A probabilistic approach to the Stochastic Job-Shop Scheduling problem

Uncertainty exists in almost any manufacturing process, and its effect may be detrimental to the manufacturing outcomes. In the Stochastic Job Shop Scheduling Problem (SJSSP), some of the process parameters are random variables, in particular the processing time. This paper considers another facet of the SJSSP, which is the probability for success (or failure) of a manufacturing job and its effect on other jobs. The paper presents a mathematical model for determining the expected manufacturing cost, and proposes heuristics for reducing that cost. The fundamental model is based on a single resource (e.g. a single machine) and a set of manufacturing jobs, each characterized by a cost and a probabilistic distribution for success. A failure causes either a re-work of the failed job, or restarting the entire process from the first job. Since the problem is NH Hard, a set of heuristics for scheduling the jobs is proposed, and simulation results validate these heuristics.

Risky Sexual Behavior and Associated Factors among Cobblestone Chiseling Daily Laborer, Addis Ababa, Ethiopia

Background: In recent years, cobble stone road creation has become one of the most successful infrastructure and job creation in Ethiopia, with tremendous benefits for the poor rural and urban population segment. Identifying factors associated with cobble stone chiselers laborers risk behaviors is crucial for developing effective prevention strategies. Hence, this study aimed to assess risky sexual behavior and associated factors among cobblestone chiselers, in Hana Mariam, Nifas Silk Lafto Sub City, and Addis Ababa, Ethiopia. Methods: Community based cross sectional study was conducted in March 2015 among cobblestone chiselers. The data entry and analysis was carried out using SPSS version 16. Association between dependent and independent variables were tested using bivariate logistic analysis, CI at 95%. P value less than 0.05 was considered significant. Results: The prevalence risky sexual behavior of respondents was 79.4%. Nearly half of the study participants 44.5% were age group 25-29 years. About 26.4% of cobble stone chiselers have had 2-5 sexual partners in the past 12 months and 42.2% of study participants did not used condom in the first sexual intercourse. Single by marital status were about nine times more likely had risky sexual practices as compared to divorce (AOR=8.762, 95% CI=4.672- 16.433) in the study participant whose educational status from grade 5-8 and grade 9-12 were about 3 and 4 times more likely practices risky sexual behavior than those individuals whose educational level were write and read (AOR=3.084, 95% CI=1.328-7.162) and (AOR=4.224, 95% CI=1.532-11.629). Those who drink alcohol daily were 6.277 times more likely practicing risky behavior as compared to those not drunk (AOR=6.277, 95% CI=1.622-24.298). Conclusion and recommendation: The prevalence of risky sexual behavior among cobble stone chiselers daily laborers was higher; therefore, critical health education that aimed at bringing behavioral changes should be planned and implemented by giving emphasis on identified risk sexual behavior.

DRL-Scheduling: An Intelligent QoS-Aware Job Scheduling Framework for Applications in Clouds

As an increasing number of traditional applications migrated to the cloud, achieving resource management and performance optimization in such a dynamic and uncertain environment becomes a big challenge for cloud-based application providers. In particular, job scheduling is a non-trivial task, which is responsible for allocating massive job requests submitted by users to the most suitable resources and satisfying user QoS requirements as much as possible. Inspired by recent success of using deep reinforcement learning techniques to solve AI control problems, in this paper, we propose an intelligent QoS-aware job scheduling framework for application providers. A deep reinforcement learning-based job scheduler is the key component of the framework. It is able to learn to make appropriate online job-to-VM decisions for continuous job requests directly from its experiences without any prior knowledge. Experimental results using synthetic workloads and real-world NASA workload traces show that compared with other baseline solutions, our proposed job scheduling approach can efficiently reduce average job response time (e.g., reduced by 40.4% compared with the best baseline for NASA traces), guarantee the QoS at a high level (e.g., job success rate is higher than 93% for all simulated changing workload scenarios), and adapt to different workload conditions.

