Comportamiento de los edificios de HA con tabiquería durante el sismo de Lorca de 2011: aplicación del método FAST
Authors: Gómez-Martínez F. , Pérez-García A. , De Luca F. , Verderame M.
Published: April 2015

Se ofrece una hipótesis de comportamiento de los edificios porticados de hormigón armado de Lorca ante el terremoto de 2011, mediante la aplicación del método FAST, procedimiento de estimación simplificada de la vulnerabilidad a gran escala de dichos edificios contando con la contribución estructural de la tabiquería de fábrica. Este terremoto tuvo una aceleración de pico (PGA) tres veces superior a la básica de proyecto; sin embargo, se caracterizó por la práctica ausencia de colapsos. Se estudian las propiedades del evento sísmico y las particularidades de la edificación para, a través de la aplicación de FAST, tratar de confirmar que dicha ausencia de colapsos pudiera deberse a la contribución estructural de la tabiquería, a pesar de no ser proyectada con ese fin ni regulada por las sucesivas regulaciones normativas. Los resultados obtenidos confirman en buena medida dicha hipótesis, siendo el nivel medio de daño previsto consistente con el escenario real.

A Simplified Method for Understanding Judgment and Decision Making of Muslim Consumers
Authors: Burhanudin
Published: April 2015

The large number of Muslims in the world provides many attractive market segments. This then raises the question on how marketers can best understand the judgment and decision making of Muslims toward designing appropriate campaigns that could effectively target their communities. This chapter reviews general human judgment and decision making and proposes a simplified method for understanding this market through identifying the one reason that drives consumer decision making. One-reason decision making is common among consumers. It consumes little information to reach a conclusion, but has similar accuracy with other methods that consume more than twice the amount of information. For marketers, this simplified method would help them penetrate those markets about which they have little understanding. And for marketers who do understand a market, this method can help them in designing their campaigns more efficiently. Simple intervention strategies to attract Muslim consumers are discussed at the end of this chapter.
Consumer Behavior in Islam
Authors: Alkhasawneh Abdul Hadi M.
Published: April 2015

Consumer behavior in Islam has emerged as a promising area of interest to researchers in Islamic economics in recent years. This chapter aims to develop an understanding of consumer behavior in Islam, reflecting on the teachings and values of Islam. It also goes on to identify the nature and characteristics of the utility function in the context of Islamic economics. Islam has given great attention to the consumer as a member of the community. Many of the verses of Holy Quran and sayings of the Prophet Mohammad (PBUH) indicate the need for consumer protection in accordance with the provisions of the Islamic Shariah. Consumer protection in Islamic economics can be achieved by a set of Islamic guidelines established in the Holy Quran and Sunnah that indicate the need for Muslim consumers to control the source of spending through the consumption of lawful and beneficial goods and services.

Authors: Chamhuri Norshamliza , Kusumawaty Yeni , Batt Peter J.
Published: April 2015

This chapter seeks to compare and contrast the purchase of fresh meat between modern retail stores and traditional markets in both Malaysia and Indonesia. In-depth focus group discussions with the main food shoppers in the household reveal that the halal status is the most influential criterion in store choice for fresh chicken meat. Other important criteria include freshness, quality, a competitive price, convenience, an on-going relationship with the retailer, the variety available, and a pleasant shopping environment.
Islamic Marketing
Authors: Sarofim Samer , Tolba Ahmed
Published: April 2015

The ultimate objective of this chapter is to provide a new conceptualization that encompasses Islam as a religion, Islamic culture, and Islamic politics to provide both academicians and practitioners with a multidimensional understanding of interrelated factors in Islamic marketing. It illustrates how cultural factors and political associations intersect with Islamic teachings and rules to shape the Muslim consumer behaviors and decision-making process; consequently, business and marketing strategies aimed at targeting Muslim consumers are either threatened or reinforced.
Luxury Consumption Behavior of Muslim Customers in a Culturally Distinct and an Affluent Market
Authors: Sharif Khurram , Kassim Norizan M
Published: April 2015

This chapter explores the luxury consumption behavior of affluent Muslim consumers within a rich Islamic country. Hofstede (1983) cultural dimensions were used to make comparisons between materialistic and relational approaches impacting Quality of Life. Islamic ideologies of Comprehensiveness, Moderation, and Necessities were utilized in evaluation of consumption behavior of rich Muslims. In addition, impact of gender, education, and income on luxury consumption behavior were analyzed to afford a view associated with thinking and actions of affluent Muslim consumers. Hence, the fundamental objective of the chapter was to present, largely through relevant literature support and observations, the Islamic and social perspectives of consumption, Quality of Life orientations and their association with consumption, key demographics likely to play an important part in shaping and practice of luxury consumption amongst affluent Muslim consumers.
Demystifying the Islamic Consumer Segments
Authors: Rishi Bikramjit , Halder Subhankar
Published: April 2015

