Exploring the Relationships between Strategy, Innovation, and Management Control Systems: The Roles of Social Networking, Organic Innovative Culture, and Formal Controls
Authors: Chenhall Robert H. , Kallunki Juha-Pekka , Silvola Hanna 
Published: December 2011

ABSTRACT
This paper is concerned with the relationship between strategy, management control systems (MCS), and innovation. MCS are described in terms of a package of controls that is comprised of social networking, organic innovative culture, and formal controls. We develop a path model that proposes that product differentiation is associated with more extensive innovation. It is argued that this association is explained, in part, by paths from product differentiation to the three dimensions of MCS, and then paths from these MCS dimensions to innovation. Using a survey of Russian enterprises we confirm that product differentiation is associated with innovation. Also, product differentiation is associated with each dimension of the MCS. Organic innovative culture and formal controls have direct paths to innovation, while social networking has an effect on innovation by acting indirectly through its connection with organic innovative culture.

AbstractOral health-related quality of life (OHRQoL) is multifaceted and involves many factors. One of them is the use of dental implants. It was the aim of our study to assess whether implant therapy might improve OHRQoL. We consulted patients with at least one Astra Tech implant. Each patient completed oral health questionnaires, which were then statistically evaluated using the Wilcoxon signed-ranks test and Analysis of Covariance from a functional and aesthetic point of view. Differential response on individual scales was assessed using multivariate approach. All twelve marginal Wilcoxon tests showed an overall improvement in OHQoL (α = 0.05). On the aesthetic scale, OHRQoL was found to be associated with marital status, aesthetic reasons for undergoing surgery and number of front teeth replaced by implants. On the functional scale, three covariates were statistically significantly and appeared to have affected the levels of OHRQoL. The most significant explanatory effect was observed for the number of front teeth replaced via implantation, followed by the presence of chewing problems. Marital status was also found to have significantly affected the OHRQoL functional scale. Significant implant-related improvements in both scales were observed in patients with at least one implant in the front dental area.

Prognostic Value of High-Sensitivity C-Reactive Protein and Lipoprotein (a) in Acute Myocardial Infarction Patients Receiving Emergency Percutaneous Coronary InterventionIn order to study the prognostic value of high-sensitivity C-reactive protein (hsCRP) and lipoprotein (a) [Lp(a)] in patients receiving emergency percutaneous coronary intervention (PCI) following acute myocardial infarction (AMI), we retrospectively reviewed 118 patients who received emergency PCI following AMI from January 2007 to April 2010. The plasma levels of hsCRP and Lp(a) were determined. The incidence of cardiovascular events was compared between patients with an elevated hsCRP level and those with a normal hsCRP level and between patients with an elevated Lp(a) level and those with a normal Lp(a) level. Results showed that the incidence of cardiovascular events was 52.9% in the hsCRP-elevated group and 18.2% in the hsCRP-normal group displaying a significant difference (P=0.011). However, the incidence of cardiovascular events was 35.3% in the Lp(a)-elevated group and 46.4% in the Lp(a)-normal group and statistical analysis revealed no significant difference (P=0.733). HsCRP, but not Lp(a), can serve as a prognostic factor for patients receiving emergency PCI following AMI.

TNF-α, HGF and TGF-β1 are Involved in Liver Regeneration Following Partial Hepatectomy Using Portal Vein ArterializationsExperiments on liver regeneration after partial hepatectomy have shown that TNF-α, HGF and TGF-β1 and other cytokines play important roles in the different stages of liver regeneration, however, the effect of portal vein arterialization (PVA) on the expressions of these cytokines during liver regeneration is not clear. Sprague Dawley rats were randomly divided into the PVA group and control groups, and blood was collected for the detection of ALT using an automatic biochemical analyzer. The expressions of TNF-α, HGF and TGF-β1 in liver tissues were detected by quantitative RT-PCR. The ALT levels in both groups in the early period after surgery were significantly higher than those before operation, and gradually returned to normal at 7 days after surgery. At 12 h and 24 h after operation, the TNF-α expression in the PVA group was significantly higher than that in the control group (P<0.05), but no significant difference at 7 days after surgery was observed between the two groups. At 12 h, the HGF expression in the PVA group was similar to that in the control group, but significantly higher than in the control group at 24 h (P<0.05). At 24 h, the TGF-β1 expression in the PVA group was significantly lower than that in the control group (P <0.05), but no significant difference was found at 48 h after surgery between the two groups. The promotive effects on the portal vein arterialization at the early stage of liver regeneration were associated with the changes in the expressions of TNF-α, HGF and TGF-β1.
Towards a case-based computational model for the creative design of electromagnetic devices