Fuzzy-based trusted security for mobile grid systems

In mobile grid system, the main factor to be considered while deploying in real world application is security. Otherwise, the framework would be incomplete and impractical. In order to provide full security, successful job execution and high resource availability, in this paper, we propose to design a fuzzy-based trusted security for mobile grid systems. In this technique, the trust index value of each node is estimated using fuzzy logic. Here the metrics grid residence time, reputation and degree of maliciousness are considered as input for the fuzzy logic and the trust index value is determined as output. Based on the trust index, GS allocates the grid node when it receives the service request. Also, as the trust index is calculated and updated by the GS, the malicious nodes cannot modify or destroy the values. By simulation results, we show that the proposed technique offers high security and high resource availability.

Exploring the Occupational Context of Independent Male Escorts Who Seek Male Clients: The Case of Job Success.

Male sex work (MSW) research has been generally limited to the examination of “social problems.” Although there have been studies on occupational aspects, pointed examinations of the occupational environment, detailing the contemporary nature of the field, are rare. Research on nuances of the occupational context of MSW, providing insight on the rapidly changing face of the field, is wanting. Semistructured interviews were conducted with 20 escorts in Brisbane, Australia. This study explored job success, indicating that success in the field was well articulated, possibly highlighting that male independent escorting is becoming a professionalized occupation, with a shift away from current stigmatized understandings.

Diversity, disparate impact, and discrimination pursuant to Title VII of US civil rights laws

PurposeWhile the words diversity, disparate impact, and discrimination are commonly read and heard by working adults and professionals, they can at times be confusing and fearful to some managers. The purpose of this paper is to provide an overview of a specific aspect of US civil rights laws – the disparate impact theory. The authors provide an analysis based on the statute, case law interpreting, and applying the statute, administrative guidelines from the Equal Employment Opportunity Commission, as well as legal and management commentary. The paper illustrates the requirements of a plaintiff employee’s initial case based on the disparate impact theory. The challenging causation component which requires some degree of statistical evidence is given particular attention. Limitations to the paper are stated at the beginning; and recommendations to managers are explored and provided toward the end of the paper.Design/methodology/approachIt is a legal paper which covers all the laws related to discrimination based on disparate impact and disparate treatment theories. Actual court cases up until this month and Americans laws related to this concept are reviewed and critically discussed.FindingsThe salient feature of disparate impact is that this legal theory allows a plaintiff job applicant or employee to sustain a case of illegal discrimination without providing any evidence of a discriminatory motive. As opposed to the disparate treatment liability is imposed based on disproportionate adverse results and not discriminatory intent.Research limitations/implicationsThis paper deals with the disparate impact theory pursuant to Title VII of the Civil Rights Act. However, it must be pointed out that the disparate impact theory is also applicable to claims arising under the Americans with Disabilities Act and the Age Discrimination in Employment Act. Since the focus of this paper is Title VII federal and state constitutional issues, such as the applicability of the 14th Amendment’s Equal Protection clause that may arise in disparate impact cases involving government entities will not be addressed.Practical implicationsManagers and employees can protect themselves in the workplace from illegal discriminatory practices. Initially, employers and managers must be aware of the distinction between a disparate impact case and a disparate treatment case with the latter requiring evidence of intentional discrimination. Evidence, of course, can be direct or circumstantial or inferential. Whereas in a disparate impact case there is no intentional discrimination; and as such proof of discriminatory intent is not required. Rather, the employee has to present evidence that the employer’s neutral on-its-face employment policy or practice caused an adverse disproportionate impact on the employee as a member of a protected class.Social implicationsHuman resources professionals and managers must become educated in diversity laws in order to provide an inclusive workplace for all employees and candidates. Employers have legitimate areas of concern in hiring and promoting employees; and the courts are cognizant of employer responsibilities; and thus the employers must be able to show how specific knowledge, skills, education, training, backgrounds, as well as height, weight, strength, and dexterity are legitimate qualifications that directly relate to successful job performance.Originality/valueThis is an original paper by the authors.

