Detecting Opportunistic Special Items
Authors: Cain Carol Anilowski , Kolev Kalin S. , McVay Sarah 
Published: November 2019

The frequency of special items has increased dramatically over time, offering a convenient conduit for the inappropriate classification of past, present, and future recurring expenses as nonrecurring. Identifying this misclassification is especially important in light of the pervasive use of non–generally accepted accounting principles earnings in recent periods because special items offer camouflage for excluded recurring expenses. Building on prior research, we propose a method for identifying the predicted level of special items, attributing any excess to opportunism, and demonstrate the importance of this partitioning for financial-statement users. In particular, we provide evidence that the opportunistic portion of special items is associated with lower future earnings, cash flows, and returns. We conclude that this portion of special items is more likely to contain opportunistically misclassified recurring expenses that should have been recognized as such in prior, current, or future periods. Thus, we provide a meaningful partition of special items that should be useful to investors, analysts, creditors, auditors, and regulators because each of these parties must assess the implications of special items.

Procurement with Unforeseen Contingencies
Authors: Herweg Fabian , Schmidt Klaus M. 
Published: November 2019

A buyer who wants to procure a complex good is often aware that there may be flaws in her initial design, but she does not know what they look like. Potential sellers who discover flaws have no incentive to reveal them early if the buyer uses a price-only auction. We derive an efficient mechanism that induces all sellers to report flaws early and that allocates the project to the seller with the lowest cost. We show that this can be implemented with a simple two-stage auction that does not require any prior knowledge of the set of possible flaws. This paper was accepted by Yan Chen, decision analysis.
Wolves at the Door: A Closer Look at Hedge Fund Activism
Authors: Wong Yu Ting Forester 
Published: November 2019

Most investor coordination remains undisclosed. I provide empirical evidence on the extent and consequences of investor coordination in the context of hedge fund activism, in which potential benefits and costs from coordination are especially pronounced. In particular, I examine whether hedge fund activists orchestrate “wolf packs”—that is, groups of investors willing to acquire shares in the target firm before the activist’s campaign is publicly disclosed via a 13D filing—as a way to support the campaign and strengthen the activist’s bargaining position. Using a novel hand-collected data set, I develop a method to identify the formation of wolf packs before the 13D filing. I investigate two competing hypotheses: the Coordinated Effort Hypothesis (wolf packs are orchestrated by lead activists to circumvent securities regulations about “groups” of investors) and the Spontaneous Formation Hypothesis (wolf packs spontaneously arise because investors independently monitor and target the same firms at about the same time). A number of tests rule out the Spontaneous Formation Hypothesis and provide support for the Coordinated Effort Hypothesis. Finally, the presence of a wolf pack is associated with various measures of the campaign’s success. This paper was accepted by Brian Bushee, accounting.
Physical activity and fatigue in adults with inflammatory bowel disease (IBD): a systematic review
Authors: Radford Shellie J , Janiszewski Helen , Moran Gordon W 
Published: November 2019

Background: Fatigue is frequently reported in inflammatory bowel disease (IBD). In IBD patients, physical activity levels have been shown to have an impact on, and be impacted by, disease activity. Yet, to date, there have been no systematic reviews considering the impact of physical activity on levels of IBD fatigue. This study aims to investigate whether physical activity has the potential to improve levels of IBD fatigue in adults with IBD. Methods: Systematic database search (CINAHL, Embase, PsychInfo, PsycARTICLES, AMED, Medline) and hand searching were conducted on 3 March 2019. Searches were restricted to ‘human’, ‘adult’, ‘primary research’ and ‘English language’ publications. No time limit was set. Quality appraisal and data extraction was undertaken by at least two reviewers. Results: The searches yielded 32 publications; two studies were included in the review. Physical activity was found to be inhibited by higher fatigue levels, lowering health-related quality of life (HRQoL), but also as a means of reducing fatigue, subsequently improving HRQoL. Conclusion: Results identified relationships between IBD fatigue and physical activity. However, further research is warranted, as exploring this information would allow better understanding of IBD fatigue and inform future work on possible fatigue interventions in IBD.

