Improving entrepreneurial opportunity recognition through web content analytics

The ability to recognize and develop an opportunity into a venture defines an entrepreneur. Research in opportunity recognition has been robust and focuses more on explaining the processes involved in opportunity recognition. Factors such as prior knowledge, cognitive and creative capabilities are shown to affect opportunity recognition in entrepreneurs. Prior knowledge in areas such as customer problems, ways to serve the market, and technology has been shows in various studies to be a factor that facilitates entrepreneurs to identify and recognize opportunities. Findings from research also shows that experienced entrepreneurs search and scan for information to discover opportunities. Searching and scanning for information has also been shown to help novice entrepreneurs who lack prior knowledge to narrow this gap and enable them to better identify and recognize opportunities. There is less focus in research on finding empirically proven techniques and methods to develop and enhance opportunity recogniti.
Influence of a three-day feed and water deprivation period on gut fill, tissue weights, and tissue composition in mature wethers.

Fourteen mature wethers (average BW 71.8 +/- .86 kg) were used to study the effects of feed and water deprivation on the quantity and composition of gastrointestinal tract (GIT) contents and tissues. Sheep (seven/treatment) were randomly assigned to one of two treatments: 1) limit fed 1,400 g/d of a pelleted diet or 2) deprived of feed and water for 3 d. Before euthanasia, sheep were infused i.v. with Evans blue, sodium thiocyanate, and antipyrine to determine plasma, extracellular, and total body water, respectively. Blood samples were obtained for 4 h after the infusions. Sheep were killed by injection of a lethal dose of a general anesthetic and organs were immediately removed, weighed, and sampled. Compared with controls, unfed sheep lost 7.1 kg (9.9%; P < .05) of their BW during the 3-d deprivation period, of which 21.1% was from the stomach contents, 28.1% (P < .05) was from the GIT (stomach + intestine) contents, and 6.7% (P < .02) was from GIT tissues. The weight loss of the liver, lungs, heart, and kidneys each accounted for less than 1% of the total weight loss. Of the total weight loss, 80% (P < .09) was body water. Of total body water loss, 57% (P < .20) was from the intracellular compartment and 29% (P < .06) was from the GIT contents. Total Ca, Na, Mg, Cu, Fe, and Zn losses via fecal + urinary excretion were less or equal to losses from the GIT contents. (ABSTRACT TRUNCATED AT 250 WORDS)
Entrepreneurial Orientation for Sustainable Competitive Advantage and Risk Management: Evidence from Government-Linked Companies in Malaysia

This study is an attempt to assess the status of the current level of entrepreneurial orientation among the Government-Linked Companies (GLCs) in Malaysia. This study collected primary data based on a set of questionnaire survey among 134 executives and managers of GLCs in Malaysia. The data were collected based on opinions of the seven factors of entrepreneurial orientation practices by using the five-point Likert scale. The data were analysed using descriptive statistics. Further, the reliability of the data was tested using Cronbach’s alpha test, the validity of the data was tested by checking the normality test through skewness and kurtosis, and the consistency of the data was tested using factor analysis. On an average, 70.9% of the respondents agreed that they focus on these factors of entrepreneurial orientation. The federal owned GLCs place more emphasis on entrepreneurial orientation than the state owned GLCs. This study suggests improving the practices of entrepreneurial orientation of GLCs in Malaysia by emphasizing on recognizing individual risk takers for their willingness to champion new projects, whether it eventually turns out to be successful or not, encouraging employees to take calculated risks with new ideas, considering the term “risk taker” as a positive attribute for people in the organization, and supporting many small and experimental projects by realizing that some will undoubtedly fail.
Country and regional carbon stock in forest cover – estimates based on the first cycle of the Czech National Forest Inventory data (2001–2004)