Technology Update: System Adds Reliability, Efficiency to Attaching Well Construction and Completion Tools

Technology Update The secure placement of tools and accessories along well construction and completion strings is essential to executing downhole applications. In wellbore cementing, for example, job success depends on efficient mud removal and cement displacement around the tubular. Both of these objectives may be compromised if channeling occurs, where the cement does not spread evenly in all directions. Prevention of channeling depends on designing the right cementing program, which includes achieving the optimal standoff between the string being cemented and the open hole. Selecting the right centralizers and planning their location along the string are critical to achieving standoff. And securing the centralizers to keep them from sliding along the pipe is also essential to prevent damage to the string and the risk of leaving junk in the hole if the string must be removed from the wellbore. A new attachment system designed for simplicity, reliability, and ease of installation has been developed by Ace Oil Tools to overcome the limitations of traditional methods used to secure tools and accessories to drilling and completion strings. The patented design includes slim-profile male and female collars that are slid onto API casing joints and pressed together with a lightweight machine. As they are pressed together, corresponding ramps work to engage slip wickers to the joint to produce a very high holding force while maintaining a slim profile. The collars also feature a ratchet mechanism to prevent them from coming apart, forming a permanent lock to the joint. Current Industry Practices Historically, the most common method for holding casing equipment in place has been to use stop collars that are secured to the liner with set screws. These simple, inexpensive tools are used when only a low holding force is needed and their relatively high profile does not prevent the string from passing through restrictions. This type of stop collar is not typically suitable for critical wells or in drilling programs that use semi-flush or flush-joint connections. If the collar fails, there are no couplings within the string to push accessories past restrictions, possibly preventing the string from reaching total depth. Collar failure can also result in suboptimal standoff, pipe damage, and junk left in the hole. As the offshore drilling industry evolved, centralizer subs were developed as a more reliable solution. These short tubulars are threaded into the string between joints. Subs contain machined profiles to interface with the centralizers to prevent them from sliding along the string as they are run into the wellbore. Because the profiles are integral to the sub, they will not fail under high loads. Some of the issues with centralizer subs are their high expense and the limitations they impose on string design. Only one centralizer per joint can be run, and it can only be placed in a suboptimal location between the joints.

Transferring innovative research into practical wisdom: the case of permeation grouting

For decades, permeation grouting has been used as a cost-effective low disturbance ground improvement technology that allowed geotechnical engineers to help strengthening the soils and provide proper control of water flow. While permeation grouting can be a very useful solution, the design of an appropriate grouting program can be the difference between a successful job and an expensive on-the-go repair. However, current grout design relies heavily on rules of thumb and outdated charts. The geotechnical investigation is rarely targeted towards grouting design and the final grouting decisions are made based on index measurements such as fines content or soil classification at most. The collective “past experience” is more commonly used for final grouting design than any other geotechnical design despite that flow of grouts through porous media is a very complex phenomenon owing to the diversity of possible flow stoppage mechanisms involved. For some cases, rheological blocking occurs due to viscous grouts; however, in most cases, permeation is controlled by filtration. Despite the complexity of the science behind permeation grouting, practitioners often reference in situ heterogeneity and variability to dismiss the need for a more systematic design approach. However, heterogeneity and variability never stopped geotechnical engineers from performing proper design based on measured engineering properties of the soil and this should be the case for grouting as well. Particularly, with all the recent advances to grouting materials and its accompanying additives, grouting is now possible with more concentrated suspensions (lower w/c ratios) and the grouts are more “flowable” than ever before. These advances are making most of existing charts and common rules of thumb obsolete and therefore, it is the optimal time to implement recent advances in grouting research into common practice. Recent research on the topic highlights the complexities of grouting and the potential for implementing advanced laboratory testing to properly characterize the grouts and design it for field specific in situ conditions and desired final improved properties. This paper discusses these limitations in practice, advances in research and provides a case study where these advances were implemented to design a site-specific grout.