The rise of the Islamic Marketing has attracted the attention of the marketers to bring Islamic perspectives in their marketing actions. There are four major pillars (i.e. Spiritualistic, Ethical, Realistic, and Humanistic), which must be focused while transacting with the Muslim consumers. This chapter synthesizes the literature available in Islamic marketing by contextualizing the need of segmenting the Muslim consumers. The chapter lists the need to segment the Muslim consumers and tries to establish a linkage with the ethical practices in Islam to create a basis for segmentation. The chapter concludes that it would be a massive overgeneralization if Muslims were assumed to be one uniform group. In fact, as noted in the essay, several differences exist within this multicultural community. It is of importance that companies acknowledge these differences, understand the possibility of numerous segments within the Muslim community.
Accepting a New Nano-Tech-Based Technology in the Fruit Storage Industry
Authors: Omrani Azad , Vallaster Christine
Published: April 2015

Nanotechnology is increasingly being employed in the areas of food production and packaging. While there exists considerable research that analyses consumer trust and perception of nanotechnology use in the food sector, the B2B sector has widely been neglected. This research project analyzes the influence of perceived quality and psychological factors in adopting a new nano-based technology that increases storage life of fruits and vegetables. The research context is Iran and neighboring countries. The results show that customer acceptance of using nanotechnology is influenced by both quality dimensions (performance, features, reliability, conformance, durability, serviceability, aesthetics, perceived quality) and psychological dimensions such as perceived risk and trust. The research also reveals individual differences in accepting nano-technology, depending on the function held by the employee. The authors interpret the results from a culture perspective.
Service Convenience
Authors: Stephens Paul , McGowan Matthew
Published: April 2015

In this research, the authors assess the applicability of the SERVCON model to the e-commerce (e-service) environment in the context of student textbook purchases. Following a literature review, a survey was developed based on previous scales; items were modified to fit the e-commerce environment. The survey was administered to college students in business courses, and 281 usable responses were received. Factor analysis resulted in several items being dropped, but the six factor SERVCON model was validated in the online environment. The validated model was used to compare service convenience perceptions between students purchasing books online and students purchasing books by traditional methods (brick-and-mortar). The service convenience measures for online purchases than brick-and-mortar purchases for decision, access, benefit, transaction, and postbenefit convenience. The study validates the SERVCON model in the e-service environment, and extends work that explains consumer behavior in e-services. Traditional bookstores need to explore options to improve services in the brick-and-mortar environment. Online vendors can improve their web sites to provide better service convenience to their customers.
The Interactions between Information and Communication Technologies and Innovation in Services
Authors: Nardelli Giulia
Published: April 2015

Recent literature reveals the increasingly important role of Information and Communication Technologies (ICT) within innovation in services. This paper aims at outlining how scholars have conceptualized and defined the relationship between ICT and innovation in services so far, by analysing the fragmented body of knowledge available on the topic, to strengthen the research area as field of study and support its progress. The results of the literature review were derived through a concept-centric analysis of the existing research on ICT and innovation in services. The outcome of the literature review is a conceptual typology that organizes and summarizes the body of knowledge on ICT and innovation in services, and reveals the critical knowledge gaps along with an agenda for future research. The main contribution of this work resides in having organized existing literature on the relationship between ICT and innovation in services into a conceptual typology. The conceptual typology outlines the three main aspects of the link between ICT and innovation in services: the integration of organizational and innovation processes; the cooperation among internal and external agents; and the self-reinforcing innovation mechanism that characterizes ICT as a product.
A Source Code Plagiarism Detecting Method Using Sequence Alignment with Abstract Syntax Tree Elements
Authors: Kikuchi Hiroshi , Goto Takaaki , Wakatsuki Mitsuo , Nishino Tetsuro
Published: April 2015

Learning to program is an important subject in computer science courses. During programming exercises, plagiarism by copying and pasting can lead to problems for fair evaluation. Some methods of plagiarism detection are currently available, such as sim. However, because sim is easily influenced by changing the identifier or program statement order, it fails to do enough to support plagiarism detection. In this paper, the authors propose a plagiarism detection method which is not influenced by changing the identifier or program statement order. The authors also explain our method's capabilities by comparing it to the sim plagiarism detector. Furthermore, the authors reveal how our method successfully detects the presence of plagiarism.
Service-Oriented Software Engineering
Authors: Baghdadi Youcef
Published: April 2015

