Change Operations and Their Consequences in AOP Evolution

Simple change operations to source code can cause unexpected behavior. In particular, two well-known problemat ic situations, fragile pointcuts and aspect interactions, pose serious challenges for the evolution of software with aspects. We believe that if developers are informed about the consequences of the change operations they are considering, they will be able to avoid various errors. This work analy zes the effects of change operations in AO applications. It proposes the Identification, Qualitative, and Quantity (IQQ) model as a conceptual approach to anticipating the consequences of change operations, along with BaLaLu, a tool that supports the IQQ model.
The Need to Accumulate Human Capital Across Levels of Export Intensity: Activating Resources that are Increasingly Difficult to Mobilise

With increasing levels of export intensity, firms begin to face new demands. The first set of resources brought to bear on the issues, and those resources that are most quickly mobilised, are the employees. Indeed, higher levels of exporting require activating relatively less mobile resources through the building of organisational structures and mechanisms for managing repositories of knowledge (particularly organisational specialisation and selectively hiring appropriately skilled staff). This paper explores the management of human capital across different levels of export activity in Australian manufacturing firms. Analyses were based on 90 Australian-headquartered manufacturing exporters that responded to a survey. Overall, the results support the notion that firms need to accumulate knowledge as they internationalise. These results are discussed in terms of their consequences for HRM practices.
Fabrication and properties of macroscopic carbon nanotube assemblies transforming from aligned nanotubes

Macroscale assemblies of well-aligned carbon nanotubes (CNTs) can inherit intrinsic properties from individual CNTs and at the same time ease handling difficulties that occur at nanometer scale when dealing with individual CNTs. Herein, simple fabrication processes are introduced to produce a variety of macroscale CNT assemblies, including well-aligned CNT bundles, CNT films, and CNT fibers, from the same starting material: spinnable CNT arrays. The electrical and mechanical properties of the as-prepared CNT assemblies have been investigated and compared. It is found that CNT films show an electrical conductivity of 145-250 S cm-1 which is comparable to CNT fibers, but two orders magnitude higher than that of conventional Bucky paper. CNT fibers exhibit diameter dependent tensile strength which is mainly attributed to the nonuniform twisting along the radial direction of fibers.
A Model for Sorting Activities to Be Outsourced in Civil Construction Based on ROR-UTADIS

The subcontractor’s selection problem is currently treated as a supply chain problem with a prequalification procedure to balance the main objectives of the client: cost, quality, and time. Unfortunately, most of the selection processes are analysed under the same methodology without considering that variations in project, type of activity, and other attributes should affect the chosen method. To provide a novel form of treating subcontractor’s selection, we proposed an additive sorting method to categorize activities to be outsourced in civil construction based on ROR-UTADIS method, which is a modification of the UTADIS method that includes new forms of supplying preference information. It was applied in the construction of a brewery in Brazil. It was perceived that the method is applicable and intuitive for decision makers, even though there are quite a few points to be taken, analysed to avoid misclassification.
Antioxidant capacity and antibacterial activity of different parts of mangosteen (Garcinia mangostana Linn.) extracts

Introduction. Mangosteen (Garcinia mangostana) is a tropical fruit that is famous for its edible pulp. This edible pulp makes up only 30% of the total fruit, while the remaining pericarp and seed are regarded as waste. Facing the increasing public demand for naturally safe foods and products, our study aimed to elucidate the antioxidant capacity and antibacterial activity of different parts of mangosteen, including the pericarp, pulp and seed. Materials and methods. The antioxidant capacities of mangosteen's pericarp, pulp and seed extracts were determined using the ferric reducing antioxidant power (FRAP) assay and 2,2- diphenyl-1-picrylhydrazyl (DPPH) assay, whereas antibacterial activity was determined using the disc diffusion method. Results. The pericarp extract exhibited higher antioxidant capaci- ties than those of pulp and seed extracts, with a Trolox equivalent antioxidant capacity (TEAC) value of 122.00 µM·g -1 and ferrous sulphate equivalent antioxidant capacity (FEAC) value of 18.99 mM·g -1 . All mangosteen extracts showed strong inhibition against Staphylococ- cus aureus ATCC11632, while only the pericarp extract was effective against Bacillus cereus ATCC10876. No inhibition against Escherichia coli ATCC10536 was observed. Conclusion. The outcomes of our study could facilitate future application of mangosteen waste as a bio- preservative in the food industry.

