Exploring a market curiosity: an examination of the Super Bowl Indicator
Authors: Thompson Thomas H. , Sen Kabir C. 
Published: February 2017

Purpose
The purpose of this paper is to provide a comprehensive initial evaluation of the Super Bowl Indicator (SBI) from 1966 to 2015.

Design/methodology/approach
The authors evaluate the predictive ability of the SBI over two different time periods on four stock market indexes. Also, the authors compare the SBI predictive ability with other alternative indicators based on Super Bowl results as well as that of the January barometer (JB). As a robustness check, the authors examine whether the JB can predict Super Bowl outcomes. The authors use Granger causality to reduce the threat of spurious correlation.

Findings
The SBI surpasses the competition in both time periods, but it is evident that its predictive powers have waned since 1989. The authors find that the pre-Super Bowl January performance of the New York Stock Exchange is an impressive predictor of whether a team from the original National Football Conference won the big game between 1967 and 1988. Also, for the 1989-2016 period, the authors observe that the JB is a significant predictor whether the pre-game favorite wins or loses.

Originality/value
This study makes several contributions to the literature. The authors examine the SBI against four market indexes (Dow Jones Industrial Average, Standard and Poor’s 500 Index, and NASDAQ) with raw and point spread-adjusted scores. Testing a corollary to the SBI, this study is the first to examine the influence of the JB (sometimes called the January effect) on Super Bowl results.
Beyond earnings: do EBITDA reporting and governance matter for market participants?
Authors: Cormier Denis , Demaria Samira , Magnan Michel 
Published: February 2017

Purpose
The purpose of this paper is to investigate whether formally disclosing an earnings before interests, taxes, depreciation, and amortization (EBITDA) number reduces the information asymmetry between managers and investors beyond the release of GAAP earnings. The paper also assess if EBITDA disclosure enhances the value relevance and the predictive ability of earnings.

Design/methodology/approach
The authors explore the interface between GAAP and non-GAAP reporting as well as the impact of corporate governance on the quality of non-GAAP measures.

Findings
Results suggest that EBITDA reporting is associated with greater analyst following and with less information asymmetry. The authors also document that EBITDA reporting enhances the positive relationship between earnings and stock pricing as well as future cash flows. Moreover, it appears that corporate governance substitutes for EBITDA reporting for stock markets. Hence, EBITDA helps market participants to better assess earnings valuation when a firm’s governance is weak. Inversely, when governance is strong, releasing EBITDA information has a much smaller impact on the earnings-stock price relation.

Originality/value
The authors revisit the issue of how corporate governance relates with earnings quality by considering the potentially confounding effect of EBITDA reporting; it appears that such reporting substitutes for governance in moderating the relation between governance and earnings quality.
Modeling product market competition and reporting quality: the transitional economy of China
Authors: Iqbal Amjad , Rao Zia-ur-Rehman , Tauni Muhammad Zubair , Jebran Khalil 
Published: February 2017

Purpose
The purpose of this paper is to examine the role of product market competition in shaping a firm’s reporting quality (RQ).

Design/methodology/approach
This research uses an aggregate measure of a firm’s RQ, considering both the absolute level of discretionary accruals (DA) and the quality of accruals, using modified Jones model and Francis et al. (2005) accruals quality model, respectively. Whereas, the Herfindahl-Hirschman index and the Lerner index are used to measure product market competition. Further, this study considers the transitional economy of China and employs panel data estimation techniques for testing the hypothesized relationships.

Findings
This study finds that firms operating in more competitive industries are associated with higher RQ. This association still prevails when analysis is done using the component measures of RQ (i.e. the absolute level of DA and the quality of accruals). Overall, the empirical results provide evidence on the disciplining role of product market competition among Chinese firms.

Practical implications
Given the complex governance structures and specific kind of agency problems in Chinese corporations, this study suggests that product market competition may play an external disciplining role to improve the corporate information environment.