Method engineering techniques albeit proven effective for paradigms such as function, object and component, are pertinent to limited aspects of service orientation (SO). The comparison frameworks show that the produced methods neither conform to SO design principles nor to SOA, which is an issue. This paper proposes a framework to guide engineering methods for service-oriented software engineering. It describes a method by its aggregates and the relationships between elements such as Service Science (SS), SO, SOA, SOC, and Web. The paper also describes the guidance for method engineering. The framework consists of two layered categories of entities: (C1) conceptual foundation entities: SS, SO, and SOA, and (C2) realization infrastructure entities: SOC and Web. These entities request and provide services from/to each other. The framework comprehensively describes the SOSE environment, enforces the construct service with fundamental properties and principles, produces SOSE methods that address the challenges of software engineering, and benchmarks the existing SOSE methods.
Functional Testing Using OCL Predicates to Improve Software Quality
Authors: Jalila A. , Mala D. Jeya , Eswaran M.
Published: April 2015

Formal specification-based testing is one of the major criterions to detect faults in the requirement specification or design of a system. However, due to the non-availability of implementation details, test case generation from formal specifications become a challenging task. This research work has proposed an automated fault-based testing framework to test the specification of a system written in OCL (Object Constraint Language). Accordingly, the possible faults in OCL specification of a system have been anticipated by mutating its method based on predicate-based fault classes. Then, test cases are generated by applying Chaotic Simulated Annealing (CSA) algorithm. In this paper, a novel OCL predicate based fitness function is defined to evaluate the generated test data. The experiment results indicate that the OCL specification based testing adopting CSA form an excellent combination for performing functional testing at the earliest to improve software quality.
Four categories of patient participation in treatment and their linkage to decision-making in a structure of 81 models
Authors: Heggland Liv-Helen , Hausken Kjell
Published: April 2015

We clarify patient participation by developing a systematic structure of 34=81 models spanned out by three subcategories for each of four categories. Choosing a qualitative descriptive research design, and applying purposive sampling, four doctors, seven nurses, and seven patients were selected to ensure a broad representative sample with experts of varying ages and sexes from medicine and nursing. The preferences of these were mapped onto the theoretical structure. Applying content analysis, meaning units were identified, condensed and coded. The four categories information dissemination, formulation of options, integration of information and control were shown to be exhaustive, and mutually exclusive through time causing a topdown process where one occurs before the other through four stages. The three subcategories specify how patients, healthcare professionals, or both, operate within each category. That is, either patients are active in some sense that is specified, or healthcare professionals are active in some sense, or both are active. Delineating a structure of 34=81 models, based on four categories and three subcategories, gives a richer structure than what has earlier been available. This almost all-embracing structure enables pinpointing the exact nature of any culture involved in care of patients, which illuminates how the culture reflects or can potentially be altered to reflect values of patient care that we respect.
A protocol for literature triage in online learning for the net-generation nursing and allied health care students
Authors: Ateya Maryam , Khalil Ebrahim , Rasheed Sara , Asokan Govindaraj Vaithinathan
Published: April 2015

Nursing and allied health care students use online learning resources with their own perspective of learning, often combined with curiosity. Although, students are overwhelmed with access to an enormous pool of information, we hypothesized that students may not possess the skills to appraise the merits of all online resources. Our pilot survey results have shown that students’ knowledge of literature appraisal is inadequate. Circumventing this barrier requires adopting a three-phase protocol for literature triage such as: selection, appraisal, and critical reading. These skills would facilitate assessing all aspects of the literature, and identifying the best learning material.