From Earth to Outer Space: Laser cleaning semiprecious quartz and a novel application for meteoritic metal

Varying the pulse duration, pulse frequency, and fluence (energy density) of conservation lasers can result in successful cleaning of mineralogical materials such as quartz crystals coated with iron oxide films and corroded iron meteorites. Semiprecious quartz is valued by specimen collectors for its euhedral crystal habit and is desirable for commercial applications given its uniform piezoelectric properties. Infrared laser pulses may provide a rapid means for removing metal oxide films from these rough crystals. Extraterrestrial minerals within meteorites provide scientists with valuable information about the origin of our solar system, as well as geologic events in the Earth’s deep history. Iron meteorite samples are typically mechanically sectioned and polished to reveal crystalline structures displayed in reflected light microscopy. However, the surfaces of these ironrich samples can easily oxidize when exposed to moisture and other environmental contaminants. Wet polishing methods, inappropriate handling, and atmospheric exposure can therefore result in surface corrosion in the form of iron oxy-hydroxide-hydrates (e.g. goethite and lepidocrocite). Further hydroxyl and chlorine uptake leads to formation of the mineral akaganéite (Fe3+O(OH,Cl)). The use of 1064 nm laser pulses at various durations and fluences, in both atmospheric conditions and aided by an argon purge, is explored in this study as a means to remove the corrosion products from an iron meteorite. This method avoids the removal of a significant mass of specimen material involved with grinding and polishing, without the introduction of additional exposure to water. Effects of laser treatment were monitored using scanning electron microscopy and energy dispersive x-ray spectrometry (SEM-EDS). The SEM-EDS “postmortem” evaluation of corrosion removal from iron meteorites establishes the nature of the specimen surface chemistry and morphology following laser cleaning. 1.0 Introduction Formatted: Justified Formatted: Font: (Default) Times New Roman, No underline, Font color: Black
Self-esteem- its influence and structural changes in the lives of tribal students of Kannur district, Kerala

Researchers are in tremendous controversy regarding self-esteem and its correlates. Self-esteem is an important pillar of psychological well-being. Most of the studies agree with this judgment. Adolescence is a period in which people try to be independent and they start to evaluate themselves self-esteem is a contributing factor for positive behavior. Tribal is the natural inhabitant of the forest or hilly area. They hesitate to keep good relationship with the outside community. But the present needs of life make them to come out side. But there they are supposed to face a lot of challenges. These people must be mentally competent. In this article the researcher tries to find out the level of self-esteem among the tribal students and the relationship between the socio-demographic characters and the self-esteem with special reference to the Kannur district of Kerala.

Determinants of Poverty in Rural Ethiopia: A Household Level Analysis

This paper investigates the dynamics of poverty in rural Ethiopia during the period from 1994 to 2009. In order to explore factors that decisively affect the possibility of falling into and exiting out of poverty, the paper uses six rounds of data and employs alternative dynamic probit model which handles the problem of serial correlation, unobserved individual heterogeneity, state dependence and the initial conditions problem. The estimation result shows that the likelihood of falling in to poverty in any round is a direct function of previous experience in poverty suggesting strong evidence for the existence of true state dependence. Socioeconomic variables like land size, oxen and other tropical livestock units have tremendous role in reducing the probability of falling into poverty. Additionally, while demographic characteristics and drought has significant effect in the northern part, cash crop production plays a vital role for households in southern Ethiopia. Finally, the paper draws important policy implications that can be helpful for policy making and enlighten appropriate intervention areas.
Goal orientations, contextual and situational motivational climate and competition goal involvement in Spanish athletes with cerebral palsy

This study examined the relationship between perception of contextual and situational motivational climate, goal orientations and competition goal involvement in Spanish athletes with cerebral palsy. Athletes (N= 57), completed inventories to assess perception of contextual and situational motivational climate, goal orientation and goal involvement. Results show that ego involvement was positively correlated with perception of contextual and situational coach ego involving motivational climate, and ego orientation. Analysis of hierarchical regression, reveled that competition task-involvement was predicted by the contextual task-involving motivational climate and competition ego involving was predicted only by ego orientation. Results are discussed in the context of conceptual basis of achievement goal perspective.
Study of Microwave Tomography Measurement Setup Configurations for Breast Cancer Detection Based on Breast Compression