Originality/value
This research explores the role of product market competition for a firm’s RQ in Chinese-listed companies, while the prior studies on the same topic are mostly from the developed countries.
Inequity of sacrifice and marital satisfaction in Chinese young couples

Published: February 2017

There is an emerging body of research focusing on the positive and negative effects of sacrifice on relationship quality, but few of them have investigated the effects of the inequity of sacrifice. In the light of social exchange theory and equity theory, this study examines the roles inequity of sacrifice plays in marital satisfaction in China. Based on the questionnaires completed by 115 Chinese young couples, we find that wives’ perceived inequity of sacrifice, rather than husbands’ perceived inequity or the actual inequity of sacrifice, is predictive to both spouses’ marital satisfaction. In addition, wives’ perceived overbenefit positively predicts, while underbenefit negatively predicts both spouses’ marital satisfaction, which means when wives perceive their husbands’ sacrifice more than themselves, both of them have higher satisfaction. In accordance with social exchange theory but not equity theory, our findings highlight the important and subtle roles perceived inequity of sacrifice behaviours plays in the marriages of Chinese young couples.Practitioner points

The importance of perceived inequity implies that clients’ perceptions should be paid more attention than the content of their stories
The strong predictive power of wives’ but not husbands’ perceived inequity suggests we should keep gender difference in mind when working with couples, especially young couples
Young couples may care about their own advantages more than the equity of their relationship, which should be accommodated in clinical work

SummaryLittle is currently known on the microbial populations colonizing the sheep large intestine, despite their expected key role in host metabolism, physiology and immunity. This study reports the first characterization of the sheep faecal microbiota composition and functions, obtained through the application of a multi‐omic strategy. An optimized protocol was first devised for DNA extraction and amplification from sheep stool samples. Then, 16S rDNA sequencing, shotgun metagenomics and shotgun metaproteomics were applied to unravel taxonomy, genetic potential and actively expressed functions and pathways respectively. Under a taxonomic perspective, the sheep faecal microbiota appeared globally comparable to that of other ruminants, with Firmicutes being the main phylum. In functional terms, we detected 2097 gene and 441 protein families, finding that the sheep faecal microbiota was primarily involved in catabolism. We investigated carbohydrate transport and degradation activities and identified phylum‐specific pathways, such as methanogenesis for Euryarchaeota and acetogenesis for Firmicutes. Furthermore, our approach enabled the identification of proteins expressed by the eukaryotic component of the microbiota. Taken together, these findings unveil structure and role of the distal gut microbiota in sheep, and open the way to further studies aimed at elucidating its connections with management and dietary variables in sheep farming.

AbstractMost of the water diversions on the Sacramento and San Joaquin Rivers (California, United States) and their tributaries are currently unscreened. These unscreened diversions are commonly used for irrigation and are potentially harmful to migrating and resident fishes. A large flume (test section: 18.29 m long, 3.05 m wide and 3.20 m high) was used to investigate the hydraulic fields near an unscreened water diversion under ecologically and hydraulically relevant diversion rates and channel flow characteristics. We investigated all combinations of three diversion rates (0.28, 0.42, and 0.57 m3/s) and three sweeping velocities (0.15, 0.38, and 0.61 m/s), with one additional test at 0.71 m3/s and 0.15 m/s. We measured the three‐dimensional velocity field at seven cross sections near a diversion pipe and constructed regression equations of the observed maximum velocities near the pipe. Because the velocity components in three directions (longitudinal, transverse, and vertical) were significantly greater near the diversion pipe inlet compared with those farther from it, they cannot be neglected in the modeling and design of fish guidance and protection devices for diversion pipes. Our results should be of great value in quantifying the hydraulic fields that are formed around fish guidance devices to design more effective protection for fishes from entrainment into unscreened water‐diversion pipes.

Published: February 2017

BackgroundAnaphylaxis during general anaesthesia is rare but often severe. Identification of the cause of anaphylaxis and recommendation of a range of drugs or agents likely to be safer for future surgery is a collaborative venture between the allergists and the anaesthesiologists, but it often poses a significant challenge.MethodsA total of 31 patients who attended the Drug Allergy Unit at University College London Hospital with suspected perioperative anaphylaxis between March 2013 and January 2016 were reviewed retrospectively.ResultsThe culprit drug was identified in 21 patients (67.7%): antibiotics (n = 11, 52.3%), neuromuscular blocking agents (n = 8, 38.1%), morphine (n = 1, 4.8%) and gelofusine (n = 1, 4.8%). No cause was identified in six patients (19.4%), and four patients (12.9%) had non‐allergic reactions.ConclusionOur results confirm that antibiotics and neuromuscular blocking agents are common causative agents of perioperative anaphylaxis in the United Kingdom.

