Emotion in enterprise social media systems
Authors: Reychav Iris , Inbar Ofer , Simon Tomer , McHaney Roger , Zhu Lin 
Published: January 2019

PurposeThe purpose of this paper is to investigate enterprise social media systems and quantified gender and status influences on emotional content presented in these systems.Design/methodology/approachInternal social media messages were collected from a global software company running an enterprise social media system. An indirect observatory test using Berlo’s “source–message–channel–receiver” model served as a framework to evaluate sender, message, channel and receiver for each text. These texts were categorized by gender and status using text analytics with SAP SA to produce sentiment indications.FindingsResults reveal women use positive language 2.1 times more than men. Senior managers express positive language 1.7 times more than non-managers, and feeling rules affect all genders and statuses, but not necessarily as predicted by theory. Other findings show that public messages contained less emotional content, and women expressed more positivity to lower status colleagues. Men expressed more positivity to those in higher positions. Many gender and status stereotypes found in face-to-face studies are also present in digital enterprise social networks.Research limitations/implicationsLimitations include generalizability: all data were collected from a single enterprise social media system.Practical implicationsManagers establishing codes of conduct for social media use will find this research useful, particularly when promoting awareness of emotional expressiveness in online venues with subordinate colleagues.Originality/valueThis study offers a behavioral measurement approach free from validity issues found in self-reported surveys, direct observations and interviews. The collected data offered new perspectives on existing social theories within a new environment of computerized, enterprise social media.
Mitigating financial leakages through effective money laundering investigation
Authors: Syed Mustapha Nazri Sharifah Nazatul Faiza , Zolkaflil Salwa , Omar Normah 
Published: January 2019

Purpose
This paper aims to conduct a comparison on the effectiveness of the law enforcement agencies (LEAs) of Australia and Malaysia in investigating money laundering cases by looking into the legal system and operational issues faced in conducting the investigation.

Design/methodology/approach
The purpose of this paper is to review and analyze the data collected from the Financial Action Task Force (FATF) Mutual Evaluation Report, focusing on the information outlined in the third chapter. The legal system and operational issues cover the area of technical compliance and effectiveness compliance, which were introduced in the latest FATF Evaluation Methodology issued in 2013.

Findings
The results show that both countries have the power needed to investigate money laundering and terrorism financing under their respective Anti-Money Laundering Act. However, Australia is seen to have a better investigative support system to assist LEAs during the investigation process. This explains the reason for difficulties in increasing the number of prosecutions for money laundering and terrorism financing cases. Hence, improvement actions are needed in curbing this issue.

Practical implications
The result suggests that Malaysia should strengthen the cooperation, coordination and capacity among LEAs to ensure effective targeting, investigation and prosecution of money laundering. The government should also revise the money laundering investigation time frame and broaden the power of LEAs in retrieving information during the investigation process. Malaysia should also enhance the investigative support system, which will be helpful for LEAs in gathering sufficient evidence to support their money laundering charges. Unlimited power in gathering evidence is prominent to charge money launders as it helps to gather information required for prosecution.

Originality/value
Prior literature focuses on the prevention mechanism, where this paper aims to focus on detection and investigation mechanism focusing on money laundering investigation conducted by LEAs. Lack of study on money laundering investigation calls for this research to be done to understand the strengths and weaknesses to improve its effectiveness in the future.
A framework for enterprise risk identification and management: the resource-based view
Authors: Mishra Birendra K. , Rolland Erik , Satpathy Asish , Moore Michael 
Published: January 2019

Purpose
This study aims to examine the factors influencing enterprise risk management and propose a framework for identifying and explaining the components of enterprise risk management. To enable broader analytical thinking about risk factors, the framework utilizes the resource-based theory to link various classes of risks to an extended set of organizational resources.

Design/methodology/approach
The paper opted for an exploratory study using a sample from an online survey. The survey subjects were recruited from the membership database of the American Institute of Certified Public Accountants, focusing primarily on CFOs. The survey consisted of six sections: demographics, a section on each of the four risk types included in ERM: strategic risk, operational risk, financial risk and hazard risk, and exit questions (where very general questions about ERM were asked). The survey yielded a data set of 227 valid responses.

Findings
Using the associated sample survey data, the paper provides empirical validation of the proposed framework that managers in any organizations could use to identify and manage risks.

Research limitations/implications
The proposed model does have limitations that predominantly exist from the fact that human judgment in decision-making is not always data-driven, and hence, a proper risk exposure could be ignored based on pure arguments of cost and benefits from domain experts. Therefore, researchers and practitioners are encouraged to test the proposed framework further.

