Organizations with changing structures: how to control?

Purpose The purpose of this paper is to describe management control systems (MCS) as a package within a festival, as it examines managerial use of management controls over time. Moreover, this study discusses the relation of controls to flexibility and decentralization of organizations which have to deal with constraints such as short development periods, individualization of services/products and resource scarcity. The research thus introduces the elements of time and intensity of use of controls in a time-dependent scenario. Design/methodology/approach This descriptive case study utilizes interviews, observations, document analysis and other tools of qualitative research. Findings This paper reveals that single management controls used by managers configure MCS as a package. These controls are utilized with different intensity throughout the year based on activities that are planned or expected to happen. Such use of controls provides needed flexibility for the organization in which the structure is changing over a short period (one year). Research limitations/implications The single unit subjective analysis that was employed does not allow for generalized results and comparison. Originality/value This rich empirical study informs practitioners on how to tackle daily festival challenges. Moreover, it brings theoretical understanding of management controls as a package in real-life context.

Host stage preference and parasitism behaviour of Aenasius bambawalei an encyrtid parasitoid of Phenacoccus solenopsis

ABSTRACTIn Pakistan, the cotton mealybug, Phenacoccus solenopsis Tinsley (Sternorrhyncha (Homoptera): Pseudococcidae), is a serious pest of many cultivated plants. A parasitoid, Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae), is associated with P. solenopsis. In order to mass rear A. bambawalei for a biological control programme, it is important to investigate the parasitoid’s host stage preference and its parasitism behaviour for P. solenopsis in order to optimise production. The present study showed that under both choice and no-choice conditions, the parasitoid preferred third instar and pre-reproductive host stage mealybugs for parasitism. Parasitoid larva developing inside the host exhibited a greater longevity, shorter developmental period and longer body size in these preferred host stages. Our study also confirmed that A. bambawalei showed no attraction to male mealybugs and no host feeding on any host stage was recorded. The ability of the parasitoid to effectively discriminate between suitable and non-suitable stages means that it is feasible to rear it on a mixed population.

Fundamental Properties of One-Dimensional Zinc Oxide Nanomaterials and Implementations in Various Detection Modes of Enhanced Biosensing.

Recent bioapplications of one-dimensional (1D) zinc oxide (ZnO) nanomaterials, despite the short development period, have shown promising signs as new sensors and assay platforms offering exquisite biomolecular sensitivity and selectivity. The incorporation of 1D ZnO nanomaterials has proven beneficial to various modes of biodetection owing to their inherent properties. The more widely explored electrochemical and electrical approaches tend to capitalize on the reduced physical dimensionality, yielding a high surface-to-volume ratio, as well as on the electrical properties of ZnO. The newer development of the use of 1D ZnO nanomaterials in fluorescence-based biodetection exploits the innate optical property of their high anisotropy. This review considers stimulating research advances made to identify and understand fundamental properties of 1D ZnO nanomaterials, and examines various biosensing modes utilizing them, while focusing on the unique optical properties of individual and ensembles of 1D ZnO nanomaterials specifically pertaining to their bio-optical applications in simple and complex fluorescence assays.

신뢰성 수명예측 도구 Sherlock을 이용한 큐브위성용 임무보드의 고장 메커니즘별 수명예측

극초소형 위성으로 분류되는 큐브위성의 경우, 저가/단기간 개발목표 충족을 위해 일반적으로 진동 및 열 환경 규격을 만족하는 상용부품을 선정하여 제작하고 최소한의 검증시험을 통해 발사 및 궤도 운용을 실시한다. 하지만 제한된 회수로 지상에서 실시된 환경시험만으로 장시간에 걸친 궤도상 열진공과 같은 물리적 부하 환경에 노출된 임무보드의 신뢰성을 보장할 수 없다. 본 논문에서는 현재 자동차 분야에서 탑재 전자기기 신뢰도 예측에 폭넓게 활용중인 신뢰성 수명예측 상용도구인 Sherlock을 적용하여 큐브위성용으로 제작된 전자보드를 대상으로 발사 및 궤도환경에서의 고장 메커니즘 별 수명예측 및 임무기간동안의 신뢰도를 분석하였다. A cubesat classified as a pico-satellite typically uses commercial-grade components that satisfy the vibration and thermal environmental specifications and goes into mission orbit even after undergoing minimum environment tests due to their lower cost and short development period. However, its reliability exposed to the physical environment such as on-orbit thermal vacuum for long periods cannot be assured under minimum tests criterion. In this paper, we have analysed the reliability and life prediction of the failure mechanisms of the cubesat mission board during its service life under the launch and on-orbit environment by using the sherlock software which has been widely used in automobile fields to predict the reliability of electronic devices.