Published: December 2011

Towards a case-based computational model for the creative design of electromagnetic devicesIn order to explore creativity in design, a computational model based on Case-Based Reasoning (CBR) (an approach to employing old experiences to solve new problems) and other soft computing techniques from machine learning, is proposed in this paper. The new model is able to address the four challenging issues: generation of a design prototype from incomplete requirements, judgment and improvement of system performance given a sparse initial case base library, extraction of critical features from a given feature space, adaptation of retrieved previous solutions to similar problems for deriving a solution to a given design task. The core principle within this model is that different knowledge from various level cases can be explicitly explored and integrated into a practical design process. In order to demonstrate the practical significance of our presented computational model, a case-based design system for EM devices, which is capable of deriving a new design prototype from a real-world device case base with high dimensionality, has been developed.
Influence of annealing on the mechanical anisotropy of hot pack rolled Ti-6Al-4V sheets
Authors: Satheesh Kumar S. S. , Raghu T. 
Published: December 2011

Abstract
The effect of annealing on the mechanical anisotropy of hot pack rolled Ti-6Al-4V thin sheets was studied. Partial recrystallization/globularization of the deformed microstructure was observed during high temperature annealing of rolled sheets. The room temperature tensile properties obtained along different orientations from rolling direction to transverse direction are used to evaluate the % In Plane Anisotropy (%IPA), and Anisotropic Index (δ). A significant decrease in anisotropy with the increase in annealing temperature was observed. The Knoop hardness based plane stress yield loci were evaluated for the sheets in as-rolled and annealed conditions and the variation in the shape and size of yield loci divulged the decrease in mechanical anisotropy with annealing. The X-ray diffraction scans also revealed the weakening of basal texture qualitatively.
Influence of ammonia concentration on the formation of hollow silica microspheres via polystyrene beads templating

Abstract
The influence of ammonia concentration on the formation of hollow silica microspheres via polystyrene beads templating was investigated. Hollow silica microspheres could only be templated in water – ethanol – ammonia – tetraethyl orthosilicate media with low concentrations of ammonia. It is shown that in template-free media, the aggregation of silica particles decreases with ammonia concentrations. Thus, the aggregation degree of formed silica particles may imply whether a silica forming media is suitable for preparing hollow silica microspheres via polystyrene beads templating. The increase in ammonia promotes spontaneous nucleation and condensation of silica oligomers to form silica particles. The repulsive forces between the particles as well as those between them and templates are relatively large, hindering the assembly of silica primary particles on the templates to form silica shells.
Study of single-walled carbon nanotube dielectrophoresis
Authors: Zhao Bo , Qi Hongxia , Xu Dong , Zhang Yafei 
Published: December 2011

Abstract
Dielectrophoresis was used to align single-walled carbon nanotubes between microelectrodes in deionized water. The influences of solvent concentration, alternating current voltage amplitude and frequency, and direct current electric field on the alignment of nanotube were studied. The results show that the number of deposited carbon nanotubes could be adjusted via the solution concentration and voltage amplitude. Alternating current frequency affects the orientation of the nanotubes. At higher frequency, nanotubes are well assembled between the electrodes. When applying a composite electric field, the direct current component would generate vortex flux at the vicinity of nanotubes, which changes the nanotube alignment.

Object
The use of unilateral dural sinus stent placement in patients with idiopathic intracranial hypertension (IIH) has been described by multiple investigators. To date there is a paucity of information on the angiographic and hemodynamic outcome of these procedures. The object of this study was to define the clinical, angiographic, and hemodynamic outcome of placement of unilateral dural sinus stents to treat intracranial venous hypertension in a subgroup of patients meeting the diagnostic criteria for IIH.

Methods
Eighteen consecutive patients with a clinical diagnosis of IIH were treated with unilateral stent placement in the transverse-sigmoid junction region. All patients had papilledema. All 12 female patients had headaches; 1 of 6 males had headaches previously that disappeared after weight loss. Seventeen patients had elevated opening pressures at lumbar puncture. Twelve patients had opening pressures of 33–55 cm H2O. All patients underwent diagnostic cerebral arteriography that showed venous outflow compromise by filling defects in the transverse-sigmoid junction region. All patients underwent intracranial selective venous pressure measurements across the filling defects. Follow-up arteriography was performed in 16 patients and follow-up venography/venous pressure measurements were performed in 15 patients.

