Applying the dynamic capabilities framework in the case of a large public construction client

Abstract Public clients in the construction sector face a number of challenges in designing, procuring and managing major construction projects. The client’s role in bringing about project delivery has more recently been emphasized, particularly with respect to developing capabilities that facilitate the coordinating of projects through its different phases. In line with these developments, this paper sets out to examine the management of capabilities in a client organization through the lens of the dynamic capabilities framework. In particular, what is investigated is how the client organization senses, seizes and transforms opportunities. In pursuit of this objective, an exploratory case study approach is adopted which examines one of Sweden’s largest public client organizations. The study explores the concept of dynamic capabilities and its applicability to the public construction context. Although the usefulness of dynamic capabilities as an interpretive framework is recognized, it is suggested that the concept of dynamic capabilities is inadequate for addressing the specific context in which public client organizations operate. Particularly with respect to the project-based characteristic of these organizations and the difficulty in framing what constitutes “competitive advantage” for public organizations.
Chapter 3 Oral and Periodontal Diseases in Consanguineous Marriages

Periodontitis is defined as an inflammatory disease of supporting tissues of teeth characterized by progressive destruction of the periodontal ligament and alveolar bone. Periodontal manifestations of these genetic disorders or syndromes, such as familial and cyclic neutropenias, granulomatous disease, agranulocytosis, Langerhans’ cell disease, glycogen storage disease, hypophosphatasia, leucocyte adhesion deficiency, and Papillon‐Lefèvre, Chédiak‐Higashi, Cohen, Ehlers‐Danlos, Marfan, Down, Haim‐Munk, and Kindlers syndromes, imitate some types of periodontal diseases. Most of these syndromes have autosomal‐recessive characterization and can be seen commonly in consanguineous marriages. Therefore, consanguineous marriages have generally been accepted as having important detrimental effects on offspring. There is a lot of genetic research about consanguineous marriage and its detrimental effects on offspring. Although consanguineous marriages are common in the world, the relationship with oral and periodontal diseases has not been thoroughly investigated. We do not have enough of an understanding of the effects of consanguineous marriage on oral and periodontal diseases. In this chapter, previous studies in the literature related to this subject will be investigated and evaluated, and then this research will be related to oral and periodontal diseases. Therefore, this chapter will guide further research. The aim of this chapter is to show the relation between consanguineous marriages and oral‐periodontal diseases.
Evaluation of Mutagenic Effects of Chronic Renal Disease and Hemodialysis

The present study aimed to evaluate the mutagenic effects of chronic renal disease (CRD) and haemodialysis (HD) using the mutagenic test known as the micronucleus assay The study involved 97 individuals, including 32 CRD patients on HD, 34 CRD patients not on HD and 31 controls. Buccal smears were examined with a light microscope at 400, and cells showing micronuclei, binucleated nuclei, “broken egg” nuclei, pyknosis, karyorrhexis and karyolysis were counted in 2000 cells for each participant. Our main results demonstrate that the clastogenicity indicators micronuclei, binucleated cells, broken egg cells, sum of binucleated plus broken egg cells and sum of pyknosis plus karyorrhexis were statistically significant higher in the CRD and HD group compared to the CRD and non-HD groups and the control group (p=0.0001). Males had more binucleated cells (p=0.002) and sum of binucleated plus broken egg cells (p=0.0001). Those with a family history of genetic disease had more binucleated cells (p=0.002). Those on HD who did not consume wine showed more micronuclei (p=0.042). Consumers of distilled alcoholic beverages had more karyolysis (p=0.038). Those not on HD but exposed to chemical agents had more karyolysis (p=0.041). Controls who drank wine had a lower sum of binucleated plus broken egg ells (p=0.050). Ex-smokers had more broken egg cells (p=0.006). We conclude that the CRD and HD combined with occupational and genetic factors and certain lifestyle habits promote the occurrence and increase of micronuclei and other nuclear changes, possibly able to contribute to the emergence of renal cancer.
Epidemiological survey on esca disease in Umbria, central Italy.

Esca is a grapevine disease occurring in all vine-growing areas, including Italy. Multiple fungi that have been associated with esca spread by releasing aerial spores that infect pruning cuts and wounds. The aim of the study was to determine the occurrence of the most common fungi associated with esca in Umbria (central Italy) and to fi nd under what weather conditions they release their spores. Disease incidence was also determined in the summers of 2006 and 2007 on ten grapevine cultivars (Cabernet Sauvignon, Grechetto, Sangiovese, Trebbiano toscano, Pinot bianco, Trebbiano spoletino, Ciliegiolo, Montepulciano, Chardonnay and Merlot) growing together in the same vineyard. Visual inspection of the vines showed that all cultivars were susceptible to esca, but that esca incidence differed in intensity between cultivars. In both years, esca incidence was higher with Cabernet Sauvignon, Sangiovese and Trebbiano toscano, and lower with Montepulciano and Merlot. Disease incidence went up in summer. Phaeomoniella chlamydospora was isolated from vine samples showing dark wood streaking, and Fomitiporia mediterranea from samples with white rot, confi rming that these fungi are involved in esca. Spores of P. chlamydospora were trapped from March to December 2007. Spore release was affected by weather parameters (rain and temperature).
The Effect of Carob Pods and Fig Fruits Ether Extracts against Lead Induced Hematological and Biochemical Changes in Oreochromis niloticus