Mapping and candidate gene analysis for a new top spikelet abortion mutant in rice

AbstractGrain numbers is one of the determinations for rice yield and directly associated with spikelet numbers per panicle and its normal development. Lots of genes responsible for spikelet numbers and spikelet early development have been identified, but the molecular information about the spikelet development at later development is still limited. Here, we isolated a rice spikelet abnormal development mutant, which shows degenerated spikelet at the top panicle and named aborted top spikelet mutant 1(Ats1). The spikelets derived from the middle and bottom branches per panicle of Ats1 show normal development with those of wild type. However, a large number of branches and spikelets with arrested development were often observed only on apex panicle. The abnormality did not appear until the stage In8 when rachises elongate rapidly and reproductive organs get mature, based on observations through SEM analysis. The aborted spikelet could develop the complete floral organs with a pair of rudimentary glume, a pair of empty glume, two lodicule, six stamens and one carpel. But all these floral organs did not develop maturity. Genetic analysis on two F2 populations indicated that the Ats1 was controlled by a single dominant gene. By using bulked segregant analysis of F2 population developed from Ats1 crossing with Songjing6, ATS1 was mapped on chromosome 8 between RM3819 and RM5556. Then, the fine mapping was performed with 1078 F2 population developed from Ats1 and IR36. The ATS1 locus was finely mapped in an 85.7 kb region between RM22448 and STS8‐2 with 8 genes according to the rice annotation project database. Sequence analysis of the candidate genes within the delimited region of the Ats1 and Akihikari showed two‐nucleotide changes, including single‐nucleotide substitutions corresponding to an amino acid substitution from asparagine to lysine acid in exons 3 and a 1‐bp deletion resulting in a premature stop codon in exon 22 at the candidate gene, LOC_Os08g06480. A cleaved amplified polymorphic sequence (CAPS) marker, CAPS‐ats1, was developed from the 1‐bp deletion site. The complete cosegregation of the CAPS genotypes with the matching phenotypes were observed in the F2 populations. This suggested that Os08g06480 is most likely the ATS1 gene. These results will provide more information for better understanding of the molecular mechanism governing top spikelet abortion within a short developmental period.

Comparative biology and fertility parameters of two spotted spider mite, Tetranychus urticae Koch. on different grapevine varieties

The influence of the four grapevine varieties 'Thompson Seedless', 'Manjri Naveen', 'Gulabi' and 'Bangalore Blue' on fitness, development and reproductive characteristics of the two spotted spider mite, Tetranychus urticae was studied. The biology of two spotted spider mites consisted of egg, larvae, protonymph, deutonymph and adult stages. The total duration from egg to adult was found to be the least in 'Thompson Seedless' (16.2 days) followed by ''Manjri Naveen' (17.2 days), 'Gulabi' (17.2 days) and maximum in 'Bangalore Blue' (32.2 days). The survival rate of life stages of mites was found to be lower in 'Bangalore Blue'. The higher values of net reproductive rate, intrinsic rate of increase, finite rate of increase the shortest mean generation time was observed in 'Thompson Seedless' followed by 'Gulabi', 'Manjri Naveen' and 'Bangalore Blue'. The results suggested that 'Thompson Seedless' was the most suitable cultivar with higher survival rate of life stages of mites, shortest development period, higher value intrinsic rate of increase and fecundity whereas 'Bangalore Blue' was the least suitable cultivar because of the lowest intrinsic rate of increase, longest development period, lower survival rate of life stages of mites.

Biological Parameters of Euschistus heros (F.) (Heteroptera: Pentatomidae) and its Susceptibility to Entomopathogenic Fungi When Fed on Different Diets

The effects of six diets on biological parameters of Euschistus heros (F.) (Heteroptera: Pentatomidae) and its susceptibility to entomopathogenic fungi Beauveria bassiana (Bb) and Metarhizium anisopliae (Ma) were studied. The diets included a standard diet (bean pods+soybeans, peanuts and sunflower) and diets in which the bean pods were combined with only one type of grain, either soybean, peanut, sunflower, pea or sesame seeds. The best performance was that of insects fed on standard diet, which had the shortest development period and 49.5% of egg-to-adult viability. The insects fed the pea diet exhibited less than 30% viability and 11% of adults had wing deformations. The finite rate of increase values for the treatment groups were: standard: 1.091; soybean: 1.077; peanut: 1.071; sunflower: 1.076; pea: 1.058; and sesame: 1.065. The susceptibility to Ma (55%) was greater than Bb (40%) only for insects fed on the sesame diet. Considering the effects of diet on susceptibility to both fungal species comparatively among the diet-treatment groups, the stink bugs fed the restrictive diets were more susceptible compared with those fed the standard diet. We concluded that diet composition affects the biological parameters of E. heros and differentially affects their susceptibility to Bb and Ma fungi.