Microwave tomography (MT) measurement setups for different configurations based on breast compression are compared to classical circular measurement setups. Configurations based on compression allow measuring the evanescent component of the scattered field and lead to a compact measurement setup that allows direct image comparison with a standard mammography system. The different configurations are compared based on the singular value decomposition (SVD) of the radiation operator for a 2D TM case. This analysis allows determining under which conditions the image quality obtained from the reconstructions can be enhanced. These findings are confirmed by a series of reconstructions of breast phantoms based on synthetic data obtained at a single frequency of operation.
Trade and agricultural policies in Malawi: Not all policy reform is equally good for the poor

The reduction of the existing global distortions to agricultural incentives is sometimes stated as a priority to fight poverty worldwide. But the impacts of global trade policy and domestic development policy reforms are rarely, if ever, compared. Despite technical limitations hindering rigorous comparison of the overall growth effects, also hampering cost-benefit analysis, this paper contributes at filling this gap by focusing on the comparison of the distributional poverty impacts of both types of policies. It uses the MIRAGE global computable general equilibrium –CGE- model feeding a national CGE model representing Malawi in 2007 linked to household survey to examine how different trade policy reforms by Malawi and the rest of the world would impact poverty in Malawi. The country’s recent agricultural growth history due to the Fertilizer Input Subsidy Program is replicated and compared with a more broad-based sectoral approach. The effects of accelerating growth in agriculture and downstream sectors are compared with those of integrating in the regional and multilateral markets. Non preferential trade policy reforms are found to be less favourable for poverty reduction of the poorest than regional integration or preferential integration. Faster intensification and diversification of agriculture is found to enable targeting the poorest that are less likely to be connected to international markets. Therefore, while policy reforms generating growth in general may be good for some poors, it is found that that not all policy reforms are equally good. Thus, despite the fact that trade policies could help fight poverty in Malawi, there are no substitute to development policies, and if undertaken simultaneously, their coherence should be checked thoroughly.
Cloverleaf Clusters: A Common Macrostructural Organization across Human Visual and Auditory Cortex

One of the fundamental properties of mammalian brains is that sensory regions of cor- tex are organized into multiple, functionally specialized cortical field maps (CFMs). An individual CFM is composed of two orthogonal topographical representations, reflect - ing two essential aspects of a sensory feature space. Each CFM is thought to subserve a specific computation or set of computations that underlie particular perceptual behaviors by enabling the comparison and combination of the information carried by the various specialized neuronal populations within this cortical region. Multiple adjacent CFMs, in turn, have now been shown by multiple laboratories to be organized in visual and auditory cortex into a macrostructural pattern called the cloverleaf cluster. CFMs within cloverleaf clusters tend to share properties such as receptive field distribution, cortical magnification, and processing specialization. This chapter will review the evidence for CFM and cloverleaf cluster organization across human visual and auditory cortex and will discuss the utility of these measurements for determining cortical structure and function and for investigating what changes occur in sensory cortex following various types of trauma or disease.
THE RHYZOSPHERE, BIOLOGY AND THE REGOLITH

The regolith has been broadly defined as “the layer of unconsolidated (non-cemented) material, including rock fragments, mineral grains and all other superficial deposits that rest on unaltered, solid bedrock” (Allaby 1998). Eggleton (2001) provides a more detailed definition: “the entire unconsolidated or secondarily recemented cover that overlies more coherent bedrock, that has been formed by weathering, erosion, transportations and / or deposition of the older material. The regolith thus includes fractured and weathered basement rocks, saprolites, soils, organic accumulations, volcanic material, glacial deposits, colluvium, alluvium, evaporitic sediments, aeolian deposits and ground water. ”
A NOVEL GUARANTEED COST CONTROL FOR HOPFIELD NEURAL NETWORKS WITH MULTIPLE TIME-VARYING DELAYS

This paper studies the problem of guaranteed cost control for a class of Hopfield delayed neural networks with multiple time-varying delays. The time delay is a continuous function belonging to a given interval, but not necessary to be differentiable. A cost function is considered as a nonlinear per- formance measure for the closed-loop system. The stabilizing controllers to be designed must satisfy some exponential stability constraints on the closed-loop poles. By constructing a set of augmented Lyapunov-Krasovskii functionals combined with Newton-Leibniz formula, a guaranteed cost controller is de- signed via memoryless state feedback control and new sufficient conditions for the existence of the guaranteed cost state-feedback for the system are given in terms of linear matrix inequalities (LMIs).
Classroom Micro-Expression Recognition Algorithms Based on Multi-Feature Fusion

The extraction of facial features is the key to micro-expression recognition. This paper puts forward a micro-expression recognition algorithm through multi-feature fusion. In this algorithm, the change of local binary pattern (LBP) feature distribution is correlated with projection error. For fast and accurate detection, the research data were all extracted from professional facial expression databases, the images had basically the same positions in each expression library, and the pure face image was acquired through manual segmentation from the selected expression library. Through comparison and its application in an intelligent classroom environment, it is proved that the proposed algorithm clearly outperforms the original LBP algorithm. The proposed method can be extended to other image recognition and classification problems.