The current study aimed to investigate the possible effect of Ceratonia siliqua (carob) pods and Ficus carica (fig) fruits ether extracts against lead toxicity on hematological, biochemical parameters, growth performance and mortality % in Nile Tilapia ( Oreochromis niloticus ). One hundred and forty fish were divided into 7 groups. The first group was left as a control and fed a control diet, while, the second and third groups were exposed to 1/2 96 h LC 50 (77.5 mg/L) and 1/4 96 hLC 50 (38.7 mg/L) of Lead (Pb), respectively and provided with a control diet. The fourth and fifth groups were exposed to 1/2 96 h LC 50 and 1/4 96 h LC 50 of Pb, respectively and fed diet with 600 mg carob extract/kg diet. The sixth and seventh group were exposed to 1/2 96 h LC 50 and 1/4 96 h LC 50 of Pb, respectively and provided with diet contain 600 mg fig extract/kg diet. The hematological, biochemical parameters and growth performance was significantly decreased after exposure to 1/2 96 h LC 50 and 1/4 96 hLC 50 of Pb for 30, 60 and 90 days, while plasma glucose and mortality % were increased significantly. There were no significant changes in RBCs, Hb and PCV of O. niloticus exposed to 1/2 96 h LC 50 and 1/4 96 h LC 50 of Pb that fed diet enriched with carob extract 600 mg/kg diet for 90 days. The fish exposed to 1/2 96 h LC 50 and 1/4 96 h LC 50 of Pb and fed diet enriched with 600 mg/kg diet carob or fig for 90 days revealed no significant changes in plasma albumin, total protein, glucose and growth parameters with a reduction of mortality %. The current study highlighted the importance of carob and fig ether extract in the protection of Nile tilapia against the lead acetate toxicity.
Representing the Effects of Oligopolistic Competition on Risk-Neutral Prices in Power Markets

Forward transactions are becoming increasingly important in most of electricity markets. In this view, this paper develops a methodology able to capture the complexities of power markets and incorporate them into the framework of risk-neutral probabilities. This is done by the statement of a model that split up the power price dynamics into two different components: on the one hand, a component aimed at representing costs and market power, which will be based on a static, non-cooperative game; on the other, a component representing short-term deviations from the static model.
IMPROVEMENT OF JENSEN–STEFFENSEN’S INEQUALITY FOR SUPERQUADRATIC FUNCTIONS

In this paper, improvements for superquadratic functions of Jensen- Steensen's and related inequalities are discussed. For superquadratic func- tions which are not convex we get inequalities analog to Jensen-Steensen' s inequality for convex functions. For superquadratic functions which are con- vex (including many useful functions), we get improvements and extensions of Jensen-Steensen' s inequality and related inequalities.
AGRICULTURAL EFFICIENCY OF SMALLHOLDER FARMERS IN EASTERN CAPE PROVINCE OF SOUTH AFRICA

Millions of people in rural South Africa depend on smallholder subsistence agriculture as their major source of livelihood. However, the sector is underdeveloped, stagnant and bound to decline, slowing down development and hindering poverty alleviation. Therefore, there is a need to understand the determinants of production efficiency for increased food security and poverty reduction. This paper examined the allocative and technical efficiencies and determinants of technical efficiency of smallholder farmers at Qamata and Tyefu irrigation scheme. The paper employed the Cobb-Douglas production function and stochastic frontier analysis to estimate both allocative and technical efficiencies of smallholders. The findings of this study indicated that farmers were allocatively inefficient, underutilizing seeds, pesticides and herbicides and incurred higher costs in fertilizer use. Smallholder farmers were, however, technically efficient at approximately 98.8% and determinants of this efficiency included household size, farming experience, use of agro-chemicals, off-farm income, and gross margins earned from maize, and household commercialization level. Proposed key policy options that must be considered to address the inefficiencies include improved quality of extension services, provision of trainings in farm business management skills, and policies that promote investment incentives for agroinput/output small-scale industries.
Effect of Irrigation Water Deficit on Antioxidant Activity and Yield of Some Sunflower Hybrids