Practical implications
Risk exposure is not a snapshot event in an organization’s time horizon. Rather, risk identification is an ongoing process and the proposed framework allows organizations to handle increasing complex risks and/or identifying them based on how the organizational resources may be exposed over time. Managers could use a form of risk control analytics (monitoring dashboard of all identified risks under each interaction sets on a regular basis) to become more proactive in managing risk or exploiting opportunities across enterprise.

Originality/value
This paper fulfills an identified need to study how enterprise risks exposure can be proactively assessed and managed.
Path planning method based on discontinuous grid partition algorithm of point cloud for in situ printing
Authors: Lian Qin , Li Xiao , Li Dichen , Gu Heng , Bian Weiguo , He Xiaoning 
Published: January 2019

Purpose
Path planning is an important part of three-dimensional (3D) printing data processing technology. This study aims to propose a new path planning method based on a discontinuous grid partition algorithm of point cloud for in situ printing.

Design/methodology/approach
Three types of parameters (i.e. structural, process and path interruption parameters) were designed to establish the algorithm model with the path error and the computation amount as the dependent variables. The path error (i.e. boundary error and internal error) was further studied and the influence of each parameter on the path point density was analyzed quantitatively. The feasibility of this method was verified by skin in situ printing experiments.

Findings
Path point density was positively correlated with Grid_size and negatively related to other parameters. Point_space, Sparsity and Line_space had greater influence on path point density than Indentation and Grid_size. In skin in situ printing experiment, two layers of orthogonal printing path were generated, and the material was printed accurately in the defect, which proved the feasibility of this method.

Originality/value
This study proposed a new path planning method that converted 3D point cloud data to a printing path directly, providing a new path planning solution for in situ printing. The discontinuous grid partition algorithm achieved controllability of the path planning accuracy and computation amount that could be applied to different processes.
Malignant solitary fibrous tumor in the subcutis: Report of a rare superficial malignant type and review of published work
Authors: Kiyohara Takahiro , Tanimura Hirotsugu , Takewaki Haruka , Suzuki Kenji 
Published: January 2019

AbstractAn 82‐year‐old Japanese man presented with a 90 mm × 80 mm subcutaneous nodule on the left chest, not connected to the pleura, described as hypointense on T1‐weighted magnetic resonance imaging. Histologically, a well‐demarcated nodule demonstrated a patternless pattern composed of hemangiopericytoma‐like and short storiform patterns from the subcutis into deeper tissue. Antler‐like branching blood vessels and keloidal‐type collagen bundles were seen. Myxoid change was seen in hypocellular areas. Bizarre cells and multinucleated giant cells could be easily identified. Approximately 5 mitoses per 10 high‐power fields could be detected. The majority of proliferating spindle cells were positive for CD34, CD99 and BCL2 expression. Signal transducer and activator of transcription (STAT)6 was strongly expressed in the nuclei. The Ki‐67 proliferation index was 60%. We performed wide local excision with a 30‐mm margin, along with resection of intercostal muscles, fasciae and periostea. Neither local recurrence nor distant metastases have occurred in 16 months of follow up. The present case is consistent with malignant solitary fibrous tumor in the subcutis histologically mimicking myxofibrosarcoma or undifferentiated pleomorphic sarcoma, definitively diagnosed by immunoexpression of STAT6. We performed a review of the published work and identified six previously reported patients with malignant superficial solitary fibrous tumor to validate the characteristics of this rare type. Four men and two women were included. The sarcomas involved the head area, trunk and thigh. Only one tumor‐associated death occurred despite excision and radiotherapy. Complete excision is a possible treatment choice for this tumor type.

Abstract18F‐Fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) is usually used to screen malignancy in patients with dermatomyositis (DM). Additionally, it is well known that FDG‐PET/CT provides valuable information for evaluating the activity of several inflammatory diseases, such as sarcoidosis, atherosclerosis, inflammatory bowel disease and rheumatoid arthritis. Therefore, the objective of this study was to evaluate the clinical usefulness of FDG‐PET/CT for the detection of inflammatory lesions and disease activity of both myopathy and interstitial lung disease (ILD) in DM patients. We measured the maximum standardized uptake value (SUVmax) in the muscles and lungs in 22 DM patients, and compared with magnetic resonance imaging (MRI) and high‐resolution computed tomography (HRCT) findings in the same muscle and lung regions as well as with clinical findings. We found that the location of increased FDG uptake was nearly consistent with the region of ILD and myositis detected by HRCT or MRI, respectively. There was a significant positive correlation between lung HRCT score and SUVmax in each lung. Serum Krebs von den Lungen‐6 levels also revealed significant positive correlation with total SUVmax of right and left lungs. Regarding FDG‐PET/CT and myopathy, total SUVmax in the muscles was significantly correlated with serum cytokeratin levels. Our results suggest that FDG uptake (SUVmax) might be useful for not only the detection of malignant tumors, but also the evaluation of the location and activity of ILD and myositis in DM patients.
Botfly infections impair the aerobic performance and survival of montane populations of deer mice, Peromyscus maniculatus rufinus

