic treatment. Our objective was to evaluate the impact of assessment of bone status before corrective surgery of the lumbar spine. Methods: This retrospective study was conducted over a period of 30 months. Patients included were over 50 years old and had been referred to rheumatology consultation prior to corrective surgery of the lumbar spine with osteosynthesis, for scoliosis or spondylolisthesis. Assessment of bone status consisted in looking for risk factors for osteoporotic fracture, performing bone densitometry with the calculation of TBS (trabecular bone score) and the possible introduction of treatment for osteoporosis. Data were collected on complications related to bone fragility during follow-up. Results: Twenty-eight patients with a median age of 71.2 years (55.5–84.8) were included; 89% were women. T score was <−2.5 in 14.3% (4/28) and −1 to −2.5 in 42.9% (12/28) on at least one of the three sites analyzed. Fifty percent of patients had a TBS <1.2, a history of more than four falls per year, a duration of more than 20 s in the Timed Up and Go Test, and/or sedation treatment. Vitamin-calcium supplementation and treatment for osteoporosis were prescribed in 71.4% and 17.8% of cases, respectively. During follow-up, 3 patients had one or more osteoporotic vertebral fractures and 4 patients had loosening of implanted devices. Conclusion: Despite a low prevalence of densitometric osteoporosis and therapeutic management, one in four patients had a bone complication, suggesting the superiority of TBS as an indicator of bone status.
Effect of hepatitis C virus infection on the risk of non‐Hodgkin's lymphoma: A meta‐analysis of epidemiological studies

Although a high prevalence of hepatitis C virus (HCV) infection among non‐Hodgkin's lymphoma (NHL) patients had been reported, subsequent epidemiological studies conducted to examine a causal association between HCV and NHL have provided inconsistent results across studies. A strikingly positive association has been reported primarily from Italy and Japan, while no association was found in other regions of the world. To clarify the association between HCV and NHL, we conducted a systematic literature review. Eligible study designs were nested case‐control studies, population‐based case‐control studies, and hospital‐based case‐control studies using non‐cancer subjects as controls. The studies published through January 1991 to August 2003 were searched through Medline. Ultimately, 23 studies with 4049 NHL patients and 1,813,480 controls were identified. Summary statistics were crude odds ratios (ORs) comparing the anti‐HCV se‐ropositive and seronegative subjects. As we identified heterogeneity between studies, summary statistics were calculated based on a random‐effect model. We did not find any evidence of publication bias. The major sources of variation were the use of blood donor controls and year of publication. The summary OR for NHL was 5.70 (95% confidence interval (Cl), 4.09–7.96, P<0.001). The subgroup analysis by phenotype showed a similar trend for B‐cell (5.04, 95% Cl: 3.59–7.06) and T‐NHL (2.51, 95% Cl: 1.39–4.56). In conclusion, we found a strongly positive association between anti‐HCV seropositive test subjects and risk of NHL. Further biological studies examining this association are warranted.
Quality Expectations, Reputation, and Price

The impact on price of current product quality and reputation are estimated using data from the market for Bordeaux wine. A model is proposed in which price is a function of current quality and expected quality, where the latter depends on reputation. Equations determining price and expected quality are estimated jointly. The empirical findings show that the price premium associated with better individual and collective (or group) reputation far exceeds that associated with improvements in current quality. As well, the market values collective reputation indicators only to the extent that they are useful predictors of product quality.
Le diabète sucré en Afrique subsaharienne : aspects épidémiologiques, difficultés de prise en charge.

Contrairement a une vieille opinion considerant le diabete sucre comme une maladie des pays riches, cette affection constitue de plus en plus une preoccupation majeure dans les pays en developpement et particulierement en Afrique subsaharienne. On note une croissance galopante de sa prevalence alors que parallelement les structures sanitaires n'ont pas connu un developpement adapte. L'OMS prevoit une croissance mondiale de la prevalence du diabete, qui devrait atteindre 300 millions de malades en 2025. Cette evolution est plus nette dans les pays en developpement, et particulierement en Afrique subsaharienne. Dans ces pays, cette expansion s'inscrit dans une veritable transition epidemiologique des maladies transmissibles vers les maladies non transmissibles. Ce phenomene reconnait plusieurs causes dont le vieillissement de la population, la sedentarite et l'obesite. En dehors de l'obesite, l'hypertension arterielle est le principal facteur de risque cardio-vasculaire associe au diabete. Seul ou associe aux autres facteurs de risque, le diabete sucre est responsable d'une lourde morbidite notamment cardio-vasculaire et renale. La prise en charge connait de nombreuses difficultes : une meconnaissance de l'ampleur du probleme, le cout des medicaments, un contexte socio-economique peu propice au regime diabetique, des infrastructures et du personnel sanitaires insuffisants. La croissance rapide de la prevalence du diabete sucre en Afrique subsaharienne constitue une menace. Il est urgent de proceder a une evaluation chiffree de la pandemie diabetique, permettant la formation en nombre consequent de personnels sanitaires qualifies, et l'acquisition d'un equipement suffisant pour une prise en charge decentralisee. Ces conditions appellent la sensibilisation et la participation de tous les acteurs intervenant dans la sante publique.
Determination of efficient environmental policy instruments under uncertainty with the dominant firm model