Sunflower (Helianthus annuus L.) is one of the most important oil-producing plants that it can tolerate short periods of water deficit (WD). The objective of this study was to evaluate the effects of water stress on the physiological and agronomic characteristics of four sunflower hybrids. A two-year field experiment was carried out using a randomized complete block design with four replications and a split plot arrangement. The irrigation treatments were applied based on 60 mm (full-irrigated), 120 mm (moderate water deficit) and 180 mm (extreme water deficit) of evaporation from the ‘class A’ pan evaporation. The results showed that water deficit, compare to full-irrigated, significantly increased the activity of all antioxidant enzymes in leaves such as Superoxide dismutase (SOD), Glutathione peroxidase (GPX), Glutathione reductase (GR) and Catalase (CAT). The correlation results showed that the seeds number per head was main yield components associated to seed yield when sunflower plants were grown under the full-irrigated and extreme water deficit. The results showed that the Euroflor and Allestar hybrids had highest seed yield in full and limited irrigation condition, respectively. The correlation results showed that there was a high, positive and significant correlation among seed yield and CAT in water irrigation deficit condition. Moreover, the GPX and CAT content can be used as a drought tolerance index to selection tolerant genotypes under moderate and extreme water deficit conditions.
Labor Misallocation and Mass Mobilization: Russian Agriculture during the Great War

Abstract We exploit a quasi-natural experiment of military draftees in Russia during World War I to examine the effects of a massive, negative labor shock on agricultural production. Employing a novel district-level panel data set, we find that mass mobilization produces a dramatic decrease in cultivated area. Surprisingly, farms with communal land tenure exhibit greater resilience to the labor shock than private farms. The resilience stems from peasants reallocating labor in favor of the commune because of the increased attractiveness of its nonmarket access to land and social insurance. Our results support an institutional explanation of factor misallocation in agriculture.
Laterally Coupled Quartz Resonators

By placing two pairs of electrodes onto a single plate of an AT-cut quartz crystal, one can obtain a device with two separate resonating units on one and the same quartz blank. Energy trapping confines the area of oscillation to a region around the individual electrodes. If the two resonators are spaced close enough to each other, the oscillating regions slightly overlap and coupling occurs. The coupling can be modeled with an equivalent circuit based on two Butterworth−van Dyke circuits connected across a complex resistance providing the coupling. For sufficiently decoupled oscillators, one electrode pair can serve as a reference resonator for microbalance applications. The reference resonator experiences the same environment as the sensing resonator and can therefore be used to measure and subtract effects of temperature, viscosity, and hydrostatic pressure of the ambient medium.
Effects of Addition of Electrolyte and Ascorbic Acid in Feed during Heat Stress in Buffaloes

The ameliorative effect of salts and ascorbic acid polyphosphate supplementation on heat stress was studied in buffaloes. Adult buffaloes of either sex were randomly divided into 2 groups of 4 animals each. Group I served as control and Group II was supplemented with sodium bicarbonate, potassium carbonate and ascorbic acid polyphosphate. All the animals were exposed to two conditions of temperature and humidity: hot-dry and hot-humid in a psychrometric chamber for 4 h daily for 10 days. Blood was collected on day 1, 5 and 10 of treatment. The activities of catalase and superoxide dismutase (SOD), concentrations of serum glutathione (GSH), cortisol, sodium, potassium, and chloride and lipid peroxidation were estimated in serum. Lymphocyte proliferation was assessed in blood. The activities of catalase and SOD, serum concentration of GSH, sodium, potassium and chloride decreased while lipid peroxidation and serum cortisol increased in both groups when subjected to heat stress. Dietary supplementation resulted in further decreasing of the enzyme activities but increasing of the serum concentrations of GSH, sodium, potassium and chloride. Lipid peroxidation and serum cortisol increased in the supplemented group in both types of stress. Dietary supplementation caused an increase in lymphoproliferative response to con A. Thus, supplementation of ascorbate in addition to electrolytes relieves the animals of oxidative stress and boosts cell mediated immunity.
On the elastic energy invariance of crystal twins

An analysis by Zanzotto (1992, 1996) showed that, if crystal twinning is considered as a material symmetry operation, the symmetry groups of many crystals that form twins correspond to the unimodular group, which is the symmetry group of elastic fluids. It is therefore evident that an elastic modelling based on an elastic energy that includes any possible combination of twin system activation must fail. However, one may try to construct an elastic energy which includes only the stressfree configurations of the parent and the first order twins. It is known that, even under this restriction, many twinning modes exhibit an elastic energy invariance, which renders them indistinguishable in terms of the elastic energy. In this article, it is demonstrated that this energy invariance holds for all compound twins. The implications of the latter are discussed. It is suggested to distinguish between crystallographically equivalent and crystallographically distinct compound twins, since different implications regarding the elastic energy invariance emerge.
The contribution of export earnings to economic growth of Ethiopia: a trend analysis