The Effect of Combinations of Food Insects for Continuous Rearing of the Wing Polymorphic Water Strider Limnogonus Fossarum fossarum (Hemiptera: Gerridae).

The water strider Limnogonus fossarum fossarum (F.) (Hemiptera: Gerridae) shows a macropterous, micropterous, and apterous polymorphism. Although a long photoperiod condition induces winged morphs, preliminary studies have revealed that crossing between winged morphs increased the proportion of macropterous individuals, suggesting that the genetic factors also affect wing-morph determination in this species. Assessing the genetic backgrounds of wing polymorphism requires constant and repeatable methods for rearing. This study attempts to establish a continuous rearing method for L. f. fossarum under constant diet conditions. Initially, we maintain the water striders with two Drosophila species as a food, but viability until adulthood is less than 20%. We then add the storage pest Plodia interpunctella (Hübner), which are readily reared in the laboratory, to the diets. As a result, nymphs fed on P. interpunctella (even only until the second instar) show significantly higher viability and shorter developmental period than nymphs fed on Drosophila alone. Moreover, feeding on D. melanogaster (Meigen) reared on cholesterol-enriched medium instead of a normal medium significantly increases viability in the next generation. This means that only the two food-insect species are enough for establishing a substantial number of individuals in segregating generations (F2 and backcross), limiting DNA and RNA contaminations from food insects with genome information. Thus, the present rearing method opens the way to elucidating the genetic backgrounds of the wing polymorphism in L. f. fossarum.

Trajectories of gambling problems from mid-adolescence to age 30 in a general population cohort.

Studies of gambling starting before adulthood in the general population are either cross-sectional, based on the stability of these behaviors between 2 time points, or cover a short developmental period. The present study aimed at investigating the developmental trajectories of gambling problems across 3 key periods of development, mid-adolescence, early adulthood, and age 30, in a mixed-gender cohort from the general population. Using a semiparametric mixture model, trajectories were computed based on self-reports collected at ages 15 (N = 1,882), 22 (N = 1,785), and 30 (N = 1,358). Two distinct trajectories were identified: 1 trajectory including males and females who were unlikely to have experienced gambling problems across the 15-year period, and 1 trajectory including participants likely to have experienced at least 1 problem over the last 12 months at each time of assessment. Participants following a high trajectory were predominantly male, participated frequently in 3 to 4 different gambling activities, and were more likely to report substance use and problems related to their alcohol and drug consumption at age 30. Thus, gambling problems in the general population are already observable at age 15 in a small group of individuals, who maintain some level of these problems through early adulthood, before moderately but significantly desisting by age 30, while also experiencing other addictive behaviors and related problems.

A Study on the Influence of Use of Web 2.0 Collaboration Tool Reflecting Agile Practice on the Evaluation of OS Project

For the agile development methodology that repeats the frequent releases and the short development periods, there are some value practices that we have to keep. Among them, three typical practices were selected: use of Web 2.0 collaboration tool, adoption of the test driven development (TDD) and refactoring. The agile practice that forces the communication between team members was defined with the use of Web 2.0 collaboration tool. When this is applied to the development method of open-source projects which are dispersed geographically, temporally and culturally, it is expected to raise the satisfaction of OS project users and to contribute the maturity of community. It was applied to the study models that were drawn out from the precedent studies. Today, OS project users are adopting diverse tools for the online communication. But the degree of communication that is emphasized in the agile methodology can be satisfied only with the use of two-way, open and communicable tools reflecting the characteristics of Web 2.0 rather than with the conventional one-way information transmitting tool. In this situation, it was examined how the conventional and the improved tools have influence on the users’ satisfaction. This paper is focusing on the communication factor among 3 factors.