Published: February 2017

BackgroundThe mortality rate in patients with severe community‐acquired pneumonia (SCAP) is high. We investigated the 5‐year mortality rate and causes of death in a patient population treated for SCAP in our intensive care unit (ICU), and compared the mortality rate in patients with or without chronic obstructive pulmonary disease (COPD) as comorbidity.MethodsThis retrospective study, which covers a period of 10 years, included patients aged > 18 years admitted to our ICU with SCAP as primary diagnosis and in need of mechanical ventilation for more than 24 h. Data were collected from the ICU internal database and the patients' medical records. The times of death were collected from the Norwegian National Registry, and the causes of death from the Norwegian Cause of Death Registry.ResultsHundred and seventy three patients were included in the study. The 5‐year mortality rate for the total study population was 57.2%. There were no significant differences in the mortality rate between the group with COPD and the group without COPD (61.2% vs. 54.7%, P = 0.43). There was a wide range of comorbidities. The most common were COPD, myocardial infarction and diabetes mellitus. The two main causes of death after discharge were COPD (17 deaths) and cardiovascular diseases (seven deaths).ConclusionsThe 5‐year mortality rate of the study population was high (57.2%). COPD did not seem to be a risk factor for mortality compared to non‐COPD patients. The most common causes of death after discharge were COPD and cardiovascular diseases.

BackgroundInteractions between the liver, the gut, and the immune system are critical components of alcoholic liver disease (ALD). The aim of this study was to explore the associations between alcohol‐induced liver injury, endotoxemia, and inflammation at admission and over time during abstinence, as well as to examine the sex‐related differences in these parameters in alcohol‐dependent individuals admitted to an alcohol treatment program.MethodsA cohort of 48 otherwise healthy participants with alcohol use disorder, but no clinical signs of alcoholic liver injury (34 males [M]/14 females [F]) admitted to an alcohol detoxification program, was stratified into 2 groups based on baseline plasma alanine aminotransferase (ALT) levels (as a marker of liver injury). Group 1 (ALT < 40 U/l, 7M/8F) and Group 2 (ALT ≥ 40 U/l, 27M/6F) were identified. Plasma biomarkers of liver damage, endotoxemia, and inflammation were examined at baseline, day 8, and day 15 of the admission. The drinking history was also evaluated.ResultsSixty‐nine percent of patients had elevated ALT and other markers of liver damage, including aspartate aminotransferase and cytokeratin 18 (CK18 M65 and CK M30) at baseline, indicating the presence of mild ALD. Elevated CK18 M65:M30 ratio suggested a greater contribution of necrotic rather than apoptotic hepatocyte cell death in the liver injury observed in these individuals. Females showed greater elevations of liver injury markers compared to males, although they had fewer drinks per day and shorter lifetime duration of heavy drinking. Liver injury was associated with systemic inflammation, specifically, elevated plasma tumor necrosis factor‐alpha levels. Compared to patients without liver injury, patients with mild ALD had greater endotoxemia (increased serum lipopolysaccharide levels), which decreased with abstinence and this decrease preceded the drop in CK18 M65 levels.ConclusionsThe study documented the association of mild alcohol‐induced liver injury and endotoxemia, which improved with 2 weeks of abstinence, in a subset of individuals admitted to an alcohol detoxification program.
Osteolipoma of the buccal mucosa: a case report
Authors: Firth NA , Allsobrook OFL , Patel M 
Published: February 2017

AbstractLipomas are benign mesenchymal neoplasms of soft tissue that can be found commonly in any part of the human body. Their presence in the oral mucosa is uncommon, however, with approximately 4% of the cases occurring in the oral cavity. Oral lipomas are likely to have originated from mature adipose tissue and there are several histological variants of lipomas described, which are identified according to the predominant type of tissue in addition to adipose tissue. A rare lipoma variant, known as an osteolipoma or an ossifying lipoma, may occur; however, little has been written this type of lipoma characterized by a classical lipoma with areas of osseous metaplasia. This paper describes a case of an osteolipoma involving the buccal mucosa of an adult patient.
The Role of Outstanding Foundation Awards in Fund Families

Published: February 2017

AbstractThis study employs unique data concerning “Outstanding Foundation Awards” in Taiwan to investigate the determinant factors of winning awards and the contributions of award funds to the respective fund families. Our results show that fund fees, performance, age, volatility, family fees, and family award winning experiences are important predictors of winning awards. One‐, three‐, and five‐year award funds charge higher fund fees over a 1‐year post‐award period; however, they do not experience an increase in their own fund/family flows after winning the awards.
Applications of the water drinking test in glaucoma management
Authors: Susanna Remo , Clement Colin , Goldberg Ivan , Hatanaka Marcelo 
Published: February 2017