Background: Patient satisfaction and factors that influence it have become an important indicator of the quality of digestive endoscopy. Aims: This study aimed to define variables that make endoscopic procedures acceptable and those that predispose patients to repeat them under the same conditions. Methods: Consecutive outpatients undergoing endoscopic examinations completed questionnaires, administered by the nursing staff, before and after the procedure. Univariate analysis and multivariate logistic regression models were designed to investigate independent variables associated with the following outcomes of interest. Findings: Most patients experienced pain and anxiety before and during the procedure, considered the procedure unacceptable and felt unwilling to repeat it. Conclusion: Symptoms strictly related to the patient, specifically anxiety and pain and type of sedation received, were the main factors related to satisfaction and willingness to repeat the procedure under the same conditions.

Faktor-faktor yang menyebabkan gagalnya gugatan perdata lingkungan hidup dan kehutanan antara lain substansi hukum terkait perkara, ketidaktepatan penggugat dalam menentukan dasar gugatan, masalah kompetensi, kesulitan dalam pembuktian, keterbatasan kualitas dan kuantitas penegak hukumnya, sarana dan prasarana, serta kendala eksekusi.
URGENSI HARMONISASI HUKUM NASIONAL TERHADAP PERKEMBANGAN HUKUM GLOBAL AKIBAT GLOBALISASI
Authors: Sulistyawan Aditya Yuli 
Published: November 2019

Pengaruh globalisasi dalam tatanan hukum nasional Indonesia sangatlah besar. Hal ini harus disikapi dengan keinginan kuat dari segenap bangsa Indonesia dalam rangka pembangunan hukum nasional yang lebih baik. Hal demikian semakin dapat dipahami mengingat globalisasi merupakan suatu gejala yang tidak dapat ditolak ataupun dihindari oleh negara mana pun yang tidak ingin terkucil dalam percaturan internasional. Misalnya sejak ratifikasi terhadap Agremeent Establishing The World Trade Organization (WTO), Indonesia harus mengharmonisasikan seluruh hukum nasional yang terkait dengan ketentuan-ketentuan dalam WTO. Selain itu, lahirnya berbagai Undang-Undang mengenai HAM di Indonesia adalah implikasi lahirnya instrumen-instrumen HAM internasional, utamanya Statuta Roma 1998.
Counterexamples to the tilting and (p,r)-filtration conjectures
Authors: Bendel Christopher P. , Nakano Daniel K. , Pillen Cornelius , Sobaje Paul 
Published: November 2019

Abstract
In this paper the authors produce a projective indecomposable module for the Frobenius kernel of a simple algebraic group in characteristic p that is not the restriction of an indecomposable tilting module. This yields a counterexample to Donkin’s longstanding Tilting Module Conjecture. The authors also produce a Weyl module that does not admit a p-Weyl filtration. This answers an old question of Jantzen, and also provides a counterexample to the

Architecture For Automation System Metrics Collection, Visualization and Data Engineering – HAMK Sheet Metal Center Building Automation Case Study
Authors: Dang Khoa , Trotskii Igor 
Published: November 2019

Abstract
Ever growing building energy consumption requires advanced automation and monitoring solutions in order to improve building energy efficiency. Furthermore, aggregation of building automation data, similarly to industrial scenarios allows for condition monitoring and fault diagnostics of the Heating, Ventilations and Air Conditioning (HVAC) system. For existing buildings, the commissioned SCADA solutions provide historical trends, alarms management and setpoint curve adjustments, which are essential features for facility management personnel. The development in Internet of Things (IoT) and Industry 4.0, as well as software microservices enables higher system integration, data analytics and rich visualization to be integrated into the existing infrastructure. This paper presents the implementation of a technology stack, which can be used as a framework for improving existing and new building automation systems by increasing interconnection and integrating data analytics solutions. The implementation solution is realized and evaluated for a nearly zero energy building, as a case study.
Standard negation in Awa Pit: From synchrony to diachrony
Authors: Krasnoukhova Olga , van der Auwera Johan 
Published: November 2019