Abstract Since forests can play an efficient role in the mitigation of greenhouse gas emissions, objective information about the actual carbon stock is very important. Therefore, the presented paper analysed the carbon stock in the living merchantable trees (with diameter at breast height above 7 cm) of the Czech forests with regard to groups of tree species and tree compartments (wood under bark with diameter above 7 cm, wood under bark with diameter below 7 cm, bark, green twigs, foliage, stump and roots). We examined its regional distribution and relationship to the number of inhabitants and the gross domestic product. The data used for the analysis originated from 13,929 forest plots of the first Czech National Forest Inventory performed between 2001 and 2004. The total tree carbon stock was obtained as a sum of the carbon stock in the individual tree compartments estimated from the biomass amount in the compartments multiplied by the relative carbon content. Wood biomass amount was calculated by multiplying a particular part of tree volume with species-specific green wood density. The total amount of carbon stored in forest trees in the Czech Republic was over 327 mill. t, which is about 113 t of carbon per ha of forests. The highest carbon amount (160 mill. t, i.e. 49.0% of the total amount) was fixed in spruce. The minimum carbon amount fixed in the forest cover (14.35 mill. t) was calculated for Ústecký kraj (region), while the maximum carbon amount (51.51 mill. t) was found in Jihočeský kraj.
Analyst Forecast Bundling

Changing economic conditions over the past two decades have created incentives for sell-side analysts to both provide their institutional clients tiered services and to streamline their written research process. One manifestation of these changes is an increased likelihood of analysts’ issuing earnings forecasts for multiple firms on the same day. We identify this bundling property and show that bundling has increased steadily over time. We provide field evidence that the practice is a cost-saving measure, a natural by-product of analysts focusing on thematic research, and a reflection of forecast updating that occurs in advance of important events. Our empirical analyses show that bundled forecasts are less accurate, less bold, and less informative to investors than nonbundled forecasts. We also find that analysts who produce bundled forecasts provide valuable specialized services to their institutional clients. Our findings ultimately demonstrate that forecast bundling has important implications for the properties of analysts’ forecasts.This paper was accepted by Shiva Rajgopal, accounting.
Post-Entry On-going Organizational Changes in Core Activities of Foreign Subsidiaries and Firm Survival

By applying conventional organizational adaptation theory, this study explores the relationship between post-entry on-going organizational changes in core areas of foreign subsidiaries, such as investment amount, ownership, and product, and the subsequent survival of such subsidiaries in a host country. This study further investigates the relative importance of subsidiary’s organizational change in core areas. For these research questions, this study employs a sample of 2,582 foreign direct investment cases by Korean textile firms. The findings show that a foreign subsidiary’s post-entry ongoing organizational changes in the core areas are negatively associated with its mortality rate. However, we carefully qualify this result: ongoing changes in investment amount and product areas help reduce the mortality rate, whereas changes in ownership do not.
The Influence of E-Customer Services and Perceived Value on Brand Loyalty of Banks and Internet Banking Adoption: A Structural Equation Model (SEM)

There is a plethora of research which has dealt with service quality issues in different service organization. Therefore, very little research has been done on electronic service quality. The objective of this research is to measure the E-customer service that is the core dimension of e-service quality with internet banking adoption and Brand loyalty of Banks. In addition to this Customer perceived value has also been explored within internet banking context. A self-administered survey was conducted to approach 500 internet banking users in major cities of Pakistan. The data was analyzed through performing various quantitative measures such as correlation and structural equation model (SEM) by using AMOS. Findings reveal that e-customer service and perceived value significantly influence on internet banking adoption and brand loyalty of Banks. This research is first in its nature that reveals the influence of e-customer service on internet banking adoption and enriches the e-service quality literature.
Conversion of Aβ43 to Aβ40 by the successive action of angiotensin‐converting enzyme 2 and angiotensin‐converting enzyme