Abstract

Elevations >2,000 m represent consistently harsh environments for small endotherms because of abiotic stressors such as cold temperatures and hypoxia.

These environmental stressors may limit the ability of populations living at these elevations to respond to biotic selection pressures—such as parasites or pathogens—that in other environmental contexts would impose only minimal energetic‐ and fitness‐related costs.

We studied deer mice (Peromyscus maniculatus rufinus) living along two elevational transects (2,300–4,400 m) in the Colorado Rockies and found that infection prevalence by botfly larvae (Cuterebridae) declined at higher elevations. We found no evidence of infections at elevations >2,400 m, but that 33.6% of all deer mice, and 52.2% of adults, were infected at elevations <2,400 m.

Botfly infections were associated with reductions in haematocrit levels of 23%, haemoglobin concentrations of 27% and cold‐induced VO2max measures of 19% compared to uninfected individuals. In turn, these reductions in aerobic performance appeared to influence fitness, as infected individuals exhibited 19‐34% lower daily survival rates.

In contrast to studies at lower elevations, we found evidence indicating that botfly infections influence the aerobic capabilities and fitness of deer mice living at elevations between 2,000 and 2,400 m. Our results therefore suggest that the interaction between botflies and small rodents is likely highly context‐dependent and that, more generally, high‐elevation populations may be susceptible to additional biotic selection pressures.

Curriculum requirements and subsequent civic engagement: is there a difference between ‘forced’ and ‘free’ community service?
Authors: Henderson Ailsa , Brown Steven D. , Pancer S. Mark 
Published: January 2019

AbstractDespite figures showing the growth of mandatory community service programmes, there is mixed empirical evidence of their effectiveness. This paper addresses the relationship of mandated community service to one of its purported aims: subsequent volunteerism. It compares current volunteerism among four university student cohorts: those doing no service in secondary school, those volunteering with no requirement, those volunteering both before and after the introduction of a requirement, and those introduced to service through a requirement. The analysis indicates that (1) students who were introduced to service through a mandated programme exhibit current levels of engagement no greater than non‐volunteers; (2) this relationship stems largely from the different service experiences of our four cohorts and relates to the fact that service satisfaction and duration, as well as background variables account for current levels of civic engagement. The findings suggest that mandatory service programmes might well be failing the very population they seek to target, particularly in weaker, less structured programmes.

Published: January 2019

ObjectiveTo develop claims‐based measures of comprehensiveness of primary care physicians (PCPs) and summarize their associations with health care utilization and cost.Data Sources and Study SettingA total of 5359PCPs caring for over 1 million Medicare fee‐for‐service beneficiaries from 1404 practices.Study DesignWe developed Medicare claims‐based measures of physician comprehensiveness (involvement in patient conditionsandnew problem management) and used a previously developedrange of servicesmeasure. We analyzed the association ofPCPs’ comprehensiveness in 2013 with their beneficiaries’ emergency department, hospitalizations rates, and ambulatory care‐sensitive condition (ACSC) admissions (each per 1000 beneficiaries per year), and Medicare expenditures (per beneficiary per month) in 2014, adjusting for beneficiary, physician, practice, and market characteristics, and clustering.Principal FindingsEach measure varied acrossPCPs and had low correlation with the other measures—as intended, they capture different aspects of comprehensiveness. For patients whosePCPs’ comprehensiveness score was at the 75th vs 25th percentile (more vs less comprehensive), patients had lower service use (P < 0.05) in one or more measures:involvement with patient conditions: total Medicare expenditures, −$17.4 (−2.2 percent); hospitalizations, −5.5 (−1.9 percent); emergency department (ED) visits, −16.3 (−2.4 percent);new problem management: total Medicare expenditures, −$13.3 (−1.7 percent); hospitalizations, −7.0 (−2.4 percent);EDvisits, −19.7 (−2.9 percent);range of services:EDvisits, −17.1 (−2.5 percent). There were no significant associations between the comprehensiveness measures andACSCadmission rates.ConclusionsThese measures demonstrate strong content and predictive validity and reliability. Medicare beneficiaries ofPCPs providing more comprehensive care had lower hospitalization rates,EDvisits, and total Medicare expenditures.

