A Study of Crowdsourcing in Undergraduate Entrepreneurship Education
Crowdsourcing is an approach to harness knowledge and support from crowds using online platforms. Its use occurs within businesses and academia. Small businesses especially derive value from crowdsourcing because entrepreneurs have startup costs as well as time challenges to bring services/products to market. Entrepreneurs may also seek innovation and authenticity to differentiate from competitors. Since crowdsourcing offers these benefits, the researchers queried faculty from public and private universities who taught undergraduate classes in entrepreneurship to explore teaching methods utilized as well as specific aspects of crowdsourcing that were included. Researchers analyzed the resulting crowdsourcing gaps as well as crowdsourcing teaching challenges. Based upon their findings, new crowdsourcing learning activities and strategies were developed such that undergraduate entrepreneurship students may further benefit from crowdsourcing
Marketing Ethics: A Study of Significance Within National Professional Associations
Professional associations are expected to maintain a reasonable standard of behavior regarding how they market to their service bases. Prior research indicates that the use of written marketing ethics is not standardized and that business codes of ethics are a potential base for a universal code of marketing ethics from which all professionals could draw. We use document analysis to review several professional associationsâ codes of conduct across several industries and quantify the mention of marketing ethics within each code to identify and explore gaps. The review found that some associationsâ codes had significant representation, and others had a minimal or nonexistent representation of marketing ethics. Our findings also indicate that several external forces may determine the presence of marketing ethics and that such sporadic inclusion of marketing ethics indicates a necessity to develop and implement marketing ethics to protect professional and organizational integrity and market and consumer interests
Content and Face Validity of the Evaluation Tool of Health Information for Consumers (ETHIC): Getting Health Information Accessible to Patients and Citizens
Background: Health information concerns both individualsâ engagement and the way services and professionals provide information to facilitate consumersâ health decision making. Citizensâ and patientsâ participation in the management of their own health is related to the availability of tools making health information accessible, thus promoting empowerment and making care more inclusive and fairer. A novel instrument was developed (Evaluation Tool of Health Information for ConsumersâETHIC) for assessing the formal quality of health information materials written in Italian language. This study reports ETHICâs content and face validity. Methods: A convenience sample of 11 experts and 5 potential users was involved. The former were requested to evaluate relevance and exhaustiveness, the latter both readability and understandability of ETHIC. The Content Validity Index (CVI) was calculated for ETHICâs sections and items; experts and potential usersâ feedback were analyzed by the authors. Results: All sections and most items were evaluated as relevant. A new item was introduced. Potential users provided the researchers with comments that partly confirmed ETHICâs clarity and understandability. Conclusions: Our findings strongly support the relevance of ETHICâs sections and items. An updated version of the instrument matching exhaustivity, readability, and understandability criteria was obtained, which will be assessed for further steps of the validation process
Allergy to polyethilenglicole of anti-sars cov2 vaccine recipient: A case report of young adult recipient and the management of future exposure to sars-cov2
The main contraindication to the anti-SARS CoV2 vaccine is an anaphylactic reaction to a vaccine component. The need to vaccinate allergic people who are at higher risk can be of public health interest and this report shows a case of an allergic reaction to PEG of a HCW who had received the first dose of anti-SARS CoV2 vaccine. For 5 h after the administration of the vaccine, she had the appearance of erythematous spots on the face and neck, and a feeling of a slurred mouth and hoarseness. In order to treat the event, she was administered 8 mg intravenous dexamethasone, 1 vial intravenous chlorphenamine maleate, 250 mL intravenous 0.9% NaCl, and conventional oxygen therapy (2 L/min) with complete resolution of the suspected adverse drug reaction. According to the contraindication to the cutaneous test for this patient, BAT was used for further investigations. The patient who suffered the adverse reaction to the COVID-19 vaccine and other five allergic patients who did not report any adverse reaction after the vaccination were tested. There was a significant activation of the vaccine-reactive patientâs basophils with 14.79 CD203chigh% at the concentration of 0.2 mg/mL, while other patients were negative. People who have a confirmed reaction to a vaccine component should undergo further investigation to discover other possible cross-reactions and select the right vaccine to immunize them
Hybrid III-V/Silicon photonic circuits embedding generation and routing of entangled photon pairs
The demand for integrated photonic chips combining the generation and
manipulation of quantum states of light is steadily increasing, driven by the
need for compact and scalable platforms for quantum information technologies.
While photonic circuits with diverse functionalities are being developed in
different single material platforms, it has become crucial to realize hybrid
photonic circuits that harness the advantages of multiple materials while
mitigating their respective weaknesses, resulting in enhanced capabilities.
Here, we demonstrate a hybrid III-V/Silicon quantum photonic device combining
the strong second-order nonlinearity and compliance with electrical pumping of
the III-V semiconductor platform with the high maturity and CMOS compatibility
of the silicon photonic platform. Our device embeds the spontaneous parametric
down-conversion (SPDC) of photon pairs into an AlGaAs source and their
subsequent routing to a silicon-on-insulator circuitry, within an evanescent
coupling scheme managing both polarization states. This enables the on-chip
generation of broadband telecom photons by type 0 and type 2 SPDC from the
hybrid device, at room temperature and with internal pair generation rates
exceeding for both types, while the pump beam is strongly
rejected. Two-photon interference with 92% visibility (and up to 99% upon 5 nm
spectral filtering) proves the high energy-time entanglement quality
characterizing the produced quantum state, thereby enabling a wide range of
quantum information applications on-chip, within an hybrid architecture merging
the assets of two mature and highly complementary platforms in view of
out-of-the-lab deployment of quantum technologies
Asymmetric Primitive-Model Electrolytes: Debye-Huckel Theory, Criticality and Energy Bounds
Debye-Huckel (DH) theory is extended to treat two-component size- and
charge-asymmetric primitive models, focussing primarily on the 1:1 additive
hard-sphere electrolyte with, say, negative ion diameters, a--, larger than the
positive ion diameters, a++. The treatment highlights the crucial importance of
the charge-unbalanced ``border zones'' around each ion into which other ions of
only one species may penetrate. Extensions of the DH approach which describe
the border zones in a physically reasonable way are exact at high and low
density, , and, furthermore, are also in substantial agreement with
recent simulation predictions for \emph{trends} in the critical parameters,
and , with increasing size asymmetry. Conversely, the simplest
linear asymmetric DH description, which fails to account for physically
expected behavior in the border zones at low , can violate a new lower bound
on the energy (which applies generally to models asymmetric in both charge and
size). Other recent theories, including those based on the mean spherical
approximation, have predicted trends in the critical parameters quite opposite
to those established by the simulations.Comment: to appear in Physical Review