The longer and neurotoxic species of amyloid‐β protein (Aβ), Aβ42 and Aβ43, contribute to Aβ accumulation in Alzheimer's disease (AD) pathogenesis and are considered to be the primary cause of the disease. In contrast, the predominant secreted form of Aβ, Aβ40, inhibits amyloid deposition and may have neuroprotective effects. We have reported that angiotensin‐converting enzyme (ACE) converts Aβ42 to Aβ40 and that Aβ43 is the earliest‐depositing Aβ species in the amyloid precursor protein transgenic mouse brain. Here we found that Aβ43 can be converted to Aβ42 and to Aβ40 in mouse brain lysate. We further identified the brain Aβ43‐to‐Aβ42‐converting enzyme as ACE2. The purified human ACE2 converted Aβ43 to Aβ42, and this activity was inhibited by a specific ACE2 inhibitor, DX600. Notably, the combination of ACE2 and ACE could convert Aβ43 to Aβ40. Our results indicate that the longer, neurotoxic forms of Aβ can be converted to the shorter, less toxic or neuroprotective forms of Aβ by ACE2 and ACE. Moreover, we found that ACE2 activity showed a tendency to decrease in the serum of AD patients compared with normal controls, suggesting an association between lower ACE2 activity and AD. Thus, maintaining brain ACE2 and ACE activities may be important for preventing brain amyloid neurotoxicity and deposition in Alzheimer's disease. © 2014 Wiley Periodicals, Inc.
Work organisation and employee involvement in Europe

There were marked differences between countries in the control that employees can exercise over their work tasks, their involvement in wider organisational decision-making and the likelihood that they work in a high involvement organisation. The Nordic countries (Denmark, Finland and Sweden) had the highest levels of involvement, while the Southern countries (Greece, Italy, Portugal and Spain) and the EastSouth countries (Bulgaria and Romania) had particularly low levels of involvement. The high levels of involvement in Nordic workplaces are evident even when a wide range of factors relating to individual characteristics and economic structures are controlled for. This suggests that it is influenced by a distinctive policy environment.
Concordant evolutionary patterns among Indo-West Pacific Butterflyfishes

Genetic differences within a 495 base pair section of the mitochondrial cytochrome b gene reveal a striking concordance among species in two monophyletic groups of Indo-west Pacific butterflyfishes. In both species groups, an approximately 2.0% genetic break clearly partitions individuals between the Indian Ocean and Pacific Ocean. However, levels of intra-Pacific mtDNA variation are low, on average less than 1.0%, and fail to cluster by species boundaries defined by colour pattern. Individuals from different species, separated by thousands of kilometers, often possess identical cytochrome b sequences, whereas conspecifics from the same reefs can show up to 1.5% difference. The discrepancy between the mtDNA gene tree and species boundaries may reflect retained ancestral variation or may be the result of hybridization. The strong temporal and phylogenetic concordance between these two independent species groups suggests that genetic differentiation was influenced by common environmental factors. Low levels of within- and between-species genetic differences imply a recent divergence time and suggest a link between speciation within each group and Pleistocene climatic fluctuations. These results paint a turbulent picture of the recent evolutionary history of the Indo-West Pacific.
FDG Uptake in Non–Small Cell Lung Cancer Is Not an Independent Predictor of EGFR or KRAS Mutation Status: A Retrospective Analysis of 206 Patients