Reliability Estimation from Linear Degradation and Failure Time Data With Competing Risks Under a Step-Stress Accelerated Degradation Test

The accelerated degradation test (ADT) has become critical for product reliability assessment. In performing the ADT for newly developed products, a constant-stress ADT may be impractical or sometimes impossible where the available size of testing units and the testing duration are heavily bounded to meet the short development period of the products. As an alternative, a step-stress accelerated degradation test (SSADT) can be a useful tool for satisfying the test limitation, and for making up for uncertainty in selecting appropriate levels of stress. Occasionally, the elevated stress under SSADT not only accelerates the performance degradation of products, but it may also expedite traumatic failures. This paper proposes a modeling approach to simultaneously analyze linear degradation data and traumatic failures with competing risks in an SSADT experiment. Under the modeling approach, a cumulative exposure model is considered. The failure rate corresponding to each failure mode is described as a function of the degradation level at the moment of failure. No parametric assumptions are made regarding the failure-time distribution to extend the proposed method to more general cases. We derive maximum likelihood estimates of the model parameters, then estimate failure rates and product reliability based on the degradation level to failure. Asymptotic properties of the maximum likelihood estimates are also discussed. The proposed model is applied to accelerated degradation data from plastic substrate active matrix light-emitting diodes (AMOLEDs), along with sensitivity analysis.

Active Sites for Oxygen Reduction Reaction in Tantalum Oxynitride Nanoparticles on Multi-Walled Carbon Nanotubes Synthesized Using Ammonia Pyrolysis

Group 4 or group 5 metal oxide compounds have attracted attention as an oxygen reduction reaction (ORR) catalyst in acidic media where they displayed excellent stability.1 Because of their short development period, discussions on the active sites in these oxide compounds are lacking compared with those in other non-platinum group metal catalysts, e.g., compounds of iron/cobalt, nitrogen and carbon and these metal-free nitrogen-doped carbons (CN x ). Besides, recent progress in the activity of oxide compounds has attracted suspicious eyes for the active sites as it was achieved primarily by changing the oxide precursor from the metal carbonitrides to oxy-metal phathalocyanine, which could produce both oxides and CN x . We recently synthesized oxide catalyst containing one of the group 5 metals, tantalum via the decomposition of oxy-tantalum phthalocyanine (TaOPc) in melted salicylic acid powders to control the size of tantalum oxide (TaO x ) particles to the order of nanometers and to connect TaO x to a support, multi-walled carbon nanotube (MWCNT). Graphitic carbons built from TaOPc successfully provided conductive paths to TaO x insulation particles.2 The activity of TaO x -MWCNT was far higher than tantalum-free phthalocyanine-adsorbed MWCNTs after pyrolysis under identical conditions. This work thus demonstrated that the active site was TaO x , not CN x species originating from TaOPc. Substitution of oxygen atoms in these oxide catalysts by nitrogen is an excellent technique to stabilize oxygen defects which have been acknowledged to be an ORR active sites. The nitrogen-doping has often been performed after oxide particles were supported on carbon supports3 or simaltaneously.4 Therefore, ORR activity of CN x species synthesized by the nitrogen doping process and that of metal-oxynitrides have been carefully compared to discuss active sites.3,4 In any of these previous works,3,4 the oxynitrides showed higher activity than CN x . In this study, two different TaO x -MWCNT catalysts were synthesized by changing the preparation of TaOPc precursors. Then they were pyrolyzed under ammonia gas at various temperatures to obtain TaO x N y -MWCNTs. The ORR activity of these two catalyst types in acidic media have been carefully compared to clarify the active sites. For the first time, slightly oxidized Ta3N5was proposed to be an ORR active site. References (1) A. Ishihara, Y. Ohgi, K. Matsuzawa, S. Mitsushima and K. Ota, Electrochim. Acta, 55, 8005 (2010).

PHOTOSYNTHETIC PIGMENTS AND ONTOGENESIS OF EQUISETUM ARVENSE L.

Specimens of now living type Equisetum are characterised by very large morphological plasticity, are of interest in pharmacognosy, are the object of studies in search of effective means for fighting rhizome weeds and as indicator of acidic soils. However, problems of field horsetail physiology, related, in particular, to features of its ontogenesis and ability to efficiently accumulate vegetative mass and spare nutrient substances in a short period of time have not been finally clarified.The aim of the present work is to study chlorophyll content in different organs of field horsetail in ontogenesis, as well as features of ultrastructure of its photosensitising tissue.Phenological observations of plants were carried out by generally accepted methods in period from March to August of 2009-2012.Tendency of chlorophyll a and b content increase in branches and internodes of assimilating shoots in successive passing of development phases by plants was established.Relatively high content of photosynthetic pigments in lower branches of assimilating shoots of field horsetail (phase 40 cm) is conditioned by presence of completely formed photosynthetic apparatus and indicates maximal assimilation ability of plants at given stage of ontogenesis.Ability of field horsetail to accumulate vegetative mass and spare nutrient substances in short period of active development can be provided by structure (accumulation of highly differentiated chloroplasts) and physiological condition (content of pigments in branches and internodes) of photosynthetic apparatus of its assimilating shoots.