Results
Initial pressure gradients across the filling defects ranged from 10.5 to 39 mm Hg. Nineteen stent procedures were performed in 18 patients. One patient underwent repeat stent placement for hemodynamic failure. Pressure gradients were reduced in every instance and ranged from 0 to 7 mm Hg after stenting. Fifteen of 16 patients in whom ophthalmological follow-up was performed experienced disappearance of papilledema. Follow-up arteriography in 16 patients at 5–99 months (mean 25.3 months, median 18.5 months) showed patency of all stents without in-stent restenosis. Two patients had filling defects immediately above the stent. Four other patients developed transverse sinus narrowing above the stent without filling defects. One of these patients underwent repeat stent placement because of hemodynamic deterioration. Two of the other 3 patients had hemodynamic deterioration with recurrent pressure gradients of 10.5 and 18 mm Hg.

Conclusions
All stents remained patent without restenosis. Stent placement is durable and successfully eliminates papilledema in appropriately selected patients. Continuing hemodynamic success in this series was 80%, and was 87% with repeat stent placement in 1 patient.
Formation et dissolution des familles dans la Slovaquie de la transition
Authors: Seys François-Olivier 
Published: December 2011

En Slovaquie, la fin du régime socialiste, la transition vers l'économie de marché et l'indépendance ont eu non seulement des conséquences sur la société mais aussi sur les dynamiques démographiques et plus particulièrement sur les indicateurs transversaux de formation et de dissolution de la famille. Ainsi, on observe une accélération de la chute de fécondité et de nuptialité, une augmentation de la divortialité. De même, en matière de calendrier, la précocité des événements démographiques héritée d'avant 1989 commence à se retarder avec une augmentation encore timide de l'âge moyen au premier mariage ou à la première maternité. Sur un plan spatial, cela se traduit par un accroissement des disparités internes avec une distinction fondamentale entre l'ouest et l'est du pays. A l'ouest, l'occidentalisation des comportements démographiques est plus précoce et se diffuse actuellement des villes importantes comme Bratislava et Nitra vers les campagnes. A l'est du pays, on observe une résistance beaucoup plus forte du régime démographique hérité de la période socialiste.
Dans l'ensemble, ces disparités correspondent à des disparités sociales, économiques et culturelles comme, par exemple, l'avancée de la transition économique, une opposition entre populations protestantes et catholiques et l'importance des populations tsiganes ayant un comportement démographique original.
Migration agricole et insécurité foncière en pays bwa du Burkina Faso

Agricultural migration and land insecurity in the Bwaba territory of Burkina Faso

The Bwaba territory which has remained under-populated for a long time started to experience a prodigious population growth in the 70s with migratory overflows. The immigrants, mostly Moose peasants from the central and northern parts of Burkina Faso, were attracted by the rich natural potentialities (good rainfall and fertile soils) and by the region being under-populated. The growth of the population, cotton planting and the mechanization of agriculture will increase the need for farming lands to an extent such that access to land has become a major issue in some areas.
The evolution of that issue in the Bwaba territory has now led to land insecurity for the immigrants. This situation which deteriorates the social relationship between the immigrants and the indigenous populations is likely to have an impact on the agricultural productivity which chiefly depends on the immigrants.
The study of the land issue focuses on the social dimension related to land resources. The present study which has been conducted at both regional and local levels shows the global nature of the problem. Demographic and sociological factors, as well as the farming methods and legal matters ought to be taken into consideration in its analysis. The resolution of land insecurity must be included in a regional management policy which takes all the productive capacity of the space into account.

PURPOSE:
To investigate the cell death and inflammatory response to insertion of the KAMRA inlay (AcuFocus Inc) for presbyopia.

METHODS:
Twenty-four rabbits were included in the study. Each rabbit had pockets generated in both corneas with a femtosecond laser. One eye of each rabbit had an inlay inserted into the pocket and the opposite control eye had the pocket dissected. Eight rabbits were studied at 24 hours, 48 hours, or 6 weeks after surgery. Tissue sections were analyzed with TUNEL assay to detect cell death and immunohistochemistry for CD11b to detect monocytes as a marker of inflammation.

RESULTS:

The inlay group had significantly more stromal cell death than the control group at 48 hours after surgery (
P
=.038). At 24 hours and 6 weeks after surgery, no significant difference was noted in stromal cell death between the inlay and control groups. Significantly more CD11b+ cells were noted in the stroma in the inlay group compared to the control group at 24 and 48 hours after surgery (
P
=.025 and
P
=.001, respectively). However, at 6 weeks after surgery, no significant difference in CD11b+ cells was observed between the control and inlay groups (
P
=.05).