Authors: Adedeji Asafa R. , Tumbo John , Govender Indiran
Published: April 2015

Background: Clinical guidelines are systematically developed statements that assist practitioners and patients to make healthcare decisions for specific clinical circumstances. Non-adherence of doctors to guidelines is thought to contribute significantly to poor delivery of clinical care, resulting in poor clinical outcomes.Aim: To investigate adherence of doctors in rural district hospitals to clinical guidelines using the South African Hypertension Guideline 2006 as an example.Setting: Four district hospitals in Bojanala district of North-West Province, South Africa.Methods:A cross-sectional study determined adherence practices of doctors from records of patients with established hypertension seen at the four district hospitals.Results: Of the 490 total records documented by 29 doctors, screening for co-morbidity or associated factors was carried out as follows: diabetes mellitus 99.2%, obesity 6.1%, smoking 53.5%, dyslipidaemia 36.9%, abdominal circumference 3.3%; organ damage: eye 0, kidney 82%, heart 43.5%, chronic kidney disease 38.2%, stroke/transient ischaemic attack 15.9%, heart failure 23.5%, advanced retinopathy 0.2%, coronary heart disease 23.7%, peripheral arterial disease 13.9%. Critical tests/measurements were documented in the following proportions: blood pressure 99.8%, weight 85.3%, height 65.7%, body mass index 3.1%, urinalysis 74.5%, lipogram 76.1%, urea/creatinine 80.4%, electrocardiogram 42.9%, blood glucose 100%; risk determination and grading: diagnosis by hypertension severity 19%, low added risk 57.1%, moderate added risk 64.7%, high added risk 89.6%, very high added risk 89.2%. Adherence to therapies was as follows: first-line guideline drugs 69.4%, second line 84.7%, third line 87.8% and fourth-line 89.6%.Conclusion: Overall adherence of doctors to treatment guidelines for hypertension was found to be low (51.9%). Low adherence rates were related to age (older doctors) and less clinical experience, and differed with regard to various aspects of the guidelines.

Published: April 2015

Objective: Surgical management of giant skull osteomas Osteomas are benign, generally slow growing, bone forming tumors limited to the craniofacial and jaw bones. Materials and Methods: A retrospective review of all cases of osteoma diagnosed from 2009 to 2013 treated in our hospital. The data collected included age at diagnosis, gender, lesion location, size, presenting and duration of symptoms, treatment, complication and outcome.
Results: During our study period there were 15 cases that were treated surgically. Their mean age was 42 years (range: 15–65 years) and all of our patients were female. The average duration of symptoms was 3 years and size varying from 4 cm to 12 cm. Eight patients complained of headache, whereas 6 patients complained about esthetics, and 1 patient presented with proptosis. The tumor was excised by cutting the base of the tumor and then residual tumor was grinded using a round head cutting bar. Osteoma was removed with esthetically acceptable appearance.
Conclusion: There were no major complications during operative and postoperative period. Although osteomas are usually slow growing but surgery is usually performed due to esthetic reasons. It is important to plan an appropriate surgical approach that minimizes any damage to the adjacent structures.

Authors: Kim Hyeun , Ju Chang , Kim Seok , Kim Jong , Lee Seung , Kim Byoung
Published: April 2015

Background: Acute lumbar disc herniation can occur in every lumbar intervertebral disc space and in multiple levels simultaneously. In the cases of 2 levels adjacent lumbar disc herniations of severe unilateral radiculopathic leg pain caused by compression of the nerve roots, respectively, multiple incision or long incision is generally needed for simultaneous removal of disc fragment in 2 levels. Objectives: We proposed the minimally invasive one portal skin incision endoscopic discectomy is effective and safe method to treat 2 levels adjacent lumbar disc herniation. Materials and Methods: We have experimented total 8 cases of 2 levels adjacent lumbar disc herniation having unilateral radiculopathic pain respectively. All cases are 2 levels adjacent lumbar disc herniation. We have tried a percutaneous endoscopic transforaminal approach through minimal one portal skin incision and remove the two herniated disc materials in the adjacent levels. Results: The L2-L3 level was involved in 2 patients, L3-L4 level in 6 patients, while the L4-L5 level was involved in 7 patients, L5-S1 level in 1 patient. The mean follow-up was 18.5 months. The mean visual analogue score (VAS) of the patients prior to surgery was 7.75, and the mean postoperative VAS was 2.375. According to Macnab's criteria, 3 patients had excellent results, 4 patients had good results, 1 patient had fair results, and no patient had a poor result; satisfactory results were obtained in 87.5% of the cases. Conclusion: The percutaneous endoscopic transforaminal approach through 1 skin portal incision could be effective surgical method in unilateral adjacent 2 levels lumbar disc herniation.
Impact of electrolyte imbalances on the outcome of aneurysmal subarachnoid hemorrhage: A prospective study
Authors: Alimohamadi Maysam , Saghafinia Masoud , Alikhani Fariba , Danial Zohreh , Shirani Mohamad , Amirjamshidi Abbas
Published: April 2015