Influence of different types of Phyllostachys pubescens (Poales: Poaceae) leaves on population parameters of Pantana phyllostachysae (Lepidoptera: Lymantriidae) and parasitic effects of Beauveria bassiana (Moniliales: Moniliaceae).

We found that Pantana phyllostachysae, a dangerous pest of moso bamboo (Phyllostachys pubescens), showed differences in growth and development after feeding on diverse types of moso bamboo leaves. The mortality rate of Pa. phyllostachysae due to Beauveria bassiana, an entomopathogenic fungus, was also affected by the varied larval diet. Larval and pupal developmental duration of Pa. phyllostachysae was longer when feeding on “off-year” bamboo leaves. Pupal weight and adult fertility were higher when feeding on “on-year” bamboo leaves. Mortality due to B. bassiana was significantly lower in larvae fed on on-year bamboo leaves than in larvae fed on off-year bamboo leaves. Larvae fed on new bamboo leaves had a shorter development period and higher survival rate than those fed on off-year bamboo leaves. However, mixed feed (mixture of new, on-year, and off-year bamboo leaves) decreased the egg production of Pa. phyllostachysae. After infection by the second generation of B. bassiana, the survival time of Pa. phyllostachysae fed on mixed feed increased significantly compared with the first generation. We also fed Pa. phyllostachysae different proportion of new bamboo leaves in mixed feed to simulate natural conditions. We found that increasing the proportion of new bamboo leaves in the food promoted pupal development and increased egg production; it also increased the resistance of larvae to the first generation of B. bassiana. The pathogenicity of the second generation of B. bassiana declined in all mixed feed treatments.

Preterm Birth Complications On Oro-Dental Structures: An Updated Review

ABSTRACT Preterm birth is the birth of a baby of less than 37 weeks gestational age. The cause of preterm birth is in many situations elusive and unknown. Premature infants have a short prenatal development period and are at greater risk for short and long term complications, including disabilities and impediments in growth and mental development. The prevalence of oral defects in the deciduous and permanent dentition has been reported to be higher in premature infants. Premature birth can cause enamel defects such as quantitative loss of enamel (hypoplasia), qualitative change in the translucence (opacity) of the enamel, or a combination of both. Other dental defects in preterm babies include notching of the alveolar ridge, palatal grooving, high arched palate, dental crossbite and palatal asymmetry. Moreover, delayed eruption/maturation and developmental defects of both the primary and permanent dentitions have also been reported. With the introduction of intensive medical care including the increased use of antenatal corticosteroids and the recent routine administration of surfactant replacement therapy, survival of prematurely born infants has improved markedly. However, the significant progress has been made in the care of premature infants but not in reducing the prevalence of preterm birth, making the reduction of preterm birth a challenging proposition.

Preterm Birth: A Primary Etiological Factor for Delayed Oral Growth and Development.

ABSTRACTPreterm and low birthweight children comprise approximately 6% of all live births. It is now a well-known fact that premature children experience many oral complications associated with their preterm births. Prematurely born infants have a short prenatal development period and they are prone to many serious medical problems during the neonatal period, which may affect the development of oral tissues. Adverse perinatal factors, premature birth and exceptional early adaptation to extra-uterine life and functional activity may influence dental occlusal development and symmetry in the jaws. Thus, the goal of the present paper is to elucidate further the effect of preterm birth on the development of the dentition.How to cite this article: Zaidi I, Thayath MN, Singh S, Sinha A.

C++ Builder and Inter Base Based Design and Realization of Intelligent Monitoring Control System of HV Static Reactive Compensator

SVC is a dynamic reactive compensator based on switching type HV electrical and electronic devices, well recognized as an effective means of resolving power quality problems. SVC is complex in structure, consisting of TCR valve sets, FC filter channel, etc. In particular, TCR valve set adopts thyristor serial connecting technology, and over 100 thyristors are adopted, which requires real-time status of devices in SVC to be monitored and uploaded, and even failures to be recorded. Therefore, the monitoring software becomes an important part in ensuring SVC safe operation. Combined with actual cases, this paper introduces a technology of using C++ Builder and Inter Base to design the static reactive compensator monitoring software. The user interface is elegant, with short development period, highly transplantable, and easily modified.