Purpose Data in the literature regarding the use of 18F-FDG avidity of non–small cell lung cancer (NSCLC) as an imaging biomarker to predict the status of epidermal growth factor receptor (EGFR) mutation are conflicting. Association between KRAS mutation and FDG avidity of NSCLC on PET/CT is not well known. We assessed whether the EGFR or KRAS mutation status in NSCLC can be predicted by FDG avidity by performing several different subgroup analyses to better compare with various published results. Patients and Methods After obtaining institutional review board approval, we enrolled patients (1) who had FDG PET/CT performed for staging of NSCLC, (2) with EGFR and KRAS mutational status of tumor identified, and (3) without uncontrolled diabetes. Univariate and multivariate regression analyses were performed to assess the relationship between the independent clinical variables (sex, age, smoking history, tumor histology, tumor size, stage, and SUV-derived variables) and the EGFR and KRAS mutation status. Separate analyses were performed for patients with adenocarcinomas. Results There were 206 patients (age, 33–88 years; 148 male/58 female; 71 ever-smokers/135 never-smokers; 135 adenocarcinoma/71 squamous cell carcinoma; 22 stage I-II/184 stage III-IV; tumor size, 1.2–15.0 cm; SUVmax, 2.9–36.4; EGFR mutations present in 47; KRAS mutations present in 20). In multivariate analysis, sex, smoking history, histology, and tumor size were significantly associated with EGFR mutation but none of the SUV-derived variables was. Likewise, no correlation was found between the SUV-derived variables and KRAS mutation. Conclusions Our results suggest that FDG avidity of NSCLC has no significant clinical value in predicting the EGFR or KRAS mutation status.
Lipocalin 2: A multifaceted modulator of human cancer

Lipocalin 2 (Lcn2), a member of the lipocalin family that carries small lipophilic ligands, has gained recent attention as both a potential biomarker and a modulator of human cancers. Here we describe recent findings of the functions of Lcn2 in breast cancer and the potential mechanisms that underlie its actions. Lcn2 has been shown to induce the epithelial to mesenchymal transition (EMT) in breast cancer cells and to promote breast tumor invasion. Estrogen receptor α may participate in the pathway that leads to Lcn2-induced EMT. Preliminary evidence also suggests that Lcn2 may be used as a potential non-invasive urinary biomarker of breast cancer. Elevated levels of Lcn2 have also been reported in other human cancers. The potential roles of Lcn2 in some other epithelial tumors as well as leukemia are also reviewed and discussed here.
Comparison of Blood Gas and Acid-Base Measurements in Arterial and Venous Blood Samples in Patients with Uremic Acidosis and Diabetic Ketoacidosis in the Emergency Room

Background/aims: The aim of this study was to examine a plausible correlation between venous and arterial blood gas values in acidotic patients with chronic uremia or diabetic ketoacidosis (DKA). Methods: A total of 152 arterial and 152 venous blood samples from uremic patients (n = 100), DKA patients (n = 21) and healthy controls (n = 31) were analyzed for measurements of blood gas and acid-base status. Results: The means of arterial and venous pH, and arterial and venous HCO<sup>–</sup><sub>3</sub> values for the uremic patients were 7.17 ± 0.14, 7.13 ± 0.14, 10.13 ± 4.26 and 11.86 ± 4.23 mmol/l, respectively. The respective mean differences between arterial and venous pH values and arterial and venous HCO<sup>–</sup><sub>3</sub> values were 0.04 ± 0.02 and –1.72 ± 0.42 mmol/l, respectively, for these patients. The means of the laboratory findings of DKA patients were arterial pH, 7.15 ± 0.15; venous pH, 7.10 ± 0.15; arterial HCO<sup>–</sup><sub>3</sub>, 8.57 ± 5.71 mmol/l and venous HCO<sup>–</sup><sub>3</sub>, 10.46 ± 5.73 mmol/l. The respective mean differences between arterial and venous pH and arterial and venous HCO<sup>–</sup><sub>3</sub> for this group were calculated to be 0.05 ± 0.01 and –1.88 ± 0.41 mmol/l. In the healthy controls, the means of arterial and venous pH, and arterial and venous HCO<sup>–</sup><sub>3</sub> values were 7.39 ± 0.02, 7.34 ± 0.02, 24.91 ± 0.82 and 26.57 ± 0.83 mmol/l, respectively. For the healthy controls the mean differences between the respective values in arterial and venous pH, and arterial and venous HCO<sup>–</sup><sub>3</sub> were 0.05 ± 0.01 and –1.66 ± 0.58 mmol/l. Although in healthy controls the correlation between arterial and venous pH values (r<sup>2</sup>: 0.595) and arterial and venous HCO<sup>–</sup><sub>3</sub> values (r<sup>2</sup>: 0.552) were moderate, these correlations were significantly increased in both the acidotic patient group (r<sup>2</sup>: 0.979 and 0.990) and the DKA group (r<sup>2</sup>: 0.989 and 0.995) Conclusion: A venous blood sample can be used to evaluate the acid-base status in uremic and DKA patients.
An Exploratory Study on the Determinants of Purchase Intention for Internet of Things Products