Background: Electrolyte disturbances are frequently observed during the acute and subacute period after subarachnoid hemorrhage (SAH) and may potentially worsen therapeutic outcome. This study was conducted to determine the pattern of electrolyte disturbance in the acute and subacute phase after SAH and their effect on the long-term outcome of the patients. Materials and Methods: Fifty-three patients were prospectively enrolled. The standards of care for all patients were uniformly performed. The serum levels of electrolytes (sodium, potassium and magnesium) were determined with measurements obtained on admission, 3–5 and 7–10 days after SAH. Radiographic intensity of hemorrhage (Fisher's scale), and the clinical grading (World Federation of Neurosurgical Societies grade) were documented in the first visit. The outcomes were evaluated using Glasgow outcome scale at 3 months after discharge. Results: Hyponatremia was the most common electrolyte imbalance among the patients but did not worsen the outcome. Although less common, hypernatremia in the subacute phase was significantly associated with poor outcome. Both hypokalemia and hypomagnesemia were predictive of poor outcomes. Conclusions: Because electrolyte abnormalities can adversely affect the outcome, the serum levels of electrolytes should be closely monitored with serial measurements and treated properly in patients with aneurysmal SAH.

Incidental diagnosis of two intracranial aneurysms following surgical evacuation of chronic subdural hematoma
Authors: Das Joe , Rajmohan B , Sharmad M , Peethambaran Anilkumar
Published: April 2015

The development of subarachnoid hemorrhage (SAH) following evacuation of chronic subdural hematoma (CSDH) is a very rare phenomenon. SAH in this context occurring secondary to intracranial aneurysm rupture is still rare. We report a case of an elderly lady who presented with right hemiplegia and altered sensorium. Computed tomography (CT) scan of the brain revealed a left fronto-temporoparietal CSDH with midline shift, which was promptly evacuated surgically via a single burr-hole. Postoperatively, her level of consciousness deteriorated and there was increased the amount of drain. Emergency CT of the brain revealed diffuse SAH. CT cerebral angiogram revealed one aneurysm each in the right internal carotid artery and anterior communicating artery. Meanwhile, her consciousness level improved on conservative management. The relatives were not keen for further follow-up.
Occam's razor in the management of ventriculoperitoneal shunt dysfunction: Diagnosis and management of an unusual pediatric case
Authors: Dadlani Ravi , Dadlani Reena , Ghosal Nandita , Hegde Alangar
Published: April 2015

Ventriculoperitoneal (VP) shunt surgery is probably the commonest surgical procedure in neurosurgery. Belying its technical simplicity is the myriad complications associated with it. Shunt malfunction is a common complication associated with this surgery, second only to shunt related infections, which may be associated with it. Sterile cerebrospinal fluid (CSF) eosinophilia (CE) has been reported with VP shunts, which may or may not be related to the dysfunction. Eosinophilia in the CSF has also been associated with a number of other conditions including parasitic infestations in the brain. This may be unrelated to the shunt surgery. We present a case of a child, operated earlier for hydrocephalus, who presented with sub-acute loss of vision and bilateral oculomotor paresis. CSF from a chamber tap revealed eosinophilia. The commonest presenting symptom of shunt malfunction is raised intracranial pressure. There are no reports in the literature of VP shunt malfunction presenting with bilateral oculomotor paresis and decreased visual acuity. The associated CE complicated the clinical picture, especially since the initial brain radiology was normal. We discuss the clinical differential diagnosis of this very interesting presentation, management dilemmas and outcome in this child. This rare clinical presentation was found to be the result of a shunt malfunction and not due to any rare parasitic infestation of the brain. Occam's razor dictates that the simplest explanation in a given situation is usually the most accurate, as is seen in this case.

A transformation rule for the index of commuting operators
Authors: Kaad Jens , Nest Ryszard
Published: April 2015

In the setting of several commuting operators on a Hilbert space one defines the notions of invertibility and Fredholmness in terms of the associated Koszul complex. The index problem then consists of computing the Euler characteristic of such a special type of Fredholm complex.

In this paper we investigate transformation rules for the index under the holomorphic functional calculus. We distinguish between two different types of index results:

Our results apply to the example of Toeplitz operators acting on both Bergman spaces over pseudoconvex domains and the Hardy space over the polydisc.