AbstractThis study deals with clausal negation in Awa Pit, a Barbacoan language spoken in South America. By bringing together the data on negation from different varieties of the language, we present an analysis of synchronic patterns of negation marking. Based on the variation we suggest a number of innovations in the negation system, for which we put forward diachronic scenarios. Some innovations are likely to be contact-induced, whereas others are products of language-internal diachronic processes. The latter involve mechanisms associated with a classical ‘Jespersen Cycle’. However, Awa Pit offers us very non-classical Jespersen’s Cycles – at best. The case of Awa Pit is instructive as some of the scenarios that we suggest are likely to be relevant for other languages or languages families.
Parentheticals revisited: The case of Dutchdenken
Authors: Nuyts Jan , Janssens Karolien 
Published: November 2019

AbstractThis paper presents an investigation into the diachrony of the parenthetical uses of the mental state verbdenken‘think’ in Dutch. It reviews the literature on the emergence of parentheticals, which predominantly focuses on English. Supported by a systematic diachronic corpus study, it argues that the facts of Dutch (in particular: its word order properties, which are quite different from those in English) are not obviously in line with the most important traditional views (including the well know hypothesis that the parentheticals are the result of a reduction of the full complementing use of the relevant verbs). Instead, the data offer arguments for an alternative hypothesis: the parentheticals may originate in a combination of two main clauses, of the kind present in direct quote expressions (as inI thought: Oh no, he is doing it again).
On the development of two progressive constructions in U̠t-Ma’in
Authors: Paterson Rebecca 
Published: November 2019

AbstractU̠t-Ma’in (Kainji, Benue-Congo), spoken in northwestern Nigeria, has two morphosyntactically distinct progressive constructions – the Intransitive Progressive Construction and the Transitive Progressive Construction. This paper presents the synchronic structure of each construction, proposed historical sources of the distinct morphological pieces, and a comparison of the U̠t-Ma’in Progressive Constructions with cognate elements from four Kainji language clusters. No single source component has grammaticalized to mark progressive aspect in U̠t-Ma’in. Rather, the combination of several elements created the progressive. Formal changes in several morphosyntactic elements within each of the constructions provide evidence that originally nominalized verb forms are gradually becoming less noun-like and more verb-like. These developments are examples of constructionalization, as the Progressive Constructions exist as new form-meaning pairs distinct from the source. These formal changes also show signs of adjustment, whereby a construction moves toward isomorphism, that is, a one-to-one correspondence between form and meaning. Specifically, various stages of morphological loss are evident in particular lexemes when used in U̠t-Ma’in Progressive Constructions, gradually spreading throughout the lexicon.
Design and Analysis of a Dispersion-engineered and Highly Nonlinear Rib Waveguide for Generation of Broadband Supercontinuum Spectra
Authors: Alizadeh Mohammad Reza , Seifouri Mahmood 
Published: November 2019

AbstractIn this paper, a waveguide consisting of a core of As2Se3 chalcogenide glass and the upper and lower claddings of MgF2 with two zero-dispersion wavelengths (ZDW) has been proposed. By optimization of the dimensions of the core and the claddings, their effects on the dispersion curve have been investigated and a suitable structure with a flat dispersion curve, an effective mode area of ​​1.6 μm2 in a pump wavelength of 2.8 μm, and hence, a nonlinear coefficient greater than 34 w−1 m−1 has been obtained. A broadband supercontinuum in a wavelength range of 1.5 μm to 15 μm has been generated by applying an input pulse with duration of 100 fs and a maximum power of 2 kw to this waveguide. Due to the large width of the supercontinuum generated (SCG), the short length of the waveguide (maximum 5 mm), and a low input power, this structure is suitable for use in optical integrated circuits and its various applications.