Multidisciplinary Therapeutic Approach In Cervical Cancer Patients

Three hundred eleven patients were diagnosed histological as a cervix neoplasm in Vryheid District Hospital, Zululand Region, Kwazulu Natal Province from October 2004 until January 2008; one hundred ninety three patients were treated and followed up, 43 under multidisciplinary therapeutic approach and 150 with conventional modalities of treatments. One hundred eighteen patients weren’t properly treated and followed up, due to non treatment compliance and absenteeism to Primary Health Care and Hospital institutions. The Hysterectomies were necessary to be done in 58 patients from 193 total operated. The clinical evolution on the treated patients showed that the multidisciplinary approach was more effective than other isolated modalities of treatment. The level of recovering from their diseases on our 43 patients into the Natural and Bioenergetics Protocols was much better than others as well as the number of post operative and adjuvant complications were less. During the studied period 4 patients died from 43 into the Natural & Bioenergetics Protocols and 47 deaths were reported of 150 patients treated with conventional therapeutic modalities. The proper control, follow up and treatment of the patients affected by cervix neoplasm remains as a big challenge into the Health Department
A Stochastic Simulation Model of Alarm Response Strategies on a Telemetry Floor

The large quantity of alarms characteristic of clinical settings have resulted in nursing staff suffering from a phenomenon termed ‘alarm fatigue’. Alarm fatigue is desensitization via habituation – as these commonly heard noises cause caregivers to have delayed or no response to alarms. Alarm management was ranked number one on the annual top ten list of technology hazards afflicting healthcare institutions published by the ECRI Institute for 2012. Several healthcare organizations have established alarm fatigue as a priority concern, and are working to eradicate the issue from the healthcare environment by 2017. To better understand the problem, a simplified simulation model was created using Automod® to investigate the routine processes involved in responding to cardiac arrhythmia alarms in a telemetry unit as well as the sources of noise attributing to alarm fatigue. By quantifying these workflows and response strategies, this model can be utilized to aid administrators and managers in selecting alarm escalation times as well as modifying hospital protocols to minimize alarm response time and enhance nursing efficacy. The results also support the identification of hospital policy elements where clinical workflow could be augmented based on the physical layout of the telemetry floor, use of distributed alarm notification systems and staff roles and responsibilities.
Searching and Breeding for Structural Features of Flowers Correlated with High Nectar-Carbohydrate Production

Structural features of flowers correlated with high nectar-carbohydrate production are examined, particularly from studies of various agricultural and horticultural plants. Some of these floral traits, and nectar characteristics (volume, and sugar concentration and production) themselves are followed in studies of inheritance. Recommendations are given for characteristics indicative of high nectar yields, and for those traits best eliminated early in breeding programmes.
Simplified rotating tire models based on cylindrical shells with free boundary conditions

A number of studies have been previously concerned with vibrations of rotating tires. In order to capture detailed dynamics of a rotating tire, complex numerical models have been developed accounting for the nonhomogeneous structural properties of the tire belt and sidewall, structural-acoustic coupling and complex geometry description (including that of the wheel rim), under varying rotation speeds. Although a remarkable amount of details can be successfully modelled using such an approach, it can be rather difficult to parameterize the model, i.e. to establish a clear-cut relationship between a geometrical or material property of a tire and the corresponding change in the tire dynamics. Thus an alternative approach is employed within the scope of this study by modelling simplified tire geometries. The focus of the study is put onto modelling vibrations of the tire belt, which could be approximated by a pressurised thin cylindrical shell having free boundaries. Then the mode shapes and resonance frequencies of the belt are calculated as functions of the material and geometrical properties of the shell and the speed of the shell rotation. The resonance frequencies and the mode shapes of the free rotating cylindrical shell could be used to form a foundation for the forced vibration response and thus offer a possibility to couple the free tire belt to models of the sidewall and the air cavity inside the tire using, for example, mobility-impedance based methods.