Nivo olova u krvi kod dece koja žive u blizini fabrike za reciklažu akumulatora u Zajači

Olovo je toksični teški metal čija je široka upotreba dovela do zagađenja u životnoj sredini i zdravstvenih problema. Deca su posebno ugrožena, s obzirom da je olovo najveći efekat ima tokom njihovog razvoja, a moguća je kumulativna izloženost iz različitih izvora. Nivoi preko 70 mikrograma po decilitru krvi mogu dovesti do encefalopatije i smrti deteta. Niži nivoi dovode do smanjene kognitivne sposobnosti i promena u ponašanju. Cilj ove studije bio je utvrđivanje nivoa olova u krvi kod dece koja žive u blizini fabrike za reciklažu akumulatora u Zajači, i upoređivanje ovih vrednosti sa limitima koje već nekoliko decenija propisuje Centar za kontrolu bolesti u Sjedinjenim Američkim Državama. Studija je izvedena u decembru 2011. godine u Zajači. Deca i roditelji su ispunili upitnik u vezi sa mestom stanovanja, zanimanjem roditelja, udaljenošću od fabrike, kao i različitim simptomima koji su se javljali kod dece. Od svakog deteta je uzet uzorak krvi u kom je meren nivo olova. U studiji je učestvovalo 75 dece iz Zajače. Prosečna udaljenost od fabrike za reciklažu bila je 300 metara. Samo 13% dece iz Zajače imalo je nivo olova u krvi niži od limita Centra za kontrolu bolesti od 10 mikrograma po decilitru krvi iz 1991. godine, dok je samo jedno dete imalo nivo niži od limita od 5 mikrograma po decilitru krvi iz 2012. godine. Čak 26 dece (34%) imalo je nivo od preko 20 mikrograma olova u decilitru krvi. Visoki nivoi olova u krvi negativno utiču na kognitivnu sposobnost dece, što se najčešće meri standardizovanim IQ testom. To utiče na uspeh u školi, postignuti nivo obrazovanja, a samim tim u uspeh na tržištu rada, te je negativno povezan sa potencijalnim prihodima i standardom kasnije u životu.

Who needs innate ability to succeed in math and literacy? Academic-domain-specific theories of intelligence about peers versus adults.

Individuals' implicit theories of intelligence exist on a spectrum, from believing intelligence is fixed and unchangeable, to believing it is malleable and can be improved with effort. A belief in malleable intelligence leads to adaptive responses to challenge and higher achievement. However, surprisingly little is known about the development of academic-domain-specific theories of intelligence (i.e., math vs. reading and writing). The authors examined this in a cross-section of students from 1st grade to college (N = 523). They also examined whether students hold different beliefs about the role of fixed ability in adult jobs versus their own grade. The authors' adult-specific beliefs hypothesis states that when children learn societally held beliefs from adults, they first apply these beliefs specifically to adults and later to students their own age. Consistent with this, even the youngest students (1st and 2nd graders) believed that success in an adult job requires more fixed ability in math than reading and writing. However, when asked about students in their own grade, only high school and college students reported that math involves more fixed ability than reading and writing. High school and college students' math-specific theories of intelligence were related to their motivation and achievement in math, controlling for reading and writing-specific theories. Reading and writing-specific theories did not predict reading and writing-specific motivations or achievement, perhaps because students perceive reading and writing as less challenging than math. In summary, academic-domain-specific theories of intelligence develop early but may not become self-relevant until adolescence, and math-specific beliefs may be especially important targets for intervention.