The local index theorem is fundamental for future investigations of determinants and torsion of Koszul complexes.
The Dolbeault dga of the formal neighborhood of the diagonal
Authors: Yu Shilin
Published: April 2015

A well-known theorem of Kapranov states that the Atiyah class of the tangent bundle

TX

of a complex manifold

X

makes the shifted tangent bundle

TX[-1]

into a Lie algebra object in the derived category

D(X)

. Moreover, he showed that there is an

L_\infty

-algebra structure on the shifted Dolbeault resolution

(\mathcal A^{\bullet-1}_X(TX),\overline{\partial})

of

TX

and wrote down the structure maps explicitly in the case when

X

is Kähler. The corresponding Chevalley-Eilenberg complex is isomorphic to the Dolbeault resolution

(\mathcal A^{0,\bullet}_X(\mathcal{J}^\infty_X),\overline{\partial})

of the jet bundle

\mathcal{J}^\infty_X

via the construction of the holomorphic exponential map of the Kähler manifold. In this paper, we show that

(\mathcal A^{0,\bullet}_X(\mathcal{J}^\infty_X),\overline{\partial})

is naturally isomorphic to the Dolbeault dga

(\mathcal A^\bullet(X_{X \times X}\scriptscriptstyle {(\infty)},\overline{\partial})

associated to the formal neighborhood of the diagonal of

X \times X

which we introduced in [15]. We also give an alternative proof of Kapranov's theorem by obtaining an explicit formula for the pullback of functions via the holomorphic exponential map, which allows us to study the general case of an arbitrary embedding later.
Holomorphically finitely generated algebras
Authors: Pirkovskii Alexei Yu.
Published: April 2015

We introduce and study
holomorphically finitely generated
(HFG) Fréchet algebras, which are analytic counterparts of affine (i.e., finitely generated)

\mathbb C

-algebras. Using a theorem of O. Forster, we prove that the category of commutative HFG algebras is anti-equivalent to the category of Stein spaces of finite embedding dimension. We also show that the class of HFG algebras is stable under some natural constructions. This enables us to give a series of concrete examples of HFG algebras, including Arens–Michael envelopes of affine algebras (such as the algebras of holomorphic functions on the quantum affine space and on the quantum torus), the algebras of holomorphic functions on the free polydisk, on the quantum polydisk, and on the quantum polyannulus.

О нерелятивистском двумерном чисто магнитном суперсимметричном операторе Паули
Authors: Grinevich Petr Georgievich , Mironov Andrei Evgen'evich , Novikov Sergei Petrovich
Published: April 2015

В статье полное многообразие собственных функций основного состояния для чисто магнитного 2D-оператора Паули рассматривается как побочный продукт новой редукции, найденной авторами несколько лет назад для алгебро-геометрических обратных спектральных данных (т.е. римановых поверхностей и дивизоров). Эта редукция ассоциирована с $(2+1)$-солитонной иерархией, содержащей 2D-аналог известной "системы Бюргерса". Эта статья содержит также изложение предыдущих работ, выполненных с 1980 г., включая первые топологические идеи в пространстве квазиимпульсов. Мы также даем новые результаты, посвященные самосопряженным граничным задачам для оператора Паули. Нулевой 2D-уровень "неспектральных" функций Блоха-Флоке дает дискретные точки дополнительного спектра аналогично "граничным состояниям" конечнозонных 1D-потенциалов в зонах.

Coleadership Among Chief Residents: Exploration of Experiences Across Specialties
Authors: Pettit Jeffrey E.
Published: April 2015

Background

Many departments have multiple chief residents. How these coleaders relate to each other could affect their performance, the residency program, and the department.

Objective

This article reports on how co-chiefs work together during the chief year, and what may allow them to be more effective coleaders.

Methods

A phenomenological research design was used to investigate experiences of outgoing chief residents from 13 specialties at the University of Iowa Hospitals and Clinics over a 2-year period from 2012 through 2013. Thematic analysis of semistructured interviews was conducted to investigate commonalities and recommendations.

Results

Face-to-face interviews with 19 chief residents from 13 different specialties identified experiences that helped co-chiefs work effectively with each other in orienting new co-chiefs, setting goals and expectations, making decisions, managing interpersonal conflict, leadership styles, communicating, working with program directors, and providing evaluations and feedback. Although the interviewed chief residents received guidance on how to be an effective chief resident, none had been given advice on how to effectively work with a co-chief, and 26% (5 of 19) of the respondents reported having an ineffective working relationship with their co-chief.

Conclusions

Chief residents often colead in carrying out their multiple functions. To successfully function in a multichief environment, chief residents may benefit from a formal co-orientation in which they discuss goals and expectations, agree on a decision-making process, understand each other's leadership style, and receive feedback on their efficacy as leaders.