AN EXPLORATORY STUDY ON THE DETERMINANTS OF PURCHASE INTETNION FOR INTERNET OF THINGS PRODUCTS by Margaret Holman, 2017 Department of Strategic Communication Texas Christian University Thesis Advisor: Joshua Bentley, Assistant Professor of Strategic Communication Julie O’Neil, Associate Professor of Strategic Communication and Director of Graduate Studies Jong-Hyuok Jung, Assistant Professor of Strategic Communication The purpose of this study was to explore factors that influence customer’s intentions to purchase Internet of Things (IoT) technologies. Intended as an exploratory study to expand on technology acceptance variables, this study tested the effects of brand trust, performance expectancy, effort expectancy, social influence, self-efficacy, anxiety, and privacy concerns on purchase intention for IoT products. Using three surveys, the researcher found that performance expectancy had a positive effect on purchase intention. Anxiety had a negative effect on purchase intention, while privacy concerns, social influence and self-efficacy were not significant. Brand trust and effort expectancy had varying influences on purchase intention depending on whether the participant was responding to an advertisement for a product with high brand trust or low brand trust. This study has implications for what issues companies should address or avoid in their marketing communication to increase adoption of IoT products.
Cultivating Teacher Mindfulness: Effects of a Randomized Controlled Trial on Work, Home, and Sleep Outcomes

The effects of randomization to a workplace mindfulness training (WMT) or a waitlist control condition on teachers’ well-being (moods and satisfaction at work and home), quantity of sleep, quality of sleep, and sleepiness during the day were examined in 2 randomized, waitlist controlled trials (RCTs). The combined sample of the 2 RCTs, conducted in Canada and the United States, included 113 elementary and secondary school teachers (89% female). Measures were collected at baseline, postprogram, and 3-month follow-up; teachers were randomly assigned to condition after baseline assessment. Results showed that teachers randomized to WMT reported less frequent bad moods at work and home, greater satisfaction at work and home, more sleep on weekday nights, better quality sleep, and decreased insomnia symptoms and daytime sleepiness. Training-related group differences in mindfulness and rumination on work at home at postprogram partially mediated the reductions in negative moods at home and increases in sleep quality at follow-up.

Determining measures of insight and foresight from responses to multiple choice questions

Background: Clinical decisions require insight and foresight. When these are lacking, overconfidence and error can occur. Aims: Multiple choice questions (MCQ) responses were used to estimate insight, as determined by confidence in responses, and foresight, as determined by the safety of incorrect responses. Methods: An MCQ response system was developed which reflected confidence in, and safeness of, responses. An optional examination incorporating this system was offered to medical students at one university. Results: A total of 372 students completed the study. There was evidence of insight. The proportion of responses that were correct rose from 32% for low confidence to 77% for high confidence. The proportion that was incorrect and not unsafe fell from 34% for low confidence to 7% for high confidence. There was less evidence of foresight. Of the responses that were incorrect, the proportion that was unsafe increased from 52% for low confidence to 68% for high confidence. Measures of insight and foresight increased with experience. Students with poorer knowledge chose more unsafe responses, but with lower confidence. Five students gave multiple highly unsafe responses held with high confidence. Conclusions: Students had insight but less foresight. Experience and knowledge altered measures of both. This response system identified students who appeared to lack both.