AbstractIntraocular pressure (IOP) peaks and means have been considered important factors for glaucoma onset and progression. However, peak IOP detection depends only on appropriated IOP checks at office visits, whereas the mean IOP requires longitudinal IOP data collection and may be affected by the interval between visits. Also, IOP peak assessment is necessary to verify if the peak pressure of a given patient is in target range, to evaluate glaucoma suspect risk, the efficacy of hypotensive drugs and to detect early loss of IOP control. The water‐drinking test has gained significant attention in recent years as an important tool to evaluate IOP peaks and instability. The main objective of this review was to present new findings and to discuss the applicability of the water‐drinking test in glaucoma management.
Primal‐Dual Optimization for Fluids

Published: February 2017

AbstractWe apply a novel optimization scheme from the image processing and machine learning areas, a fast Primal‐Dual method, to achieve controllable and realistic fluid simulations. While our method is generally applicable to many problems in fluid simulations, we focus on the two topics of fluid guiding and separating solid‐wall boundary conditions. Each problem is posed as an optimization problem and solved using our method, which contains acceleration schemes tailored to each problem. In fluid guiding, we are interested in partially guiding fluid motion to exert control while preserving fluid characteristics. With our method, we achieve explicit control over both large‐scale motions and small‐scale details which is valuable for many applications, such as level‐of‐detail adjustment (after running the coarse simulation), spatially varying guiding strength, domain modification, and resimulation with different fluid parameters. For the separating solid‐wall boundary conditions problem, our method effectively eliminates unrealistic artefacts of fluid crawling up solid walls and sticking to ceilings, requiring few changes to existing implementations. We demonstrate the fast convergence of our Primal‐Dual method with a variety of test cases for both model problems.

ObjectivesThis study was designed to evaluate the usefulness of intra‐operative frozen section for the evaluation of microscopic extrathyroidal extension (ETE) in papillary thyroid carcinoma (PTC).DesignRetrospective cohort study.SettingDong‐A University Medical Center, Busan, Korea.ParticipantsThree hundred and sixty‐four patients who underwent thyroid surgery from January 2000 to December 2010 with PTC confined to one unilateral lobe as diagnosed using preoperative ultrasonography were enrolled.Main outcome measuresThe patients who had microscopic ETE on frozen section were classified into “group A,” and those who did not have microscopic ETE on frozen section were classified into “group B.” Clinicopathologic factors including age, gender, size of the tumour, extent of operation, ETE, multifocality, bilaterality, lymph node metastasis and recurrence were compared between the two groups.ResultsOf the 364 patients enrolled, ETE was confirmed in 100 patients (group A, 27.5%) on frozen biopsy. The nodule size in group A (0.94±0.87 cm) was larger than that in group B (0.86±0.79 cm) (P=.042). In group A, 15 patients (15%) showed multifocality and 11 patients (14.47%) showed bilaterality. In group B, 37 patients (14.02%) showed multifocality and seven patients (43.35%) showed bilaterality. They did not differ significantly between the two groups (P=.811, P=.182). There was a higher frequency of lymph node metastases in group A (52/86, 60.47%) than in group B (7/16, 43.75%, P=.214). Recurrence was observed in only two patients who had received thyroid lobectomy as the initial surgery in group A.ConclusionsIntra‐operative frozen biopsy can be a useful method for identifying the microscopic ETE. During the surgery, it can also help the surgeon to decide the optimal extent of surgery and the need for central compartment neck dissection in PTC patients.

Published: February 2017

ObjectivesDespite the excellent overall survival of 92%‐97% in early glottic cancer, recurrence rates of 13%‐20% have not improved in the last decades. The engulfment and cell motility protein 3 (ELMO3) have been described as prognostic marker in patients with lung cancer. The aim of this study was to investigate the expression of ELMO3 in early laryngeal cancer patients treated with TLM and to evaluate its prognostic significance on clinical outcome.Design, setting and participantForty‐eight patients with glottic carcinoma (T1N0M0) that underwent primary treatment with TLM between 1994 and 2012 were analysed. ELMO3 expression of the tumour was assessed using immunohistochemistry and correlated with clinical data.Main outcome measureOverall survival, disease‐specific survival (DSS) and disease‐free survival (DFS) ratesResultsPositive ELMO3 expression was found in 23% of the patients and was correlated with poor DSS and DFS (P<.05).ConclusionThis is the first study to show a prognostic effect of positive ELMO3 expression in early glottic carcinoma patients.