Published: January 2019

ObjectiveTo examine the relationship between food swamps and hospitalization rates among adults with diabetes.Data SourcesBlue Cross Blue Shield Association Community Health Management Hub® 2014, AHRQ Health Care Cost and Utilization Project state inpatient databases 2014, and HHS Area Health Resources File 2010‐2014.Study DesignCross‐sectional analysis of 784 counties across 15 states. Food swamps were measured using a ratio of fast food outlets to grocers. Multivariate linear regression estimated the association of food swamp severity and hospitalization rates. Population‐weighted models were controlled for comorbidities; Medicaid; emergency room utilization; percentage of population that is female, Black, Hispanic, and over age 65; and state fixed effects. Analyses were stratified by rural‐urban category.Principal FindingsAdults with diabetes residing in more severe food swamps had higher hospitalization rates. In adjusted analyses, a one unit higher food swamp score was significantly associated with 49.79 (95 percent confidence interval (CI) = 19.28, 80.29) additional all‐cause hospitalizations and 19.12 (95 percent CI = 11.09, 27.15) additional ambulatory care‐sensitive hospitalizations per 1000 adults with diabetes. The food swamp/all‐cause hospitalization rate relationship was stronger in rural counties than urban counties.ConclusionsFood swamps are significantly associated with higher hospitalization rates among adults with diabetes. Improving the local food environment may help reduce this disparity.

Published: January 2019

Abstract

Leaf and wood separation is a key step to allow a new range of estimates from Terrestrial LiDAR data, such as quantifying above‐ground biomass, leaf and wood area and their 3D spatial distributions. We present a new method to separate leaf and wood from single tree point clouds automatically. Our approach combines unsupervised classification of geometric features and shortest path analysis.

The automated separation algorithm and its intermediate steps are presented and validated. Validation consisted of using a testing framework with synthetic point clouds, simulated using ray‐tracing and 3D tree models and 10 field scanned tree point clouds. To evaluate results we calculated accuracy, kappa coefficient and F‐score.

Validation using simulated data resulted in an overall accuracy of 0.83, ranging from 0.71 to 0.94. Per tree average accuracy from synthetic data ranged from 0.77 to 0.89. Field data results presented and overall average accuracy of 0.89. Analysis of each step showed accuracy ranging from 0.75 to 0.98. F‐scores from both simulated and field data were similar, with scores from leaf usually higher than for wood.

Our separation method showed results similar to others in literature, albeit from a completely automated workflow. Analysis of each separation step suggests that the addition of path analysis improved the robustness of our algorithm. Accuracy can be improved with per tree parameter optimization. The library containing our separation script can be easily installed and applied to single tree point cloud. Average processing times are below 10 min for each tree.

AbstractMost cancers arise in old individuals, which also accumulate senescent cells. Cellular senescence can be experimentally induced by expression of oncogenes or telomere shortening during serial passage in culture. In vivo, precursor lesions of several cancer types accumulate senescent cells, which are thought to represent a barrier to malignant progression and a response to the aberrant activation of growth signaling pathways by oncogenes (oncogene toxicity). Here, we sought to define gene expression changes associated with cells that bypass senescence induced by oncogenic RAS. In the context of pancreatic ductal adenocarcinoma (PDAC), oncogenic KRAS induces benign pancreatic intraepithelial neoplasias (PanINs), which exhibit features of oncogene‐induced senescence. We found that the bypass of senescence in PanINs leads to malignant PDAC cells characterized by gene signatures of epithelial‐mesenchymal transition, stem cells, and mitochondria. Stem cell properties were similarly acquired in PanIN cells treated with LPS, and in primary fibroblasts and mammary epithelial cells that bypassed Ras‐induced senescence after reduction of ERK signaling. Intriguingly, maintenance of cells that circumvented senescence and acquired stem cell properties was blocked by metformin, an inhibitor of complex I of the electron transport chain or depletion of STAT3, a protein required for mitochondrial functions and stemness. Thus, our studies link bypass of senescence in premalignant lesions to loss of differentiation, acquisition of stemness features, and increased reliance on mitochondrial functions.