Empirically examining the contribution of different macroeconomic variables to economic growth would help the country to formulate conducive policies to foster economic growth in this regard. This study had investigated the contribution of export earnings to economic growth of Ethiopia for the period 1960/61-2011/12 by empirically testing the long run and short run relationship and causality between export and economic growth via another macroeconomic variables, i.e., import using popular time series econometric techniques of co-integration ,vector error correction estimation and Granger causality test and the review of the policies commenced by the different regimes in relation to export. The results from unit root test show that all variables are order one integrated; and Johansen co­ integration shows the existence of long run relations among the variables. Furthermore, the Granger causality test conducted indicates that in the short run there is no causality among variables but in the long run there is bidirectional causality among the three variables, including: GDP, Export and Import. The key finding in this study is that export growth positively and significantly affected economic growth and growth also stimulate export in the long run. This provided support for the adoption of both Export -Led Growth and Growth-Led Export growth strategies in case of Ethiopia. Thus, effort should be directed towards policies that will expand the volume of a country’s exports and at the same time promote the emergence and expansion of domestic industries. 1 St. Mary’s University, P.O.

Optimization of lifetime in sensor networks

We consider the problem proposed by Thales Nederland at the SWI 2012 meeting. Thales Nederland is the Dutch branch of the international Thales Group. The company specializes in designing and producing professional electronics for defence and security applications, such as radar and communication systems. Moreover, Thales Nederland acts as a local point of contact for the complete portfolio of the Thales Group. During the SWI 2012 meeting, on behalf of Thales Nederland, Dr. Maurits de Graaf posed several questions regarding the maximization of the lifetime of a wireless sensor network. We addressed these questions during the workshop and our most significant results are summarized as follows: We have proven that this lifetime maximization problem, even under the most simple constraints, is NP-complete, so it is not possible to find an algorithm that gives the optimal solution within polynomial time. Furthermore, we have constructed a counterexample to illustrate that the heuristic currently used by Thales can be asymptotically at least logn times worse than the optimal solution. Moreover, we have developed a new heuristic and have illustrated with several numerical examples that it performs better than the heuristic currently used by Thales. Finally, we have formulated the problem as a linear programming problem and used this to quantify how far the heuristic used by Thales is from being optimal.
Petrographic and mineralogical characterisation of fractionated pegmatites culminating in the Nb-Ta-Sn pegmatites of the Gatumba area (western Rwanda)

The Karagwe-Ankole belt in Central Africa hosts numerous rare-metal pegmatites and Sn-W mineralised quartz veins, which are related to the granite generation that formed at 986 ± 10 Ma, i.e. the G4-granites in Rwanda. This early Neoproterozoic granite generation features in the Gatumba area (western Rwanda) a linkage with a zoned cluster of barren and Nb-Ta-Sn mineralised pegmatites. The most distal pegmatite bodies in this area suffered from intense alkali metasomatism, i.e. widespread growth of albite and white mica. A petrographic and geochemical study has been carried out on the pegmatite bodies in order to determine the petrogenetic evolution of the pegmatite zonation. The compositional variation of schorl and elbaite, sampled along the regional zonation sequence, implies that the zonation can be expressed by 4 zones: a biotite, a two-mica, a muscovite and a mineralised pegmatite zone. Alkali element variations and enrichments in muscovite and K-feldspar along the zonation sequence indicate that the origin and the formation of the different pegmatite zones can be explained by a single path of fractional crystallisation. This substantial chemical differentiation accompanies in the Gatumba pegmatite field the evolution from the G4-granite generation to common pegmatites and eventually rare- element pegmatites.
Functional Polycentrism and Urban Network Development in the Greater South East UK: Evidence from Commuting Patterns, 1981-2001

In contemporary literature on changing urban systems, it is often argued that the traditional central place conceptualisation is outdated and should be replaced by a network view that emphasises the increasing criss-crossing pattern of interdependencies between spatial units. This paper tests for urban network development by looking at commuting patterns in the Greater South East UK. The analysis is based on census commuting interaction data for three points in time during the past three decades (1981, 1991, and 2001). Although the empirical results indicate that the Greater South East UK can still not be characterized as a polycentric urban region or integrated urban network, there is some evidence for urban network development at the local, intra-urban, level as well as a decentralization of the system at the regional, inter-urban, level.
The Interaction of Monetary Policy and Financial Stability: Lessons from the 2007 Crisis

The financial crisis motivated thinking about interaction between financial and monetary stability policies. These policies are more interrelated than previously thought. The purpose of the paper is to develop an analytical framework that analyzes these interactions. We use an overlapping-generations model in which an aggregate financial risk is endogenous. It embeds negative externalities in the perceived risk, and integrates banking into our DSGE model. The results include (i) monetary policy's effectiveness is affected by financial stability policy; (ii) institutional constraints on central bank's lending affect the operation of monetary policy transmission mechanism; (iii) policy makers will conceivably face tradeoffs between price stability and financial stability.
