Title: Oral health status of workers exposed to acid fumes in phosphate and battery industries in Jordan
Abstract: OBJECTIVES To investigate the prevalence and nature of oral health problems among workers exposed to acid fumes in two industries in Jordan. SETTING Jordan's Phosphate Mining Company and a main private battery factory. DESIGN Comparison of general and oral health conditions between workers exposed to acid fumes and control group from the same workplace. SUBJECTS AND METHODS The sample consisted of 68 subjects from the phosphate industry (37 acid workers and 31 controls) drawn as a sample of convenience and 39 subjects from a battery factory (24 acid workers and 15 controls). Structured questionnaires on medical and dental histories were completed by interview. Clinical examinations were carried out to assess dental erosion, oral hygiene, and gingival health using the appropriate indices. Data were statistically analysed using Wilcoxon rank-sum test to assess the significance of differences between results attained by acid workers and control groups for the investigated parameters. RESULTS Differences in the erosion scores between acid workers in both industries and their controls were highly significant (P<0.05). In both industries, acid workers showed significantly higher oral hygiene scores, obtained by adding the debris and calculus scores, and gingival index scores than their controls (P<0.05). The single most common complaint was tooth hypersensitivity (80%) followed by dry mouth (77%) on average. CONCLUSION Exposure to acid fumes in the work place was significantly associated with dental erosion and deteriorated oral health status. Such exposure was also detrimental to general health. Findings pointed to the need of establishing appropriate educational, preventive and treatment measures coupled with efficient surveillance and environmental monitoring for detection of acid fumes in the workplace atmosphere.

Title: A fast high utility itemsets mining algorithm
Abstract: Association rule mining (ARM) identifies frequent itemsets from databases and generates association rules by considering each item in equal value. However, items are actually different in many aspects in a number of real applications, such as retail marketing, network log, etc. The difference between items makes a strong impact on the decision making in these applications. Therefore, traditional ARM cannot meet the demands arising from these applications. By considering the different values of individual items as utilities, utility mining focuses on identifying the itemsets with high utilities. As "downward closure property" doesn't apply to utility mining, the generation of candidate itemsets is the most costly in terms of time and memory space. In this paper, we present a Two-Phase algorithm to efficiently prune down the number of candidates and can precisely obtain the complete set of high utility itemsets. In the first phase, we propose a model that applies the "transaction-weighted downward closure property" on the search space to expedite the identification of candidates. In the second phase, one extra database scan is performed to identify the high utility itemsets. We also parallelize our algorithm on shared memory multi-process architecture using Common Count Partitioned Database (CCPD) strategy. We verify our algorithm by applying it to both synthetic and real databases. It performs very efficiently in terms of speed and memory cost, and shows good scalability on multiple processors, even on large databases that are difficult for existing algorithms to handle.

Title: On the Effectiveness of Direct Shipping Strategy for the One-Warehouse Multi-Retailer R-Systems
Abstract: We consider the problem of integrating inventory control and vehicle routing into a cost-effective strategy for a distribution system consisting of one depot and many geographically dispersed retailers. All stock enters the system through the depot and is distributed to the retailers by vehicles of limited constant capacity. We assume that each one of the retailers faces a constant, retailer specific, demand rate and that inventory is charged only at the retailers but not at the depot. We provide a lower bound on the long run average cost over all inventory-routing strategies. We use this lower bound to show that the effectiveness of direct shipping over all inventory-routing strategies is at least 94% whenever the Economic Lot Size of each of the retailers is at least 71% of vehicle capacity. The effectiveness deteriorates as the Economic Lot Sizes become smaller. These results are important because they provide useful guidelines as to when to embark into the much more difficult task of finding cost-effective routes. Additional advantages of direct shipping are lower in-transit inventory and ease of coordination.

Title: Two-echelon distribution systems with vehicle routing costs and central inventory
Abstract: We consider distribution systems with a single depot and many retailers each of which faces external demands for a single item that occurs at a specific deterministic demand rate. All stock enters the systems through the depot where it can be stored and then picked up and distributed to the retailers by a fleet of vehicles, combining deliveries into efficient routes. We extend earlier methods for obtaining low complexity lower bounds and heuristics for systems without central stock. We show under mild probabilistic assumptions that the generated solutions and bounds come asymptotically within a few percentage points of optimality (within the considered class of strategies). A numerical study exhibits the performance of these heuristics and bounds for problems of moderate size.

Title: Self-citation is the hallmark of productive authors, of any gender
Abstract: It was recently reported that men self-cite >50% more often than women across a wide variety of disciplines in the bibliographic database JSTOR. Here, we replicate this finding in a sample of 1.6 million papers from Author-ity, a version of PubMed with computationally disambiguated author names. More importantly, we show that the gender effect largely disappears when accounting for prior publication count in a multidimensional statistical model. Gender has the weakest effect on the probability of self-citation among an extensive set of features tested, including byline position, affiliation, ethnicity, collaboration size, time lag, subject-matter novelty, reference/citation counts, publication type, language, and venue. We find that self-citation is the hallmark of productive authors, of any gender, who cite their novel journal publications early and in similar venues, and more often cross citation-barriers such as language and indexing. As a result, papers by authors with short, disrupted, or diverse careers miss out on the initial boost in visibility gained from self-citations. Our data further suggest that this disproportionately affects women because of attrition and not because of disciplinary under-specialization.