Authors: Ürkek Bayram , Şengül Mustafa , Akgül Halil İbrahim , Kotan Tuba Erkaya 
Published: November 2019

Abstract
The aim of this study was to determine the influence of sloe berry (SB) addition at different ratios on the physical, chemical, antioxidant, colour and sensory properties and mineral contents of ice creams. The increment of SB led to the an increase of titratable acidity, overrun, viscosity and ash values, first dripping and complete melting times; in contrast, it decreased the total solid, pH and fat values. Mn and Zn values were affected significantly (P < 0.05) by the addition of SB but other element levels were not affected. L* and b* values decreased significantly in all samples as compared with control sample, while a*, H°, C* and ∆E* increased significantly with addition of SB. Antioxidant activity was the highest in the sample containing 15 % SB (w/w) among ice cream samples. The ice cream samples containing 15 % SB had higher score than the control sample in terms of colour and appearance, gumming structure and general acceptability.

Abstract

Background
According to GLOBOCAN 2018, oral cancer was reported as the second highest cancer prevalent in India. Despite the several therapies available for oral cancer treatment, tumor recurrence and distant metastasis persist. This study investigates the anticancer potential of Persicaria odorata, commonly known as Vietnamese coriander, used widely in traditional systems of medicine for the treatment of inflammation, stomach ailments, tumors, etc.

Methods
The crude methanolic extract of P. odorata (MPo) was prepared. The anticancer properties of MPo on SAS cells and other human oral squamous cell carcinoma cell line were evaluated using in vitro experimental conditions. The phytochemical constituents present in the MPo were also determined.

Results

Persicaria odorata possesses antiproliferative, antisurvival, antimetastatic activities, and induced cell cycle arrest in the G2 phase. It inhibited Akt-mammalian target of rapamycin (mTOR) signaling pathway and also downregulated the expression of essential proteins that are involved in tumorigenesis such as cyclin D1, cyclooxygenase 2 (COX2), survivin, matrix metalloproteinase-9 (MMP-9), and vascular endothelial growth factor-A (VEGF-A). Moreover, the presence of flavonoids and quinones also revealed the anticancer activity of the plant.

Conclusion
Overall, our study concludes that P. odorata exhibits its anticancer properties through the downregulation of Akt/mTOR signaling pathway in a dose-dependent manner.

A note on vertices of indecomposable tensor products
Authors: Linckelmann Markus 
Published: November 2019

Abstract
G. Navarro raised the question of when two vertices of two indecomposable modules over a finite group algebra generate a Sylow p-subgroup.
The present note provides a sufficient criterion for this to happen.
This generalises a result by Navarro for simple modules over finite p-solvable groups, which is the main motivation for this note.

Predication over aspects of human individuals
Authors: Geist Ljudmila 
Published: November 2019

Abstract
Predicate nouns in German, as well as in other languages, may occur bare or with an indefinite article. This alternation is possible with role nouns, which refer to well-established aspects of individuals such as professions and nationalities. Bare NPs differ from indefinite NPs in that they have restricted meaning, are number neutral and are restricted in modifiability. In the literature, these peculiarities received different explanations. The new account combines previous analyses and is based on the following assumptions: the noun that projects an indefinite NP denotes a kind, while the noun projecting a bare NP denotes a capacity. This difference corresponds to the difference in predication: indefinite NPs predicate about the whole individual assigning it membership in a certain kind, while bare NPs predicate only about one social aspect of the individual, identifying it with a certain capacity. Since bare predication concerns only one aspect of the individual, it is partial. Bare predication can now be considered under a broader view of partial predication, a phenomenon very common in argument alternations, and can be analyzed with the tools that have proved effective in this domain. The approach to bare predication taken here thus has a larger empirical coverage.
Mature cystic teratoma of the pancreas: A rare cystic neoplasm
Authors: Kim HeeJoon , Koh YangSeok 
Published: November 2019

Abstract
Mature cystic teratoma of the pancreas is an extremely rare benign neoplasm. Only 51 cases have been reported in the literature. Its cystic nature often appears to have malignant potential in preoperative image studies. Moreover, no characteristic features could be shown on image studies, such as abdominal CT scan or pancreas MRI. The accurate diagnosis is generally obtained after surgical resection. We present a rare case of a 53-year-old male with mature cystic teratoma of the pancreas, which was confirmed on pathology after laparoscopic distal pancreatectomy.
