Before making investment decisions, investors need to analyze the pattern of trading days which change daily because of investors’ behavior in stock trading activity that affects the pattern of daily stock price movements. Changes in macro variables like exchange rates for instance, also can affect share price. To determine the influence of independent variables (day of the week effect and exchange rate) on the dependent variable (Jakarta Composite Index (JCI)), a research is conducted using multiple linear regression analysis. The initial test uses a test of normality and is resumed by testing multiple linear regression analysis and classical assumption. The hypothesis test uses t-statistics and F-statistics with a significance level of 5%. A descriptive statistics implies that there is an effect of trading days on stock prices. However, using backward stepwise linier regression model and multivariate analysis, the result indicates that there is no effect of trading days on stock prices. Using multivariate data analysis, it is found that stock prices is influenced by exchange rate.

Authors: Astini Rina
Published: August 2017

Article presents a measurement of the effects of satisfaction and trust in connection with customer loyalty, and a direct and indirect effects of switching cost on customer loyalty. Data were collected from 42 respondents coming from GSM customers. Data was analyzed by using path analysis methods. The study found that satisfaction did not necessarily affect customers’ loyalty. Relationship of customer satisfaction and trust was greatly influenced by perception of customers towards the cost of switching. Level of satisfaction and respondent loyalty average was 69.7% and the average value of customer loyalty was 78.73%.  The research result indicates that  trust and switching cost jointly influence customer loyalty. Trust is more important than customer satisfaction in influencing customer loyalty, where the trust contains belief towards a brand, which will produce a positive outcome both in the present and in the future. Customer satisfaction does not contain this dimension. It is concluded that GSM operators shall have to focus on trust rather than satisfaction.
Effects of sea level rise on hydrology: case study in a typical mid-Atlantic coastal watershed
Authors: Wang Xixi , Li Rui , Taghadomi Homa Jalaeian , Pedram Shohreh , Zhao Xiao
Published: August 2017

Sea level rise (SLR) can negatively affect the hydrology of coastal watersheds. However, the relevant information is incomplete and insufficient in existing literature. The objective of this study is to present a modeling approach to predict long-term effects of SLR on changes of flood peak, flood stage, and groundwater table with an assumption that the historical climate would reoccur in the future. The study was conducted for a typical coastal watershed in southeast USA. The results indicate that sea level had been rising at a rate of 4.21 mm yr−1 from 1948 to 1982 but at a faster rate of 5.16 mm yr−1 from 1983 to 2013. At such SLR rates and by 2113, the groundwater table beneath the eastern part of the watershed would be raised by 0.10 to 0.29 m, while the annual mean peak discharge and flood stage at the watershed outlet would be increased by 13.84 m3 s−1 (from 3.63 to 17.47 m3 s−1) and 0.92 m (from zero to 0.92 m), respectively. The other parts of the watershed would be relatively less affected by SLR. For coastal watersheds, SLR will probably raise the groundwater table, and increase the magnitude and occurrence of peak discharge and flood stage.
On the Mints Hierarchy in First-Order Intuitionistic Logic
Authors: Schubert Aleksy , Urzyczyn Paweł , Zdanowski Konrad
Published: August 2017

We stratify intuitionistic first-order logic over $(\forall,\to)$ into
fragments determined by the alternation of positive and negative occurrences of
quantifiers (Mints hierarchy).
We study the decidability and complexity of these fragments. We prove that
even the $\Delta_2$ level is undecidable and that $\Sigma_1$ is
Expspace-complete. We also prove that the arity-bounded fragment of $\Sigma_1$
is complete for co-Nexptime.
Compositional bisimulation metric reasoning with Probabilistic Process Calculi
Authors: Gebler Daniel , Larsen Kim G. , Tini Simone
Published: August 2017

We study which standard operators of probabilistic process calculi allow for
compositional reasoning with respect to bisimulation metric semantics. We argue
that uniform continuity (generalizing the earlier proposed property of
non-expansiveness) captures the essential nature of compositional reasoning and
allows now also to reason compositionally about recursive processes. We
characterize the distance between probabilistic processes composed by standard
process algebra operators. Combining these results, we demonstrate how
compositional reasoning about systems specified by continuous process algebra
operators allows for metric assume-guarantee like performance validation.

Results:

The ATFL injuries could be divided into six subtypes based on ultrasound imaging: I: Intact ligament; II: Injury at the fibular side; III:Injury at the talar side; IV: Tear at the midsubstance; V:Ligament absorbed; VI:Combined injury.

Conclusion:

Ultrasound could be used to evaluate and type the injury of ATFL. This kind of classification could be helpful in the preoperative decision of ATFL procedure.
Role of Surgery in Management of Osteo-Articular Tuberculosis of the Foot and Ankle
Authors: Dhillon Mandeep Singh , Agashe Vikas , Patil Sampat Dumbre
Published: August 2017

Background:

Tuberculosis of the foot and ankle still remains to be a significant problem, especially in the developing countries, and with an increase in incidence in immunosuppressed patients. Treatment is mainly medical using multidrug chemotherapy; surgical interventions range from biopsy, synovectomy and debridement, to joint preserving procedures like distraction in early cases, and arthrodesis of hindfoot joints and the ankle in advanced disease with joint destruction.