Eighty-three patients aged between 7 and 55 years old presenting 180 traumatized teeth that suffered extrusive luxation (n = 67), lateral luxation (n = 69), intrusive luxation (n = 10) and tooth avulsion (n = 34) followed by replantation were evaluated. The follow-up period was 24 months. The complications examined were: pulp canal obliteration, pulp necrosis and root resorption (inflammatory and replacement). Furthermore, the relationship between time elapsed before receiving dental attendance and development of inflammatory resorption was observed.

Results

Pulp necrosis was the main complication, occurring in 147 teeth (82.7%). All of the teeth that suffered intrusive luxation and tooth avulsion were diagnosed with pulp necrosis, with significant difference in comparison with another traumas (p < 0.001/Fisher's exact test). Inflammatory root resorption was observed in 20.5% of the cases and replacement resorption was more related to tooth replantation (94.1%), showing significant prevalence among tooth luxations (p < 0.001/Fisher's exact test). In addition, it was noted that patients who seek treatment 9 weeks after the trauma episode presented 10 times more chance of developing inflammatory resorption when compared with patients who seek treatment soon after dental trauma (Odds ratio test).

Conclusion

It may be concluded that pulp necrosis was the main post-traumatic complication observed in traumatized teeth and that delay in seeking treatment may damage the prognosis of severe luxation and replanted teeth.

Clinical significance

Clinical studies describing the main complications that may affect traumatized teeth present great relevance to make the population aware of the importance of seeking immediate treatment and to alert the professional to the need for follow-up. When traumatic injuries are diagnosed and treated early, post-traumatic complications may be controlled, allowing conservation of the tooth in oral cavity.

Comparing Three Different Three-dimensional Scaffolds for Bone Tissue Engineering: An in vivo Study
Authors: Nosouhian Saeid , Davoudi Amin , Rismanchian Mansour , Razavi Sayed Mohammad , Sadeghiyan Hamidreza
Published: April 2015

Introduction

Three-dimensional Scaffold structure of synthetic biomaterials with their interconnected spaces seem to be a safe and effective option in supporting bone regeneration. The aim of this animal study was to compare the effectiveness of three different biocompatible scaffolds: bioglass (BG), demineralized bone matrix (DBM) and forstrite (FR).

Materials and methods

Four healthy dogs were anesthetized and the first to fourth premolars were extracted atraumatically in each quadrant. After healing, linear incision was prepared from molar to anterior segment and 4 defects in each quadrant (16 defects in each dog) were prepared. Scaffold blocks of BG, DBM and FR were resized according to size of defects and placed in the 12 defects randomly, 4 defects remained as control group. The dogs were sacrificed in 4 time intervals (15, 30, 45 and 60 days after) and the percentage of different types of regenerated bones (lamellar and woven) and connective tissue were recorded in histological process. The data were analyzed by one-way ANOVA and post hoc using SPSS software Ver. 15 at significant level of 0.05.

Results

In day 30th, although the amount of regenerated lamellar bone in control, DBM and BG Scaffold (22.37 ± 3.44; 21.46 ± 1.96; 21.21 ± 0.96) were near to each, the FR Scaffold provided the highest amount of lamellar (29.71 ± 7.94) and woven bone (18.28 ± 2.35). Also, FR Scaffold showed significant difference with BG (p = 0.026) and DBM Scaffolds (p = 0.032) in regenerated lamellar bone.

Conclusion

We recommend paying more attention to FR Scaffold as a biomaterial, but it is better to be compared with other nano biomaterials in future studies.

Intramucosal Nevus in the Oral Cavity
Authors: Freitas Daniel Antunes , Bonan Paulo Rogério , Sousa Arlen Almeida , Pereira Mayane Moura , Oliveira Stephany Mendes , Jones Kimberly Marie
Published: April 2015

Aim

The aim of this study is to report a clinical case of oral nevus.

Background

Nevus is a congenital or acquired benign neoplasia that can be observed in the skin or mucous membranes. It is an uncommon condition in the oral mucosa. When it does occur, the preferred location is on the palate, followed by the cheek mucosa, lip and tongue.

Case report

In this case study, we relate the diagnosis and treatment of a 23-year-old female patient with an irregular, pigmented lesion of the oral mucosa that underwent excisional biopsy resulting in a diagnosis of intramucosal nevus.

Conclusion

Nevus can appear in the oral mucosa and should be removed.

Clinical significance

It is important for dental professionals to adequately categorize and treat pigmented lesions in the mouth.

