Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).
AI Trends in Creative Operations 2024 by Artwork Flow.pdfmarketingartwork
Creative operations teams expect increased AI use in 2024. Currently, over half of tasks are not AI-enabled, but this is expected to decrease in the coming year. ChatGPT is the most popular AI tool currently. Business leaders are more actively exploring AI benefits than individual contributors. Most respondents do not believe AI will impact workforce size in 2024. However, some inhibitions still exist around AI accuracy and lack of understanding. Creatives primarily want to use AI to save time on mundane tasks and boost productivity.
Organizational culture includes values, norms, systems, symbols, language, assumptions, beliefs, and habits that influence employee behaviors and how people interpret those behaviors. It is important because culture can help or hinder a company's success. Some key aspects of Netflix's culture that help it achieve results include hiring smartly so every position has stars, focusing on attitude over just aptitude, and having a strict policy against peacocks, whiners, and jerks.

5 Public speaking tips from TED - Visualized summarySpeakerHub
From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world.

Google's Just Not That Into You: Understanding Core Updates & Search IntentLily Ray
1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework.
2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections.
3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.

de fluor en el suministro de agua, ha proporcionado los resultados siguientes:
Comunidad Nº niños sin caries Nº niños con caries
A 38 87
B 8 117
C 30 95
D 44 81
E 64 61
F 32 93
H0: Las incidencia de caries es igual en las seis ciudades (las poblaciones son homogeneas)
H1: Las incidencia de caries no es igual en las seis ciudades (las poblaciones no son
homogeneas)
6. Data weight cases
Cargar de esta manera los resultados, al hacer weight cases se esta
consiguiendo que la tabla se despliegue como una base de datos completa a
partir del cual se han resumido los datos en la tabla

9. CHI CUADRADO (CRITERIO DE INDEPENDENCIA)
Una muestra aleatoria de 200 adultos se clasifican de acuerdo al sexo y al
número de horas que miran televisión durante la semana las frecuencias se
dan en la siguiente tabla:
Nº de horas que miran TV
Menos de 15 horas Al menos 15 horas
Hombre 55 45
Mujer 40 60
Con esta información, ¿se puede concluir que el tiempo utilizado para ver tv es
independiente del sexo? use α= 0.05
Ho : El sexo es independiente de las horas de ver televisión
H1 : El sexo y las horas de ver televisión estan relacionadas

permanecen màs tiempo mirando TV
13. ¿Como se calcula el chi cuadrado?
Trabaja en base a valores observados valores esperados
El valor esperado para cada celda de la tabla de contingencia se
obtiene multiplicando el total marginal de columna por el total
marginal de la fila divido por el total
Luego se calcula un valor chi para cada celda el cual se obtiene
restando el valor observado menos el valor esperado , esta
diferencia se eleva al cuadrado y se divide por el valor esperado.
Finalmente se suman todos los valores chi de todas las celdas y se
obtiene el chi cuadrado
Se buscara en la tabla de chi el area que le corresponde según los
grados de libertad
Los grados de libertad se obtiene de multiplicar numero de filas
menos 1 por numero de columnas menos 1

La frecuencia mínima esperada es 24.00.
Siempre debe verse este valor, si el 25% o mas de celdas tiene valor esperado
menor que 5, no debe sacarse conclusiones, pues hay mucha posibilidad que la
conclusión sea errónea, en este caso solo se presenta la tabla pero no se
concluye
En ocasiones es necesario agrupar categorías para evitar este problema y es
conveniente que no haya muchas categorías