Surgical Options: All procedures should be done after initiating appropriate medical management. The ankle is the commonest joint needing intervention, followed by the subtalar and talo-navicular joint. Forefoot TB limited to the bone rarely needs surgical intervention except when the infective focus is threatening to invade a joint. Articular disease can spread rapidly, so early diagnosis and treatment can influence the outcome. Surgical interventions may need to be modified in the presence of sinuses and active disease; fusions need compression, and implants have to be chosen wisely. External fixators are the commonest devices used for compression in active disease, but intramedullary nails better stabilize pantalar arthrodesis. Arthroscopy has become a valuable tool for visualizing the ankle and hindfoot joints, and is an excellent adjunct for arthrodesis by minimally invasive methods.

Conclusion:

Although Osteoarticular Tb involving the foot and ankle is largely managed with chemotherapy, specific indications for surgical intervention exist. Timely done procedures could limit joint destruction, or prevent spread to adjacent joints. Fusions are the commonest procedure for sequelae of disease or for correcting residual deformity.
MR Imaging of the Achilles Tendon after Surgical Repair
Authors: Tam Kwok Fai , Lui Tun Hing
Published: August 2017

Achilles tendon tear is common and increasingly frequent. Magnetic resonance imaging (MRI) is the modality of choice for radiological evaluation. It is accurate to assess the status and integrity of the tendon with well documented features. In this article, the MR findings of a normal Achilles tendon as well as common diseases like insertional and noninsertional tendinosis, chronic tendinosis with marked lengthening, tendon rupture are illustrated. After a torn Achilles tendon receives surgical repair, it undergoes different stages of healing process including inflammatory, reparative and remodeling phases. Acute scar tissue in the surgical bed may share similar MR features of tendon re-rupture especially in the early healing phase because both are T2W hyperintense. The size of the gap may even appear larger than expected on T2W images possibly due to tendon remodeling. Understanding of the healing process in post-operative period may prevent overestimation of tendon gap and misdiagnosis of re-tear. We describe the MR features of the post-operative changes with serial studies in different months after surgery. The MR findings with the highlights of the expected sequential changes in normal healing process are illustrated in different cases. A case with surgical repair on a partial tear of Achilles tendon is also included.

Twenty healthy advanced pregnant crossbred (HF x K) cows of 2-4 parity were included in the study from 2 weeks prepartum to 8 weeks postpartum. They were equally divided in to control (routine farm feeding-RFF) and treatment (RFF plus area specific multi-minerals @ 50 g/h/d and bypass fat @ 100-200 g/h/d) groups to evaluate the effect of bypass fat and minerals supplementation on plasma metabolites and hormonal profile and postpartum fertility. The plasma levels of T3 increased (P less tha 0.01) on the day of calving and then abruptly dropped till day 14 postpartum as compared to levels at other periods, while T4 decreased (P less than 0.05) consistently throughout the study period particularly in control group. However, the influence of nutritional supplementation was found to be non-significant on both these hormones. The blood glucose levels were at peak concurrent to highest plasma cortisol on the day of calving. The cows under supplemented group had significantly (p less than 0.01) higher mean blood glucose (64.51±3.10 vs 59.13±3.06 mg/dl) and cortisol (16.19±2.51vs 11.23±1.34 ng/ml)than the control cows. The mean plasma levels of NEFA increased from day 14 prepartum to the highest (p less than 0.01) on the day of calving and thereafter reduced in postpartum days in both the groups with significantly higher mean value in supplemented than control group (0.58±0.09 vs 0.47±0.07 mmol/l). The prepartum plasma BHBA also increased as parturition approached, continued to increase further in the early postpartum period to reach a peak (1.21±0.09 and 0.87±0.04 mmol/l for control and treatment group) (p less than 0.01) on day 14, and thereafter decreased. In general, the plasma NEFA, BHBA, cortisol and glucose levels were found to be higher in the cows of nutrient supplemented group which had lesser time intervals for expressing first postpartum estrus and service period with better pregnancy rate. Thus the nutrient supplementation during transition period was beneficial in maintaining energy status of the cows and improved reproductive performance postpartum.

The morphological and morphometrical study of mandibles of hyena was carried out at Sakkarbaug Zoo, Junagadh (Gujarat). The average weight, length and width of mandible was 0.221 kg, 14.25 cm and 1.84 cm, respectively. The mandible was formed by two symmetrical halves fused rostrally by symphysis. The average length of symphysis mandibularis was 4.75 cm. The alveolar border presented six alveoli for lower incisors, two large deep alveoli for canine teeth, three alveoli for premolars and one for molar teeth. The diastemal mandibular length was 2.69 cm. The mental foramen was one. The mandibular height up to condylar and coronoid processes were 9.16 and 6.74 cm, respectively. The distance of mandibular foramen from posterior border was 3.22 cm. The angular process was placed at caudal border of horizontal ramus and found pointed and laterally curved. The average length of angular process was 1.23 cm.