Instrumental Activities of Daily Living Performance and Role Satisfaction in People With and Without Mild Cognitive Impairment: A Pilot Project
Authors: Ciro Carrie A. , Anderson Michael P. , Hershey Linda A. , Prodan Calin I. , Holm Margo B.
Published: April 2015

OBJECTIVE. We investigated differences in observed performance of instrumental activities of daily living (IADLs) and self-reported satisfaction with social role performance between people with amnestic mild cognitive impairment (a-MCI) and age- and gender-matched control participants.

METHOD. We measured observed performance of 14 IADLs using the Independence, Safety, and Adequacy domains of the Performance Assessment of Self-Care Skills (PASS) and the Patient-Reported Outcomes Measurement Information Systems (PROMIS) to examine satisfaction with social role performance.

RESULTS. Total PASS scores were significantly lower in participants with a-MCI (median = 40.6) than in control participants (median = 44.2; p = .006). Adequacy scores were also significantly lower. No significant differences were found between groups on the PROMIS measures.

CONCLUSION. IADL differences between groups were related more to errors in adequacy than to safety and independence. Occupational therapy practitioners can play a key role in the diagnosis and treatment of subtle IADL deficits in people with MCI.
Handwriting Proficiency Screening Questionnaire for Children (HPSQ–C): Development, Reliability, and Validity
Authors: Rosenblum Sara , Gafni-Lachter Liat
Published: April 2015

OBJECTIVE. To adapt the Handwriting Proficiency Screening Questionnaire (HPSQ), previously designated for adults, into a children’s self-report version (the HPSQ for Children, or HPSQ–C) and to examine its reliability and validity.

METHOD. Participants included 230 children ages 7–14 yr from regular schools in Israel. The questionnaire’s content validity, internal consistency, and concurrent and construct validity were assessed.

RESULTS. The tool demonstrated good internal consistency (α = .77). We found a significant moderate correlation between final HPSQ–C scores and the HPSQ, r = .51, p < .001, establishing the HPSQ–C’s concurrent validity. Construct validity was also confirmed. Results demonstrated that the HPSQ–C significantly distinguished between children with and without handwriting deficiencies on the basis of measures of handwriting product (Hebrew Handwriting Evaluation) and handwriting process (Computerized Penmanship Evaluation Tool).

CONCLUSION. The HPSQ–C is suitable for identification of handwriting deficiency among school-aged children and is appropriate for varied academic and clinical uses.

Authors: Rosenberg Lori , Maeir Adina , Yochman Aviva , Dahan Idit , Hirsch Idit
Published: April 2015

OBJECTIVE. To test functional improvement after a group cognitive–functional occupational therapy intervention for preschoolers with attention deficit hyperactivity disorder (ADHD).

METHOD. Seventeen preschooler–parent dyads attended 11 weekly group sessions focused on acquiring executive strategies through occupational performance. Functional improvement was measured using the Canadian Occupational Performance Measure (COPM) and Goal Attainment Scaling (GAS); executive function, using the Behavior Rating Inventory of Executive Function–Pediatric; ADHD symptomatology, using Conners’ Parent Rating Scale–Revised and Conners’ Teacher Rating Scale–Revised; and social functioning, using the Social Participation scale of the Sensory Processing Measure.

RESULTS. Significant improvement was found on the COPM and GAS measures, whereas mixed results were found on the other measures, with improvements found in children whose scores indicated impairment at baseline.

CONCLUSIONS. Cognitive–functional group intervention appears to significantly improve daily functioning, executive function, and social functioning for children who demonstrate clinical impairment. Further research with a larger sample, a control group, and follow-up is required.
Observational Characterization of Sensory Interests, Repetitions, and Seeking Behaviors
Authors: Kirby Anne V. , Little Lauren M. , Schultz Beth , Baranek Grace T.
Published: April 2015

Sensory interests, repetitions, and seeking behaviors (SIRS) are common among children with autism spectrum disorder (ASD) and other developmental disabilities (DD) and involve unusual actions that intensify or reinforce a sensory experience. Researchers and practitioners typically use parent-report measures or informal clinical observations to understand the presence and nature of SIRS. In this study, we used a scoring supplement to the Sensory Processing Assessment for Young Children, an observational measure, to characterize SIRS across three groups of children—those with ASD (n = 40), DD (n = 37), and typical development (n = 39). Group differences were identified in frequency and intensity of overall SIRS, complexity of SIRS, and incidence of particular types of SIRS (i.e., posturing, sighting, proprioceptive seeking, spinning). Facial affect was also explored and found to be primarily neutral during engagement in SIRS across groups. Implications for practice and future research are discussed.