This paper reveals what the optimal environmental policy instruments under uncertainty are when there is one mighty (dominant) firm in a group of firms that produce homogeneous products. We extend and improve the research findings of Weitzman (1974). A dominant firm affects the decision making of other fringe firms. In this paper, we look at a case where a regulator implements environmental policy instruments, such as taxes or a quota, by focusing predominantly on the dominant firm. This paper estimates efficient policy by examining the deadweight loss caused by integrating the marginal abatement cost (MAC) to the marginal damage (MD). We set two parameters to measure the slope of the MD and that of the MAC for the fringe firms against that of the MAC for the dominant firm. This is done to estimate efficient policy and its preconditions. Consequently, the regulation adversely impacts each firm in the dominant firm model. Tax regulation is superior to the implementation of a quota when the slope of the MAC is equal to that of the MD, whereas the two policies have the same effect under the same conditions in the study by Weitzman (1974). Additionally, a quota policy is preferred when the MAC for the fringe firms is flatter than that of the dominant firm in contrast to the study by Weitzman (1974).
Selecting Weight Functions to Spur Competition in Quasi-Proportional Auctions

In quasi-proportional auctions, each bidder receives a fraction of the allocation equal to the weight of his bid divided by the sum of the weights of all bids, where a bid's weight is determined by a chosen weight function. We study the relationship between the weight function, bidders' private values, and the auctioneer's revenue in equilibrium. It has been shown that if one bidder has a much higher private value than the others, then the revenue-optimizing weight function is nearly flat. Essentially, threatening the bidder with the highest valuation to share the allocation of the rewards maximizes the auctioneer's revenue. We show that as bidder private values approach parity, the revenue-maximizing weight function becomes steeper, making the quasi-proportional auction more like a winner-take-all auction. For flatter weight functions, there is known to be a unique pure-strategy Nash equilibrium. We show that this also holds for steeper weight functions, at least in the two-bidder case. We also give some analysis and intuition about why this may hold for more bidders.
An exploration of addiction in adults experiencing early-life stress: a metasynthesis 1

ABSTRACT Objective: to review and synthesize qualitative research on the links between early-life stress and addiction behaviours in adulthood. Method: metasynthesis to review qualitative research findings based on procedures that outline how to identify themes or constructs across studies in a specific area. Comprehensive searches of multiple electronic databases were performed. The initial search yielded 1050 articles and the titles and abstracts were screened for inclusion based on predetermined criteria. Thirty-eight full text, peer-reviewed articles were retrieved and assessed by three independent reviewers. Twelve articles were eligible for full review and appraised using the Critical Appraisal Skills Programme (CASP) tools. Results: the findings revealed that clear associations exist between early-life stress and addictive behaviours in adulthood, such as between trauma in childhood, violence, and addictive behaviours. A common theme in the findings indicates that participants turn to addictive substances as a way of strategically coping with stressful childhood experiences, regardless of the harmful side effects or detrimental social outcomes. Conclusion: it can be inferred that addiction may be viewed as a way to deal with adversity in childhood and that there is an interrelationship between addiction, domestic violence and crime.
Mobility Modes Awareness from Trajectories Based on Clustering and a Convolutional Neural Network

Massive trajectory data generated by ubiquitous position acquisition technology are valuable for knowledge discovery. The study of trajectory mining that converts knowledge into decision support becomes appealing. Mobility modes awareness is one of the most important aspects of trajectory mining. It contributes to land use planning, intelligent transportation, anomaly events prevention, etc. To achieve better comprehension of mobility modes, we propose a method to integrate the issues of mobility modes discovery and mobility modes identification together. Firstly, route patterns of trajectories were mined based on unsupervised origin and destination (OD) points clustering. After the combination of route patterns and travel activity information, different mobility modes existing in history trajectories were discovered. Then a convolutional neural network (CNN)-based method was proposed to identify the mobility modes of newly emerging trajectories. The labeled history trajectory data were utilized to train the identification model. Moreover, in this approach, we introduced a mobility-based trajectory structure as the input of the identification model. This method was evaluated with a real-world maritime trajectory dataset. The experiment results indicated the excellence of this method. The mobility modes discovered by our method were clearly distinguishable from each other and the identification accuracy was higher compared with other techniques.
Spontaneous intracranial hypotension: a cause of severe acute headache

Severe acute headache is a common presenting symptom to an accident and emergency department. Spontaneous intracranial hypotension (SIH) is an increasingly recognised cause of these symptoms and has characteristic clinical and imaging findings. SIH is characterised by headache worse on standing, low opening cerebrospinal fluid pressures at lumbar puncture and uniform pachymeningeal enhancement with gadolinium enhanced magnetic resonance imaging of the brain, all in the absence of dural trauma. Atypical presentations occur and severe neurological decline can rarely be associated with this condition. A review of five patients presenting recently to our institution with classical imaging findings together with a review of the literature is presented.
Breast-milk fat concentrations of rural African women

1. Detailed studies of variations in breast-milk fat concentrations were performed over 12 or 24 h periods on sixty rural Gambian women feeding on demand. The creamatocrit method (Lucas et al. 1978) was used. 2. The complex pattern of within-feed and between-feed changes in fat concentration was largely explained by differences in volume per feed and time interval between feeds. 3. No consistent difference in fat production between the breasts of each individual was found despite the local custom of starting all feeds on the right breast. 4. A marked diurnal variation in the mean fat concentration per feed was noted. On average the highest values occurred in the early morning, the lowest values in the late afternoon. 5. There was significantly greater between-individual than within-individual variation in the mean fat concentration per feed over 12 h (P > 0.001). 6. A simple, rational and non-intrusive sampling procedure was devised for the estimation of whole-day mean fat levels based on the finding that the mean fat concentration of small samples of milk (0.25 ml) taken from both breasts before and after one specific feed of the day was closely correlated with 12 h and 24 h mean fat concentrations.