CONCLUSIONS:
Although an early increase in stromal cell death and inflammation occurred in eyes that underwent femtosecond laser pocket creation and KAMRA inlay insertion compared to a control group with the pocket only, no significant difference was noted between the inlay and control groups in stromal cell death or inflammation at 6 weeks after surgery.
Unilateral Blaschkoid lichen planus in successive pregnancies
Authors: Kumar Shiva , Okade Rajendra , Abdul Rahman Yasmin 
Published: December 2011

A number of genetic, congenital and acquired dermatoses have been known to follow Blaschko’s lines. A common disorder like lichen planus can very rarely present with pruritic lesions in atypical patterns such as unilateral distribution, painful eruptions and along Blaschko’s lines. Various triggering factors varying from viral infections and vaccinations to trauma have been implicated in lichen planus. We describe a female patient in the second trimester of her second pregnancy who developed unilateral lichen planus along Blaschko’s lines during both pregnancies. No case of lichen planus along Blaschko’s lines recurring during pregnancy is reported so far. Could pregnancy itself be a contributory factor towards onset of lichen planus in this case?
Use of Cultural Themes in Promoting Health among Southeast Asian Refugees
Authors: Frye Barbara A. 
Published: December 2011

Purpose. Vietnamese, Cambodian, and Hmong refugee populations in the United States face serious physical and psychosocial health issues. Literature on these populations is largely descriptive of illnesses and of cultural beliefs or behavior patterns related to illness. There is minimal literature linking beliefs and behaviors to the underlying cultural themes. The purpose of this paper was to search the literature for cultural themes from which culturally relevant health promotion strategies could be designed. Search Methods. Literature was reviewed from the fields of health, social, and political science, history, and Southeast Asian folklore. Search methods included review of 147 writings from library and MEDLINE search and 123 interviews with refugees and key professionals in the field. This manuscript includes 106 selections as well as content from 93 interviews. Findings and Conclusions. From the literature emerged two cultural themes common to these populations, kinship solidarity and the search for equilibrium. The use of these cultural themes as carriers of health messages is suggested. Examples of ways to link the message with the cultural theme are presented, including the use of folklore, recognition of cultural illnesses, and use of cultural knowledge in addressing new situations such as inner city urban survival. Cultural themes are a means of conveying health messages addressing such issues as transition in family structure, depression, and substance abuse.

Purpose. To determine the prevalence of tobacco use among Centers for Disease Control and Prevention (CDC)/Agency for Toxic Substances and Disease Registry (ATSDR) employees and the effect of the smoke-free policy on smoking behavior and air quality at work. Design. A stratified telephone survey of 1181 CDC/ATSDR employees randomly selected from employee rosters. Setting. CDC/ATSDR work sites in Atlanta, Georgia, and other major CDC locations throughout the United States and Puerto Rico. Subjects. Randomly selected employees of CDC/ATSDR1, or about 22% of the total CDC/ATSDR population; 98% of eligible persons selected agreed to participate. Measures. Demographic and smoking history variables, attitudes toward and impact of the smoke-free policy on smoking behavior, and self-report changes in air quality were the measures used. Results. Overall cigarette smoking prevalence was only 11.1%. One percent reported using chewing tobacco, 1.1% reported smoking a pipe, and 1.4% reported smoking cigars. Average self-reported, daily cigarette comsumption significantly decreased after the smoking ban took effect. Overall, 90 % of the employees supported the smoke-free policy, and 80 % of the employees believed that smokers were complying with the smoke-free policy. Most employees believed that the air quality of work areas and nonwork areas (65% and 69%, respectively) had improved since the smoke-free policy was implemented. Conclusions. These findings are consistent with previous evaluations of smoke-free policies and suggest that most employees are generally supportive of workplace smoking restrictions. Such policies can also have a positive impact on smoking behavior and perceived air quality.
Perceptual Comparisons With Laterally Presented Pictures and Environmental Sounds
Authors: Goolkasian Paula , Finkelstein Samantha , Stubblefield Alexandra 
Published: December 2011

Abstract
Two experiments studied perceptual comparisons with cues that vary in one of four ways (picture, sound, spoken word, or printed word) and with targets that are either pictures or environmental sounds. The basic question probed whether modality or differences in format were factors that would influence picture and sound perception. Also of interest were cue effect differences when targets are presented on either the right or left side. Students responded to a same-different reaction time task that entailed matching cue-target pairs to determine whether the successive stimulus events represented features drawn from the same basic item. Cue type influenced reaction times to pictures and environmental sounds, but the effects were qualified by response type and with picture targets by presentation side. These results provide some additional evidence of processing asymmetry when pictures are directed to either the right or left hemisphere, as well as for some asymmetries in cross-modality cuing. Implications of these findings for theories of multisensory processing and models of object recognition are discussed.