Exploring the Costs of Providing Assistive Technology as a Reasonable Accommodation

The provision of assistive technology (AT) as an accommodation is often associated with a cost. Employer concerns about the cost of providing AT can be a barrier for individuals with disabilities (IWD) who are seeking employment. Rehabilitation counselors & students should be prepared to address employer concerns regarding the cost of an accommodation in order to facilitate successful job placement and/or retention of IWD. This study evaluated the average cost of providing AT in the workplace compared to the average cost of providing other types of accommodations, as reported to the Job Accommodation Network (JAN) by employers. Results of this study show that there is no significant difference in the cost of providing AT in comparison to the cost of providing other types of accommodations (N=72). Rehabilitation professionals can use this information when exploring strategies for negotiating for the use of assistive technology by consumers as an accommodation.

THE EFFECT OF ENTREPRENEURIAL COMPETENCY ON PRODUCT INNOVATION AND BUSINESS PERFORMANCE: EMPIRICAL CASES OF FASHION BUSINESS IN CENTRAL JAVA, INDONESIA

INTRODUCTION:Various literature describe how businesses can be successful (Ahmad et al., 2010; Baum et al., 2001; Chandler & Hanks, 1994; Chandler & Jansen, 1992). One who runs business successful has the entrepreneurial competence (Chandler & Hanks, 1994; Chandler & Jansen, 1992; Cheng & Dainty, 2003; Huck & McEwen, 1991; Markman, 2007). Competence, possessed by an entrepreneur enables business with competitive advantage compared to others (Meutia et al., 2012). Competence is a combination and integration between knowledge, skills and behaviour (Kyndt & Baert, 2015). Entrepreneurial competency is nothing but capable of making the company effective (Robles & Zarraga-Rodriguez, 2015) so that the goals set can be achieved.Fashion clothes or business is undergoing significant development in Indonesia. Various outlets started popping up due to the needs of consumers with regards to fashion, especially clothes, greatly increased. Model and style of the clothes are getting increasingly diverse today. which makes consumers tend to make purchases because consumers want to follow new trends. Fashion items are unique consumer products marked with short life cycles, high demand volatility, predictability, lower sales and impulsive purchase behavior(Bruce et al., 2004; Moon et al., 2010). Innovation has become an important part in business suits. Innovation is the key to drive the performance in fashion SMEs.The purpose of this study is to examine the influence of competency in entrepreneurial innovation product and business performance. The research questions are as follows:Q1. How does the influence of entrepreneurial competency on product innovation?Q2. How does the influence of product innovation on business performance?Q3. How does the influence of entrepreneurial competency on business performance?LITERATURE REVIEW:Entrepreneurial Competency:Competency is the ability to coordinate the deployment of assets that helped the company to achieve its purpose (Sanchez et al., 1996). Competency enables companies to use their resources efficiently and/or effectively. Competency is a logical extension of the resource-based view (Lado et al., 1992). Because of the complex, tacit knowledge, competencies, and specific companies, they can be a source of competitive advantage (Reed et al., 1990). because competence involves a complex trade-off between the skills of many people, they are embedded in the fabric of the Organization '(Day, 1994).The competence of a businessman became an important factor in achieving excellence in performance to ensure continuous growth and success of a business in the midst of a competitive business environment. Hence the importance of entrepreneurial competence has increased over the past few decades because of the strategic role played by the human factors in particular employers of the company business.Bird (1995) shows that 'entrepreneurial competence' is defined as the underlying characteristics as specialized knowledge, motif, nature, self image, social roles and skills that produce business births, survival and/or growth. Man et al. (2002) mentioned that entrepreneurial competence is defined as the ability of entrepreneurs to do a successful job role.. Johnson and Winterton (1999) observed that various skills and competencies are needed to run a small company qualitatively as well as quantitatively which is different from that of the skills required to run a larger organization. This is at least partly correct because the context of the focus is on individual entrepreneurship (Hunt and Meech, 1991).Product Innovation:Corporate Research Foundation found that one of the keys to bring success to a company is the power of innovation (Cook, 1998). Such innovation should be supported with human resource of high creativity in the company. This innovation is able to bring up something new that ultimately makes strong positioning. …
